Description

Technical Field

[0001] The invention relates to the technical field of brick making, and in particular to a device for making bricks by sintering tailing mud and doping it with sewage sludge. Background Art

[0002] The physical characteristics of iron tailings are characterized by fine particle size, mostly ranging from a few microns to several hundred microns, with varying densities. Freshly discharged tailings have a high moisture content and are in a slurry state. Chemically, iron tailings are generally of low grade and may contain other valuable metal elements (such as copper) and non-metallic elements (such as phosphorus), which offer the potential for comprehensive utilization of solid waste. However, iron tailings may also have a certain impact on the environment. For example, acidic wastewater produced by oxidation may pollute surrounding water bodies and soil, and heavy metal elements leaked from stacking may also harm the ecological environment.

[0003] In recent years, the use of solid waste in the preparation of building materials has become a major research direction in the recycling of iron ore tailings. Preliminary XRF testing revealed that iron ore tailings are rich in Fe2O3 and SiO2, meeting the requirements of the building materials industry as an ingredient in silicate cement admixtures and can replace volcanic ash admixtures after sintering. Furthermore, because the iron content of tailings far exceeds 5%, meeting the standards for sintered brick production, preliminary studies have found that calcining tailings mixed with coal powder to make bricks has achieved good results. Furthermore, by blending tailings and sewage sludge, pollution and carbon emissions can be effectively reduced, enabling the transformation and upgrading of the traditional building materials industry to a production model of efficient resource recycling and green manufacturing. This effectively digests existing iron ore tailings and municipal sewage sludge, synergistically promoting carbon reduction, pollution reduction, green expansion, and growth, and driving continuous progress in green and low-carbon development.

[0004] The process of making bricks from tailings and sludge mainly includes drying, crushing, mixing, pressing, sintering and other processes. Among them, the mixed mixture is placed in a mold box for pressing. The mixture needs to be shaken and arranged in each brick cavity of the mold box for pressing and molding. The current brick-making equipment uses one-way feeding, so that each process must wait until the previous process is completed before it can be carried out, resulting in low brick-making efficiency. Summary of the Invention
