Embodiment Construction

[0026] The present invention will be further described in conjunction with the accompanying drawings and specific embodiments.

[0027] Embodiments of the invention are:

[0028] refer to figure 1 , a new copy paper pulping method, including a disintegrator 101, a disintegration tank 102, a discharge tank 103, two knocking pools 104, a beater 105, a knocking tank 106, a mixing tank 107, a recovery tank 108, Slag remover 109, head box 110, headbox 111, press machine 112, dryer machine 113, coiler 114, paper cutter 115, the pulping method is as follows:

[0029] 1) The waste paper is disintegrated by the disintegrator 101 to form a dry slurry and flows into the disintegration tank 102;

[0030] 2) Take 5 parts of dry slurry from the disintegration tank 102 and put it into the discharge tank 103, and simultaneously get 95 parts of water and add it to the discharge tank 103 for dilution, and prepare a slurry with a concentration of 5%;

[0031] 3) The slurry with a stable conce...

Abstract

The invention relates to the technical field of papermaking, particularly to a novel coper paper pulping method. The novel coper paper pulping method mainly solves the problems in the prior art that instable concentration of disintegrated pulp results in high wearing of a grinding disc of a grinding machine and quality fluctuation ad rejection rate increased of produced paper products impact the overall production efficiency of a paper machine. The novel coper paper pulping method comprises a disintegrating machine, a disintegrating pool, a discharging pool, at least two chest before refiners,a pulping machine, a beating pool, a regulating pool, a recycling pool, a deslagging unit, a high tank, a pulp tank, a press, a dryer, a winding machine and a paper cutting machine.

Description

technical field [0001] The invention relates to the technical field of papermaking, in particular to a novel copy paper pulping method. Background technique [0002] At present, the papermaking process includes: pulp sheet preparation—pulp sheet crushing—beating or refining—pulp blending—purification—pulp screening—flow box discharge—mesh dehydration—press dehydration—drying—calendering—rolling - Rewinding - Packaging. The above-mentioned papermaking process is partially adjusted according to the different types and specifications of the paper to be produced. In the process of using waste paper to produce copy paper according to the above-mentioned process, there are problems such as high water consumption and short service life of abrasive discs, which have plagued the normal production of copy paper for a long time. [0003] Chinese Patent No.: 201510004198.5 discloses a production system for low-quantity color copy base paper, including a slurry pretreatment subsystem, ...
