Bidirectional magnetic projection automatic separation device for plastic waste

Abstract

The invention provides a bidirectional magnetic projection automatic separation device for plastic waste. The bidirectional magnetic projection automatic separation device comprises a separation box used for containing a medium solution. the bidirectional magnetic projection automatic separation device further comprises a feeding mechanism and an axial magnetizing annular magnet group, the axial magnetizing annular magnet group is arranged between the feeding mechanism and the separation box, the feeding mechanism comprises a feeding channel and a pendulum bob, wherein the discharging end of the feeding channel penetrates through the annular magnet group and communicates with the separation box, the pendulum bob is arranged in the feeding channel in a sliding mode and can push materials in the feeding channel to the separation box, the end face of the discharging end of the feeding channel is perpendicular to the central axis direction of the annular magnet group, the end face of the pushing end of the pendulum bob is of a molded surface structure consistent with the end face of the discharging end, and the center of the end face of the discharging end is close to or located on the central axis of the annular magnet group. The bidirectional magnetic projection automatic separation device is high in separation precision, high in separation recovery rate and large in single-time separation amount, a mixture of various plastic wastes can be separated, the working efficiency is greatly improved, and the separation cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of separation of plastic waste, and in particular relates to a bidirectional magnetic projection automatic separation device for plastic waste. Background technique [0002] Plastic is widely used in daily life and industrial production because of its advantages of easy shaping, light weight, high fatigue strength, and corrosion resistance, but it also generates a lot of plastic waste. At the same time, plastic waste is usually characterized by a high degree of mixing, various types, and large quantities, making it difficult to recycle reasonably and efficiently. The high cost of separation of plastic waste and low separation efficiency are the main difficulties in the recycling of plastic waste. [0003] In order to deal with the separation and recycling of different plastics, there are currently more discussions on foam separation, hydrocyclone separation and electrostatic separation. The froth flotation...

Problems solved by technology

[0005] However, the single separation volume of the above-mentioned separation device is small. When the separation volume is large, the initial movement points of all wastes in the sample delivery channel are different due to the horizontal repulsion force of the magnet, resulting in a decrease in separation accuracy, which cannot meet the separation needs of large quantities of plastic waste.
