Description

Technical Field

[0001] The utility model relates to the technical field of dust suppression equipment, in particular to a dust suppression device for mining. Background Art

[0002] During mining operations, semi-sealed mines will generate a large amount of dust, which poses a great threat to the health of workers. Dust suppression equipment is needed. Spray dust suppression is one of the commonly used dust suppression methods. Its principle is to use the particles generated by the spray. Because of their extremely small size and basically zero surface tension, they can quickly absorb various dust particles of different sizes in the air when sprayed into the air, thus forming effective dust control.

[0003] The water mist nozzles of current spray equipment mostly point in a single direction, and the sprayed water mist mostly covers a fan-shaped area. Although the spray angle of some equipment can be adjusted, the adjusted spray pattern remains unchanged, making it difficult to achieve large-scale coverage. Utility Model Content
