Filter plant where belt movement is independently controlled of slippage etc. - has filter box above belt, and suction box to receive filtrate passing through stationary belt, and markings to check belt movement

摘要

Filter plant has a discontinuously operating filter belt (2), consisting of an endless strip of filter cloth passing over several deflection rolls (4). Above the belt is a filter box (6). Suction box (8) receives the filtrate passing through the stationary belt. Along at least one long side of the belt are several equidistant markings (9) to allow the movement of the belt to be checked. A sensor (10) aligned with the markings provides signals to a control system. ADVANTAGE - Belt movement can be controlled independent of slippage etc
