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 tailings and doping them with sewage sludge. Background Art

[0002] The physical characteristics of iron tailings are fine particle size, mostly ranging from a few microns to hundreds of microns, with different densities, and freshly discharged tailings with high moisture content and slurry-like appearance. In terms of chemical characteristics, iron tailings are usually of low grade and may contain other valuable metal elements (such as copper) and non-metallic elements (such as phosphorus), which provide possibilities for the comprehensive utilization of solid waste. However, iron tailings may also have certain impacts 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 cause harm to the ecological environment.

[0003] In recent years, the use of solid waste in the preparation of building materials has become the main research direction for the recycling of iron ore tailings. Preliminary XRF testing found that iron ore tailings are rich in Fe2O3 and SiO2, which meets the needs of the building materials industry as a silicate cement admixture ingredient, and can replace volcanic ash admixtures after sintering. In addition, since the iron content of tailings far exceeds 5%, it meets the standard for sintered brick production. Preliminary studies have found that the calcination of tailings mixed with coal powder to make bricks has achieved good results. In addition, by mixing tailings and sludge, pollution and carbon can be effectively reduced, and the traditional building materials industry can be transformed and upgraded to a production model of efficient recycling of resources and green manufacturing. The existing iron ore tailings and urban sludge can be effectively digested, and carbon reduction, pollution reduction, green expansion, and growth can be promoted in a coordinated manner, and new progress can be made in promoting 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.
