Electrolytic aluminum waste magnetic separation equipment

Abstract

The invention relates to electrolytic aluminum waste magnetic separation equipment, and belongs to the technical field of electrolytic aluminum waste recovery. The equipment comprises a magnetic separation cylinder, wherein a magnetic separation roller and an overturning roller are rotatably connected between two vertical side walls of the magnetic separation cylinder, an arc-shaped first supportplate is fixedly connected to the inner wall of the magnetic separation cylinder, an arc-shaped second support plate is slidably connected to the magnetic separation cylinder, a material clearing knife is fixedly connected to the end, away from the overturning roller, of the first supporting plate, one end of the material clearing knife makes contact with the side wall of the magnetic separation roller, a first material box used for containing iron impurities is arranged under the material clearing knife, a second material box used for containing carbon particles is arranged under the overturning roller, a feeding port is formed in the upper end face of the magnetic separation cylinder, waste enters the magnetic separation cylinder through the feeding port, the overturning roller turns over the waste to guarantee that the waste makes full contact with the magnetic separation roller, the iron impurities on the magnetic separation roller are removed through the material clearing knife, the removed iron impurities fall into the first material box along the material clearing knife, and the second supporting plate is pulled, so that carbon particles with the iron impurities removed arepushed into the second material box.

Description

technical field [0001] The invention relates to the technical field of recycling electrolytic aluminum waste, in particular to a magnetic separation device for electrolytic aluminum waste. Background technique [0002] The anode of the electrolytic aluminum plant is a consumable product. The electrolytic aluminum plant will eliminate a batch of waste electrodes every time it works for a period of time, which is called the residual electrode. After being broken, it becomes granular and powdery electrolytic aluminum waste. The main components of these waste materials are carbon. It is the anode of the used electrolytic cell, which can no longer be used for its original purpose, but it can be used as an aggregate for the production of carbon anode after crushing and other processing, and can also be used as fuel for combustion. But a certain amount of electrolyte (iron impurity) mixed in these residual pole residues reduces its use value. [0003] People reclaim carbon block ...

AI Technical Summary

Problems solved by technology

Due to the different sizes of carbon particles produced when the residual slag is broken, powder will also be produced. Whether it is manual sorting or jig sorting, when the particle diameter of the carbon block is too small or powdery, the picking efficiency is very low. At the same time, the labor intensity of the staff is also very high
