Description

Downward sewage discharge system {PNEUMATIC SEWAGE DISCHARGING APPARATUS}

The present invention relates to a pneumatic sewage discharge device that quickly and smoothly discharges sewage using high-pressure compressed air when a predetermined amount or more of sewage is filled in the sewage tank. It relates to a pneumatic sewage discharge device that minimizes clogging and odors caused by foreign substances by stably discharging the sewage regardless of the load generated when discharging the sewage from the sewage tank.

In general, sewage generated from underground facilities of high-rise buildings such as apartment houses, buildings, or factories is primarily collected in a sewage tank provided in the underground space because natural drainage is difficult. The pump is driven by the on/off control according to the deviation signal of the change, pumped outdoors, and transferred to the forced drainage and sewage treatment plant.

However, there is a problem in that an unpleasant odor is generated when the waste water discharge time is longer than the capacity of the waste water tank in the process of forcibly draining the water using a pump.

In addition, according to the control signal of the water level control device, the pump or valve operates to maintain the water level in the sewage tank within a certain range, which detects the water level and transmits the change in water level as a deviation signal. When foreign substances are attached to the surface, malfunctions and malfunctions occur, which causes an overflow phenomenon in which sewage water overflows beyond a certain height in the sewage tank, causing the problem that the underground space is flooded.

In this regard, in Patent Document 1, when the sewage water reaches a certain level in the sewage tank, compressed air can be instantaneously introduced to discharge the sewage in a short time, and the sewage inlet pipe for introducing and discharging the sewage into the sewage tank A technology has been proposed to reduce the generation of odors during wastewater discharge work by submerging the lower part of the tank in the wastewater remaining in the wastewater tank.

However, since the discharge of sewage is performed by air pressure, a load due to air pressure is generated on the sewage inlet pipe in the process of discharging the sewage, which does not smoothly discharge the sewage, so that the diameter of the inflow pipe is maintained over a certain area. There are structural limitations such as what must be done.

First, the first and second sewage tanks 10 and 20 are supported by the first and second pedestals 61 and 71 in a state of being mounted on the first and second load sensors 60 and 70, and , by measuring the change in the mass of the sewage contained in the first and second sewage tanks 10 and 20 with the first and second load sensors 60 and 70 according to the change in the weight (storage amount), check in real time. This can prevent malfunctions or malfunctions from occurring.

That is, the sewage flowing into the sewage inlet distribution pipe 30 is naturally distributed through the first and second inlet pipes 11 and 21 to the first and second check valves 31 and 32 to the first and second It flows into the first and second waste water tanks 10 and 20 respectively through the second gate valves 33 and 34, etc., and in this process, when either one reaches a predetermined high water level, the first and second loads By operating the first and second cross valves 13 and 23 by the interlocking operation of the first and second electromagnetic valves 15 and 25 according to the measurement of the sensors 60 and 70, the sewage can be discharged alternately. can

For example, when the weight measurement values of the first and second waste water tanks 10 and 20 of the first and second load sensors 60 and 70 do not fall within the normal range, the control unit controls the first and second electromagnetic valves 15 ) (25) to operate the first and second cross valves (13, 23) and the first and second discharge valves (18, 28), and at the same time, the first and second sewage tanks (10) By supplying the compressed air of the air receiver 50 to the inside of the 20, the sewage contained in the first and second sewage tanks 10 and 20 is removed with the first and second discharge valves 18 and 28.

It flows into the second sewage tank 20, and in this process, the second solenoid valve 25 is not operated even if the second sewage tank 20 is also filled with sewage and reaches a predetermined high water level (storage amount), and then the first load sensor When the 60 detects the low water level (storage amount) of the first sewage tank 10 and the first cross valve 13 is in the closed state, the second cross valve 23 is controlled to the open state.

Conversely, when the first sewage tank 10 is filled with sewage water and reaches a predetermined high water level (storage amount), the first electromagnetic valve 15 is not operated alternately, and the second load sensor 70 turns on the second sewage water. When the second cross valve 23 is closed by sensing the low water level (storage amount) in the tank 20 , the first cross valve 13 is controlled to the open state.

In addition, when the sewage in the first and second sewage tanks 10 and 20 is at a low water level, the first and second load sensors 60 and 70 and the first and second solenoid valves 15 and 25 work together. By operating the first and second cross valves 13 and 23 to stop the supply of air through the first air supply pipe 53 to the first and second ejectors 81 and 82, the first and second waste water The inflow of sewage back into the tanks 10 and 20 can be started.

On the other hand, as shown in FIG. 3 , the sewage discharge device according to another embodiment of the present invention discharges sewage to the outside using air pressure when any one of the two sewage tanks is filled with a predetermined water level, and in this process If the wastewater is continuously collected in the other one and filled to a predetermined water level, it can be treated alternately and continuously. 2 Sewage tank (20), second discharge valve (28), sewage inlet distribution pipe (30), sewage discharge joint pipe (40), air receiver (50), first load sensor (60), second load sensor ( 70), a first ejector 81 , a second ejector 82 , a first screw conveyor 91 and a second screw conveyor 92 .
