Application:
It is used for pulp dewatering and the recovery of white water.
Design features:
It consists of feeding box, filter cell, core axis, bearing, spray pipe of filter disc, filter screen and broke pulp conveyer.
Multi-disc filter takes advantage of dewater leg vacuum to dewater. When the pulp enters the feeding box and spills over the filter plate, and then flows to the contrary direction of filter disc, the fluid level can be controlled by rotating speed. Fan-shaped filter board submerges in the pulp. Filter liquor flows into fan-shaped disc and core axis. The exchanged air discharges through the valve and the pipe connecting with the air. During the filtering of multi-disc filter, a few small and micro fibers from thick filter liquor through filter layer since there is a few fiber absorbed on the discs. With the continuously rotating, the filter bed will be thick and the fiber in filtrate will be further reduced so as to form extraclean filtrate. Therefore, the purpose of white water filtering and fiber recovery has been reached.
