Device for removing iron-containing impurities from plastic raw materials

Abstract

The invention discloses a device for removing iron-containing impurities from plastic raw materials. The device comprises a housing, wherein a feeding hole is formed in the upper end of the housing; ahorizontal support plate is fixedly connected between the left and right inner walls of the housing; rotary doors are rotatably connected onto the left and right side walls of the housing and are correspondingly mounted on the upper side of the support plate; two parallel sliding chutes are formed in the upper end of the support plate; two U-shaped blocks are connected between the two sliding chutes in a sliding manner; conical magnets are fixedly connected with the upper ends of the U-shaped blocks; a plurality of discharging holes communicating with each other up and down are formed in thesupport plate and surround the outer sides of the conical magnets; two material guiding hoppers are fixedly connected with the lower end of the support plate; and the material guiding hoppers are correspondingly mounted on the lower sides of the discharging holes. The device can remove the iron impurities in the plastic raw materials in a dual manner and increases the iron removing rate of the plastic raw materials; and the iron impurities after iron removal facilitate following treatment.

Description

technical field [0001] The invention relates to the technical field of cleaning plastic raw materials, in particular to a device for cleaning iron-containing impurities in plastic raw materials. Background technique [0002] The currently used plastic raw materials are purchased from outside. The plastic raw materials contain a large amount of iron impurities. The iron content of the plastic raw materials is too high, which affects the product quality. Therefore, the plastic raw materials should be cleaned to reduce the iron content. At present, iron-containing impurities in plastic raw materials are mostly removed by magnet adsorption. When the plastic raw materials pass through the screen, the removal of impurities is completed after the adsorption of the magnets in the screen. The iron removal method of the existing device is relatively simple, the iron removal rate is low, and the iron impurities after iron removal are not convenient for later treatment; therefore, it is...
