Abstract
The utility model relates to a screening separator used for magnetic materials and non-magnetic materials. The device is composed of a feeding system, a discharge system and a magnetic field groove (3) which can generate the moving magnetic field and is provided with a protective layer. The device is characterized in that the utility model utilizes the principle of magnetic field movement. Therefore, the equipment itself has no the movement of mechanical elements. Because the moving magnetic field of the device can drag the magnetic materials and the non-magnetic materials to make single particle movement toward different directions, the purity of the screened materials is improved.
Description
The utility model relates to a kind of material separation device, particularly is applicable to the magnetic material screening machine in the ore-dressing technique of metallurgical mine.
Ore-dressing technique in the at present domestic and international iron and steel industry generally all adopts the fixed magnetic field of permanent magnetic system to carry out ore dressing.When material movement, magnetic material is adsorbed on the magnetic pole, utilizes mechanical movement to make magnetic material break away from magnetic pole after acquiring a certain degree and separated.But this technology inevitably with many non-magnetic materials, is wrapped in the magnetic material and is attracted on the magnetic pole together in adsorption process.Reason is that these non-magnetic materials and magnetic material mix and form due to magnetic linkage and the magnetic group.Feed purity after the magnetic separation is descended, thereby cause product quality to descend.
The purpose of this utility model in order to improve the purity of material after the magnetic separation, provides a kind of magnetic material screening machine that is made of moving magnetic field exactly, and this machine can screen different magnetic materials.Because this machine is to utilize Movement in Magnetic Field to drag the magnetic material motion, so the movement-less part of equipment own.Utilize moving magnetic field that magnetic material is screened, can make magnetic material do the individual particle motion and leave non-magnetic material, be difficult for producing magnetic group and magnetic linkage, guaranteed the purity of screening back material.
Above-mentioned purpose of the present utility model is achieved in that utilizes high-speed motion magnetic field can drag the principle of powdery magnetic material motion, has designed the magnetic material screening machine that a magnetic field groove that structurally includes feed system and discharge system and be made up of secured core winding and overcoat is constituted.This machine can make powdery magnetic material and non-magnetic material or the weakly magnetic material magnetic material screening machine from the motion of two different directions.
Below in conjunction with accompanying drawing, structure of the present utility model and embodiment are described in detail.
Fig. 1: be front view of the present utility model;
Fig. 2: be side view of the present utility model;
Fig. 3: be the A among Fig. 1-A cutaway view;
Fig. 4: be the B portion enlarged drawing among Fig. 3;
Fig. 5: be the C among Fig. 3-C cutaway view.
Among the figure: 1 magnetic material outlet; 2 non-magnetic material outlets; 3 magnetic field grooves; 4 feed motors; 5 storage bins; 6 blowing gates; 7 dispensers; 8 feed hoppers; 9 electric cabinets; 10 groove edges; 11 compound chutes; 12 magnetic material chutes; 13 magnetic field channel cores; 14 magnetic field groove windings; 15 iron core shims; 16 winding insulations; 17 protective layers; 18 slot wedges.
The discharge system that the feeding system that the utility model mainly is made up of dispenser 7, feed hopper 8, feed motor 4 and storage bin 5, blowing gate 6, material outlet pipe 1 and 2 are formed constitutes, and is equipped with a magnetic field groove between the feed hopper 8 of feeding system and material outlet pipe 1,2.
Said magnetic field groove is to be tied with winding 14 and iron core shim 15 formations that lead is formed at fixing iron core 13, on the surface of winding 14, be provided with winding insulation 16, on winding 14 and iron core 13, be provided with the overcoat 17 that non-magnet material constitutes, as shown in Figure 3 and Figure 4.
When granular material by storage bin 5 in; emit from blowing gate 6; the dispenser 7 that drives through charging motor 4 drops on the protective layer 17 of magnetic field groove 3 by feed hopper 8; because magnetic field groove 3 inclination certain angles (35 °-40 °); granular material freely moves downward because of gravity acts on the compound chute 11; at the same time; magnetic field groove 3 will produce one by the magnetic field of centre to two lateral movements; this moving magnetic field will drag magnetic-particle in the granular material on the protective layer 17 to groove along 10 liang of lateral movements; and cross groove and fall in the magnetic material chute 12 along 10; thereby make it to separate with non-magnetic material or weakly magnetic material; reached the screened purpose of coming out of the magnetic material that will mix in the granular material; because moving magnetic field drags the magnetic material motion of individual particle; so be not easy to produce magnetic group and magnetic linkage, guaranteed the purity and the significantly magnetic classification of magnetic material.
Use the utility model and carry out the screening of magnetic material, small investment, instant effect, effect is more obvious when particularly carrying out dry separation, is applicable to the further purification of fine iron breeze more.Spoil reclaming to some iron ore concentrate ore dressing plants also has certain applicability simultaneously, when iron content in the mine tailing is 20%, can once reclaim 5% grade and be 65% iron ore concentrate.
