Description

  The present invention relates to a rotating body for stirring and a stirring device for stirring, mixing, dispersing, and the like of liquids and other various fluids.

  Conventionally, for example, when two or more kinds of fluids are mixed or various powders added to the fluid are uniformly dispersed, a stirrer that rotates an impeller in the fluid is used. This impeller is generally provided with a propeller blade and a turbine blade, and agitation is performed by flowing a fluid by rotating.

  Such a stirrer is often used by being permanently installed in a tank containing a fluid, but in addition to this, for example, a handy type for stirring a paint etc. on the spot immediately before use is often used. in use. This handy type agitator is generally configured by providing an impeller at the tip of a drive shaft of a hand drill type drive device. Then, the user holds the drive device in both hands, inserts the impeller at the tip into a container in which an object to be stirred such as a paint is stored, rotates it, and performs stirring.

  However, this handy type stirrer is very dangerous because an impeller having a sharp blade tip is rotated at a high speed, and there is a problem that it requires careful handling. Also, if an impeller with many protrusions hits the container, or if the impeller causes fatigue failure, the tip of the impeller or part of the container is missing or scraped and mixed into the object to be stirred. There was a problem that it was easy to do.

  Also, since the impeller causes the material to be stirred to flow by colliding with the material to be stirred, in a stirrer equipped with an impeller, when the rotating impeller is put into the material to be stirred, or in the material to be stirred, the impeller When starting to rotate, there was a problem that the impeller was easily shaken by the reaction. For this reason, when the user is not operating the stirrer, situations such as hitting the impeller against the container or scattering the object to be stirred out of the container frequently occurred.

  In addition, in the impeller, when the agitated material contains sediment, the sediment cannot be dispersed well unless stirring is performed while the impeller is in contact with the bottom wall of the container. There has been a problem that debris and scraps generated by contact with the wall surface of the container are likely to be mixed into the object to be stirred.

  Moreover, in the stirrer provided with the impeller, there is a problem that the powder particles mixed in the object to be stirred may be pulverized by collision with the impeller. For this reason, it is difficult to sufficiently stir, for example, when it is not desired to make the mixed powder particles finer, such as a metallic paint.

  On the other hand, instead of using propeller blades and turbine blades, a mixer for a high-viscosity fluid in which an impeller is configured from a hexagonal cylindrical body and a plurality of holes are provided on a side surface has been proposed (for example, , See Patent Document 1).

JP-A-5-154368

  However, in the mixer for high-viscosity fluid described in Patent Document 1, since the outer shape of the impeller is a hexagonal column, the above-described problems have not been solved. Specifically, since the mixer described in Patent Document 1 has a plurality of corners on the outer wall, there is a high risk of rotation, and there is a high possibility of debris and scraping when hitting a container. Met.

  In addition, although the effect due to the outflow of fluid from the side hole is added, the object to be stirred is caused to flow mainly by causing the outer wall of the impeller to collide with the object to be stirred. It did not solve the problem of pulverization of the powder particles in the stirred product.

  Furthermore, because the volume inside the impeller is larger than the side hole, the flow velocity inside the impeller is low, and when used for a long time, the accumulated matter adheres to the impeller and accumulates, and the stirring ability is likely to be reduced. There was a problem.

  This invention is made | formed in view of such a situation, Comprising: It aims at providing the rotary body for stirring and stirring apparatus which can perform safe and efficient stirring irrespective of a use.

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

  First, the structure of the stirring rotating body 1 according to the embodiment of the present invention will be described. FIG. 1A is a plan view of the stirring rotator 1, and FIG. 1B is a front view of the stirring rotator 1. As shown in these drawings, the stirring rotator 1 includes a substantially hemispherical main body 10, a plurality of suction ports 12 provided on the surface of the main body 10, and a plurality of discharges provided on the surface of the main body 10. The outlet 14 is composed of a flow passage 16 formed in the main body 10 so as to connect the suction port 12 and the discharge port 14.

