The present invention is that technical solution problem adopts following technical scheme:
The design feature of mine wet-type air-actuated dust-cleaning equipment of the present invention is: the front end at mixing wastewater with air cylinder is equipped with wind gathering cover; Be arranged on one end that air motor in mixing wastewater with air cylinder is in wind gathering cover place, described air motor is coaxial both-end output motor, the front end impeller being arranged on the front end output shaft of air motor is to be in wind gathering cover place one side, and the rear end impeller being arranged on the rear end output of air motor is the front end that is in mixing wastewater with air cylinder; On described mixing wastewater with air cylinder, position between described front end impeller and rear end impeller is provided with front end atomization mechanism, the middle part that is positioned at described mixing wastewater with air cylinder is provided with rear end atomization mechanism, is in the mixing wastewater with air cylinder at rear portion of described rear end impeller and is provided with water conservancy diversion deduster; Described water conservancy diversion deduster comprises the spiral stream guidance ring on the inside wall that is horizontally disposed each metafiltration core and is positioned at mixing wastewater with air cylinder, and described spiral stream guidance ring is the periphery that is in described each metafiltration core.
The design feature of mine wet-type air-actuated dust-cleaning equipment of the present invention is also:
Described filter core is arranged with multiple tracks in parallel.
On the afterbody base plate of described mixing wastewater with air cylinder, be provided with sewage draining exit.
Compared with the prior art, beneficial effect of the present invention is embodied in:
1, the present invention adopts bilobed wheel structure, and ventilation can reach 180m
3/ min, has significantly improved the ability of processing dust.
2, reasonable Arrangement atomization mechanism of the present invention, is included between front end impeller and rear end impeller front end atomization mechanism is set, and has effectively improved dust removing effects;
3, in the present invention, be arranged so that water smoke and the dust on mixing wastewater with air cylinder inside wall of water conservancy diversion deduster can condense by reduction of speed, is more conducive to buck and mixes, and can improve equally dust removing effects;
4, the present invention's filter core is set to multiple tracks, can effectively improve the chance of dust and water collision, further improves dust removing effects.
5, explosion-proof, the antistatic of the present invention, safe and reliable, water-saving efficient.
