Problems solved by technology

[0003] The inoculant is an additive that can promote the formation of graphite, reduce the tendency of whitening, improve the morphology and distribution of graphite, increase the number of eutectic groups, and refine the matrix structure. It is currently the most widely used 75 ferrosilicon inoculant; in the casting process , the molten iron in the ladle has a high temperature of about 1400 degrees Celsius. If there is powder in the inoculant, it will be oxidized and burned on the surface during the process of adding molten iron, and the inoculation effect cannot be achieved. Usually, the inoculant products are all particles with a particle size of 0.2mm or more. The particle size below 0.2mm is the dust loss. The more dust is generated, the greater the loss and the higher the cost. In the traditional inoculant production process, there will inevitably be powder, which is mainly transported and screened manually in the later stage of screening and bagging. The production efficiency is very low. During the transfer of inoculant particles, the scattered inoculant particles are often not well recycled. It will take a certain amount of time to manually collect them.

Description

technical field [0001] The invention relates to the field of inoculant production, in particular to an inoculant granule screening device. Background technique [0002] Cast iron is basically a eutectic alloy composed of iron, carbon and silicon, of which carbon mainly exists in the form of graphite; to produce high-quality castings, it is crucial to control the morphology of graphite formed when cast iron solidifies and the matrix metal structure ;Inoculation treatment is one of the most important links in the production process; a good inoculation treatment can make the cast iron have a microstructure that meets the requirements, thereby ensuring the mechanical properties and processing properties of the casting; adding an inoculant to the liquid cast iron can form a large amount of The submicroscopic core promotes the formation of eutectic clusters in the liquid phase; when the eutectic solidification temperature is close to the eutectic solidification temperature, fine g...