  In this example, the main body 10 has a substantially hemispherical shape, specifically, a shape in which one bottom surface 10a of the disk is formed into a spherical shape. At the center of the other bottom surface 10b of the main body 10, a connecting portion 18 to which a driving shaft 20 of a driving device such as a motor is connected is provided. Therefore, the central axis C of the main body 10 becomes the rotation axis. In addition, the connection method of the drive shaft 20 and the connection part 18 may be any known method such as a screw or engagement.

  In this embodiment, the strength of the main body 10 is increased by configuring the main body 10 other than the flow passage 16 to be solid. The material which comprises the main body 10 is not specifically limited, For example, a suitable material according to use conditions, such as a metal, ceramics, resin, rubber | gum, wood, etc., is employable. Since the main body 10 of the present embodiment is simple and easy to process, the main body 10 can be configured from a wide variety of materials without being limited by the manufacturing method.

  The suction port 12 is provided on the bottom surface 10 b on the opposite side of the connection portion 18 in the main body 10. In the present embodiment, the four suction ports 12 are arranged at equal intervals on a circumference centered on the central axis C, and are formed in the same direction as the central axis C. The discharge port 14 is provided on the side surface 10 c of the main body 10. In the present embodiment, the four discharge ports 14 are arranged at positions that are radially outward of the main body 10 with respect to the respective suction ports 12. Further, the discharge port 14 is formed in a direction orthogonal to the central axis C.

  The flow passage 16 is formed as a passage connecting one suction port 12 and one discharge port 14. Accordingly, four flow passages are formed in the main body 10. Each flow passage 16 is formed so as to straightly advance from the suction port 12 along the direction of the central axis C, then bend at a right angle, and straight forward toward the radially outer side of the main body 10 to reach the discharge port 14.

  In the present embodiment, the flow passage 16 is configured in this way, so that the suction port 12, the discharge port 14, and the flow passage 16 can be easily formed by drilling with a drill. Specifically, the suction port 12, the discharge port 14, and the flow passage 16 can be easily formed by drilling a hole from the position of the suction port 12 in the direction of the central axis C and drilling a hole from the position of the discharge port 14 toward the central axis C. Can be formed. In addition, in this embodiment, although the cross-sectional shape of the flow path 16 is comprised circularly, it is not limited to this, For example, it is good also as other cross-sectional shapes, such as an ellipse and a polygon.

  Next, the operation of the stirring rotating body 1 will be described. FIG. 2A is a plan view showing the operation of the stirring rotator 1, and FIG. 2B is a front view showing the operation of the stirring rotator 1. The stirring rotating body 1 is driven by the drive shaft 20 and rotates about the central axis C in the object to be stirred that is a fluid, thereby stirring the object to be stirred.

  When the stirring rotator 1 is immersed in the fluid and rotated, the fluid that has entered the flow passage 16 also rotates together with the stirring rotator 1. Then, centrifugal force acts on the fluid in the flow passage 16, and the fluid in the flow passage 16 flows toward the outside in the radial direction of the stirring rotating body 1 as shown in these drawings. Since the discharge port 14 is provided on the radially outer side of the main body 10 with respect to the suction port 12, a stronger centrifugal force acts on the discharge port 14 than on the suction port 12. Accordingly, the fluid flows from the suction port 12 toward the discharge port 14 as long as the stirring rotator 1 rotates. That is, the fluid in the flow passage 16 is ejected from the discharge port 14, and the external fluid is sucked into the flow passage 16 from the suction port 12. Thereby, in the fluid around the stirring rotator 1, a flow that radiates from the side surface 10 c with the discharge port 14 and a flow toward the tip of the stirring rotator 1 with the suction port 12 are generated. .

  Further, when the stirring rotator 1 is immersed in the fluid and rotated, the fluid near the surface of the stirring rotator 1 rotates together with the stirring rotator 1 due to the influence of viscosity. Accordingly, the centrifugal force also acts on the fluid near the surface of the stirring rotator 1, and as shown in these drawings, the fluid near the surface flows along the surface of the stirring rotator 1 to the side surface 10c and discharges it. It becomes an accompanying flow of the jet from the outlet 14.

