Background technology
Suspension dry-type magnetic extractor is that the one kind grown up recently as the progress of mineral processing technology is used to improve tail
Ore deposit throws tail rate and reduces the dry ore dressing apparatus of mine tailing magnetic iron content, mainly for sorting for the magnetic ore after crushing.It is public
The suspension dry-type magnetic extractor known mainly selects belt feeder and campaigning belt feeder including main.It is main to select belt feeder mainly for coarse fraction ore
Sort, concentrate falls into concentrate case, and the small gangue of magnetic falls into tailing tank due to departing from magnetic system by the effect of gravity.Campaigning belt
Eedle sorts concentrate as magnetic drum falls into concentrate case below to fine fraction gangue, and the small gangue of magnetic is by Action of Gravity Field
Fall into tailing tank.The horizontal permanent magnetic system of this magnetic separator is disposed in the main of top and selected in belt feeder, and ore is with
The campaigning belt feeder feed of side.The larger magnetic iron ore of particle is attracted to be attached to the main skin for selecting belt feeder by horizontal permanent magnetic system
Take, the less magnetic iron ore of particle is attracted to be attached on the belt of campaigning belt feeder by campaigning belt feeder magnetic separation roller, this
Magnetic system in kind, under suspension dry-type magnetic extractor to ore deposit, compared with common permanent magnet dry type magnetic ore separator, solve and occur in sorting
Plus slag and fine fraction difficulty the problem of select, improve the yield of concentrate, reduce magnetic iron content in mine tailing.
But, because the most iron ore mines of China have the phenomenon that Magnetite Deposits and bloodstone bed are overlapping, intersect, adopting in addition
Fortune, bulk intergrowth is mixed into shattering process, causes the production scene to enter magnetic iron ore magnetic rate fluctuation before mill, in addition on
It is permanent magnetic system to state main and auxiliary two sets used in suspension dry-type magnetic extractor and sort magnetic system, and without adjustment space, accommodation is narrow,
When ore properties fluctuation is run into, it may appear that the phenomenon of " essence is without smart, useless without useless ", ore-dressing practice has been had a strong impact on
Effect, it would be highly desirable to improved.

The beneficial effects of the utility model are：
It is of the present utility model it is main select magnetic system and campaigning magnetic system to be electromagnetic system, can by power distribution cabinet adjust exciting curent it is big
It is small, so as to change the main magnetic field intensity for selecting magnetic system and campaigning magnetic system to adapt to the ore properties that scene changes at any time；It is main to select magnetic system
It is main to select magnetic system to have certain length above ore, more adsorbed chance can be created for magnetic ore；Magnetic mineral exists
Main select is in suspension loose condition (of surface) in the presence of magnetic system, it is to avoid come across being mingled with and wrapping up phenomenon for gangue mineral.This practicality is new
Type changes the magnetic system installation site of conventional magnetic ore deposit dry separation equipment, while having selected electromagnetic system, the sorting of ore can be made more thorough
Bottom, and can better adapt to different quality magnetic iron ores sort requirement, with significant economic benefit, being worthy to be popularized makes
With.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Marked in figure as follows：It is main select belt feeder 1, it is main select magnetic system 2, to ore deposit belt feeder 3, to barrow band great wheel 4, campaigning magnetic system
5th, cutting plate 6, main select belt great wheel 7.
Embodiment
The utility model by transmission device, charging gear, concentrate case, tailing tank, it is main select belt feeder 1, it is main select magnetic system 2, to
Ore deposit belt feeder 3, campaigning magnetic system 5, cutting plate 6 are constituted.
Transmission device of the present utility model selects belt feeder 1, is connected to ore deposit belt feeder 3 with main respectively, charging gear connection
In the feed end to ore deposit belt feeder 3, concentrate case and tailing tank select belt feeder 1 and the discharge end to ore deposit belt feeder 3 positioned at main respectively,
Main to select belt feeder 1 to be located at the top to ore deposit belt feeder 3, these structures are prior arts, are repeated no more.
Shown in figure, it is main to select magnetic system 2 to be arranged in the main frame selected in belt feeder 1, it is main to select magnetic system 2 to select belt feeder along main
The length direction of 1 frame is laid.Had the advantage that using this structure：It is first, main to select magnetic system 2 to be enclosed in stainless steel casing,
And be fixed in frame, be not in the phenomenon such as come off, shift；Secondly, main to select magnetic system above ore, magnetic mineral is in main choosing
Suspension loose condition (of surface) is in the presence of magnetic system 2, it is to avoid come across being mingled with and wrapping up phenomenon for gangue mineral；It is main to select magnetic system 2 to have
Certain length, can create more adsorbed chance for magnetic ore.
Shown in figure, campaigning magnetic system 5 is arranged on to inside barrow band head pulley 4, and campaigning magnetic system 5 is along giving ore deposit belt conveyer head
4 front end circular arcs are taken turns to lay, it is main to select belt feeder 1 to be longer than in heading to ore deposit belt feeder 3.
Shown in figure, it is main to select magnetic system 2 and campaigning magnetic system 5 to be electromagnetism magnetic system, it is main select magnetic system 2 magnetic field intensity requirement 0 ~
1500mT, the magnetic field intensity of campaigning magnetic system 5 requires 0 ~ 1000mT.It is main to select magnetic system 2 and campaigning magnetic system 5 to be adjusted by power distribution cabinet
Exciting curent size, so as to change the main magnetic field intensity for selecting magnetic system 2 and campaigning magnetic system 5 to adapt to the ore that scene changes at any time
Matter.
In figure show, cutting plate 6 is provided with below belt feeder 1 in main select, cutting plate 6 be located at it is main select belt feeder great wheel 7 with
To between barrow band head pulley 4, concentrate case and tailing tank are respectively positioned at the rear and front end of cutting plate 6.
The course of work of the present utility model is as follows：
Raw ore after broken passed through to ore deposit belt-conveying to sorting region, it is main select above belt feeder 1 main select the energization of magnetic system 2
After produce electromagnetic field（Magnetic field intensity is adjustable in 0 ~ 1500mT）, material it is main select the upward magnetic force of magnetic system 2, material gravity itself and
Under the synergy of belt belt speed, the strong magnetic mineral of magnetic is in suspension loose condition (of surface), is then adsorbed to and main selects belt following table
On face, and belt is selected to bring into concentrate collecting box by main；The weaker magnetic mineral of remaining magnetic and gangue mineral pass through to ore deposit
The campaigning magnetic system 5 of belt great wheel 4（Magnetic field intensity is adjustable in 0 ~ 1000mT after campaigning magnetic system is powered）After scanning, weak magnetic mineral with
Gangue mineral is separated, and gangue mineral is directly entered tailing tank as mine tailing, and weak magnetic mineral enters concentrate collecting box.Entirely dividing
During choosing, can be adjusted according to ore properties the main magnetic field intensity for selecting magnetic system 2 and campaigning magnetic system 5 and the regulation position of cutting plate 6 come
Control concentrate, the yield of mine tailing.
In addition, in actual production process, it is contemplated that the bed of material on feeding belt has certain thickness, positioned at material lower floor
