Specific embodiment
Below in conjunction with the attached drawing in the present invention, technical solution in the embodiment of the present invention is clearly and completely retouched
It states, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.
Referring to Fig.1 ~ Fig. 3, a kind of New Mine non-circulating drilling aperture device for reducing dust, including dust extractor 1, dust suppressant addition pump
5, air hose 7, water pipe 6, Venturi tube 8, electromagnetic valve 4, scum pipe 11, threaded nozzle 3, atomization spray orifice 10.Dust extractor 1 is whole embedding
Enter at coal bed drilling aperture, dust extractor 1 divides for two parts: upper inner wall is equipped with threaded nozzle 3, arranges along inner wall direction, screw thread
Nozzle 3 is fixed on inner wall by screw thread 15, is water cavity 2, the outer connection solenoid valve door 4 of water cavity 2, water cavity 2 and venturi above nozzle
Pipe 8 is connected by electromagnetic valve 4, and 8 import of Venturi tube connects air hose 7, and upper end connects water pipe 6 and dust suppressant addition pump 5, catches dirt
