Description
Technical field
The invention belongs to a kind of gravity beneficiation equipment, and in particular to a kind of vertical centrifugal ore selector, and water-jacket typ is replaced with it
Automatic centrifugation ore separators, can be achieved the continuous ore discharge of vertical centrifugal ore selector, be particularly suitable for use in the efficient of bloodstone in iron tailings
Reclaim.
Background technology
Vertical centrifugal ore selector is the general designation of rotary shaft right angle setting centrifugal ore separator, and operation principle is the driving in motor
Under, cone cylinder is rotated by V belt wheel transmissions, drives the ore pulp in cone cylinder to rotate at a high speed, in the process, based on different densities
The difference of the suffered centrifugal force of grain, different densities particle realizes separation under centrifugal sedimentation and stream film turbulent diffusion.
Vertical centrifugal ore selector, including external Knelson (Nelson) centrifugal ore separators and Falcon (Fa Erkang) from
Heart ore separators and domestic Water sleeve centrifugal ore sorting, for the enrichment of the mineral such as chromite, ilmenite, Iron Oxide Minerals, tool
There is ratio of concentration height, treating capacity is big, floor space is small, assorting room is quick effectively, device structure is simple, production cost is low, to ring
The advantages of border is friendly.And do not limited by grain graininess, greatly reduce the granularity lower limit of recyclable mineral so that submicron-sized particulate
Gravity separation be possibly realized, in addition, it is not necessary that medicament is added, because the discharge of mine tailing and the purification of waste are simplified, not only
Production cost is reduced, and reduces Environmental costs.Vertical centrifugal ore selector is increasingly by the weight of ore dressing researcher
Depending on.
But it is architectural limitation to be applied to industrial most of vertical centrifugal ore selectors at present, can only be interrupted discharge essence
Ore deposit, it is impossible to work continuously, therefore it is basically applied to the noble metals such as the few gold, silver of concentrate quantum of output, platinum family and tungsten, tin, lead, zinc
Deng the ore-dressing practice of non-ferrous metal.
In the past more than ten years, the batch centrifugal ore separators gold at home developed according to gravity separation principle design
Mine is widely applied.《Gold》" the STL series Water sleeve centrifugal ore sorting R ＆ D designs that 7th periodical in 2016 is delivered
And application " in a text, introduce the current situation of the serial Water sleeve centrifugal ore sortings of STL, including R ＆ D of complex, product are set
Meter is with verifying, product improvement front-end geometry is selected with application to when technological parameter, and to one kind backwash continuous centrifugal
The structure and working method of ore deposit machine are studied and designed, but are not applied successfully industrially up to now.
The content of the invention
The purpose of the present invention has automatic discharging work(aiming above shortcomings in the prior art there is provided one kind
Can, it can work continuously, and the vertical centrifugal for being capable of continuous ore discharge for the Hematite separation that production capacity is big, power consumption is small
Ore separators.
To realize the above-mentioned purpose of the present invention, a kind of vertical centrifugal for being capable of continuous ore discharge of Hematite separation of the invention
Ore separators uses following technical scheme：
A kind of vertical centrifugal ore selector for being capable of continuous ore discharge of Hematite separation of the present invention, by charging gear, is sorted
Discharging cone cylinder, water jacket, main shaft, motor, support, control sorting discharging cone cylinder operating and water supply installation water size are automatically controlled
System, water supply installation, concentrate hopper, tail-box, frame, V belt wheels, outer cylinder body, cover plate, device for discharging combination are constituted, and described gives
Material device contains mineral-feeding pipe, and tail-box is communicated with sorting the overfall of discharging cone cylinder, and sorting discharging cone cylinder is connected with main shaft,
A pair of bearings and bearing block are cased with main shaft, bearing block is fixed in frame by flange；Water jacket is located in outer cylinder body and is enclosed on
Sort around discharging cone cylinder；Motor drives main shaft and sorting discharging cone cylinder to rotate together by V belt wheels, drives the ore deposit in cone cylinder
Slurry rotates at a high speed, takes full advantage of centrifugal inertial force, gravity, buoyancy, gravity flow effect, can be achieved to work continuously；Mineral-feeding pipe it is upper
Portion is passed through and is welded on the centre bore of cover plate, and plate cover is covered on outer cylinder body, and the lower mouth of mineral-feeding pipe closes up to be tapered.Its feature
It is：
Swivel joint is housed in the lower end of main shaft, water supply installation contains two branch pipes, one of branch pipe is from cover plate top
In insertion sorting discharging cone cylinder, another branch pipe is then connected from bottom by swivel joint with main shaft, and passes through the hollow of main shaft
Part is reached in water jacket；
Described sorting discharging cone cylinder is to be interlocked to be superimposed the round table-like knot for constituting upper big, lower small by cylinder piece and circular ring plate
It is groove at structure, the inwall of each round table-like structure；
Described device for discharging includes：Be welded on the inverted trapezoidal blade of mineral-feeding pipe end, 2-5 wedge scraper, flat pallet,
Concentrate ore discharge pipe, shutdown ore discharge pipe；2-5 wedge scraper is stratified and set near the groove in sorting discharging cone cylinder, and is passed through
Cross hanger is lifted on mineral-feeding pipe；Flat pallet is located in sorting discharging cone cylinder, and relative with the tapered closing in of mouth under mineral-feeding pipe；
The lower end of concentrate ore discharge pipe connects with concentrate hopper, and concentrate ore discharge pipe top is each passed through after water jacket, sorting discharging cone cylinder and sorting
Groove at discharging cone cylinder inwall is communicated, to discharge the high density concentrate in groove；Being additionally provided with concentrate ore discharge pipe is used for
Adjust the pinch valve of concentrate yield and concentrate grade；Shut down ore discharge pipe and be connected with sorting the bottom of discharging cone cylinder, unloaded in sorting
Material cone cylinder not ore discharge when running at high speed, the ore pulp of sorting discharging cone cylinder can be quickly discharged when shutting down, in order to avoid block.The present invention
The inverted trapezoidal blade of installation is effectively facilitated under the groove binding of sorting discharging cone cylinder, and ore pulp presses radial and axial layered-rotation,
Sort discharging cone cylinder in material particles under the action of the centrifugal force, it is for the helical movement, if there is no inverted trapezoidal blade, part mineral by
In close to sorting discharging cone cylinder center, the newel for being difficult to sort can be formed under " short circuit " situation by sorting discharging cone cylinder
Region, and the present invention devises inverted trapezoidal blade, have compressed core, reduces unsorted particle and runs through sorting discharging
The possibility of cone cylinder, makes all ore pulps for the helical movement with sorting discharging cone cylinder.In addition, inverted trapezoidal blade prevents ore pulp fast
