A red mud permeable brick sintering equipment

Abstract

The invention discloses red mud breathable brick sintering equipment. By virtue of the red mud breathable brick sintering equipment, automatic feeding and sintering of porous bricks can be realized; in addition, the sintering time can be controlled based on the rotating speed of sintering ceramic discs, so that the sintering control precision and the sintering quality are greatly improved; and sintering is carried out by adopting a ceramic disc mode, so that the uniformity and stability of sintering are ensured, green brick feeding and discharging can be performed automatically, manual operation is not needed, the sintering safety and the automation degree are greatly improved, the sintering time and the sintering temperature are controlled accurately, and high-efficiency sintering is guaranteed.

Description

technical field [0001] The invention relates to a red mud permeable brick sintering equipment, which belongs to the technical field of red mud permeable brick preparation equipment. Background technique [0002] Red mud is the polluting waste slag discharged when the aluminum industry extracts alumina. Generally, for every ton of alumina produced, 1.0 to 2.0 tons of red mud are incidentally produced. As the fourth largest producer of alumina in the world, my country discharges millions of tons of red mud every year. At present, a large amount of red mud cannot be fully and effectively utilized, and can only be stacked in large-scale storage yards, which occupies a large amount of land and causes serious pollution to the environment. The red mud produced in the world is about 70 million tons every year, and the red mud produced in my country is more than 30 million tons every year. [0003] Therefore, the reuse of red mud plays an extremely important role in alleviating env...

Problems solved by technology

[0003] Therefore, the reuse of red mud plays an extremely important role in alleviating environmental pollution. Among them, one of the important functions of red mud is to prepare red mud into breathable bricks, and the steps of preparing red mud breathable bricks include mixing materials, making Blank, sintering and cooling. The current sintering equipment is generally realized by sintering furnace or sintering kiln. This kind of equipment not only requires a large labor force during sintering, but also takes a long time for loading and unloading, resulting in the sintering of the bricks that were charged in the morning. The sintering time is long, while the sintering time of the adobe of the evening material is short, and the sintering time is uneven, resulting in unstable sintering quality
