Slurry enters the first cavity by inlet pipe 9, from the uniform inflow screening areas of circumferencial direction.Rotor 4
The rotation of rotary blade 401 makes to generate positive pressure pulse and underbalance pulse on 3 surface of screen cylinder, and cooperation pumps the pressure effect that slurry generates,
Seam or hole of the qualified fiber by screen cylinder 3 in slurry are flowed out from grout outlet 10.It is attached to 3 surface of screen cylinder not over screening
Fiber and the underbalance pulse that is generated by rotary blade 401 of impurity clean.It can not enter the 4th chamber by the slurry of screening in slurry
Body gives next section of equipment processing by the discharge of scum pipe 11.
By the way that the third cavity of the rotor cone cylinder 403 and back taper of taper is arranged, make slurry first from the cone to narrow slowly
Shape flow path supplies slurry, and slurry is discharged from slowly open cone-shaped runner.As a result, all impartial to any position of screen frame
Low supply slurry, and all passed through resistance by identical in any position slurry.In addition, the entrance in screen cylinder 3 is set as overflow
Structure, the i.e. upper surface of conical shell 202 are higher than the lower surface of inlet pipe 9, make full direction uniform inflow of the slurry from screen cylinder 3
While, third cavity is also gathered from week by the slurry of screen cylinder 3, is flowed out through grout outlet 10.Fail to pass through in entrance side
The slurry of screening is moved along screen cylinder 3 towards scum pipe 11, and with the gradual accumulation of impurity in slurry, slurry concentration becomes larger.It is this
Situation is easy that 3 surface of screen cylinder is promoted to wear.It, can be fast but since slurry is flowed in the cone-shaped flow path to narrow slowly
Speed is discharged from 11 side of scum pipe, to reduce the abrasion of screen cylinder 3.
