Description
Technical field
The present invention relates to the fields of separation raw mineral materials, and can be used for producing mobile separation equipment, the equipment according to
The processing of its element and classification raw material can be used under any weather condition, including under -50 to+50 DEG C of temperature.
Background technique
It is well known that the main method of separation ore, coal, nonmetallic materials first is that specific Density Separation method (i.e.
Gravity methods).The decline of extracted material quality and the essence of further processing is provided for power engineering, metallurgy and chemical business
The increase of mine quality requirement substantially increases the requirement to used raw material separation method efficiency.
Similarly, it is known that during the operation of separation equipment and metallurgical processing installation, it is useless to have had accumulated a large amount of mineral
Object.These wastes not only pollute environment, but also occupy the tract near settlement, cities and towns and other residential quarters.Greatly
In most cases, these mineral wastes are the important source materials of secondary operation.Thus, for example, the by-product from ferrochrome production contains
There is 2 to 12% metal ferrochrome；However, the content of the Chromium in Ores used in fusion process is 1% to 5%, this chromium is
Chemical bonding.Therefore, the secondary operation of by-product can not only improve the environmental condition of each region, and economically may be used
Row；However, the technology for processing specific waste has to comply with several strict demands.
Firstly, raw material isolation technics must be it is general, can easily be accommodated, for processing various raw mineral materials；Meanwhile it must
The material (for example, coal, ore, production waste and nonmetallic raw material) that partition density must be suitble to different.Processing program must provide
A kind of possibility quickly, easily changes processing method according to the property of raw material to be processed, requirement of converted products quality etc.,
This Capital expenditure that Modular moving formula separation equipment will be made to be used to transmit with device has lower level.
Secondly, raw material isolation technics must efficiently, provide the product obtained of high quality, and at it using it
Remaining by-product is unsuitable for further processing or industrial application afterwards.
Third, raw material isolation technics must be round-the-clock and annual, therefore the process is not labour relevant to season
Power resource temporarily participates in, but continual with the annual employment of local population.The work of raw material separation due to the above reasons,
The skill period must include -50 to+50 DEG C of ambient air temperature range, and equipment must be allowed for make in outdoor or small-sized builder's temporary shed
With.
Known raw material separation method widely used so far；It based on passing through the product of density in liquid medium
Separation is (referring to Razumov K.A.Perov V.A. " Designing of separation plants ", M., Nedra
1982, the 195-205 pages, the 268-282 pages).In the case where sizable practicability and cheap water resource, this method permits
The raw material separation process for being used for abundant yield is provided perhaps.
The major defect of known raw material separation method is that the application under the winter conditions under open-air condition is impossible
's.A large amount of material and financial resource is needed to ensure to heat in fact, building the professional factory runed based on whole year.?
Under winter conditions, even if in medium latitude, in the case where winter temperature moderate (peak value of negative temperature is between -5 to -10 DEG C),
Also it is difficult to use the known method and obtains competitive product.
There are also raw material separation methods known to another kind, are widely used recently.It is based on by air dielectric
Specific density product separation (referring to M.V.Verkhoturov " Gravitational separating methods " M.,
Max-Press 2006, the 306-318 pages), (G.N.Shokhin A.G.Lopatin " Gravitational separating
Methods ", M., Nedra 1993., page 9), including: isolated raw material is provided in gravity sedimentation chamber.The chamber
Room moves back and forth, the sieve that it enters equipped with air-flow from bottom.In the motion process along sieve, heavy substance is downward
It is mobile, and light material is moved to the top of the layer formed by the product for needing to be further processed.
This method allows the separation of whole year production raw material in the case where outdoor or use small-sized builder's temporary shed.
The major defect of the raw material separation method is the low efficiency of product separation process, the light material in heavy product
Height exist, the process can all carry out in the gas producing formation being placed on sieve.Increasing thickness is to generate different densities product
The necessary condition of separate layer leads to its high resistance, low so as to cause its removal degree, feed separation low efficiency.For difference
The Raw material processing of type, it is ensured that being quickly converted for manufacturing process is impossible, as long as producing each separator, all only
Can in preset density range converted products.
