The driving motor 61 drives the first reciprocating screw 62 to rotate, and drives the other first reciprocating screw 62 to rotate under the transmission of the first sprocket 63 and the tooth chain. As the first reciprocating screw 62 rotates, the threaded sleeve 64 moves back and forth under the action of the thread, thereby driving the scraper 66 to move on the upper surface of the filter plate 7 under the action of the connecting rod 65.

The worm gear 82 is meshed with the worm 81, and a movable sleeve 810 is threadedly installed on the outer surface of the second reciprocating screw 88. A scraper ring 89 is fixedly installed on one end of the movable sleeve 810, and the outer surface of the scraper ring 89 is in contact with the inner wall of the processing box 1.

[0032] The specific implementation method is as follows: the first reciprocating screw 62 will also drive the second sprocket 83 to rotate when the rotating rod is rotated, and the worm 81 will be driven to rotate under the action of the tooth chain. At this time, the worm 81 will drive the fixed rod 84 to rotate and drive the bevel gear 85 to rotate. Under the engagement of the bevel gear 85, the rotating rod 86 will be driven to rotate. The rotating rod 86 will drive the stirring rod 87 to stir the filtered wastewater in the treatment box 1, thereby mixing the disinfectant powder and the wastewater evenly. When the worm 81 rotates, it will drive the second reciprocating screw 88 to rotate under the action of the worm wheel 82.

The scraper ring 89 cleans the inner wall of the treatment box 1 and waits until the wastewater and the disinfectant powder are fully mixed and discharged through the drain pipe 5.

[0033] Working principle: wastewater is injected into the treatment box 1 through the water inlet 2, and the two filter plates 7 will filter the wastewater twice and then store it at the bottom of the treatment box 1. Then the disinfectant powder is injected into the filtered wastewater through the feeding bucket 3, and the driving motor 61 drives the first reciprocating screw 62 to rotate, and drives another first reciprocating screw 62 to rotate under the transmission of the first sprocket 63 and the tooth chain. As the first reciprocating screw 62 rotates, the threaded sleeve 64 will move back and forth under the action of the thread, thereby driving the scraper 66 to move on the upper surface of the filter plate 7 under the action of the connecting rod 65. At this time, the scraper 66 will scrape the filtered impurities into the collection frame 4, and the water in the collection frame 4 will fall back into the treatment box 1 through the filter net. When the connecting rod 65 moves, it will drive the fixed plate 67 to move synchronously, and the fixed plate 67 will drive the knocking rod 610 to move on the lower surface of the positioning plate 611. Under the action of the top block 612, the knocking rod 610 is connected to the spring 68 and the mounting ring 69. The scraper 66 that is impacted will drive the filter plate 7 to vibrate synchronously. As the filter plate 7 vibrates, the impurities in the filter hole will be shaken out. The first reciprocating screw 62 will also drive the second sprocket 83 to rotate when the rotating rod is rotated. Under the action of the tooth chain, the worm 81 will be driven to rotate. At this time, the worm 81 will drive the fixed rod 84 to rotate and drive the bevel gear 85 to rotate. Under the meshing of the bevel gear 85, the rotating rod 86 will be driven to rotate. The rotating rod 86 will drive the stirring rod 87 to stir the filtered waste water in the treatment box 1, thereby mixing the disinfectant powder and the waste water evenly. When the worm 81 rotates, the second reciprocating screw 88 will be driven to rotate under the action of the worm gear 82. Under the action of the thread, the moving sleeve 810 will drive the scraper ring 89 to move up and down in the treatment box 1. The scraper ring 89 cleans the inner wall of the treatment box 1 and waits until the waste water and the disinfectant powder are fully mixed. Discharge through the drain pipe 5.
