Problems solved by technology

[0005] In order to overcome the prior art, when producing cellulose acetate, in order to increase the contact area between the raw material cotton pulp and the reagent, it is necessary to firstly mix the cotton pulp Make it fluffy, and add it to the cellulose acetate processing equipment at a uniform speed. The existing equipment has a low degree of refinement of cotton pulp and is not easy to clean; for the convenience of transportation and storage, the cotton pulp will be compressed into blocks. At this time, the cotton pulp The interior of the meal is compact, and it takes a lot of time to loosen it. The technical problem of the present invention is to provide a multi-stage refining device for cellulose raw materials with controllable feeding

Abstract

The invention relates to the field of cellulose processing, in particular to a multi-stage cellulose raw material refining device capable of controlling feeding. To overcome a technical problem in the prior art, the invention provides the multi-stage cellulose raw material refining device capable of controlling feeding. According to a technical scheme in the invention, the device comprises a supporting frame body, a control screen, a first-stage loosening system, a second-stage loosening system and an adjustable feeding system, wherein the second-stage loosening system is connected with the first-stage loosening system, and the adjustable feeding system is connected with the primary loosening system. According to the device, cotton pulp can be controllably and stably transferred into cellulose acetate processing equipment; the cotton pulp which is compressed into a cluster and is compact inside during transportation and storage in the prior art is subjected to multi-stage refining, so the cotton pulp becomes fluffy and is separated from one another, which is beneficial for subsequent full contact between the cotton pulp and a reagent; and meanwhile, all the parts of the device are easy to disassemble and clean, and all the systems can work independently.

Description

technical field [0001] The invention relates to the field of cellulose processing, in particular to a multi-stage refining device for cellulose raw materials with controllable feeding. Background technique [0002] Cellulose acetate and its derivatives are made of natural wood pulp or cotton pulp, with acetic acid as solvent and acetic anhydride as acetylating agent. Washing, pressing, drying and other processes to obtain cellulose acetate and its derivatives are one of the earliest cellulose organic esters for industrial application. [0003] In the prior art, when producing cellulose acetate, in order to increase the contact area between the raw material cotton pulp and the reagent, it is necessary to first make the cotton pulp fluffy and add it to the cellulose acetate processing equipment at a uniform speed. The device has a low degree of refinement of cotton pulp and is not easy to clean; cotton pulp will be compressed into blocks for convenient transportation and stor...
