Environment-friendly papermaking process

Abstract

The invention discloses an environment-friendly papermaking process which comprises the following steps: S1, uniform mixing: injecting paper pulp and mixed water into a sedimentation tank, loosening a vertical round rod, so as to insert the vertical round rod into the paper pulp, and uniformly mixing the paper pulp when the vertical round rod moves forwards along with a guide block, so as to enable printing ink and particle impurities to be capable of normally floating and sinking; and S2, separation: retightening the vertical round rod at the top of the vertical rod. According to the invention, a hydraulic telescopic rod is used for driving a connecting plate and a paper pulp filtering plate to descend, so that the ink filtering plate descends to the position below the liquid level, meanwhile, a driving motor drives a lead screw to rotate, a guide block moves forwards along with a moving block, a printing ink filter plate can filter and remove floating printing ink and grease substances generated when waste paper pulp is soaked, and the paper pulp pressing inclined plate can press the paper pulp floating on the surface downwards when moving forwards, so that the paper pulp cannot be adhered to the printing ink filter plate, and soaking water can smoothly penetrate through the water permeable holes.

Description

Technical field [0001] Technical Field The present invention relates to paper making equipment, particularly to an environmentally friendly papermaking process. Background technique [0002] Paper industry is an important basic raw material industry of the national economy, consumption of paper and paperboard has become a measure of the level and degree of civilization important symbol of national modernization, the use of waste paper as raw material, pulp and paper process, not only can save natural fiber resources, repeat use of waste material, can reduce the pollution load of the papermaking process, protection of the natural environment, fully embodies the concept of energy saving, crushed waste paper, soaking, stir, precipitation, separation step, the adhesion to paper and pulp removing the attached ink particles, the pulp extraction for clean recycling subsequent sheets; [0003] However, at present the paper soaking and precipitation process, can not be accurately separate...

AI Technical Summary

Problems solved by technology

[0004] The present invention provides an environment-friendly papermaking process, which can effectively solve the problem that during the soaking and sedimentation process of the paper proposed in the above-mentioned background technology, it is impossible to accurately separate the pulp from impurities such as ink and particles, resulting in impurities such as ink remaining in the extracted pulp. , making the quality of the remanufactured paper decline
