[0029] When in use, first introduce the sewage into the interior of the filter box 2 through the two water inlet pipes 4, then start the motor 62 to drive the transmission rod 63 to rotate, and then the transmission rod 63 will drive the crushing roller 64 to rotate, thereby crushing the debris in the sewage, and then the sewage is filtered through the filter screen 52 inside the rectangular frame 51. Since the bottom of the rectangular frame 51 is supported by the hydraulic rod A58, when the impurities on the upper end of the filter screen 52 reach a certain weight, it will drive the rectangular frame 51 to move downward as a whole, and then squeeze the hydraulic rod A58 to move it toward the inside of the hydraulic warehouse A57, and then the hydraulic rod B59 at the other end of the hydraulic warehouse A57 will rise accordingly. When the rectangular frame 51 descends, the inner magnet 54 will drive the rotating shaft A514 and the moving plate 515 to descend through the permanent magnet 53. When the moving plate 515 descends, it will slide inside the slide groove A519, which will bring When the telescopic rod 511 is moved downward, since the upper end of the telescopic rod 511 is restricted by the fixed block 510, the upper end of the telescopic rod 511 and the bevel gear B518 will not descend, and the upper end of the hydraulic rod B59 will drive the upper end of the telescopic rod 511 and the bevel gear B518 to rise through the linkage block 516, and then the bevel gear B518 will mesh with the bevel gear A517, and then the rotation of the transmission rod 63 can be transmitted to the telescopic rod 511, then the telescopic rod 511 will rotate accordingly, and then the worm 512 on its outer wall will rotate, and then the worm gear 513 meshed with it will rotate accordingly, thereby driving the rotating shaft A514 to rotate, and then driving the permanent magnet 53 to rotate, and then the magnetizer 54 will rotate accordingly, and then the reciprocating screw rod 55 will rotate accordingly, and then the scraper 56 threadedly connected to its outer wall will move accordingly, and then the surface of the filter screen 52 will be cleaned.

[0030] For example 2, please refer to Figures 1-8 The stirring and knocking assembly 7 includes a chute B71, which is opened on the inner side of the rectangular frame 51. The side of the scraper 56 is fixedly connected to a connecting plate 72, and the connecting plate 72 is slidably connected to the inside of the chute B71.

[0032] When in use, when the scraper 56 moves, it will drive the connecting plate 72 on its side to slide inside the slide groove B71. When the connecting plate 72 moves to contact the side of the tooth plate 710, it will push the tooth plate 710 to rotate, and then the transmission gear 79 meshing with it at its lower end will rotate, and then the shaft C78 will rotate, and then the bevel gear C711 at the front end of the shaft C78 will drive the bevel gear D712 meshing with it to rotate, and then drive the shaft B73 to rotate. When the shaft B73 rotates, it will drive the connecting block A74 to rotate, and then the connecting block A74 outer wall hinged connection will rotate under the action of centrifugal force. Rod A75 will drive the knocking ball 76 to generate a force to open toward the outward end, and the cylinder connecting rod A75 will drive the movable block 77 to slide on the outer wall of the rotating shaft B73 through the connecting rod B716. When the knocking ball 76 rotates, it will knock on the bottom of the filter screen 52 that has just dropped. In addition, when the tooth plate 710 moves, the connecting block B715 at its upper end will slide inside the slide groove C713, and then squeeze the spring A714. Since the two sides of the connecting plate 72 are set as inclined surfaces and are retractable, when the connecting plate 72 cannot push the tooth plate 710, it will retract toward the upper end, so as not to cause the scraper 56 to be unable to move.

[0033] For example three, please refer to Figures 1-8 The flipping assembly 8 includes a cam 81, which is fixedly sleeved on the outer wall of the rotating shaft B73. The side of the filter box 2 is fixedly connected to the hydraulic warehouse B82.

The outer wall of the rotating shaft D87 is fixedly sleeved with a flip plate 88 and one end of the rotating shaft D87 passes through the sterilization box 3 and is fixedly connected to a swing rod 89. Through the flipping action of the flip plate 88, the fluidity of the sewage in the sterilization box 3 is enhanced, and the sterilization efficiency of the ultraviolet sterilization lamp 92 is improved. The outer wall of the swing rod 89 is provided with a slide groove D811. The outer wall of the lifting block 86 is fixedly connected with a sliding shaft 810, and the sliding shaft 810 is slidably connected to the inside of the slide groove D811.

Through ultraviolet sterilization, it is ensured that the sewage meets environmental protection emission standards and avoids secondary pollution to the environment.

[0035] During use, when the rotating shaft B73 rotates, the cam 81 fixed on its outer wall will rotate accordingly. During the rotation of the cam 81, the hemisphere 85 at its lower end will move back and forth under the joint action of the spring B812, thereby driving the hydraulic rod C83 at its lower end to move back and forth inside the hydraulic bin B82, and then the hydraulic rod D84 at the other end of the hydraulic bin B82 will move to the upper end, thereby driving the lifting block 86 to move back and forth, then the sliding shaft 810 on the outer wall of the lifting block 86 will slide inside the slide groove D811, thereby driving the swing rod 89 to swing, and then driving the flip plate 88 to swing through the rotating shaft D87, thereby enhancing its fluidity during the process of the ultraviolet sterilization lamp 92 moving and sterilizing inside the sterilization box 3, thereby improving the sterilization efficiency.
