This utility model relates to the field of mining blasting technology and provides a dust suppression device after open-pit mine blasting. The device includes a main body with a water tank fixedly installed inside. A water injection
pipe is fixedly embedded in the right side of the water tank, and the outer surface of the water injection
pipe is fixedly embedded in the rear side of the main body. It also includes a feeding component fixedly embedded inside the main body. In use, the design of the feeding tray and stirring blade structure allows for precise control of the dust suppressant dosage each time, while effectively mixing the dust suppressant and water to ensure a fully uniform distribution. This enhances the adhesion of the sprayed water mist particles, enabling them to adhere more effectively to the surface of fine
dust particles, increasing the
settling velocity of the
dust particles. This improves the
settling velocity of fine particles and reduces the likelihood of them being blown away by the wind.
