Description

The centrifugal magnetic separator of permanent magnetism bevel-type
Technical field
The utility model relates to a kind of mining machinery, particularly a kind of centrifugal magnetic separator of permanent magnetism bevel-type that iron ore and ore pulp are carried out sorting of being used for.
Background technology
The magnetic separator commonly used in iron ore selecting and purchasing field mostly is permanent-magnetic cylindrical formula magnetic separator.It is to drive cylinder by motor through reductor to rotate.During work, the ore particle that magnetic is stronger is to be attracted to cylinder surface under the effect of magnetic field force at magnetic, is mixed in weak magnetic in the magnetic mineral and non magnetic ore and is then got rid of and flow into tail-box and get rid of.The magnetic ore particle is taken out of field regions with the cylinder rotation, finishes assorting room thereby pour concentrate hopper with strong stream.
The a large amount of water of above-mentioned magnetic separator needs cleans and sweeps away the ore particle attached to the swing roller surface; Because the working face of sorting mineral is actual to be the part of the cylinder of swing roller, so the cylinder most surfaces does not all obtain utilization, thereby this type of magnetic separator volume is big, weight is big, efficient is low, and the waste water source.
Summary of the invention
Goal of the invention of the present utility model is in order to solve the weak point that above-mentioned traditional permanent-magnet drum type magnetic separator exists, and a kind of water saving, high efficiency, compact conformation, the centrifugal magnetic separator of permanent magnetism bevel-type that energy consumption is low are provided.
Realize the foregoing invention purpose by the following technical solutions: the centrifugal magnetic separator of a kind of permanent magnetism bevel-type, comprise frame, cylinder, be fixed on main shaft on the base, magnetic system, give ore deposit shower nozzle, tail-box, concentrate hopper, support shell, described cylinder is a pyramidal structure, is connected with main shaft with fixture; Described magnetic is is the circular platform type structure that is spliced by a plurality of permanent magnet blocks, is parallel to the awl tube outer surface, is fixed on to support on the shell.
Adopt technique scheme, compared with prior art, the utility model utilizes the sorting of the reciprocation realization of magnetic force, gravity and centrifugal force to concentrate and tailings.Because the rotating part of this machine is the taper core structure, has advantage in light weight, that effective area is big, can under higher rotation speed, move, the magnetic separator that drives than traditional reductor has reduced weight and has promoted operating efficiency.It is also advantageous in that significantly: its magnetic system is fixed on the casing not with the common rotation of awl tube, so it is that the attraction in magnetic field is stirred that ore particle constantly is subjected to magnetic at cone surface, making mine tailing composition in the ore pulp be cleaned current sweeps away, ore particle throws away the awl tube and is collected high efficiency by concentrate hopper under centrifugal action.

Fig. 2 is the awl barrel structure schematic diagram among Fig. 1.
Fig. 3 is to ore deposit nozzle structure schematic diagram.
Fig. 4 is that magnetic is the combining structure schematic diagram.
Among the figure, concentrate discharge pipe 1, mine tailing discharge pipe 2, main shaft 3, lower bearing 4, base 5, support that shell 6, upper bearing (metal) 7, drive pulley 8, tail-box 9, awl tube 10, magnetic are 11, concentrate hopper 12, clean jet pipe 13, throw away hole 15, set bolt 16 for ore deposit shower nozzle 14, mine tailing.
The specific embodiment:
Below in conjunction with accompanying drawing the utility model is further described.
Present embodiment is the centrifugal magnetic separator of a kind of described permanent magnetism bevel-type, by base 5, to support shell 6, main shaft 3, awl tube 10, magnetic be 11, form for ore deposit shower nozzle 14 etc.
See Fig. 1, Fig. 2, cylinder are the pyramidal structure cylinders, are called awl tube 10, and the antimagnetic corrosion resistant plate of these awl tube 10 usefulness is rolled into, and its inner surface is provided with the rubber wear-resisting layer.To between 90 degree, optimum angular is 60 degree to the drift angle angle of awl tube 10 at 45 degree, and its bottom is provided with the mine tailing of discharging for mine tailing and throws away hole 15, and this mine tailing throws away hole 15 evenly distributed formation ring-types.The bottom of awl tube 10 is securely fixed on the main shaft 3 with set bolt 16.Upper bearing (metal) 7, lower bearing 4 are sleeved on the main shaft 3 successively, and main shaft 3 is fixed on the base 5 through upper bearing (metal) 7 and lower bearing 4, and main shaft 3 is connected with drive pulley 8, obtain power from the outside by drive pulley 8.Drive pulley 8 drives main shaft 3 rotations under the driving of motor, awl tube 10 and main shaft 3 speed rotation together.
See Fig. 4, magnetic is 11 to be to be spliced by a plurality of permanent magnet blocks, and a plurality of permanent magnet blocks are arranged, closely arranged mutually and constitute the circular platform type structure with bonding or screw fixation method.The magnetic of circular platform type structure is 11 to be fixed on and to support on shell 6 inner surfaces, and close parallel is in the outer surface of awl tube 10, and is contactless with awl tube 10, do not rotate with main shaft 3.Concentrate hopper 12 is positioned at the top of awl tube 10, and concentrate discharge pipe 1 is communicated with concentrate hopper 12.The cleaning jet pipe 13 that the hydro-peening clear water is used inserts in the awl tube 10.Tail-box 9 is positioned at the below of awl tube 10, and mine tailing discharge pipe 2 is communicated with tail-box 9.
As Fig. 3, Fig. 1, giving ore deposit shower nozzle 14 is inverse-T-shaped structure, inserts in the awl tube 10, the solid-liquid mixing ore pulp of giving 14 ejections of ore deposit shower nozzle of "T"-shaped structure is umbrella shape, falls into the bottom in the awl tube 10 equably.
Operation principle of the present utility model:
The bottom of solid-liquid mixing ore pulp through spraying into awl tube 10 for ore deposit shower nozzle 14, clash into awl tube 10 ore pulp ejection back, and this position just is positioned at the field regions bottom.Wherein the ore particle that magnetic is stronger is to be attracted under the magnetic field force effect on the inner surface of awl tube 10 at magnetic, and weak magnetic that contains in the ore pulp and namagnetic substance are then swept away under the effect of cleaning jet pipe 13 to be thrown away hole 15 through mine tailing and throw away; Collect by mine tailing discharge pipe 2 through tail-box 9 again and discharge machine.
By magnetic is 11 to be adsorbed on the high speed rotation of the ore particles of awl tube 10 inner surfaces along with awl tube 10, at gravity, moves upward gradually along awl tube 10 inwalls under the acting in conjunction of magnetic force and centrifugal force; And in this process, constantly be subjected to cleaning the cleaning of the current of jet pipe 13 ejections, increase along with the radius of turn of the awl tube 10 that makes progress, centrifugal force is increasing, the centrifugal force that rear conical-tube 10 rotations produce surpasses gravity and the magnetic force that ore particle is subjected to, ore particle is thrown out of awl tube 10, collected by concentrate discharge pipe 1 by concentrate hopper 12 and to discharge outside the body, thereby finish the assorting room of whole ore pulp.
