Abstract

The invention discloses a novel gravity multi-disc thickener. The thickener comprises a tank body and a hollow main shaft mounted on the tank body, and a plurality of filter discs are arranged on thehollow main shaft; an upper cover is arranged above the tank body in a covering manner, and a spraying device is arranged at the upper cover; and a feeding hopper and a discharging hopper are oppositely arranged on two sides of the hollow main shaft of the tank body; and filtrate outlet boxes are respectively arranged at two axial ends of the hollow main shaft. Each filter disc comprises a plurality of fan-shaped filter frames, and filter screens cover the fan-shaped filter frames; each fan-shaped filter frame comprises a fan-shaped frame consisting of an outer arc plate, an inner arc plate and two support rods arranged along the radial direction, grid plates are symmetrically arranged on two axial sides of the fan-shaped frame respectively, and filter screens cover the grid plates; the axial width of the outer arc plate is smaller than that of the inner protection plate, so that the two grid plates get close to the center in the direction from the inner arc plate to the outer arc plate, and a frustum-shaped section structure with a small outer end and a large inner end is formed. The thickener is compact in structure, efficient and reliable in dehydration effect, large in effective dehydration area and easy to operate.

Description

technical field [0001] The invention relates to the technical field of gravity multi-disc thickeners, in particular to a novel gravity multi-disc thickener. Background technique [0002] In the paper production line, the gravity disc thickener is used for the washing and thickening of low consistency pulp. The gravity multi-disk thickener can achieve the largest dehydration area under the limited installation space. The hollow main shaft of the gravity disc concentrator is composed of a number of filter discs, each filter disc includes a number of fan-shaped filter frames, the fan-shaped filter frames are covered with filter screens, and the fan-shaped filter frames are fixed on the main shaft with screws. There are several through holes, which communicate with a fan-shaped filter frame on each filter disc respectively, and the hollow main shaft and the root of the fan-shaped filter frame are sealed with special rubber pads. [0003] When working, the slurry is pumped to t...
