A screw shaft having screw blades on the outer periphery is rotatably provided in an outer cylinder of a cylindrical furnace material having a sludge supply port and a cake discharge port, and the outer cylinder, screw shaft and In a screw press type dewatering machine, the gap formed by the screw blades is gradually reduced toward the cake discharge port, and the sludge is compressed and dehydrated by rotation of the screw shaft and discharged from the cake discharge port. In addition to forming the sludge and the furnace material,
A screw press type dehydrator characterized in that a rake is movably disposed so as to be able to scrape off sludge concentrate adhering to the inner surface of the sludge hopper. 2. The dehydrator according to claim 1, wherein a vertical rotating shaft is disposed within the sludge hopper, and the rake is attached to the vertical rotating shaft. 3. The height of the outer edge of the screw blade is gradually increased from the sludge supply port side to the cake discharge port side at the installation position of the sludge hopper, and the height of the outer edge of the screw blade in this part is brought into contact with the screw shaft and driven. 2. The dewatering machine according to claim 1, which is a registered utility model, wherein a cam device is constructed by providing a driven body for moving the rake, and the rake is attached to the driven body to enable vertical and reciprocating movement. 4. The dehydrator according to claim 2 or 3, wherein the screw shaft is provided with a flow path for a heating medium therein.
