Description

Technical Field

[0001] The present invention relates to the technical field of tape washing and dust removal in transfer machine rooms, and particularly relates to a tape washing and dust removal device for a bauxite transfer machine room. Background Art

[0002] Bauxite refers to the general term for ores that can be utilized industrially and mainly composed of gibbsite and boehmite. Bauxite is the best raw material for producing metallic aluminum and also the most important application field, with its consumption accounting for more than 90% of the total global bauxite output.

[0003] During the transfer process of bauxite in the transfer machine room, a large amount of dust is easily generated, and some bauxite adheres to the belt conveyor. During the dust removal and cleaning processes, a large amount of water is required. When the amount of water is small, the functions of dust removal and cleaning cannot be achieved; when the amount of water is large, the diluted bauxite adheres to equipment such as the belt conveyor, chute, and feed chute. There is a need for a tape washing and dust removal device that can recycle water sources and timely clean and recover slag. Summary of the Invention
