Abstract
A solid-liquid separation device includes a plurality of fixed members and movable members that are movably disposed between the adjacent fixed members, and a screw extending through the fixed members and the movable members in a state where the screw is not in contact with the fixed members and the movable members. The screw is rotationally driven about a center axis line thereof. A filtrate separated from an object is discharged to the outside of the solid-liquid separation portion through filtrate discharge gaps, and the object that has a reduced liquid content ratio is discharged from the outlet to the outside. In order to increase significantly a dewatering ratio, the movable members are formed to move while penetrating closer to the center axis line of the screw than an outer circumferential edge of the blade of the screw, without coming into contact with the screw.
