Abstract
A permanent-magnet with sector whose magnetic wrap angle is alpha for high-intensity magnetic separator is disclosed. The magnetic flux-concentrating permanent magnet consists of a main magnetic block, an auxiliary magnetic block, a flux-concentrating block, a magnetizer and a non-magnetizer, and is characterized in that the magnetization direction of the main magnetic block (1) is axial, and the magnetization direction of the auxiliary magnetic block (2) is radial. In the axial direction, the width of the main magnetic block is greater than or equal to four times of the width of the auxiliary magnetic block, and the widths of the magnetic gathering block and the auxiliary magnetic block in the axial direction are equal. Two adjacent main magnetic blocks, auxiliary magnetic blocks and magnetic gathering blocks are extruded together along the axial direction to form a magnetic pole, so that a plurality of magnetic poles are extruded together alternately along the axial direction to form a magnet, and a magnetic field with the polarity changing alternately along the axial direction is generated on the outer arc surface of the magnet.
Description
The present invention relates to a kind of permanent magnetic separator magnet that is applied to the sorting and the purification of metal and non-metallic material.
Utilize Nd-Fe-Bo permanent magnet material to develop the work field intensity in recent years both at home and abroad and reach the above roller belt-type strong permanent-magnet separator of 1T.But because problems such as wearing and tearing, belt deviation and belt clamp ore deposits, on industrial production, particularly iron ore beneficiation can't be used.
In 5,636 of 94238402.4 and the U.S. that my institute is arranged aspect the cylindrical permanent magnetic separation machine, 748.Jun.10,1,997 two patents, but all be not suitable for sorting of coarse grain weak magnetic mineral, mainly there are three problems; 1. the polarity in magnetic field is that traditional circumferencial direction along cylinder alternately changes; 2. main magnetic patch 1 is not having face to contact the degree of depth with a pair magnetic patch 2 in the radial direction, makes two main magnetic patch 1 by poly-magnetic patch 3 like this, and the high-intensity magnetic field that pushes on poly-magnetic patch 3 intrados demagnetizes pair magnetic patch; 3. the fixed form of magnet existing problems cause magnetic field to can not get effective utilization.
What the object of the present invention is to provide that a kind of magnetic polarity alternately changes vertically not only is adapted to iron ore beneficiation, also is adapted to the cylinder type magnetic separator magnet of nonmetal deironing.
To achieve these goals, technical scheme of the present invention is: magnet is when being used for the cylinder type magnetic separator, and its cornerite is the segment of α, is made up of main magnetic patch 1, pair magnetic patch 2, poly-magnetic patch 3, magnetic conductor 4 and non-magnetizer 5.To be axial fan-shaped main magnetic patch and direction of magnetization be radially fan-shaped pair of magnetic patch for two direction of magnetizations, a poly-magnetic patch and a non-magnetizer that is processed into magnetic conduction woods material is formed a magnetic pole, a plurality of such magnetic poles order vertically are arranged on the extrados of magnetic conductor, and the polarity of magnet on extrados is alternately changed vertically.Be described further below in conjunction with accompanying drawing 1,2 and 3:
Fig. 1 is the magnet front view, and Fig. 2 is the magnet side view, and Fig. 3 is main magnetic patch 1 to contact the degree of depth in warp direction be 1/2 front view with paying magnetic patch 2.
Form by main magnetic patch 1, pair magnetic patch 2, poly-magnetic 3, magnetic conductor 4 and non-magnetizer 5 among the figure.The direction of magnetization of two adjacent main magnetic patch 1 is opposite mutually vertically, and the direction of magnetization of pair magnetic patch 2 is radially gathered magnetic patch 3 and is pressed on the outer lonely face of paying magnetic patch 2, constitutes a magnetic group, and poly-magnetic patch 3 is screwed on magnetic conductor 4.Main magnetic patch 1 has groove on two sectors vertical with self direction of magnetization, with two sectors of the poly-magnetic patch 3 on the contacted both sides of main magnetic patch on correspondingly be processed into a corresponding muscle, it is inlayed together mutually.
As shown in Figure 3, main magnetic patch 1 with pay magnetic patch 2 and equal to pay 1/2 of magnetic patch 2 radial thickness in the radial direction the degree of depth that contacts.Because the magnetic anisotropy of permanent-magnet material makes the magnetic field intensity surge of paying on magnetic patch 2 extrados.Like this by two extruding of main magnetic patch, make and pay that magnetic field reaches very high on the outer lonely face of magnetic patch.Thereby can resist on poly-magnetic patch 3 intrados and push the demagnetization that the magnetic field of coming out tackles magnetic patch 2.Therefore, adjacent two main magnetic patch 1, pair magnetic patch 2 and poly-magnetic patch 3 are formed a magnetic pole.A plurality of like this magnetic poles alternately press together vertically and form a magnet, the magnetic field that polarization alternately changes vertically on the magnet extrados.Through the sectorial magnetic field district time, owing to form magnet short-cut path between material particles and adjacent two magnetic poles, thus increased magnetic force.
Claims (2)
1. a magnetic separator magnet that is suitable for metal and nonmetallic mineral sorting and purification is made up of main magnetic patch (1), pair magnetic patch (2), poly-magnetic patch (3), magnetic conductor (4) and non-magnetizer (5).It is characterized in that: adjacent two fan-shaped main magnetic patch (1), one fan-shaped pair magnetic patch (2) and a poly-magnetic patch (3) that is processed into permeability magnetic material press together vertically and form a magnetic pole, a plurality of like this magnetic poles alternately press together vertically and form a magnet, the magnetic field that polarization alternately changes vertically on the magnet extrados, and will gather magnetic patch (3) with screw and be fixed on the magnetic conductor (4).
