Abstract
PURPOSE: To dehydrate sludge effectively by effecting continuously a freezing-and- melting process for the condensed sludge accumulated on a belt running around a cooling drum and a heating drum.
CONSTITUTION: In case sludge is accumulated in an accumulating tank 6 and running filtrating cloth 8 is run through a depressurized chamber 7 within the tank 6, the condensed and dehydrated sludge is laminated on the surface of the filtrating cloth 8. Then the condensed sludge is pinched between the cloth 8 and a transporting belt 9 and is run around outer periphery of a cooling drum 2 maintained at low temperature by a refrigerator 1, and thereby the sludge freeze perfectly. When the frozen sludge is separated from the cooling drum 2 at a point A and is run around outer periphery of a heating drum 4 maintained at high temperature, the sludge melt perfectly. The sludge, thereafter, is separated from the heating drum 2 at a point B and is dehydrated by means of a dehydrating device 13, then, is scraped down by a scraper 14, and thus, is discharged out of the device.
