Abstract
Description
Technical Field
[0001] This utility model relates to the field of plastic recycling technology, specifically a waste textile plastic recycling device. Background Technology
[0002] In the production of plastic products, the chemical properties of synthetic fibers (such as polyester and nylon) in waste textiles can be utilized to decompose or reshape them into plastic raw materials through physical or chemical treatment. Polyester fiber (PET, accounting for more than 60% of global textiles) is a primary target because its molecular structure can be repolymerized into plastic granules through hydrolysis or alcoholysis. Waste textile pretreatment involves crushing, washing, drying, and sorting, after which the waste textiles are mixed with plastics and heated to melt.
[0003] In existing equipment, fibers and plastic granules are mixed and fed into the hopper during the heating and melting process. Due to the interaction between particles and airflow disturbances, dust is easily generated, and this dust is directly emitted, affecting processing. To address these issues, a waste textile plasticizing device is proposed. Utility Model Content
