Description

Technical Field

[0001] The utility model relates to the technical field of plastic masterbatch magnetic separation, in particular to a plastic masterbatch magnetic separation device. Background Art

[0002] In the process of plastic processing and molding, for the convenience of operation, the required various additives, fillers and a small amount of carrier resin are first mixed and kneaded. The granular material obtained through the process of metering, mixing, melting, extrusion, pelletizing and other processing by extruders and other equipment is called plastic masterbatch. During the processing of plastic masterbatch, the screw is often worn, the moving knife is broken, and there are iron filings or other metal particles in the raw materials, which leads to powdery and granular ferromagnetic impurities in the plastic masterbatch. In order not to affect the use of plastic masterbatch, the powdery and granular ferromagnetic impurities in the plastic masterbatch need to be separated from the plastic masterbatch.

[0003] Announcement No. CN214982382U discloses a magnetic separation mechanism for plastic masterbatch, which is convenient for rotating the plastic masterbatch and performing subsequent magnetic separation operations. The iron filings in the plastic masterbatch are collected by a magnet, which is convenient for cleaning and improving the production quality of the plastic masterbatch. However, when the magnetic separator is used, the plastic masterbatch is thrown on the magnetic suction plate to absorb magnetic impurities. After absorbing a certain amount of magnetic impurities, the magnetic suction plate will have a certain decrease in the adsorption force of subsequent magnetic impurities. Therefore, the plastic masterbatch and the magnetic impurities that fall on the magnetic suction plate are ejected due to the rebound effect, resulting in leakage of the screen, thereby causing the quality of the plastic masterbatch at the screening location to decrease. To this end, we propose a magnetic separation device for plastic masterbatch. Utility Model Content
