[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a relay pump tank provided with a pump for discharging wastewater to a wastewater treatment apparatus in a relay tank that receives wastewater from a drainage source such as a disposer in a kitchen or kitchen.
[0002]
[Prior art]
The present applicant has already proposed, for example, a wastewater treatment system for treating wastewater from a disposer attached to a sink sink in a wastewater treatment apparatus installed outdoors as shown in FIG. Application 2000-390286).
[0003]
As shown in the figure, a disposer 2 is attached to a drain outlet of an indoor sink 1, a water supply pipe 3 is connected to the disposer 2, and a water supply valve 4 is attached to the water supply pipe 3.
[0004]
The drain pipe 6 connected to the discharge port of the disposer 2 is formed with a U-shaped trap 6a for sealing water in the middle, and is piped to the relay tank 7 buried outdoors. The inlet 7a is formed in the upper part. In the relay tank 7, a pressure feed pump 8 and a float sensor 9 are provided, and a discharge pipe 10 connected to the discharge port of the pressure feed pump 8 passes through the upper cover 7 b of the relay tank 7 and is disposed on the ground. It is connected to the device 11.
[0005]
The wastewater treatment device 11 includes, for example, a miscellaneous wastewater flow rate adjustment tank into which domestic wastewater used in a kitchen other than when the disposer is used flows via a flow path switching device to which the discharge pipe 10 from the pressure pump 8 is connected, Wastewater containing pulverized garbage when using the disposer that flows in through the flow path switching device, garbage flow rate adjustment tank into which sludge returned by an air lift pump flows from a coagulation sedimentation tank described later, and this garbage flow rate adjustment A solid-liquid separation device that separates a solid-liquid mixture transferred from the tank by an air lift pump into a solid component and a liquid component, and a liquid component separated by the solid-liquid separation device is charged and an air lift from the miscellaneous drainage flow rate adjustment tank A carrier fluid tank (aeration tank) into which domestic wastewater transferred by the pump is introduced, and sludge in the treated water flowing in from the carrier fluid tank by natural flow are aggregated and settled. A composting apparatus for composting with microorganisms living in the carrier by stirring and mixing the aggregating sedimentation tank to be separated, the solid component separated and input by the solid-liquid separator and the microbial carrier stored in advance with a stirring body Etc.
[0006]
The sludge precipitated and separated in the coagulation sedimentation tank is returned to the garbage flow rate adjustment tank by an air lift pump. Discharged. A sewage pipe 14 is connected to the sewage basin 12, and treated water discharged from the waste water treatment device 11 is discharged to the sewage pipe 14 through the sewage basin 12.
[0007]
The side wall of the relay tank 7 is positioned lower than the inflow port 7a for drainage from the disposer 2 and higher than the maximum water level of the relay tank 7 during normal operation of the pressure pump 8 and the float sensor 9. A discharge port 7c is formed, and a pipe 15 connected to the discharge port 7c is connected to the sewage drain 12 with a slight downward slope.
[0008]
Further, the discharge port 14a of the sewage pipe 14 provided in the sewage basin 12 is formed so as to be bent downward and continuously submerged, so that a sealed trap 14b is provided. It is designed to prevent odors and pests from entering.
[0009]
The disposer drain pipe 6 or the discharge pipe 10 is attached with, for example, a capacitance type flow rate detection sensor 6b or 10b. The upper lid 7b of the relay tank 7 is provided with an air vent 71 that is provided with measures against rain.
[0010]
In the above configuration, during normal operation of the pressure pump 8 and the float sensor 9, waste water containing pulverized garbage that has been crushed by the disposer 2 and normal domestic waste water generated in the kitchen flow into the relay tank 7 through the drain pipe 6. When the water level in the relay tank 7 becomes a certain level or more, the float sensor 9 is turned on and the pumping pump 8 is driven. The waste water pumped by the pressure pump 8 is conveyed to the waste water treatment device 11 through the discharge pipe 10. In the wastewater treatment device 11, the flow path switching device described above is on the side of the miscellaneous wastewater flow rate adjustment tank except when the disposer is used, and is switched to the garbage flow rate adjustment tank side only when the disposer is used. The waste water containing the crushed garbage flows into the garbage flow rate adjustment tank. The treated water purified by the waste water treatment device 11 naturally flows down to the sewage water 12 through the pipe 13 and flows into the sewage pipe 14.
