Description

Technical Field

[0001] The utility model relates to the technical field of pre-oxidized fiber processing, in particular to pre-oxidized fiber pretreatment equipment. Background Art

[0002] Preoxidized fiber is a high-strength, high-modulus fiber, usually made of polyacrylonitrile (PAN) polymer. Before preparing preoxidized yarn, PAN fiber needs to undergo a pretreatment step, called preoxidation. Preoxidized fiber has a high carbonization performance, that is, at high temperature, it can be further heat treated to obtain high-purity carbon fiber. Since the preoxidized fiber contains more impurities that need to be cleaned, it needs to be pretreated. The existing publication number CN219991915U discloses a preoxidized fiber pretreatment device, which drives the drum to rotate at the top of the cleaning tank through a motor, and the cleaning tank drives the fixed plate to stir inside the cleaning tank to clean the fibers inside the cleaning tank. Then, the fixed plate is driven by the drum to rotate, and a thrust is applied to the fibers inside the cleaning tank, so that the fibers move inside the cleaning tank, and the fibers can be automatically cleaned and washed to remove impurities inside the fibers, which is convenient for later processing and practical use. However, the pretreatment device only cleans the fibers by pushing them, and the cleaning effect is poor. It is difficult to quickly remove impurities in the preoxidized fibers, which reduces the efficiency of the preoxidized fiber pretreatment and brings certain adverse effects. Therefore, it needs to be improved. Utility Model Content
