Description

Centrifugal magnetic separator

Technical field

The utility model relates to a kind of material sorting device, exactly, is a kind of magnetic separator that magnetisable material is separated from material.

Background technology

Magnetic separator is widely used in the material sorting of industries such as abrasive material, refractory material, grain, feed, chemical industry.The horizontal drum-type structure of the general employing of present existing magnetic separator, according to the different requirements of selected material, the quantity of cylinder can have a plurality of, makes equipment volume huge, and structure is complicated.The subject matter that existing equipment exists is that the material ratio of sorting and cleaning after the magnetic separation is low, iron content in the material＞5 ‰; And carry raw material in the iron substance of selecting in a large number secretly, especially micro mist material, as carrying material quantity in 75 microns iron substances of selecting with thin material secretly is that to carry material quantity secretly in 70%, 53 micron iron substance of selecting with thin material be 90%, causes the waste of raw material and yield rate low.Patent 96220250.9 discloses a kind of " powder material induction type magnetic separation machine ", and this machine has been set up vibrating device on the cylinder of former magnetic separator, carry the many problems of raw material in the iron substance of selecting with solution secretly, but effect is unsatisfactory.In addition, for the demanding industry of ratio of sorting and cleaning, processing as industry powder materials such as building materials, pottery, abrasive materials, in order to reach quality standards, need adopt the method for pickling to remove residual iron substance in the material toward contact, generally all need oven dry just can carry out magnetic separation after the pickling, so both increased processing cost, its emission has increased the pollution to environment again.

Summary of the invention

The purpose of this utility model provides a kind of ratio of sorting and cleaning height to material, selects and carry raw material magnetic separator few, simple in structure in the iron substance secretly.

For reaching above-mentioned purpose, the technical solution adopted in the utility model is: centrifugal magnetic separator comprises motor, decelerator, swing roller, frame and is contained in cage and shell on the frame, motor is affixed by decelerator and driving shaft and swing roller, circumferential surface at swing roller, be fixed with one deck permanent-magnet material, cage is contained between swing roller and the shell, with the corresponding position of swing roller, the top of shell is provided with charging aperture, and the bottom of shell is provided with tapping hole and discharging opening; Swing roller is the awl tube of vertically installing, and cage is corresponding with the shape of rotation awl tube.

Fixing permanent-magnet material is orderly spaced permanent magnet on the rotation awl tube conical surface.

The arrangement mode of permanent magnet is the spirality consistent with drive shaft rotation direction.

The arrangement mode of permanent magnet is the horizontal-type of arranging around awl tube central horizontal.

At the outer surface of cage, be provided with the buting iron plate, the position of tapping hole is corresponding with the buting iron plate.

Above the rotation awl tube in charging aperture, be provided with fluid dividing cover, the diameter of fluid dividing cover is corresponding with the outside diameter circle of rotation awl tube.

Because adopted the rotation awl tube of vertical band tapering in technique scheme, material is gone up the absorption of multilayer magnetic pole, is stirred through boring tube, makes the material and the iron substance natural separation of being carried secretly, carries the few purpose of raw material in ratio of sorting and cleaning height, the cull secretly thereby reach.After adopting such scheme, the iron content in the material of choosing back is less than 1 ‰; Carry raw material secretly less than 3% in the iron substance of selecting,, reduced cost, also reduced pollution environment because the ratio of sorting and cleaning height has saved acid cleaning process.The power consumption of this magnetic separator is 1/10th of contrast type, can improve work efficiency more than 4 times simultaneously.This magnetic separator can also carry out normal sorting to wet, damp material.

The specific embodiment

Centrifugal magnetic separator comprises motor 1, rotation awl tube 2, frame 10 and is contained in cage 6 and shell 5 on the frame.Motor 1 is connected as a single entity with decelerator, and the output of decelerator is a driving shaft 2, and rotation awl tube 7 is fixed on the driving shaft 2.On the conical surface of rotation awl tube 7, be stained with one deck permanent-magnet material.Cage 6 is contained between rotation awl tube 7 and the shell 5, the shape of cage 6 is corresponding with the shape of rotation awl tube 7, in order to reduce the loss of magnetic force, cage 6 not with the contacted situation of magnetic material under, should try one's best near rotation awl tube 7, in the present embodiment, cage 6 is 0.5～5 millimeter with the spacing of magnetic material.Driving shaft 2 is supported by cage by the bearing at cage 6 two ends.Boring tube 7 corresponding positions with rotation, the top of shell 5 is charging apertures 3, and the bottom of shell 5 is provided with tapping hole 11 and discharging opening 12.

The permanent-magnet material that is bonded on the rotation awl tube 7 is orderly spaced permanent magnet 8, and its whole arrangement mode is and the consistent spirality of driving shaft 2 direction of rotation, also can be the horizontal-type of arranging around awl tube central horizontal.During arrangement, magnet arrangement mode each other be N extremely to the N utmost point, S is extremely to the S utmost point, in the present embodiment, piece and piece be spaced apart 0.5～5 millimeter, spacing is more little, magnetic force is big more; Between-line spacing is a bit larger tham the block gap, is beneficial to material.

The outer surface of cage 6, be provided with buting iron plate 9, in the present embodiment, buting iron plate 6 is and the consistent helical form of driving shaft 2 direction of rotation, also can be vertical shape, a side of buting iron plate be fixed on the outer surface of cage, and the opposite side of buting iron plate lifts, the outer surface shape that makes the plane of buting iron plate and cage makes the buting iron plate can play the effect that stops iron powder in an angle.Cage 6 and buting iron plate 9 are to be made by stainless sheet steel.The position of tapping hole 11 is corresponding with the position of buting iron plate 9.

In charging aperture 3, rotation awl tube top is provided with fluid dividing cover 4, and the diameter of fluid dividing cover 4 is corresponding with the outside diameter circle of rotation awl tube 7, and in the present embodiment, fluid dividing cover is fixed on the driving shaft 2, also can be fixed on the shell 5.The effect of fluid dividing cover 4 is that material is evenly distributed along circumference, also can block the top of cage 6 or rotation awl tube 7 simultaneously.

Its course of work is: motor 1 drives 7 rotations of awl tube by driving shaft 2.Material is sent into by charging aperture 3, be evenly distributed on cage 6 tops through fluid dividing cover 4, through the tapering Surface field, the free landing of the conical surface along cage, in the landing process, the magnetisable material of iron content is constantly by atwirl magnetic pole absorption of multilayer and disengaging, frequently stirring of producing from top to bottom separates totally the material of carrying secretly in the iron substance gradually, when the iron compound of selecting is brought to buting iron plate place, fall into tapping hole 11 owing to having broken away from magnetic field, material then is pooled to discharging opening 12 discharges from outer casing bottom after the choosing of free landing.
