PROBLEM TO BE SOLVED: To provide a dehydration apparatus where structure is not complicated, the miniaturization of the whole and high pressure filtering are possible, and production cost can be reduced. SOLUTION: The dehydration apparatus is composed of: cylindrical casing 1 in which the center of the upper part is provided with a slurry charge port 4, and further, the front and rear edges are opened; a cover body 2 installed so as to be freely reciprocated to the front and the rear to the front edge port 1a of the casing 1 in such a manner that the front edge port 1a is opened and closed so as to be a watertight shape; and a piston 3 formed so as to be a columnar shape longer than the casing, freely slidable inside the casing 1 so as to be a watertight shape, and inserted from the rear edge port 1b of the casing 1 in such a manner that the tip can be reciprocated between the rear position of the slurry charge port 4 and the front position of the front edge port 1a. The cover body 2 and the piston 3 are provided with filtered water exhaust paths 6, 10 piercing to the thickness direction. COPYRIGHT: (C)2009,JPO&INPIT
