Coaxial liquid nitrogen inner injection and high-frequency microseismic coupling waste fabric crushing device and method

Abstract

The application discloses a coaxial liquid nitrogen internal injection and high-frequency microseismic coupling waste fabric crushing device and method, and aims to solve the problems of easy winding caused by molten adhesion of traditional waste fabric processing caused by friction heat, uneven crushing granularity and high energy consumption in the prior art. Through the coaxial liquid nitrogen internal injection and high-frequency microseismic coupling technology, efficient utilization of cold energy, in-situ embrittlement of materials, micron-level crushing of fibers, and the crushing device and method integrating feeding, compression, deep cold embrittlement and microseismic crushing are realized. The crushing device and method are suitable for recycling of high-toughness fiber materials such as waste clothes, production scraps, chemical fiber cotton hemp blended fabrics and the like.
