Detect the water level in the tank and operate the submersible pump,
Pump and discharge through drain. The basic performance required of such a human waste crushing and pumping device is to ensure that when the submersible pump discharges sewage in the storage tank and stops, the remaining water in the storage tank is as small as possible, and that no residue such as solids remains. It is to keep the inside of the storage tank sanitary so that odor does not drift and insects and the like are not seen. Also, the number of times the submersible pump is operated is required to be as small as possible in order to suppress wear of the mechanical seal and the like.

ち上り、側面上部から外部に導かれている。The above-mentioned water level detection switch 4 detects an increase or decrease in the water level in the storage tank 2 and automatically operates the submersible pump 3. Miscellaneous drainage inlets 5 are provided at lower portions on both sides of the storage tank 2, and drainage from the remaining hot water in the bath, the washing surface, etc., flows in. A cylindrical screen 7 is mounted on the upper end of a vertical motor 6 fixed integrally with the submersible pump 3, and as shown in FIG. A cutter 8 is fixed coaxially with 3. Storage tank 2
The urine inlet 9 provided at the upper front of the screen 7 is connected to a drain port of a flush toilet (not shown), and communicates with the side surface of the screen 7. Further, the above submersible pump 3
The pumping drain pipe 10 connected to the discharge port of the container rises in the storage tank 2 and is guided to the outside from the upper side surface.

から下水道等に排出される。The human waste which flows from the flush toilet together with the carrier water of the low tank (both not shown) is passed through the human waste inlet 9 to the screen 7.
, And the carrier water passes through the screen 7 and falls into the storage tank 2 to raise the water level of the storage tank 2. When the water level rises above the water level described by the water level detection switch 4, the submersible pump 3 is operated to start discharging carrier water. At the same time, the human waste and toilet paper remaining in the screen 7 are crushed by the cutter 8, and when they are smaller than the mesh of the screen 7, they flow down into the storage tank 2 together with the transport water, and are pumped by the submersible pump 3 to drain the water.
The gray water drained from the drainage inlet 5 through the pump 10 is directly pumped by the submersible pump 3 to form the drainage pipe 10.
Is discharged to sewers.

あった。(Problems to be Solved by the Invention) However, in the above-described configuration, since the wastewater from the flush toilet flows together with about 10 transport waters at a time, the submersible pump 3 operates continuously. Since the wastewater flows continuously with a small amount of inflow, if the drainage capacity of the submersible pump 3 is large, the water level instantaneously drops below the detected water level and the operation of the submersible pump stops, but Since the water level continues, the water level rises immediately, the water level detection switch 4 operates, and the submersible pump 3 is operated, so that the operation is intermittent. Moreover, since the wastewater flowing from the wastewater inlet 5 hits the water level detection switch 4 directly or wraps around the submersible pump 3 and undulates, the water level detection switch 4 causes malfunction such as chattering, and the water discharge hammer phenomenon causes the pressure drainage pipe. This causes noise from the pump 10 and causes the mechanical seal of the submersible pump 3 and the bearings of the electric motor 6 to be worn out, resulting in a problem that the life of the submersible pump 3 is shortened. In addition, since the bottom in the storage tank 2 is flat and the water level detection switch 4 is disposed close to the submersible pump 3, sediment at the corner of the storage tank 2 stays as it is and accumulates, so that odor is generated. There were problems such as drifting and insects.

本発明は上記の問題を解決するもので、騒音のない衛
生的な屎尿破砕圧送装置を提供するものである。SUMMARY OF THE INVENTION The present invention solves the above-mentioned problems, and provides a sanitary human waste crushing and pumping apparatus without noise.

検知スイッチ４の作動回数も大幅に減少する。(Operation) With the above configuration, the operation of the water level detection switch is such that the submersible pump 3 and the water level detection switch 4 are installed separately, so that the change in the water flow when the submersible pump 3 operates is reduced. The installation of the elbow prevents miscellaneous drainage from directly hitting the water level detection switch 4, thereby preventing chattering and malfunction of the water level detection switch 4. Therefore,
There is no noise due to the water hammer phenomenon, and the number of actuations of the water level detection switch 4 is greatly reduced.

At the point where the outlet 11 is attached and the outlet flows in the opposite direction to the water level detection switch 4, and at the bottom of the storage tank 2, there is a kettle 2 a connected to the outlet of the elbow 11, the water level detection switch 4 and the submersible pump 3. This is the point that the height adjustable legs 12 are provided at the four corners of the bottom surface of the storage tank 2.

って流入する。The human waste that has flowed along with the transport water from the flush toilet (not shown) flows into the screen 7 through the human waste inlet 9, and the transport water passes through the eyes of the screen 7 and is located in the storage tank 2 a of the storage tank 2.
Accumulate in When the water level rises to the set water level of the water level detection switch 4, the submersible pump 3 starts operating and starts discharging the carrier water. Then, the water flows down to the kiln yard 2a and is conveyed by the submersible pump 3 through the pressurized drainage pipe 10. Further, the wastewater flowing from the wastewater inflow port 5 flows through the elbow 11 in a direction opposite to the position of the water level detection switch 4 and flows along the kiln yard 2a as indicated by an arrow A.

Further, the miscellaneous drainage that has been turned in the direction of the elbow 11 flows along the kiln 2a as shown by the arrow A,
Since the inflow speed is reduced and does not directly hit the water level detection switch 4, the water level detection switch 4 does not operate abnormally. When the water level reaches the set water level of the water level detection switch 4,
The submersible pump 3 starts operating, and the gray water is pumped and discharged through the pumping drain 10.

In addition, the number of actuations of the water level detection switch is greatly reduced, and the generation of noise due to the water hammer phenomenon is eliminated. Therefore, the wear of the mechanical seal of the submersible pump, the bearing for the electric motor, and the like can be suppressed, and the life of the submersible pump is prolonged.
