[0029] In another embodiment provided by the present utility model, as Figure 1 shown, a plurality of slots 5 are opened on the front outer wall of the filter box body 1, and an insertion plate 4 is inserted inside the slots 5. A handrail 6 is arranged on the top outer wall of the insertion plate 4. By pulling the handrail 6, the handrail 6 drives the insertion plate 4 to move in the slots 5, facilitating the staff to take out the filter net 13.

[0030] In still another embodiment provided by the present utility model, as Figure 2 、 Figure 4 and Figure 5 shown, the inner wall of the filter box body 1 is rotatably connected with a threaded rod 20 through a bearing, and a lifting box 21 is threadedly sleeved on the outer wall of the threaded rod 20. A scraping plate 23 is arranged on the outer wall of the lifting box 21, and the scraping plate 23 is in contact with the outer wall of the filter net 13. The lifting box 21 drives the scraping plate 23 to move, and the scraping plate 23 contacts the filter net 13, scraping off the impurities that are not easily shaken off and adhering to the filter net 13 and falling into the lifting box 21, facilitating the cleaning of the impurities.

[0031] In an embodiment provided by the present utility model, as Figure 4 and Figure 5As shown, a lifting motor 17 is fixedly mounted on the outer wall of one side of the filter box body 1 through bolts, and a lifting transmission rod 18 is arranged on the output shaft of the lifting motor 17.

[0034] Working principle: When in use, the sewage is connected to the sedimentation tank 2. The sedimentation tank 2 allows the silt and sand in the sewage to settle, which is convenient for subsequent multi-stage filtration and can avoid excessive silt and sediment in the sewage, resulting in frequent cleaning of the sediment in the filtration process, saving labor costs. The settled sewage enters the water inlet pipe 26 through the water pump 25. The sewage in the water inlet pipe 26 enters the filter box body 1. The rotation motor 7 is started, and the rotation motor 7 drives the rotation rod 8 to rotate. The rotation rod 8 drives the cam 9 to rotate.

The push plate 11 stretches the vibration spring 12, and the vibration spring 12 provides a pulling force. The push plate 11 drives the filter net 13 to move. The filter net 13 presses the extrusion rod 15, and the extrusion rod 15 moves in the extrusion groove 14. The extrusion rod 15 compresses the extrusion spring 16, and the extrusion spring 16 provides an elastic force, enabling the filter net 13 to move up and down in the filter box body 1, thereby realizing the function of shaking off the impurities attached to the filter net 13 and avoiding excessive impurities attaching to the filter net 13, which may cause the sewage to be unable to pass through the filter net 13 and reduce the filtration rate. When there is too much organic sediment and sand in the filter box body 1, the filter cover 28 is opened, and the lifting motor 17 is started. The lifting motor 17 drives the lifting transmission rod 18 to rotate. The lifting transmission rod 18 drives the driving bevel gear 19 to rotate. The driving bevel gear 19 meshes with the driven bevel gear 22, and the driven bevel gear 22 drives the threaded rod 20 to rotate. The threaded rod 20 drives the lifting box 21 to move through threading. The lifting box 21 drives the scraper 23 to move. The scraper 23 contacts the filter net 13 to scrape off the stubborn impurities attached to the filter net 13, realizing the function of cleaning the impurities accumulated in the filter box body 1. When the filter net 13 needs to be replaced, the handrail 6 is pulled. The handrail 6 drives the insertion plate 4 to move. The insertion plate 4 moves in the insertion slot 5. The filter net 13 is pulled out, and a new filter net 13 is inserted between the clamping blocks 24, enabling the filter net 13 to be vertically placed in the filter net 13 to avoid the water flow knocking down the filter net 13. The insertion plate 4 is inserted into the insertion slot 5, which facilitates the staff to replace the filter net 13 and reduces the difficulty of replacing the filter net 13.
