Description
Technical field
The present invention relates to a kind of dry-type magnetic extractor, belong to the Mineral Processing Engineering field, be particularly useful in the Dual-Phrase Distribution of Gas olid based on fluidised dry-type magnetic extractor.
Background technology
The dry-type magnetic extractor that is used for magnetic thing and nonmagnetics sorting at present has single magnetic separation roller, two magnetic separation roller and many magnetic separation rollers, and its structure all is employed in magnetic separation roller top feed along the circumferential direction, and charging gear uses revolving plow reclaimer or oscillating feeder.Using under the magnetic material quantity same case, these dry-type magnetic extractors are compared with wet magnetic separator, and treating capacity is little, and the magnetic thing loss in the mine tailing is big.Existing each magnetic separation roller only can be to going into to select materials magnetic separation once, and treating capacity can not be big, otherwise the magnetic thing amount of losing in the mine tailing can increase, though and the structure of a plurality of magnetic separation rollers can guarantee that the magnetic thing loss in the mine tailing is few, can cause equipment cost significantly to increase.Though revolving plow reclaimer can be controlled feeding coal, it belongs to pulsation feed form, and the feed uniformity is bad also can to cause the magnetic material content in the mine tailing to increase; Vibrating feed equipment not only takes up room greatly, adjusts the feeding coal difficulty and belongs to the outer support equipment of magnetic separator.Owing to below magnetic separation roller, have the highest efficiency of separation, so under last feed-type, the cornerite of magnetic system is big, it is many to consume magnetic material, and equipment cost is high.
Summary of the invention
Technical problem: the objective of the invention is to overcome the weak point in the prior art, provide a kind of compact conformation, feed evenly, the scalable feeding coal, take up room little, treating capacity is big, the high and low cost of the efficiency of separation based on fluidised dry-type magnetic extractor.
Technical scheme: of the present invention based on fluidised dry-type magnetic extractor; Comprise magnetic separation roller; Described magnetic separation roller is obliquely installed, and the below of magnetic separation roller is provided with the fluidisation sorting groove identical with its angle of inclination, and the front of magnetic separation roller is provided with the charging gear to the anterior pan feeding of fluidisation sorting groove; Described fluidisation sorting groove comprises pedestal, accompanies the arc air distribution plate of filter cloth in the middle of pedestal is provided with, and the front portion of pedestal is provided with the pan feeding guide groove that links to each other with the arc air distribution plate, and the pedestal bottom is provided with air chamber; Described charging gear comprises the wedge shape surge bunker, and the wedge mouth place of wedge shape surge bunker is provided with the feeding coal control panel by the control of amount control of sailing axle, and the bottom of wedge shape surge bunker is provided with the feed flashboard by the control of switch bearing pin.
The angle that described magnetic separation roller is obliquely installed is 3～10 °; Be provided with insertion air guide fluidisation bar wherein in the described wedge shape surge bunker; Described air guide fluidisation bar by wireway, be located at the filter disc in the wireway outlet and the open-work pressure cap that is fixed on the wireway constitutes.
Beneficial effect: the present invention combines magnetic separation and feed, control function, is specially adapted to the medium solid density automatic regulating system in the Dual-Phrase Distribution of Gas olid dry coal preparation system, also can be used as the actuating equipment in the relevant automatic control system.With selected medium solid fluidisation, make it have the quasi-fluid characteristic through fluidization technique, sorting material flows and magnetic separation once and again in the bottom of magnetic separation roller; Changed deficiency that magnetic separation roller can only carry out a sorting in the prior art, the magnetic thing loss in the magnetic tailing has significantly been reduced, under the requirement that guarantees the efficiency of separation; Not only can add high throughput; Also reduced the quantity of magnetic separation roller, because the branch favored area is limited to the bottom of magnetic separation roller, the cornerite that used magnetic is has only of the prior art 1/2 ~ 1/3; Saved the use amount of magnetic material, the cost of equipment is significantly reduced.Charging gear is expanded the feed width with fluidizing method and is had that power consumption is little, little advantage takes up room; Method with adjustment feed thickness is adjusted the pulsation feed state that feeding coal has been eliminated the impeller feeding method, has also avoided the vibrating feed mode need increase the problem that external equipment is supported.During flashboard feed switch, actuating quantity is few, acutely friction of nothing, can not produce blade wear after the long-term work and go into to select materials leakage problem.
