Refined cotton alkali soaking system

Abstract

The invention discloses a refined cotton alkali treating system. A cotton feeding tube is arranged on one side of the alkali pre-treating cavity, an alkali liquor feeding tube is arranged on the other side of the alkali pre-treating cavity, a liquor draining end of the alkali liquor feeding tube is respectively placed at the bottom of the alkali pre-treating cavity and the bottom, the top of the alkali pre-treating cavity is connected with one end of an exhaust duct through a flange structure, the other end of the exhaust duct communicates with the inside of a cyclone, a cyclone liner is arranged at an upper air outlet of the inside of the cyclone, the bottom of the cyclone communicates with an impurity collecting bin, and a flap valve is mounted at the bottom of the alkali pre-treating cavity; and a feeding opening is formed in the right side of the top of an extrusion barrel, a support frame is arranged on the left side of the top of the extrusion barrel, and an alkali liquor discharging opening is formed in the bottom of the extrusion barrel. The refined cotton alkali treating system has the advantages that the structural design is reasonable, the quality of refined cotton products can be guaranteed, the alkali liquor can fully permeate in cotton linter fiber cavities, the extrusion effect is good, and the extrusion efficiency is greatly improved.

Description

technical field [0001] The invention relates to the technical field of refined cotton, in particular to the technical field of refined cotton soaked in alkali. Background technique [0002] Refined cotton is a cellulose material made from cotton linters and refined by alkaline cooking. Cotton linters contain oils, lignans, fats, waxes and other substances. Caustic soda is used as a cooking aid to react with saponification and emulsification with the substances contained in cotton linters to achieve the purpose of removing non-cellulose. Therefore, caustic soda It is very important that the cooking aid penetrates fully and evenly into the linter fibers. Usually, in the production process, there are presoaking and spiral impregnation links, but the existing presoaking technology still has certain defects: first, it is difficult for cotton linters to fully absorb caustic soda cooking aids, and cotton linter fibers are not soaked in soda. Completely, there will be free fibers ...

AI Technical Summary

Problems solved by technology

Usually, in the production process, there are presoaking and spiral impregnation links, but the existing presoaking technology still has certain defects: first, it is difficult for cotton linters to fully absorb caustic soda cooking aids, and cotton linter fibers are not soaked in soda. Completely, there will be free fibers affecting the product quality; second, the existing pre-soaking process does not take reasonable consideration of impurity removal, and some impurities are still soaked with cotton linters, which affects the fiber response

After the cotton linters are pre-soaked with alkali, it is necessary to carry out spiral alkali soaking, so that the lye absorbed by the surface of the cotton linters can fully penetrate into the fiber cavity of the cotton linters. When the existing alkali soaking device is in use, the lye Insufficient penetration will adversely affect subsequent production and reduce the quality of refined cotton products
