Centrifugal counter-impact efficient atomization mining dust fall spraying nozzle

The invention discloses a centrifugal counter-impact efficient atomization mining dust fall spraying nozzle suitable for atomization of water and other liquid media. The centrifugal counter-impact efficient atomization mining dust fall spraying nozzle comprises a connector separation chamber, a spiral rod and a spraying head, wherein the connector separation chamber is divided into an inlet connector and an outlet separation chamber which are communicated through two hole passages; the spiral rod is arranged in the separation chamber and positioned through a positioning pin; two spiral grooves in the same spiral direction are formed in the spiral rod and spaced by 200 degrees on the rod; two section-variable bending holes are symmetrically distributed in two sides of a central hole of the spraying head; the inlet connector divides liquid into two flows, the liquid is subjected to centrifugal acceleration through the spiral rod, and finally the two flows of liquid impact each other through the bending hole passages, so that atomization of the liquid is improved. The atomization effect of the spraying nozzle is better than that of a common spraying nozzle, the atomization effect which is achieved by the common spraying nozzle at the water pressure of 4 MPa can be achieved by the centrifugal counter-impact efficient atomization mining dust fall spraying nozzle at the inlet water pressure of 1 MPa, and the centrifugal counter-impact efficient atomization mining dust fall spraying nozzle is good in atomization effect, convenient to dismount and mount, and not prone to blockage.
