摘要 |
An apparatus for treating a fibre suspension in a liquid to remove therefrom solid foreign particles. The apparatus has an inlet for receiving inflowing fibre suspension mixed with solid foreign particles; a first outlet for discharging part of the suspension liquid and said solid foreign particles; a screen positioned to define a filtering enclosure extending between said inlet and first outlet; a rotor disposed within said filtering enclosure for rotation therein to apply to the suspension fluidizing forces breaking up interlocked fibre flocs present therein and thereby fluidizing a part of said suspension to exit therefrom through said screen; and a second outlet communicating with the exterior of said screen to allow exit of fluidized suspension. The rotor has a plurality of radially extending blades supported by a central shaft, and the screen has a plurality of radially extending ribs inwardly directed to a predetermined clearance with said radially extending blades to thereby establish fluidizing forces acting upon the suspension. |
