Abstract
The utility model relates to a wet magnetic separator, which is a set of rotating magnetic system positioned below the prior magnetic separator. The product is used to the medium (iron ore fines) recovery in coal water for coal washery. The prior product needs two sets of the magnetic separator operation, or else the cleaning effect is not ideal. Because of the prior product structure, i.e. the medium away from the magnetic system is not easy to be attracted, partial magnetic force is offset by the water flow velocity and a part of medium needs next separation, the prior equipment has the problems of large investment, large occupation area and troublesome separation process. The product with a set of rotating magnetic system can increase magnetic field intensity and the medium is not easy to leak out. In addition, the rotation direction of the rotating magnetic system is opposite with the water flow direction, and the medium moves opposite with the water flow direction and is easier to be attracted on a magnetic system cylinder, with compact equipment and occupation space saving.
Description
Technical field
The utility model belongs to the design and the manufacturing technology field of magnetic separator.
Background technology
The employed wet magnetic separator in the coal washery is that cylinder constitutes by sorting groove and magnetic at present.Magnetic is that magnetic system is housed in the cylinder.When equipment was worked, medium (Iron Ore Powder) entered the sorting groove by feed box in black water.At this moment, magnetic is that cylinder rotates in the direction of the clock, and magnetic system does not change in the tube, and medium is attracted to drum surface, is taken out of field regions along with the cylinder rotation, falls in the concentrate hopper, is recovered.But, make the medium of its unable recovery black water lower floor because open magnetic system is just big more away from the pole surface field decay more.The power of coal slime flow rate of water flow generation also can be taken away a part of medium, so recovering effect is bad in addition.Because the rate of recovery is not high, have to adopt the mode of two sections sortings, promptly establish two cover magnetic plants, after treating the preceding paragraph choosing, the black water that flows out by tail-box more again sorting once, but two equipment are the same, always have some media to run away away from magnetic field or under the effect of flow force.Thus, separating effect is undesirable.Two sections screening installations are set, and it is big to occur equipment investment again, and floor space is big, the disadvantage of sorting process complexity.
Summary of the invention
It is simple that the purpose of this utility model provides a kind of sorting process, good separation effect, and the wet magnetic separator that floor space is little is to overcome the existing disadvantage of existing product.Structure of the present utility model as shown in drawings; Constitute by sorting groove and magnetic system.This product briefly is to set up a cover revolving magnetic system in the bottom of existing product.Its concrete structure is: it is cylinder (6) that a magnetic is arranged on the top of sorting groove (3), has fixedly magnetic system (5) in cylinder.One feed box (1) is arranged in the left side of sorting groove.One concentrate hopper (2) is arranged in the bottom of feed box.One tail-box (4) is arranged on the right side of sorting groove.One revolving magnetic system (7) is arranged in the bottom of sorting groove.Revolving magnetic system is made up of one group or some groups of homopolarity magnets.Magnet is pressed branch settings such as circumference.Its utmost point to the magnetic pole utmost point of corresponding fixedly magnetic system to opposite, form N, S extremely to the utmost point.This product is fixed in ground with four pin of sorting groove when mounted.Magnetic is that portion of cylinder center has one.This is fixed on the pedestal that magnetic is the cylinder two ends.The central shaft of revolving magnetic system is fixed on the pedestal at revolving magnetic system two ends.The using method of this product is identical haply with existing product with method of work.Black water enters the sorting groove by feed box, and this moment, magnetic was that cylinder rotates (the interior magnetic of tube system does not rotate) in the direction of the clock, and the revolving magnetic system of sorting groove bottom is by rotation counterclockwise (being commonly called as single magnetic is rotation).Owing to set up revolving magnetic system in sorting groove bottom, increased magnetic field intensity.Medium in black water major part under magneticaction is attracted to drum surface, falls into concentrate hopper along with the cylinder rotating media breaks away from magnetic field.Medium in black water lower floor then is rotated magnetic system and holds.Because the direction of rotation of revolving magnetic system is opposite with water (flow) direction, makes medium enter tail-box under the effect of flow force, just makes medium obtain a power opposite with water (flow) direction, under the effect of this power, medium water (flow) direction motion dorsad.When revolving magnetic system rotates to pole gap and fixedly magnetic is relative, following magnetic field pop-off, making the easier magnetic that is adsorbed to of medium is drum surface, falls into concentrate hopper then and is selected.The utility model is simple in structure, and is reasonable in design, just sets up a cover revolving magnetic system on the existing product basis, can reach the effect that a sorting will reach.Promptly reduce equipment investment, reached the little purpose of floor space again.The effect of sorting also increases substantially.

The specific embodiment
The sorting groove of this product, magnetic are that cylinder can adopt metallic plate system, preferably adopt the corrosion resistant plate welding to make, and the magnet in the magnetic system can adopt general magnet or rare earth permanent magnet magnet.With reference to this specification and accompanying drawing, by the existing known technology of making magnetic separator, processing and manufacturing can be reproduced this product.
Claims (2)
1, a kind of wet magnetic separator is that cylinder (6) is formed by sorting groove (3) and magnetic, it is characterized in that a revolving magnetic system (7) is arranged at the bottom of sorting groove.
2, magnetic separator according to claim 1, it is characterized in that said revolving magnetic system (7) is made up of one group or some groups of homopolarity magnets, magnet is pressed branch settings such as circumference, its utmost point to the magnetic pole utmost point of corresponding fixedly magnetic system to opposite, form N, S extremely to the utmost point.
