Description
Technical field
The present invention relates to a kind of ventilation terminal, particularly a kind of driving face ventilation terminal.
Background technology
Coal mine down-hole tunnel is in tunneling process, it will produce a large amount of coal dusts, due to " stifled for one in front of the tunnel in driving
Head ", therefore, mutually this is bigger in other positions for coal dust amount, and substantial amounts of coal dust not only serious infringement workman's is healthy, simultaneously
Also seriously threaten the production safety of mine.Therefore, typically in tunneling process, especially using the pick of comprehensive mechanization equipment
During entering, can arrange that synchronous blower fan is aerated dedusting in driving face.
Driving face typically presses the short dust removal by ventilation mode taken out using long, distinguished and admirable is delivered to fresh with forced blower fan
Then dirty wind carried out purifying by exhaust fan and extract out by work surface, but using the long headwork pressing short odd test blower fan
Face, forced air duct be vertically give driving face air feed, cause wind speed everywhere in tunnel to differ, tunnel each
Speed difference is created on section.According to mechanics of viscous fluids principle, when there is speed difference when between LAYER FLUID, they it
Between will produce fluid shearing, thus forming vortex.Due to the acceleration of vortex, make internal fluid that rupture and rotation to occur, thus
Carry coal dust with great speed to external diffusion, cause most of dust-contained airflow can not enter exhaust fan and purified,
Severely impact the reduction of driving face Dust Concentration.
In sum, still there is no a kind of impact by conversion draft type, the distinguished and admirable vortex of elimination, thus having in prior art
Effect improves the equipment of driving face dust removing effects.
Content of the invention
In order that the distinguished and admirable formula blower fan that is largely drawn out of of the dust-laden of driving face sucks purification, thus effectively reducing
