When the bracket 37 drives the paddle device 38 to rotate as a whole, the paddle substrate 381 is used to paddle the wastewater, thereby evenly spreading the wastewater. At the same time, the wastewater is impacted on the paddle device 38 when it falls, and the main blade 382 and the paddle substrate 381 are rotatably connected. At this time, the main blade 382 and the secondary blade 381 are connected. 83 will block part of the wastewater, and under the impact of the wastewater, the main blade 382 drives the secondary blade 383 to rotate and compresses the arc spring 384, so that the blocked part of the wastewater is spread again, which further helps to evenly scatter the wastewater and facilitate subsequent filtration. When the rotating shaft 32 rotates, the main scraper 391 will be driven to rotate through the curved connecting rod 392, so that the auxiliary scraper 393 also rotates together. At this time, the rotating main scraper 391 and the auxiliary scraper 393 can scrape the debris filtered by the conical filter screen 2 in time, reduce the accumulation of debris, and help to gather the debris. At the same time, the top of the support member 394 is rotatably connected to the bottom of the main scraper 391, and under the elastic force of the elastic member 395,The surface of the wiping rod 396 is fitted with the surface of the conical filter screen 2, and under continuous rotation, the wiping rod 396 wipes off the debris remaining on the surface of the conical filter screen 2, further performs self-cleaning, and makes full use of its own rotation to perform cleaning in various ways. Moreover, when the waste water is transported from the water inlet pipe 6 to the treatment tank 1, the impact of the liquid is utilized to make the force-bearing water receiving tray 53 receive the impact force, and the force-bearing area is increased, and the top end of the swing rod 51 is rotatably connected with the bottom of the conical filter screen 2. At this time, the swing rod 51 drives the force-bearing water receiving tray 53 and the knocking device 54 to rotate in the opposite direction, and causes the elastic tension strip 52 to be stretched. As the force-bearing water receiving tray 53 rotates, the force-bearing water receiving tray 53 reduces the impact of the waste water, and under the elastic tension strip 52, the force-bearing water receiving tray 53 is stretched. Under the elastic force of the force bar 52, the swing rod 51 drives the force receiving water tray 53 and the knocking device 54 to reset, and then hit the bottom of the conical filter 2, and the conical filter 2 will vibrate, so that the debris attached to the surface of the conical filter 2 falls off, and then self-cleaning is achieved again. At the same time, the weight of the counterweight impact block 544 is used to make the knocking head 541 hit the conical filter 2 under the drive of the swing rod 51. The heavy impact block 544 will knock the conical filter 2 again under the action of inertia, thereby increasing the vibration frequency of the conical filter 2, which is conducive to self-cleaning. The interaction between the structures is used, and the inertia is fully utilized to connect the structures together, which is safe and reliable, realizes multiple functions, and improves the performance.
