Technical Field
The utility model relates to a pulping and papermaking waste paper regeneration preparation field, in particular to stator of fluffer of handling wet strength waste paper fluffs pinion rack.
Background
The wet strength agent is widely applied to the paper industry, can effectively improve the wet strength of paper, and is commonly used in banknote paper, decorative base paper, hand towel paper, adhesive tape base paper, photographic base paper, thermal transfer paper, filter paper, tea bag paper, wallpaper, ground blueprint, seedling raising paper, fruit bag paper, food packaging paper, various special papers needing the wet strength and the like. Non-wet strength paper loses strength within a few seconds after being saturated with water. However, wet-strength dry broke and broke other than "temporary" wet-strength paper are difficult to break down and defiber, often requiring application of chemicals, high temperatures, and relatively severe mechanical forces to defiber into pulp. Some waste paper with high glue content and high wet strength uses water-resistant auxiliary agent, which hinders water permeation, and is difficult to be broken in the repulping, defibering and regenerating process, and the defibering effect is not ideal. At present, the defibering machine is adopted to defiber wet-strength waste paper as an indispensable measure.
The fluffer is composed of a movable gear ring group and a fixed gear ring group which are oppositely configured; during the defibering operation, wet strength waste paper raw materials flow in from the central opening of the static gear ring group, and flow to the outer peripheral direction along the gap between the movable gear ring and the static gear ring while being defibered. At present, a stator defibering toothed plate of a publicly known defibering machine for processing wet-strength waste paper is mainly of a labyrinth structure, the toothed plate structures are discontinuous projections such as trapezoids or triangles, and the like, and when the rotor defibering toothed plate works, the contact surfaces of the rotor defibering toothed plate and the stator defibering toothed plate are meshed and non-planar contact; when the movable gear ring rotates, the movable gear ring and the fixed gear ring form a meshing shape and move relatively, and wet-strength waste paper raw materials entering between the two gear rings are defibered and separated; at this time, because wet-strength waste paper raw materials flow to the periphery in a small gap, the tooth sheets are extruded in a centrifugal direction, the tooth sheets are deformed outwards and even damaged, the gap between two rings is smaller, and even adjacent outer ring tooth sheets are damaged, so that faults can be caused, and the operation is stopped. In addition, the defibering toothed plates often generate larger centrifugal pump output in high-speed operation, so that part of wet-strength waste paper raw materials are thrown out without being fully treated, raw pulp is generated, uniformity and binding force are influenced, the gaps between the meshed toothed sheets of the rotor defibering toothed plates and the stator defibering toothed plates are enlarged, the defibering effect is poor, and the defibering efficiency is lowered; and therefore when needing to improve and dredge the effect, must reduce the clearance that rotor dredged the pinion rack and stator dredged the pinion rack again, the meshing form tooth piece still at this moment is damaged very easily, still can reduce the rate of appearing and dredge the life of pinion rack, influences normal production. The prior art can not well meet the treatment requirement of wet-strength waste paper.
