Description

Technical Field

[0001] The utility model belongs to the technical field of red mud environmental protection treatment, in particular to a mixing device between conveyor belts. Background Art

[0002] Red mud is an industrial solid waste produced when alumina is extracted in the aluminum industry. Its main components include iron oxide, silicate, etc. Due to its strong alkalinity and fine powdery structure, it will occupy a large amount of land and pollute the soil and groundwater when stored. At the same time, it will cause dust hazards when encountering strong winds.

[0003] Currently, red mud is generally treated by chemical reduction reaction. The mixed material is roasted to extract high-grade metals, and the remaining tailings are used for construction.

[0004] Before mixing the red mud, it needs to be dried, crushed, and then mixed with the material. During the mixing stage, the material is conveyed into a mixing device through a conveyor belt and mixed by stirring.

[0005] In actual use, due to the limitation of the construction area of ​​the factory and for cost considerations, it is impossible to install two or more conveyor belts end to end. Therefore, there is a certain angle between the two conveyor belts. Therefore, when the material body is sent out again, a chute is often needed to guide the material body, and the material body is mixed into a stirring device through the chute. This restricts the equipment during maintenance and movement, and it is not very convenient to use. In addition, the existing stirring device generally adopts a paddle stirring mechanism when mixing. When the paddle stirring mechanism encounters a large mass of red mud mixture, the resistance encountered becomes greater, which limits the quality of stirring and mixing. Now the mixing mechanism is improved to enhance the mixing efficiency. Utility Model Content
