Description

Technical Field

[0001] The utility model relates to the fields of equipment fixing, transportation packaging, construction site installation and industrial waste treatment, and specifically to a container modular steel tailings treatment equipment for dry-process classification and screening of steel tailings waste generated in the steel smelting process for resource treatment. Background Art

[0002] Steel tailings are byproducts of the steel industry, mainly derived from waste slag in the steelmaking process and residues after steel product processing. They are also slags discharged from the smelting process of converters, electric furnaces, and refining furnaces, which are formed by impurities in metal raw materials, fluxes, and furnace linings, and are mainly composed of silicates, ferrites, and oxides. They mainly include converter slag, electric furnace slag, casting slag, open-hearth slag, etc. The output rate of steel tailings is 12-15% of crude steel production. In recent years, the annual production of steel tailings in my country has basically maintained or exceeded 150 million tons, and the steel tailings produced after crushing and iron selection are also above 130 million tons.

[0003] It is imperative to develop efficient and clean steel tailings waste treatment equipment and processes, realize the resource utilization of steel tailings, and eliminate the environmental pollution caused by steel tailings storage. Good resource utilization of steel tailings can not only produce huge social benefits, but also huge economic benefits, which is of great significance to the healthy development of the steel industry.

[0004] According to the available direction, the main mineral components of steel tailings can be divided into two categories:

[0005] 1) Active minerals similar to Portland cement clinker:

[0006] Calcium silicate, calcium ferrite, calcium aluminoferrite, free calcium oxide, total active mineral content about 55%;

[0007] 2) Iron-rich inert minerals:

[0008] Iron particles Fe, magnetic iron oxide Fe3O4, RO phase MgO, MnO and FeO, among which: iron particles Fe account for about 2-3%, magnetic iron oxide Fe3O4 accounts for about 4.5-7.5%, RO phase accounts for about 35%, and the total iron-rich inert mineral content is about 45%.

[0009] How to dissociate steel tailings waste, sort out different minerals and transform them into high-value products has always been the direction of efforts in this technical field. At present, the steel tailings treatment method adopted by most domestic steel mills is mostly a four-step treatment process, namely "heat-suffocation-crushing-screening-magnetic separation". The equipment and processes are numerous, the slag and iron are not separated thoroughly, the recycled scrap steel has a low grade (TFe content is about 40%), which is not conducive to the use of ironmaking, and the tailings have a high MFe content, resulting in a large waste of resources and poor economic benefits. How to use efficient and simple process equipment to treat steel tailings and produce high-quality scrap steel, iron ore concentrate and easily usable dry tailings is the key to achieving high added value utilization of steel slag.

[0010] At present, the more advanced steel tailings resource processing equipment at home and abroad usually consists of drying unit, grinding unit, classification unit, screening unit, quality separation unit, conveying unit, storage unit, dust collection unit, etc. Among them, the drying unit, grinding unit, and classification unit have been combined and matched. The drying unit uses a hot air furnace to provide hot air, and the hot air is introduced into the mill through the circulating fan to generate negative pressure, so that the temperature in the mill is increased and the material is dried in the mill. The grinding unit uses a roller mill, and the classification unit uses a multi-stage particle sorter connected to the roller mill to receive other light materials selected by the roller mill, and sort other light materials into heavy particles, light particles and steel slag powder according to weight; while the screening unit, quality separation unit, conveying unit, storage unit, dust collection unit, etc. have not yet been integrated. The screening unit includes a vibrating feeder, a vibrating screen, etc.; the quality separation unit includes a magnetic separator; the conveying unit includes a belt conveyor, a quantitative feeder, a screw conveyor, an elevator, etc.; the storage unit uses a storage tank and a steel plate silo; the dust collection unit uses a dust collector. These devices often need to be graded and combined according to the purification requirements of steel tailings, which results in a large number of supporting components and low system integration. There is a long construction period in all aspects of equipment procurement, transportation, installation, and commissioning. In addition, these devices are large in specifications, occupy a large area, and have high requirements on personnel for production operation and maintenance.

[0011] Therefore, how to improve the integration of steel tailings resource processing equipment, make it integrated, modular, and serialized, facilitate rapid on-site assembly and connection, shorten the construction period, facilitate transportation, and enable rapid disassembly, rapid transfer, and reuse are the key issues to be solved next.
