A kind of papermaking pulp preparation raw material pretreatment processing equipment and processing technology

Abstract

The present invention relates to a papermaking pulp preparation raw material pretreatment processing equipment and processing technology, comprising a base, a feed unit and a humidity control unit, the feed unit is arranged on the left side of the upper end of the base, and the humidity control unit is arranged on the right side of the upper end of the base ; The present invention solves the problem that the water mist is difficult to penetrate into the wheat straw in the water mist spray mode by turning over the wheat straw, and the turning mechanism is driven by the feeding of the conveyor belt, and the transmission concept of one machine with multiple functions is realized. It solves the problem that water mist is difficult to penetrate into the wheat straw without adding a new driving source; by recycling excess water, filtering it and then using it, the production cost of the factory is reduced.

Description

technical field [0001] The invention relates to the technical field of papermaking, in particular to a pretreatment processing equipment and processing technology for raw materials for paper pulp preparation. Background technique [0002] Pulp is a fibrous substance made from plant fibers through different processing methods. According to the processing method, it can be divided into mechanical pulp, chemical pulp and chemical mechanical pulp; it can also be divided into wood pulp, straw pulp, hemp pulp, reed pulp, sugarcane pulp, bamboo pulp, rag pulp, etc. according to the fiber raw materials used. According to different purity, it can be divided into refined pulp, bleached pulp, unbleached pulp, high-yield pulp, semi-chemical pulp, etc. Generally used in the manufacture of paper and cardboard. In addition to being used for the manufacture of specialty papers, refined pulp is often used as a raw material for the manufacture of cellulose derivatives such as cellulose este...

AI Technical Summary

Problems solved by technology

[0003] In the process of pulp production, the raw materials need to be pretreated. In the process of pretreatment of raw materials, there are the following problems: 1. In the process of using water mist to adjust the humidity of wheat straw, although the way of water mist to adjust humidity can save water and prevent wheat straw The consumption of raw materials, but it will cause the problem that the moisture inside the wheat straw is difficult to penetrate, so that the wheat straw is not completely soaked, thus affecting the treatment of the subsequent process; 2. When the moisture is adjusted to the wheat straw, when the moisture is too much, it will overflow and consume water resources. , which increases the production cost of the factory
