The discharging road junction 3 in road 2 and dust-extraction unit 4 are tightly connected.After Emanator device 5 dishes out mineral grain, mineral grain is in sky
In do the centrifugal movement of horizontal direction, produced in the level throw motion of vertical direction, and by the fine ore dressing host blower of differentiation
Raw wind-force.When moving in the sky, the bigger mineral grain run duration of quality is longer, and the displacement of horizontal direction is remoter,
More outer Ring-cylindrical channel 2 will be fallen on when dropping into stock grading sleeve, therefore can be big according to quality by mineral grain
It is small to be divided into different brackets, and there is density contrast between mineral grain and waste material, into the mineral grain in the same Ring-cylindrical channel 2
Easily mineral grain can be screened by volume difference.Thin slice for fixing concentric sleeve 1 is cut with concentric sleeve 1
Face is stopped when can vertically prevent mineral grain from falling.Drop into the mineral grain quality in the Ring-cylindrical channel 2 of innermost layer
Most light, most of is waste material, is likely to result in dust pollution, and most of dust can be removed after dust-extraction unit 4 by connecting, and other
The mineral grain in Ring-cylindrical channel 2 does not have too tiny dust.
Further technical solution is, the diameter of innermost layer sleeve 11 is equal to the straight of receiver 51 in Emanator device 5
Diameter, receiver 51 be it is discoid, be the rotary part on Emanator device 5, exhaled for mineral grain therein will to be fallen into
Come.It can prevent mineral grain from dropping into inside innermost layer sleeve 11 in this way, general other schemes are easy to drop into innermost layer set
Mineral grain inside cylinder 11 is 600 mesh and more tiny mineral grain, can be fallen directly into the present case most
In the Ring-cylindrical channel 2 that inner layer sleeve 11 is formed with outer one layer concentric sleeve 1.
Further technical solution is to be equipped on the outside of all middle layer sleeves 12 in concentric sleeve 1 to overhanging
The splicing plate 6 of exhibition, splicing plate 6 are the road junction 3 that discharges with the outlet that outer one layer concentric sleeve contact position is opened.Enter in mineral grain
Stock grading sleeve and after being divided into multiple grades, continues on the movement of Ring-cylindrical channel 2, in each Ring-cylindrical channel 2 is
Cavity between outer two concentric sleeves 1, mineral grain move on the splicing plate 6 installed on the concentric sleeve 1 of internal layer, then exist
Stock grading sleeve is left at the discharging road junction 3 that splicing plate 6 is opened with outer one layer concentric 1 contact position of sleeve, completes point of mineral grain
Grade.Collection device can be set under the road junction 3 that discharges to be collected.One or more can be set on each sleeve 1 with one heart to connect
Multiple discharge ports 31 can also be arranged simultaneously while being discharged to improve treatment effeciency for flitch 6.Wherein splicing plate 6 and discharging
Road junction 3 can be 1,2,3,4,5,6, including but not limited to the example above, preferably 2~3.
Further technical solution is that splicing plate 6 is ridge-shaped, is made of two pieces of inclined plates 61, the setting of 61 edge of inclined plate
There is vertical rib 62, angle is 90~120 ° between two pieces of inclined plates 61, and 61 lowest part of inclined plate is provided with discharge port 31.Wherein connect
The ridge side of flitch 6 is the intersection of two inclined plates 61, and ridge side passes through the center of circle in concentric 1 section of sleeve, and such mineral grain is fallen
When can be divided to by two inclined plates 61 for two parts, and discharge from two discharge ports 31.61 edge of inclined plate is provided with vertical gear
Side 62 can prevent mineral grain from falling when moving on splicing plate 6.Between two inclined plates 61 angle be can be 90,91,92,
93、94、95、96、97、98、99、100、101、102、103、104、105、106、107、108、109、110、111、112、113、
114,115,116,117,118,119,120 °, including but not limited to the example above, the angle between splicing plate 6 is in this range
Can be moved downward along splicing plate 6 when mineral grain is fallen on splicing plate 6 when interior, without because reaction force is too big and bullet
It rises and falls on except splicing plate 6.
