Claims

[Scope of utility model registration request]

A screw shaft having screw blades on the outer periphery and the inside of which can be heated with steam 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 and the screw shaft and a screw press type dehydrator in which the annular gap volume formed by the screw blades is gradually reduced toward the cake discharge port side, and the sludge is compressed and dehydrated by rotation of the screw shaft and discharged from the cake discharge port; A cylindrical body is provided concentrically in the rear half of the outer cylinder to form an annular chamber, a steam ejector is attached to the steam inlet to the screw shaft, and an exhaust pipe is connected between the suction port of the steam ejector and the annular chamber. A screw press type dehydrator configured to communicate with each other through a screw press and to reduce the pressure inside the annular chamber with the steam ejector.
