Embodiment Construction

[0012] The present invention will be further described below in conjunction with accompanying drawing.

[0013] Special metal separation device for PET bottle flakes, including feed inlet 1, magnet 2, transparent connecting belt 3, impurity channel 4, PET bottle flake channel 5, PET bottle flake outlet 6, and impurity outlet 7. It is characterized in that the impurity channel 4 is set on In the middle of the two PET bottle flake channels 5, the feed port 1 is set directly above the PET bottle flake channel 5 and the impurity channel 4 arranged side by side, and the transparent The connection belt 3 is connected, the magnet 2 is set in the front and rear directions of the feed port 1, the impurity channel 4, the PET bottle flake channel 5, and the feed port 1 have the same length, and the lower ends of the two PET bottle flake channels 5 are merged and connected on one side. On the PET bottle flake outlet 6, the impurity channel 4 is connected to the impurity outlet 7 on the ot...

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 PET bottle flakes. Background technique [0002] Polyester fiber is a synthetic fiber obtained by spinning polyester obtained by polycondensation of organic dibasic acid and dibasic alcohol. The polyester fiber produced in large quantities in industrialization is made of polyethylene terephthalate, and the trade name in China is polyester. It is the largest variety of synthetic fibers at present. Polyethylene terephthalate is the most important variety 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, and together with PBT, it is collectively referred to as thermoplastic polyester, or saturated polyester. PET is divided into fiber-grade polyester c...
