Description

The centrifugal magnetic separator of a kind of permanent magnetism
Technical field
The utility model relates to the magnetic mineral screening installation, relates in particular to a kind of centrifugal magnetic plant of permanent magnetism that reclaims the micro-size fraction magnetic material.
Background technology
Fine-particle minerals raw material recovery technology is the difficult problem of ore dressing circle always.Along with the poor refinement of mineral resources and carrying out and implementing of smelter " fine fodder policy ", need the fine-particle minerals raw material of ore dressing recycling more and more, particularly to measuring the recycling of big, inexpensive magnetic (ferromagnetism, middle magnetic or weak magnetic) fine-particle minerals raw material.At present, industrial sorting to micro-size fraction magnetic mineral raw material is reclaimed and is mostly adopted drum magnetic separator or centrifugal ore separator, but because drum magnetic separator is subjected to the restriction of device structure form, magnetic is that cornerite generally can only reach 90 °-135 °, therefore, generally can only adopt 3-6 level magnetic system, the magnetic separation material can only roll 3-6 time in the magnetic separation process, be unfavorable for that the non-magnetic material that will be mixed in wherein separates, in addition, adopting drum magnetic separator when sorting mined material, is that ore pulp is given in the sorting groove, magnetic material is taken out of liquid level by cylinder, the water flushing enters in the magnetic material material-receiving device after breaking away from magnetic field force, and non-magnetic material is along with ore pulp flows into the non-magnetic material mine-carrying groove, because the amount of ore pulp is big, cause very big impulsive force, make that the micro-size fraction magnetic material rate of recovery is low.Centrifugal intensity changes between surplus in the of ten times even over one hundred times in the existing centrifugal reselection machine, the mass force of particle is greatly improved, but along with granularity descends, simple dependence mineral difference of specific gravity deficiency is so that different minerals obtains good sorting, and mineral closely knit in the wall sedimentation under strong centrifugal action, lack suitable shatter value and remove the gangue mineral that is mingled with, so centrifugal ore separator exists usually shortcomings such as concentration ratio is low, disposal ability is less, interruption work.
Summary of the invention
The purpose of this utility model is to provide the centrifugal magnetic separator of permanent magnetism that is used to reclaim the micro-size fraction magnetic material that a kind for the treatment of capacity is big, the rate of recovery is high.
The technical solution of the utility model is: the centrifugal magnetic separator of permanent magnetism is made up of parts such as magnetic conduction urceolus, outer shroud magnetic system, sorting rotating cylinder, rinsing device, charging gear, magnetic material discharge bucket, non-magnetic material discharge bucket, transmission device, rotating cylinder slope conditioning, frames.The magnetic conduction urceolus is fixed on the underframe, outer shroud magnetic system is around the inwall that is fixed on the magnetic conduction urceolus, the stage casing of sorting rotating cylinder is sheathed in the magnetic conduction urceolus and by being installed in that carrying roller on the underframe supports and by the transmission device driven rotary, the rotation end and the frame of underframe are hinged, end is supported on the frame by the rotating cylinder slope conditioning in addition, rinsing device and charging gear place in the sorting rotating cylinder, and magnetic material discharge bucket and non-magnetic material discharge bucket lay respectively at the both sides of sorting rotating cylinder.
The magnetic patch of the outer shroud magnetic system N-S level cross arrangement that equidistant line in the shape of a spiral distributes more than at least 2 combines.Sorting rotating cylinder tube inner surface magnetic field intensity is 2000-8000mT.
Be provided with rib strip shaped screw unloading plate at the sorting rotating cylinder near on the inwall of magnetic material discharge bucket end.
The rotating cylinder slope conditioning is made of height-adjustable adjustable screw mandrel or contract piece.
Rinsing device is the pipeline or the containers of discharging the water hole more.
Non-magnetic material goes out that ore bucket and magnetic material go out that being shaped as of ore bucket prevents that ore pulp from flashing and the bottom is taken the end cap of ore deposit mouth out of, also can be the semi-ring lid that the bottom is taken the ore deposit mouth out of.
The advantage that the utlity model has is: (1) is because the sorting rotating cylinder adopts the adjustable horizontal type structure of the gradient, magnetic force and action of centrifugal force have been made full use of, sorting material flows through in the sorting rotating cylinder that is similar to pipeline, is in all the time in the magnetic field, has strengthened sorting organic efficiency.(2) because the spiral magnetic architecture that adopts is 360 ° of disk pack angles, and magnetic material can roll in the magnetic separation process tens times, on same equipment, have simultaneously roughly select, selected or scan effect, and reduced the magnetic patch consumption significantly, reduced manufacturing cost.
