The second motor 18 drives the mounting shaft 17 and the driving blade 19 to rotate, so that the impurities settled in the sedimentation bucket 8 can be discharged outward evenly and stably, which is convenient for cleaning the impurities inside the filter box 6.

[0056] At the same time, when impurities adhere to the filter screen plate 7 and need to be cleaned, external cleaning water is delivered to the nozzle 10 through the liquid supply hose 24, and sprayed in the opposite direction toward the filter screen plate 7 through the high-pressure nozzle 11 on the nozzle 10, thereby cleaning the filter screen plate 7;

[0057] During this process, the first motor 15 is started, and the lifting screw 13 is driven to rotate by the first motor 15 and the synchronous belt structure 16. The lifting and lowering adjustment of the mounting seat 14 can be controlled by the threaded matching relationship between the mounting seat 14 and the lifting screw 13. The lifting and lowering of the nozzle 10 can be controlled by the lifting and lowering of the mounting seat 14, thereby controlling the lifting and lowering of the high-pressure nozzle 11, and further cleaning the filter screen plate 7 at different heights, thereby enhancing the cleaning adequacy of the filter screen plate 7 and improving the filtering effect of the filter screen plate 7 on impurities in sewage.
