Embodiment

[0056] The sizing material of a certain paper mill is processed in the following steps:

[0057] The first step is to separate the rubber material stored in the rubber material storage barrel through a rubber material first-stage sieve to obtain good rubber and slag rubber, and the good rubber is directly used in the gluing machine;

[0058] In the second step, the slag glue obtained through the first-stage sieving of the above rubber material and the back glue produced by the gluing machine enter the filter box 32 of the filter slag removal mechanism together, and the first motor and the second motor are turned on at the same time, and the slag is removed through filtration. The separation function of the mechanism can obtain pre-good glue and heavy slag, and the heavy slag is left on the first filter plate 3201 and the second filter plate 3202, and the heavy slag is collected in the sediment collection tank;

[0059] The third step, the pre-good glue obtained by the filter a...

Abstract

The invention discloses a pulping and papermaking glue recovery processing technology. The pulping and papermaking glue recovery processing technology comprises the following steps that the first step, glue which is stored in a glue storage barrel is separated by a glue first-section screen, and good glue is directly used by a gluing machine; the second step, residue glue which is obtained throughthe separation conducted by the glue first-section screen and returning glue which is generated by the gluing machine enter a filtering and residue removing mechanism together to be separated, and heavy residues are collected in a sediment collecting pool; and the third step, beforehand good glue which is obtained through the filtering and residue removing mechanism is processed by a vibrating screen, light residues are collected in a paper fur collecting tank, and good glue is collected in the glue storage barrel. According to the pulping and papermaking glue recovery processing technology,in the glue recovery process, the filtering and residue removing mechanism is additionally arranged in front of the vibrating screen to conduct the separation of the heavy residues, the heavy residuescan be removed, then the light residues which mainly include paper fur are removed by the vibrating screen, and therefore the light residues can be recycled, the cleanliness of the glue is also substantially improved, the service lives of a scraping rod, a gluing roller and the vibrating screen are prolonged, and the cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of papermaking, and in particular relates to a pulping and papermaking glue recycling process. Background technique [0002] The current PM6 paper machine production line mainly produces T paper for liner board. The raw materials are mainly waste paper. The quality of the raw waste paper is poor, and the paper wool is more. The glue of the system is easily dirty, so the glue needs to be handled. There is only one square vibrating sieve for the reflux treatment of the rubber material, and the treatment effect is still not ideal, and the light impurities and heavy impurities in the rubber material cannot be separated, resulting in more and more dirty rubber material circulation. Short, resulting in increased costs. [0003] The Chinese patent application with the patent number CN201821570581.2 discloses a glue recovery and purification device for white cardboard. The material is fed through the feeding pipe,...
