Steel plant solid waste comprehensive utilization and treatment method

Abstract

The invention relates to a steel plant solid waste comprehensive utilization and treatment method. The method mainly comprises the following steps of raw material classification, mineral powder preparation, screening and stirring, brick making operation and other various procedures. Steel slag screening and stirring equipment used in the method comprises a bottom plate, an adjusting device, a screening device and a stirring device. The method can solve the following problems existing during existing steel slag screening and stirring that a, during traditional steel slag screening, steel slag is usually screened manually through a screen, the labor intensity of manual screening is large, the screening efficiency is low, and the brick making efficiency is reduced; and b, when existing steelslag screening equipment is used for screening the steel slag, screening operation is usually conducted through a vibration screen, the gap of the screen cannot be adjusted, only fixed steel slag blocks can be screened, the screened steel slag cannot be stirred, and the steel slag screening efficiency is reduced.

Description

technical field [0001] The invention relates to the technical field of solid waste treatment, in particular to a method for comprehensive utilization and treatment of solid waste in steelworks. Background technique [0002] There is a large amount of steel slag in the solid waste of the steelmaking plant. The steel slag is the solid waste produced by the steelmaking plant. It contains 20%-30% iron, especially a large amount of Fe3O4, so it is gray and black, which creates a great opportunity for the preparation of antique bricks. Very good conditions, not only have excellent chromaticity conditions, but also have the coarse aggregate and fine aggregate required for brick preparation, which greatly reduces the production cost of bricks, and steel slag needs to be screened before use . [0003] However, the following problems exist in the existing steel slag screening and mixing, a, the traditional steel slag screening is usually carried out manually through the screen mesh t...

AI Technical Summary

Problems solved by technology

[0003] However, the following problems exist in the existing steel slag screening and mixing, a, the traditional steel slag screening is usually carried out manually through the screen mesh to screen the steel slag, the labor intensity of manual screening is high, and the screening efficiency is low, which reduces the The production efficiency of bricks; b When the existing steel slag screening equipment screens steel slag, it usually screens through vibrating screens, and the gap between the screens cannot be adjusted, and only fixed steel slag blocks can be screened, and It is impossible to mix the screened steel slag, which reduces the efficiency of steel slag screening
