Description
Technical field
The invention belongs to the dry-type magnetic extractor field, be applicable to the sorting of industry magnetic minerals after the milling equipment grinding such as metallurgy, mine, chemical industry, but according to material solution grain situation sorting finished product or semi-finished product, especially application diameter is less than the sorting of the pulp of 1mm.
Background technology
Utilize the difference of mineral grain magnetic, sorting in magnetic field is the method that the magnetic material sorting is adopted usually.Wet magnetic separator needs water as working media, can't use in the water-deficient area, and may cause environmental pollution, be unworthy promoting, thereby dry type magnetic separation has obtained development faster in recent years.The conventional dry magnetic separator catches the magnetic mineral particle by the direct attraction in magnetic field, but causes the mineral recovery rate that sorts not high because solid accumulation thickness, magnetic system pollutes and the reason such as is mingled with, and becomes therefore improve the rate of recovery of magnetic mineral the subject matter that magnetic separation faces.For this reason, many solutions have been proposed in the industry.
A kind of wind-suction type permanent magnetism ore concentrate machine of Chinese patent CN201220178917.7 application, comprise charging aperture, dry type magnetic separation device, tailing storehouse and feed bin, the cavity inner roof wall of described dry type magnetic separation device is obliquely installed, and at the port of export of dry type magnetic separation device, air extractor is installed; Be disposed with the first magnetic roller group and the second magnetic roller group along the pan feeding direction in the cavity of dry type magnetic separation device.
A kind of oscillatory type high-performance magnetic separation machine of Chinese patent CN201220367847.X application comprises left socle, right support and conveyer belt, and left socle, right support are connected by link; Described left socle one end is provided with can be to the magnetic separation roller of magnetisable material absorption, and right support one end is provided with the driving runner that orders about the driving-belt motion, drives runner and is connected with Power Drive Unit; Be provided with the magnetic vibration device that is positioned at the driving-belt below on described link.
A kind of dry-type magnetic extractor of Chinese patent CN201210043655.8 application, comprise conveyer belt, conveyer belt is divided into feeding section and magnetic separation section, magnetic separation section inboard arranges magnetic, the magnetic separation section is followed successively by the section of roughly selecting, selected section of circular arc and concentrate feeding section along flow direction of material, and below the section of roughly selecting, correspondence arranges the inflatable shaking chute.
Suchlike solution is also a lot, does not enumerate at this.Summary is got up, and solution namely adopts wind-force, vibration or the mode of movement that both has concurrently fully is exposed under magnetic system it, thereby reaches the purpose that improves the magnetic mineral rate of recovery.
Compared to the conventional dry magnetic separator, above-mentioned solution makes the rate of recovery of mineral be enhanced, but still exists the undesirable problem of grade that reclaims mineral.Canvass its reason, mainly only as a kind of carrying capacity because of the wind-force in above-mentioned solution, magnetic material only has gravity and vibration force and magnetic force competition in sorting process, and the characteristic of particulate magnetic material makes the mineral that sort out exist more parcel and be mingled with, thereby causes the undesirable problem of mineral grade.
Summary of the invention
The object of the invention is to: provide a kind of and can improve the magnetic mineral rate of recovery and grade, dry-type magnetic extractor concentration equipment that sorting power is adjustable.
The object of the invention realizes by following technical proposals:
A kind of dry-type magnetic extractor concentration equipment, comprise and be provided with air inlet, and the non-magnetic closed air cavity of some air-vents, described some air-vents are located at the working face of described air cavity, comprise that also its magneticaction force direction with the magnetic of the opposite setting of described air cavity working face air-out direction is, and with so that the vibrating device of described air cavity vibration, described air cavity and magnetic are relative motion, and the direction of motion is that the magneticaction force direction is vertical with described magnetic.
As optimal way, described magnetic is uniform two or more sets permanent magnets or electromagnet, and the two adjacent groups magnetic pole is opposite.
As optimal way, described air cavity and the magnetic relative rotation of system or relative translation.
In such scheme, the relative rotation of system of air cavity and magnetic or relative translation are moved one quietly as one, or one fast one wait slowly with the formation relative motion.
As optimal way, described air cavity and magnetic are that movement velocity is controlled.
As optimal way, described air cavity working face air-vent single hole diameter 0.5～200 μ m, percent opening be greater than 1%, air permeance resistance 200Pa～3000Pa, and roughness is greater than 6.3 μ m.
As optimal way, described air cavity air inlet cut-in pressure gas, gas pressure 〉=400Pa.
As optimal way, described magnetic is to be located in described air cavity.
As optimal way, described magnetic is to be located at the outer side opposite to described air cavity working face of described air cavity, is the corresponding magnetizing mediums that is fixed with magnetic in air cavity.
The course of work is: material to be selected is positioned at concentration equipment working face side, is sprayed by air inlet access gas and the air-vent from working face in air cavity.When air cavity or magnetic system moved through material to be selected, magnetic force was adsorbed onto magnetic material and parcel thereof, field trash the working face of air cavity bottom, and non-magnetic material is admitted to the mine tailing mouth.At this moment, be adsorbed on the effect that material on working face is subject to magnetic force, gravity, wind-force and vibration force, magnetic material continues to be adsorbed on working face because of magneticaction, and non-magnetic material falls and be admitted to the mine tailing mouth from working face under gravity, wind-force and vibration force effect.Along with air cavity or magnetic are mobile, because two adjacent groups magnet polarity is opposite, repeatedly upset occurs in the material that is adsorbed on working face, the non-magnetic material that is mingled with or is wrapped in magnetic material continues to be subject to the effect of wind-force, gravity and vibration force in switching process and falls and be admitted to the mine tailing mouth from working face, and magnetic material continues to be adsorbed on working face and is brought to the concentrate mouth and takes off magnetic and fall into the concentrate mouth in gravity, wind-force and vibration force effect.
Beneficial effect of the present invention: the present invention has changed the action direction of magnetic separator wind-force in the past, make magnetic material wind-force when sorting participate in competition with magnetic force, thereby greatly improved the rate of recovery and the grade of magnetic material, changing magnetic field makes this effect further promote simultaneously.
