Claims

[Scope of Claim for Utility Model Registration] 1. A cylindrical furnace material having a sludge supply port and a cake discharge port, which has screw blades on its outer periphery inside the outer cylinder, and rotates a screw shaft whose inside can be heated with a heating medium. A screw press that is freely deployable and gradually reduces the gap formed between the outer cylinder and the screw shaft toward the cake discharge port, and discharges the sludge from the cake discharge port while compressing and dewatering the sludge by rotation of the screw shaft. In the type dehydrator, a cavity is formed inside the screw shaft and sealed, and a drive shaft is connected to one end of the cavity, and a support shaft is connected to the other end of the cavity. A screw press type dehydrator in which a heating medium can be introduced through the drive shaft or support shaft. 2. The dehydrator according to claim 1, wherein a drain pipe communicating with the outside is attached to the cavity inside the screw shaft. 3. The dehydrator according to claim 1 or 2, wherein a heating medium introduction part is provided on the cake discharge port side of the screw shaft, and a heating medium delivery part is provided on the sludge supply port side, respectively.
