Technical Field

The invention belongs to the technical field of nonferrous metal 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 the end of a high-speed magnetic roller through a 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-site operating mode of equipment, material are different, and in actual production, the tailings after the separation can partially stick on the belt, and along with the circulation operation of belt and the material of waiting to sort mix, go round and over again, the increase of tailings 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 it is poor to select separately the effect. Therefore, the degree of belt cleaning has a large effect on the sorting rate of the vortex sorter.

The mode of solving vortex sorter belt adhesion material, keeping belt cleanliness in the existing market has three kinds:

cleaning device that the motor directly links:

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. Because of cleaning the roller and rubbing with the belt for a long time, can cause the wearing and tearing of cleaning roller brush hair, so cleaning the roller and will adjust the height through a period of time, just can keep with the contact of belt, at this moment, want the height of adjusting cleaning the roller, need adjust cleaning roller and motor simultaneously, complex operation, still need dismantle the motor when changing cleaning the roller moreover.

Belt-driven (chain-driven) cleaning devices;

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 belt or (chain) and is cleaned roller motor and overspeed device tensioner and link to each other, realizes the initiative rotation and reaches the purpose of cleaning the transmission band. The cleaning roller rubs the belt for a long time, so that the brush hair of the cleaning roller is abraded, the cleaning roller can be kept in contact with the belt after being adjusted in height after a period of time, at the moment, the height of the cleaning roller is adjusted, the cleaning roller and the tensioning device need to be adjusted at the same time, the operation is complex, the space limitation is large, and the cleaning roller is difficult to install on old equipment.

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.
