Summary of the invention
The technical problem to be solved in the present invention provides the permanent magnet dry type magnetic ore separator that a kind of magnetisable material separates with namagnetic substance thoroughly, equipment failure rate is low.
For solving the problems of the technologies described above, the present invention includes frame, its design feature is that the main shaft that is driven by spindle motor is installed on frame, is that gripper shoe is equipped with the compound magnetic system that rotates with main shaft by magnetic on the main shaft; The periphery that is at compound magnetic is equipped with cylinder, and cylinder is by the Rolling motor driving and with respect to the main shaft backwards rotation; On cylinder, be set with drum shaft to isometric ring-type material-conveying belt, the other end of material-conveying belt is supported by rack-mounted driven transfer roller; The top of material-conveying belt is equipped with the feed arrangement that has charging aperture, the below of material-conveying belt, along the material-conveying belt rotation direction nonmagnetics hopper, the magnetic material case that has discharging opening is installed side by side, feed arrangement, nonmagnetics hopper and magnetic material case are formed enclosure space jointly.
Described compound magnetic is to comprise the supporting disk that is supported on the main shaft, the outer radial periphery of supporting disk is equipped with some bar shaped gripper shoes, the concrete quantity of bar shaped gripper shoe is determined according to the supporting disk diameter, be installed with the permanent magnet blocks group on the outer peripheral face of every bar shaped gripper shoe, the radial outer end polarity of adjacent permanent magnet piece group is opposite.
On main shaft, the other end is connected with hollow wheel gear to described cylinder wall one end by bearings, and on main shaft, hollow wheel gear is connected with the tube motor power hollow wheel gear by bearings.
Form in the enclosure space jointly by feed arrangement, nonmagnetics hopper and magnetic material case, nonmagnetics hopper and magnetic material case intersection be equipped with the separation adjusting device, this separation adjusting device comprises and is supported on frame both sides and main shaft rotating shaft in the same way, along the shaft length direction separation dividing plate that stretches to material-conveying belt is installed, rotating shaft angular adjustment handle is installed in the frame outside of rotating shaft one end.
Described driven transfer roller comprises driven transfer roller and following driven transfer roller, and it is concordant with the cylinder end face to go up driven transfer roller end face, and following driven transfer roller bottom surface is lower than the cylinder bottom surface.
After adopting said structure, since separated material with in the material-conveying belt running under the effect of the compound magnetic system that rotates with main shaft, magnetisable material tightly is adsorbed on the material-conveying belt, and namagnetic substance " is squeezed " the material upper strata, and compound magnetic system and separated material backwards rotation, be convenient to effectively separating of magnetisable material and namagnetic substance, namagnetic substance is thrown to the nonmagnetics hopper under the effect of centrifugal force and gravity fast, and magnetisable material continues to move with material-conveying belt, after having the magnetic region, be not quickly discharged into automatically in the magnetic material case, so magnetisable material separates with namagnetic substance thoroughly; And the feeding device and the compound magnetic that are in the enclosure space are relative separation, and equipment failure rate is low.
The permanent magnet blocks group that constitutes compound magnetic system is divided into some bar shapeds, the radial outer end polarity of adjacent permanent magnet piece group is opposite, compound magnetic is tied up to its polarity of the magnetic field in the axle rotation process alternately to be changed fast, make the strong magnetic stirring of material generation on the material-conveying belt, magnetisable material constantly overturns in motion process, beats, and magnetisable material separates more thorough with namagnetic substance; To drive cylinder be backwards rotation with respect to compound magnetic by being arranged on hollow wheel gear on the cylinder wall, and its power transmission structure is simple; And the separation adjusting device is installed at nonmagnetics hopper and magnetic material case intersection, separating effect is better; Driven transfer roller is set to two, and driven transfer roller bottom surface is lower than the cylinder bottom surface down, is convenient to magnetisable material and is quickly discharged in the magnetic material case.
