DEWATERED CAKE FORCE FEED DEVICE

PROBLEM TO BE SOLVED: To provide a dewatered cake force feed device having a uniaxial eccentric screw pump capable of transferring even a supe-viscous dewatered cake of the moisture content of 70% or less conventionally difficult to transfer by the uniaxial eccentric screw pump with high volume efficiency. SOLUTION: This dewatered cake force feed device has a uniaxial eccentric screw pump part. A rotational driving shaft 24 is arranged on the axis in the longitudinal direction in a feeder casing, and its both ends are rotatably supported by a bearing 25. Two sets of agitating blades 27 are installed at an interval in the longitudinal direction on the rotational driving shaft 24 by shifting a phase, and the respective sets of agitating blades 27 are formed as a structure of connecting a part between respective agitating parts 28 and the rotational driving shaft 24 by a support member 29 having an opening 29b by providing three or more of agitating parts 28 projecting to both sides in the longitudinal direction at an equal interval in the circumferential direction in a tip part in the radial direction.
