Sludge dewatering machine stacked screw body mechanism capable of reducing wear rate of screw shaft

Abstract

The invention relates to the technical field of environmental protection, and discloses a sludge dewatering machine stacked screw body mechanism capable of reducing the wear rate of a spiral shaft. The stacked screw body mechanism comprises a main body, a fixed plate, a movable plate, a filter port and a spiral shaft, and arc-shaped plates are fixedly mounted on the two sides of the movable plate. Through the arrangement of the arc-shaped plates and a thread, when the movable plate drives the arc-shaped plates to synchronously rotate, the rotating arc-shaped plates can scrape sludge blocked between the movable plate and a fixed plate due to the movement of the movable plate, the sludge is prevented from blocking a filter opening and influencing the dewatering operation, then the thread guides the sludge on a scraper, and the sludge is enabled to enter the operating area of the spiral shaft to avoid secondary blockage of the sludge. Meanwhile, due to the arrangement of the thread, the contact area of the sludge driven by the spiral shaft and the movable plate is increased, the viscous force of the sludge and the movable plate is increased, the spiral shaft drives the movable plate to rotate synchronously through the viscous force, further the condition that the screw shaft and the movable plate move relatively, abrasion is generated, and dewatering operation is affected is avoided.

Description

technical field [0001] The invention relates to the technical field of environmental protection, in particular to a stacked screw mechanism of a sludge dewatering machine which reduces the wear rate of a screw shaft. Background technique [0002] The sludge dewatering machine is a kind of sludge treatment equipment that can dehydrate the sludge. There are many types of sludge dewatering machines, among which the stacked screw sludge dewatering machine is particularly outstanding. [0003] The existing screw-type sludge dewatering machine is composed of a fixed plate and a movable plate stacked on each other, and the filter body formed by the screw shaft passing through it is the main structure. The wheelbase of the screw shaft is gradually reduced, and the back pressure plate at the mud outlet The pressure provided, and then the sludge is squeezed and dehydrated. After that, the detached water is discharged from the filter seam formed by the relative sliding of the moving pl...
