Description
Technical field
The present invention relates to a kind of magnetic separating device, particularly a kind of superconducting magnetic separation device that can be used for ore dressing.
Background technology
Since the magnetic separating device that nineteen thirty-seven Fu Langzi invention ore dressing is used, magnetic separation ore-sorting technology has obtained significant development.Particularly superconducting magnetic separation device drops into the mine and already uses over more than 30 year, and superconductor technology and magnetic separation technique constantly develop, and interpenetrate, and merges each other and promotes, makes the magnetic separation technique range of application more and more wider.The fast development of magnetic separation ore-sorting technology is based on several kinds of reasons:
1, magnetic separation ore-sorting technology is a kind of physical separation method, compares with chemical method, and magnetic separation technique technology is simple, environmentally safe, compliance with environmental protection requirements.
2, from world wide, the rich ore that iron-holder is high is fewer and feweri, and a large amount of lean ores and mine tailing wait for and recycling that magnetic separates and can play a great role.
3, along with the development of superconductor technology, superconductor technology has been moved towards application and has been combined with magnetic separation technique from the laboratory, and superconduction magnetic separation magnet uses superconducting line, and resistance is zero, and operate power is low, greatly energy savings.
Magnetic-particle receives the effect of magnetic force in the space of changes of magnetic field, the big I of magnetic force is expressed as:
F
m＝KVHdH/dx
Wherein: the susceptibility of K-particle
The volume of V-particle
The H-magnetic field intensity
The dH/dx-magnetic field gradient
In same magnetic field, the material of different magnetic is stressed different, depends on the susceptibility of particle.The distance that the different material of magnetic is put in magnetic field gradient one lateral deviation is different, thereby reaches the purpose of separation.
In the filtering type magnetic separating device, the captive primary condition of magnetic-particle is magnetic force F
mGreater than gravity F
gWith fluid viscosity resistance F
DYet, can find out by following formula, for specific magnetic separating device since its magnetic field intensity fix, so the volume of the particle that can separate through magnetic separation-be that the sorting scope also is certain.Existing often lead the high gradient magnetic separator background magnetic field and be bordering on 1T, iron particle that can sorting is basically more than 50 μ m.
China's high-grad iron ore deposit resource is few, and hematite and bloodstone resource are many, account for total resources more than 60%.And the fine grained ore below the 30 μ m utilizes the existing magnetic separator of often leading not separate, and a large amount of resources is not used on the one hand, causes very big environmental problem on the other hand.
In addition, China's aluminium oxide industry yearly productive capacity is through nearly 3,000 ten thousand tons.Usually contain more iron in the bauxitic feed materials, the residue that the extraction aluminium oxide stays later on is called as red mud (taking on a red color owing to containing iron oxide, so claim red mud).Iron content reaches 20-30% by weight percentage usually approximately in the red mud, sometimes up to about 50%.Because the needs of technology, it is very thin that bauxite generally will grind, and particle over half is below 20 μ m.Therefore utilize conventional magnetic separator also to be difficult to separate.
And superconducting magnet has higher magnetic field intensity, generally can reach 3-5T, but the iron grain diameter of sorting is 10 μ m left and right sides susceptibilitys 5 * 10 in theory
-2～5 * 10
-6Cm
3The weak magnetic bodies of the granule of/g.
The industrial high-intensity magnetic field that Outokumpu technology Co., Ltd produces filters the High-gradient Magnetic seperator, is mainly used in kaolinic purification and brightens, and it adopts is solenoid superconducting magnet, treatment system back and forth jar.Owing to adopt reciprocal pot type, be interrupted charging and discharging, therefore belong to the Batch Process mode, the shortcoming of Batch Process is low, the complicated operation of production efficiency.This in addition magnetic separator will be adopted steel wool, and the gap between the steel wool is easy to stop up, and this also makes the treating capacity step-down of seperator.So, can obtain good effect though this superconduction magnetic separator is used for the removal of impurities of kaolin trace iron magnetic material, when being used for selecting iron ore and being used for red mud and extracting iron ore from poor body ore deposit; Then owing to iron content in these materials is high; So the amount of iron ores of separating is bigger, and it is faster to make that steel wool stops up, and running time is too short; Efficient is too low, is difficult to be applied to the iron ore sorting.
And the magnetic separator of horizontal plane rotating disk or vertical dial mode then can not be used the solenoid superconducting magnet, is generally permanent magnet or normal magnetic conduction iron, and magnetic field intensity and gradient are lower, thereby are difficult to separate with the subparticle mineral for weak magnetic-particle.

The specific embodiment
Through specific embodiment the present invention is described in further detail below, to help understanding content of the present invention.
