The mounting frame 6 is installed at the bottom of the frame 1, and the drive box 7 is installed at the bottom of the mounting frame 6. The mounting frame 6 has a through hole inside. 8. A rotating sleeve 9 is movably installed inside the through hole 8. The top end of the rotating sleeve 9 is fixedly connected to the bottom end of the second distribution plate 4. A rotating shaft 10 is movably installed inside the rotating sleeve 9. The top end of the rotating shaft 10 is fixedly connected to the bottom end of the first distribution plate 2. A first bevel gear 11 is installed at the bottom end of the rotating shaft 10. A second bevel gear 12 is installed at the bottom end of the rotating sleeve 9. A third bevel gear 13 is provided on the left side of the first bevel gear 11 and the second bevel gear 12. The first bevel gear 11, the second bevel gear 12 and the third bevel gear 13 are vertically distributed and mesh with each other. A motor 14 is installed on the left side of the drive box 7. The output end of the motor 14 is fixedly connected to the left side of the third bevel gear 13.

[0025] Specifically, such as Figure 1 , Figure 2 and Figure 3 As shown, during use, when the motor 14 starts and drives the third bevel gear 13 to rotate, the first bevel gear 11 and the second bevel gear 12 can rotate synchronously, and with the assistance of the rotating sleeve 9 and the rotating shaft 10, the first distribution plate 2 and the second distribution plate 4 can be driven to rotate in opposite directions.

[0026] The top of the frame 1 is provided with a mounting sleeve 15. The inner side wall of the mounting sleeve 15 is fixed with a flow guide 16. The surface of the mounting sleeve 15 is provided with external threads, and the inside of the frame 1 is provided with internal threads. The bottom surface of the flow guide 16 is provided with a mounting groove 17. Several mounting grooves 17 are provided on the bottom surface of the flow guide 16. The several mounting grooves 17 are symmetrically distributed. A ball bearing 18 is movably installed inside the mounting groove 17.

[0027] Specifically, such as Figure 1 and Figure 4 As shown, during use, with the assistance of the thread, the mounting sleeve 15 is installed at the opening above the frame 1 for use. The guide platform 16 on the inner side wall can assist in the guide operation. The ball bearings 18, which are movably installed on the bottom side, are symmetrically pressed on the surface of the top of the first distribution plate 2, which can assist in the limiting treatment of the first distribution plate 2.

[0028] The front end of the mounting bracket 6 is equipped with a cleaning table 19. The cleaning table 19 has a slot 20 inside, and a scraper 21 is inserted into the slot 20.

[0030] Working principle: In use, the first distribution plate 2 and the second distribution plate 4 are stacked inside the frame 1 and are movably connected. First air holes 3 and second air holes 5 are respectively provided through their surfaces. The airflow passes through the first air holes 3 and second air holes 5 and moves upwards, contacting the subsequent dust removal components. When the motor 14 starts and drives the third bevel gear 13 to rotate, the first bevel gear 11 and the second bevel gear 12 can rotate synchronously. With the assistance of the rotating sleeve 9 and the rotating shaft 10, the first distribution plate 2 and the second distribution plate 4 can be driven to rotate in opposite directions. During this process, the first air holes 3 and the second air holes 5 on the surface are staggered, allowing adjustment of the size of the air holes between them. Simultaneously, the second distribution plate... Plate 4 serves as the air inlet, and its surface is prone to adhering to debris. As the second distribution plate 4 rotates, it comes into contact with the scraper 21, which assists in cleaning the surface of the second distribution plate 4. In conjunction with subsequent backflushing devices, the second distribution plate 4 can be further cleaned. With the assistance of threads, the mounting sleeve 15 is installed at the opening above the frame 1 for use. The guide platform 16 on the inner wall can assist in the flow guiding operation. The ball bearings 18, which are movably installed on the bottom side, symmetrically press against the top surface of the first distribution plate 2, which can assist in the limiting treatment of the first distribution plate 2. Subsequently, during the backflushing cleaning operation, the mounting sleeve 15 can also assist in the backflushing airflow or liquid to converge at the first distribution plate 2 and the second distribution plate 4.
