Description
The present invention relates to a kind of magnetic screening machine, be applicable to the screening and the magnetic separation of particulate magnetic material, be particularly suitable for the preparation of ultrapure magnetite powder.
Traditional screening operation, generally by means of mechanical force produce vibration, mode such as rotate or shake comes the loose material bed of material, material particles utilization deadweight is passed through sieve aperture and is reached the purpose of screening, its screen cloth serious wear, screen cloth stops up easily, screening efficiency is low.And traditional magnetic concentration working because the magnetic rolling efficient of material is very low, is difficult to destroy the magnetic coagulation effect of material, makes the mineral of selecting be mingled with some non-magnetic materials, and especially the mineral with the intergrowth of nonmagnetics more are difficult to sorting.
The objective of the invention is to propose a kind of effect, carry out a kind of magnetic screening machine of the screening and the magnetic separation of material simultaneously by means of alternating magnetic field in order to overcome the shortcoming of above-mentioned technology.
A kind of magnetic screening machine comprises:
The moving magnetic of-alternation system, the moving magnetic of this alternation system is packed on the axle, places and selects the plate inboard, and the magnetic pole of the moving magnetic of alternation system is along circumferentially N, S alternately arrange;
-axle installs and supports the moving magnetic of alternation system on this axle, its two ends are packed on the support by means of bearing and bearing block, and this axle is dragged by motor;
-selecting plate, this selects plate is that cartridge type is selected plate, is packed in the outside of the moving magnetic of alternation system, it is that axis is identical with the moving magnetic of alternation that this cartridge type is selected the axis of plate;
-feed box, this feed box is arranged on the top of screen cloth;
-non-magnetic material gold, this material box is arranged on the below of selecting plate;
-magnetic material box, this material box is arranged on the side of nonmagnetics magazine;
-discharge rolls, this discharge rolls are arranged in the ore discharge district;
It is characterized in that:
A. select the outside of plate to be provided with screen cloth in cartridge type, this screen cloth places in the alternation moving field active region;
B. cartridge type is selected between plate and the moving magnetic of the alternation system and is left the gap, and both do relative motion mutually.
The moving magnetic of alternation system also can adopt the iron core that has groove to inlay the alternation magnetic system that the three-phase alternating current winding is formed.
Plane magnetic system can also be made by alternation magnetic system.
Owing to taked technique scheme, the present invention compared with the prior art, the machine of can realizing carries out the screening and the magnetic separation of material simultaneously, has the advantages that screening and efficiency of magnetic separation height, screen life-span are grown.
Fig. 1 is a kind of schematic diagram of magnetic screening machine.
Fig. 2 is that three-phase alternating current alternation magnetic is schematic diagram.
Fig. 3 is plane magnetic screening machine figure.
In conjunction with the accompanying drawings the present invention is further described as follows.
The present invention is combined as a whole screening plant and magnetic separator, and the machine of realizing carries out the screening and the magnetic separation of material simultaneously.
A kind of magnetic screening machine comprises: the moving magnetic of alternation is 4, and the moving magnetic of this alternation system is packed on the axle 8, places and selects in the plate 3, and the magnetic pole of the moving magnetic of alternation system is along circumferentially N, S alternately arrange; Axle 8 installs and supports the moving magnetic of alternation system on this axle, its two ends are packed on the support by means of bearing and bearing block, by being packed in the drive 7 on the axle, driving it by motor 10 and presses the rotation of Fig. 1 arrow A direction; Select plate 3, this selects plate is that cartridge type is selected plate, is arranged on the outside of the moving magnetic of alternation system, and leaves the gap between the moving magnetic of the alternation system, and this selects the axis of plate is that axis is identical with the moving magnetic of alternation, selects plate to be driven by motor 11, does relative moving mutually with the moving magnetic of alternation system; Feed box 6, this feed box is arranged on the top of screen cloth 1; Nonmagnetics magazine 14, this material box is arranged on the below of selecting plate; Magnetic material box 13, this material box is arranged on the side of nonmagnetics magazine; Discharge rolls 9, this discharge rolls Surface Machining has roller seating space, guarantees that there is powerful magnetic induction on the discharge rolls surface, is beneficial to remove the magnetic material that selects the plate surface, and this discharge rolls places in the ore discharge district, is dragged by motor 12; It is characterized in that: a. cartridge type selects the plate outside to be provided with screen cloth 1, and this screen cloth is packed on the screen cloth support 2, places in the alternation moving field active region; B. cartridge type is selected between plate and the moving magnetic of the alternation system and is left the gap, and both do relative motion mutually.
When magnetic material 5 when feed box 6 is given on the screen cloth, it is the effect of magnetic force that the particle of magnetic material is subjected to the moving magnetic of alternation, when stirring along screen cloth, the suitable particle of particle diameter is subjected to the attraction of magnetic force and the effect of material self gravitation, passes sieve aperture and falls into and select the plate surface.Particle diameter enters in the mixing magazine 15 greater than the particle of sieve aperture.Material under the screen cloth select plate surface continue by Fig. 1 in the arrow B direction make magnetic rolling, constantly destroy the magnetic coagulation effect, the non-magnetic material that will be mingled with is cast aside, and fall into non magnetic magazine 14, when magnetic-particle is rolled to discharge rolls 9 places, attracted by the induced magnetism of discharge rolls,, magnetic material is drained in the magnetic material box 13 by means of the centrifugal force of discharge rolls.
The moving magnetic of alternation system also can adopt the iron core that has groove to inlay the three-phase alternating current winding and make, as shown in Figure 2.This alternation magnetic system is formed by stacking by the fluted silicon steel sheet of peripheral band and forms iron core 17, is inlaid with three-phase alternating current winding 16 in groove.When winding feeds three-phase alternating current, around iron core, produce rotating excitation field, its function is identical with the moving magnetic of above-mentioned permanent magnetism alternation.
It is 4a that alternation magnetic system also can be made into plane magnetic, as shown in Figure 3.Its iron core 17a one side has groove, inlays three-phase alternating current winding 16a in the groove.After connecting three phase mains, produce a parallel mobile electromagnetic field in iron core winding one side, above plane magnetic system, be provided with board-like plate 3a and the planar shaped screen cloth 1a of selecting, screen cloth is fixed on screen cloth support 2a, and placing plane magnetic is in the active region.When magnetic material 5 when feed box 6a is given to planar shaped screen cloth 1a and goes up, part is mingled with non-magnetic material and directly falls into nonmagnetics magazine 14a, magnetic material is because plane magnetic system produces the effect of parallel shifting magnetic field, move upward along the planar shaped screen cloth, meanwhile, the material that granularity is suitable passes sieve aperture and falls board-like the choosing on the plate 3a, and the coarse-grained material on the planar shaped screen cloth is collected among the magnetic material box 13a.Board-likely select the fine on the plate to move to magnetic material box 13b, and non-magnetic material slip among the non magnetic magazine 14b along the board-like plate slope of selecting because of the gravity effect by the direction of Fig. 3 arrow B.
