Description

Pulping machine for papermaking and pulping

Technical Field

The utility model relates to a papermaking technical field, in particular to fiberizer of papermaking slurrying usefulness.

Background

The paper making technology is one of four inventions in ancient China. The invention of paper greatly facilitates the storage and communication of information, and has epoch-making significance for promoting the development of world civilization. The raw material for making paper mainly is plant fibre, and in addition to three main components of cellulose, hemicellulose and lignin, the raw material also contains other components with small content, such as resin and ash, etc.. In addition, auxiliary components such as sodium sulfate are also included. In the manufacture of paper, the raw material is ground by a refiner, which is a machine that grinds the processed raw material into a pulp.

The pulp after digestion or mechanical disintegration, screening and bleaching cannot be used directly for papermaking. Because the fiber in the paper pulp lacks necessary flexibility, the bonding force between the fiber and the fiber is not ideal enough, and if the paper is made by the fiber, the paper is loose and porous, has rough surface and low strength, and cannot meet the use requirement. The grinding disc is the heart of the pulp grinder, directly generates acting forces such as shearing, crushing, stretching, friction and the like on the paper pulp fibers to change the fiber form, and meets the papermaking adaptability. The method comprises the steps of three-part papermaking and seven-part pulping, wherein the pulping is to treat fibers in paper pulp by using a mechanical action method of grinding plates and insections so as to untwist, properly cut and fibrillate the fibers; more importantly, the fibers absorb water and swell during pulping, so that the fibers have higher elasticity and plasticity, and meet the production requirements of a paper machine, so that the produced paper can reach the expected quality index. The design of the grinding disc always follows the theory of specific blade edge load (SEL), and research practice cases of China Nantong Huayan grinding disc research center, organization such as Oldenlinederritz and the like show that the factors such as specific surface load, rheological effect and the like need to be fully considered. The specific knife edge load theory describes and characterizes the beating characteristics in terms of the effective load of impact shear flocked fibers in the unit length of the intersection of the rotating knife teeth and the fixed knife teeth of the refiner.

Current refiners, like the patent of publication "CN 206512515U", grind through multiple multi-stage refining, which is inefficient, complex, and costly, and multiple refining mechanisms generate multiple times of noise.
