ープレス型脱水機。A screw shaft having screw blades on the outer periphery and the inside of which can be heated with steam is rotatably arranged in the outer cylinder of a cylindrical door material having a sludge supply port and a cake discharge port, and
A screw press that sequentially reduces the annular gap volume formed by the outer cylinder, screw shaft, and screw blade toward the cake discharge port, and discharges the sludge from the cake discharge port while dewatering the sludge by pressure friction by rotation of the screw shaft. In the type dehydrator, a support plate is spirally wound inside the screw shaft in a direction opposite to the screw blades, and the pitch thereof becomes smaller as it approaches the sludge supply port side, and further the support plate is wound around the cake in the screw shaft. A steam inlet is provided on the discharge port side, and a steam drain is provided on the sludge supply port side. - A screw press type dehydrator characterized by having a discharge port.
