Embodiment Construction

[0014] The present invention will be further described in conjunction with the following examples.

[0015] The preparation process of the all-waste paper liner linerboard comprises the following steps:

[0016] A: The waste paper is sent to the pulper through the chain plate conveyor to be broken into pulp, and at the same time, the garbage is pulled out by the garbage rope, and the garbage and the slurry containing heavy impurities are pulled away by a car; the slurry containing heavy impurities Heavy impurities and sludge are discharged through sand chambers, hydraulic slag cleaners, cylinder screens and extruders;

[0017] B: Send the pulp to a high-concentration desander to further remove heavy impurities, adopt the intermittent slag discharge method, discharge the slag through the sand discharge machine, and then send the pulp to the coarse stock tower;

[0018] C: The pulp in the rough pulp tower is screened by the three-stage coarse screening system to discharge the s...

Abstract

The invention discloses a manufacture process of all waste paper dried noodle cardboard paper, comprising the following steps: A: conveying the waste paper to a pulper through a scraper chain conveyor, and crushing the waste paper into paper pulp; B: conveying the paper pulp to a high concentration desander, and further removing the heavy impurities; C: screening out the pulp dregs and the impurities containing the heavy impurities from the paper pulp in a rough pulp tower by utilizing a three-section rough screen system; D: carrying out slag removal on the long fiber pulp by utilizing a long fiber three-section low concentration desander system, then feeding the fine pulp after the long fiber three-section low concentration desander into a three-section fine screen system to screen finely, and finally performing the paper making by utilizing a long fiber grinding back pool, a bottom machine chest and a paper remover; and E: carrying out slag removal on the short fiber pulp by utilizing a short fiber three-section low concentration desander system, and finally performing the paper making by utilizing a core machine chest and a paper remover. By utilizing the process provided by the invention, the product having the quality same as that of the dried noodle cardboard paper which is manufactured by the raw material of wood pulp can be produced, thereby greatly reducing the cost and ensuring the effective use of renewable resources.

Description

technical field [0001] The invention relates to the technical field of papermaking, in particular to a preparation process of all waste paper linerboard. Background technique [0002] The raw materials for the preparation of containerboard paper generally use two raw materials: virgin wood pulp and waste paper wood pulp. Virgin wood pulp has better burst resistance and performance, but the cost is higher, and waste paper wood pulp is lower in cost but requires more Pretreatment process, poor strength. From the perspective of environmental protection, the trend in the industry is to reduce the use of virgin wood pulp as much as possible, save living resources, and recycle renewable resources as much as possible. At present, there is no preparation process that fully adopts waste paper pulp as the raw material of linerboard. Contents of the invention [0003] The purpose of the present invention is to avoid the deficiencies in the prior art and provide a kind of preparatio...
