A vertical eddy current sorting device

Abstract

The invention discloses a vertical-type vortex sorting device. The vertical-type vortex sorting device comprises a rotary shaft arranged in the perpendicular direction. A magnetic roller is fixed to the rotary shaft, a rotary shaft driving unit is arranged below the rotary shaft, and a separation unit is arranged on the outer side of the magnetic roller and comprises an inner separation plate, an outer separation plate and a partition plate which are arranged in the perpendicular direction. A feeding port is formed above the outer separation plate, and an arc plate is arranged below the feeding port; and one end of the arc plate is arranged below the feeding port, and the other end of the arc plate is arranged between the partition plate and the inner separation plate. The tangent line of an arc plate at a material outlet is in the horizontal direction; and a non-metal receiving groove is formed below the inner separation plate and the partition plate, and a metal receiving groove is formed below the outer separation plate and the partition plate. The vertical-type vortex sorting device has the advantages that (1) the vortex force action time is long; (2) materials cannot be mutually squeezed in the separation process, material particles are independent, and the separation effect is better; and (3), the structure is simple, and no noise exists.

Description

technical field [0001] The invention relates to the field of machinery, in particular to an eddy current separator, which is mainly aimed at the separation and extraction of crushed electronic waste. Background technique [0002] With the rapid development of my country's economy and society, the use of electrical appliances has achieved rapid popularization for civilian use and even household use in my country. The electrical appliances used have also gradually realized speed and miniaturization from large and heavy equipment. These devices that use electric current or electromagnetic fields to work are called electronic and electrical products, including household appliances, communication equipment, office accessories, etc. Electrical and electronic products have a finite lifespan due to the wear and tear of components during use. End of life reached, function lost. These "e-waste". The metal contained in it has a high taste and a huge quantity, which is of great recy...

AI Technical Summary

Problems solved by technology

Since the attenuation of the magnetic field in the space around the magnetic roller changes exponentially, the strength of the peripheral magnetic field is almost zero, and the particles have a certain horizontal initial velocity when they are fed, so the metal is subjected to eddy current force for a short period of time, and cannot fully accelerate the movement, thereby affecting The sorting effect is improved;

[0006] (2) The conveyor belt is easily damaged

Generally speaking, the more stable the conveyor belt is, the better, because the metal smelt and non-metallic residues are prone to vibration during the process of moving with the conveyor belt, and then enter between the conveyor belt and the magnetic roller, which increases the wear of the conveyor belt and the magnetic roller. Increase the friction coefficient on the surface of the conveyor belt, which is not conducive to the separation of materials;

[0007] (3) Particles are easy to deviate

[0008] (4) There is a problem of material leakage

[0009] (5) There are more collisions

During the throwing process of the particles, there will be a certain interference between the particles, and there is a possibility of collision between the particles and the sealing cover above the receiving trough

[0010] (6) Problems of noise and vibration

During the sorting work, the vibration and noise of the device are relatively large, especially the motors of the conveyor belt and the magnetic roller have the problem of swinging from side to side

[0011] (7) Inconvenient to carry

The weight of the currently designed device is about 70kg, which is too large for portable equipment; coupled with the existence of the conveyor belt, the volume of the device is also too large
