Description
The utility model is a kind of novel medium-high magnetic field permanent magnetic separator that is applied to the sorting and the purification of non-ferrous metal, ferrous metal and non-metallic material.
Utilize Nd-Fe-Bo permanent magnet material to develop cartridge type medium-high magnetic field permanent magnetic separator in recent years both at home and abroad, as: Humboldt, zviet (see: " industrial mineral " 1992.3) and Baotou Iron and Steel Company " mine technology " 1991.6) (see: department such as.Because the subject matter that this class magnetic separator exists is to form a poly-magnetic open circuit magnetic circuit with traditional open circuit magnetic circuit or with the club-shaped material of the different direction of magnetizations, so magnet surface magnetic field does not reach the remanent magnetism Br of material itself, the magnetic field intensity of drum surface also can't reach more than 0.8 tesla, and because bar-shaped magnet direction is oblique, internally inconsistent, such magnetic structure makes the machining difficulty, and waste of material is big, all is difficult to practical application at present at home; Another kind of roll-type permanent magnetic motor, though it has partly used the extruding magnetic circuit, magnet surface magnetic field intensity higher (1.2T).But the magnetic field gradient height, it is fast especially to leave the magnet surface field decay, and magnetic pole is that N-S axially alternately changes, and makes not only that to sort efficient low, and can only be used for dry-type separation, and right-200 order materials are also powerless.
The purpose of this utility model provides a kind of magnetic field intensity height, and sorting result is good, feed particle size wide ranges, the cartridge type high intensity magnetic separator of Wet-dry.
For achieving the above object, its technical scheme: magnetic wrap angle sigma segment profile as shown in Figure 2, in the fixing segment of not rotating of cylinder built-in with cylinder, segment disk pack angle is α, it is by skeleton (6), magnetic conductor (7), main magnetic patch (8), magnetic inductive block (9), paying magnetic patch (10) forms, paying magnetic patch (10) is adsorbed on the magnetic conductor (7) by self magnetic force, the little cambered surface of fan-shaped main magnetic patch (8) tightly presses together with the little cambered surface same polarity ground of paying magnetic patch (10) and forms closed magnetic circuit, to lead with magnetic inductive block (9) between the two main magnetic patch (8), paying the magnetic flux of magnetic patch generation all derives, and produces on the magnet external magnetic poles when cylinder rotates up to the high-intensity magnetic field in the circumferencial direction rotation more than the 1.6T; The upper and lower surface made from permeability magnetic material is that the magnetic conductor (7) of arc surface is the arc piece, equidistant N-S utmost point is alternately inhaled the radially pair magnetic patch (10) of the different direction of magnetizations of adhesion on the last cambered surface of magnetic conductor (7), paying magnetic patch (10) is that the bottom surface, ore deposit is the trapezoidal magnetic patch of cambered surface up and down, the lower camber side of paying magnetic patch (10) adheres to mutually with magnetic conductor (7), last cambered surface (being little cambered surface) gets magnetic patch (9) along paying adsorbing on magnetic patch (10) center line, magnetic inductive block (9) is that thickness is 5～13mm rectangular thin plate, rib with cylinder center's line parallel is respectively arranged on two wide of the thin plates, make the rib of magnetic inductive block (9) both sides go up corresponding groove formation stationary fit with adjacent main magnetic patch (8) respectively, main magnetic patch (8) is that upper and lower surface is an arc surface, the secter pat of one groove is respectively arranged in the middle of the two sides, and the direction of magnetization is a circumferencial direction; Magnetic wrap angle sigma segment both sides and vertically two ends be welded on the magnetic conductor (7) by non-magnetic conduction arc plate skeleton (6), make magnetic wrap angle sigma segment and skeleton become a rigid unitary, main magnetic patch (8), pair magnetic patch (10), magnetic conductor (7) cambered surface and cylinder concentric, the main magnetic patch of paying is all made with high performance Nd FeB permanent-magnet material.
Fig. 1 is the utility model housing construction schematic diagram, and accompanying drawing 2 is the profile of the utility model magnetic wrap angle sigma segment.
The drawing explanation of Fig. 1: the utility model mainly comprises: (1) mine feeding bucket, (2) running part, (3) cylindrical portions may, (4) magnet part, (5) ore discharge part.Below explanation respectively: (1) mine feeding bucket part: be equipped with steel plate on frame and weld ore bucket, ore bucket one side is equipped with geared sleeve and adjusting rod, and the turn adjusting rod can be regulated the openings of sizes of ore bucket gate continuously; (2) running part: motor is connected with decelerator with clutch, and flatly is contained on the frame, adorns the gear wheel engagement on a pinion and the cylinder right end cap on the reducer output shaft; (3) cylindrical portions may: cylinder is made with non-magnetic Stainless Steel, and two end cap is the casting lead material, in bearing and fan-shaped magnet be housed assemble; (4) magnet part: fan-shaped magnet two ends in the accompanying drawing 2 and axle sleeve welding are contained in axle sleeve on the magnet axis with screw rod; (5) ore discharge part: the essence made from steel plate, in, three buckets of mine tailing are contained in cylinder one side bottom respectively, between concentrate and the middle ore bucket and between middle ore bucket and the mine tailing bucket demarcation strip is being housed respectively, an end of separating is equipped with a handwheel, can regulate the demarcation strip inclination angle continuously.
Use step of the present utility model is: when motor start-up, decelerator is the fan-shaped magnet do running counterclockwise of α around the disk pack angle by the gear driven cylinder.The size that material in ore bucket is regulated opening by the mine feeding bucket flashboard makes material be distributed to branch constituency, magnetic field on the barrel surface equably.Because action of centrifugal force, non-magnetic material has enough chances loose and be pulled out away from barrel surface because of the branch constituency that acts on of rotating excitation field, and magnetic material is owing to rotated together by the effect of drum surface magnetic force and cylinder, when leaving the disk pack angle, be pulled out away from drum surface and be discharged into the concentrate mouth owing to losing magnetic force, in the ore bucket, non-magnetic material was discharged into the mine tailing mouth, thereby obtains sorting during middle magnetic thing (as intergrowth) was discharged into.
This machine carries out sorting to granularity for-2mm iron mineral, compares test with the jigging machine sorting, and when head grade was 31.3%, obtaining concentrate grade was 54.28%, and tailings grade is 1 6.11%, and the rate of recovery is 68.13%.And the concentrate of jigging machine sorting is 50.35%, and mine tailing is 22.43%, the rate of recovery only 41.03%.
Major advantage of the present utility model is: sorting magnetic field height, and sorting result is good, and (50mm), big, the power saving for the treatment of capacity, body are light for the feed particle size wide ranges.
