[0038] When the connecting rod 405 moves along the inner surface of the horizontal plate 3, since the outer surface of the connecting rod 405 and the inner surface of the front end of the rotating rod 402 are movably connected, the rotating rod 402 will rotate with the fixed rod 401 as the axis under the action of the connecting rod 405, so that the inner wall of the rotating rod 402 generates a thrust on the outer surface of the vertical rod 403, pushing the vertical rod 403 to move along the inner surface of the horizontal plate 3 with the scraper 404, so as to achieve the cleaning of solid dirt, thereby preventing the wastewater purification treatment device from being blocked and affecting the wastewater treatment progress.

[0039] Wherein, the driving mechanism 5 comprises:

[0047] Among them, a pressure block 10 is movably sleeved at the top of the collection box 8, and a vertical rod 11 is fixedly installed at the top of the pressure block 10. The top of the vertical rod 11 penetrates the collection box 8 and extends to the outside of the collection box 8. The top of the right end of the vertical rod 11 is movably connected to the left end of the outer shell 2.

[0048] When the vertical rod 11 moves downward, it will move with the pressing block 10, thereby compressing the solid pollutants.

[0049] Among them, a first motor 12 is fixedly installed on the left side of the top of the horizontal plate 3, and a rotating shaft 13 is fixedly sleeved on the other end of the output shaft of the first motor 12. A disc 14 is fixedly sleeved on the left end of the outer surface of the rotating shaft 13. A movable rod 15 is hinged on the top of the left end of the disc 14. The right end of the movable rod 15 is movably connected to the left end of the disc 14, and the bottom end of the movable rod 15 is hinged to the top of the vertical pole 11. The movable rod 15 will move the vertical pole 11.

[0050] When the first motor 12 is started, the rotating shaft 13 drives the disc 14 to rotate, so that the disc 14 rotates with the top of the movable rod 15, and then the bottom end of the movable rod 15 generates a thrust on the vertical rod 11, pushing the vertical rod 11 to move downward.

[0051] Among them, a second motor 16 is fixedly installed on the left side of the bottom end of the outer shell 2, and the other end of the output shaft of the second motor 16 is fixedly sleeved with a first round rod 17. The top end of the first round rod 17 penetrates the outer shell 2 and extends to the interior of the outer shell 2. The outer surface of the first round rod 17 is fixedly sleeved with a first stirring rod 18, and the bottom end of the outer surface of the first round rod 17 is fixedly sleeved with a driving gear 19, and the top end of the driving gear 19 is movably connected to the bottom end of the outer shell 2.

[0052] When the second motor 16 is started, the first round rod 17 will drive the first stirring rod 18 and the driving gear 19 to rotate.

[0053] Among them, a second round rod 20 is movably sleeved on the right side of the bottom end of the outer shell 2, the top end of the second round rod 20 penetrates the outer shell 2 and extends to the inside of the outer shell 2, the outer surface of the second round rod 20 is fixedly sleeved with a second stirring rod 21, and the bottom end of the outer surface of the second round rod 20 is fixedly sleeved with a driven gear 22, the top end of the driven gear 22 is movably connected to the bottom end of the outer shell 2, the outer surface of the driven gear 22 is meshedly connected to the outer surface of the driving gear 19, and the driven gear 22 will drive the second round rod 20 to rotate.

[0054] When the driving gear 19 rotates, the driven gear 22 meshing with the driving gear 19 will drive the second round rod 20 to rotate in the opposite direction, and the second stirring rod 21 and the first stirring rod 18 are arranged alternately.

[0055] A sewage valve 23 is fixedly sleeved on the bottom of the right end of the shell 2 , and a reagent adding valve 24 located below the first filter plate 6 is fixedly sleeved on the top of the right end of the shell 2 .

[0056] When the reagent adding valve 24 is opened, the reagent can be added into the housing 2 through the reagent adding valve 24 .

[0057] Working principle and usage process:

[0058] First, the operator opens the reagent adding valve 24, adds the reagent into the interior of the shell 2, and then closes the reagent adding valve 24, and then inputs the wastewater added with the flocculant into the shell 2 and filters it through the first filter plate 6 and the second filter plate 7. After the filtration is completed, the operator starts the driving motor 501 to rotate the screw rod 502. Since the outer surface of the screw rod 502 and the inner surface of the rectangular block 504 are threadedly sleeved, as the screw rod 502 rotates, the rectangular block 504 will move with the connecting rod 405, so that the connecting rod 405 generates a thrust on the rotating rod 402, pushing the rotating rod 402 to rotate with the fixed rod 401 as the axis. At this time, the vertical rod 403 movably sleeved with the rotating rod 402 will move along the top of the first filter plate 6 with the scraper 404 under the push of the rotating rod 402, thereby pushing the solid pollutants on the top of the first filter plate 6 into the collection box 8, so as to achieve the cleaning of the fixed pollutants, thereby preventing the solid pollutants from accumulating and clogging the first filter plate 6 and affecting the filtration treatment of the wastewater.

[0059] Then the operator starts the first motor 12, so that the rotating shaft 13 drives the disc 14 to rotate. At this time, the top of the movable rod 15 hinged to the disc 14 will rotate together, so that the bottom end of the movable rod 15 generates a thrust on the top of the vertical rod 11, pushing the vertical rod 11 and the pressure block 10 to move downward along the inner surface of the collection box 8, thereby compressing the fixed pollutants and reducing their volume for subsequent processing.

[0060] Then the operator starts the second motor 16, so that the first round rod 17 drives the driving gear 19 to rotate. Since the driving gear 19 is meshed with the driven gear 22, as the driving gear 19 rotates, the driven gear 22 will drive the second round rod 20 to rotate in the opposite direction. The first stirring rod 18 and the second stirring rod 21 are respectively fixedly sleeved on the outer surfaces of the first round rod 17 and the second round rod 20 and are staggered. Therefore, under the joint action of the first round rod 17 and the second round rod 20, the first stirring rod 18 and the second stirring rod 21 will rotate in the opposite direction, thereby fully mixing the reagent and the wastewater, thereby improving the purification efficiency of the wastewater.

[0061] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations.
