[0004] 1. The inner diameter of the moving ring is smaller than the outer diameter of the screw shaft blades, and the moving ring always rubs against the screw shaft blades, especially under the action of strong sludge internal pressure during dehydration, this friction is like a file, constantly filing, greatly reducing the durability and usefulness of the

Abstract

The invention relates to the solid-liquid separating technology, in particular to a filter device belonging to the field of environmental protection sewage. The invention specifically discloses a novel screw type solid-liquid separating machine which comprises fixed ring, a movable ring and a screw shaft, wherein the screw shaft is provided with the fixed ring and the movable ring arranged in a staggered mode in the radial direction; the movable ring is connected with an eccentric shaft; and the screw shaft drives an eccentric shaft to rotate through gear transmission, or chain transmission, or belt transmission, and the eccentricity of the eccentric shaft drives the movable ring for to wander. The wandering of the filter body movable ring is the wandering generated by the eccentricity of the eccentric shaft, and the invention fundamentally solves the abrasion problem of the movable ring and a lamina of the screw shaft and greatly enhances durability and practicability of a separating device. The invention is suitable for large-sized, middle-sized and small-sized sewage treatment plants.

Description

technical field [0001] The invention relates to a solid-liquid separation technology, in particular to a filtering device in the field of environmental protection sewage. Background technique [0002] Chinese utility model patent CN2762865Y disclosed a laminated spiral filter on March 08, 2006, which includes a screw shaft, and a plurality of circular laminations are set outside the diameter of the blades of the screw shaft. The ring, the moving ring and the adjusting block are composed of multiple circular laminations. There is an adjusting block and a moving ring between every two fixed rings. The inner diameter of the fixed ring is larger than the outer diameter of the blade of the screw shaft, and the inner diameter of the moving ring is smaller than the screw shaft The outer diameter of the blades of the shaft and the inner diameter of the moving ring are arranged with notches larger than the outer diameter of the blades of the screw shaft. The screw shaft and the fixed...
