It is opened or closed according to practical operation situation.10 side wall of cylinder be connected with the water outlet port 16 being connected with outflow lumen room 13 and
Backwash water inlet port 17, similarly, water outlet port 16 and backwash water inlet port 17 also share the same pipeline, are respectively equipped with
Control valve can be opened or closed according to the actual operation.
When sewage solid detaches, sewage flows into the chamber 12 that becomes a mandarin through the port 14 that intakes, and from becoming a mandarin, chamber 12 passes through annular filter
Net 11, the sundries in sewage is trapped on annular filter screen 11, to realize the separation of solid and liquid of sewage.
Wherein, the chamber 12 that becomes a mandarin be equipped with rotating brush 18, rotating brush 18 by motor drive rotate, 10 top of cylinder be connected with
The blowdown port 19 that the chamber 12 that becomes a mandarin is connected, when needing to clean annular filter screen 11, rotating brush 18 can scrub annular
The sundries gathered on strainer 11, carrying the sewage of sundries can discharge through the blowdown port 19 at top.
When needing thoroughly to clean annular filter screen 11, water inlet port 14 and water outlet port 16 are closed, opens recoil
It washes into water port 17 and sewage backwash port 15, backwashing water backward erosion annular filter screen 11, it will be miscellaneous on annular filter screen 11
Object develops, and is discharged through sewage backwash port 15, meanwhile, when being backwashed, the also synchronization action brush of rotating brush 18
Annular filter screen 11 is washed, the two collective effect greatly improves backwash effect.
It intakes on port 14, water outlet port 16, backwash water inlet port 17, sewage backwash port 15 and blowdown port 19
Each control valve its working condition is controlled according to actual motion by controller (not shown), for example, when recoiling
When washing, control water inlet port 14, water outlet port 16 are closed, and open simultaneously backwash water inlet port 17, sewage backwash port 15.
Preferably, the pressure difference transmitter being electrically connected with controller is equipped between water inlet port 14 and water outlet port 16
20, pressure difference transmitter 20 can detect the filtration pressure difference between water inlet port 14 and water outlet port 16, when filtration pressure difference is larger,
And when reaching default value, controller control carries out backsurging operation, is cleaned to annular filter screen 11.
Preferably, rotating brush 18 is made of drive shaft and setting in the radially-protruding bristle of drive shaft, the diameter of bristle
