Description

Technical Field

[0001] This utility model relates to the field of slag powder technology, specifically to a screening device for slag powder processing. Background Technology

[0002] Slag powder, also known as granulated blast furnace slag powder, is a high-quality concrete admixture. It is obtained from granulated blast furnace slag conforming to GB / T203 standards through drying, grinding, and other processes, resulting in a powder with considerable fineness and activity index. Granulated blast furnace slag is an industrial solid waste residue obtained from the molten material, primarily composed of calcium aluminosilicate, during pig iron smelting in blast furnaces. This residue is granulated after water quenching and is mostly glassy, ​​possessing potential hydraulic cementitious properties. Slag powder has wide applications in various fields. In the construction industry, it can be used as a concrete admixture to improve the durability, impermeability, and corrosion resistance of concrete. It can also be used as a raw material for fireproofing materials and building components such as thermally broken aluminum windows and doors. In the road and bridge industry, slag powder can be used for foundation or pavement improvement and reinforcement, enhancing load-bearing capacity and stability. Furthermore, slag powder plays an important role in environmental protection, being used for urban environmental remediation and ecological greening, such as remediating contaminated soil and constructing landfills. The manufacturing process of slag powder mainly includes crushing, grinding, classification, drying, and packaging. Common crushing equipment includes jaw crushers, cone crushers, and double roll crushers. Grinding is usually carried out using a mineral mill to improve the fineness and activity of the slag. The classification step is to remove excessively coarse or fine particles to obtain a product that meets the requirements.

[0003] According to patent number CN215430231U published on the China Patent Network, this utility model discloses a multi-stage screening device for slag powder processing. Rollers distributed in a ring are uniformly fixed to the lower side of the outer circumference of the inner cylinder. The inner wall of the screening box has annular grooves corresponding to the positions of the rollers. The rollers and annular grooves are in rolling cooperation. The inner cylinder is mounted on a fixed ring. A short shaft is fixed to the lower end of the central block. A bevel gear is fixed to the lower end of the short shaft. A horizontal shaft is fixed to the end of the output shaft of motor one. A bevel gear two that meshes with bevel gear one is fixed to the right end of the horizontal shaft. A filter screen one is fixed to one side of the lower opening of the screening cylinder. The vertical section of the lower side of the feed pipe extends into the fixed box. A filter screen two is fixed to one side of the lower opening of the rectangular frame. The fixed block slides with the guide rod on the corresponding side through the through hole. A spring is fitted on the guide rod placed between the left side wall of the fixed box and the left end face of the rectangular frame.
