Slag water separation apparatus

Abstract

The invention belongs to the technical field of steel metallurgy, and concretely relates to a slag water separation apparatus. The apparatus comprises a slag tank, a centrifuging disc is arranged at the center of the slag tank, the centrifuging disc can rotate along the self axis, a first driving motor for driving the centrifuging disc to rotate is arranged in the slag tank, the inner wall of theslag tank is provided with a cooling water jacket, a spraying device is arranged at the top of the slag tank, the centrifuging disc is assembled to be able to perform conical pendulum movement along avertical axis, and a driving mechanism for driving the centrifuging disc to perform conical pendulum movement is arranged in the slag tank; and a slag water collecting pool is arranged at the bottomof the slag tank, an overflow member is arranged at the upper end of the slag water collecting pool, a sediment tank is arranged at the lower end of the slag water collecting pool, a slag dredging mechanism is arranged in the sediment tank, and an aeration tube is arranged at the bottom of the slag water collecting pool. The slag water separation apparatus has the advantages of directness in collection of steel slag and wastewater generated in the slag granulation process, implementation of cleaning and separating works in the first time, improvement of the recycling efficiency of the steel slag, compact structure and small occupied space.

Description

technical field [0001] The invention belongs to the technical field of iron and steel metallurgy, and in particular relates to a slag-water separation device. Background technique [0002] Steel slag is a by-product of the steelmaking process, which is formed by the oxidation of silicon, manganese, phosphorus, sulfur and other impurities in pig iron during the smelting process and the salts formed by the reaction of these oxides with solvents. composition. There are two main ways to comprehensively utilize steel slag as a secondary resource. One is to recycle steel slag in our factory as a smelting solvent, which can not only replace limestone, but also recover a large amount of metallic iron and other useful elements from it; , construction materials or raw materials for agricultural fertilizers. The treatment of steel slag mainly includes processes such as water quenching, granulation, cooling, cleaning, and powder grinding. However, the process of steel slag treatment i...

AI Technical Summary

Problems solved by technology

The treatment of steel slag mainly includes processes such as water quenching, granulation, cooling, cleaning, and powder grinding. However, the process of steel slag treatment in the prior art is relatively scattered, the equipment occupies a large space, and the production efficiency is low. It is difficult to adapt to the fast-paced metallurgical industry. production demand
