Dispersive type pulp preparation method

Abstract

The invention relates to the technical field of pulping, in particular to a dispersive pulping method which comprises a stirring assembly, a discharging assembly and a guiding assembly. By arranging the material guiding assembly in the stirring barrel, when a servo motor in the stirring assembly drives a stirring rod on a first rotating shaft to rotate and stir in the stirring barrel; a material guiding sleeve in the material guiding assembly can prevent paper pulp from rotating along with rotation of the stirring rod, so that vortex can be effectively prevented from being generated by mixed liquid of plant fibers and water; then the first rotating shaft can drive the first gear to rotate through the second gear during rotation, and the first gear can drive the second rotating shaft to rotate during rotation, and the second rotating shaft can drive the spiral fan blades located in the material guide sleeve to conduct spiral feeding when rotating, so that the plant fibers settled at thebottom in the stirring barrel can be conveyed to the inner top of the stirring barrel, and therefore the plant fibers can be better mixed with water to form paper pulp.

Description

technical field [0001] The invention relates to the technical field of pulping, in particular to a dispersed pulping method. Background technique [0002] Paper is a thin sheet made of pulp, which is a fibrous substance made from plant fibers through different processing methods. It can be divided into mechanical pulp, chemical pulp and chemical mechanical pulp according to the processing method, and 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. When paper is manufactured, it is necessary to use a pulper to stir and break the plant fibers to make pulp. [0003] Most of the existing pulping machines directly drive the stirring rod to rotate in a single direction inside the mixing tank through the servo motor. Since the pulp i...

Problems solved by technology

[0003] Most of the existing pulping machines directly drive the stirring rod to rotate in a single direction inside the mixing tank through the servo motor. Since the pulp is a mixed liquid made by mixing water and plant fibers, the stirring rod is in the inside of the mixing tank. When rotating in a single direction, the mixed liquid will be driven to rotate with the direction of the stirring rod to generate a vortex phenomenon, forming a spiral water vortex, which will cause the pulp to be unable to be stirred effectively, and the feeding method of the existing pulper Most of the feeding is carried out through the feeding pipe with a small diameter. Because the pulp is relatively viscous, the plant fiber and water will be separated when the pulp is fed, so that the pulp cannot be fed effectively, and a large amount of pulp will adhere to the on the inner wall of the mixing tank
