Since the cross bar 1 33 and the cross bar 2 35 are respectively on both sides of the S-shaped shaft 32, when the cross bar 1 33 slides to the right When the water discharge pipe 39 is discharged, the horizontal bar 35 slides to the left, and the sliding directions of the two are opposite, that is, the sludge washed down by the water spray pipe 39 can be pushed by the scraper 36, so that the sludge can be discharged through the discharge pipe 4.

Excessive clogging of the filter screen 6 is achieved to separate sewage and sludge. Since the sludge falls down and mainly accumulates in the lower half of the filter screen 6, the scraper 20 only scrapes the lower half of the filter screen 6 back and forth. When the through hole inside the sphere 9 rotates to no longer intersect with the through hole inside the spherical shell 8, the water flow cannot enter the interior of the delivery pipe 14. Under the action of the spring 17, the spring 17 slides upward, and through the rotation of the sphere 9, the flow of water is blocked or opened, thereby achieving the reciprocating scraping work of the scraper 20.
