Technical Field

The invention belongs to the technical field of non-ferrous metal (copper, aluminum, zinc and the like) eddy current sorting equipment, and particularly relates to a belt cleaning device for an eddy current sorting machine.

Background

The equipment applied to the field of non-ferrous metal recovery in the market at present generally uses an eddy current separator, and materials to be separated are conveyed to a high-speed magnetic roller end through a conveying belt, and a high-speed changing magnetic field is formed by utilizing a permanent magnet when rotating at a high speed, so that eddy current is generated on the surface of metal when the metal with good conductivity passes through the magnetic field, the magnetic field generated by the eddy current is opposite to the background magnetic field, repulsion force is formed, and the metal is separated from the materials and enters a material separating box. While the remaining tailings fall into the sand outlet (as shown in figure 1).

Because the on-spot operating mode of equipment, material are different, and in the actual production, the tails after selecting separately will partly glue on the transmission band, along with the circulation operation of transmission band and the material of waiting to select separately mixes, and in cycles, the increase of tails thickness can directly influence the magnetic field that the magnetic roll used the material, makes the metal jump height that electric conductivity is good low to select separately the effect variation. Therefore, the degree of belt cleaning has a great influence on the sorting rate of the vortex sorting machine.

The mode of solving vortex sorter transmission band adhesion material, keeping the transmission band cleanliness in the existing market has two kinds:

an active cleaning device;

install the roller that cleans of nylon (or other) material additional in the below of vortex separator transmission band, vortex separator support body both ends symmetry installation bearing frame and bearing frame support will clean the roller both ends and install respectively on the bearing frame, and the one end of cleaning the roller is passed through the shaft coupling and is cleaned the roller motor and link to each other, realizes the initiative rotation and reaches the purpose of cleaning the transmission band. However, the active cleaning device needs to be additionally provided with a motor as a power source of the active cleaning device, so that the equipment cost, the later maintenance cost and the loss of electric energy are increased. The transmission belt of the vortex separator is subjected to the external force action of the active cleaning device, so that the transmission belt can be deviated.

Fixing the cleaning device:

the cleaning roller or scraper made of nylon (or other) materials is additionally arranged below the conveying belt of the vortex separator, the cleaning roller or scraper is arranged on the cleaning roller supports symmetrically arranged at two ends of the vortex separator frame body, and the purpose of cleaning the conveying belt is achieved by utilizing the relative motion between the conveying belt and the cleaning roller. The transmission belt of the fixed cleaning device is slow in running speed, wet tailings or tailings with high viscosity are easy to accumulate in the brush of the cleaning roller, a mud rod is formed for a long time, the cleaning effect is greatly reduced, and the replacement period of the cleaning roller is shortened.

If a scraper is used, the bonded tailings are accumulated on the scraper and are easy to condense, so that the conveying belt can be scratched, and the service life of the conveying belt is shortened.
