A two-way magnetic projection automatic separation device for plastic waste

Abstract

The invention provides an automatic bidirectional magnetic projection separation device for plastic waste, which includes a separation box for holding a medium solution; a feeding mechanism and an axially magnetized annular magnet group arranged between the feeding mechanism and the separation box; The mechanism includes a feed channel through which the discharge end passes through the ring magnet group and communicates with the separation box, and a pendulum that is slidably arranged in the feed channel and can push the materials in the feed channel to the separation box; the end surface of the discharge end of the feed channel and the ring The direction of the central axis of the magnet group is vertical; the end surface of the pushing end of the pendulum has a profile structure consistent with the end surface of the discharging end; the center of the end surface of the discharging end is close to or located at the central axis of the ring magnet group. The automatic separation device of the present invention has high separation accuracy, high separation recovery rate, large single separation amount, and can separate a mixture of various plastic wastes, greatly improving work efficiency and reducing separation cost.

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.
