A dust suppression device after blasting in an open-pit mine

By using a discharge pan and agitator blade structure to mix dust suppressant and water after blasting in an open-pit mine, the adhesion of water mist particles is enhanced, solving the problem of slow settling speed of fine particles by water mist in existing technologies, and achieving a more effective dust suppression effect.

AI Technical Summary

Technical Problem

Existing dust suppression devices in open-pit mines use mist cannons to spray water mist to suppress dust, but this method has the problem of slow settling speed for finer particles and easy for them to be blown away by the wind.

Method used

The material is fed into a feeding tray and a stirring blade structure to precisely control the dust suppressant dosage. After being mixed with water, it is sprayed through a mist cannon to enhance the adhesion of the water mist particles and ensure the settling speed of fine dust particles.

Benefits of technology

It increases the settling speed of fine dust particles, reduces the possibility of them being blown away by the wind, and achieves a more effective dust suppression effect.

Abstract

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.