[0011]
On the other hand, if the conveyance capacity of the pressure pump 8 becomes insufficient or does not function due to a failure of the pressure pump 8, a power failure, or a malfunction of the float sensor 9, the water level in the relay tank 7 is set to the highest water level when normal. Although it rises exceeding, when it rises to the position of the discharge port 7c formed in the side wall, it flows out from the discharge port 7c to the discharge tank 12 through the pipe 15 by natural flow and flows into the sewer pipe 14.
[0012]
[Problems to be solved by the invention]
By the way, in the relay pump tank, as the relay tank 7, a solid tank such as pulverized garbage is likely to accumulate and remain, and has a bottom shape that is unsuitable for the relay pump tank, but is an inexpensive ready-made tank ( As shown in FIG. 9, the partition plate 7e is attached to the inner periphery of the bottom of the relay tank 7 in a substantially mortar shape, and the legs of the pump 8 are attached to the bottom of the tank surrounded by the partition plate 7e. 81 is installed.
[0013]
However, in such a configuration, when the pump 8 is removed from the state of FIG. 9 as shown in FIG. 10 due to a failure of the pump 8 or the like, solid matter such as pulverized garbage remaining on the side slope of the partition plate 7e. Since S falls to the bottom of the tank where the legs 81 of the pump 8 are installed and the pump 8 is re-installed, the solid matter S such as pulverized garbage is sandwiched under the legs 81 of the pump 8. 8 cannot be easily installed at a predetermined position. Since the relay tank 7 is buried in the ground, it cannot be turned upside down, and the solid matter S such as crushed garbage on the bottom of the tank must be removed manually, which is not easy.
[0014]
Further, in constructing the relay pump tank using a ready-made tank which is inexpensive in cost, the pump 8 can be installed as described above, and the solid matter S such as pulverized garbage from the disposer 2 The partition plate 7e is attached in the shape of a mortar so that it can be guided to the vicinity of the suction port 82 and smoothly pumped out. However, since the back side of the partition plate 7e is a gap, water pressure is always applied to the partition plate 7e. Is in a state.
[0015]
On the other hand, when the pump 8 is driven, a force is generated to rotate the pump main body in the direction opposite to the motor rotation direction of the pump 8, and the force 81 is received by the leg 81 of the pump 8 being fitted. This is a partition plate 7e. However, if the structure is as described above, the partition plate 7e may be broken. If it is broken, the pump 8 cannot be fixed, and an intermittent overload or the like is generated on the discharge pipe 10. Cause breakage.
[0016]
In addition, the ground garbage wastewater enters from the gap between the broken partition plate 7e and the relay tank 7, and the ground garbage accumulates, so that the range of the treatment capacity of the wastewater treatment device 11 due to anaerobic or the like in the relay tank 7 There is also a possibility that the processing performance of the waste water treatment device 11 may be deteriorated due to the generation of waste ground garbage waste.
[0017]
Accordingly, the present invention has been made to solve such problems, and it is intended to provide a relay pump tank that can easily re-install the pump at a predetermined position even when the pump is detached or attached due to a failure or the like. It is the purpose.
[0018]
Furthermore, it is an object of the present invention to provide a relay pump tank that can prevent the occurrence of the above-mentioned problems even if an off-the-shelf tank that is inexpensive is used.
[0019]
[Means for Solving the Problems]
In order to achieve the above object, the present invention provides a relay pump tank equipped with a pump for discharging wastewater to a wastewater treatment device in a relay tank that receives wastewater from a drainage source, and at the bottom of the relay tank. A leg installation portion on which the pump legs are installed and a deep portion formed deeper than the leg installation portion are provided.
[0020]
Furthermore, an inclined path is formed between the leg installation part and the deep part.
[0021]
The deep portion is located below the suction port of the pump.