  In the present embodiment, since the bottom surface 10b is formed in a spherical shape, the shape of the main body 10 has a shape in which the axial thickness gradually decreases outward in the radial direction. It is possible to smoothly merge the flow into the flow spreading radially from the side surface 10c. Further, by forming the bottom surface 10b in such a shape, a part of the flow toward the tip of the stirring rotator 1 smoothly flows to the side surface 10c along the bottom surface 10b, and the flow spreads radially from the side surface 10c. It is possible to join. As a result, the rotating body for stirring 1 can generate a powerful flow in the surrounding fluid, so that efficient stirring can be performed.

  3 (a) and 3 (b) and FIGS. 4 (a) and 4 (b) are schematic views showing an example of use of the stirring rotator 1. FIG. As shown in these figures, the stirring rotator 1 is connected to the drive shaft 20 of a drive device 30 such as a motor, and is immersed in an object to be stirred 50 that is a fluid contained in a container 40. Used in. The driving device 30 may be fixed to the container 40, a pedestal, or the like, or may be held and operated by a user.

By rotating the stirring rotator 1 by the driving device 30, a flow that radially spreads from the stirring rotator 1 and a flow toward the tip of the stirring rotator 1 are generated as described above. As a result, as shown in FIGS. 3A and 3B, a complicated circulation flow is generated in the stirring object 50, and the stirring object 50 is sufficiently stirred by this circulation flow. In the present embodiment, the cross section perpendicular to the rotation axis direction of the main body 10 is formed in a circular shape so that there is no portion that collides with the agitated object 50 during the rotation. Almost never occurs.

  In order to disperse the staying matter staying at the bottom of the container 40, the tip of the stirring rotating body 1 may be brought closer to the bottom of the container 400 as shown in FIG. By doing so, the staying material can be sucked up from the suction port 12 and ejected from the discharge port 14, and the staying material can be sufficiently dispersed in the stirring object 50. In addition, in the case where the staying matter staying at the corner of the container 40 is dispersed, the tip of the stirring rotor 1 may be brought closer to the corner of the container 400 as shown in FIG. . In the present embodiment, since the bottom surface 10b is formed in a spherical shape, the suction port 12 can be sufficiently brought close to a narrow corner portion.

In the present embodiment, the cross section perpendicular to the rotation axis direction of the main body 10 is formed in a circular shape and has no protrusions, so that the stirring rotor 1 is stirred even when it hits the wall surface of the container 40. The possibility that the rotating body 1 or the container 40 is damaged or scraped is reduced. For this reason, the rotating body 1 for stirring can be brought close to the wall surface of the container 40 with peace of mind, and it is possible to sufficiently stir all the corners of the container 40. Furthermore, fragments or shavings etc. of the rotating body for stirring 1 or the container 40 are not easily mixed into the object to be stirred 50.

  In the present embodiment, the suction port 12 is arranged slightly outside the center of the tip of the stirring rotator 1 (center axis C, which is the rotation axis), so that the tip of the stirring rotator 1 is placed on the wall surface of the container 40. Even when they are brought into contact with each other, the suction port 12 is prevented from being blocked. For this reason, the rotating body 1 for stirring can be stably operated even near the wall surface of the container 40.

  Next, other forms of the stirring rotor 1 will be described. 5A and 5B are front views showing examples of other forms of the flow passage 16. FIG. 2A shows an example in which the flow passage 16 is configured as a smoothly curved passage. By configuring the flow passage 16 in this way, the flow resistance in the flow passage 16 can be reduced, so that the flow caused by the stirring rotor 1 can be further strengthened and the stirring ability can be improved. In addition, such a flow path 16 can be formed by manufacturing the main body 10 by casting, for example.

  FIG. 2B shows an example in which the flow passage 16 is configured in a straight line. Even when the flow passage 16 is configured in this manner, the flow resistance in the flow passage 16 can be reduced. Furthermore, in this case, it is possible to facilitate cleaning of the flow passage 16.

