Clean production equipment and process for whole pulping and papermaking process

Abstract

The invention discloses clean production equipment and a clean production process for a whole pulping and papermaking process, relates to the field of pulping equipment, and aims to solve the problems that equipment required by physical cracking and mechanical cracking are independently arranged during pulping in a conventional way of matching biological pulping with physical cracking, so that paper pulp needs to be continuously transported, and the pulping efficiency is high. In order to solve the problem that paper pulp is not clean enough due to the fact that the paper pulp is continuously polluted during transportation, the invention provides the following scheme that a pressing block is arranged in a reaction kettle, a batching cup is arranged at the top of the pressing block, a stirring mechanism is arranged in the batching cup, and a rotating mechanism is arranged on the outer side of the batching cup; a filter plate is arranged at the bottom of the reaction kettle, a separation mechanism is arranged at the bottom of the filter plate, and silk separation equipment is arranged at the bottom of the separation mechanism. According to the clean production equipment and process for the whole pulping and papermaking process, the stirring mechanism arranged in the equipment is of a telescopic structure and is matched with the rotating mechanism to conveniently stir paper pulp.

Description

technical field [0001] The invention relates to the field of pulping equipment, in particular to a clean production equipment and process for the whole process of pulping and papermaking. Background technique [0002] The existing pulping and papermaking method usually adopts the chemical pulping method. This method removes too much waste liquid during the pulping process and increases the degree of pollution. Therefore, the method of biological pulping and physical cracking appears to be used for pulping. Discharge, no pollution, no odor, no suspended solids, water saving, electricity saving, coal saving, raw material saving, and production cost reduction, however, the existing biological pulping method combined with physical cracking is used for pulping, due to physical cracking. The equipment required for mechanical cracking is set independently, so it is necessary to continuously transport the pulp. This process is too troublesome to operate, and there are certain safety...

Problems solved by technology

[0004] The invention proposes a clean production equipment and process for the whole process of pulping and papermaking, which solves the problem that the equipment required for physical cracking and mechanical cracking are independently set during pulping in the existing method of biological pulping combined with physical cracking. , so the pulp needs to be transported continuously. This process is too cumbersome and has certain safety hazards. At the same time, the pulp will be continuously polluted during transportation, which will lead to the problem that the pulp is not clean enough.
