Abstract
PURPOSE: To freeze, thaw and dehydrate sludge by vertically placing two endless belts at both edges of a driving horizontal endless belt. putting sludge into the resulting recess, and freezing the sludge through the vertical belts.
CONSTITUTION: Rubber belt 1 and steel belts 2, 3 are allowed to contact to each other by pressing, and sludge 9 is put into the resulting recess. By circulating brine 8 cooled with a cooler in brine passes 4a, 4b while driving belts 1, 2, 3, sludge 9 is cooled from two sides through steel belts 2, 3, gradually frozen, and thoroughly frozen until it reaches one end. This thoroughly frozen sludge reaches a warm water supply section, where the pillar-shaped sludge leaves this apparatus. Thus, sludge is dehydrated efficiently with such a simple apparatus.
