Problems solved by technology

In the recycling of PET bottles, since most of the batch cleaning adopts slice cleaning, metal separation can be selected in the slice cleaning process. At present, there is no effective automatic method to realize the automatic separation of metal impurities in PET slice materials.

Abstract

The invention relates to a metal separation device special for PET bottle grades. The metal separation device comprises a feeding hole, a magnet, a transparent connecting band, an impurity channel, a PET bottle grade channel, a PET bottle grade outlet and an impurity outlet. A charged object is subjected to action of Lorentz force in the process of moving in a magnetic field so as to change the motion direction, so that the charged PET bottle grades are separated from an uncharged metal material area, and thus an aim of separating the metal impurities is achieved. The action of the Lorentz force is fully utilized, so that the charged PET bottle grades to be separated drop in a PET bottle grade channel in a non-perpendicular direction under the action of the magnetic field, the metal impurities are completely removed, the problem that the separation operation is incomplete because the metal materials are separated through a magnet is solved, and the detection rate of the metal impurities in the materials is improved to the greatest degree.

Description

Technical field [0001] The invention relates to the field of PET bottle recycling, in particular to a special metal separation device for charged PET bottle flakes. Background technique [0002] Polyester fibre (polyester fibre) is a synthetic fibre obtained by spinning polyester formed by polycondensation of organic dibasic acid and diol. Industrialized mass-produced polyester fiber is made of polyethylene terephthalate, and the Chinese trade name is polyester. It is currently the largest variety of synthetic fibers. Polyethylene terephthalate is the most important type of thermoplastic polyester. The English name is Polythylene terephthalate, referred to as PET or PEIT (hereinafter referred to as PET), commonly known as polyester resin. It is a condensation polymer of terephthalic acid and ethylene glycol. Together with PBT, it is collectively referred to as thermoplastic polyester, or saturated polyester. PET is divided into fiber-grade polyester chips and non-fiber-grade p...
