[0022] In this embodiment: the sewage that needs to be circulated and filtered can be discharged into the interior of the circulation box 1 through the water inlet pipe 2. The sewage will contact the upper surface of the filter 505 in the upper cavity, and the filter 505 will filter the impurities in the sewage. After a period of use, the flushing pump 4 can be started. The flushing pump 4 will provide an upward pulse-like impact water flow. The water flow impacts the lower end of the filter 505. During the flushing process, the impact force of the water flow simultaneously drives the movable block 502 to move upward, so that the stop block 503 on the movable block 502 moves upward synchronously, so that the stop block 503 hits the bottom of the filter 505, providing a vibration force for the filter 505, which can make the impurities accumulated on the filter 505 move along the inclined direction of the filter 505 until it falls from the gap between the lower end of the filter 505 and the circulation box 1 when the filter 505 is intermittently lifted, thereby avoiding the situation where the filtration efficiency of the filter 505 decreases due to the accumulation of impurities.

[0023] Please refer to Figure 1-Figure 3 There are multiple movable blocks 502, which are evenly distributed on the outer wall of the transmission rod 504.
