Background technology
The utility model relates to a kind of device for reducing dust that reduces colliery gun diging face dust, can effectively reduce various coal dusts, rock dirt that development end produces.
At present, dust still is one of subject matter of puzzlement Coal Production, and the dust of high concentration especially respirable dust is the immediate cause of bringing out workman's pneumoconiosis, therefore reduces dust concentration, especially the concentration of respirable dust is very necessary, also is a major technology difficult problem.In recent years, the gun diging face measurements for reduction mainly is a watering and lowering dust, and its mechanism is that grit and droplet constantly bump, wetting, cohesion, weightening finish and constantly sedimentation.But the hydraulic pressure of most mines is difficult to the dust-laying effect that reaches desirable.The electronic automatic sprayer of blasting of producing on the domestic market at present exists high prominent gaseous mine to blow out the out of use problem that must have a power failure, and can not realize blowing out auto spraying, reduces coal dust and prevents the problem that the accident of blowing out takes place.
Summary of the invention
To blow out and spray synchronously, increase spray effect, reduce the technical barrier that the accident of blowing out takes place in order to solve, the present invention adopts mechanical auto spraying, in order to increase the rally that contacts of water and dust, good fit by pressure wind and press water makes the depositing dust aqueous vaporization.Thereby reach depositing dust, eliminate the flame when blowing out, realize the purpose of safety in production.
The technical scheme that its technical problem that solves the utility model adopts is: the automatic air water atomization mechanism of a kind of mechanical blasting, its composition comprises fixed axis, connection water pipe, horizontal depression bar, montant, spring, compressing ball, shift fork, the pressure water valve of quick connector, blast fence, the decorative pearl on top of an official cap, water mixing chamber, air valve, air water switch lever, nozzle sets, tracheae, arrow, switch lever, it is characterized in that: pressure wind is connected with quick connector, and air pulse reception baffle plate withstands the air pulse baffle plate by the decorative pearl on top of an official cap of upright support folder; Air cock is opened the back and is passed to air water hybrid chamber place by air pipe; Air valve is opened the back and is passed to water mixing chamber place by tracheae, after pressure water valve is opened, crosses the connection water pipe and passes to water mixing chamber place.; Laterally depression bar becomes the horizontal depression bar of cross structure with the air water switch lever, moves downward by horizontal depression bar, opens air valve, pressure water valve simultaneously; Spring in gas, the taps is depressed when being subjected to external force, makes gas, water form path, withstands the compressing ball when not needing work, and the path of pressure gas, water is shut; During the gas shock baffle plate, blast fence is washed upside down, become flat condition; Blast fence lower-left welding shift fork is depressed wind, air water switch lever, the air water switch lever is moved downward, by being fixed on two end-posts on the air water switch lever, montant on compressing wind, the taps moves downward, the compressing ball, pressure water valve, air valve are opened simultaneously, and press water, pressure wind enter sprayer hybrid chamber mixing directive simultaneously and blow out the place and reach the dirt that goes out, blow out gas, eliminate the purpose of flame.
The employing the beneficial effects of the utility model are: can effectively reduce the especially concentration of respirable dust of gun diging face dust concentration, can also prevent heading end methane accumulation by pressing wind that the high concentration gas that produces in the tunneling process is dispelled; Flame when elimination is blown out plays the effect of one-object-many-purposes.

The specific embodiment
Below in conjunction with accompanying drawing the utility model being done one describes in detail:
The automatic air water atomization mechanism of a kind of mechanical blasting, its composition comprise fixed axis, connection water pipe, horizontal depression bar, montant, spring, compressing ball, shift fork, the pressure water valve of quick connector, blast fence, the decorative pearl on top of an official cap, water mixing chamber, air valve, air water switch lever, nozzle sets, tracheae, arrow, switch lever.Wherein, pressure wind is connected with quick connector 1.Press water is connected with quick connector 2, and air pulse reception baffle plate 3 withstands blast fence by the decorative pearl on top of an official cap 4 of upright support folder.Air valve 6 is opened the back and is passed to water mixing chamber 5 places by tracheae 10, after pressure water valve 19 is opened, crosses connection water pipe 13 and passes to water mixing chamber 5 places.; Laterally the horizontal depression bar of depression bar 14 and 7 one-tenth cross structures of air water switch lever moves downward by horizontal depression bar 14, opens air valve 6 simultaneously, pressure water valve 19; Spring 16 in gas, the taps is depressed when being subjected to external force, makes gas, water form path, withstands compressing ball 17 when not needing work, and the path of pressure gas, water is shut.
When blowing out the impact air-flow impact air-flow baffle plate 3 that produces, air pulse baffle plate 3 is washed upside down, blast fence 3 becomes flat condition (figure-3 states) blast fence 3 lower-lefts welding shift fork 18 and depresses wind, air water switch lever 7, air water switch lever 7 is moved downward, by being fixed on two end-posts on the air water switch lever 7, compressing wind, montant 15 on the taps moves downward, compressing ball 17, make pressure water valve 19, air valve 6 is opened simultaneously, press water, pressure wind enters water mixing chamber 5 simultaneously to be mixed directive and blows out the place and reach the dirt that goes out, blow out gas, eliminate the purpose of flame.
Adopt the wind water mixed atomizing acting in conjunction, nozzle is fan-shaped layout, is installed in apart from the position of 3 meters of big gun work planes.In order to overcome the little problem of work plane hydraulic pressure, good fit by press water and pressure wind makes depositing dust hydraulic pressure form high-pressure gasified jet, directly sprays to blow out the place, and coal dust is eliminated the flame that produces when blowing out on the spot.Compressed-air system is a system of development end indispensability, adopts special geomantic omen nozzle, will press wind to act on the high-pressure fog water, and high pressure is distinguished and admirable can to improve droplet speed and density, has increased the length of jet eddy current section.Atomization mechanism adopts the fan-spray device, and the fan-spray device of front can cover driving face fully, effectively stops dust from flying, dust is eliminated produced the dirt place.
