[0023] The quick-change assembly 2 includes a mounting frame 21, the inner wall of the mounting frame 21 is slidably connected to a filter plate 22, the upper outer surface of the filter plate 22 is slidably connected to a clamping plate 23, the upper outer surface of the clamping plate 23 is welded with a fixing column 24, the outer surface of the fixing column 24 is fixedly sleeved with a sealing plate 25, the upper outer surface of the clamping plate 23 is fixedly mounted with a fixing block 26, the upper outer surface of the fixing block 26 is rotatably connected to a rotating member 27, the inner wall of the fixing block 26 is rotatably connected to a gear 28, the outer surface of the gear 28 is meshed with a rack plate 29, and a limiting column 201 is welded to the outer surface of one side of the rack plate 29.

[0024] The mounting frame 21 is fixedly mounted at the bottom of the inner cavity of the device body 1, the rack plate 29 is slidably connected to the inner wall of the fixing block 26, the limiting column 201 slides on the inner wall of the clamping plate 23, and the lower outer surface of the clamping plate 23 is attached to the upper outer surface of the mounting frame 21;

[0025] By clamping the filter plate 22 on the inner wall of the clamping plate 23, and then rotating the rotating member 27 to drive the gear 28 to rotate, the gear 28 drives the two rack plates 29 meshing on the outer surface of the gear 28 to move relative to each other, so that the limiting column 201 slides on the inner wall of the clamping plate 23, and finally makes the limiting column 201 press against the outer surface of the filter plate 22, completing the fixation of the filter plate 22, and then holding the fixing column 24 will drive the filter plate 22 to slide and connect to the inner wall of the mounting frame 21.

[0026] Among them, the automatic cleaning component 3 includes a baffle 31, a rectangular through hole 32 is opened inside the baffle 31, threaded columns 33 are threadedly connected to the inner walls of both ends of the baffle 31, a fixing rod 34 is welded to the lower outer surface of the baffle 31, and a connecting column 35 is rotatably connected to the inner wall of the fixing rod 34, a fan blade 36 is fixedly installed on the outer surface of one end of the connecting column 35, and a cross brush 37 is fixedly installed on the outer surface of the other end of the connecting column 35.

[0031] The working process of the utility model is as follows:

[0032] When the sewage purification device is replacing the filter element, first rotate the cover plate 4 to open the device, then pull the fixing column 24 to drive the filter plate 22 to slide out from the inner wall of the mounting frame 21, and then rotate the rotating member 27 to drive the gear 28 to rotate. At this time, the gear 28 drives the two rack plates 29 meshing on the outer surface of the gear 28 to move relative to each other, so that the limiting column 201 slides on the inner wall of the clamping plate 23, and finally makes the limiting column 201 leave the outer surface of the filter plate 22.

When installing the filter plate 22, it is only necessary to clamp the filter plate 22 on the inner wall of the clamping plate 23, and then rotate the rotating member 27 in the opposite direction to drive the gear 28 to rotate, thereby driving the limiting column 201 to press against the outer surface of the filter plate 22 to complete the fixing of the filter plate 22. , then hold the fixing column 24 to drive the filter plate 22 to slide and connect to the inner wall of the mounting frame 21. At this time, the sealing plate 25 is attached to the upper outer surface of the baffle 31. When sewage enters from the water inlet pipe 5 and passes through the fan blade 36, the fan blade 36 is driven to rotate, thereby driving the cross brush 37 to rotate on one side of the filter plate 22 through the connecting column 35, thereby realizing automatic cleaning of the filter plate 22 and reducing the replacement frequency of the filter plate 22. When we need to repair the fan blade 36, rotate the threaded column 33 so that the threaded column 33 leaves the inner wall of the device body 1. At this time, pull the threaded column 33 to drive the baffle 31 to slide and remove it on the inner wall of the device body 1, so that the fan blade 36 can be repaired and maintained, which greatly facilitates the disassembly and installation of the device and ensures the normal operation of the device.
