Abstract
A magnetic system device of a high-gradient magnetic separator comprises an upper magnetic pole, a lower magnetic pole, an exciting coil and an end magnet yoke. The upper magnetic pole and the lower magnetic pole are provided with plane type acting surfaces capable of enabling magnetic lines of force in sorting regions to be distributed in the same direction, and magnetic fields in sorting cavities are distributed evenly. The magnetic system device overcomes the defect that cambered acting surfaces of an upper magnetic pole and a lower magnetic pole of a vertical ring pulse high-gradient magnetic separator enable magnetic fields inside sorting cavities to be distributed unevenly. In addition, compared with the vertical ring pulse high-gradient magnetic separator, handling capacity and magnetic field utilizing rate of the high-gradient magnetic separator are improved obviously. Due to the fact that the magnetic fields in the sorting cavities are distributed evenly, grading indexes of the magnetic system device are reduced obviously compared with tailings grade of the vertical ring pulse high-gradient magnetic separator, and the recovery rate is improved obviously.
Description
Technical field
The utility model belongs to the preparation equipment field, particularly relates to a kind of high gradient magnetic separator.
Background technology
The magnetic pastern branch of high gradient magnetic separator is the center that produces and provide magnetic source; Important component part for complete machine; The last lower magnetic pole acting surface of the pulsating high gradient magnetic separator with vertical ring of extensive use at present is arc surface, and is as shown in Figure 1, so the sorting cavity is the space of an arc.Its sorting inside cavity is as shown in Figure 2 along the Distribution of Magnetic Field of center line, can find out, the Distribution of Magnetic Field in arc sorting cavity on the center line is parabola shaped, and promptly sorting cavity central magnetic field intensity is high, and the both sides magnetic field intensity is low.This distribution mode of magnetic field intensity is disadvantageous to sorting of mineral; Centre at the sorting cavity; The mineral of fine grained and weak magnetic are attracted to the surface of magnetic matrix, but in medium goes to separation ring during the mining area because the magnetic field intensity reduction, the particulate weak magnetic mineral that is adsorbed on the magnetic matrix can turn back in the mine tailing again; Cause the grade of mine tailing to raise, reduced the sorting index of equipment.
Summary of the invention
The purpose of the utility model is the existence to the problems referred to above, and the magnetic that provides a kind of and can effectively solve high gradient magnetic separator arc sorting cavity internal magnetic field problem pockety, has the pulsating high gradient magnetic separator of uniform magnetic field distribution is device.
The purpose of the utility model realizes through following technical scheme:
A kind of magnetic of high gradient magnetic separator is device; Comprise magnetic pole, lower magnetic pole, magnetizing coil, end yoke; Be characterized in that said magnetic pole and the lower magnetic pole gone up is provided with and can makes that magnetic line of force trend is unidirectional plane acting surface in the branchs favored area of place, and the interior magnetic field of said sorting cavity distributes evenly.
Wherein, above-mentioned sorting chamber body structure is cuboid or square, and the trend of the magnetic line of force is vertical direction or horizontal direction in this sorting cavity.
Above-mentioned magnetizing coil is at least one, and this magnetizing coil is arranged in any position of magnetic system.
Above-mentioned sorting chamber body is positioned at the centre of magnetic system or the periphery of magnetic system.
The utility model is owing to adopted the magnetic architecture that can produce the uniform magnetic field distribution; Overcome original vertical ring high-gradient magnetic separator sorting cavity internal magnetic field shortcoming pockety; Make whole sorting cavity internal magnetic field be evenly distributed; The magnetisable material that is adsorbed on the dielectric rod can not come off in sorting cavity scope, has reduced tailings grade effectively, has improved the rate of recovery.Simultaneously owing to be positioned at the medium volume in sorting cavity high field intensity zone and compare and have vertical ring high-gradient magnetic separator now increase is by a relatively large margin arranged, the treating capacity of equipment also can be significantly improved.
Describe the realization of the utility model in detail below in conjunction with accompanying drawing.