Further technical solution is that the diameter difference of two adjacent from inside to outside concentric sleeves 1 of concentric sleeve 1 is gradually
Increase.The diameter difference of two adjacent from inside to outside concentric sleeves 1 of concentric sleeve 1 is gradually increased, obtaining the result is that Ring-cylindrical
The width in channel 2 gradually increases.When in use, the mineral grain dished out by Emanator device 5 is by wind vertically downward
Gradually it is divided into different grades after power according to quality, wherein the smaller horizontal displacement of quality is smaller just closer to innermost layer sleeve
11, and when the small particle of quality falls on concentric 1 top edge of sleeve, between relative position it is also closer, therefore the particle that quality is small
It can be distributed in when falling on concentric 1 top edge of sleeve in the lesser annulus of width；When mineral grain quality is gradually increased, ad eundem
Mineral grain between relative position it is remoter, therefore while falling on concentric 1 top edge of sleeve be distributed in far from innermost layer sleeve 11 and
In the biggish annulus of width.So the diameter difference needs of two adjacent from inside to outside concentric sleeves 1 of sleeve 1 are gradually increased with one heart
The mineral grain of each grade can be classified, be not in the biggish same grade mineral grain of quality be divided into it is more
The case where a grade, can save the cost, improve working efficiency.
Further technical solution is that stock grading sleeve includes 3~21 concentric sleeves 1.Wherein adjacent two
The Ring-cylindrical channel 2 constituted between concentric sleeve 1 can pass through for mineral grain, and 3~21 concentric sleeves 1 can form 2~
20 Ring-cylindrical channels 2 are divided into 2~20 grades to mineral grain, are far longer than at present generally to the classification number of mineral grain
Amount.Wherein stock grading sleeve may include 3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21
A concentric sleeve 1, preferably 5~16, including but not limited to the example above, can be according to practical mineral and classification demand
It is adjusted.It is more careful to be classified to mineral grain, is separated in progress mineral and waste material more efficient.Such as in a kind of embodiment party
In formula, 200 mesh mineral grain below is classified between every 50 mesh and is divided into a rank, wherein being divided into a rank between every 50 mesh
Refer to the mesh number of the mesh number of valuable mineral particle in each rank rather than gangue or waste material.It is divided into 9 ranks, is respectively as follows: 200-
250,250-300,300-350,350-400,400-450,450-500,500-550,550-600, below 600 mesh.Same
Gangue or waste material volume in a rank is bigger compared to ore, could obtain momentum identical with ore in this way to be divided into
The same grade, thus be classified after can by volume differences easily by ore be screened out from it come.
Further technical solution is that anti-wind net 63 is equipped on splicing plate 6；Anti-wind net 63 is parallel with inclined plate 61, and
It is provided with gap between the two.Wherein the mesh number of anti-wind net 63 is 14~50 mesh, and the anti-wind net 63 of this specification can make mineral
Grain drops into the gap between 63 lower section of anti-wind net and inclined plate 61, effectively mineral grain is prevented to be blown up.Mine when in use
Composition granule is dropped on the anti-wind net 63 on splicing plate 6 by a Ring-cylindrical channel 2 of classification sleeve, after passing through anti-wind net 63
It falls on splicing plate 6, is slided into tiltedly after the gap small distance rebound several times between inclined plate 61 and anti-wind net 63 along inclined plate 61
The discharge port 31 of plate 61.While mineral grain is by classification sleeve, the air stream generated by blower also can be together through excessive
One Ring-cylindrical channel 2 of grade sleeve passes through anti-wind net 63 then as mineral grain, then anti-by the rebound blowout of splicing plate 6
Wind net 63.Mineral grain can be effectively reduced after installation anti-wind net 63 in actual production to be blown and bullet by the wind that blower generates
The probability of splicing plate 6 out.Stock grading sleeve not only has grading but also is also airflow channel, shape between concentric sleeve 1
The rectifying disc installed on the cyclic cooperation of cylindrical passageway 2 classification host remains steady smoothness by air-flow.
Further technical solution is that the top edge of several concentric sleeves 1 is located in same hierarchical planes 7, and classification is flat
Face 7 is parallel with receiver 51.Hierarchical planes 7 are parallel with receiver 51 can to guarantee that mineral grain is moved to from Emanator device 5
The vertical distance in each Ring-cylindrical channel 2 is identical.
Further technical solution is, hierarchical planes 7 be lower than with receiver 51, distance between the two is 6~12cm.
