[0023] like Figure 3 and 4As shown, the suction component includes a suction main pipe 16 rotatably set on the sliding mounting plate 14 and a liquid pump 18 fixed on the sliding mounting plate 14.

A plurality of suction branch pipes 17 are provided on the suction main pipe 16. One end of the suction branch pipe 17 is provided with a duckbill-shaped suction head, and the suction head is tangent to the inner wall of the filter cartridge 11. Specifically, the operation of the liquid pump 18 can make the suction main pipe 16 negative pressure, so that it can be sucked through the suction head. The suction head is tangent to the inner wall of the filter cartridge 11, and its distance from the inner wall of the filter cartridge 11 is less than 0.5CM. Under the action of negative pressure, impurities attached to the surface of the filter cartridge 11 can be sucked out.

[0024] like Figure 6 As shown, the driving component includes a motor 21 fixed on the sliding mounting plate 14 and a first gear 22 and a second gear 23 that mesh with each other. The first gear 22 is connected to the main shaft of the motor 21, and the second gear 23 is sleeved on the suction main pipe 16; specifically, the motor 21 drives the first gear 22 to rotate, and the engagement of the first gear 22 and the second gear 23 can drive the suction main pipe 16 to rotate.

[0030] In summary: first, tap water enters the inside of the filter cartridge 11 through the water inlet pipe system 8, and flows into the steady flow compensation tank 3 after being filtered by the stainless steel filter screen; when the PLC controller starts the cleaning program through the timing module, the electric telescopic rod 13 pushes the sliding mounting plate 14 to move along the slide rail of the support frame 10, while the motor 21 drives the first gear 22 to rotate the second gear 23, so that the suction main pipe 16 drives the spiral distributed suction sub-pipes 17 to rotate, and the duckbill-shaped suction head forms a negative pressure suction within a range of 0.5 cm from the inner wall of the filter cartridge 11; the impurity sewage is sucked by the liquid suction pump 18 through the connecting pipe 19 to the filter box 9, and is discharged by the drain pipe after being purified by the multiple filter plates 15 (including filter screens, activated carbon and biological filter membranes); the entire process is cooperatively controlled by the PLC controller to control the displacement of the electric telescopic rod 13, the rotating speed of the motor 21 and the start-stop of the liquid suction pump 18, so as to ensure that the spiral trajectory of the suction sub-pipes 17 and the axial movement completely cover the inner wall of the filter cartridge 11, and the suction main pipe 16 realizes dynamic sealing through the polytetrafluoroethylene guide sleeve and the silica gel sealing ring, and finally realizes the self-cleaning function under the modular flange connection structure (the first flange plate 12 and the second flange plate 20 are pressed and sealed by the gasket through bolts) of the steady flow compensation tank 3 and the filter cartridge 11.
