Patent ID: 8672141

Claim:
A solid-liquid separating system comprising: a first plate group including a plurality of plates which are piled with predetermined spaces in a direction orthogonal to a longitudinal direction, and extend between an inlet and an outlet for sludge and have a single-piece structure; and a second plate group including a plurality of plates which are engaged with the plates of the first plate group and have a single-piece structure, wherein the first and second plate groups constitute a filter, and wherein a press unit presses the sludge toward upper surfaces of the plates of the first and second plate groups at the outlet, either the first plate group or the second plate group has plates thereof thickened in the direction orthogonal to the longitudinal direction at the outlet, and gaps between the plates thickened at the outlet are narrower than gaps of the plates at the inlet, and wherein the sludge is conveyed from the inlet to the outlet as the upper surfaces of the plates of the first and second plate groups are alternately moved up and down in response to a parallel movement of the first plate group and/or the second plate group.