The movement in the sky and different brackets mineral grain in the sky that the spacing of hierarchical planes 7 and receiver 51 limits mineral grain
The scattered time, when the spacing of hierarchical planes 7 and receiver 51 is 6~12cm, mineral grain is when reaching hierarchical planes 7
Adequately scatter according to quality size, into stock grading sleeve after can reach preferable grading effect.If point
Grade plane 7 and the spacing of receiver 51 are too small, and the mineral grain of each grade is not dispersed throughout out also；If hierarchical planes 7 with connect
The spacing of charging tray 51 is too big, then the volume of equipment can be excessive, not economical enough.Wherein hierarchical planes 7 and the spacing of receiver 51 can
Think 6,7,8,9,10,11,12cm, preferably 8~10cm, including but not limited to the example above.Wherein hierarchical planes 7 with connect
The spacing of charging tray 51 can be adjusted, and be adjusted according to different mineral.
Further technical solution is that the section of concentric sleeve 1 is parallel with receiver 51, when two adjacent concentric locking collars
After the diameter difference of cylinder 1 is more than or equal to 80mm, relatively interior one layer of 1 diameter difference of concentric sleeve of the concentric sleeve 1 of more outer layer no longer increases, Gu
It is set to 80mm, and the position where 1 top edge of sleeve gradually rises with one heart.When the diameter difference of two adjacent concentric sleeves 1 is big
The diameter difference for continuing to increase the concentric sleeve 1 of adjacent two after being equal to 80mm can be such that host volume also increases together.To be outer
The concentric sleeve 1 of layer relatively in one layer of 1 diameter difference of concentric sleeve be fixed as 80mm, then by the position where these concentric sleeve top edges
It sets and gradually rises.The farther same grade mineral grain of horizontal displacement can thus bumped against on the barrel of concentric drums, into
And in advance into completion classification in the Ring-cylindrical channel 2 of the grade, the diameter of concentric drums can be thus reduced, equipment is reduced
Cost.It is wherein when the width in Ring-cylindrical channel 2 is less than 40mm when the diameter difference of two adjacent concentric sleeves 1 is less than 80mm
Concentric sleeve 1 can not be improved, needs to improve concentric sleeve 1 highly when the width in Ring-cylindrical channel 2 is greater than 40mm to reduce
The width in Ring-cylindrical channel 2.The concentric highest position in 1 top edge of sleeve is no more than the receiver 51 of Emanator device 5.It is wherein same
It is that principle is calculated that the raised size of heart sleeve 1, which will not be repelled go back to upper level Ring-cylindrical channel 2 with mineral grain,.In this way
Not only grading effect can not be influenced but also contour size of the unit(s) can be reduced, also saving manufacturing cost.It is rebounded by the wall of concentric sleeve 1
Mineral grain back nevertheless suffers from the downward wind-force effect of blower generation, while there are also enter mineral grain afterwards to collide.To
Under the active force of wind-force can also allow the direction of motion of mineral grain to change.Because mineral grain quality size is different, phase
The height that the faster therefore more inner concentric sleeve 1 of the smaller motion change of quality needs to be promoted under same initial velocity is smaller.Work as object
It, can wind-force, Emanator device 5 by adjusting blower to change the mineral of classification after the size of material classification sleeve is fixed
Receiver 51 revolving speed and receiver 51 enable mineral grain is good to be classified at a distance from hierarchical planes 7.
The principle of the present invention illustrates: stock grading sleeve of the invention is mounted on the fine ore dressing host of differentiation, difference
Changing fine ore dressing host includes: cylindrical host sleeve；Section with host sleeve is installed in cylinder host sleeve inner upper
The parallel blower in face；Host sleeve inner is also equipped with several rectifying discs parallel with blower；It passes through and send in the middle part of rectifying disc
Pipe material, the feed end of charging line are arranged in the lower section of blower and are pierced by from the side of host sleeve；It is set below charging line
Emanator device 5 is set, Emanator device 5 includes the platen installed on receiver 51 and receiver 51, receiver 51 and platen
Between have cavity, be provided with gap between receiver 51 and the contact surface of platen；In 5 lower part of the Emanator device setting present invention
Stock grading sleeve；Stock grading sleeve is made of multiple concentric sleeves 1 concentric with receiver 51.In a kind of embodiment
A diameter anti-air hose identical with platen can also be arranged in the position that middle rectification disk center passes through charging line, prevent blower from producing
Raw wind is directly blown on pressing plate and wind vertically downward is caused to become disorder.
