The outlet of the dust suppressant regulating valve 22 is connected to the second inlet of the mixing chamber 24. During the process of water entering the mixing chamber 24 through the water flow regulating valve 21, a negative pressure is generated at the second inlet of the mixing chamber 24, drawing the dust suppressant into the mixing chamber 24. Water and dust suppressant mix in the mixing chamber 24, forming... The mixture is formed into a liquid, and the mixing ratio of water and dust suppressant is adjusted by water flow regulating valve 21 and dust suppressant regulating valve 22.