Further, since the high humility effect of raw material, the ad hoc approach for raw material separation do not allow to lead to during processing
It crosses fraction and carries out efficient raw material separation.
Method closest to technical solution of the present invention is the method for raw mineral materials pneumatically separated (referring to Eurasian patent
No. 022959,0 З В 4/04,2016 of class В 07 В 4/08, В), comprising: raw material is placed in air-permeable surface, raw material is ventilative
It is separated on surface, which promotes light fraction, Hou Zheshi from air-permeable surface through vertical (separation) chamber, ascending air
Pass through the lower section of the bottom of vertically separated chamber in the form of conveyer, wherein by selecting the speed of air stream, by specific close
The particle of degree forms diluted fluidized-bed layer, and the lower particle of density is into and through as the air-flow of rising is from vertical point
Foregoing description particle in gravity sedimentation chamber is transferred to from chamber to pass through in unencumbered situation.
This method allows annual outdoors or using the progress raw material separation of sunlight builder's temporary shed；Meanwhile by converting gas velocity
The mode of degree, to execute the quick readjustment of manufacturing process, to handle various types of raw mineral materials.
The major defect of the ad hoc approach is to select the performance of the particle of predetermined size to be not enough, this is by following original
Because determining.
Firstly, when attempting to improve the performance of this method, it is necessary to be scaling up conveyor speed, which reduce pre- scales
Very little particle existing time in inlet end (nozzle) region of vertical chamber, also, which increase move on a conveyor
Particle kinetic energy horizontal velocity and horizontal component.
Secondly, the increase of conveyor speed is automatically led near the rear wall (along the conveyer direction of motion) of vertical chamber
The change and density for diluting fluidized-bed layer increase, this has upset the proper flow of the particle movement in false boiling bed (because increasing
The density of particle), preventing the particle compared with low-density, that is, this causes heavier particle to remove light particle and reduces by it
The performance of separation process.
Summary of the invention
Basic purpose of the invention is to improve the performance and holding separation process performance of ad hoc approach.
The specific purposes of the method for pneumatic separation raw mineral materials include: that raw material to be separated is placed in air-permeable surface,
The air-permeable surface runs through split cavity, wherein the air-flow risen promotes light fraction from air-permeable surface, the latter is with conveyer
Form pass through the lower section of the split cavity bottom, wherein by selecting air velocity, diluted fluidized-bed layer is by specific close
The particle of degree is formed, and wherein density smaller particle is raised without hindrance before air stream is transferred to gravity sedimentation chamber from split cavity
It is tilted into and through, which is characterized in that the split cavity towards conveyer plane with hindering, and its bottom is parallel to conveying
Machine plane, and the direction of motion of the acute angle direction conveyer formed by the longitudinal wall of split cavity and its bottom.
Specific position due to split cavity and its bottom relative to conveyor surface is shown when increasing conveyor speed
The density for writing the fluidized-bed layer of the rear wall (along the conveyer direction of motion) of reduction split cavity nearby, thus in the whole of split cavity
Being more evenly distributed in a cross section.
In order to increase the extraction degree of the particle with predetermined density, the split cavity is by internal longitudinal parallel subregion point
At the part of two or more sequences and/or parallel positioning, and the bottom of these parts is parallel to conveyer plane, and
And the upper end of these parts merges together in split cavity, and particle is transmitted to gravity sedimentation chamber by single air-flow.
This is because being specified for separating particle by scheduled gravity value, to the multistage of specified particle in split cavity
Selection is achieved in that through several continuous perpendicular flows to specific particle while having an impact, each perpendicular flow
Absorb the specific particle in its specified portions.
Known split cavity selection density is lower than the particle of pre-set density, such as 1.4 grams/cc.It is only to be separated
Material may comprising big metric density be less than isolated particle, split cavity be divided into identical or different cross-sectional area
Part, and equal or different flow velocity is respectively provided with inside them, will allow with have the particle lower than predetermined density into
The interim separation of row, to reduce the load of back chamber and improve the separation effect that density reaches 1.4 grams/cc of particle
Rate.
