Problems solved by technology
[0004] In order to overcome the existing technology, the steel slag is usually used as the concrete admixture of the road, but the content of iron mixed in the steel slag is very high, if it is directly used without screening, it will seriously cause a waste of resources; the processing of the steel slag by existing equipment The steel slag is continuously broken, and the small particles with iron are smelted after the small particles are screened. However, due to the large content of the rest of the slag, it is difficult to control the melting temperature during the melting process, resulting in subsequent steel smelting. The quality is difficult to grasp, resulting in material loss, technical problems: provide a magnetic separation equipment for dust absorption type iron powder in steel slag

The invention relates to the field of steel slag, in particular to flying dust adsorption type magnetic separation equipment for iron powder in steel slag. The invention aims to provide the flying dust adsorption type magnetic separation equipment for the iron powder in the steel slag. According to the technical scheme, the flying dust adsorption type magnetic separation equipment for the iron powder in the steel slag comprises a closed cabin, a cabin door and the like; the closed cabin is connected with the cabin door. The steel slag powder is subjected to magnetic separation, a traditional powder adhesion type magnetic separation mode is abandoned, dry powder is subjected to dust raising type magnetic screening in a closed cabin, the collection rate of iron in the powder is increased, and meanwhile iron in the same batch can be completely separated out through magnetic separation; and meanwhile, other powder in the device is uniformly collected to be used as a cement dopant, and the powder running out of gaps in the device is subjected to water immersion type treatment, so that the powder is prevented from flying outside the device.
Description
technical field [0001] The invention relates to the field of steel slag, in particular to a dust-absorbing magnetic separation device for iron powder in steel slag. Background technique [0002] The comprehensive utilization of steel slag as a secondary resource can recover a large amount of metallic iron and other useful elements; in the prior art, steel slag is usually used as a concrete admixture for roads, but the content of iron contained in steel slag is very high, so it can be directly recycled without screening. If it is used, it will seriously waste resources; the treatment of steel slag in existing equipment is to continuously crush the steel slag, and smelt the small particles with iron after the small particles are screened, but due to the large content of the rest of the particles , making it difficult to control the melting temperature during the melting process, making it difficult to grasp the quality of the subsequent melting steel, resulting in material los...
