Problems solved by technology

[0004] The particle size of the cotton particles is high in the process of the reaction of cellulose ether. Cotton particles with large particle sizes will lead to insufficient reaction, waste of raw materials and impurities mixed in the finished product, which are difficult to separate. Cotton raw materials are often not too

Abstract

The invention discloses a crushing system for cellulose ether production raw materials. The crushing system comprises a cotton crusher, a cotton feeder and a coarse material return feeder. A cotton loosening working cavity, a crushing working cavity and a feeding funnel are arranged on the cotton crusher, the feeding funnel is arranged above the left side of the cotton loosening working cavity, acotton loosening device is installed on the cotton loosening working cavity, a cotton crushing device is installed on the crushing working cavity, a coarse material return inlet is arranged on the side surface of the crushing working cavity, the lower end of the crushing working cavity is connected with a screening discharging box through a flange, a discharge outlet of the cotton feeder is arranged over the feeding funnel, and a discharge outlet of the coarse material return feeder is arranged over the coarse material return inlet. The structure is novel, the cotton loosening device is arranged, cotton materials are scattered and loosened firstly, caking is prevented, the subsequent crushing efficiency is accelerated, the crushing effect is improved, a screening device is arranged at an outlet, large-particle-size cotton particles are separated and enter the crushing device again for crushing, and the crushing system has the advantages of high crushing efficiency, high raw material utilization rate and stable discharge particle size.

Description

Technical field [0001] The invention relates to the technical field of chemical raw material production equipment, in particular to a crushing system for cellulose ether production raw materials. Background technique [0002] Cellulose ether is a polymer compound with ether structure made of cellulose. Cellulose is a polyhydroxy polymer compound that neither dissolves nor melts. After etherification, cellulose can be dissolved in water and dilute alkali. Solutions and organic solvents, and have thermoplasticity, cellulose ethers have a wide range of varieties and excellent performance, and are widely used in construction, cement, petroleum, food, textile, detergent, paint, medicine, paper and electronic components industries. [0003] Cellulose ethers include methyl cellulose, hydroxyethyl methyl cellulose, carboxymethyl cellulose, ethyl cellulose, benzyl cellulose, hydroxyethyl cellulose, and hydroxypropyl depending on the etherification agent used. Methyl cellulose, etc., cotton...
