Title:
SOLID-LIQUID SEPARATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2012/101980
Kind Code:
A1
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 moreover 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. Following the rotation of the screw, an object to be treated that has penetrated into a solid-liquid separation portion demarcated by the fixed members and the movable members is caused to move toward an outlet of the solid-liquid separation portion, a filtrate separated from the object is discharged to the outside of the solid-liquid separation portion through filtrate discharge gaps between the fixed members and the movable members, and the object that has a reduced liquid content ratio is discharged from the outlet to the outside of the solid-liquid separation portion. In order to increase significantly a dewatering ratio of the object, 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.
