When working, clean water is extracted by the water pump 22, and the clean water is transported to the spray head 23 through the spray pipe 23 after being pressurized by the water pump 22, and sprayed to the filter barrel 4 through the spray head 23, so that the surface of the filter barrel 4 is rinsed by high-pressure clean water, the filter barrel 4 is cleaned, and the filtering effect of the filter barrel 4 is guaranteed.

[0030] A filter cloth is fixedly mounted on the periphery of the filter screen barrel 4, and the filter cloth covers the periphery of the filter screen barrel 4. The filter cloth mesh is finer, which can further improve the filtering effect of the device.

[0033] Working principle:

[0034] When using the present device, the outlet pipe 6 is connected to a water pump (the water pump is a prior art and will not be described in detail here). First, sewage is added to the filter box 1. After the sewage is filtered through the filter screen barrel 4, it is finally pumped out through the outlet pipe 6 and the elbow 7 by the water pump to achieve sewage filtration. During the filtration process, if the water level in the filter box 1 rises, it can be determined that the mesh at the bottom of the filter screen barrel 4 is blocked by impurities such as sludge. At this time, the filtration effect and efficiency of the filter screen barrel 4 are reduced. The stepper motor 9 can be started by the controller to drive the first roller 10 to rotate. The first roller 10 drives the rotating shaft 3 to rotate through the first belt 12 and the second roller 11. The rotation of the rotating shaft 3 drives the filter screen barrel 4 to rotate, and the unblocked side of the top of the filter screen barrel 4 is rotated into the sewage, thereby ensuring the filtration effect of the present device.
