Problems solved by technology

[0005] 1. Due to the poor fluidity of high-concentration fiber raw materials, the feeding screw and the fixed grinding plate are concentric, and must first pass through the feeding area in the center of the grinding plate and have a certain gradient before entering the plane refining area for refining. In the crushing and deflaking area, the high-concentration fiber raw materials can pass through the crushing and deflaking area and enter the plane refining area completely relying on the strong pushing of the feeding screw. discus” solid material block and cannot enter the plane refining area; on the other hand, the strong pushing force of the feeding screw acts on the rotating disk, which incr

Embodiment Construction

[0010] The embodiments of the eccentric feeding high-consistency refiner of the present invention will be further described below in conjunction with the accompanying drawings.

[0011] In the eccentric feeding high-consistency refiner of the present invention, since the feed hole is provided with a larger eccentricity relative to the center of the rotary grinding plate, the feed hole is aligned with the refining tooth surface of the rotating grinding plate; the high-concentration fiber raw material Driven by the feeding screw, it directly enters between the fixed grinding plate and the rotating grinding plate, and the high-concentration fiber raw material is brought into the plane refining area by the grinding teeth on the rotating grinding plate, and the arc-shaped groove on the fixed grinding plate changes from deep to shallow It can make the bulky high-concentration fiber raw materials easily enter the plane refining zone without relying on the strong pushing of the feeding...

Abstract

A high-concentration pulp grinder with eccentric feeding inlet is composed of casing, front end cover, feeding screw, rotary and fixed grinding discs with grinding teeth on their opposite surfaces, grinding gap regulator, and drive unit. Its advantages are not blocking and long service life of mainshaft.

Description

(1) Technical field [0001] The invention relates to a high-consistency pulping and pulping equipment, in particular to an eccentric feed high-consistency mill capable of grinding various fiber materials such as wood chips and grass chips into pulp or refining and thermally dispersing high-consistency pulp. pulper. (2) Background technology [0002] Ordinary high-consistency refiners have a feed screw fixed in front of the front cover of the shell, and a fixed grinding disc is fixed behind the front cover and concentric with the feed screw. Feed hole for feed screw to penetrate. The shell is connected with the bearing box of the main shaft. The shaft end of the main shaft in the shell is fixed with a circular moving disc. The rotating disc is installed on the moving disc. A stuffing box or a mechanical seal is used between the shell and the main shaft. The grinding plate gap adjustment mechanism is used to adjust the gap between the rotating grinding plate and the fixed gri...
