Abstract

The invention discloses an oil and water removal device and a particle regeneration manufacturing method based on waste polyester filaments. The method comprises the following steps: cutting off, granulating, oil removal, extrusion, alcoholysis, primary filtration, secondary filtration and pelletizing, carrying out oil and water removal on pellets through the oil and water removal device, introducing a melt into an underwater pelletizer, and pelletizing into polyester chip particles. According to the oil and water removal device and the particle regeneration manufacturing method based on the waste polyester filaments, the oil removal, alcoholysis and homogenization tackifying procedures are specially designed, the production process is optimized, various different types of waste polyester filaments are recycled in a high-valued mode, various indexes of produced regenerated polyester chip particles are excellent, the production of filaments for home textiles can be met, and the waste polyester filaments are recycled.

Description

technical field [0001] The invention relates to the technical field of recycling polyester waste silk, in particular to an oil and water removal device and a particle regeneration manufacturing method based on polyester waste silk. Background technique [0002] A large amount of waste silk will be generated in the long and short line production and weaving process. In order to reduce the cost, it needs to be recycled. The existing method of recycling polyester waste silk is mainly through crushing and granulating into silk bubbles, which are recycled and reused by physical methods. The invention patent application with the application number 201710557878.9 discloses a method for producing regenerated slices with bright nylon 6 waste silk. The specific steps include: 1) silk selection, 2) feeding, 3) screw host extrusion, heating, discharging Gas, filtration, 4) Heating, filtration, and injection of strips under the screw, 5) Water cooling and drying of strips, 6) Cutting of...
