Description
Technical field
The invention belongs to a kind of gravity beneficiation equipments, and in particular to a kind of vertical centrifugal ore selector can be used for gold, silver, platinum
The ore-dressing practice of the non-ferrous metals such as the noble metals such as race and tungsten, tin, lead, zinc, particularly for the extensive of iron ore, serialization sorting
It is applicable in.
Background technology
Common water-jacket typ automatic centrifugation ore separators is the enhanced special gravity mine equipment based on centrifugal principle, is generally used for locating
It manages and recycles the noble metals such as gold, silver, platinum family and the metalliferous mineral of other greater densities from ore, be gold, noble metal association
The common gravitational separation equipment of non-ferrous metal ore factory.
Vertical centrifugal ore selector grading principle is：After importing interior rotating cylinder to mine ore pulp, heavy mineral Quick spin is deposited in
The lower half of rotating cylinder, the part in them are moved upward in final election slot, the back-flushing on barrel with centrifugation force effect
Under effect, mineral are able to loose and selected in slot.For light mineral because suffered centrifugal force is small, being flushed outside rotating cylinder becomes tailing.Weight
Because by larger centrifugal force, being retained in concentrate bed, concentrate discharging modes are divided into as interruption ore discharge and continuously may be used mineral grain
Become ore discharge.
Vertical centrifugal ore selector has many advantages, such as that small, light-weight, power consumption is small, easy care, concentration ratio are high, and does not need
Medicament adds, to realizing that Green Mine is of great importance.The sorting mode being combined using strong magnetic-centrifugal classification is to solve
The effective way of the refractory hematite utilization of resources.Vertical centrifugal ore selector can be effectively reduced the lower limit of gravity treatment granularity, promote
The recycling of Separate Fine-grained Minerals and the comprehensive utilization of tailing.
Currently, the mine-feeding equipment of vertical centrifugal ore selector is made of a mineral-feeding pipe and circular flat pallet, mineral-feeding pipe end
There is taper closing in, since the density variation of these mineral is larger, main sorting is tapered sleeve part, is selected using common vertical centrifugal
The charging gear of mine machine.
In the past more than ten years, the batch centrifugal ore separators designed and developed according to gravity separation principle gold at home
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 STL series Water sleeve centrifugal ore sortings, including R ＆ D of complex, product are set
It counts with verification, product improvement front-end geometry with application to when technological parameter, and person selects a kind of backwash continuous centrifugal
The structure and working method of mine machine are studied and have been designed, but are not applied successfully industrially up to now.
Along with the continuous reduction of rich ore and easy quarry, the grade of ore in part mine declines year by year, the embedding cloth grain of mineral
It spends superfine.Vertical centrifugal ore dressing is especially sorted in microfine iron ore concentrate by the research and attention of more ore dressing researchers
In terms of the recycling for bloodstone in iron tailings, some Science Explorations and Primary Study have been done.
Refractory hematite reserves account for about the 1/3 of national gross reserves in the explored iron ore deposit in China, and bloodstone
For density far below precious metal minerals such as gold, silver, the charging gear for commonly using vertical centrifugal ore selector is uneven there is cone material feeding is sorted
It is even, advance centrifugal classification can not be shifted to an earlier date, effectively disperse the problems such as ore pulp, cause the concentrate grade in hematite separation low, therefore,
Must the charging gear of vertical centrifugal ore separator be improved, preselect in advance as far as possible, to effectively solve hematite separation
The low defect of middle concentrate grade improves production and technical indication.
Invention content

It starches, be conducive to the uniform material feeding of sorting cone, the vertical centrifugal ore selector with advance sorting.
Above-mentioned purpose to realize the present invention, a kind of vertical centrifugal ore selector with advance sorting of the present invention use
Following technical scheme：
A kind of vertical centrifugal ore selector with advance sorting of the present invention is by charging gear, rotation sorting discharge cone
Cylinder, water jacket, main shaft, motor, engine base, automatic control system, water supply installation, concentrate slot, tailing slot, rack, V belt wheels, rotation connect
Head, outer barrel combination are constituted, and concentrate slot is communicated by pipe fitting with the inner wall of rotation sorting discharging cone cylinder, and tailing slot is sorted with rotation
The overflow port of discharging cone cylinder communicates, and rotation sorting discharging cone cylinder is connected and fixed with main shaft, and a pair of bearings and bearing are cased on main shaft
Seat, bearing block are fixed on the rack by flange；Water jacket is located in outer barrel and is sleeved on around rotation sorting discharging cone cylinder；Electricity
Machine drives main shaft and rotation sorting discharging cone cylinder to rotate together by V belt wheels；The inner wall of the rotation sorting discharging cone cylinder (2)
Angle of inclination with vertical direction is 12-18 degree, is preferred with 14-16 degree.In order to effectively disperse ore pulp, to the material fed
It is sorted in advance, the charging gear is made of relative combinations above and below layering swirl component, water diversion part：
The layering swirl component contains mineral-feeding pipe, and the lower mouth of mineral-feeding pipe is tapered closing in, and tapered closing in is conducive to
Even distribution ore pulp, and the material for controlling different densities rank feeds the initial velocity of the rotation sorting discharging cone cylinder of vertical centrifugal ore selector
Degree；The interior final election Circular Plate that 3-6 layers of diameter of parallel installation are gradually increased from bottom to top on mineral-feeding pipe, every layer of interior final election annulus
Between the outer rim of plate and the inner wall of the rotation sorting discharging cone cylinder of vertical centrifugal ore selector there are for ore pulp by gap.
The water diversion part contains lifts plate, convex by radial equidistant installation parabola around center in lifts plate
Block, the gap between adjoining parabolic line convex block constitute fan-shaped ore pulp flow-guiding channel.
The top of mineral-feeding pipe passes through and is welded on the centre bore of upper cover plate, and upper cover plate the cover is on outer barrel；Rotation connects
Head is mounted on the lower end of main shaft；Water supply installation contains there are two branch pipe, and one of branch pipe is inserted into rotation sorting from mineral-feeding pipe top
In discharging cone cylinder, another branch pipe is then connect from lower part by rotary joint with main shaft, and is reached by the hollow space of main shaft
In water jacket.
To prevent rotary body vibration aggravation, it is mounted with cushion blocking between rack and engine base, rotates sorting discharging to absorb
Vibration caused by cone cylinder rotation.
The interior final election Circular Plate is opposite with the inner wall sorting groove of rotation sorting discharging cone cylinder of vertical centrifugal ore selector,
To control ore pulp laminar flow；The parabola convex block is mounted on by fixing bolt in lifts plate and fixed seat, fixed seat
