Description

Automatic environmental protection of bold slag breaking device that drops into a hammer

Technical Field

The utility model relates to a slag processing technology field, in particular to an automatic environment-friendly drop hammer crushing device for large steel slag.

Background

In recent years, the annual steel yield of China exceeds 8 hundred million tons, which accounts for about 120-140 kg of steel slag generated by producing one ton of steel, and the annual steel slag generation amount of China exceeds 1 million tons. The large steel slag is an important component of steel slag, the yield of the large steel slag is about 7% -10% of that of common steel slag, and for a large-scale steel enterprise, the annual yield of the large steel slag is usually more than 5 ten thousand tons. Because the bulk steel slag contains higher iron content, the metal iron content of the bulk steel slag is usually over 50 percent, and the bulk steel slag has important iron resource recycling value.

In the production process of iron making and steel making, slag lumps (slag irons) are inevitably generated at the positions of a pig casting machine, a converter mouth, molten iron slag removal, a ladle trolley, continuous casting residual slag and the like or in the production process, and the slag lumps cannot be processed by cutting due to high slag content, high iron content and the like, but the slag cannot be directly returned to the steel making production due to overlarge volume. Therefore, the massive steel slag is a difficult problem in steel slag treatment, and a reasonable crushing process is urgently needed. At present, the conventional crushing and screening magnetic separation line aims at steel slag with granularity smaller than 300mm, and large-volume steel slag is crushed by special equipment such as a drop hammer, a crusher and the like. A large number of practices show that the large-volume steel slag can be effectively crushed by crushing the large steel slag in a drop hammer mode, and the slag and iron can be efficiently separated. After the large steel slag is subjected to drop hammer treatment, the steel slag is separated out by an electromagnetic chuck and is recycled.

The traditional hammer dropping process is often quite lagged behind, the outdoor hammer dropping process is generally adopted for treatment, the environment of the treatment process is poor, the adverse phenomena of steel slag splashing, dust overflowing, noise like thunder and the like exist, the ecological environment of an enterprise is seriously influenced, and the potential safety hazard of manual operation danger exists. Therefore, the problem in the process of crushing the massive steel slag needs to be solved by adopting a high-automation, safe and environment-friendly drop hammer crushing process in a closed space in a factory building.

The novel hammer-dropping process and equipment are developed aiming at the problems that the existing hammer-dropping process is poor in environmental tightness, high in danger of manual operation caused by steel slag splashing, poor in smoke and dust unorganized emission environment, large in noise caused by hammer-dropping crushing and the like. Therefore, the novel automatic environment-friendly drop hammer crushing method and device for the large steel slag have the advantages of high equipment automation level, high production efficiency, organized environmental emission, low production noise and the like. The technology realizes the environment-friendly treatment of the large steel slag drop hammer crushing, obviously improves the crushing efficiency of the large steel slag, and is the leap-type upgrade of the existing steel slag drop hammer process technology equipment.
