AI Technical Summary
Existing dust suppression technologies in mines are insufficient in terms of synergistic improvement of dust interception and dust suppression efficiency, resulting in the inability to effectively prevent dust diffusion, limited dust suppression effect, and failure to meet the actual needs of dust control in mines.
The design incorporates interception and dustproof components. The interception component consists of a pleated curtain and a T-shaped pull plate, forming a horizontal interception barrier. The dustproof component uses a spring and sealing plate structure to prevent dust from entering the nozzle. Combined with the reciprocating oscillating spray of the nozzle, it increases the probability and time of contact between dust and water.
It effectively prevents dust from spreading, improves dust suppression efficiency, prevents nozzle clogging, extends the residence time of dust in the spray area, and enhances the dust suppression effect in the mine tunnel.
