[0004] The above prior art often has the following problems when used:

[0005] When the existing solid waste filtering device for sewage treatment is in use, due to long-term use, solid waste impurities will accumulate on the filter mesh, which will cause a sharp decrease in the subsequent filtration rate, thereby affecting the filtration efficiency. At the same time, when separating solid waste impurities and garbage, after the traditional device completes the filtration, the surface of the solid waste impurities is still contaminated with sewage, which will affect the subsequent recovery of useful substances. In addition, for some sewage that can be reused after filtration, this makes it impossible to maximize the recycling efficiency, and the sewage brought out is also prone to cause secondary pollution.

Four drain plates 18 are equidistantly fixedly connected to the upper surface of the No. 1 filter grid 2, and the four drain plates 18 are respectively arranged in pairs with respect to the No. 1 through groove 10, so that solid waste will not accumulate in the corners of the No. 1 shell 1, and the solid waste pushed by the push plate 7 is guided.

[0026] The detailed working process of the utility model is as follows:

[0027] During use, when solid waste filtering is required, the sewage to be operated is poured onto the top of the No. 1 filter screen 2 in the No. 1 housing 1, and the solid waste impurities are filtered through the No. 1 filter screen 2. At this time, the motor 3 is started, and the motor 3 drives the No. 1 rotating shaft 4 to rotate, thereby driving the rotating rod 5 to revolve, and the rotating rod 5 will rotate and slide in the guide groove body 6, so that the guide groove body 6 moves back and forth left and right under the guidance of the two guide rods 8, thereby driving the push plate 7 to move left and right.

The rotation of the two gears 15 will drive the two cylinders 13 to rotate. Through such a relatively fast reciprocating rotation, centrifugal force is used to achieve dehydration of the solid waste in the cylinder 13. The wastewater contaminated on the surface of the solid waste will be discharged through the filter holes on the side wall of the cylinder 13, and then collected with the filtered sewage through the No. 2 through groove 11, so as to achieve the dehydration operation of the filtered solid waste, thereby facilitating the subsequent recovery of some useful substances and improving the recovery efficiency of sewage and useful substances.