  FIGS. 6A to 6C are diagrams showing examples of other forms of the suction port 12, the discharge port 14, and the flow passage 16. 1A is a plan view of the stirring rotator 1, and FIGS. 1B and 1C are front views of the stirring rotator 1. FIG.

  FIG. 4A shows an example in which the discharge port 14 is arranged so as to be shifted in the rotation direction, and the portion of the flow passage 16 connected to the discharge port 14 is angled with respect to the radial direction of the stirring rotating body 1. Show. In this way, by changing the direction of the discharge port 14, for example, when the stirring rotator 1 is rotated counterclockwise in the figure, the jet flow from the discharge port 14 can be made smooth. Further, when the stirring rotator 1 is rotated in the clockwise direction in the figure, the jet flow from the discharge port 14 can be in a turbulent state. In other words, in the present embodiment, by appropriately setting the arrangement and direction of the flow passage 16 and the discharge port 14 according to the application, it is possible to obtain a flow most suitable for efficient stirring. .

  FIG. 2B shows an example in which the discharge port 14 is arranged so as to be shifted in the direction of the rotation axis so that the portion connected to the discharge port 14 of the flow passage 16 faces the front end side of the rotating body 1 for stirring. . In this way, since the discharge port 14 is directed to the tip side, the flow in the liquid surface direction can be weakened, so that foaming caused by strong flow or turbulence near the liquid surface, mixing of bubbles, or the like is reduced. be able to. The discharge port 14 may be directed toward the drive shaft so that an external gas is entrained in the fluid.

  FIG. 2C shows an example in which one suction port 12 is provided for a plurality of discharge ports 14 and the flow passage 16 is branched from one suction port 12 to a plurality of discharge ports 14. . In this way, a common suction port 12 may be provided for the plurality of discharge ports 14. In this case, by making the cross-sectional area of the common portion 16a of the flow passage 16 the same or substantially the same as the sum of the cross-sectional areas of the branch portions 16b, the flow velocity in the common portion 16a can be prevented from being lowered. Thereby, it is possible to prevent accumulation of accumulated substances in the flow passage 16.

FIGS. 7A and 7B and FIGS. 8A and 8B are front views showing examples of other shapes of the main body 10. FIG. 7A shows an example in which the main body 10 is configured in a spherical shape, and FIG. 7B shows an example in which the main body 10 is configured in an ellipsoidal shape. The main body 10 may have any shape (for example, a columnar shape, a disk shape, or the like) as long as the cross section perpendicular to the rotation axis direction is formed in a circular shape. In order to make the flow accompanying the jet flow from the discharge port 14 smoothly, as shown in FIG. 7 (a) or (b), the shape in which the thickness in the rotation axis direction gradually decreases outward in the radial direction. preferable. In particular, as shown in FIG. 7 (b), the flow radially spreading from the stirring rotating body 1 can be made stronger by reducing the thickness in the rotational axis direction as a whole.

  In addition, the spherical shape in this invention has shown the wide concept including the shape which consists of a part of sphere, and the shape similar to a sphere. In addition, the ellipsoidal shape in the present invention indicates a broad concept including a shape composed of a part of the ellipsoid and a shape similar to the ellipsoid.

  FIG. 8A shows an example in which the main body 10 is configured in a shape in which the thickness in the rotation axis direction gradually decreases in a concave shape toward the outer side in the radial direction. By adopting such a shape, a part of the flow toward the suction port 12 and the flow from the rotating shaft side are caused to flow smoothly along the surface of the main body 10 to be an accompanying flow of the jet from the discharge port 14. Therefore, it becomes possible to generate a stronger flow.

  FIG. 8B shows an example in which the main body 10 is configured in a shape in which the thickness in the direction of the rotation axis partially decreases toward the outside in the radial direction. In this case, as shown in FIG. 8B, a portion where the thickness decreases may be provided on the radially outer side of the portion having a constant thickness, or the thickness may be provided on the radially outer side of the portion where the thickness decreases. A certain portion may be provided.

