Efficient, clean and damage-free repulping and deinking system based on waste paper and operation process of efficient, clean and damage-free repulping and deinking system

Abstract

The system comprises a tank body, a roller is rotationally connected to the middle of an inner cavity of the tank body, a defoaming mechanism is arranged at the liquid level position of an inner cavity of the roller, and the defoaming mechanism comprises a defoaming component connecting plate; the defoaming component connecting plate is fixedly connected with the upper portion of the roller, and the rear side of the defoaming component connecting plate is fixedly connected with an arc-shaped defoaming scraping plate. According to the efficient, clean and damage-free repulping and deinking system based on waste paper and the operation process thereof, bubbles generated by deinking are scraped and collected through an arc-shaped defoaming scraper, a helical gear ring is meshed with a helical gear, and a centrifugal barrel on the surface of an auxiliary roller rotates and pushes a limiting defoaming needle to move up and down, so that the limiting defoaming needle punctures the bubbles scraped and collected by the arc-shaped defoaming scraper; and the situation that a large number of bubbles are generated through stirring of equipment and then leveling of the deinking liquid is affected is avoided, and the deinking treatment efficiency of the equipment is effectively improved.

Description

technical field [0001] The invention relates to the technical field of deinking, in particular to an efficient, clean and damage-free pulping deinking system based on waste paper and its operating process. Background technique [0002] With the improvement of people's quality of life, the rise of online shopping and the rapid development of the logistics industry, people's demand for packaging paper is increasing, and papermaking from waste paper is the most environmentally friendly papermaking method. In order to make printed waste paper into To meet the production requirements of white paper pulp, to improve the use value of waste paper pulp and the grade of paper produced, it is necessary to remove ink, resin, etc. from waste paper. The process of this treatment is deinking of waste paper. [0003] The existing equipment will generate more air bubbles during the paper-ink separation process of waste paper. If a large amount of defoamer and other additives are added, it wi...

Problems solved by technology

[0004] Aiming at the deficiencies of the prior art, the present invention provides an efficient, clean, non-damaging pulping and deinking system based on waste paper and its operating process, which solves the problem of more waste paper and ink separation in the existing waste paper Air bubbles, if a large dose of defoamer and other additives are added, will have a negative impact on the separation of waste paper and ink, and waste paper fibers are easily cut and chopped by the flying knife of the pulper and lost in large quantities, resulting in waste of fibers and The problem of rising costs
