Plastic particle feeding magnetic separation groove

Abstract

The invention discloses a plastic particle feeding magnetic separation groove. The plastic particle feeding magnetic separation groove is arranged in the middle of a plastic particle feeding mechanism. The plastic particle feeding magnetic separation groove comprises a chute body and a magnetic separation mechanism. The chute body comprises a chute bottom, a chute wall and a chute cover. The magnetic separation mechanism is fixed on the chute walls on the two opposite sides of the chute. A particle inlet pipe is arranged at the head position of the chute. A particle suction pipe is arranged atthe tail of the chute The bottom of the chute is inclined along the direction of particle movement. An electromagnetic oscillator is arranged at the bottom of the chute. The magnetic separation mechanism comprises a magnetic roller, a scraper groove and a particle brush. The scraper of the scraper groove is tightly attached to the surface of the magnetic roller, and the brush surface of the particle brush passes through the contact line between the scraper and the magnetic roller. With application of the mode, omission in the magnetic separation process can be reduced and the selected particles can be quickly removed through the scraper groove.

Description

technical field [0001] The invention relates to the field of production equipment, in particular to a magnetic separation tank for feeding plastic particles. Background technique [0002] In the production process of plastic particles, metal impurities are occasionally mixed in the particles due to various reasons. In order to prevent the metal impurities from affecting the quality of the product, plastic particles are generally mixed in the feeding process when plastic particles are bagged or used as raw materials for production. Add a magnetic separation screen, but the commonly used magnetic separation screen generally has a fast particle passing speed, and the particles adhering to the magnetic separation screen cannot be removed until the feeding is completed, and sometimes they will be brought back into the feeding pipeline. Contents of the invention [0003] The technical problem mainly solved by the present invention is to provide a magnetic separation tank for pla...