In order to carry out multistage selection to the particle with predetermined gravity, the bottom of the different piece of split cavity is being conveyed
It can have identical or different setting height above machine, so that it is guaranteed that being formed in each part of split cavity identical or different
The fluidized-bed layer of density, this will allow to ensure that density is substantially less than of preset density in the first part of split cavity
The pre-separation of grain, and in last part, execute more acurrate and the effectively particle based on density separation.
Split cavity is divided into multiple portions along the conveyer direction of motion, is allowed in the cross section in split cavity
The inhomogeneities of the air's velocity field of (along conveyer) removal, and the chamber is divided into across the conveyer direction of motion more
A part, so that transversal cross-section and longitudinal cross-section (perpendicular to conveyor direction) in split cavity be allowed to eliminate air velocity
The inhomogeneities of field, and prevent the horizontal and vertical cross flow one of the particle of fluidized-bed layer and ensure it in entire chamber portion
Uniformity in point.It is square proportional to realize this effect due to gas-flow resistance and the flow velocity in channel, also, point
Not, in the higher channel of original speed, the obstruction that flow velocity is subject to is bigger, and minimum is hindered in the smallest channel of speed, because
This, the average value of the flow velocity in each channel close to entire split cavity.
Therefore, split cavity is installed into has a certain degree with conveyer plane, and its bottom plane is located at and conveying
The parallel position of machine plane improves disclosed method with allowing substantially (twice and more) compared with prior art
Performance.The selectivity for keeping or even improving the Pneumatic method for raw mineral materials separation simultaneously, be applied at present it is pneumatic
The known method of separator is dissimilar, and therefore, it meets the standard of " creativeness ".

Specific embodiment
In order to understand stated method, firstly, letting us consider that the process occurred in separating vertical chamber, such as Fig. 1
Shown, the particle 4 of raw material is separated, and is moved in ventilative belt conveyor 3.The particle of most thin passes through 3 mistake of conveyer
It filters and (is filtered by conveyer 3 and do not illustrated with the process for the particle for conditionally removing spilling by being removed from particle separated region
It shows to property).Then, the particle 4 that is moved on conveyer 3 reach separate vertical chamber enter region, this enter region by
Wall 1 limits, and is inhaled into air stream 2 by its open bottom opening 5 in this particle 4.Therefore, with separate vertical chamber
The adjacent region of open bottom 5, the vortex of mobile particle 6a-6e occurs, passes through horizontal energy and hits 4 shape of particle simultaneously
At the vertical lifting force that this is created with their movements on belt conveyor 3 and by air stream 2 is related.Mobile part 6
The specific flowing of а -6f forms fluidized-bed layer by the particle of preset density, and it is preset to be less than this for density wherein
The particle of density passes through without restriction；Then, they are transmitted to from vertical chamber by admission line 8 by the air-flow risen
Gravity sedimentation chamber 7 provides gas handling system 9 and forms particle 4 into required negative pressure (rarefaction).In gravity sedimentation chamber
In room 7 after accumulating particulate, opens gate mouth 10 and remove the particle of deposition.The gravity of the particle of fluidized-bed layer is formed by air
Flow velocity 2 is preset.Under the harmonic motion speed conditions of belt conveyor 3, therefore, the performance of this method is low, and particle is fluidizing
Distribution layer in bed corresponds to Fig. 2 a；Also, in the increased situation of conveyor speed 3, particle carries out as shown in Figure 2 b
Rear (moving along the conveyer) wall of distribution, i.e. fluidized-bed layer towards vertical chamber is displaced.Divide however, reducing in vertical chamber
Performance from process.This can be by the fact that explain: when particle 4 is mobile, is flowed in fluidized-bed layer, this
It ensures and is separated by the particle of gravity and parasitic flow.Thus, for example, the light granules moved along path 6g can be with edge
The particle contact of path 6d mobile high gravity, and in this respect in view of the availability of the horizontal velocity of particle 6d and its
Higher density, these particles may remove along the path 6g this particle moved and from split cavity it in tow.
