[0002] Wastewater treatment equipment is an environmental protection device. In daily production and life, people generate a large amount of domestic sewage and industrial wastewater. The sewage contains various solid wastes, nutrient elements, artificial pigments and harmful bacteria, so the sewage must be treated and purified before it can be safely discharged.

[0003] However, most existing wastewater treatment plants lack automatic cleaning mechanisms. After prolonged operation, operators must manually clean the interior of the plant, reducing work efficiency and increasing the workload. Furthermore, existing plants lack sludge mixing capabilities, leading to sludge clumping after a period of settling. When the sludge clumps are large or highly viscous, they can easily clog the discharge outlet. In such cases, manual emergency treatment of the blockage is required before resuming operation, significantly reducing economic efficiency, wasting time and effort, and increasing the risk of safety accidents. Existing plants can only clean sludge clogs inside the plant, not those in the sludge discharge pipes. Summary of the Invention

[0034] The third water pipe 31 is a multi-pipe system. One end of the third water pipe 31 is connected to the first water pipe 411, and the other end is connected to the second water pipe 421. Three sets of pipes branch off from one side of the third water pipe 31 and are connected to three sets of sludge discharge pipes respectively.

[0035] The second sludge removal assembly 4 includes a first water tank 41, a first water pipe 411, a first flushing nozzle 412, a second water tank 42, a second water pipe 421, and a second flushing nozzle 422;

[0036] The first water tank 41 is located on the outside of the sludge discharge device 1. One end of the first water pipe 411 is connected to the first water tank 41, and the other end passes through the sludge discharge device 1 and is connected to the third water pipe 31. The first flushing nozzle 412 is fixedly installed on the inside of the sludge discharge device 1. The second water tank 42 is located on the outside of the sludge discharge device 1. One end of the second water pipe 421 is connected to the second water tank 42, and the other end passes through the sludge discharge device 1 and is connected to the third water pipe 31. The second flushing nozzle 422 is fixedly installed on the inside of the sludge discharge device 1. The first flushing nozzle 412 and the second flushing nozzle 422 are used to flush the sludge remaining on the two sets of stirring rods. Both sets of water tanks have built-in water pumps (not shown in the figure) to pressurize the water and pump it out. The first flushing nozzle 412 and the second flushing nozzle 422 have built-in valves (not shown in the figure) and are connected to the equipment program signal.

[0037] The sludge discharge device 1 is equipped with a program that can control the start and stop of three sets of motors, the opening and closing of three sets of electric valves, and the start and stop of two sets of water pumps built into the water tanks.

[0038] The sludge discharge device 1 is powered by an external power source to drive the internal device. The three sets of motors are powered by an external power source, and the second movable base 22 is moved by an external motor.

[0039] The external motor, two sets of motors, three sets of electric valves, two sets of built-in water pumps in the water tank, three sets of sludge discharge valves, two sets of built-in resistance detectors for the motors, and three sets of flow detection valves of the second moving base 22 are all connected to the equipment program signal.

[0040] Sludge discharge operation:

[0041] When staff need to clean the sludge in the sludge discharge device 1, they first turn on the external power supply. The sludge discharge device 1 starts, and the equipment program starts. The equipment program controls the opening of the first sludge discharge valve 14, the second sludge discharge valve 15, and the third sludge discharge valve 16. The first motor 23 and the second motor 24 start to operate, and the two sets of stirring rods start to run, stirring the sludge in the sludge discharge device 1 so that it can be quickly discharged from the three sets of sludge discharge pipes. At this time, the equipment program detects the flow value of the three sets of flow detection valves. The equipment program sets the flow value to M3, M2, and M1. The equipment program detects the flow of the three sets of flow detection valves and compares it with the set flow value. When the flow value is M3, the equipment program determines that the three sets of sludge discharge pipes can operate normally without blockage. At this time, the equipment program does not operate. When the equipment program detects the flow value is M2, the equipment program determines that the amount of sludge discharged has decreased and blockage has occurred. When the equipment program detects the flow value is M1, the equipment program determines that the sludge has blocked the three sets of sludge discharge pipes, and the sludge discharge device 1 cannot operate normally. The equipment program then controls the next operation.

[0042] By setting up three sets of sludge discharge pipes, the sludge discharge efficiency can be effectively improved. Even if one pipe is blocked, the other two pipes can still operate normally, ensuring the working efficiency of sludge discharge device 1. Through the coordinated use of three sets of flow detection valves and equipment programs, the sludge flow rate in the three sets of sludge discharge pipes can be detected. The blockage of the three sets of sludge discharge pipes can be detected based on the change in the sludge flow rate value, eliminating the need for manual inspection and effectively improving the factory's production efficiency. Through the coordinated use of two sets of motors, two sets of stirring rods, and equipment programs, the sludge in sludge discharge device 1 can be stirred, making it into a semi-fluid state, which can be discharged from the three sets of sludge discharge pipes more quickly, effectively improving the sludge discharge efficiency.

[0043] Sludge discharge testing procedures:

[0044] After the above sludge flow detection operation is completed, the equipment program detects the values ​​of the built-in resistance detectors of the two sets of motors. The equipment program sets the resistance values ​​to N1, N2, and N3. The equipment program detects the values ​​of the built-in resistance detectors of the two sets of motors and compares them with the set resistance values. When the flow rate is detected to be M3 and the resistance value is N1, the equipment program determines that the sludge discharge device 1 is not blocked and the equipment program does not operate.

