Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a drainage transfer device.
[0002]
[Prior art]
The soot generated in the kitchen is finely pulverized by a disposer, accompanied by water and transported as wastewater to a septic tank, and the transported wastewater is purified in the septic tank. Thus, FIG. 4 shows a conventional drainage transport apparatus for transporting drainage accompanied by crushed soot, in which 1 is a water supply device such as a faucet provided in the kitchen 2, and 3 is a kitchen 2. Disposer 5 disposed at the lower part of the pump and driven by the driving device 4, a pump equipped with a driving device for conveying the soot crushed and supplied by the disposer 3 together with water, 6 discharged from the pump 5 A transport pipe in which the soot is transported together with water, and 7 is a septic tank for treating the mixture of the soot and water transported from the transport pipe 6 using microorganisms.
[0003]
The transport pipe 6 extends slightly horizontally from the discharge side of the pump 5, rises and extends upward, and is disposed in a downward gradient from the uppermost portion toward the septic tank 7. Thus, the tip of the transport pipe 6 on the septic tank 7 side opens into the septic tank 7. The reason why the transport pipe 6 is disposed in a downward slope toward the septic tank 7 is to smoothly transport the soot contained in the drainage discharged from the pump 5 to the septic tank 7 using an inclination.
[0004]
In the figure, 8 is a controller that gives commands to the water supply device 1, the drive device 4 of the disposer 3, and the drive device of the pump 5.
[0005]
The soot generated by the processing of the food in the kitchen is thrown into the disposer 3 from the drain of the kitchen 2. In addition, a command is given from the controller 8 to the water supply device 1, the drive device 4 of the disposer 3, and the drive device of the pump 5, and each device is in an operating state. For this reason, in the disposer 3, the soot is pulverized and water from the water supply device 1 is supplied to the disposer 3 through the drain port of the kitchen 2, and the smashed soot is accompanied by the water and the pump 5 is discharged from the disposer 3. It is discharged to the transport pipe 6 and fed as waste water W from the transport pipe 6 to the septic tank 7.
[0006]
In the drainage transfer device, since there is a difference between the supply amount of the wastewater W including the soot crushed by the disposer 3 to the pump 5 and the discharge amount of the drainage W from the pump 5, an amount corresponding to the difference. The air is always mixed into the transport pipe 6. For this reason, as shown in FIG. 5, the drainage W becomes a laminar flow or a wave-like flow in the portion of the transport pipe 6 that is disposed at a slightly downward slope, and a layer of air A is formed in the upper part of the transport pipe 6. Is done.
[0007]
Accordingly, the pressure of water is not sufficiently transmitted to the pulverized solid matter M collected in the lower part of the transport pipe 6, and the solid matter M has a large specific gravity such as an egg shell or a shell. Is included, there is a problem that the solid M is difficult to flow and easily stays in the transport pipe 6.
[0008]
[Problems to be solved by the invention]
In view of the above-described circumstances, the present invention provides a drainage transport device that can reliably transport pulverized soot to a septic tank without stagnation in the transport pipe when transporting the pulverized soot from the disposer to the septic tank.

[0013]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
1 and 2 show an example of an embodiment of the present invention. In the figure, the same reference numerals as those in FIG. 4 denote the same components, and the basic configuration is the conventional configuration shown in FIG. It is the same as that.
[0014]
In FIG. 1, 10 is a compressor, 11 is an air tank for storing compressed air from the compressor 10, 12 is a conduit for supplying air A ′ from the air tank 11 to the base of the vertical portion of the transport pipe 6, 13. Is an electromagnetic valve provided in the middle of the pipe 12. In addition to the water supply device 1, the disposer 3 drive device 4, and the pump 5 drive device, the controller 8 can give a command to the electromagnetic valve 13.
[0015]
Next, the operation of the illustrated example will be described.
The soot generated by the processing of the food in the kitchen is thrown into the disposer 3 from the drain of the kitchen 2. Also, commands are given from the controller 8 to the water supply device 1, the drive device 4 of the disposer 3, and the drive device of the pump 5, so that each device is in an operating state, and commands are intermittently given to the electromagnetic valve 13. For this reason, the electromagnetic valve 13 is opened and closed at regular time intervals.
[0016]
In the disposer 3, the soot is pulverized, and water from the water supply device 1 is supplied to the disposer 3 through the drain port of the kitchen 2, and the smashed soot is accompanied by the water from the disposer 3 through the pump 5 to the transport pipe. 6 is discharged from the transfer pipe 6 to the septic tank 7 as waste water W.
[0017]
At this time, since the electromagnetic valve 13 is intermittently opened and closed at regular time intervals, the air A ′ compressed and generated by the compressor 10 and stored in the air tank 11 is intermittently transferred from the pipe 12 into the transport pipe 6. Supplied. For this reason, in the conveyance pipe 6, air A 'is supplied into the waste water W accompanied with soot, and the waste water W becomes a plug flow Pf as shown in FIG.
[0018]
Thus, when the waste water W becomes the plug flow Pf, the waste water W temporarily becomes full with respect to the transport pipe 6 as shown in FIG. Sufficient water pressure is applied. Therefore, the pulverized soot entrained in the waste water W is smoothly fed to the septic tank 7 by being smoothly fed through the transport pipe 6 without staying in the transport pipe 6.
[0019]
FIG. 3 shows a reference example of the present invention. In the figure, the same reference numerals as those in FIG. 4 denote the same parts, and the basic configuration is the same as the conventional one shown in FIG. .
[0020]
In the figure, reference numeral 14 denotes a check valve provided at a crossing portion of the rising portion and the inclined portion of the transport pipe 6, that is, at a position higher than the drainage discharge end position H of the transport pipe 6. Thus, outside air can flow into the transfer pipe 6 from the check valve 14, but the waste water W in the transfer pipe 6 does not flow out of the check valve 14 to the outside. In addition, what is necessary is just to provide the check valve 14 in the position higher than the water surface upper limit of the septic tank 7, when the waste_water | drain discharge | emission end part is always in the water of the septic tank 7. FIG. Further, a solenoid valve may be further connected to the check valve 14 so as to open and close the solenoid valve intermittently.
[0021]
In the illustrated example, when the soot crushed by the disposer 3 is transported through the transport pipe 6 together with water by the pump 5, outside air flows into the transport pipe 6 from the check valve 14. For this reason, as shown in FIG. 2, the waste water W becomes a plug flow Pf in the transport pipe 6. Accordingly, in this case as well, the waste water W temporarily becomes full with respect to the transport pipe 6 as shown in FIG. 2, and the solid matter M staying in the lower part of the transport pipe 6 has a sufficient water pressure. Join. Therefore, the pulverized soot entrained in the waste water W is smoothly fed to the septic tank 7 by being smoothly fed through the transport pipe 6 without staying in the transport pipe 6.
[0022]
In addition, the waste_water | drain conveyance apparatus of this invention is not limited only to the above-mentioned illustration example, Of course, a various change can be added in the range which does not deviate from the summary of this invention.
[0023]
【The invention's effect】
As described above, according to the drainage conveyance device according to claims 1 and 2 of the present invention, the pulverized soot entrained in the drainage can be smoothly fed into the conveyance pipe without staying in the conveyance pipe. It is possible to achieve an excellent effect of being reliably transported to the septic tank.
