Description

Technical Field

[0001] The utility model relates to the technical field of blasting, in particular to a dust removal device for open-air blasting. Background Art

[0002] Blasting is a project that uses the huge pressure generated by the explosion of explosives in soil, rock or objects to break the soil, rock or objects. In order to achieve a good blasting effect, the mass of explosives required in the blasting process is usually calculated based on the soil quality and blasting area. Then, based on the calculated amount of explosives, several blast holes for placing explosives are opened on the ground and explosives are installed in the blast holes.

[0003] Blasting operations will generate dust with high dust concentration, fine dust particles and extremely slow natural settling speed, which is not conducive to shortening the operation cycle time. Traditional dust removal uses water spraying to sink the dust, but its coverage area is small and the dust removal effect is not ideal in actual application. Based on this, the utility model proposes a dust removal device for open-air blasting that can solve the above problems. Utility Model Content

[0029] The water pump can pump the water in the water tank 22 and transport it to the atomizing nozzle 24 through the water pipe 23, and then the water is sprayed out through the atomizing nozzle 24 to remove dust.

[0030] The driving assembly 40 is used to drive the first lining rod 21 to move upward to raise the atomizing nozzle 24. That is, when performing open-air blasting, the driving assembly 40 drives the first lining rod 21 to move upward to raise the height of the water mist sprayed by the atomizing nozzle 24, thereby effectively increasing the coverage range and achieving a good dust removal effect.
