[0030] Working principle: When sewage needs to be treated, it can first be input into the sewage tank 22 through the water inlet pipe on the left side of the sewage tank 22. When enough sewage is input for filtering, the cylinder 23 can be started, so that the connecting plate 24 and the sliding frame 25 can be displaced, and then the filter plate 26 can be slid inside the sewage tank 22, so that large particles of impurities and floating objects in the sewage can be filtered from the bottom to the top, and then the motor 29 can be started, and the fan gear 30 can be driven by the motor 29 to rotate, so that the scraper 32 and the rack plate 33 can be meshed with each other, so that the rack plate 33 can reciprocate. At this time, with the reciprocating motion of the rack plate 33, the scraper 32 can slide on the outside of the fixed shaft 31. The scraper 32 slides on the top of the filter plate 26, and the floating objects and large particles of impurities are pushed to the inside of the collection box 27 to complete the collection.

Finally, the heavy metals and other impurities in the sewage can be adsorbed by the activated carbon plate 21. Finally, the sewage filtration is completed and collected in the inside of the filter tank 2. Finally, the filtered sewage can be transported through the outlet pipe at the bottom of the filter tank 2 for reuse.

[0031] When it is necessary to replace the filter frame 18, the filter disc 20 and the activated carbon plate 21, the cylinder 15 inside the fixed frame 3 can be started, so that the movable plate 6 can be displaced, and then the sliding plate 7 can be displaced.

At this time, the sliding frame 9 can slide in the sliding groove 11 with the help of the sliding frame 9, so that the triangular block 10 is displaced, and then the triangular block 10 can slide upward, and then the sliding column 12 can slide out of the sliding groove 17. At this time, the spring 13 will rebound, and the elastic force of the spring 13 can be used to make the displacement of the sliding column 12 more stable. At this time, the sealing block 16 can be taken out, and then the filter frame 18, the filter disc 20 and the activated carbon plate 21 can be taken out for replacement and cleaning. When it is necessary to install, it is only necessary to start the cylinder 15 again to displace the trapezoidal column 8, so that the sliding column 12 can slide in the sliding groove 17, so that the sealing block 16 can be engaged, thereby realizing the installation of the sealing block 16.
