Abstract

The invention discloses a waste paper treatment device for kraft linerboard production, and particularly relates to the technical field of waste paper treatment.The waste paper treatment device comprises a base, a straight barrel is arranged at the top of the base, a partition plate is fixedly arranged in the middle of the inner circumferential face of the straight barrel, and a paper pulp treatment mechanism is arranged between the straight barrel and the base; and a plurality of stand columns which are evenly distributed and fixedly connected with the base are arranged between the paper pulp processing mechanism and the base, a waste paper processing mechanism is arranged at the position, located above the partition plate, in the straight barrel, and a feeding pipe is arranged on one side of the top end of the peripheral face of the straight barrel in a communicating mode. After paper pulp is formed, an air cylinder drives a pressing block to ascend and descend in a reciprocating mode, so that the paper pulp is subjected to quantitative filter pressing, incomplete filter pressing caused by too much paper pulp subjected to one-time filter pressing is avoided, and after paper pulp filter pressing is completed, the air cylinder is used for jacking the pressing block to the initial position and continues to push the pressing block to move upwards; and the filter cake left after filter pressing in a net barrel is completed is lifted, and the filter cake is convenient to take out.

Description

technical field [0001] The invention relates to the technical field of waste paper treatment, and more specifically, the invention relates to a waste paper treatment device for kraft cardboard production. Background technique [0002] Kraft cardboard is tougher and more solid than ordinary cardboard, has extremely high compressive strength, puncture resistance and folding resistance, and has the characteristics of good moisture resistance and good appearance quality. It is mainly used for the manufacture of foreign trade packaging cartons and domestic High-end commodity packaging cartons. Waste paper treatment is the process of reprocessing recycled waste paper to obtain qualified fibers for the production of paper products. The recycling and utilization of waste paper is conducive to protecting the environment, protecting forests and saving resources. Waste paper can be reused many times. The usual process is to crush waste paper raw materials, cook, wash, screen, bleach,...
