Abstract

The utility model relates to a rare-earth permanent magnet iron remover, which is used for cleaning iron pieces mixed in raw material and the iron pieces is arranged on a belt conveyer. The utility model is characterized in that a magnet pole is formed by a magnetic steel sheet magnetic yoke and a rare-earth permanent magnet block; a magnetic pole face is provided with a pair of north and south magnetic poles; the north and the south magnetic poles are arranged on the same plane; the north pole is positioned on the center of the magnetic poles; the south pole is positioned on the circumference. The utility model has the advantages of simple structure, light weight, without power consumption, large magnetic flux density range, and strong magnetic permeable force.

Description

The rare earth permanent magnet tramp iron separator

The utility model relates to a kind of tramp iron separator.

At present, in industries such as metallurgy, coal, sugaring, papermaking, plastics, wine brewing, feed, food processings, mostly adopt the direct solenoid tramp iron separator to remove the ironware of sneaking in the raw material.The magnetic flux density of electric magnetic iron remover is big, good iron removal effect, but structure is huge, heavy, and power consumption is big.

The purpose of this utility model is to design a kind of in light weight, not power consumption, close big, the effective rare earth permanent magnet tramp iron separator of magnetic.

The technical solution of the utility model is: it has frame, unloads iron belt mechanism and magnetic pole, and its iron belt that unloads that unloads iron belt mechanism is turned round around magnetic pole by motor-driven, and magnetic pole is arranged on the central authorities of frame.Principal character is that magnetic pole is made of magnetic steel plate yoke and rare earth permanent magnet piece, and its magnetic pole strength only has a pair of magnetic pole of NS, and the NS utmost point coexists on the plane, and the N utmost point is positioned at magnetic pole central authorities, around the S utmost point is positioned at.

The utility model adopts the rare earth permanent magnet piece to do magnetic source, not power consumption; Simple in structure, in light weight; The NS utmost point coexists on the plane, and the track density scope that the space forms is big, and magnetic penetrating force is dark.

Below in conjunction with description of drawings most preferred embodiment of the present utility model.

As Fig. 1, shown in Figure 8, the utility model by frame 1, magnetic pole 2, unload iron belt 3 and form, unload iron belt and drive running around magnetic pole by the motor 4 that is arranged on the frame, when the raw material on the equipment of conveyer 7 is below magnetic pole, ironware in the raw material will be drawn onto and unload on the iron belt, throws to along with the running of unloading iron belt on one side.

As Fig. 2, shown in Figure 3, magnetic pole of the present utility model is made of square magnetic steel plate yoke 5 and rare earth permanent magnet piece 6, the rare earth permanent magnet piece is positioned at the yoke centre, its magnetic pole strength is a pair of NS magnetic pole, and the NS utmost point coexists on the horizontal plane, the N utmost point is positioned at magnetic pole central authorities, around the S utmost point is positioned at, leaves the space between NS the two poles of the earth.

As Fig. 4, shown in Figure 5, magnetic pole of the present utility model is made of square magnetic steel plate yoke and rare earth permanent magnet piece, yoke center and both sides are provided with the rare earth permanent magnet piece, its magnetic pole strength is a pair of NS magnetic pole, and the NS utmost point coexists on the horizontal plane, the N utmost point is positioned at magnetic pole central authorities, and the both sides distribution 1/2S utmost point of the N utmost point leaves the space between NS the two poles of the earth.

As Fig. 6, shown in Figure 7, magnetic pole of the present utility model is made of circular magnetic steel plate yoke and rare earth permanent magnet piece, in the centre of yoke the rare earth permanent magnet piece is set, its magnetic pole strength is a pair of NS magnetic pole, and the NS utmost point coexists on the horizontal plane, the N utmost point is positioned at magnetic pole central authorities, around the S utmost point is positioned at, leaves the space between NS the two poles of the earth.
