Description

Technical Field

[0001] The utility model relates to the technical field of magnetic material processing, in particular to a screening device for magnetic material processing. Background Art

[0002] Materials that can respond to magnetic fields in some way are called magnetic materials. According to the strength of the magnetism exhibited by the material in the external magnetic field, it can be divided into diamagnetic materials, paramagnetic materials, ferromagnetic materials, antiferromagnetic materials and ferrimagnetic materials. Most materials are diamagnetic or paramagnetic, and they react weakly to the external magnetic field. Ferromagnetic materials and ferrimagnetic materials are strong magnetic materials, and the magnetic materials usually referred to are strong magnetic materials. For magnetic materials, magnetization curves and hysteresis loops are characteristic curves that reflect their basic magnetic properties. Ferromagnetic materials are generally Fe, Co, Ni elements and their alloys, rare earth elements and their alloys, and some Mn compounds. Magnetic materials are generally divided into soft magnetic materials and hard magnetic materials according to the difficulty of their magnetization.

[0003] For example, Chinese patent: CN219943635U, the technical solution disclosed in the patent is as follows: a screening device for magnetic material processing is disclosed, including a screening box, telescopic rods are fixedly installed around the bottom end of the screening box, a bottom plate is fixedly installed at the bottom end of the telescopic rod, a vibration structure for driving the screening box to move up and down is arranged between the screening box and the bottom plate, a screening plate is arranged inside the screening box, and a limiting structure for fixing the position of the screening plate is arranged on the inner side wall of the screening box. By setting the limiting structure, the screening plates with different sieve hole diameters can be effectively and quickly replaced according to needs, further improving the screening effect and improving the screening quality. The staff aligns the positioning hole on the screening plate with the positioning rod on the fixed frame and inserts it, and then pushes the fixed screening plate and the positioning rod into the two control panels. The staff pours the magnetic material to be screened from the feed inlet, and the magnetic material falls onto the screening plate. Due to the vibration of the screening box, the magnetic material on the screening plate begins to be screened.

[0004] However, in actual use, the above patent further improves the screening effect by replacing the screening plates with different sieve hole diameters, so a variety of different sieve plates are required, which easily causes waste and slows down the replacement. Utility Model Content
