APPARATUS FOR REMOISTENING FILTER CAKE IN A DEWATERING MACHINE

摘要

Disclosed are methods and apparatus for rinsing soluble materials from the filter cake formed in a double belt press. The belts with the filter cake therebetween are suspended between two spaced apart rollers to relieve pressure on the filter cake and the filter cake is simultaneously exposed to a rinse medium. Pressure is thereafter re-applied to the filter cake to extract the rinse medium therefrom.
