At this time, the baffle 209 is driven upward by the push rod 1 208 to open the water outlet 206. At this time, the sewage will flow into the partition 205 from the water outlet 206, and the sewage in the partition 205 will be sent to the impurity removal device 101 through the circulation pipe 103 for re-filtration and disinfection. The inner wall of the shell 201 is fixedly connected with the screen 207, the outer wall of the partition 205 is fixedly connected to the screen 207, the outer wall of the partition 1 203 is fixedly connected to the screen 207, the bottom of the shell 201 is fixedly connected with a pumping device 2010, the outer wall of the pumping device 2010 is fixedly connected with a connecting pipe 2011, the inner wall of the shell 201 is fixedly connected with a sealing ring 2012, the inner wall of the shell 201 is fixedly connected with a detection component 21, and the inner wall of the shell 201 is fixedly connected with a pushing component 22.

[0023] The working principle of this embodiment is: when the equipment is working, the sewage first enters the impurity removal equipment, the sewage after impurity removal is transported to the disinfection device 104 through the connecting pipe 102, the disinfected sewage will be transported to the filtering mechanism 2, and after the sewage is filtered through the screen 207, the treated sewage is discharged from the equipment through the outlet pipe 202.

[0024] Example 2: Based on Example 1, please refer to Figure 6 The detection component 21 includes a ramp plate 211, the bottom of the ramp plate 211 is fixedly connected to the shell 201, a groove 212 is provided on the top of the ramp plate 211, a roller 213 is provided on the top of the ramp plate 211, one end of the roller 213 is rotatably connected to the shell 201 through a bearing, and the end of the roller 213 away from the shell 201 is rotatably connected to the partition 203 through a bearing, the inner wall of the ramp plate 211 is fixedly connected to a push rod 214, the top of the push rod 214 is fixedly connected to a lifting plate 215, and the outer wall of the lifting plate 215 is movably connected to the groove 212.

[0025] The working principle of this embodiment is as follows: when the equipment filters sewage, the filtered sewage will flow onto the ramp plate 211. At this time, the sewage will first flow backward along the ramp plate 211 to fill the space between the ramp plate 211 and the shell 201 with water, so as to facilitate the subsequent cleaning of the screen 207.

Before the push rod 214 pushes up the lifting plate 215, if the water flow cannot fill the groove 212 and drive the roller 213 to rotate, it means that the screen 207 on this side needs to be cleaned, and then the disinfection device 104 will transport sewage to the other side. The side where the screen 207 needs to be cleaned starts the pushing component 22 and the pumping device 2010 to clean the screen 207.

[0026] Example 3: Based on Example 1, please refer to Figure 7-Figure 9 The pushing component 22 includes a push rod 3 222, the inner wall of the outer shell 201 is fixedly connected to the push rod 3 222, the end of the push rod 3 222 away from the outer shell 201 is fixedly connected to the pushing seat 221, the interior of the pushing seat 221 is fixedly connected with an arc tube 223, the arc tube 223 penetrates the pushing seat 221 and extends to the top of the pushing seat 221, the front end of the pushing seat 221 is fixedly connected with a connecting plate 1 225, and the end of the connecting plate 1 225 away from the pushing seat 221 is provided with a slide groove 226, and the inner wall of the outer shell 201 is fixedly connected with the lifting component 23.

[0027] The lifting assembly 23 includes a connecting plate 231, the inner wall of the outer shell 201 is fixedly connected to the connecting plate 231, the inner wall of the connecting plate 231 is fixedly connected to an annular plate 232, the inner wall of the annular plate 232 is rotatably connected to an eccentric plate 233 through a bearing, the outer wall of the eccentric plate 233 is fixedly connected to a movable column 234, the outer wall of the movable column 234 is movably connected to the slide groove 226, the top of the connecting plate 231 is fixedly connected to an annular plate 235, the outer wall of the annular plate 235 is fixedly connected to a sliding plate 236, the inner wall of the sliding plate 236 is movably connected to a sliding column 237, and the top of the sliding column 237 is fixedly connected to a right-angle plate 238.

[0028] The working principle of this embodiment is as follows: when the screen 207 needs to be cleaned, the push rod 3 222 is activated to drive the push seat 221 to move forward, and the moving push seat 221 drives the arc tube 223 to move forward, so that the top of the arc tube 223 is no longer blocked by the partition 205. When the push plate moves forward, it drives the connecting plate 1 225 to move forward. The connecting plate 1 225 that moves forward drives the eccentric plate 233 to rotate through the movable column 234 and the slide groove 226. Lift the right-angle plate, and the bend of the right-angle plate will fit with the bottom of the protruding plate 224. After completing the above operations, start the pumping device 2010, and allow the water to flow through the connecting pipe 2011 and the arc pipe 223 to the bottom of the screen 207, so that the water flow can flush the screen 207 from the bottom, so that the debris above the screen 207 can be easily washed away. At this time, the sewage with impurities above the screen 207 will be discharged through the outlet 206 and the next cycle will be carried out.
