スラッジ及び類似物の脱水装置
Document Type and Number:
Japanese Patent JP4629061
Kind Code:
B2
Abstract:
This sludge thickener includes a sludge chamber with a filter surface. This is connected to sludge inlets with equipment producing a hydrostatic pressure for filtration. The sludge chamber is formed by pressure plates, which can be moved to reduce the chamber volume, having reached the hydrostatic dewatering pressure, in order to exert additional mechanical dewatering pressure. There is also a pre-dewatering device containing filtration surfaces and connected to a continuous sludge supply, with which the hydrostatic filtration pressure generator is connected. The filtration surfaces can move relative to the sludge chamber, allowing extraction of the filter cake after opening the pressure plates
