Abstract

The invention relates to the technical field of production of dioctyl terephthalate from waste polyester filaments, in particular to a waste polyester filament crushing device and a using method thereof.The waste polyester filament crushing device comprises a stock bin, a crushing bin and a discharging port which are sequentially communicated from top to bottom; a feeding mechanism, a first crushing mechanism and a second crushing mechanism are sequentially arranged in the crushing bin from top to bottom, and the feeding mechanism is arranged under the stock bin and comprises two feeding rods which are symmetrically arranged and a driving assembly for driving the feeding rods to relatively rotate in the polyester waste yarn conveying direction; and the second crushing mechanism comprises a filter screen, and the discharge port is formed below the filter screen. Automatic feeding can be achieved, and the labor intensity of workers is reduced; in the automatic feeding process, waste polyester filaments are preliminarily cut, the waste polyester filaments are prevented from winding a roller, and the production continuity and safety are improved; the waste polyester filaments subjected to multi-stage crushing are small in granularity and uniform in size, and the process requirement for producing dioctyl phthalate through alcoholysis of the waste polyester filaments is fully met.

Description

technical field [0001] The invention relates to the technical field of producing dioctyl terephthalate by utilizing polyester waste silk, in particular to a polyester waste silk crushing device and a method for using the same. Background technique [0002] In recent years, polyester has been widely used in chemical fiber, plastic bottles, textiles and other fields, and a large amount of polyester waste is produced every year. . With the development of science and technology and the needs of environmental protection, the recycling and reuse of polyester has been continuously studied. Among them, the use of polyester waste to produce dioctyl terephthalate has been industrialized. In the process of using polyester waste to produce dioctyl terephthalate, the polyester waste needs to be alcoholyzed. In order to speed up the alcoholysis, the enterprise takes measures to first crush the polyester waste and then alcoholysis. [0003] Polyester waste blocks can be crushed by conven...
