AI Technical Summary
Existing dust suppression equipment for coal conveyor belts is ineffective at handling coal dust accumulated at the bottom of the belt, resulting in a large amount of dust generated at the bottom of the coal during transportation and insignificant dust suppression effect.
A dust-suppressing belt conveyor device was designed, which uses vertical and oblique nozzles combined with a spiral blade turning mechanism. The vertical and oblique nozzles spray clean water from different angles, and the dustproof net blocks the spread of dust. At the same time, the spiral blade turns the coal to improve the spraying effect, and the inner nozzle further suppresses dust inside the coal.
It achieves uniform dust suppression of coal above and below the conveyor belt, reduces dust diffusion, and improves the dust suppression effect during coal transportation.
