Abstract
PURPOSE: To efficiently dewater water-retaining sludge, by charging the water-retaining sludge onto a belt conveyer to form a sludge strip, gradually cooling the surface of the sludge strip during its carriage to form frost columns, and removing them.
CONSTITUTION: Sludge 7, having a water-retaining rate of 75W85% for instance, changed into a hopper 6 is quantitaively charged onto a belt 5 through the bottom of the hopper 6, to form a continuous sludge strip having a fixed thichkness on the belt 5. The sludge is carried into a freezing chamber 20 by the belt 5, where the sludge is freezed during its passage. According to this treatment, retained water comes out on the surface of the sludge, freezes as frost columns 8 and adheres onto the surface. Thereafter, the frost columns 8 are stripped by a cutter 12, and ice pieces 11 are discharged from a shoot 9. The dewatered sludge 10 is dropped from the end of the belt 5 and recovered.