[0022]
In addition, a pump detent member having a groove into which a rib formed on the inner surface of the relay tank is fitted on the outer peripheral side, the inner peripheral side forming a substantially mortar shape, and the leg installation portion and the deep portion are formed. It is characterized by that.
[0023]
Further, the pump detent member is a hollow molded article in which an inlet for injecting water or the like is formed.
[0024]

[0025]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, an embodiment of the present invention will be described in detail with reference to FIGS. 8 to 10 indicate the same or corresponding parts.
[0026]
In the relay pump tank of this embodiment, a pressure feed pump 8 is installed at the bottom of the relay tank 7 composed of two upper and lower parts via a pump detent member 70 described below, and a float sensor 9 is attached to the pressure feed pump 8. Yes.
[0027]
The relay tank 7 uses an inexpensive ready-made tank used as rainwater trough, etc., and its lower inner surface is provided with reinforcement as shown in FIG. Three vertical ribs 7d are formed in advance at equal intervals.
[0028]
On the other hand, the pump detent member 70 has a substantially mortar shape on the inner surface, and the bottom side thereof corresponds to the three legs 81 of the pumping pump 8 as shown in FIG. And a deep portion 70b that is formed deeper than these leg placement portions 70a and is located directly below the suction port 82 of the pumping pump 8. The leg placement portions 70a and the deep portions are provided. A slope-like guide path 70c is formed between the two and 70b. Further, on the outer periphery of the pump detent member 70, a groove 70d into which the rib 7d is fitted in correspondence with the three longitudinal ribs 7d previously formed in the ready-made tank used for the relay tank 7. Is formed.
[0029]
This pump detent member 70 is a hollow molded product by blow molding or the like, and is molded so that the inside becomes one space. An inlet 70e for injecting tap water and the like and a cap for closing it 70f.
[0030]
On the other hand, a drain pipe 6 from the disposer 2 shown in FIG. 8 is piped on the upper side wall of the relay tank 7 to form a downward inflow port 7a and to the sewage trough 12 shown in FIG. An overflow pipe 15 is attached to form an overflow outlet 7c.
[0031]
Further, although not shown in the figure, the air vent 71a provided with measures against rain as shown in FIGS. 8 to 10 and the L-shaped joint pipe 72 for the discharge pipe 10 are engaged with the upper lid 7b of the relay tank 7. A convex portion 71b to be supported is formed, and a gourd-shaped cord threading and peeping hole 73 connected with large and small holes is formed near the center.
[0032]
A fitting portion 74 a formed on the back side of the cord threading / penetrating lid 74 having a size covering the hole 73 is fitted into the cord threading / peering hole 73. The cord threading / penetrating lid 74 is made of a flexible material such as synthetic rubber and excellent in weather resistance (ultraviolet rays, temperature, rain, etc.). Since the cover 74 is formed of a flexible material, a step-out prevention rib 73a is integrally formed with the upper cover 7b so that the cover 74 is positioned directly below the cover 74 when the cover 74 is attached to the cord passage / penetration hole 73. , Even if it is stepped on, it is configured not to cause problems such as stepping out.
[0033]
As shown in FIGS. 3A and 3B, the cord threading / penetrating lid 74 includes a base portion 74b positioned on the small hole side of the cord threading / penetrating hole 73 and a base portion 74b positioned on the large hole side. And a peep lid portion 74d connected to each other through a thinly bent portion 74c.
[0034]
The small-diameter base 74b is formed with two cord passage holes 74e and 74f through which the pump power cord 8a and the float sensor cord 9a are passed, and further, a notch 74g is formed to reach each cord passage hole 74e and 74f. Yes. By forming such a notch 74g, it is only necessary to open the notch 74g and set the cords 8a and 9a in the corresponding cord passage holes 74e and 74f as shown in FIG. Becomes easier.
[0035]
Further, a plurality of cord waterproof ribs 74h are provided inside the cord passage holes 74e and 74f on the outer periphery of the fitting portion 74a of the cord passage / penetration lid 74 which becomes a contact surface with the cord passage / penetration hole 73. A plurality of waterproof ribs 74i are formed. At the lower end, a retaining claw 74j is formed so that it is difficult to remove when the cord threading / penetrating lid 74 is fitted into the cord threading / groove hole 73. Further, a handle 74k is formed on the upper surface side of the viewing lid portion 74d.
