Description
Technical field
The present invention relates to a kind of separation equipment of Magnetic Materials, be specifically related to a kind of dry type sorting mineral enrichment plant.
Background technology
The wet magnetic separation method extensively adopting at present has adverse current type, half adverse current type and downstream-type magnetic separation technology, its grading principle schematic diagram is as shown in accompanying drawing 1, accompanying drawing 2, accompanying drawing 3, ore pulp feeds from feed launder, naturally flow in sorting groove, when ore pulp flows in Guide canel sphere of action, magnetic mineral particle is reunited and is adsorbed in drum surface rapidly under magnetic fields, and takes field regions out of with the rotation of cylinder, enters Magnetic Materials hopper and discharge magnetic separator under the edge in magnetic field is hit water effect.Part non magnetic ore has little time to enter with flow of slurry the aggregate that mine tailing just forms by magnetic mineral and tightly wraps up, and under limited Guide canel effect, the upset effect of magnetic system cannot fully remove nonmagnetics, therefore causes being generally mingled with of magnetic separation process.
Magnetic architecture and wet type for dry type magnetic separation are basic identical, but body structure is relatively simple, and Magnetic Materials enters behind magnetic field and is hunted down and is close to drum surface, and under the high speed rotating effect of cylindrical shell, Magnetic Materials departs from magnetic fields and enters concentrate store under effect of inertia; Mine tailing enters tailing bin along the landing of ore discharge baffle plate, also has following defect, and, under limited Guide canel effect, the upset effect of magnetic system cannot fully remove nonmagnetics, therefore causes being generally mingled with of magnetic separation process.
Summary of the invention
The object of the invention is the problem and shortage for above-mentioned existence, a kind of rate of recovery, less dry type sorting mineral enrichment plant being mingled with that increases magnetic field cornerite scope, strengthening magnetic upset effect, improves Magnetic Materials is provided.
For achieving the above object, the technical scheme of taking is:
A kind of dry type sorting mineral enrichment plant, comprise frame, be arranged on housing and actuating unit in frame, in housing, be fixed with a cylindrical tube, between barrel outer surface and housing, form sorting mineral storage bin, in described cylindrical shell, be provided with the tubular magnetic drum that can around axis rotate coaxial with cylindrical shell, actuating unit drives magnetic drum to rotate, on magnetic drum, around 360 °, its axis, be provided with and be the alternation power magnetic system that the cycle changes, alternation power magnetic system rotates with magnetic drum, between described sorting mineral storage bin top and cylindrical shell, along axis direction, be provided with demarcation strip, sorting mineral storage bin bottom is provided with inverted V-shaped and divides a plate, demarcation strip and a minute position plate are divided into concentrate store and tailing bin by sorting mineral storage bin, tailing bin top is material inlet, in the bottom of concentrate store and tailing bin, be respectively equipped with concentrate discharge port and mine tailing discharge port, at fine fodder Cang Chu, be also provided with impulse magnetic field generator.
Described alternation power magnetic is on magnetic drum, and around 360 ° of paired, to intersect, evenly the arrange N utmost point and S utmost points of magnetic drum axis, the adjacent N utmost point and the S utmost point form the alternation power magnetic system that one-period changes.
The adjacent N utmost point and the S utmost point, in the alternation power magnetic system of its single cycle variation, the maximum magnetic field strength of the N utmost point is 850Gs-4500Gs, the maximum magnetic field strength of the N utmost point is compared with more than the large 100Gs of the maximum magnetic field strength of the S utmost point.
Adopt technique scheme, obtained beneficial effect is:
1. the alternation power magnetic in the present invention is characteristics design, guaranteed field intensity intensity dynamic change along with the rotation of alternation power magnetic system of drum surface any point, be attached to the needle-like magnetic aggressiveness of drum surface along with the fluctuation in magnetic field is reunited rapidly loose, along the continuous flip-flop movement of drum surface, the non magnetic ore constantly needle-like magnetic aggressiveness of passive movement is dished out, so the present invention efficiently solves traditional magnetic separation process and is mingled with nonmagnetics problem.
2. magnetic concentrate technical indicator has a more substantial increase; The design of the N utmost point and S pole field strength difference, make needle-like magnetic aggressiveness under magnetomotive traction along being that the direction that the direction of motion is contrary is moved with magnetic, the whole motion process of Magnetic Materials completes under magnetomotive traction, so drum surface is relatively smooth, weares and teares less.
3. traditional drum magnetic separator Magnetic Materials is tightly attached to drum surface after reuniting, and under cylindrical shell motion effect, by force mineral is pulled out to magnetic field, and the friction of mineral and drum surface is comparatively serious, and therefore wearing and tearing are larger.Middle cylinder body transfixion of the present invention, needle-like magnetic aggressiveness is arranged in liquid environment (wet type) and is suspended in drum surface, and the life that the mode of magnetomotive traction is better than mechanism is greatly dragged firmly and is dragged, and reduces wear and increases the service life.
4. the alternation power magnetic in the present invention is that the magnetic cornerite that acts on Magnetic Materials is far longer than 360 °, under the effect of alternation power magnetic system, during magnetic drum rotating 360 degrees, Magnetic Materials only can be along the circumference of contrary direction rotation 1/4th, Magnetic Materials rotates and within one week, is equivalent to be subject to the magnetic cornerite active force of 4 weeks, although and conventional also can be larger compared with its magnetic cornerite, it is loose that the present invention carries out reuniting fully in the magnetic cornerite of practical function, thereby reach the object of removal of impurities.
