[0024] Specifically, a filter plate frame 2 13 is provided on one side adjacent to the filter plate frame 1 5, and the filter plate frame 2 13 is provided with the filter element 6 which is the same as the filter plate frame 1 5, and a slide groove for accommodating the filter plate frame 1 5 and the filter plate frame 2 13 is opened in the filter box 2, and the filter plate frame 1 5 and the filter plate frame 2 13 are slidably connected in the filter box 2, and rubber sealing rings 14 are provided on both sides of the filter plate frame 1 5 and the filter plate frame 2 13, and the filter plate frame 1 and the filter plate frame 2 can be moved into the cleaning chamber in turn for cleaning, so that dust and wind sand can be filtered separately to prevent dust from entering the box when cleaning the filter plate frame 1 or the filter plate frame 2.

[0025] Specifically, there are three cleaning rollers 9 and the transmission gears 10, and the filter plate frame 15 and the filter plate frame 2 13 are respectively arranged between adjacent cleaning rollers 9. The cleaning roller 9 and the filter plate frame 15, the filter plate frame 2 13 are in conflict with the filter element 6, and a transmission belt 15 is provided on the outside of the transmission gear 10, and a tooth groove matching the transmission gear 10 is provided inside the transmission belt 15. The transmission gear 10 can drive each cleaning roller 9 to rotate through the transmission belt 15, so that the cleaning roller 9 can rotate to clean the filter element 6 in the filter plate frame 15 and the filter plate frame 2 13.

[0026] Specifically, three air blowing pipes 12 are provided and are respectively arranged under each of the cleaning rollers 9. A nozzle 16 is provided on the air blowing pipe 12. One end of the air blowing pipe 12 extends to the outside of the filter box 2 and is connected to an air storage tank 17. One end of the air storage tank 17 is connected to a main air pipe 18.
