Description

Technical Field

[0001] The utility model relates to the technical field of red mud utilization, in particular to a red mud slurry dilution device. Background Art

[0002] Red mud is an industrial solid waste discharged when the aluminum industry extracts alumina. It is called red mud because it contains a large amount of iron oxide and looks similar to red soil. Due to the difference in ore grade, production method and technical level, about 1.0 to 1.8 tons of red mud are discharged for every ton of alumina produced. As the stockpile of red mud increases and the pollution to the environment becomes more and more serious, it is urgent to maximize the resource utilization of red mud.

[0003] At present, the main process of extracting iron powder from alumina red mud is: after the red mud material is subjected to cyclone classification, the bottom flow is screened by magnetic separation, and then dehydrated by a filter to finally produce iron powder. However, due to the fine particle size of the red mud, most of the ultrafine iron powder is taken away with the slurry during the cyclone classification and magnetic separation process, resulting in a decrease in the iron powder output of the process and affecting the red mud reduction rate. Therefore, it is necessary to separate this part of fine iron powder from the mud through a stronger centrifugal separation effect to improve the iron powder output and quality. Prior to this, the red mud slurry needs to be diluted to a greater extent to reduce the viscosity of the slurry to facilitate subsequent separation. In the prior art, the red mud slurry is generally poured into a trough, a diluent is added, and then diluted and mixed by a stirring device. After completion, the red mud slurry needs to be unloaded and the diluted slurry is input into a centrifugal separation device through a conveying device. The entire dilution process requires the cooperation of multiple equipment, supplemented by manual operation and transportation, which affects the processing efficiency. Therefore, the utility model proposes a red mud slurry dilution device to solve the problems existing in the prior art. Utility Model Content
