[0022] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings:

[0023] Example 1:

[0024] like Figures 1 to 4As shown, this embodiment discloses an air filtration device, including a frame 1, a tank 2 fixed on the frame 1, a rotating plate 3 rotatably connected to the tank 2 inside the tank 2, a support plate 27 below the rotating plate 3, and multiple partitions 4 evenly fixed between the support plate 27 and the rotating plate 3. The partitions 4 divide the cavity between the support plate 27 and the rotating plate 3 into multiple filter chambers 5, each filter chamber 5 containing a filter module 8. The filter module 8 includes an air guide pipe 9 fixed on the rotating plate 3, a one-way valve fixed above each air guide pipe 9, and a support block 13 below the air guide pipe 9. A fixing pipe 11 is fixed on the support block 13, and the fixing pipe 11 is sleeved on the air guide pipe 9 and rotatably connected to the air guide pipe 9. The support block 13 and the support plate 27 are also connected. A torsion spring 14 is fixed between the support plate 27 and the support plate 27. A winding shaft 15 is rotatably connected to the support plate 27. A filter cloth 16 is fixed on the fixed pipe 11. The end of the filter cloth 16 is fixed on the winding shaft 15. An air inlet pipe 6 is fixed on the tank body 2. An air outlet pipe 7 is fixed on the top of the tank body 2. A rotary motor 28 is fixed on the frame 1. The output end of the rotary motor 28 is fixed to the support plate 27. A sealing plate 35 is fixed on the tank body 2 below the filter chamber 5 at the position of the air inlet pipe 6. A water spray trough 29 is fixed on the tank body 2. A water spray pipe 30 is fixed inside the water spray trough 29. Spray nozzles 31 are evenly fixed on the water spray pipe 30. A winding motor 18 that works with the winding shaft 15 is fixed on the frame 1 below the spray nozzles 31.Air enters the tank 2 through the air inlet pipe 6. Because the top of the filter chamber 5 at the air inlet pipe 6 is blocked by the rotating plate 3 and the bottom is sealed by the sealing plate 35, the filter chamber 5 at the air inlet pipe 6 forms a sealed cavity. Air entering the filter chamber 5 can only exit through the air guide pipe 9. After being filtered by the filter cloth 16, the air is discharged through the air guide pipe 9 to the top of the rotating plate 3, and then discharged through the air outlet pipe 7 for use. After the filter cloth 16 has been filtering for a period of time, a large amount of dust adheres to it, and then the rotating motor 28 drives the support plate. 27 rotates, the support plate 27 drives the rotating plate 3 and each filter module 8 to rotate together, the next filter chamber 5 reaches the position of the air inlet pipe 6 and the air is filtered again by the filter module 8, the filter cotton cloth 16 with dust adhering to it reaches the position of the water spray tank 29, the bottom of the filter chamber 5 at the position of the water spray tank 29 is not blocked by the sealing plate 35, after the electric telescopic rod 22 receives the electrical signal, it is driven to extend, the rotating tube 20 rises, after the positioning hole 23 above the rotating tube 20 is assembled with the positioning block 17 at the bottom of the winding shaft 15, the positioning block 17 locks in place. Inside the positioning hole 23, the take-up motor 18 receives a signal and drives the take-up shaft 15 to rotate. As the take-up shaft 15 rotates, the filter cloth 16 wound on the fixed tube 11 is gradually pulled out from the fixed tube 11. Water is drawn by the water pump and sprayed out through the nozzle 31 on the water spray pipe 30. After the water is sprayed onto the filter cloth 16, the dust and impurities are washed away and separated from the filter cloth 16. The dust is separated from the filter cloth 16 as it flows with the water. When the filter cloth 16 is pulled out from the fixed tube 11, the dust on the filter cloth 16 is cleaned. The rotating motor 28 drives the winding shaft 15 to rotate in the opposite direction. As the torsion spring 14 is tightened, it returns to its natural state. The torsion spring 14 drives the fixed tube 11 to rotate. After the fixed tube 11 gradually winds up the filter cloth 16, the rotating motor 28 stops, the electric telescopic rod 22 shortens, and the rotating tube 20 separates from the positioning block 17. This device can achieve continuous air filtration and automatically clean the filter cloth 16 with dust after a period of filtration. It does not require long-term shutdown to replace parts, thus ensuring continuous air filtration.

[0025] The fixed tube 11 is evenly provided with air inlet holes 12, and the air guide tube 9 is also provided with multiple air guide holes 10.

[0026] The filter cloth 16 is also woven with a mesh-like cotton thread. The mesh-like cotton thread ensures that the filter cloth 16 will not be stretched or deformed.

[0027] Each filter chamber 5 has a drain outlet on its support plate 27. When cleaning the filter cloth 16, the water used for cleaning is discharged and collected through the drain outlet.

[0028] The winding motor 18 has a rotating shaft 16 fixed at its output end. A rotating tube 20 is slidably connected to the rotating shaft 16. The bottom of the winding shaft 15 is fixed with a positioning block 17. The top of the rotating tube 20 is provided with a positioning hole 23 that cooperates with the positioning block 17. A rotating block 21 that is rotatably connected to the rotating tube 20 is also provided on the rotating tube 20. An electric telescopic rod 22 is also fixed on the frame 1. The end of the electric telescopic rod 22 is fixed to the rotating block 21.

Based on the structure and principle of Embodiment 1, this embodiment further includes a warm air trough 32 fixed on the tank 2, multiple fans 34 fixed on the warm air trough 32, and multiple electric heating tubes 33 fixed inside the warm air trough 32. After the filter cloth 16 is cleaned, the support plate 27 rotates again, and the cleaned filter cloth 16 reaches the position of the warm air trough 32. The electric heating tubes 33 are energized and heat up, and the fans 34 are energized and start. The fans 34 drive the heated air to form an airflow, which blows to the filter cloth 16 to dry it. The support plate 27 at the position of the warm air trough 32 is provided with a drain outlet, through which the hot and humid air is discharged.
