Description of drawings
Fig. 1 is a structural representation of the present invention.
The specific embodiment
Below in conjunction with specific embodiment and accompanying drawing the present invention is further described.
As shown in Figure 1, a kind of dry-type magnetic extractor comprises that feed pipe 1, conveyer belt, belt claim 3, dust catcher 4, magnetic wheel 5, dust cover 6, air blast 8, inflatable shaking chute 9, magnetic are 10, belt pulley 14.
Conveyer belt drives through belt pulley 14 and magnetic wheel 5; Conveyer belt is divided into feeding section 2 and magnetic separation section; It is 10 that magnetic separation section inboard is provided with magnetic; Magnetic wheel 5 is located at feeding section 2 and is turned to the corner of magnetic separation section inboard, and the magnetic separation section is followed successively by the section of roughly selecting 15, selected section 11 of circular arc and concentrate feeding section 16 along flow direction of material, and the section of roughly selecting 15 below correspondences are provided with inflatable shaking chute 9.Be uniformly distributed with some micropores on the working face of said inflatable shaking chute 9, inflatable shaking chute 9 connects air blast 8, and air blast 8 provides air-supply to be ejected in inflatable shaking chute 9 working faces from micropore and forms inflatable air cushion.Material is when inflatable shaking chute 9 working faces, and upset on air cushion, vibration not only make the bottom material by fully magnetic separation, and Flow of Goods and Materials speeds up, and makes the treating capacity of material strengthen.
On the feeding section 2 of said conveyer belt feed pipe 1 is arranged, near feeding section 2 belows of feed pipe 1 belt conveyer scale 3 is set, belt claims that 3 are used for confirming the amount of convey materials, mating follow-up mass flow, and can save a feeding machine, has reduced cost.Feeding section 2 arranged outside dust catchers 4 are used to siphon away airborne dust, can be beneficial to magnetic material and separate with non-magnetic material fully by magnetic separation after making magnetic material exposed.Whole magnetic separator arranged outside dust cover 6 is used to prevent the dust contaminated environment that flies out.
The feeding section 2 of said conveyer belt turns to the corner of magnetic separation section to be provided with first and throws tail mouth 7, and inflatable shaking chute 9 afterbodys are provided with second and throw tail mouth 12, and concentrate feeding section 16 afterbodys are provided with concentrate mouth 13.
Parameter of the present invention is chosen as:
The wide of shaking chute 9 is 1-10m, long is 2-20m, the inclination angle be 1-45 ° adjustable, Oscillation Amplitude is 0.1-30mm, vibration frequency 1-3000Hz; The amount of passing through of feed pipe 1 be the 30-300 ton/hour; The diameter of magnetic wheel 5 is 0.1-1m; The width of conveyer belt is 1-10m, and length is 2-20m; The air quantity of dust catcher 4 is greater than 10000L/min; Selected section 11 radius 0.1-1m of circular arc.
Technical process of the present invention is:
According to the requirement that roughly select in the magnetic ore deposit or the magnetic ore deposit is selected, select different magnetic field intensity and material size.Carry out the magnetic ore deposit when roughly selecting, the control material size is less than 5mm, and magnetic field intensity is controlled at 1200Gs-3000Gs.Sorted materials gets into magnetic separator from feed pipe 1, on conveyer belt, flows, and claims that through belt 3 flow to magnetic wheel 5, and dust catcher 4 siphons away airborne dust, and dust cover 6 flies out in order to prevent dust, influences environment.Change the material traffic direction when material flows to magnetic wheel 5 and get into the section of roughly selecting 15, be adsorbed on magnetic material and make the layering of sorting property of material on the belt, be beneficial to follow-up sorting; A part of non-magnetic material carries out throwing the first time tail herein, and mine tailing is thrown into first and throws tail mouth 7, can throw 10%; Rest materials continues to flow with belt, and magnetic material is that 10 effects are adsorbed on down below the belt at magnetic, and non-magnetic material is mobile on inflatable shaking chute 9; Air blast 8 provides air-supply on the skewed slot working face, to form inflatable air cushion and cooperates the vibration of skewed slot, and the fine powder in the material can not sunk to the bottom, and material fully stirs; Magnetic material is chosen fully; The rate of recovery reaches more than 99%, and Flow of Goods and Materials is speeded up, thereby the treating capacity of material is strengthened.The vibration frequency of inflatable shaking chute 9 is adjustable to adapt to the material of different grain size and grade.Material passed through selected section of circular arcs at 11 o'clock along the section of roughly selecting 15; Material forms circular motion; Material is under action of centrifugal force; The material of article potential difference is left is throwing tail on the inflatable shaking chute 9 when second throws tail mouth 12, throw the tail amount and reach 50%, and remaining concentrate of high grade is delivered to concentrate mouth 13 by concentrate feeding section 16 and collects.
Carry out the magnetic ore deposit when selected, the control material size is less than 0.075mm (200 order), and magnetic field intensity is controlled at 600Gs-1200Gs.All the other are consistent when roughly selecting with the magnetic ore deposit, repeat no more at this.
Therefore, adopt dry-type magnetic extractor of the present invention to carry out choosing of magnetic material, magnetic material can be chosen fully, can carry out the magnetic separation in high-grade magnetic ore deposit, and grade can reach 30%-60%, throws the tail amount more than 50%.And this dry type magnetic separator is simple in structure, compact, adopts the inflation of band vibration to carry skewed slot, chooses fast, and treating capacity is big.
The above is merely preferred embodiment of the present invention, not in order to restriction the present invention, all any modifications of within spirit of the present invention and principle, being done, is equal to and replaces and improvement etc., all should be included within protection scope of the present invention.
