Description

  The present invention relates to a processing apparatus that performs predetermined processing such as filtration processing on liquid and other various fluids.

  Conventionally, in a substrate processing tank that immerses a semiconductor substrate or the like and performs an etching treatment or the like, the processing liquid overflows (overflows) from the substrate processing tank and is collected. For example, Patent Document 1 discloses that the substrate is returned to the substrate processing tank and reused.

  Also, in wastewater treatment that purifies various wastewaters, the polymer flocculant is introduced to float and separate the oil contained in the wastewater as oil-impregnated scum and collect it with a conveyor-type filter. (For example, refer to Patent Document 2).

  However, in the filtration method as described in Patent Document 1 above, since the pump and the filter are arranged in the middle of the pipeline, when the filter suddenly becomes clogged, There was a problem that the pressure in the pipe line suddenly increased, and the pump and the joint part of the pipe line might be damaged. For this reason, it is not only necessary to constantly measure the clogging of the filter by constantly measuring the pressure and flow rate in the pipe line, but depending on the nature of the processing liquid, the processing liquid leaked due to damage etc. Therefore, there is a problem that the maintenance management cost rises together with the equipment cost.

  In addition, in the wastewater treatment method as described in Patent Document 2, not only labor and cost are required for introducing the polymer flocculant, but also problems such as clogging of the filter can be easily caused. Since it causes overflow, it is necessary to monitor and clean the filter frequently and to take countermeasures against leakage, which also increases the equipment cost and the maintenance cost.

  Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

  First, the structure of the processing apparatus 1 according to the present embodiment will be described. FIG. 1 is a schematic cross-sectional view showing an example of the processing apparatus 1. The processing apparatus 1 of this embodiment takes out the to-be-processed fluid 100 from the storage tank 110 which is the storage area | region which stores the to-be-processed fluid 100 of a liquid, performs a filtration process, and stores the to-be-processed fluid 100 after a process into the storage tank 110. It is something to return to.

  As shown in the figure, the processing apparatus 1 includes a processing region 10 for subjecting the fluid 100 to be treated to filtration, a discharge port 20 for returning the treated fluid 100 after processing into the storage tank 110, and An overflow port 30 for returning the treated fluid 100 overflowed (overflow) from the processing region 10 into the storage tank 110 and a supply for supplying the treated fluid 100 from the storage tank 110 into the processing region 10 And a rotating body 40.

  The processing region 10 is an internal space of the box 12 that is disposed above the storage tank 110, and is a space that is substantially isolated from the storage tank 110 by the box 12. The box 12 includes an upper wall 12a that covers the processing region 10 from above, a bottom wall 12b that covers the processing region 10 from below, a side wall 12c that connects the upper wall 12a and the bottom wall 12b, and covers the processing region 10 from the side. , Is composed of. The box 12 is disposed on the upper part of the storage tank 110 via the support member 14, and the bottom wall 12 b and a part of the lower side of the side wall 12 c are immersed in the fluid 100 to be processed in the storage tank 110. It has become.

  A filter 16 for filtering the fluid 100 to be processed and removing impurities and the like is disposed in the processing region 10. More specifically, the filter 16 is disposed so as to partition the processing region 10 into a first chamber 10a on the supply rotator 40 side and a second chamber 10b on the discharge port 20 side. That is, in the processing apparatus 1 of the present embodiment, the fluid 100 to be processed flows into the first chamber 10a by the supplying rotator 40 first, then passes through the filter 16 and is filtered, and then into the second chamber 10b. It flows in, finally passes through the discharge port 20 and returns to the storage tank 110 again.

  In the present embodiment, three filters 16 having different eye roughnesses are arranged in the processing region 10. The filter 16 can be easily removed through a door (not shown) provided on the upper wall 12a, and maintenance such as cleaning and replacement is extremely easy. Instead of providing a door on the upper wall 12a, an opening may be provided in the upper wall 12a, and the filter 16 may be removed through this opening. Further, the upper wall 12a may be omitted, and the upper portion of the processing region 10 may be opened.

  The discharge port 20 is an opening provided in the bottom wall 12b of the box body 12, and is configured to communicate the second chamber 10b and the storage tank 110. The discharge port 20 may be provided on the side wall 12c of the box 12.

