Comprehensive utilization and treatment device and method for solid waste of steel plant

Abstract

The invention discloses a comprehensive utilization and treatment device and method for solid waste of a steel plant, and relates to the technical field of waste treatment. The comprehensive utilization and treatment device comprises a cleaning outer box, a cleaning inner box, a lifting turnover mechanism, a drying mechanism, a crushing box, a metal adsorption box and ball milling equipment, wherein the cleaning inner box is arranged in the cleaning outer box, the cleaning inner box is fixed on the lifting turnover mechanism, the drying mechanism is arranged behind the lifting turnover mechanism, the crushing box is arranged below the right end of the drying mechanism, and the metal adsorption box is arranged below the crushing box. According to the comprehensive utilization and treatment device and method, the cleaning function is achieved for the solid waste of the steel plant, after the waste is subjected to secondary crushing, all components can be adsorbed more tightly, the brick making quality is greatly improved, automatic material transferring is adopted in the whole process, the treatment efficiency of the whole device is improved, and the problems that the quality of bricks prepared by an existing treatment device and method is common, the brick making operation efficiency is low, and large-scale popularization and use are difficult to achieve in practice are solved.

Description

technical field [0001] The invention belongs to the technical field of waste treatment, and in particular relates to a comprehensive utilization treatment device and method for solid waste in a steelmaking plant. Background technique [0002] Solid waste refers to the solid and semi-solid waste materials generated by human beings in production, consumption, life and other activities. In layman's terms, it is "garbage". Three categories of waste and domestic waste, industrial waste, including mining waste rock, smelting waste residue, various coal gangue, slag and metal cutting fragments, building bricks, tiles, stones, etc.; agricultural waste, including crops Straw, livestock manure, etc.; domestic waste, that is, domestic garbage, and industrial solid waste are mainly various waste residues, sludge, and dust discharged into the environment during industrial production and processing, among which waste residues are the main ones. It has the characteristics of large size, m...

AI Technical Summary

Problems solved by technology

[0006] 1. The quality of the bricks produced by the treatment device and method is average, it is difficult to completely mix the materials only by the mechanical stirring device, the physical and chemical properties of the bricks are not ideal, and the strength of the bricks is poor;

[0007] 2. The brick-making operation efficiency of this treatment device and method is low, and it is actually difficult to popularize and use it on a large scale

[0008] Therefore, the existing processing devices and methods cannot meet the needs in actual use, so an improved technology is urgently needed on the market to solve the above problems
