The utility model is characterized in that a plurality of isosceles trapezoid magnets are arranged radially and closely on a supporter, to form a ring-shaped alternating N-S pole multi-pole magnetic system; the magnetization direction of each permanent magnet is adjusted at any angles; the included angle between the magnetization directions of two adjacent magnets is alpha; the pole number (n) is not limited, ranging from two to tens of poles. The intensity, gradient and action depth of the magnetic field on the drum surface of the device is adjusted by selecting the proper pole number (n).
Description
One, technical field
The utility model relates to a kind of permanent magnet device of drum magnetic separator, is used for the permanent magnetism application technology specifically, belongs to magnetic Circuit Design.
Two, background technology
The magnetic of traditional permanent-magnet drum type magnetic separator system piles up with the lower ferrite rectangle magnetic of energy product radially to be arranged in several N that separate, S alternation magnetic system on ferromagnetic yoke plate, a kind of " the Nd-Fe-B permanent magnet formula magnetic system that is used for magnetic separator " disclosed as Chinese patent (CN1063625A), be characterized in: the polarity of adjacent main magnet is opposite, the direction of magnetization of auxiliary magnet is vertical mutually with the direction of magnetization of main magnet, the permanent magnet magnetic system of this kind structure, magnetic field is low, greatly about about 1600 Ao Tesi, low along the radial direction gradient, gradient height along the circumferential direction.Number of poles is few.Iron ore character in all parts of the country is different, the specific susceptibility difference, therefore, the magnetic separator magnetic characteristic that they need is different, but the magnetic separator that China produces, magnetic characteristic is the same, for this reason, ore dressing will reach certain sorting index, and the technical staff will do complicated ore-dressing technique round this simple equipment.Ru Sidao, five roads even the choosing of six roads.
Three, technology contents
The purpose of this utility model is to provide a kind of table magnetic field strong, gradient height, the permanent magnet device of a kind of drum magnetic separator that tangential gradient is little.
The purpose of this utility model realizes in the following manner:
A kind of permanent magnet device of drum magnetic separator, include bearing support, permanent magnet, it is characterized in that: bearing support is provided with the trapezoidal permanent magnet of polylith, permanent magnet radially closely is arranged in the N of an annular, many magnetic level magnetic system of S alternation, the magnetization of every permanent magnet can be by arbitrarily angled rotation change, whenever faces two permanent magnet magnetization directions mutually and differs certain angle α, and permanent magnet is arranged in many magnetic poles system, number of poles n is unrestricted, can be by 2 utmost points to tens of utmost points.
Whenever, face angle that two magnet direction of magnetizations differ mutually and can be 0 °＜α≤90 °.
Permanent magnet is for waist is trapezoidal by the time.
Bearing support is garden cylindricality or half garden cylindricality.
But the bearing support nonferromagnetic.
But permanent magnet rare earth permanent magnet, ferrite etc. are permanent magnet arbitrarily.
The magnetic of permanent magnet is that length can be by 100mm-3500mm; Magnetic is that radius can be by 50mm-1500mm; Magnetic is that cornerite can be by 100 °-360 °.
Taper is decided by the radius of curvature of magnetic system.
The utility model magnet apparatus is radially closely to be arranged in the N of an annular, many magnetic level magnetic system of S alternation with polylith isosceles trapezoid magnetic patch on non-ferromagnetic bearing support, its tube table magnetic field intensity is the 500-7500 oersted, so can select the magnetic field intensity of magnetic separator according to the ratio number of magnetic poles of ore.Present inventor's number of magnetic poles is many, rises to 8 grades, 10 grades or more.
Four, description of drawings
Accompanying drawing is a structural representation of the present utility model
Five, embodiment
Embodiment 1:
The utility model is made up of bearing support 1 and permanent magnet 2, be fixed with bearing support 1 on the axle of magnetic separator, radially closely be arranged in the many magnetic poles system of N, the S alternation of an annular on the bearing support 1 with 6666 isosceles trapezoid permanent magnets 2, bearing support 1 is a cylindrical shape, cornerite is by 100 °-360 °, because the magnetic line of force of magnetic system all is concentrated in the tube table working space, and inner leakage field is very little, so bearing support 1 right and wrong are ferromagnetic, it is fixed on the axle of magnetic separator, the length direction unanimity of magnetic system, magnetic is that length range is by 100mm-3500mm; The radius of curvature R of magnetic system can be by 50mm-1500mm.The used magnet of magnetic separator is that all permanent magnets such as rare earth permanent magnet, ferrite all can.The direction of magnetization of adjacent two magnets differs certain angle α, α=45 °, and every magnet all is an isosceles trapezoid, taper is decided by the radius of curvature of magnetic system.
The magnetic characteristic of magnetic separator can realize that tube table magnetic field intensity increases with the increase of number of magnetic poles n by changing magnetic patch or number of magnetic poles n; Gradient increases with the increase of n.Therefore, radial magnetic field intensity reduces rapidly with the increase of n.So the depth of interaction in the magnetic field intensity of tube table, field gradients, magnetic field can be regulated by selecting suitable n.
