Description

[0002] Sodium carboxymethyl cellulose is a widely used natural polymer chemical, which is usually formed by introducing carboxymethyl groups into cellulose through chemical reaction and combining with sodium ions to form a sodium salt. It is a derivative of cellulose, has good water solubility and multifunctional properties, and thus has a wide range of applications in various industries. The sodium carboxymethyl cellulose circulating crushing and dust removal device is mainly used for efficient crushing and dust removal treatment during the production or processing of sodium carboxymethyl cellulose, so as to reduce environmental pollution and improve production efficiency.

[0003] The prior art uses a bag dust collector to effectively capture and recover the dust generated during the crushing of sodium carboxymethyl cellulose. However, the filtered dust adheres to the inner wall of the bag, and the filtered dust accumulates at the bottom of the bag.
