Steel smelting furnace slag multistage recovery device

Abstract

The invention discloses a steel smelting furnace slag multistage recovery device. The steel smelting furnace slag multistage recovery device comprises a first machine body, a material storage cavity is formed in the first machine body, the material storage cavity is internally provided with a material storage mechanism for storing steel smelting furnace slag for unified treatment, the bottom wall of the material storage cavity is provided with a milling cavity, a milling mechanism for milling the steel smelting furnace slag is arranged in the milling cavity, wherein the milling mechanism comprises a main milling wheel and an auxiliary milling wheel. According to the steel smelting furnace slag multistage recovery device, iron-containing particles are screened out of steel smelting furnace slag powder formed after milling and grinding by utilizing magnetic force, iron in the steel smelting furnace slag is recycled through the steel smelting furnace slag multistage recovery device, so that the effects of being green and environment-friendly are achieved, in addition, before milling and grinding are performed, the device stores the steel smelting furnace slag and then performs milling and grinding in a unified mode, so that a motor does not need to be started for a long time for milling and grinding, so that the energy is saved, the environment is protected, the service life is long, during grinding, the ground powder is high in fineness, the subsequent magnetic screening accuracy is high, during magnetic screening, material falling of the device is accurate and errorless, the iron particle recovery rate is high, the automation degree of the whole recycling process is high, and the reaction is sensitive.

Description

technical field [0001] The invention relates to the field of industrial waste recycling, in particular to a multi-stage recycling device for steelmaking slag. Background technique [0002] As we all know, in order to remove harmful impurity elements and non-metallic inclusions from the refined steel, it is often necessary to add a slagging agent during steelmaking. The slagging agent will produce steelmaking slag during the steelmaking process. There are some steel scraps and small steel balls mixed in. If these scraps are not screened, they will be discarded together with the steelmaking slag, which is a waste of steel resources. Therefore, it is necessary to recycle the steel in the steelmaking slag; the traditional steelmaking slag recovery device The degree of automation is low, and workers need to stare at the device to control the recycling process step by step during recycling; in addition, the traditional steelmaking slag has a single function, requiring additional c...

[0002] As we all know, in order to remove harmful impurity elements and non-metallic inclusions from the refined steel, it is often necessary to add a slagging agent during steelmaking. The slagging agent will produce steelmaking slag during the steelmaking process. There are some steel scraps and small steel balls mixed in. If these scraps are not screened, they will be discarded together with the steelmaking slag, which is a waste of steel resources. Therefore, it is necessary to recycle the steel in the steelmaking slag; the traditional steelmaking slag recovery device The degree of automation is low, and workers need to stare at the device to control the recycling process step by step during recycling; in addition, the traditional steelmaking slag has a single function, requiring additional crushing and crushing equipment for simultaneous production, and the economic benefit is low; during production, the equipment needs to be turned on for a long time Continuous crushing and crushing, or manual collection of steelmaking slag and then manually adding it to the crushing and crushing equipment, the operation is complicated and cumbersome, and the production cycle is long; therefore, it is necessary to design a multi-stage recovery device for steelmaking slag to solve the above problems question