As shown in Figure 1 is a kind of superconducting magnetic separation device, comprising:
4 the present invention of solenoid type superconducting magnet adopt the solenoid type superconducting magnet; In its room temperature aperture; Magnetic field intensity is even basically on axis, and the center divides magnetic field, constituency generally at 4～6T, and the solenoid winding of superconductor coiled is by liquid helium cooling (temperature is 4.2K); The periphery of superconduction winding surrounds with a high vacuum layer, a 40K thermal barrier and 1～2 group of multilayer heat insulation layer, and keeps liquid helium with a 4K refrigerator.The magnetic field, branch constituency that has 4～6T in this superconducting magnet room temperature hole is sorting 10 μ m left and right sides susceptibilitys 5 * 10
-2～5 * 10

3The weak magnetic bodies of the granule of/g has been created magnetic field condition.
Also comprise main drive wheel 1 and driven pulley 10, the screen mesh type conveyer belt 2 of annular closure rotates under driving at main drive wheel 1 on main drive wheel 1 and driven pulley 10.The loading end of screen mesh type conveyer belt 2 is a screen cloth, and the room temperature hole 5 of superconducting magnet 4 is passed in some (middle part of conveyer belt upper level part among Fig. 1) in the screen mesh type conveyer belt 2, and other part is positioned at the superconducting magnet outside.If the screen mesh type conveyer belt about in the of 2 two parts all from the room temperature hole of superconducting magnet 4, pass, then need the room temperature bore dia bigger, and by the delivery ratio of the non magnetic breeze after the sorting the difficulty.
Be provided with the deflector 7 of the non magnetic breeze after the sorting being derived usefulness below in superconducting magnet room temperature hole 5, being positioned at screen mesh type conveyer belt 2, the deflector discharging opening extends to superconducting magnet 4 outsides.For ease of the breeze that sub-elects is flowed out in superconducting magnet room temperature hole 5 swimmingly; Deflector 7 as depicted in figs. 1 and 2 is obliquely installed along the magnet axis direction in superconducting magnet room temperature hole 5; And it is lower to be positioned at the superconducting magnet room temperature hole end that enters the mouth by conveyer belt 2 directions of advance, is provided with bath water pipe 6 ' so that non magnetic breeze is gone out at its higher end.Outside ultra magnetic conductance magnet, also has an inclined chute 9 so that breeze is exported from screen mesh type conveyer belt 2 sides.
Because at two ends, superconducting magnet room temperature hole, less with respect to the center magnetic flux density, magnetic field intensity is low; Sometimes do not reach the magnetic field intensity requirement that breeze separates, target Iron Ore Powder particle can't gather agglomerating or chain by magnetic, can directly fall the screen cloth below; Influence the efficiency of separation and effect; Therefore as shown in Figure 1, the feed pipe 3 of also oriented screen mesh type conveyer belt feeding, or charging inclined chute 29 as shown in Figure 9.Feed pipe 3 or charging inclined chute 29 discharging openings stretch in the room temperature hole; Make outlet be positioned at the position that superconducting magnet room temperature hole 5 internal magnetic field intensity reach the sorting requirement; Usually reach the position that magnetic field intensity is 4T, directly leak down, improve sorting index to avoid at large the obtaining of vignite particle in the breeze.
Same reason; In superconducting magnet room temperature hole 5, exporting an end magnetic field intensity near the screen mesh type conveyer belt weakens; Might can leak down from screen cloth by captive breeze, so in superconducting magnet room temperature hole 5, export an end magnetic field intensity near the screen mesh type conveyer belt and weaken to forming the position that magnetic gathers group; Being positioned at conveyer belt below is provided with base plate 8 and extends to outside the superconducting magnet 4; Though between screen cloth and this base plate 8 certain interval is arranged, because the effect of scraper plate 21 can scrape breeze, by inclined chute 9 ' catch and derive from a side.Or it is as shown in Figure 9; Base plate 8 is obliquely installed; Outlet one end that base plate is lower is low to be extended to outside the superconducting magnet, and the ferromagnetism powder can be discharged the superconducting magnet room temperature hole automatically under the gravity effect like this, compares with the horizonal base plate mode of utilizing scraper plate to scrape among Fig. 1 to need not by other external force; And structure is easier, and it is also little to wear and tear.
Stop up for improving separating effect, efficient and minimizing screen cloth; As depicted in figs. 1 and 2, in superconducting magnet room temperature hole 5, be positioned at screen mesh type conveyer belt top position; Be provided with the spray header 6 to screen mesh type conveyer belt water spray, spray header 6 is provided with hole for water spraying towards the direction of conveyer belt 2.Spray header 6 can employing pipe as shown in Figure 2, also can be illustrated in figure 5 as special pipe, to obtain bigger coverage rate.Hole for water spraying can be flushed to non magnetic mineral powder granular below the screen cloth fast, and is beneficial to by deflector discharge room temperature hole.