Therefore, when the movement velocity of gas permeability conveyer 3 increases, it will be observed that particle separating property in split cavity
It reduces.In this respect, allowing the unique method for improving the pneumatic separating property of raw mineral materials is the movement for increasing gas permeability conveyer 3
Speed.In order to solve the particular problem, it is proposed that being positioned as split cavity with angle, as shown in Figure 3.Due to being inhaled into
The region 16 of bed is greater than the region 5 (Fig. 1) of vertically separated chamber, and the wall 12a of split cavity is tilted towards conveyer, however,
The movement of particle in fluidized-bed layer is formed by two flowings: along the angled wall 12a upper up-flow guided and towards angulation
The vertical current of the wall 12b decline of degree, this leads to the organized circulation of particle.Therefore, the fluidized bed under particle stream 17a shock
Layer (moves) wall 12b displacement before along conveyer, thus, plane of the fluidized-bed layer relative to the bottom 16 of split cavity
Whole region is horizontal.
In order to improve the extraction degree with preset density granule, the split cavity can pass through longitudinal baffle quilt
Be separated into two or more parts (referring to fig. 4) being continuously arranged, 20 а -20b of bottom be parallel to the screen of conveyer and and it
Keep identical distance.Following example can explain specific effect.It lets it is assumed that in the activity pattern in split cavity,
90% efficiency may be implemented in one split cavity, i.e., constitutes in 10% from chamber and remove light granules.Therefore, in first portion
In point, we can extract 90% light granules, in the second part-enter those of second part light granules
90% or more, i.e., the collective effectiveness separated in two continuous parts is up to 99%, in terms of separating property, a part
Equal to 90%.The solution allows for the significant increase of conveyer movement velocity and the performance for the method stated.
Now, the variant embodiment for implementing method shown in Fig. 5 is let us consider that, wherein using the chamber of three parts；Respectively
The bottom of a part is located at the height different from chamber surfaces.Specific method allows to ensure in this way in split cavity
Fluidized-bed layer is distributed in part so that have compared with low-density fluidized-bed layer conveyer first part (towards conveyer
Movement) in extract density and be significantly less than a large amount of particle of preset threshold density, to reduce the load to aft section,
In finally remove the particle close to the preset threshold density.
Fig. 6 shows another variant embodiment of the method, and the chamber of inclination separation multiple portions is shown.
It includes three part 43'-45' continuously installed, they are arranged along conveyer 42 and three parts sequentially installed
43 " -43 " ", they transverse to conveyer, the bottom of all parts is set to relative to the identical height of conveyer 42.Disengagement chamber
This arrangement of indoor section allows while ensuring the uniformity of fluidized-bed layer, either in the longitudinal of vertical cavity or in cross
Into part.Fig. 7 shows the raw mineral materials particle of separation in part 43 " -43 " " in distribution, they are laterally positioned in conveyer
On 42.
In order to actually realize the method, prototype plant is manufactured, for separating the waste of ferrochrome production, it is intended to further
Obtain ferrochrome.Separation process is moved in the separation enterprising promoting the circulation of qi of inclined chamber, which is continuously partially formed by 3
(Fig. 4), and 55 ° are constituted with the inclination angle of conveyer plane.Before pneumatic processing starts, waste is tentatively ground to coarse
Degree is 0-6 millimeters, and is supplied to belt conveyor, and the band of conveyer is made of grid, and grid is 1 millimeter, and width is 600 millis
Rice, travel speed are 0.5-1.5 meter per second.The cross section for tilting split cavity is 600 × 150 millimeters, is highly 900 millimeters, and
It is divided into 3 mutually prismatic parts by partition.Chamber is highly 2500 millimeters by air pipeline and 1200 millimeters of diameter
The connection of gravity sedimentation chamber.The air stream in split cavity is selected, so that generation is free of ferrochrome pearl in the chamber and gravity is small
In the product of 2.9-3.5 tons/cubic meter, and retain the crome metal for containing micro field trash on the conveyer after by chamber
Iron；It is vendible concentrate.With the single rectangular vertical point with 600 × 150 millimeters of section and 900 millimeters of height
