Description
Technical Field
[0001] The utility model belongs to the technical field of magnetic core manufacturing, in particular to a processing device for magnetic core iron powder. Background Art
[0002] A magnetic core refers to a sintered magnetic metal oxide composed of a mixture of various iron oxides. For example, manganese-zinc ferrite and nickel-zinc ferrite are typical magnetic core materials. Manganese-zinc ferrite has the characteristics of high magnetic permeability and high magnetic flux density, and has low loss characteristics at frequencies below 1MHz. Nickel-zinc ferrite has extremely high resistivity, low magnetic permeability of less than a few hundred, and also produces low losses at frequencies above 1MHz. In the field of electronic component production, magnetic cores are basic application components, and their ferrite cores are widely used in coils and transformers of various electronic devices, and the basic raw material for the production of magnetic cores is iron powder.
[0003] The production process of magnetic core mainly includes powder making, molding, sintering, grinding, cleaning and drying, finishing, etc. Among them, a variety of processing equipment is needed in the powder making process, such as crushers, screening machines, etc. The quality of iron oxide powder determines the key to the quality of the magnetic core after molding. Since there are many unqualified particles or impurities in the iron oxide powder, the qualified iron oxide powder needs to be screened out by the screening machine before production to ensure the production quality.
[0004] Most of the current screening machines vibrate and screen the magnetic core iron powder in the screening cylinder as a whole, and the area of the screen is fixed, but a large part of the magnetic core iron powder is inside the screening cylinder and is not easy to contact the screen, or part of the magnetic core iron powder in a vibrating state for a long time is always in the middle area and is not screened, resulting in low screening efficiency and insufficient screening; therefore, the utility model designs a processing equipment for magnetic core iron powder.
