Permanent-magnetic iron expeller magnetic patch combining structure
Technical field
The utility model relates to a kind of permanent-magnetic iron expeller, specifically a kind of permanent-magnetic iron expeller magnetic patch combining structure.
Background technology
Tramp iron separator mostly adopts electromagnet or rare earth permanent magnet to produce strong magnetic field and removes the ferromagnetic material in non magnetic bulk material, because magnetic patch structure in existing permanent-magnetic iron expeller arranges unreasonablely, have that magnetic field intensity is strong not, magnetic field range is little, the defect of magnetic penetrating force depth as shallow.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of when can produce enough strong magnetic field, can effectively expand the scope in magnetic field and the degree of depth of magnetic penetrating force again, and the permanent-magnetic iron expeller magnetic patch combining structure of not power consumption.
In order to solve the problems of the technologies described above, permanent-magnetic iron expeller magnetic patch combining structure of the present utility model, comprise a magnetic pole frame, the top of magnetic pole frame is provided with conductor top board, the bottom of magnetic pole frame is provided with without magnetic base plate, magnetic pole Kuang center arranges the strong magnetic part being combined by some rare earth permanent magnets, the pole orientation (the line direction of the S utmost point and the N utmost point) of strong magnetic part is positioned at vertical direction, the periphery of strong magnetic part is provided with magnetic part a little less than the transition being combined by some permanent-magnet ferrites, the pole orientation of the weak magnetic part of transition is identical with the pole orientation of strong magnetic part, the left and right sides of the weak magnetic part of described transition and front and back side arrange respectively the weak magnetic part that become by some ferrite combination, the pole orientation of weak magnetic part is positioned at horizontal direction.
On described conductor top board, be provided with conductor top board subplate.
The utility model has the advantage of:
Adopt the permanent-magnet ferrite of rare earth permanent magnet and same pole direction (being the line direction of the S utmost point and the N utmost point) to combine, combine with the ferrite of different magnetic poles direction (being the line direction of the S utmost point and the N utmost point) on four limits again, and magnetic pole frame, magnetic conduction top board by magnetic screen and assemble without magnetic base plate, utilized the combination of rare earth permanent magnet and permanent-magnet ferrite, when having produced enough strong magnetic field, effectively expanded again the scope in magnetic field and the degree of depth of magnetic penetrating force, and not power consumption.