  In addition to the setting of the shape of the main body 10, the flow around the rotating body 1 for stirring can be further improved by appropriately setting the roughness of the surface of the main body 10, or by applying an appropriate uneven shape or dimple processing. You may make it control precisely. In addition, for example, an apple or a soccer ball may be colored on the surface of the main body 10 configured in a spherical shape to improve the design.

  FIG. 9A is a front view showing an example in which the suction port 12 is provided on the drive shaft side. The figure shows an example in which two of the four suction ports 12 are provided on the bottom surface 10a on the drive shaft side. As described above, the suction port 12 may be configured such that a part of the plurality of suction ports 12 is disposed on the distal end side and the remaining part is disposed on the drive shaft side. Further, depending on the application, all of the suction ports 12 may be provided on the drive shaft side.

  By appropriately setting the arrangement of the suction port 12, it is possible to generate an optimal flow according to the application. Further, if the suction port 12 on the drive shaft side is brought close to the liquid surface of the fluid to suck the gas outside the fluid, the outside gas can be actively taken into the fluid. Thereby, gas can be dissolved in the fluid or bubbles can be mixed in the fluid.

  FIG. 9B is a front view showing an example in which the agitation rotator 1 is provided with an intake port 13 for sucking a gas outside the fluid, and an air passage 17 connecting the intake port 13 and the discharge port 14. . In the figure, two intake ports 13 are provided on the surface of the drive shaft side of the main body 10 configured in a spherical shape, and an air passage 13 that connects the intake port 13 and the discharge port 14 via the flow passage 16 is formed inside the main body 10. An example is shown. As described above, the air inlet 13 and the air passage 17 are provided in the main body 10, and the stirring rotor 1 is rotated in a state where the air inlet 13 is exposed to the outside of the fluid, so that the gas can be easily dissolved in the fluid. , Bubbles can be mixed in the fluid.

  In this case, by disposing the intake port 13 radially inward (rotating shaft side) with respect to the intake port 12, the outflow of fluid from the intake port 13 is prevented, and gas is efficiently taken into the fluid. It becomes possible. Instead of connecting the vent path 17 to the discharge port 14 for ejecting fluid, a dedicated discharge port for ejecting gas into the fluid is provided separately, and the vent path 17 is connected to this dedicated discharge port. Good.

  FIGS. 10A and 10B are front views showing an example in which the stirring rotator 1 is configured to be able to capture foreign matter. FIG. 4A shows an example in which a filter 60 for capturing foreign matter such as dust is provided in the vicinity of the discharge port 14 of the flow passage 16. Thus, by providing the filter 60 in the middle of the flow passage 16, it is possible to remove foreign substances contained in the fluid simultaneously with stirring. The filter 60 may be made of a material according to the application, such as a wire mesh or sponge. Note that the position where the filter 60 is disposed is not limited to the position shown in FIG.

  FIG. 5B shows an example in which a recess 62 for capturing foreign matter is provided on the inner peripheral wall of the common portion 16a of the flow passage 16 when one suction port 12 is provided. When the number of the suction ports 12 is one, the fluid passing through the common portion 16 a of the flow passage 16 becomes a swirling flow by the rotation of the stirring rotating body 1. Therefore, by providing the concave portion 62 on the inner peripheral wall of the common portion 16a of the flow passage 16, foreign matters in the fluid can be captured in the concave portion 62 by the same principle as the centrifugal separation. A filter 60 may be provided in the recess 62 so that the trapped foreign matter is securely held in the recess 62.

  Next, a stirring device 2 configured by connecting a plurality of stirring rotors 1 will be described. FIGS. 11A and 11B are front views showing an example of the stirring device 2. The figure (a) has shown the example which connected the rotating body 1 for three stirring via the drive shaft, and the figure (b) has shown the example which connected the rotating body 1 for two stirring integrally. Show. As described above, the stirring ability can be further improved by connecting the plurality of stirring rotating bodies 1 in the direction of the rotation axis. This is particularly effective when the fluid to be stirred is deep. Further, in the example shown in FIG. 4B, if the gas outside the fluid is sucked from the suction port 14 on the drive shaft side, the gas can be taken into the fluid more efficiently.