[0036]
As described above, the power cord 8a for the pump and the cord 9a for the float sensor are passed through the cord passage holes 74e and 74f formed in the base portion 74b of the cord passage / penetration lid 74 through the cut 74g. , 9a is inserted into the small hole side of the cord threading / penetrating hole 73, and the notch 74g is firmly closed and pressed against the cords 8a, 9a, so that the cords 8a, 9a are displaced and the relay tank 7 is not slackened and does not adversely affect the flowability of the ground garbage wastewater from the disposer drain pipe 6.
[0037]
Further, since the waterproof rib 74i is formed on the outer periphery of the fitting portion 74a of the cord threading / penetrating lid 74, rainwater or the like enters the relay tank 7 from the gap between the cord threading / peering lid 74 and the cord threading / peering hole 73. Can be prevented from entering. Similarly, since the cord waterproof ribs 74h are also formed inside the cord passage holes 74e and 74f, it is possible to prevent rainwater and the like from entering the relay tank 7 through the cord passage holes 74e and 74f. .
[0038]
Further, since a retaining claw 74j is formed at the lower end of the fitting portion 74a of the cord threading / penetrating lid 74, the cord threading / peering lid 74 is detached from the cord threading / peering hole 73 during normal use. Can be prevented.
[0039]
When visually checking the inside of the relay tank 7 for inspection, simply pull the handle 74k provided on the observation lid 74d of the cord threading / penetration lid 74 by hand, and without using a tool or the like, The peeping lid 74d is pulled up while the retaining claw 74j located immediately below is removed and bent at a bent portion 74c formed between the claw 74j and the base 74b.
[0040]
Thus, the state inside the relay tank 7 can be easily confirmed from the cord passage / peer hole 73 without removing the discharge pipe 10 or processing the cords 8a, 9a.
[0041]
In the above configuration, when the pressure pump 8 is installed in the relay tank 7 when the relay pump tank is installed, as shown in FIG. 4, first, tap water or the like is supplied from the inlet 70e of the pump detent member 70. Fill with water until it is full and plug with cap 70f.
[0042]
Next, the groove 70 d of the pump detent member 70 is aligned with the rib 7 d formed on the lower inner surface of the relay tank 7, and the pump detent member 70 is installed at the bottom of the relay tank 7. At this time, a filling adhesive such as silicon putty is poured into a slight gap generated between the relay tank 7 and the pump detent member 70. Thereafter, the pumping pump 8 is set so that the corresponding leg 81 of the pumping pump 8 is matched with each leg installation portion 70 a of the pump detent member 70.
[0043]
The relay pump tank assembled in this way has the following effects.
[0044]
That is, each leg 81 of the pressure feed pump 8 is fitted into the corresponding leg installation portion 70a of the pump detent member 70, and the rib 7d of the relay tank 7 is fitted into the groove 70d of the pump detent member 70. Even if a force that rotates the pump body is generated when the pump 8 is driven, the pump body does not move. Incidentally, the vertical direction of the pressure pump 8 is fixed to the upper lid 7b via the discharge pipe 10. If the pressure pump 8 is damaged and needs to be replaced, if the upper lid 7b is lifted, each leg 81 of the pressure pump 8 is only fitted into the foot installation part 70a. The pump 8 can be pulled up together, and the trouble at the time of pump replacement of the relay pump tank buried in the ground can be reduced.
[0045]
In addition, since the hollow pump detent member 70 is filled with tap water or the like, a filling adhesive such as silicon putty is not used between the relay tank 7 and the pump detent member 70. However, not only buoyancy does not occur, but also cancels out the water pressure due to the pulverized garbage wastewater staying in the relay tank 7. Moreover, since the inner surface is formed in a substantially mortar shape, solid matter such as pulverized garbage can be guided to the vicinity of the suction port 82 of the pressure pump 8 and pumped out smoothly.
