Description

Metallurgical waste residue screening machine

Technical Field

The invention relates to a metallurgical waste residue treatment system, in particular to a metallurgical waste residue screening machine.

Background

The metallurgical waste slag refers to various solid wastes generated in the production process of metallurgical industry, and mainly refers to blast furnace slag generated in an iron-making furnace.

The steel slag in the metallurgical waste slag is solid waste discharged in the steel-making process, and comprises converter slag, electric furnace slag and the like. The slag discharge process in the steelmaking process not only influences the development of the steelmaking technology, but also is closely related to the comprehensive utilization of the steel slag. At present, the slag discharge treatment process in the steel making process can be roughly divided into four types: 1. a cold discard method: pouring the steel slag into a slag pot, and directly transporting the steel slag to a slag yard to be stacked into a slag mountain after the steel slag is slowly cooled; 2. a hot splashing stone breaking process: pouring liquid steel slag in the slag tank on a slag bed (or in a slag pit) layer by using a crane, spraying water to quench and crack the liquid steel slag, and then conveying the liquid steel slag to a slag yard; 3. the steel slag water quenching process comprises the following steps: the discharged high-temperature liquid slag is cut and crushed by pressurized water, and is rapidly quenched and shrunk when meeting water to be broken and granulated in a water curtain. The concrete method also comprises a plurality of methods such as a water cooling method by disc splashing, a water flushing method in front of a furnace, a tilting tank-water tank method and the like; 4. a wind quenching method: the method has the main advantages that 41 percent of heat (about 2100-2200 MJ/t) contained in the high-temperature slag can be recovered, the problem of slag explosion when meeting water is avoided, and the operating environment is improved. The steel slag can be air-quenched into hard spheres with the diameter of less than 3mm, and can be directly used as fine aggregate of mortar. Until now, various approaches related to the comprehensive utilization of steel slag have been developed, mainly including several fields of metallurgy, building materials, agricultural utilization and backfilling.

In the prior art, metallurgical slag in a slag field is often screened, useful steel slag in the metallurgical slag is screened out, the steel slag and slag soil are separated, an electromagnetic disc is adopted to adsorb the steel slag, an electromagnetic disc is driven by an electromagnetic bridge crane to gradually adsorb the steel slag in the lower slag field, and then the adsorbed steel slag is transferred to a vehicle. The electromagnetic disk adsorption mode of the electromagnetic bridge crane has low working efficiency, and can only adsorb steel slag on the surface of the slag, and the adsorbed steel slag in metallurgical slag in a slag field is not more than 70 percent, thereby greatly reducing the recovery rate of the steel slag.