  The overflow port 30 is an opening provided on the side wall of the box 12 on the first chamber 10 a side, and is provided above the discharge port 20. In the present embodiment, by disposing the box 12 on the upper part of the storage tank 110, the fluid 100 to be processed that has flowed out of the overflow port 30 falls into the storage tank 110 as it is.

  That is, in the processing apparatus 1 of the present embodiment, even when the flow rate that can pass through the filter 16 is extremely reduced due to the clogging of the filter 16, the fluid 100 to be processed enters the storage tank 110 through the overflow port 30. It returns as it is, and no special measures against leakage are required. Note that the overflow port 30 may be configured by opening all or part of the upper portion of the box 12. Moreover, you may make it provide in the overflow port 30 appropriate piping, a soot, etc. which guide | induce the to-be-processed fluid 100 in the storage tank 110. FIG.

  The supply rotator 40 is driven and rotated by a driving device 50 such as a motor, thereby sucking the fluid 100 to be processed in the storage tank 110 and discharging it into the first chamber 10 a of the processing region 10. . In the present embodiment, the supply rotating body 40 is also provided with a function of stirring the fluid 100 to be processed in the storage tank 110. The supply rotator 40 is disposed in a state of being inserted into a substantially circular rotator opening 18 provided in the bottom wall 12b of the box 12, and includes a driving device 50 fixed to the upper wall 12a. They are connected via a drive shaft 60.

  FIG. 2A is a plan view of the supplying rotator 40, and FIG. 2B is a front view (side view) of the supplying rotator 40. FIG. As shown in these drawings, the main body 41 of the supplying rotator 40 is formed in a substantially cylindrical shape, and the surface of the main body 41 has a substantially circular upper surface 41a and a bottom surface 41b, and side surfaces that are outer peripheral surfaces. 41c.

  As shown in FIG. 2B, the supply rotator 40 is disposed in a state of being inserted into the rotator opening 18 provided in the bottom wall 12 b of the box 12. Accordingly, the upper surface 41 a of the main body 41 and the upper surface 41 a side of the side surface 41 c are the processing region inner surface 40 a located in the processing region 10. Further, the bottom surface 41 b of the main body 41 and the portions of the side surface 41 c on the bottom surface 41 b side are processing area outer surfaces 40 b located outside the processing area 10. An appropriate sealing mechanism such as packing or labyrinth may be provided between the supply rotator 40 and the rotator opening 18 as necessary.

  A supply suction port 42 and a plurality of supply discharge ports 44 are provided on the surface of the main body 41, and the supply suction port 42 and each supply discharge port 44 are formed inside the main body 41. A supply flow passage 46 is provided. A plurality of stirring suction ports 43 and a plurality of stirring discharge ports 45 are further provided on the surface of the main body 41, and a stirring flow passage 47 connecting the stirring suction port 43 and the stirring discharge port 45 is provided in the main body 41. Is provided inside.

  A connection portion 48 to which the drive shaft 60 is connected is provided at the center of the upper surface 41 a of the main body 41. Therefore, the supplying rotator 40 is driven by the driving device 50 and is configured to rotate about the central axis C as a rotation axis. In addition, the connection method of the drive shaft 60 and the connection part 48 may be any known method such as a set screw, engagement, or clamp.

  The supply inlet 42 is provided substantially at the center of the bottom surface 41b, which is a part of the processing region outer surface 40b, and is directed in the same direction as the central axis C. The supply discharge port 44 is provided on the upper surface 41a side of the side surface 41c which is a part of the processing region inner surface 40a. In the present embodiment, four supply discharge ports 44 are provided, and each supply discharge port 44 is located outside the main body 41 in the radial direction (centrifugal direction) with respect to the supply suction port 42 (central axis C). At a position away from the center axis C in a direction perpendicular to the central axis C). Further, the supply discharge port 44 is directed in a direction substantially orthogonal to the central axis C.

  The supply flow passage 46 is formed as a tunnel-like passage connecting one supply suction port 42 and four supply discharge ports 44. Accordingly, the supply flow passage 46 straightly travels along the direction of the central axis C from the supply suction port 42 and then branches into four, and travels straight in the centrifugal direction of the main body 41 to reach each discharge port 44. Is formed.

