Embodiment
As shown in Figure 1, permanent magnet device for ultra-high field intensity cobber of the present invention is fixed with many groups by the radially alternate magnetic system that closely rearranges with isosceles trapezoid permanent magnet 4 of isosceles triangle magnetic conductor 3 on the half-cylindrical nonferromagnetic liner plate 2 that bracing frame 1 supports.The isosceles angle of long base of isosceles trapezoid permanent magnet and isosceles triangle magnetic conductor is adjacent in the magnetic system, the isosceles trapezoid permanent magnet is magnetized along the base direction, two permanent magnet same polarities of adjacent arrangement are arranged relatively, promptly the S utmost point of two magnets is extremely relative with S, or the N utmost point is extremely relative with N (as shown in the figure, the direction of arrow is the direction of magnetization of permanent magnet), the many magnetic poles that so just form N, S alternation on the base of equilateral triangle magnetic conductor are.
In this magnetic system, the proportionate relationship that relative dimensions satisfies is as follows: the proportionate relationship between the height c of the short base a of isosceles trapezoid permanent magnet, the base b of isosceles triangle magnetic conductor, isosceles triangle magnetic conductor is: b: a≤2; C: b 〉=1.5.
Because the magnetic line of force of this magnetic system all is concentrated in many magnetic poles alternating magnetic field of being made up of isosceles triangle magnetic conductor magnetic pole, therefore inner leakage field seldom, can form the magnetic field intensity up to 10000-15000 Gauss at the working surface of cylindrical shell.Because magnetic system is made up of many groups magnetic conductor and permanent magnet, magnetic is that cornerite can reach 100 °-360 °, and magnetic is that length range can reach 200mm-3500mm, and magnetic is that radius can reach 100mm-1500mm.
Embodiment: at radius is that isosceles triangle magnetic conductor sectional dimension is base 51mm on the half-cylindrical nonferromagnetic liner plate of 300mm, high 95mm, and material adopts electrical pure iron.The sectional dimension of isosceles trapezoid permanent magnet is long base 62mm, short base 30mm, and height is 95mm.The magnetic cording of Zu Chenging has disk pack angle and 12 N, S of 130 ° to hand over general magnetic pole thus, forms the magnetic field intensity of 13000Gs on the drum magnetic separator surface of diameter 800mm, can be used for the sorting of weakly magnetic minerals such as pyrite or manganese ore.
