[0049] During use, the circulating cooling water carrying impurities and particles is injected into the filter assembly 300 through the inlet 303a-2. The wastewater injected into the filter assembly 300 enters the filter cartridge 302a. After being filtered through the filter holes 302b, the impurities and particles remain in the filter cartridge 302a. The filtered circulating water flows into the collection tank 301a, and then the filtered circulating water is reinjected into the open cooling water system through the outlet 301b for recycling. This maintains the cleanliness and quality of the circulating water and extends the life of the steam turbine.

[0050] During the filtration process, the pressure sensor (CJ18-20A) connected to the side of the sealing plate 103a detects an increase in water pressure inside the filter element 302 and sends a signal to the PLC500 (S7-300). The PLC500 controls the opening of the water pump 401c on the suction component 401. The water pump 401c sucks up the impurities adhering to the filter element through the suction pipe 401a. When the sewage sucked up by the suction pipe 401a passes through the sewage discharge chamber 401d, large particles of impurities and particulate matter are separated and discharged through the sewage discharge block 403. The sewage with large particles of impurities and particulate matter removed is reinjected into the water tank 300 for recycling by the drain pipe 401b and the water pump 401c. In this way, by setting up the cleaning component 400 to clean the impurities and particulate matter in the filter element 302, the need for frequent maintenance and cleaning by staff is eliminated, thus enhancing the circulation efficiency of the circulating water.

Threaded surface 402a-1 When the threaded rod 402a rotates, the sliding block 402b, in conjunction with the sliding block 402b, drives the sliding block 402b to slide back and forth. The limiting groove 402a-2, in conjunction with the limiting spring block 402c, controls the position of the threaded rod 402a. When the limiting spring block 402c is engaged in the outer limiting groove 402a-2, the first helical gear 402d engages with the mating tooth 402a-4, causing the threaded rod 402a to rotate clockwise. When the limiting spring block 402c is engaged in the inner limiting groove 402a-2, the second helical gear 402e engages with the mating tooth 402a-4, causing the threaded rod 402a to rotate counterclockwise.

[0055] The sliding block 402b includes a threaded hole 402b-1, a connecting block 402b-2, a push post 402b-3, and a connector 402b-4. The threaded hole 402b-1 is located on the side of the sliding block 402b, the connecting block 402b-2 is located on the side of the sliding block 402b, the push post 402b-3 is connected to the connecting block 402b-2, and the connector 402b-4 is located on the side of the push post 402b-3.

The second helical gear 402e includes a second reversing tooth 402e-2, which is located on the side of the first helical gear 402d. On the side of the second helical gear 402e; the threaded hole 402b-1 meshes with the threaded surface 402a-1, the connecting block 402b-2 connects to the push column 402b-3 and cooperates with the mating barrel 303b to ensure that the sliding block 402b can only slide back and forth, the push column 402b-3 connects to the connector 402b-4, the push column 402b-3 and the hole on the sealing plate 303a cooperate to allow the sliding block 402b to slide back and forth, the connector 402b-4 connects to the drain block 403, and the drain block drives the suction component 401 to reciprocate. When the first reversing tooth 402d-1 and the second reversing tooth 402e-2 are engaged with the mating tooth 402a-4, they drive the spiral rod 202a to rotate.

[0056] The sewage block 403 includes a sewage trough 403a, a matching pipe 403b, and a connecting groove 403c. The sewage trough 403a, matching pipe 403b, and connecting groove 403c are located on the side of the sewage block 403. The connecting groove 403c is connected to the connector 402b-4. When the sewage trough 403a and the sewage bin 401d are in operation, the water pump 201b continuously pumps water. When separated, the impurities and sludge in the sewage bin 401d are discharged and cleaned. The matching pipe 403b and the suction pipe 401a are in operation to ensure the operation of the sewage block 403 and the sewage bin 401d. The connecting groove 403c is connected to the connector 402b-4 so that the sliding block 402b can drive the connecting groove 403c to move back and forth.

[0057] During use, the pressure sensor (CJ18-20A) connected to the side of the sealing plate 103a detects an increase in water pressure inside the filter element 302 and sends a signal to the PLC500 (S7-300). The PLC500 controls the opening of the water pump 401c and motor 301c-1 on the suction component 401. The water pump 401c sucks up impurities adhering to the filter element through the suction pipe 401a. When the sewage sucked up by the suction pipe 401a passes through the sewage discharge chamber 401d, large particles and particulate matter are separated by the filter screen set on the drain pipe 401b. At this time, the motor 301c-1 drives the drive gear 301c-4 to move. -4 drives the first helical gear 202 to move, the first helical gear 402d drives the threaded rod 402a to rotate clockwise, the threaded rod 402a drives the filter element 302 to rotate, the threaded rod 402a drives the sliding block 402b to slide to the left, the sliding block 402b pushes the sewage block 403 out of the sewage discharge chamber 401d to discharge sewage and prevent the sewage block 401b from having condensed sludge affecting the working efficiency of the water pump. After the sewage block 403 is pushed out, one end is still limited by the sewage discharge chamber 201, so that part of the sewage block 403 still remains in the sewage discharge chamber 401d. Then the sliding block 402b pushes the sewage block 403, the sewage block 403 drives the suction component 401 to push to the left end together; limit plate 401e-2 compresses the spring 303b-3. The spring force pushes the sliding block 402b to the right, causing the threaded rod 402a to move a short distance to the right. The limiting spring block 402c engages with the inner limiting groove 402a-2. The second reversing gear 402e-2 engages with the mating gear 402a-4. The second helical gear 402e drives the threaded rod 402a to rotate counterclockwise. The threaded rod 402a drives the sliding block 402b to slide to the right. The sliding block 402b pulls the sewage block 403 into the sewage collection box 303c. The water pump 401c begins to continuously suck out impurities and particulate matter along with sewage through the suction head 401a-1. When the contaminant 401 moves to the right end, it switches to the first helical gear 402d via spring 303b-3, which drives the threaded rod 402a to rotate clockwise. The sliding block 402b pushes out the discharge block 403, discharging large impurities and particulate matter. The wastewater, now free of large impurities and particulate matter, is reinjected into the water tank 300 by the drain pipe 401b and the water pump 401c for recycling. This cycle repeats continuously. By setting up the cleaning component 400 to clean impurities and particulate matter in the filter element 302, the filter achieves self-cleaning of the filter element 302 until the pressure sensor pressure drops to a normal level. This eliminates the need for frequent maintenance and cleaning by staff, enhancing the circulation efficiency of the circulating water.