  The agitation suction port 43 is provided on the bottom surface 41b, which is a part of the processing region outer surface 40b, like the supply suction port 42. In the present embodiment, the four stirring inlets 43 are arranged on the circumference centered on the central axis C at equal intervals. Further, the stirring inlet 43 is directed in the substantially same direction as the central axis C. Unlike the supply discharge port 44, the stirring discharge port 45 is provided on the bottom surface 41b side of the side surface 41c that is a part of the processing region outer surface 40b. In the present embodiment, four agitation discharge ports 45 are provided, and each agitation discharge port 45 is located at a position (center axis C) that is radially outward (centrifugal) of the main body 41 with respect to the agitation suction port 43. At a position away from the center axis C in a direction perpendicular to the central axis C). In addition, the stirring discharge port 45 is oriented in a direction substantially orthogonal to the central axis C, and is disposed so that the position in the circumferential direction is substantially the same as the supply discharge port 44.

  The stirring flow passage 47 is formed as a tunnel-shaped passage that connects one stirring suction port 43 and one stirring discharge port 45. Accordingly, four stirring flow passages 47 are formed inside the main body 41. In the present embodiment, each of the agitating flow passages 47 goes straight from the agitating suction port 43 along the direction of the central axis C and then bends at a right angle, and then goes straight in the centrifugal direction of the main body 41 to the agitating discharge port 45. Shaped to reach.

  In the following description, the supply suction port 42 and the stirring suction port 43 may be collectively referred to as suction ports 42 and 43. Similarly, the supply discharge port 44 and the stirring discharge port 45 may be collectively referred to as discharge ports 44 and 45, and the supply flow passage 46 and the stirring flow passage 47 may be collectively referred to as flow passages 46 and 47.

  When the supply rotating body 40 is immersed in the processing target fluid 100 and rotated around the central axis C, the processing target fluid 100 that has entered the flow passages 46 and 47 also rotates together with the supplying rotating member 40. . Then, centrifugal force acts on the fluid 100 to be processed in the flow passages 46 and 47, and the fluid 100 to be processed in the flow passages 46 and 47 rotates for supply as shown in FIGS. 2 (a) and 2 (b). It flows toward the radially outer side of the body 40.

  Since the discharge ports 44 and 45 are provided on the radially outer side of the supply rotator 40 with respect to the suction ports 42 and 43, a centrifugal force stronger than that of the suction ports 42 and 43 acts on the discharge ports 44 and 45. Become. Accordingly, the fluid 100 to be treated flows from the suction ports 42 and 43 toward the discharge ports 44 and 45 as long as the supply rotator 40 rotates. That is, the fluid 100 to be processed in the flow passages 46 and 47 is ejected from the discharge ports 44 and 45, and the external fluid 100 to be processed is sucked into the flow passages 46 and 47 from the suction ports 42 and 43. .

  The supply suction port 42 is provided in the processing region outer surface 40b, and the supply discharge port 44 is provided in the processing region inner surface 40a. Therefore, as long as the supply rotator 40 is rotating, the fluid 100 to be processed outside the processing region 10 is sucked from the supply suction port 42, passes through the supply flow passage 46, and is processed from the supply discharge port 44. It will be ejected into the region 10. That is, the fluid 100 to be processed in the storage tank 110 is supplied into the processing region 10 by the rotating supply rotating body 40.

  On the other hand, both the stirring inlet 43 and the stirring outlet 45 are provided on the processing region outer surface 40b. Accordingly, the fluid 100 to be treated sucked into the stirring suction port 43 by the rotation of the supply rotating body 40 is ejected from the stirring discharge port 45 into the storage tank 110 after passing through the stirring flow passage 47. . As a result, the fluid 100 to be processed outside the processing region 10, that is, in the storage tank 110, flows toward the bottom surface 41 b having the supply suction port 42 and the stirring suction port 43, and the side surface 41 c having the stirring discharge port 45. The flow that spreads radially from the bottom will occur. The flow toward the bottom surface 41 b becomes a relatively strong swirling flow due to the rotation of the stirring inlet 43.