[0045] When the detected flow rate is M1 or M2 and the resistance is N1, the equipment program determines that the sludge in the sludge discharge device 1 has not clumped or blocked, but the three sets of sludge discharge pipes are blocked. At this time, the equipment program controls the two sets of water tank built-in water pumps to start, the first electric valve 32, the second electric valve 33, and the third electric valve 34 to open, and the built-in valves of the first flushing nozzle 412 and the second flushing nozzle 422 to close. After being pressurized, the water flows into the first water pipe 411 and the second water pipe 421, and then into the third water pipe 31. Finally, it is sprayed out from the three sets of cleaning nozzles in the form of water jets to impact the sludge in the three sets of sludge discharge pipes, preventing the sludge from clumping or accumulating too much and blocking the three sets of sludge discharge pipes. The equipment program sets the spraying time to T1. When T1 time is up, the equipment program controls the two sets of water tank built-in water pumps, the first electric valve 32, the second electric valve 33, and the third electric valve 34 to close.

[0046] When the detected flow rate is M1 or M2 and the resistance value is N2, the equipment program determines that the sludge in the sludge discharge device 1 has clumped or has poor flowability, causing blockage. At this time, the equipment program controls the built-in valves of the first flushing nozzle 412 and the second flushing nozzle 422 to open, the three sets of electric valves to close, and the two sets of water tank built-in pumps to open. After being pressurized, the water flows out in the form of water jets from the first flushing nozzle 412 and the second flushing nozzle 422. At this time, the equipment program detects the resistance value. If the resistance value drops to N1, it controls the built-in valves of the first flushing nozzle 412 and the second flushing nozzle 422 and the two sets of water tank built-in pumps to close. At the same time, it detects whether the flow rate has changed to M3. If it has changed to M3, the equipment program does not operate. If it has not changed to M3, the equipment program controls the above-mentioned water spraying operation.

[0047] When the detected flow rate is M1 or M2 and the resistance value is N3, the equipment program determines that the sludge in the sludge discharge device 1 has clumped together and cannot be discharged normally. At this time, the equipment program repeats the above operation and controls the external motor of the second moving seat 22 to start. The equipment program controls the second moving seat 22 to reciprocate along the track of the first moving seat 21 to stir the sludge in all corners of the sludge discharge device 1, preventing the sludge from clumping and accumulating in the corners, which would lead to insufficient sludge discharge. At this time, the equipment program detects the resistance value. If the resistance value drops to N1, it controls the external motor of the second moving seat 22 to turn off. At the same time, it detects whether the flow rate has changed to M3. If it has changed to M3, the equipment program does not operate. If it has not changed to M3, the equipment program controls the above water spraying operation.

[0048] By using two sets of motor-built-in resistance detectors, three sets of flow detection valves, and the equipment program in conjunction with them, the stirring resistance of the two sets of stirring rods can be detected to determine whether the blockage is caused by sludge clumping in the sludge discharge device 1 or by sludge blockage in the three sets of sludge discharge pipes. High-pressure water jets are sprayed from three sets of cleaning nozzles to impact the sludge blockage in the three sets of sludge discharge pipes, allowing it to be discharged smoothly. At the same time, the three sets of sludge discharge pipes also perform a self-cleaning operation. By using two sets of flushing nozzles, two sets of stirring rods, and the equipment program in conjunction with them, the sludge clumping at the bottom of the sludge discharge device 1 can be mixed with water and discharged. The reciprocating motion of the two sets of stirring rods can clean the sludge clumping in the corners, ensuring the sludge discharge efficiency of the sludge discharge device 1 and preventing incomplete sludge discharge due to corner blockages. This makes the sludge discharge device 1 more comprehensive in function. While cleaning the sludge in the sludge discharge device 1, the sludge in the three sets of sludge discharge pipes can also be self-cleaned, ensuring that the sludge discharge device 1 can operate normally and improving the factory's production efficiency.

[0049] Self-cleaning operation:

[0050] When the above operations are completed, the staff controls the equipment program to perform a self-cleaning operation. The equipment program controls the built-in water pumps of the two sets of water tanks to turn on, and the built-in valves of the first flushing nozzle 412 and the second flushing nozzle 422 to open. High-pressure water jets are sprayed out from the two sets of flushing nozzles in the form of water columns to clean the sludge remaining on the two sets of stirring rods and to flush the fine mud residue remaining at the bottom of the sludge discharge device 1. The equipment program controls the self-cleaning time to be T2. When the self-cleaning time T2 is up, the equipment program controls the built-in water pumps of the two sets of water tanks to turn off, and the built-in valves of the first flushing nozzle 412 and the second flushing nozzle 422 to close and send a completion signal to the staff.

[0051] By using the built-in water pumps of the two water tanks, the two sets of flushing nozzles and the equipment program together, the sludge remaining on the two sets of stirring rods can be cleaned after the sludge discharge is completed. At the same time, the fine mud residue remaining at the bottom of the sludge discharge device 1 can also be washed clean. There is no need for manual washing by the staff, which reduces cleaning time and cost and lightens the burden on the staff.
