Dehydrating and drying device for sodium carboxymethyl cellulose production

Abstract

The invention discloses a dehydrating and drying device for sodium carboxymethyl cellulose production. The dehydrating and drying device for sodium carboxymethyl cellulose production comprises a cylindrical casing, wherein a vertically-arranged rotary drum is arranged at the middle part of an inner cavity of the casing, and a plurality of filter holes are formed in the side wall of the rotary drum; and a through hole is formed in the center of the top of the rotary drum, a rotary shaft driven by a motor is inserted into the through hole in a penetrating mode, an installation table is arranged at the bottom end of the rotary shaft, squeezing mechanisms matched with the inner wall of the rotary drum are arranged at the two sides of the installation table, and a transmission mechanism connected with the rotary shaft and used for driving the rotary shaft to rotate is arranged at the top of the rotary drum. According to the invention, by arranging the motor, the rotary drum, the squeezing mechanisms, the transmission mechanism and other structures, the motor drives the rotary drum to rotate at a high speed to generate centrifugal force, materials are tightly attached to the inner wall of the rotary drum under the action of the centrifugal force, water in the materials is thrown out of the filter holes, meanwhile the squeezing mechanisms carry out rolling and squeezing treatment on the materials which are tightly attached to the inner wall of the rotary drum, and the water is further squeezed out from the materials, so that an excellent dehydrating is achieved.

Description

technical field [0001] The invention relates to a dehydration and drying device for producing sodium carboxymethyl cellulose, belonging to the technical field of cellulose production. Background technique [0002] Carboxymethyl cellulose CMC is a kind of important cellulose ether, is a kind of polyanionic compound with good water solubility obtained after chemical modification of natural fibers, and is easily soluble in cold and hot water. It has unusual and extremely valuable comprehensive physical and chemical properties such as emulsifying dispersant, solid dispersibility, non-perishable, and physiologically harmless, and is a natural polymer derivative with a wide range of uses. Due to its thickening, water retention, metabolic inertness, film forming, dispersion stability and other properties, it can be used as a thickener, water retention agent, binder, lubricant, emulsifier, suspending agent, tablet matrix , biological matrices and biological product carriers, etc. ...

AI Technical Summary

Problems solved by technology

Now most of the factory production of CMC is to use refined cotton as raw material, in the production process of CMC, the refined cotton needs to be dehydrated and dried, and the dehydration and drying efficiency of the existing equipment is not high