  In the present embodiment, in this way, not only the supply target fluid 100 is supplied from the storage tank 110 into the processing region 10 by the supply rotating body 40, but also two types of flow are generated in the target fluid 100 in the storage tank 110. Thus, the fluid 100 to be processed in the storage tank 110 is appropriately agitated. As a result, it is possible to efficiently perform the filtering process on the fluid 100 to be processed, even though the configuration is very simple.

  In the present embodiment, the main body 41 is configured in a substantially cylindrical shape, but the shape of the main body 41 is not limited to this, and for example, any other shape such as a spherical shape, a hemispherical shape, a polygonal column shape, etc. Can be adopted. The shapes (cross-sectional shapes) of the suction ports 42 and 43 and the discharge ports 44 and 45 are not limited to a circular shape, and may be other shapes such as an elliptical shape and a polygonal shape. Further, the cross-sectional shape of the flow passages 46 and 47 is not particularly limited, and the flow passages 46 and 47 may be configured in an appropriate shape according to the shape and position of the suction ports 42 and 43 and the discharge ports 44 and 45, the processing method, or the like. Can do.

  In the present embodiment, the flow passages 46 and 47 are formed in an L shape that bends at a substantially right angle for ease of processing, but the flow passages 46 and 47 are configured as smoothly curved curved passages. Alternatively, the suction ports 42 and 43 and the discharge ports 44 and 45 may be connected linearly. In addition, the suction ports 42 and 43 and the discharge ports 44 and 45 may be formed so as to be directed obliquely with respect to the central axis C or the direction orthogonal to the central axis C.

  Further, in the present embodiment, the strength of the main body 41 is increased by configuring the portions other than the flow passages 46 and 47 of the main body 41 to be solid, but the portions other than the flow passages 46 and 47 of the main body 41 are increased. You may make it comprise in hollow shape. Moreover, the material which comprises the main body 41 is not specifically limited, For example, appropriate materials according to use conditions, such as a metal, ceramics, resin, rubber | gum, wood, etc., are employable.

  Next, the operation of the processing apparatus 1 will be described. FIG. 3 is a schematic sectional view showing the operation of the processing apparatus 1. As described above, the fluid 100 to be processed in the storage tank 110 flows into the processing region 10 by rotating the supply rotating body 40. As a result, the pressure in the processing region 10 increases, and the liquid level in the processing region 10 becomes higher than the liquid level in the storage tank 110. That is, a head difference occurs in the processing region 10 and the storage tank 110, and due to this head difference, the fluid 100 to be processed in the processing region 10 flows out from the discharge port 20 into the storage tank 110.

  As a result, as long as the supply rotator 40 is rotating in the processing region 10, the fluid 100 to be processed flows from the first chamber 10a through the filter 16 into the second chamber 10b almost constantly. As a result, the fluid to be treated 100 is filtered. Further, in the first chamber 10a, a complicated flow including a swirling flow is generated by the rotation of the main body 41 of the supply rotating body 40 and the supply discharge port 44. Will be dispersed appropriately. As a result, impurities and the like are not concentrated on a specific part of the filter 16, so that the filtration process can be performed efficiently and the life of the filter can be extended.

  On the other hand, in the storage tank 110, in addition to the flow from the discharge port 20, a complicated circulation flow is generated from the swirling flow toward the supply rotator 40 from below and the flow spreading radially from the supply rotator 40. Become. That is, since the fluid 100 to be processed in the storage tank 110 flows into the processing region 10 in a sufficiently agitated state, the filtration process is performed quickly and efficiently.

  In particular, in the present embodiment, the supply rotating body 40 is provided with the agitation suction port 43, the agitation discharge port 45 and the agitation flow passage 47, so that the swirl flow generated by the suction to the agitation suction port 43 is caused. The sediment at the bottom of the storage tank 110 can be appropriately rolled up and fed into the treatment area 10 and the stirring action can be exerted on a farther area in the storage tank 110 by the ejection from the stirring outlet 45. Is possible. That is, since impurities and the like present in every corner of the storage tank 110 can be reliably sent into the processing region 10, it is possible to perform the filtration process more quickly and efficiently.

  In addition, unlike the turbine blade and the propeller blade, the supply rotor 40 has a shape that is not easily damaged. Therefore, even when the fluid to be processed 100 including gravel is subjected to a filtration process, the supply rotor 40 is damaged. It is difficult for problems to occur. That is, the filtration process can be performed quickly and reliably regardless of the state of the fluid 100 to be processed.

