Description

A kind of metallurgical waste slag treatment and recovery equipment

technical field

The invention relates to a metallurgical waste slag treatment system, in particular to a metallurgical waste slag treatment and recovery equipment.

Background technique

Metallurgical waste slag refers to various solid wastes produced in the production process of the metallurgical industry, mainly referring to the blast furnace slag produced in the ironmaking furnace.

The steel slag in the metallurgical waste slag is the solid waste discharged during the steelmaking process, including converter slag, electric furnace slag, etc. The slag removal process in the steelmaking process not only affects the development of steelmaking technology, but is also closely related to the comprehensive utilization of steel slag. At present, the slag discharge treatment process in the steelmaking process can be roughly divided into the following four types: 1. Cold disposal method: the steel slag is poured into the slag tank, and after being slowly cooled, it is directly transported to the slag yard to form a slag mountain. This method was often used in the past; 2. , Hot stone crushing process: use a crane to pour the liquid steel slag in the slag tank onto the slag bed (or in the slag pit) in layers, and spray water at the same time to make it quench and break, and then transport it to the slag yard; 3. Water quenching of the steel slag Process: The discharged high-temperature liquid slag is cut and crushed by the pressure water, and then shrunk and broken when it is quenched by water, and then granulated in the water curtain. The specific methods include the pan-splashing water cooling method, the water flushing method in front of the furnace and the tipping tank-pool method. /t) of 41%, avoiding the problem of slag explosion in contact with water, and improving the operating environment. Steel slag can be air-quenched into hard spheres below 3mm, which can be directly used as fine aggregate for mortar. So far, people have developed a variety of ways of comprehensive utilization of steel slag, mainly including metallurgy, building materials, agricultural utilization, backfilling several fields.

In the prior art, it is often necessary to screen the metallurgical waste slag in the slag field, to screen out the useful steel slag in the metallurgical waste slag, and to separate the steel slag from the slag. The electro-magnetic disk gradually adsorbs the steel slag in the slag field below, and then transfers the adsorbed steel slag to the car. The electromagnetic disk adsorption method of this electromagnetic bridge crane has low work efficiency and can only absorb the steel slag on the surface of the waste slag. The absorbed steel slag in the metallurgical waste slag in the slag field is less than 70%, which greatly reduces the recovery rate of the steel slag. .

When using the metallurgical waste slag treatment and recovery equipment, the waste slag in the slag field is lifted to the top of the waste slag screening mechanism by the waste slag lifting mechanism, and the particularly large solid objects roll down along the inclined vibrating screen 5 to the solid objects. In the collection bucket 58, the remaining waste residue falls onto the conveyor belt 9 through the screen holes on the vibrating screen 5, and the remaining waste residue moves with the conveyor belt 9, and the electro-magnetic disk 34 on the left track 36 on the first adsorption mechanism is continuously rotated. Adsorb the steel slag in the waste slag. The steel slag can turn over by itself due to the inclination when passing through the conveyor belt between the guide wheel III13 and the guide wheel IV14 and between the guide wheel IV14 and the guide wheel V15. Once the steel slag at the bottom of the waste slag enters the upper part during the conveying process, It will be continuously adsorbed by the electro-magnetic disk 34 on the right track 38 on the first adsorption mechanism, and the remaining waste residue falls from the output end of the conveyor belt 9 on the driven wheel 18 to the conveyor belt 9 on the second-stage waste residue conveying mechanism. The conveyor belt 9 on the second-stage waste residue conveying mechanism moves up, and the waste residue on the second-stage waste residue conveying mechanism also flips by itself due to the inclination. Adsorption, the recovery speed of steel slag is not only faster, but also greatly improves the recovery rate of steel slag, and the recovery rate of steel slag can reach more than 90%.
