Description

Permanent-magnet high gradient ore separators magnetic group structure
Technical field:
The present invention relates to separate particularly a kind of magnetic group structure of using on the permanent-magnet high gradient ore separators that is applicable to.
Background technology:
At present, in China a large amount of weak magnetic refractory iron ores and the mine tailing that contains weakly magnetic iron ore are arranged, existing magnetic separator has electric magnetic separator and permanent magnetic roll assembly of roll magnetic separator magnetic separator; The electromagnetic field intensity of electricity magnetic separator can reach 20,000 Gausses; But because its ore dressing principle does not reach the ore dressing requirement, concentrate grade is low.The permanent magnetic roll assembly of roll magnetic separator ore separators is that the magnet and the magnetic conductive board magnetic field intensity of on the roller surface, arranging can reach 10000 Gausses, can only carry out sorting to the coarse granule weakly magnetic mineral, because magnetic group unreasonable structure; Make ore and magnetic field contact area little, so the rate of recovery is low, the article potential difference; In the actual production utilization; Adopt this machine often need unite other ore-dressing techniques to weakly magnetic mineral and could accomplish, owing to complex process, equipment is many, investment is big, has increased beneficiation cost greatly; And when ore-dressing practice, also can produce certain chemical contamination, be difficult to promote.
Summary of the invention:
The purpose of this invention is to provide a kind of simple in structure, investment is little, organic efficiency is high, the magnetic group structure that the permanent-magnet high gradient ore separators that is easy to promote is used.
Technical scheme of the present invention is accomplished as follows; It comprises some block permanent magnets and magnetic stripe fixed head; It is characterized in that: on the magnetic stripe fixed head, be equipped with side by side many respectively by polylith permanent magnet homopolarity to the permanent magnetic strip that connects into of contact side by side; The magnetic pole same sex between each adjacent two permanent magnetic strip arranges into the combination magnetic sheet relatively; Upwards lead to a magnetic conductive board between each bar composite poles respectively, above the magnetic stripe fixed head, leave a magnetic separation passage, correspondingly with each magnetic conductive board above the magnetic separation passage be provided with magnet fixed head on many; Magnet fixed head bottom is fixed with respectively by polylith permanent magnet homopolarity to being arranged in the magnetic stripe on the combination on each; The pole orientation that magnetic stripe is gone up in each combination is opposite with corresponding magnetic conductive board magnetic pole, and the periphery of magnetic stripe has sealed one deck barricade respectively on each, and magnet fixed head end face is separately installed with the lift adjustment screw on each.On each the bottom surface of magnetic stripe be respectively equipped with the water-tight layer above the magnetic stripe fixed head that assembles.The ore dressing passage that this magnetic group structure can be installed in ramp type permanent magnetism ore separators and drum-type permanent magnetism ore separators is both sides up and down, have simple in structurely, and beneficiating efficiency is high, and cost is low, the advantage that is easy to promote.
Description of drawings:
Fig. 1 is a kind of magnetic group structural representation that is applicable to that the flat-plate type permanent-magnetic ore separators is used;
Fig. 2 is a kind of magnetic group structural representation that is applicable to that drum-type permanent magnetism ore separators is used;
Fig. 3 is the package assembly sketch map of the present invention when being installed on the flat-plate type permanent-magnetic ore separators;
Fig. 4 is the package assembly sketch map of the present invention when being installed on the drum-type permanent magnetism ore separators.
The specific embodiment:
Further describe embodiment in conjunction with accompanying drawing.The present invention is equipped with many to connect into combination permanent magnetic strip 6 by polylith permanent magnet homopolarity to contacting side by side respectively side by side on a magnetic stripe fixed head 5; The magnetic pole same sex of each adjacent two permanent magnetic strip is sidelong relatively side by side and is connected into combination magnetic group; Upwards lead to a magnetic conductive board 7 respectively between each bar S level or N level composite poles and the magnetic sheet combination; Above the magnetic stripe fixed head, leave a magnetic separation path 10; Correspondingly with each magnetic conductive board above the magnetic separation passage be provided with magnet fixed head 1 on many; Magnet fixed head bottom is fixed with one respectively by polylith permanent magnet homopolarity magnetic stripe 3 in the combination that is arranged on each, and the pole orientation of magnetic stripe is opposite with corresponding magnetic conductive board magnetic pole on each, and the periphery of magnetic stripe has sealed one deck barricade 2 respectively on each; Magnet fixed head end face is separately installed with lift adjustment screw 9 on each, can regulate magnetic field intensity.On each the bottom surface of magnetic stripe be respectively equipped with water-tight layer 4 and 8 above the magnetic stripe fixed head that assembles.This magnetic group structure can be installed on the ramp type permanent magnetism ore separators, and is as shown in Figure 3, also can be installed on the drum-type permanent magnetism ore separators, as shown in Figure 4.The installation of flat-plate type permanent-magnetic ore separators 11 is to be fixed near on the support 15 in the band bottom surface cavity on the conveyer belt 17 magnetic stripe fixed head 5 is parallel, and each is gone up the magnet fixed head and go up magnetic stripe and is installed in above the front upper place and the back lower place are provided with the magnetic separation passage of cleaning hose 12 the top middle part of the feed opening 13 aligning conveyer belts of ore pulp simultaneously; During ore dressing, ore pulp drops on above the conveyer belt middle part, and is up along direction of advance; Iron powder is organized high-gradient magnetic field one that magnet forms more and is inhaled one and put and move upward; After the cleaning hose flushing, fall into concentrate discharge gate 16 in front, slag is poured mine tailing discharge gate 14 downwards by water, because of the High-gradient Magnetic group structure of being somebody's turn to do is carried out the effect that ore dressing has magnetic separation and gravity treatment; The rate of recovery and concentrate grade all are improved largely; List can reach the ore dressing requirement with magnetic separation, does not produce pollution, and cost is low.The mounting means of drum-type permanent magnetism ore separators is basic identical; Just magnetic separation passage camber distributes; Magnetic stripe and fixed head thereof on installing many above cylinder 18 outer surfaces; Cylinder internal upper part space corresponding on magnetic stripe install and fix an arc magnetic stripe fixed head and permanent magnetic strip and magnetic conductive board, on the magnetic stripe fixed head that assembles, watertight composition can be installed.