  Next, other forms of the processing apparatus 1 will be described. First, FIG. 4A is a plan view showing an example in which one stirring suction port 43 is provided and a plurality of supply suction ports 42 are provided. In the above example, the case where one supply suction port 42 is provided at the center and a plurality of stirring suction ports 43 are provided around it is shown. However, one stirring suction port 43 is provided at the center and the surroundings are provided. A plurality of supply inlets 42 may be provided. Depending on the state of the fluid 100 to be processed, supply and stirring may be more efficient in this way.

  In the example shown in FIG. 4A, the circumferential positions of the supply suction port 42 and the supply discharge port 44 are shifted so that interference between the supply flow passage 46 and the stirring flow passage 47 is avoided. However, only one of the supply suction port 42 and the supply discharge port 44 may be shifted, or the supply flow passage 46 or the stirring flow passage 47 may be bypassed to avoid mutual interference. It may be.

  FIG. 4B is a plan view showing an example in which a plurality of supply suction ports 42 and a plurality of stirring suction ports 43 are provided. As described above, a plurality of supply suction ports 42 and a plurality of stirring suction ports 43 may be provided. In this case, the swirling flow toward the suction ports 42 and 43 can be made stronger.

  In the example shown in FIG. 4B, the supply suction ports 42 and the stirring suction ports 43 are alternately arranged on the same circumference with the central axis C as the center. Other arrangement configurations, such as arranging the suction port 42 and the stirring suction port 43 on different circumferences, may be adopted.

  FIG. 4C is a front view (side view) showing an example in which the supply suction port 42 and the stirring suction port 43 are also used as one another. As described above, a part of the supply suction port 42 and the stirring suction port 43, and the supply flow passage 46 and the stirring flow passage 47 may be used together. Depending on the state of the fluid 100 to be processed, supply and stirring may be more efficient in this way.

  In this manner, by appropriately setting the arrangement configuration of the suction ports 42 and 43 and the discharge ports 44 and 45, it is possible to perform an efficient filtration process according to the state of the fluid 100 to be processed. In the above example, one or four suction ports 42 and 43 and discharge ports 44 and 45 are shown. However, the number of suction ports 42 and 43 and discharge ports 44 and 45 is limited to these. Needless to say, other numbers may be used.

  FIGS. 5A and 5B are front views (side views) showing an example in which the radial dimensions of the processing region inner surface 40a and the processing region outer surface 40b of the supply rotator 40 are made different from each other. is there. In this manner, the distance from the central axis C to the supply discharge port 44 and the distance from the central axis C to the stirring discharge port 45 are appropriately set, and the centrifugal force acting on the supply and the stirring action are affected. The centrifugal force to be adjusted can be adjusted appropriately. That is, since the supply force and the stirring force by the supply rotator 40 can be appropriately balanced, quick and efficient filtration can be performed regardless of the size and shape of the processing region 10 and the storage tank 110. .

  FIGS. 6A and 6B are front views (side views) showing an example in which a stirring rotator 70 is provided separately from the supply rotator 40. As described above, the main body 41 of the supply rotator 40 is provided with only the supply suction port 42, the supply discharge port 44 and the supply flow passage 46, and is dedicated to supply, and the main body 71 (main body for stirring) is used for stirring. A stirring-use rotating body 70 that is provided only with the suction port 43, the stirring discharge port 45, and the stirring flow passage 47 may be separately provided.

  In this case, as shown in FIG. 6 (a), a stirring rotator 70 may be connected to the extended drive shaft 60, or as shown in FIG. 6 (b), a supplying rotator. 40 may be configured such that the rotating body for stirring 70 can be directly connected. By doing in this way, since the combination of the supply rotary body 40 and the stirring rotary body 70 can be easily changed, the balance between the supply force and the stirring force can be easily adjusted. In the example shown in FIG. 6B, the stirring rotary body 70 is provided with a part of the supply inlet 42 and the supply flow passage 46, and the stirring rotary body 70 is connected to the supply rotary body 40. In addition, they may communicate with a part of the supply flow passage 46 provided in the supply rotating body 40 and the supply discharge port 44.

