ARRANGEMENT IN A PRESSURE SCREEN FOR SEPARATING IMPURITIES FROM A FIBRE SUSPENSION FED INTO THE SCREEN |
摘要 |
Arrangement in a pressure screen for separating impurities from a fibre suspension fed into the screen. The upper portion of the pressure screen comprises an upwardly tapering inlet chamber (6) into which the fibre suspension is fed through a supply conduit (4) tangentially with respect to the inlet chamber (6). The supply conduit (6) further comprises a control plate (5) which prevents fibre suspension already passed around the inlet chamber from immediately mixing with an incoming fibre suspension flow, and passes it into a central opening in a chunk collar (10) positioned centrally in the inlet chamber (6). The chunk collar (10) is connected to the ends of rotor foils (11) to rotate with them. |
