Fibre detaching apparatus with high shearing

Abstract

A high-shear fiber breaker for separating fiber beam and fiber fragment from paper stuff is provided. It contains shelf, dynamic units and multilevel operate units. Each unit contains helical delivery area in beck body and major work area. Helical delivery area contains constant screw stem on screw shaft. One end of constant screw stem connects with major work area. Beck body wall related to another end has a feed head. Major work area contains a series of vary screw stem on the square screw shaft. Vary screw stem arranges forward and reverse independent. Path with unloading valve for connecting with the next grade operating units is set on beck body in center of axial direction of major work area. A raw of filtration pore with filtrate receiver is set under the beck body wall in axial direction of vary screw stem.

Description

Technical field [0001] The invention relates to a fiber dissociation machine, in particular to a high-shear fiber dissociation machine. Background technique [0002] A certain amount of fiber bundles or fiber fragments remain in mechanical pulp, chemical mechanical pulp, and high kappa number chemical pulp, and the single fiber is relatively stiff (compared with low kappa number chemical pulp fiber), resulting in The paper surface has rough texture and low smoothness, and the appearance quality and printing effect are poor. If a disc mill is used to process the pulp to reduce the content of fiber bundles or fiber fragments, although it can have a certain effect, but the greater side effect is that the pulp is strongly affected by the beating, resulting in a large degree of pulp beating. Ascending, the cutting of fibers and the splitting of fibers are significant, which directly affects the subsequent process operations. Except for the disc mill, there is currently no other effect...

AI Technical Summary

Problems solved by technology

[0002] Due to mechanical pulp or chemomechanical pulp, high kappa number chemical pulp, a certain amount of fiber bundles or fiber fragments remain, and the single fiber is relatively stiff (compared with low kappa number chemical pulp fibers), resulting in The surface texture of the paper is rough, the smoothness is low, and the appearance quality and printing effect are poor

If the pulp is treated with a disc refiner to reduce the content of fiber bundles or fiber fragments, although it can achieve a certain effect, the greater side effect is that the pulp is strongly affected by the beating, resulting in a substantial increase in the beating degree of the pulp. The phenomenon of fiber cutting and segregation is obvious, which directly affects the subsequent process operation

There is currently no effective method of eliminating or substantially reducing fiber bundle or fiber fragment content other than disc refiners
