脱水機。[Scope of Claim for Utility Model Registration] 1. An outer cylinder 3 of a cylindrical furnace material having a sludge supply port 1 and a cake discharge port 6 has screw blades 4 on the outer periphery, and the inside can be heated with heating fluid. The screw shaft 5 is rotatably arranged, and the gap formed by the outer cylinder 3, the screw shaft 5, and the screw blades 4 is sequentially reduced toward the cake discharger 6 side, and the screw shaft 5
In a screw press type dewatering machine that compresses and dehydrates sludge by rotating the cake and discharges it from the cake discharge port 6, the screw shaft 5 is connected to a front half 5a on the sludge supply port 1 side, at least a part of which is formed of furnace material. It is divided into a rear half 5b on the side of the cake discharge port 6, and the front half 5a is fixedly arranged.
The screw blade 4 located in the front half 5a is connected to the front half 5.
A screw press type dehydrator characterized in that it is separated from the rear part 5b and can be rotated by the rear part 5b. 2 The front half part 5a has the front half part 5 on the inside thereof and on the outside surface thereof.
(a) The dewatering device according to claim 1, which is a utility model registered and is equipped with a heated fluid introduction pipe that has a flexible blade for scraping off deposits on the inner surface and rotates integrally with the rear half portion 5b. Machine.
