[0004] Although the above patent can treat wastewater through the filtering component, a large amount of dirt is easily accumulated on the surface of the filter net after filtering the sewage. The dirt cannot be discharged automatically and needs to be manually disassembled by staff for treatment, which affects the sewage purification efficiency and reduces the overall practicality of the sewage. For this reason, we provide a municipal sewage purification and drainage device to solve the above problems. Utility Model Content

[0011] Preferably, a sewage outlet communicating with the interior of the sleeve is fixedly opened on one side of the sleeve, and the bottom of the sewage outlet is flush with the slope.

[0012] Preferably, the protruding portion of the fixing plate and one end of the connecting block are both configured as arc surfaces, two connecting blocks are provided, and the two connecting blocks initially abut against the outer wall of the fixing plate.

[0013] The working principle and beneficial effects of the utility model are:

[0014] 1. In the utility model, by setting the cooperation of the filter disc and other structures, the sewage is filtered and the dirt is left through the filter disc, and then the driving motor is started, and the driving rod at the output end of the driving motor is rotated, thereby driving the isolation plate to rotate in a circle, and then driving the filter disc to rotate in a circle, so that the four separated filter screens on the filter disc are respectively rotated from under the guide holes opened on the inner side of the water pass plate, so that the filtered dirt can be removed from under the guide holes, and the new filter screen can be moved to the bottom of the guide holes.
