The upper limit water level detector 3 is arranged at a position close to the top of the sewage tank 2, and the lower limit water level detector 4 is arranged at a position at the bottom of the sewage tank 2. One end of the first drain pipe 17 is connected to the sewage tank 2, so that the sewage in the sewage tank 2 can be discharged out of the sewage tank 2 through the first drain pipe 17. The other end of the first drain pipe 17 is connected to the third drain pipe 20, so that the sewage in the sewage tank 2 can be discharged to the next process through the third drain pipe 20 for treatment. One end of the second drain pipe 18 is connected to the sewage tank 2, and the other end of the second drain pipe 18 is connected to the third drain pipe 20. The first valve 5, the second valve 6, the first filter 7, the first water pump 8 and the third valve 9 are installed on the first drain pipe 17 in sequence. The fourth valve 10, the fifth valve 11, the second filter 12, the second water pump 13 and the sixth valve 14 are installed on the second drain pipe 18 in sequence. The flow meter 16 is installed on the third drain pipe 20, which can detect whether the sewage in the sewage tank 2 is discharged to the next process.
[0016] The first valve 5 and the fourth valve 10 are manual valves, the second valve 6 , the third valve 9 , the fifth valve 11 and the sixth valve 14 are butterfly valves, and a pressure gauge 15 is also provided on the third drain pipe 20 .
[0017] The specific workflow is as follows:
[0018] As shown in Figure (2), the switch of the upper limit water level detector 3 is SQ1, the switch of the lower limit water level detector 4 is SQ2, SA1 and SA3 are manual start-up conversion switches, SA2 is a mute switch, SA2 is normally closed, when SA2 is disconnected, the buzzer 21 stops beeping, SB2 and SB3 are reset switches, SB4 is a flow switch, KM1 is the first water pump 8, KM5 is the second water pump 13, KM8 is the second valve 6, KM9 is the is the third valve 9, KM10 is the fifth valve 11, KM11 is the sixth valve 14, the first valve 5 and the fourth valve 10 are normally open valves. When the sewage discharge system operates normally and there is no blockage, the sewage enters the sewage tank 2 through the water inlet pipe 1, and the water level in the sewage tank 2 continues to rise. When it rises to the upper limit water level detector 3, SQ1 is triggered to close, KM1 is energized, the normally open contact of SKM1 is closed and energized, the first water pump 8 starts to pump water, and the sewage passes through the first valve 5, the second valve 6, the first filter 7, the first water pump 8 and the third valve 9 on the first drain pipe 17, flows into the third drain pipe 20, and passes through the flow meter 16 to be discharged from the sewage tank 2. As long as the first drain pipe 17 is not blocked, the sewage will be continuously drained through the first drain pipe 17. The second water pump 13 is not energized, and the sewage will not be drained through the second drain pipe 18.
[0019] When the sewage discharge system is blocked, the sewage cannot flow into the third drainage pipe 20 through the first drainage pipe 17, the flow meter 16 has insufficient flow or does not detect the sewage flow, triggering the flow switch SB4 to close, KT1 to be energized, the delay switch SKT1 to close, KM3 to be energized, the normally open contact of SKM3 to close, KM13 to be energized, the normally open contact of SKM13 to close, KM6 to be energized, the indicator light 19 to light up, the normally open contact of SKM6 to close, the buzzer 21 to sound an alarm, indicating that the first drainage pipe 17 is blocked and needs to be repaired, the normally closed contact of SKM6 to open, KM1 to lose power, and the first water pump 8 to stop pumping water. Because the first water pump 8 stops pumping water, the water level in the sewage tank 2 rises. When it rises to the upper limit water level detector 3, SQ1 is triggered to close. At this time, KM5 is energized, the second water pump 13 starts to pump water, the normally open contact of SKM5 is closed and energized, and the sewage flows into the third drain pipe 20 through the fourth valve 10, the fifth valve 11, the second filter 12, the second water pump 13 and the sixth valve 14 on the second drain pipe 18, and is discharged from the sewage tank 2 through the flow meter 16. The spare second drain pipe 18 starts to work to prevent the sewage in the sewage tank 2 from being discharged during the maintenance of the first drain pipe 17; when the maintenance of the first drain pipe 17 is completed, the maintenance personnel trigger the reset switch SB2, KM6 loses power, the indicator light goes out, the normally open contact of SKM6 opens, the buzzer 21 stops alarming, the second water pump 13 stops pumping water, the second drain pipe 18 stops draining, and the first drain pipe 17 resumes draining.
[0020] When the second drain pipe 18 is blocked, the sewage cannot flow into the third drain pipe 20 through the second drain pipe 18, the flow meter 16 has insufficient flow or does not detect the sewage flow, triggering the flow switch SB4 to close, KT1 to be energized, the delay switch SKT1 to close, KM4 to be energized, the normally open contact of SKM4 to close, KM13 to be energized, the normally open contact of SKM13 to close, KM7 to be energized, the indicator light 19 to light up, the normally open contact of SKM7 to close, and the buzzer 21 to sound an alarm, indicating that the second drain pipe 18 is blocked and needs maintenance. After the maintenance personnel trigger the reset switch SB3, KM7 loses power, the indicator light goes out, SKM7 turns on, and the buzzer 21 stops alarming.
[0021] According to the above process, when the first drain pipe 17 is blocked, the sewage discharge device alarms to prompt that the first drain pipe 17 is blocked, the first water pump 8 stops pumping water to prevent the first water pump 8 from pumping water empty and damaging the equipment, the second water pump 13 starts working, and the second drain pipe 18 starts to discharge sewage to prevent the sewage in the sewage tank 2 from overflowing during the maintenance of the first drain pipe 17.
[0022] To sum up, the sewage discharge device has a simple structure. Two drain pipes are connected outside the sewage tank. The other ends of the two drain pipes are connected to the third drain pipe. A flow meter is installed on the third drain pipe. The sewage is discharged through the first drain pipe and the third drain pipe. When the first drain pipe is blocked, the flow meter on the third drain pipe cannot detect the water flow, and an alarm is given. At the same time, the second drain pipe and the third drain pipe are started to discharge sewage, so that when the first drain pipe is blocked, an alarm can be given in time without affecting the normal discharge of sewage.
