Patent ID: 8596195

Claim:
A sludge dehydrating apparatus, comprising: a cylinder formed by alternately placing fixed disks and movable disks one after another with gaps defined between the plates, with at least two protrusions provided on a circumferential outer edge of each of the fixed disks and movable disks; compression means provided along a center axis of the cylinder, the compression unit receiving power from a drive source and moving and compressing sludge so that water is removed from the sludge through the gaps; a plurality of rotating rods inserted into insert holes formed in the protrusions of the movable disk so that the movable disks are connected to each other in a longitudinal direction of the cylinder by the rotating rods; and a pair of rotation guide units provided on respective opposite ends of the rotating rods, the pair of rotation guide units receiving power from a drive source and rotating the rotating rods at a same time so that the movable disks are reciprocating-rotated with respect to the fixed disks, wherein the drive source of the rotation guide units comprises a pair of motors provided on respective first sides of the rotation guide units, the pair of motors providing power to the pair of rotation guide units at a same time so that the movable disks are reciprocating-rotated with respect to the fixed disks by the rotating rods.
