Abstract

A magnetic field extrusion type open-ended magnetic system permanent magnet device consists of an angle plane open-ended magnetic system and an auxiliary pole magnet steel group. The auxiliary pole magnet steel group is lapped at the end part of the open-ended end of the main pole magnet steel group of the angle plane open-ended magnetic system according to the homopolarity level, to form the magnetic field extrusion of same polarity and the distortion of the line of magnetic force, thereby making the magnetic field intensity at the farther position of the large air clearance of the pole face of the main magnetic pole improved remarkably. The magnetic field extrusion type open-ended magnetic system permanent magnet device is applied to the aspects such as magnetic separation, magnetic stirring and magnetic tool, etc. which need the magnetic force.

Description

Magnetic-field extrusion formula opening magnetic system permanent magnetic device
Affiliated technical field
The utility model relates to a kind of magnetic-field extrusion formula opening magnetic system permanent magnetic device.The metallurgy, the machine industry that are used for magnetic separation and magnetic agitation operation.
Background technology
Traditional air gaps permanent magnetic device is open magnetic architecture, and two groups of the N utmost points, the opposite polarity magnet steel groups of S connect an end by the plane yoke, forms the magnet short-cut path closure; The other end of two groups of magnet steel forms the open circuit air gaps magnetic field of the N utmost point, two magnetic poles of the S utmost point, its shortcoming:
1 opening magnetic system leakage field is very big, and magnetic efficiency is low.
Magnetic field intensity is low at a distance for the 2 N utmost points apart from main pole, the S utmost point.
Summary of the invention
The utility model is to adopt in angle planar open formula permanent magnetic system less than 180 degree plane iron yoke angle boards with one, is equivalent to strengthen the distance of opening magnetic system one end two magnetic poles, and the magnetic line of force is moved outward; The 2nd, insert in the main pole open end with main pole direction and approximately become 90 degree, and the N utmost point, another auxiliary magnet steel group that S utmost point pole orientation is identical with it, form extruding, the repulsive interaction of the magnetic poles line of force in the same way, make the extremely original magnetic line of force of the N utmost point, S of main pole distinguish expansion deformation laterally, strengthened the intensity that the magnetic line of force is upwards walked, make the very big air gap of the N utmost point, the S of main pole at a distance the magnetic flux density at position strengthened.

Embodiment
Fig. 1 is a magnetic-field extrusion formula opening magnetic system permanent magnetic device structural representation.Its critical piece is angle planar open formula permanent magnetic system and auxiliary magnet steel group in the diagram.The main pole magnet steel group N utmost point 2 in the angle planar open formula permanent magnetic system is close to plane two angle faces of iron yoke angle board respectively with the main pole magnet steel group S utmost point 8, forms in the N utmost point, the S utmost point one end closed; The other end forms the open magnetic circuit of air gaps.The auxiliary magnetic pole magnet steel group N utmost point 3 links at the position by magnetic conduction angle board 4 therebetween with the auxiliary magnetic pole magnet steel group S utmost point 7, and the N utmost point at its two ends and the S utmost point are close to the N utmost point of main pole magnet steel group, the position, same polarity upper end of S utmost point open end respectively.Auxiliary magnetic pole magnet steel group is placed on above the aluminium supporting base 6, by brass screw 5 magnetic conduction angle board 4, aluminium supporting base 6 and plane iron yoke angle board 1 is tightened together.
Fig. 2 is magnetic line of force extruding strengthening principle figure.In the diagram in the angle planar open formula permanent magnetic system magnetic line of force of two groups of N utmost points, the extremely opposite polarity main pole magnet steel of S group open end be subjected to being about the line of force of the magnetic poles in the same way Φ of 90 degree directions from the N utmost point, S utmost point auxiliary magnetic pole magnet steel group FExtruding, make the very big air gap of the N utmost point, the S of the main pole magnet steel group magnetic line of force Φ at position at a distance MStrengthened, promptly magnetic flux density improves.