  In addition, when the rotating body for stirring 70 is not necessary, this may be omitted. That is, the processing apparatus 1 may include only the supply rotating body 40 provided with only the supply suction port 42, the supply discharge port 44, and the supply flow passage 46. Also in this case, the inside of the storage tank 110 can be appropriately stirred by the flow toward the supply suction port 42 and the flow from the discharge port 20.

  FIG. 7 is a schematic cross-sectional view showing an example in which the flow resistor 80 is provided in the storage tank 110 and the guide member 90 is provided in the processing region 10. The flow resistor 80 becomes a resistance of the flow toward the supply rotator 40 in the storage tank 110, and is disposed on the opposite side of the processing region 10 in the central axis C direction with respect to the supply rotator 40. . The shape and arrangement of the flow resistor 80 are not particularly limited, and an appropriate shape and arrangement according to the state of the fluid 100 to be processed and the size and shape of the storage tank 110 can be employed. In the example shown in FIG. 7, the flow resistor 80 is fixed to the box 12 via the rod-shaped support member 82. However, the flow resistor 80 is fixed to other parts such as the bottom 112 of the storage tank 110. Alternatively, the flow resistor 80 may be rotated while being fixed to the supply rotator 40.

  In this manner, by arranging the flow resistor 80, the flow toward the supplying rotator 40 can be appropriately disturbed, so that the stirring efficiency can be increased. In addition, as shown in FIG. 7, by arranging the substantially flat flow resistor 80 in the vicinity of the bottom 112 of the storage tank 110, the swirling flow in the vicinity of the bottom 112 can be appropriately disturbed. It is possible to prevent a problem such that the bottom 112 is worn when impurities such as heavy gravel continue to turn at substantially the same place.

  The guide member 90 guides the flow from the supply discharge port 44 in an appropriate direction in the first chamber 10 a of the processing region 10, and from the outer peripheral side of the supply rotating body 40, that is, from the supply discharge port 44. Is also arranged on the outer side in the centrifugal direction from the central axis C. Thus, by appropriately arranging the guide member 90, for example, it is possible to prevent the flow from the supply discharge port 44 from being concentrated on a specific portion of the filter 16 or the box body 12. It is possible to prevent damage to the box body 12 and increase the efficiency of the filtration process. In addition, depending on the state of the fluid 100 to be processed and impurities, the filter 16 is prevented from being clogged by causing the flow from the supply discharge port 44 to collide with the filter 16 directly or via the guide member 90. It may be.

  In addition, the shape and arrangement | positioning of the guidance member 90 are not specifically limited, The appropriate | suitable shape and arrangement | positioning according to the shape of the process area | region 10, the structure of the filter 16, etc. are employable. Further, the guide member 90 may be fixed to the box body 12 or may be fixed to the supply rotating body 40. 7 shows an example in which both the flow resistor 80 and the guide member 90 are provided in the processing apparatus 1, but it goes without saying that only one of them may be provided in the processing apparatus 1. . Further, one each of the flow resistor 80 and the guide member 90 may be provided, or a plurality of the guide members 90 may be provided.

  FIG. 8 is a schematic cross-sectional view showing an example in which a front chamber 10c is provided in front of the first chamber 10a in the processing region 10 and the processing region inner surface 40a of the supply rotating body 40 is disposed in the front chamber 10c. FIG. In this example, an additional side wall 12d and an additional bottom wall 12e are provided below the box body 12 to form the front chamber 10c, and the front chamber 10c and the first chamber 10a are communicated with each other through the connection port 10d. . The rotating body opening 18 is provided in the additional bottom wall 12e, and the supplying rotating body 40 is arranged in a state of being inserted through the opening 18 for the rotating body. That is, the fluid 100 to be processed once flows into the front chamber 10c and then flows into the first chamber 10a.

  In this manner, the flow in the processing region 10 is controlled by, for example, causing the front chamber 10c to function as a buffer space by, for example, causing the fluid 100 to be processed to flow into the first chamber 10a after being taken into the front chamber 10c. It becomes possible. Depending on the state of the fluid 100 to be treated, the efficiency of the filtration process can be improved by providing the front chamber 10c in the treatment region 10 as described above.

