Problems solved by technology
[0004] However, magnetic powder is easy to agglomerate and accumulate, which makes it difficult to achieve efficient drying by conventional heating methods, such as common hot air drying. The heating efficiency is low, and the magnetic powder inside and outside has a high humidity difference

The invention discloses a magnetic powder high-dispersity dynamic drying device, and belongs to the technical field of magnetic powder drying. After magnetic powder is dispersed and adsorbed through a water absorption column, hot air input by a hot air pipe is used for drying the magnetic powder, meanwhile, a heating roller can rotate, and in the normal state, when the water absorption column adsorbs the magnetic powder, the magnetic powder is dried through the hot air pipe. And in the rotating process, the magnetic powder continuously migrates to the powder collecting ball and is closer to the hot air pipe, the hot air drying effect is improved, meanwhile, the water absorbed by the water absorption column is heated and evaporated, and therefore the water absorption capacity of the water absorption column is recovered. And the positions and postures of the magnetic powder are changed in the dynamic migration process, so that the contact effect between hot air and the magnetic powder is effectively improved, drying dead angles are not prone to occurring, and compared with the prior art, the magnetic powder drying efficiency and effect can be obviously improved.
Description
technical field [0001] The invention relates to the technical field of magnetic powder drying, in particular to a dynamic drying device with high dispersion of magnetic powder. Background technique [0002] Neodymium magnets, also known as NdFeB magnets, are tetragonal crystals formed of neodymium, iron, and boron. The magnetic energy product of this magnet is greater than that of samarium-cobalt magnets. The magnets are now permanent magnets second only to absolute zero holmium magnets. It is also the most commonly used rare earth magnet. NdFeB magnets are widely used in electronic products, such as hard drives, mobile phones, earphones, and battery-powered tools. [0003] NdFeB magnets are prone to moisture during production and processing, and NdFeB magnets are prone to oxidation after being wet, which reduces product quality. Therefore, they need to be dried before being processed into finished products. [0004] However, magnetic powder is easy to agglomerate and accu...