[0046]
Further, as shown in FIGS. 8 to 10, the pulverized garbage drainage enters the inner space from the gap between the partition plate 7e and the relay tank 7, and the pulverized garbage is accumulated on the back side of the partition plate 7e. Is also not structurally possible.
[0047]
Further, if the pump detent member 70 is made entirely of resin by injection molding or the like, the material cost is considerably increased and the weight becomes heavy, but tap water is added to the hollow molded product by blow molding or the like as in this embodiment. By adopting a configuration in which the interior is filled with, etc., it is possible to manufacture at a low cost as well as weight reduction.
[0048]
When the pumping pump 8 is detached due to a failure or the like, if the pumping pump 8 is removed as shown in FIG. 5, the solid matter S such as pulverized garbage remaining on the side inclined surface of the pump detent member 70 is transferred to the leg installation part 70a. Falling. Even if it is going to reinstall pressure feed pump 8 in leg installation part 70a as it is, solid substance S, such as ground garbage, is pinched between leg 81 and leg installation part 70a of pressure feed pump 8, and pressure feed pump 8 is stabilized. I can't put it on.
[0049]
However, as shown in FIG. 6, when washing water is poured using a hose H or the like, the solid matter S in the leg installation part 70a smoothly gathers in the deep part 70b through the slope-shaped guide path 70c, and the leg installation part The solid matter S disappears in 70a. Therefore, since the solid substance S is not sandwiched between the leg 81 of the pressure pump 8 and the leg installation portion 70a when the pressure pump 8 is installed, it can be easily installed in a stable state.
[0050]
Further, as shown in FIG. 7, the deep part 70b where the solid matter S gathers is directly under the suction port 82 of the pumping pump 8, so when the re-installed pumping pump 8 is driven, it is quickly sucked from the suction port 82, It is discharged through the discharge pipe 10 to the waste water treatment apparatus 11 shown in FIG.
[0051]
As described above, according to this embodiment, a solid tank such as pulverized garbage is likely to accumulate and remain, and a ready-made tank having a bottom shape unsuitable for a relay pump tank is provided with various pumps. By using the stop member 70, as described above, it can be used as a relay pump tank in which crushed garbage is unlikely to accumulate and remain without causing problems, and cost can be reduced.
[0052]
In addition, when the drainage source is the disposer 2 attached to the sink 1 of the sink as in the present embodiment, a large amount of pulverized garbage is particularly effective.
[0053]
【The invention's effect】
As described above, according to the present invention, in a relay pump tank equipped with a pump for discharging wastewater to a wastewater treatment device in a relay tank that receives wastewater from a drainage source, a pump leg is installed at the bottom of the relay tank. When the pump is removed from the pump due to a malfunction, etc., the leg installation section and the deep section formed deeper than the leg installation section are provided. Even if the solid matter falls, it can be easily caused to flow down to the deep part with washing water or the like, so that the pump can be easily reinstalled at a predetermined position.
[0054]
Furthermore, by forming an inclined path between the leg installation part and the deep part, solid matter such as crushed garbage in the leg installation part can be smoothly flowed down to the deep part with washing water or the like.
[0055]
Moreover, since the said deep part is located under the suction inlet of the said pump, solid substances, such as the crushing garbage collected in the deep part, can be discharged | emitted rapidly.
[0056]
In addition, a pump detent member having a groove into which a rib formed on the inner surface of the relay tank is fitted on the outer peripheral side, the inner peripheral side forming a substantially mortar shape, and the leg installation portion and the deep portion are formed. In addition to the effects described above, the pump can be driven stably, and a solid tank such as crushed garbage is likely to accumulate and remain, and a ready-made tank having a bottom shape that is unsuitable as a relay tank pump tank. In addition, it can be used as a relay pump tank in which solid matter such as pulverized garbage is unlikely to accumulate and remain without problems, and cost reduction can be achieved.
[0057]
Furthermore, since the pump detent member is made of a hollow molded product in which an injection port for injecting water or the like is formed, it can be manufactured at a low cost as well as light weight.
[0058]
Further, when the drainage source is a disposer attached to a sink of a sink in a kitchen or kitchen, a large amount of pulverized garbage is particularly effective.