  Moreover, it is possible to make the stirring apparatus 2 into a shape with higher designability by connecting the some rotating body 1 for stirring. For example, the merchantability as a home whisk can be enhanced by coloring the stirring device 2 shown in FIG.

As described above, the stirring rotator 1 according to this embodiment includes the main body 10 having a circular cross section perpendicular to the rotation axis direction , the suction port 12 provided on the surface of the main body 10, and the main body 10. The discharge port 14 is provided on the outer surface in the radial direction from the suction port 12, and the flow path connecting the suction port 12 and the discharge port 14 is provided.

For this reason, the rotating body 1 for stirring which has sufficient stirring capability can be manufactured at a much lower cost than an impeller or the like. Further, the cross section perpendicular to the rotation axis direction is formed into a circular shape, so that the reaction at the start of the rotation is eliminated and the container 40 or the rotating body for stirring is also used when hitting the container 40 containing the object to be stirred 50 or the like. 1 can be made less likely to be damaged or scraped. As a result, it is possible to perform safe and efficient stirring regardless of the application.

In addition, since the cross section perpendicular to the rotation axis direction of the main body 10 is formed in a circular shape, the occurrence of unbalance with respect to the rotation axis can be reduced. For this reason, unlike an impeller or the like that tends to cause unbalance, vibrations and whirling during rotation can be substantially eliminated.

  Further, the main body 10 is configured in a shape in which the thickness in the rotation axis direction gradually decreases toward the outer side in the radial direction. For this reason, the flow in the vicinity of the surface of the main body 10 can be smoothly made an accompanying flow of the jet from the discharge port 14. Thereby, since it becomes possible to generate a stronger flow, the stirring ability can be further improved.

  Moreover, the main body 10 is configured in a cylindrical shape or a disk shape in which at least one bottom surface is spherical. For this reason, while being able to generate a strong flow, for example, the suction port 12 can be brought close to a narrow portion such as a corner portion of a container, and the accumulated matter can be sucked. That is, it is possible to sufficiently stir all the corners of the container. The main body 10 may be configured in a spherical shape or an ellipsoidal shape.

  Further, a plurality of discharge ports 14 are provided, and the suction port 12 and the flow passage 16 are individually provided for each of the plurality of discharge ports 14. For this reason, the flow velocity in the flow path 16 can be maintained at an appropriate high speed. Thereby, it is possible to prevent the accumulated matter from accumulating in the flow passage 16 and the stirring ability from being lowered.

  The suction port 12 is provided on the opposite side of the drive shaft 20 connected to the main body 10 for rotating the main body 10. As a result, the accumulated matter at the bottom of the container 40 can be sucked up, so that uniform stirring without unevenness can be performed. Further, stirring can be performed without disturbing the liquid level of the object to be stirred 50.

  The suction port 12 is provided on the outer side in the radial direction of the rotation shaft (center axis C). For this reason, even when the stirring rotator 1 is brought close to the wall surface of the container 40, it is possible to avoid a situation in which the stirring rotator 1 is attracted to the wall surface and the suction port is blocked. Thereby, stable stirring can be performed even when the rotating body 1 for stirring is manually operated.

  In addition, the stirring rotator 1 may further include an intake port 13 for sucking a gas outside the object to be stirred, and an air passage 17 connecting the intake port 13 and the discharge port 14. In this way, bubbles can be easily mixed into the object to be stirred 40.

  Further, the stirring device 2 according to the present embodiment is configured by arranging a plurality of stirring rotating bodies 1 in the rotation axis direction. For this reason, while being able to improve stirring ability further, the designability can be improved.

  In the present embodiment, the example in which the thickness of the main body 10 is gradually decreased toward the outer side in the radial direction has been described, but the present invention is not limited to this.