When in use, charging line is entered by the honed mineral powder of ball mill, then along vertical feeding main pipe
Road is downward, leaves the conical sleeve that charging line enters on 5 platen of Emanator device, passes through entering by platen after conical sleeve
Material mouth enters the cavity between platen and receiver 51.Emanator device 5 passes through the motor installed below and is rotated, and rotates
The centrifugal force of generation forces the mineral grain in platen and 51 cavity of receiver to move to cavity surrounding, and mineral grain is along annulus
The inclined-plane of inner ring is upward, moves to the intersection of platen Yu receiver 51, and fill from emanator by the gap of intersection
It sets 5 throwings to dissipate and go out, throws and dissipate horizontally 360 degree of direction, no matter granular size can guarantee ore particle with identical initial velocity
It is gone out by dispersion, the gap size of Emanator device 5 can adjust in the range of 0.1~1.5mm, and mineral grain processed is big
It is small to determine gap aperture.Dispersed what the mineral grain of Emanator device 5 out was generated by gravity, air drag and blower
Acted on while downdraught, the mineral of different quality size after by force action move distance it is completely different, quality it is big away from
It is small from particle is distal to, thereby realize classification overall process.In addition because close between the equirotal mineral of quality and gangue
Difference is spent, it is different for leading to volume, because being respectively less than using the mineral grain that the fine ore dressing host of differentiation is classified
200 mesh, therefore the air drag being subject to thinks identical, mineral and gangue identical in quality size and that volume is different can be assigned to
In the same grade, then can be easily separated therefore also complete between the substance of different densities difference by it by volume difference
At graded operation.This makes it possible to allow big density variation substance between spread the work and become simple possible, traditional ore dressing
Complex process, difficulty is big, high pollution, high energy consumption, high-cost hard case will easily crack.
The movement of mineral grain after leaving Emanator device 5 is centrifugal movement in the horizontal plane, is on the vertical plane flat
Throw movement.And the wind-force that blower generates forms wind-force vertically downward after through rectifying disc.Wind-force vertically downward acts on
Reduce the run duration of mineral grain vertical direction after on mineral grain, run duration reduce after horizontal direction displacement also with
Reduction.The displacement of its bigger horizontal direction of the momentum of mineral grain is bigger, when falling into stock grading sleeve closer to outer
Side.The smallest waste material of quality drops into stock grading sleeve penetralia sleeve, then enters cleaner by discharging road junction 3.
Other mineral grains enter the different Ring-cylindrical channel 2 of stock grading sleeve, are divided into several grades, and go out from different
Material mouth 31 is collected.And because density variation causes quality different between the same mineral and gangue of granule size, it is identical
Resistance when the bigger move distance of quality it is farther, therefore graded operation has also been carried out between the substance of different densities difference.?
In each rank, mineral grain size is approximately equal, and gangue particle size is approximately equal, but mineral grain and gangue particle
Size be it is different, the big material grains of density be less than density it is small, it is as a result directly proportional to density ratio.When mineral grain with
The density ratio of gangue particle uses mechanical grading that can realize that high efficiency is screened after being greater than 1.3.Therefore differentiation is finely divided
It includes but is not limited to above mineral for having big density variation that grade equipment, which can allow copper mine, tin ore, tungsten ore, Pb-Zn deposits, and realization is adopted
It is sorted with simple, pollution-free, Ultra Low Cost, the grade and metal recovery rate of screening are higher than traditional ore-dressing technique.
The height of screening efficiency is to having sorted tremendous influence, such as the technology upgrading of mine of Taiyuan Iron and Steel Co. point mountain, screening efficiency
It is promoted from 35% to 75%, realizes that system production capacity promotes 5%, annual benefit more than 1,000 ten thousand.Efficient sieve classification can
The mineral of ore grinding qualification are separated in time, overground phenomenon is avoided to occur, reduce energy consumption, promotes production capacity, guarantee fund
Belong to the rate of recovery.Therefore the present invention also has good economic benefit.
Above-mentioned technical proposal of the invention has following beneficial technical effect: the mine that Emanator device 5 can be dished out
Composition granule point provides multiple classification channels, realizes fining sub-material.Mineral grain after grinding is divided into multiple grades, after convenient
Continuous ore dressing.Dust pollution is small, will not waste water resource.Good economic benefit can be generated.