Be positioned at said superconducting magnet room temperature hole, be positioned at screen mesh type conveyer belt dual-side below and be provided with the holder rail screen mesh type conveyer belt is upwards held.Holder rail 25 can be illustrated in figure 5 as two square or circular rod members or pipe fitting, also can as shown in Figure 2ly be positioned at superconducting magnet room temperature hole 5, adopts sorting groove 11 modes that the screen mesh type conveyer belt is held, and the sorting trench bottom is hollow out on magnet room temperature axially bored line direction.Sorting groove 11 with the screen mesh type conveyer belt under hold, and conveyer belt and breeze can only be moved forward along the sorting groove, and guarantee its smooth and easy slip, sorting groove 11 bottom openwork parts so that breeze leak down.
The loading end of screen mesh type conveyer belt is a screen cloth, because the weight that screen mesh type conveyer belt 2 will carry the bigger breeze of density, thereby and will have enough stretching resistances to realize running to be driven by main drive wheel, so conveyer belt needs enough tensile strength.Yet because the mineral powder granular that separates has only ten to tens microns, therefore so fine and closely woven mesh has determined that the intensity of screen cloth itself is limited.The conveyer belt structure that present embodiment adopts such as Fig. 2～shown in Figure 4; The screen mesh type conveyer belt by the polylith scraper plate 21 vertical with its direct of travel through the hinge 22 hinged chain structures that form; Screen cloth 23 is fixed between adjacent two scraper plates 21, a section circle that surrounds into.Hinge can also can all be provided with on scraper plate 21 both sides, so that balance in its stress balance and the moving process like Fig. 2, the scraper plate middle part that is positioned at shown in Figure 4.Utilize hinge and scraper plate, can reduce through main drive wheel 1 during with driven pulley 10 the conveyer belt bending screen cloth produced stress damage, screen cloth is as far as possible near the residing stressed position of hinge, screen cloth is not subject to stretcher strain when bending like this.The screen mesh type conveyer belt of this structure is to bear pulling force by hinge fraction, and the screen cloth 23 main breezes that carry.
As shown in Figures 2 and 3; Scraper plate 21 inwardly (the promptly closed inner space direction that conveyer belt surrounded) protrudes from hinge 22; This projection formation tooth one by one and the tooth engagement of main drive wheel among Fig. 11 and driven pulley 10; The tooth pitch of main drive wheel 1 and driven pulley 10 is identical with the scraper plate pitch or be its integral multiple, and screen mesh type conveyer belt 2 is turned round with the identical mode of linear velocity with main drive wheel 1 and driven pulley 10.
The screen mesh type conveyer belt also can be like Fig. 5 to shown in Figure 8; Mainly is made up of two chains 24 and screen cloth 23, for ease of the fixing of screen cloth with make screen cloth can bear the pulling force of material gravity generation, the screen mesh type conveyer belt comprises two chains; Article two, the parallel horizontal stripe 27 that is horizontally connected with as shown in Figure 7 between the corresponding chain link of chain; Gapped between the adjacent horizontal stripe 27, screen cloth is laid and is fixed on the horizontal stripe surface, utilizes the fixing and support screen cloth of horizontal stripe.Horizontal stripe can be as shown in Figure 6, adopts the axle 26 of having strong market potential of two chains of perforation of hinged usefulness between relative chain 24 chain links, and the axle of having strong market potential 26 can be circular shaft, or square shaft is so that screen cloth 23 fixing.Can be stripe board like Fig. 7 and horizontal stripe shown in Figure 8 27 also, two ends be riveted respectively or are welded on the relative chain link of two chains, and bolt pushed down and used to screen cloth 23 can with pressing plate 28.Horizontal stripe 27 not only plays fixed grit and mesh support screen effect, and can guarantee the equidistant and even running of two chains.This structure also can not adopt scraper plate.Main drive wheel and driven pulley then adopt sprocket wheel.
In superconducting magnet room temperature hole 5, the breeze that contains ferrimagnet is transported on the screen mesh type conveyer belt, under the effect of high-intensity magnetic field (the strong Tong Duchang in magnetic field is greater than 4T); Thereby ferromagnetic particle is magnetized to attract each other and forms magnetic linkage or magnetic group; Select the screen cloth of suitable width of mesh, thereby the size of this magnetic linkage or magnetic group is held by screen cloth greater than the screen cloth mesh, and its size of non magnetic particle is less than the mesh of screen cloth; Non-magnetic particle is then process under the momentum effect of its gravity and water drops to screen cloth through the mesh crack below; And be transferred out superconducting magnet normal temperature hole, and the ferromagnetic particle on the screen cloth continues to move forward with the screen mesh type conveyer belt, outside in superconducting magnet; Ferromagnetic particle is recovered, and has realized the continuous separation of produced of ferrimagnet.Owing to adopt superconducting magnet, can realize separating near 10 μ m left and right sides susceptibilitys 5 * 10 through the design magnetic field intensity
