Description
Technical field
The invention belongs to magnetic separation technique field, and in particular to a kind of micro-fluidic refiner of magnetic and its complete magnetic separation are set
Standby, it belongs to novel intelligent electromagnetism separation equipment.
Background technology
With the iron ore tendency that the surplus and nearly a period of time in iron ore market even remain inactive over long periods of time, come for major ore dressing plants
Say, improve ore-dressing technique, reduce the production cost of Iron concentrate as urgent problem to be solved.
It can be realized at present by exploiting high-grade raw ore or improving ore-dressing technique for reduction powdered iron producing cost.
Due to the universal lean ore in domestic mine, rich ore is few, this approach of exploitation high-grade raw ore for the domestic overwhelming majority selects factory
It is almost irrealizable, so the production cost of Iron concentrate can only be reduced by lifting ore-dressing technique；And ore-dressing technique
It can be improved by the approach such as " much broken and lessmill " or " grinding multiselect less ", reach the purpose of reduction production cost.
For conventional wet type drum magnetic separator, it is sorted mainly by magnetic force, for concentrate it is selected again for, magnetic
Field intensity is high-leveled and difficult with guarantee high-grade and the high concentrate rate of recovery simultaneously；It is final to have to give up grade for the high concentrate rate of recovery of guarantee
Lifting amplitude.For sloughing-off tank, desliming is sorted using permanent magnet and water jointly, can only ensure to slough mud, it is impossible to folder is removed
Miscellaneous lean intergrowth, so grade lifting is limited.Column magnetic separator can ensure that height carries product amplitude and high-recovery simultaneously, but have processing
The low shortcoming of amount, it is difficult to realize maximization and high throughput.Although the products such as elutriation magnetic separator, grade elevator, borded pile are all
For overcoming disadvantage mentioned above, but water consumption is big；And because these equipment automatization levels are very low, it is necessary to which substantial amounts of manpower is gone
Regulation is safeguarded, therefore increases the cost of Iron concentrate.
Simultaneously for such magnetic gravitational separation equipment, it is necessary to can be only achieved height by feedwater and the very trickle fine cooperation in magnetic field
Separation index.High-recovery can be taken into account again while GOOD TASTE is pursued, and high-grade concentrate and minimum are obtained to the full extent
The race tail of amount.And the equipment water supply system such as elutriation magnetic separator, grade elevator, borded pile is simple at present, it is difficult to reach feedwater and
The fine fit in magnetic field；Which results in can not obtain optimal concentrate.Simultaneously as water supply system is extensive and causes equipment
Water consumption is huge.
In summary, in order to realize lifting ore-dressing technique, the production cost of Iron concentrate is reduced, more preferable concentrate is pursued
Grade and the rate of recovery.It is badly in need of the high large-scale product of a kind of grade lifting amplitude height, rate of recovery height, water consumption very little, automaticity
Position lifting means takes on the responsibility ground multiselect in ore-dressing technique less and reach preferable sorting target.

The present invention feeds ore pulp by feed launder 1 middle and upper part of sorting main frame 4.Magnetic-particle in ore pulp is made in magnetic field
Magnetic linkage is agglomerated under.Non-magnetic impurity is not agglomerated into magnetic linkage then, and reversely breaks up magnetic field handle by what is moved from bottom to top
Magnetic linkage is broken up, while the impurity being mixed in magnetic linkage is discharged, and formation free from admixture is mingled with the presence of resultant field
Magnetic linkage.Non-magnetic impurity enters mine tailing with ascending current in sorting main frame 4 after being discharged by magnetic linkage and discharged.
The magnetic size of magnetic-particle is directly proportional to the grade height of magnetic-particle.Magnetic linkage is big under same magnetic field intensity
It is small to be directly proportional to the magnetic of magnetic-particle.Therefore under same magnetic field intensity, the magnetic-particle grade that magnetic linkage size contains with it
It is directly proportional.The magnetic linkage group being made up of the magnetic linkage of different magnetic sizes forms magnetic linkage stream and continues to move downward.During moving downward
Magnetic linkage group is continued by the alternating action for reversely breaing up magnetic field and resultant field moved from bottom to top produced by magnetic system, magnetic linkage
Scatter and meet again.By the effect of resultant field, high-grade particle and high-grade particle agglomeration can all be made each time by meeting again,
Low-grade particle agglomeration is into small magnetic linkage.It is also the process that high-grade magnetic linkage is upgrade in the lower motion process of magnetic linkage flow direction.Simultaneously
In the process, the water of not same-action is fed inside sorting main frame 4 by each supply line.Adjusted in the intelligence of switch board 24
Under control, the difference such as overflow launder feed pipe 1, overflow launder feed pipe 2 15, upper feed pipe 13, middle feed pipe 18, lower feed pipe 11
The Multifunctional water-feed pipeline of position is worked in coordination, and the local fine bourn coordinated with magnetic field is formed in magnetic linkage stream.It is every in magnetic linkage stream
A low-grade magnetic linkage is formed, i.e., is weeded out by local fine bourn from magnetic linkage stream.Motion upwards after low-grade magnetic linkage is removed
Form mine tailing discharge.The magnetic linkage stream moved downward is purified by the mating reaction of this magnetic field and fine bourn.Finally
The high-grade magnetic linkage stream of formation flows downward to sorting main frame 4 bottom and forms concentrate discharge.
Because magnetic field and current are controlled by switch board 24, different magnetic field and the mated condition of current can be formed not
With the magnetic linkage stream and the low-grade magnetic linkage of different grades of grade.The two separation is finally realized into accurate sorting to ore pulp, protected
Most high-grade concentrate is obtained on the premise of demonstrate,proving the qualified rate of recovery.
Simultaneously as overflow launder feed pipe 1, overflow launder feed pipe 2 15, upper feed pipe 13, middle feed pipe 18, giving down
The Multifunctional water-feed pipeline of the grade diverse location of water pipe 11 and the setting of magnetic system and intelligence control system, make confluent more accurate,
Supply water on demand.And the micro-fluidic refiner inside magnetic linkage stream of auto-control magnetic, local fine bourn and the fine fit in magnetic field.Solve
The problem of water consumption is big, automaticity is low.
The foregoing is only a preferred embodiment of the present invention, but protection scope of the present invention be not limited thereto,
Any one skilled in the art the invention discloses technical scope in, the change or replacement that can be readily occurred in,
It should all be included within the scope of the present invention.Those skilled in the art is appreciated that without departing substantially from appended right
It is required that in the case of the spirit and scope of the present invention of definition, various modifications can be made in form and details.
