Abstract
The utility model relates to a magnetic-gravity ore dressing machine with a low magnetic field, which is used for selecting magnetic iron ore, and the utility model is composed of a magnetic system which is composed of an ore feeding pipe, an overflow outlet and field coils, a sorting barrel, water supply pipes, a concentrate discharge pipe and a central control unit. The utility model is characterized in that a diameter of the overflow outlet is smaller than the sorting barrel, the field coils which form the magnetic system are oddly arranged, the utility model is provided with two water supply pipes which are respectively and symmetrically arranged at a lower part of the sorting barrel. The utility model has the advantages of multiple polymerization and separation of the sorting material in a low field strength, so magnetic mineral can be effectively separated from gangue and coenobium, magnetic inclusion can be reduced to a lowest limit, and the utility model has the advantages of low energy consumption and stable overflow quality and can be used for industrialize continuous production.
Description
The utility model relates to a kind of magnetic plant, and particularly a kind of magnetic iron ore that is used for comprises the downfield magnet-gravity ore machine that sorts based on all kinds of natural magnetites of ferromagnetism iron mineral and artificial magnet ore etc.
At present, several equipment such as " low-intensity (magnetic) separator ", " magnetic dewater cone " that domestic and international widely used magnetic iron ore picking equipment mainly is a cartridge type, " magnetic accumulating machine ", the magnetic system of these equipment mostly is permanent-magnet material and makes, inevitable with the higher intergrowth of a large amount of relative magnetic susceptibilities in the process of sorting like this, even wrap up in and take the monomer gangue and enter concentrate, thereby influence the sorting of mineral and sort precision.For addressing the above problem, the preparation equipment that Chinese patent 93228152.4 discloses a kind of " magnetic separation post ", though this equipment all is better than above equipment sorting on principle and the unit test index, water consumption is big, the overflow cycle " runs black ", overflow is of high grade, reduce defectives such as the efficiency of separation, complicated operation, difficult grasp, is difficult to be applied to big industrial production to making but still exist.
The purpose of this utility model provides and a kind ofly can make sorting material repeatedly polymerization, dispersion under low field intensity, magnetic mineral is effectively separated with intergrowth with gangue, magnetic is mingled with drops to bottom line, less energy consumption, the overflow grade is stable, and can be used for industrial continuous production magnet-gravity ore machine.
The utility model is to realize like this, the magnetic system that it is made of mineral-feeding pipe, overflow outlet, magnet exciting coil, separation tube, feed pipe, concentrate ore discharge pipe and central drawing device are formed, it is characterized in that the overflow outlet is the closing in structure of diameter less than separation tube, the magnet exciting coil that constitutes magnetic system is that odd number is arranged, feed pipe is two, is symmetricly set on the bottom of separation tube respectively.
Also first is the magnet exciting coil of controlled constant electromagnetic field to main points of the present utility model in the magnet exciting coil top of described odd number layout again.All the other are controlled pulse electromagnetic field magnet exciting coil.
The utility model has the advantages that, owing to adopted said structure and unique magnetic system, in ore separators, from top to bottom form and scan, roughly select and selected district, two feed pipes have been adopted in addition, make ascending current form the tangential water supply modes of couple type, the current turning effort strengthens, and makes non magnetic ore particle and intergrowth thereof fully disperse come-up, has the synergy of magnetic force, gravity and rising waterpower in every layer of magnetic system simultaneously.Make magnetic iron ore particle poly-chain, dispersion, sorting, sedimentation under constant and the effect of pulsation combination field, improved beneficiating efficiency effectively, and reduced energy consumption.
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is a structural representation of the present utility model.
Referring to accompanying drawing 1, it is made up of magnetic system, separation tube 5, feed pipe 7, concentrate ore discharge pipe 8 and CCU 13 that mineral-feeding pipe 1, overflow outlet 2, magnet exciting coil constitute, it is characterized in that overflow outlet 2 is the closing in structure of diameter less than separation tube, the magnet exciting coil that constitutes magnetic system is that odd number is arranged, first is the magnet exciting coil 4 of controlled constant electromagnetic field for the magnet exciting coil top that its odd number is arranged, all the other are controlled pulse electromagnetic field magnet exciting coil 6.For increasing the current spin intensity, feed pipe 7 of the present utility model is designed to two, is symmetricly set on the bottom of separation tube respectively.After the magnetic iron ore particle enters separation tube 5 by mineral-feeding pipe 1.Under the effect of magnetic force, form magnetic coagulation, move downward under the effect of gravity and pulsating field, non magnetic ore particle and intergrowth thereof tangentially feed under the effect of current at the couple type of feed pipe 7, fully disperse come-up, realized separating of magnetic mineral particle and gangue intergrowth.The fine magnetic mineral particle that partial monosomy dissociates, moving to stationary magnetic field magnetic under the ascending current effect is 4 o'clock, to be subjected to the effect of magnetic field force and form magnetic coagulation, enter separation tube 5 once more by sorting, thereby avoided the loss of fine magnetic mineral, gangue and intergrowth are then discharged by overflow launder 3 from overfall 2.Overfall 2 adopts is closing in structure less than the separation tube diameter, helps overflow like this and discharges fast, has reached water-saving purpose.
Main points of the present utility model also are, be provided with mine-supplying quantity control module 9 in the front portion of mineral-feeding pipe 1, be provided with ore discharge amount, grade, concentration Automatic Detection and Control unit 10 in ore discharge pipe 1 bottom, be provided with the water yield, hydraulic pressure automatic control unit 11 on feed pipe 7, above-mentioned three control modules together link to each other with CCU 13 with magnetic field control power supply 12.Above-mentioned these control device all adopt existing control system, this equipment can be realized adjusting automatically for ore deposit amount, running ore thickness, output, effluent concentration, concentrate grade like this, stable operation has reached the purpose of the whole ore dressing process of automatic control, satisfies need of industrial production.
