The collecting tank is adapted to the rotating plate. Moving blocks are movably installed on the outer walls of both sides of the rotating plate, and scrapers are provided between the moving blocks. The utility model realizes automatic cleaning under uninterrupted filtering by cooperating with the movement of the scrapers on multiple rotating plates, which solves the problem that the existing water treatment filter device lacks the functions of efficient automatic cleaning of filter residues and uninterrupted operation.

[0004] When the device is in use, the filter can be cleaned through the cooperation between the motor, water pump, scraper and other components, but manual adjustment is required during use. Since the filter is arranged inside the device, the operator cannot directly observe the blockage of the filter from the outside, and cannot make timely adjustments. The self-cleaning effect of the overall device is poor. Therefore, an anti-corrosion self-cleaning filter is proposed to solve the above problems. Utility Model Content

[0033] Reference Figure 1 , Figure 2 , Figure 4 The front end of the filter box 11 is provided with a water trough 15 for allowing debris to leave the filter box 11, and the rear end of the diversion box 21 is provided with a connecting groove 19 for allowing debris and sewage to enter the diversion box 21. The water trough 15 and the connecting groove 19 are connected to each other. When the water trough 15 is not blocked, the sewage can directly pass through the water trough 15 and the connecting groove 19 from the inside of the filter box 11 into the inside of the diversion box 21. The top of the cover plate 31 is slidably provided with a block 32 for fixing the cover plate 31, and the top of the diversion box 21 is provided with a card slot 32 for accommodating the card block 32. 4. The card slot 34 and the card block 32 are adapted to each other. When the card block 32 is inserted into the card slot 34, the cover plate 31 will be fixed and cannot move. There are multiple groups of card blocks 32, and the multiple groups of card blocks 32 are symmetrically arranged with respect to the center line of the cover plate 31. The two groups of card blocks 32 will fix the cover plate 31 from both sides respectively. The left end of the card block 32 is fixedly connected with a closing spring 33 for pushing the card block 32 outward. The left end of the closing spring 33 is fixedly connected to the right end of another group of card blocks 32. The closing spring 33 will always push the card block 32 outward so that it cannot be separated from the card slot 34 at will.

[0034] Reference Figure 3 - Figure 5The right end of the filter plate 12 is fixedly connected with a slider 16 for pushing the filter plate 12 to the left. The outer wall of the slider 16 is sleeved with a storage box 14 for accommodating a return spring 18. The rear end of the storage box 14 is fixedly connected to the inner wall of the filter box 11. The storage box 14 can protect the return spring 18 from contacting the water body. The right end of the slider 16 is fixedly connected with a rubber block 17 for preventing water from entering the storage box 14. The right end of the rubber block 17 is fixedly connected with a return spring 18 for pushing the rubber block 17 to the left. The right end of the return spring 18 is fixedly connected to the inner wall of the storage box 14. The return spring 18 will always push the rubber block 17 to the left. The inner wall of the diverter box 21 is fixedly connected with a fixed support 23 for supporting the rotating shaft 23. The fixed block 22 has a front end fixedly connected to a rotating shaft 23 for supporting the rotation of the stopper 24, and the outer wall of the rotating shaft 23 is rotatably connected to the stopper 24 for blocking the connecting groove 19. The inner wall of the stopper 24 is provided with a receiving groove 25 for receiving a torsion spring 26, and the inner wall of the receiving groove 25 is fixedly connected to a torsion spring 26 for driving the stopper 24 to rotate and close. The right end of the torsion spring 26 is fixedly connected to the outer wall of the rotating shaft 23. When water flows into the interior of the diverter box 21 from the connecting groove 19, the water flow can drive the stopper 24 to rotate, and after the water flow decreases, the torsion spring 26 will drive the stopper 24 to re-close the connecting groove 19, thereby preventing the sewage inside the diverter box 21 from flowing back into the interior of the filter box 11.

[0035] Working principle: when the filter plate 12 is blocked, the thrust of the water flow on the filter plate 12 will increase. At this time, the water flow will push the filter plate 12 to move right, and the filter plate 12 will drive the baffle 13 to move right synchronously. The rightward movement of the baffle 13 will expose the water channel 15. At this time, the sewage will flow to the inside of the diversion box 21 through the water channel 15 and the connecting groove 19. While the sewage flows horizontally, it will also drive the debris on the surface of the filter plate 12 to move synchronously to the inside of the diversion box 21. As the debris decreases, the flow capacity of the filter plate 12 will be restored. At this time, the thrust of the water flow on the filter plate 12 will decrease again, and then the reset spring 18 will drive the slider 16 to move left by pushing the rubber block 17. The slider 16 will drive the filter plate 12 to move left and reset. At the same time, the filter plate 12 will drive the baffle 13 to move left to re-close the water channel 15. In this way, a self-cleaning is completed, and the sewage entering the diversion box 21 will flow out along the right end opening of the diversion box 21.

[0036] When the inside of the diverter box 21 needs to be cleaned, the block 32 can be pushed inward to disengage from the slot 34 , and then the cover plate 31 can be moved horizontally to expose the top of the diverter box 21 , and then the inside of the diverter box 21 can be cleaned.

[0037] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
