A pressure block 82 is fixedly connected to the lower end of the rotating rod 81. A protrusion 83 is in contact with the lower end of the pressure block 82. The protrusion 83 is fixedly connected to the filter screen 6. A connecting rod 84 is fixedly connected to the lower end of another filter screen 6. A connecting seat 85 is slidably sleeved on the outer side of the connecting rod 84. The connecting seat 85 is fixedly connected to the cylinder 1. A first spring 86 is provided on the outer side of the connecting rod 84. One end of the first spring 86 is in contact with the filter screen 6, and the other end of the first spring 86 is fixedly connected to the connecting seat 85. By designing the first spring 86, the force of the first spring 86 can act on the filter screen 6. By designing the filtration mechanism 8, wastewater can be filtered and purified.
[0023] Please see Figure 1 , Figure 2 , Figure 4 The cleaning mechanism 9 includes a fixed rod 91. A fixed rod 91 is fixedly connected to the outer side of the rotating shaft 14. A scraper 92 is fixedly connected to the outer side of the fixed rod 91, and the scraper 92 contacts the inner wall of the cylinder 1.

[0024] The specific implementation process of this utility model is as follows: In use, wastewater is input into the cylinder 1 through the inlet 5. Then, under the action of multiple filter screens 6, the wastewater can be filtered in multiple stages to achieve filtration and purification of wastewater. During the filtration process, the output end of the motor 11 drives the first gear 12 to rotate. The first gear 12 drives the second gear 13 and the rotating shaft 14 to rotate. The rotating shaft 14 drives the rotating rod 81 and the pressure block 82 to rotate. The rotation of the pressure block 82 will squeeze the protrusion 83. The protrusion 83 will drive the filter screen 6 to move downward. The filter screen 6 drives the connecting rod 84 to slide along the connecting seat 85. The filter screen 6 will squeeze the first spring 86. When the pressure block 82 rotates and separates from the protrusion 83, the elastic action of the first spring 86 will give the filter screen 6 an upward counter-force, which can make the filter screen 6 vibrate, avoiding the filter screen 6 being blocked by particles and affecting the filtration effect. When the cover plate 4 is opened, the filter screen 6 can be directly taken out from the inside of the cylinder 1, which is convenient for the replacement of the filter screen 6.
[0025] When cleaning of the cylinder 1 is required, the rotation of the shaft 14 will also drive the fixed rod 91 and scraper 92 to rotate. The scraper 92 can rotate along the inner wall of the cylinder 1 to scrape and clean the inside of the equipment. At the same time, cleaning agent is introduced into the shaft 14 through the input pipe 99. After the cleaning agent enters the outlet 93, it will push the baffle 94 to move horizontally. The baffle 94 drives the guide rod 95 and the fixed block 98 to move. The fixed block 98 squeezes the second spring 97, which can separate the baffle 94 from the outlet 93. At this time, the cleaning agent will be sprayed into the cylinder 1 through the outlet 93. The scraping of the scraper 92 can improve the cleaning effect inside the equipment. In addition, the baffle 94 is installed inside the outlet 93 to prevent wastewater from flowing back into the shaft 14 and causing pollution.
