Device for separating components of waste polyester-cotton blended fabric

Abstract

The invention relates to a device for separating components of waste polyester-cotton blended fabric. The device is a horizontal rotary alcoholysis separation device and consists of an outer barrel and an inner barrel; the outer barrel is connected with a vacuum reflux condensing device; heating elements and a heat insulation layer are arranged at the periphery of the barrel wall of the outer barrel; the inner barrel is horizontally arranged in the outer barrel along the axial direction; through holes or meshes are formed in the barrel wall of the inner barrel; the inner barrel is provided with a vacuum / micro-pressure dual-purpose mechanical seal rotating shaft, and the rotating shaft passes through the outer barrel and is connected with a motor; the rotating shaft is driven by the motor, so that the rotating action of the inner barrel can be realized in a micro-pressure or vacuum state; the tail end of the vacuum reflux condensing device is connected with a collecting tank; the collecting tank is connected with a vacuum apparatus. When the device is used for carrying out alcoholysis on the waste polyester-cotton blended fabric, the process of stirring is omitted, so that the problem of property damage caused by winding of rest cotton yarns during stirring can be solved; the problems that an alcoholysis agent is left over in the rest cotton yarns, discharge is difficult to realize, and the like are solved; therefore, after the device is adopted, the components of the waste polyester-cotton blended fabric are efficiently and conveniently separated and recovered.

Description

technical field [0001] The invention relates to a component separation device for polyester-cotton blended fabrics, in particular to a component separation device for polyester-cotton blended fabrics in a horizontal centrifugal alcoholysis kettle. Background technique [0002] my country is a large textile country, with a stock of waste textiles of 26 million tons per year, including 18 million tons of chemical fibers (12 million tons of polyester), and 8 million tons of natural fibers. Polyester is divided into pure polyester, polyester cotton, polyester and other blends. , while the proportion of polyester-cotton in polyester is as high as about 70%, that is, the stock is as high as 8.4 million tons / year. However, due to the difficulty in recycling polyester-cotton blended fabrics, most of them have not been effectively recycled, resulting in a huge amount of waste textiles , not only pollute the environment, occupy a large amount of storage space, but also cause a great was...

Problems solved by technology

[0005] In order to solve many deficiencies of existing devices in the separation of components of waste polyester-cotton blended fabrics, the present invention provides a device for separating components of waste polyester-cotton blended fabrics using a horizontal rotary alcoholysis kettle. The device utilizes a horizontal inner cylinder to rotate Material mixing effectively solves the problems of solid (cotton fiber) components being entangled, stirred and difficult to discharge.
