Description
Technical field
The utility model relates to magnetic separator equipment technical field, specifically, relates to a kind of electromagnetism and eluriates refiner.
Background technology
Assorted approach raising concentrate grade falls in magnet ore dressing plant equipment by putting forward essence mainly contains conventional type permanent-magnet drum type magnetic separator, magnetic accumulating machine, column magnetic separator, elutriation magnetic separator.But these magnetic plants existing more or less existing defects: conventional type permanent-magnet drum type magnetic separator exists obvious magnetic coagulation phenomenon in refining process, improves concentrate grade limited extent; Magnetic accumulating machine magnetic field is constant, can not adapt to different ore properties and concentrate grade requirement, and there is defects such as running tail height; The a whole set of magnet exciting coil of column magnetic separator often changes one-period, and its overflow area, top just exists without magnetic region, easily causes overflow mine tailing Armco magnetic iron grade higher, affects the concentrate rate of recovery.
Elutriation magnetic separator is a kind of by synergy such as magnetic force, gravity, buoyancy and centrifugal force, by the cooperation control to electromagnetism magnetic system, electric current, current, concentration, a kind of integrate power field is formed in elutriation magnetic separator inside, reject intergrowth and the gangue mineral of fine fraction impurity and thicker level through flushing water, thus smart iron ore is effectively purified.Elutriation magnetic separator is a kind of magnetic iron ore picking equipment efficiently, puies forward essence and falls general labourer's journey and contribution has been made in technique of preparing progress, create larger economic benefit for magnetite separation factory.
Existing elutriation magnetic separator comprises the washing cylinder be made up of inside and outside cylindrical shell, inner barrel is communicated with the mine tailing overflow launder that top droop is arranged, cylindrical dispenser is provided with above overflow launder, dispenser side is communicated with feed pipe, dispenser bottom arranges material blanking tube along washing cylinder axis, between inside and outside cylindrical shell, magnet exciting coil is set, the concentrate outlet being communicated with inner barrel is set bottom magnetic separation barrel, circular water inlet ring around washing cylinder is set bottom washing cylinder, water inlet ring inside, connection inner barrel, arrange water inlet pipe along water inlet ring inner chamber tangential direction.During work, ring water is tangentially fed by bottom, magnetite powder feeds washing cylinder by dispenser, sorting district is entered after scattering, by the control to magnetic system, magnet exciting coil is made to produce alternately excitation field in point constituency, ore particles is under the integrate power field effect replacing the power such as excitation field, gravity, buoyancy, centrifugal force and ascending water impulse force, gangue, namagnetic substance and intergrowth etc. are overflowed through overflow pipe by overflow launder, effectively reject the monomer gangue be mingled with in magnetic ore deposit and intergrowth, magnetic ore deposit is eluriated clean, magnetic ore deposit is discharged by concentrate pipe.
At present, though elutriation magnetic separator is a kind of magnetic iron ore picking equipment efficiently, puies forward essence for magnetite separation factory and fall general labourer's journey and contribution has been made in technique of preparing progress, create larger economic benefit.But in industrial practice, also find that it exists some defects and needs to improve further.Such as: the electromagnetism magnetic system top of existing elutriation magnetic separator adopts single fixing magnetic system control model, this conventional magnetic system arranges and the higher phenomenon of mine tailing Armco magnetic iron grade appears in control model in use sometimes, particularly to the higher concentrate of grade more further magnetic separation to upgrade or to when more fine fraction concentrate carries out selected, tailings grade is higher wayward.During use, the magnetic field intensity of fixed coil is generally all large than circulation magnetic field, compensating field.Under normal circumstances, be not recycled the vignite that magnetic field captures and can be flushed to fixed coil position by ascending current.Because the magnetic field intensity of fixed coil is comparatively large, most of magnetic iron ore can be adsorbed to fixed coil surface.Because fixed coil is in "on" position always, the ferromagnetic mineral adsorbed can be more and more thicker, is unfavorable for that the later stage continues absorption ferromagnetic mineral.
Simultaneously when the weight of ferromagnetic mineral of adsorbing is greater than the impulse force of the suction in magnetic field and ascending current, can along the overall landing of wash mill inwall, in the process of landing, because the environment that sorts of wash mill internal stability is destroyed, have iron ore mineral that are that major part is not come and knot chain to be gone out by ascending current, produce a property sent out to overflow, the intermittence of overflow liquid level is caused to fluctuate, overflow liquid level is unstable, also be unfavorable for effectively controlling tail simultaneously, cause mine tailing Armco magnetic iron content to increase, tailings grade raises, and the concentrate rate of recovery reduces.Therefore, only have the elutriation magnetic separator of a fixed coil control model, rationally effectively that tail is more difficult to some ore deposit, occur that tailings grade is higher, the concentrate rate of recovery reduces, and control understable, economic benefit is influenced,
The feed pipe diameter of the dispenser of current elutriation magnetic separator is thinner, general isometrical or be less than closed inner diameter of steel flue with closed inner core, due to from the separation tube diameter of axle more close to magnetic field intensity more weak, more not easily caught by magnetic field the closer to feed pipe Armco magnetic iron like this, Armco magnetic iron content in overflow mine tailing is caused to raise, therefore also cause tailings grade higher, the phenomenon that the concentrate rate of recovery reduces.In addition, after magnetite powder enters elutriation magnetic separator dispenser, directly overflowed by the material blanking tube of dispenser bottom, after material enters separation tube by this kind of mode, bulk cargo is owed evenly, to be unfavorable for the selected operation of elutriation magnetic separator to concentrate.
In addition, it is large also to there is water consumption in elutriation magnetic separator, affects the problems such as selected effect during feed fluctuation.
