[0002] Patent announcement number CN220405000 discloses a self-cleaning filter plate structure for sewage treatment, including a mounting plate, a positioning plate is fixedly connected to the opposite side of the mounting plate, a clamping plate is movably connected to the surface of the positioning plate, a connecting plate is fixedly connected to the opposite side of the clamping plate, and a filtering cross plate is arranged on the opposite side of the connecting plate. The utility model enables the filter plate structure for sewage treatment to have the advantage of self-cleaning function through the cooperation of the mounting plate, the positioning plate, the clamping plate, the connecting plate, the filter cross plate, the fixing frame, the casing, the motor, the screw, the threaded sleeve, the connecting pipe, the cleaning plate, the drainage hole, the brush, the water spraying plate, the water injection pipe, the groove, the electric push rod, the sewage discharge plate and the sewage discharge groove, thereby solving the problem that the existing filter plate structure for sewage treatment requires the staff to clean the filter plate regularly, but the operation of manually cleaning the filter plate has a certain lag, so it is difficult to ensure that the filter plate always maintains a clean state. Although this method can perform automatic cleaning, the cleaning method is not thorough enough, and the filter hole cannot be fully deeply cleaned. The impurities after cleaning cannot be collected separately, which reduces the self-cleaning effect. For this reason, we propose a self-cleaning filter plate structure for sewage treatment.

[0022] The following examples are used to illustrate the present invention, but cannot be used to limit the scope of protection of the present invention. The conditions in the examples can be further adjusted according to specific conditions, and simple improvements to the method of the present invention under the premise of the concept of the present invention are all within the scope of protection claimed by the present invention.

[0023] See also Figure 1-5The utility model provides a self-cleaning filter plate structure for sewage treatment, including a frame 1, a filter plate 2 is fixed to the inner wall of the frame 1, filter holes 3 are opened on the filter plate 2 along the rectangular array direction, there is a certain distance between each vertical filter hole 3, an adjustment plate 4 is slidably connected to the top of the filter plate 2, a plurality of parallel cleaning strips 9 are fixed to the bottom side wall of the adjustment plate 4, the cleaning strips 9 are located at the distance between the vertical filter holes 3, a cleaning groove 10 is opened on the side wall of the cleaning strip 9 close to the adjustment plate 4, a movable plate 11 is slidably connected between the inner walls of the cleaning groove 10, and the movable plate 11 is close to the side wall of one side of the filter plate 2 A cleaning brush 12 is connected. When the cleaning brush 12 contacts the filter hole 3, the bristles of the cleaning brush 12 will pass through the filter hole 3 to deeply clean the impurities inside the filter hole 3. A return spring 13 is connected to the side wall of the other side of the movable plate 11. The other end of the return spring 13 is fixed to the side wall of the cleaning groove 10. The elastic force of the return spring 13 can ensure that the cleaning brush 12 and the filter hole 3 are fully contacted and cleaned. A protection box 6 is fixed to the top of the side wall of the filter plate 2. A driving motor is connected to the inside of the protection box 6. The output shaft of the driving motor passes through the protection box 6 and is fixed with an incomplete gear 7. An adjustment channel 5 is opened on the surface of the adjustment plate 4. The full gear 7 is located inside the adjustment channel 5. Adjustment racks 8 are provided on the side walls of the adjustment channel 5 along the length direction thereof. The adjustment racks 8 are meshed and driven with the incomplete gear 7, and can automatically and continuously clean the filter hole 3, so that the impurities blocked inside the filter hole 3 are effectively cleaned. A collection groove 14 is provided on the bottom side wall of the frame 1. A water flow hole 17 is provided on the collection groove 14 to automatically discharge a small amount of sewage entering the collection groove 14. A baffle 15 slidably connected to the bottom side wall of the frame 1 is provided on the upper surface of the collection groove 14. The baffle 15 seals the collection groove 14. The baffle 15 A connecting strip 16 is fixed to the top of the filter plate 2, and the other end of the connecting strip 16 passes through the bottom of the filter plate 2 to form an arc-shaped structure. The arc-shaped structure of the connecting strip 16 is located on the moving track of the cleaning strip 9. When the cleaning strip 9 moves, the arc-shaped structure of the connecting strip 16 is squeezed, so that the connecting strip 16 drives the baffle 15 to move, and the baffle 15 opens the collection slot 14, so that the cleaned impurities fall into the collection slot 14 for collection. A connecting spring 18 fixed to the side wall of the filter plate 2 is installed at one end of the baffle 15. The connecting spring 18 can ensure that the baffle 15 effectively closes the collection slot 14 without external force.

[0024] This solution has the following working process: the frame 1 is installed on the sewage pipe or the designated position. The installation method can be connected by a detachable method such as bolts, and then the sewage is filtered through the filter hole 3. After a period of time, the drive motor is started, and the drive motor drives the incomplete gear 7 to rotate. The meshing transmission connection between the incomplete gear 7 and the adjustment rack 8 drives the adjustment plate 4 to move back and forth in a cycle, so that the adjustment plate 4 drives the cleaning bar 9 to move back and forth in a cycle, so that the cleaning bar 9 drives the cleaning brush 12 to move back and forth in a cycle, and the cleaning brush 12 is in full contact with the filter hole 3 to clean the impurities inside the filter hole 3, so that the cleaned impurities fall into the collection tank 14 directly below. At the same time, the cleaning bar 9 squeezes the arc structure of the connecting bar 16, so that the connecting bar 16 drives the baffle 15 to move, so that the baffle 15 opens the collection tank 14, so that the impurities fall into the collection tank 14 for collection. When the connecting bar 16 is not squeezed, under the elastic force of the connecting spring 18, the baffle 15 closes the collection tank 14 without affecting the normal sewage filtration process.
