Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-4 This utility model provides a technical solution: a filter for air separation equipment with self-cleaning function, wherein an air inlet 101 is provided on the upper side of the filter box 1, and several diverter plates 2 are installed alternately inside the upper side of the filter box 1, and a fixing frame 3 is installed inside the filter box 1 below the diverter plates 2, and several self-cleaning filter screen mechanisms 4 are installed on the fixing frame 3.

[0025] In a further embodiment, a dehumidifier cylinder 1011 is detachably installed inside the air inlet 101. The dehumidifier cylinder 1011 is existing technology and will not be described in detail. The dehumidifier cylinder 1011 can absorb moisture in the gas.

[0026] Specifically, an air outlet 6 is provided on the lower side of the filter box 1, and the air outlet 6 is connected to an air pump. The air pump allows gas to enter through the air inlet 101 and finally be discharged through the air outlet 6.

[0027] To further explain, a door is provided on one side of the filter box 1 to facilitate the maintenance or cleaning of the internal equipment of the filter box 1 in the future. An ozone generator 7 is installed on the outside of the filter box 1 and is connected to the inside of the filter box 1. The ozone generator 7 produces ozone, which neutralizes and oxidizes substances in the air. The diversion plate 2 can increase the contact time between air and ozone.

[0028] Specifically, the self-cleaning filter mechanism 4 includes a fixing ring 401, which is connected to the fixing frame 3 by bolts. An annular filter mounting plate 402 is fixedly installed at the bottom of the fixing ring 401. The annular filter mounting plate 402 has several sets of ventilation holes to facilitate the flow of filtered gas. A filter 403 is fixedly installed inside the annular filter mounting plate 402, and the bottom of the annular filter mounting plate 402 is connected to the dust collection tank 404. A cleaning brush mechanism 5, which works in conjunction with the filter 403, is installed inside the annular filter mounting plate 402. The cleaning brush mechanism 5 includes a drive motor 501, which is located inside the heat dissipation protective cover. A connecting bracket for use with a drive motor 501 is installed on the top of the fixed ring 401. The drive motor 501 can drive the rotating rod 502, which is rotatably arranged inside the annular filter screen mounting plate 402, to rotate. Several sets of open sleeves 503 are symmetrically arranged on the outer side of the rotating rod 502. A moving plate 504 is slidably connected inside the open sleeve 503. One side of the moving plate 504 is connected to the inner wall of the open sleeve 503 by a spring 505, and the other side of the moving plate 504 is connected to the long rod cleaning brush 507 by a connecting arm 506. The long rod cleaning brush 507 is in contact with the filter screen 403. By setting the spring 505, the long rod cleaning brush 507 can always be in contact with the filter screen 403.

[0029] To further explain, the dust collection tank 404 has a dust outlet at the bottom, and a matching sealing cap is installed on the dust outlet.

[0030] In use, the filter screen 403 can filter impurities and dust in the gas. When it is necessary to clean the blockage of the filter screen 403, the drive motor 501 is turned on. Under the action of the drive motor 501, the rotating rod 502 rotates, thereby driving the open sleeve 503 and the connecting arm 506 to rotate and move. Under the action of the rotating and moving connecting arm 506, the long rod cleaning brush 507 moves, thereby brushing the filter screen 403 and brushing off the blockage. The brushed-off blockage enters the dust collection tank 404 for collection.
