At the same time, since the annular screen 206 is constantly rotating, the impurities in the annular screen 206 can be better cleaned.

[0043] Embodiment 2: On the basis of Embodiment 1, please refer to Figures 8 - 10 , the adjusting mechanism 3 includes a sliding plate 301. The inner wall of the sliding plate 301 is movably connected with the moving device 103. Both sides of the sliding plate 301 are fixedly connected with a first connecting plate 302.

Both ends of the first communicating pipe 305 are fixedly connected with a communicating component 31. When the device performs self-cleaning on the filtering mechanism 2, the water inlet of the device will be switched, and before the switching is completed, the device will stop the entry of sewage. The moving device 103 drives the sliding plate 301 to move. The moving sliding plate 301 drives the first connecting plate 302 to move, and then drives the switching component 32 to move, changing the states of the communicating components 31 on both sides of the filtering component.

[0044] The communicating component 31 includes an outer shell three 311. The top of the base 1 is fixedly connected with the outer shell three 311. The outer wall of the outer shell three 311 is fixedly connected with an arc-shaped groove 312. One end of the arc-shaped groove 312 away from the outer shell three 311 is fixedly connected with the first round plate 203. The top of the outer shell three 311 is fixedly connected with a second communicating pipe 313. The inner wall of the second connecting pipe 304 is movably connected with the connecting column 2015. The impurities remaining in the communicating component 31 will be transported to the impurity storage box 104 through the second communicating pipe 313 and the outer shell three 311.

[0045] A sliding frame one 314 is fixedly connected to the top of the connecting pipe two 313. A connecting pipe three 315 is fixedly connected to the top of the sliding frame one 314. A sliding frame two 318 is fixedly connected to the top of the connecting pipe three 315. When the device is working, sewage will enter from the connecting pipe one 109 and be discharged into the filtering mechanism 2 through the connecting pipe one 305, the sliding frame two 318, the connecting pipe three 315, and the sliding frame one 314. A cylinder 316 is movably connected to the inner wall of the connecting pipe three 315. A push rod two 317 is fixedly connected to one end of the cylinder 316 away from the connecting pipe three 315. One end of the push rod two 317 away from the cylinder 316 is fixedly connected to the circular plate one 203. When this component conveys sewage, the push rod two 317 will drive the cylinder 316 to move forward. The protruding cylinder 316 can filter some larger impurities in the sewage, reducing the pressure on the subsequent annular screen 206 for filtering. When this component stops conveying sewage, the push rod two 317 will drive the cylinder 316 to move backward, causing the bottom of the impurities to lose support, and then the impurities will fall into the impurity storage box 104 through the connecting pipe two 313 and the outer shell three 311.

A sewage discharge hole 325 is formed in the outer wall of the sliding column two 324. A water passing hole two 326 is formed in the outer wall of the sliding column two 324. When the sliding plate 301 drives the connecting plate one 302 to move, the connecting plate three 321 also moves together. The moving connecting plate three 321 drives the sliding column one 322 and the sliding column two 324 to move together. When the connecting plate three 321 moves backward, the water passing hole one 323 on the sliding column one 322 and the water passing hole two 326 on the sliding column two 324 coincide with the connecting pipe three 315 to ensure the normal flow of sewage. When the connecting plate three 321 moves forward, the sliding column one 322 blocks the entry of sewage, and the sewage discharge hole 325 coincides with the connecting pipe three 315, so that the impurities can fall into the connecting pipe two 313 through the sewage discharge hole 325, facilitating the discharge of the impurities.
