Description

Technical Field

[0001] The utility model relates to the technical field of viscose fiber production, in particular to a filter for viscose fiber production. Background Technique

[0002] Viscose fiber is the full name of viscose. It uses "wood" as raw material and is a cellulose fiber obtained by extracting and reshaping fiber molecules from natural wood cellulose. Its preparation process is as follows: plant cellulose is alkalized to form alkali cellulose, and then reacts with carbon disulfide to form cellulose xanthate. The viscous solution obtained by dissolving it in dilute alkali solution is called viscose. After wet spinning and a series of treatment processes, viscose becomes viscose fiber.

[0003] The "viscose filtering and recycling device" disclosed in its application number "202222415839.4" "comprises a pool body, a partition is arranged in the pool body, and the inner cavity of the pool body is divided into a filtering cavity and a recycling cavity by the partition. An overflow port is opened at the partition near the pool mouth. A liquid delivery pipe is arranged at the bottom of the filtering cavity. A number of bundles of fiber filaments are arranged in the filtering cavity. The bundled fiber filaments are arranged in rows to form a filtering layer, and the filtering layer is close to the bottom of the filtering cavity". In the utility model, after the plasticizing water enters the filtering cavity and the water level rises to the filtering layer formed by the fiber filaments, the plastic particles are intercepted by the fiber filaments in the filtering layer. After being filtered, the plasticizing water enters the recycling cavity through the overflow port for recycling. The device has a simple structure, a large filtering capacity, a strong sewage interception ability, and the fiber filaments are inexpensive, reducing the use cost of the equipment.
