Solid-liquid separation device

摘要

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.

主权项

1. A solid-liquid separation device comprising:
a plurality of fixed members and movable members movably disposed between adjacent fixed members of the plurality of fixed members; at least one 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 being rotationally driven about a center axis line, an object to be treated that has penetrated into a solid-liquid separation portion demarcated by the fixed members and the movable members being caused to move toward an outlet of the solid-liquid separation portion by rotation of the screw, and a filtrate separated from the object to be treated being discharged to the outside of the solid-liquid separation portion through filtrate discharge gaps between the fixed members and the movable members, the object to be treated having a reduced liquid content ratio being discharged from the outlet to the outside of the solid-liquid separation portion, at least one part of the movable members being movable to be synchronized with the driving of the screw through an eccentric mechanism, while penetrating closer to a center axis line of the screw than an outer circumferential edge of a blade of the screw, without coming into contact with the screw.
