Pulp absorbing area: the filter plate immersed in the pulp while in operation produces a surface absorption of filter cake, with the action of capillarity and integrated with the vacuum pressure. The filtrate enters the distributing valve and drainage tank through filter plate.
Spraying zone: the filter cake receive spray washing after discharged from the slime hopper.
Drying zone: continuous dewatering for the filter cake is conducted with the action of the high vacuum force.
Discharging zone: the scraper will automatically discharge materials once entering the vacuum-free condition.
Back Flushing: the service water or filtrate enters the ceramic plate through distributing valve and cleaning the blocked manhole. Cleaning with ultrasonic and low-density acid after ceramic plate is used for one period to maintain the efficient service life of the ceramic plate.