  Alternatively, the front chamber 10c may be arranged separately from the first chamber 10a, and the front chamber 10c and the first chamber 10a may be connected via an appropriate pipe line or the like. Further, an intermediate chamber may be further provided between the front chamber 10c and the first chamber 10a, or a rear chamber may be provided after the second chamber 10b. That is, the processing area 10 may be divided into a plurality of chambers (spaces).

  FIG. 9 is a schematic cross-sectional view showing an example in which a discharge flow path 22 is provided between the processing region 10 and the discharge port 20. In this example, the discharge flow passage 22 is formed by extending the pipe 22 a from the bottom wall 12 b of the box 12, and the discharge port 20 is disposed at a position separated from the supply rotating body 40. The auxiliary discharge ports 20a are provided at three locations in the middle of the pipe 22a so that the processed fluid 100 after the filtration process flows into the storage tank 110 from a plurality of locations.

  As described above, by providing the discharge flow passage 22, the treated fluid 100 after the filtration treatment can be discharged to an appropriate position according to the size, shape, and the like of the storage tank 110. That is, by appropriately combining the flow from the discharge port 20 and the auxiliary discharge port 20a and the flow by the supply rotating body 40 and synergistically acting both, the inside of the storage tank 110 is appropriately stirred, thereby Efficiency can be increased.

  Note that a plurality of discharge flow paths 22 and discharge ports 20 may be provided, or a plurality of discharge ports 20 may be provided by branching the discharge flow paths 22 on the way. Needless to say, the auxiliary outlet 20a may be provided as necessary.

  FIG. 10 is a schematic cross-sectional view showing an example in which a carrier 120 carrying microorganisms is arranged in the processing region 10 instead of the filter 16. In this example, nets 24 and 32 for preventing outflow of the carrier 120 are provided at the discharge port 20 and the overflow port 30, respectively, and a plurality of carriers 120 carrying microorganisms are floated in the processing region 10. By doing so, it is possible to perform biological treatment of the fluid 100 to be treated within the treatment region 10. In this case, not only the fluid 100 to be processed in the storage tank 110 is appropriately stirred, but also the carrier 120 can be appropriately dispersed by the flow from the supply discharge port 44 in the processing region 10, which is efficient. Biological treatment can be performed.

  Furthermore, as shown in FIG. 10, for example, by providing a shaft flow passage 62 and an intake port 64 connected to the supply flow passage 46 in the drive shaft 60, outside air can be very easily supplied to the fluid 100 to be processed in the processing region 10. Therefore, even biological treatment using aerobic microorganisms can be performed more efficiently than before. In this case, the floating state of the carrier 120 may be adjusted by adjusting the position and number of the discharge ports 20 or by appropriately arranging the guide member 90. Further, for example, the stirring rotator 70 shown in FIG. 6A may be arranged in the processing region 10. Further, the carrier 120 may be fixed within the processing region 10.

  Thus, although the processing apparatus 1 is suitable when performing the filtration process with respect to the to-be-processed fluid 100, you may perform other various processes. For example, the processing apparatus 1 may perform processing such as aeration and deaeration on the processing target fluid 100 in the processing region 10, or may apply other objects to the processing target fluid 100 in the processing region 10. It may be one that is charged and subjected to a treatment such as dissolution or reaction. Further, the processing apparatus 1 may perform a process of exchanging heat between the fluid 100 to be processed and another heat medium in the processing region 10.

  FIG. 11 is a schematic cross-sectional view showing an example in which the processing region 10 and the storage tank 110 are not clearly partitioned. In this example, the outer periphery of the supply rotating body 40 is surrounded by the four filters 16 supported by the support members 14 and 16 a, and the region surrounded by the four filters 16 and the inside of the filter 16 are used as the processing region 10. In this example, the outer surface of the filter 16 from which the fluid 100 to be processed flows out becomes the discharge port 20, and the upper part of the filter 16 becomes the overflow port 30. Note that a gap may be provided between the filters 16 or may be closed.

  Thus, the processing area 10 does not have to be clearly isolated from the storage tank 110 (storage area), and depending on the type of processing, for example, a partition wall between the processing area 10 and the storage tank 110 May be provided only in necessary portions, or the filter 16 or the like may be used as a partition wall. By doing in this way, it becomes possible to further simplify the structure of the processing apparatus 1, and to reduce the cost and increase the degree of freedom of installation.
