One-stop pulping machine

Abstract

The invention discloses a one-stop horizontal-type pulping machine. The pulping machine includes a machine body, a turning plate, a material inlet, a material outlet and a motor; the machine body includes an inner shell and an outer shell; the turning plate is arranged on the inner wall of the inner shell, and the setting angle of the turning plate is inclined to a conveying direction of a material in the inner shell; the motor is arranged at the end part of the machine body and is used to drive the inner shell to rotate along the horizontal central axis; and the material inlet is arranged inone end of the machine body, the material outlet is arranged in the other end of the machine body, and the material inlet and the material outlet are in communication with the inner shell. According to the one-stop pulping machine provided by the invention, softening and pulping processes can be completed in one stop in the same equipment, and continuous production of continuous feeding and continuous discharging can be realized instead of a single-pot batch production.

Description

technical field [0001] The invention belongs to the technical field of papermaking, and in particular relates to a one-stop pulping machine. Background technique [0002] Paper is an important item closely related to human life. It has developed into a raw material for packaging, printing, cigarettes, stationery, machinery, building materials, military industry and other industries. The paper industry has a wide range of applications in all walks of life. The development of the paper industry directly It reflects the level of a country's national economy and civilization construction. my country is a big country for papermaking and papermaking, and papermaking has become an important basic industry that drives the development of the national economy. [0003] As we all know, the preparation of paper needs to consume a large amount of pulping raw materials, and China is a country with few forests and many fields, with a forest coverage rate of only 16.35%. Not only that, our...

Problems solved by technology

[0004] The traditional papermaking process is to process the papermaking raw materials through pulping, modulation, papermaking, processing and other main processing steps. Among them, pulping is the first step and the most critical step in papermaking. The pulping process is to remove the pulping raw materials. The process of lignin; the removal process is mainly divided into chemical pulping method, mechanical pulping method and semi-chemical pulping method. Chemical pulping method is the most widely used production method. The tablet is continuously cooked in the device, so that the lignin in the pulping raw material reacts with chemical reagents at high temperature to produce water-soluble matter, which is separated from the fiber to form a slurry; although chemical pulping retains the natural length of the fiber, most of it is removed. lignin, but the pulping efficiency is low and the pulp yield is low
