Embodiment
As Fig. 4, shown in Fig. 5, a kind of pneumatic without blade fan for mine, the annular nozzle 1 that this fan at least comprises pedestal 8 and is supported on pedestal 8, annular nozzle 1 inside has annular channel 7, annular nozzle 1 inwall has the annular exhaust slit 2 being communicated with annular channel 7 and annular nozzle endoporus 3, be provided with in pedestal 8 for purify air and control air pressure and flow air treatment module 9 and for the conducting air puocessing module 9 air guide joint 6 with annular channel 7, wherein air treatment module 9 has suction port 90 for connecting airduct 10 and the air outlet 99 for being connected air guide joint 6 one end, air guide joint 6 the other end connects annular nozzle 1.
The high-pressure air source utilizing mine conventional as driving force to annular channel 7 inner ventilation, during use, need the suction port 90 first connecting airduct 10 and air treatment module 9, stop valve 20 can be connected between airduct 10 and the suction port 90 of air treatment module 9, open stop valve 20, pressurized gas in airduct 10 just can pass in air treatment module 9, dry without blade fan, close stop valve 20, blowing is stopped without blade fan, stop valve 20 plays the effect of switch, also maintain easily maintenance simultaneously, pressurized gas carry out purifying and through its air outlet 99 through air treatment module 9, air guide joint 6 enters in annular channel 7, high pressure draught is sprayed through annular exhaust slit 2, high pressure draught can drive its ambient air flow forward together in swiftly flowing process, thus form negative pressure at annular nozzle 1 rear, under under atmospheric pressure effect, intake velocity is strengthened, such wind without blade fan is just exaggerated, can to the greasy dirt in air by air treatment module 9, steam and dust granule filter, reach anti-flaming effect, by air treatment module 9, control is carried out to the air pressure and flow that pass into air and play explosion-proof effect, thus make improvedly can be controlledly safely used in the inflammable and explosive environment of mine without blade fan.
As the embodiment of above-described embodiment, air treatment module 9 is made up of the pressure controlled valve 91 connected by pipeline, oil and water seperator 92 and flow control valve 93.Pressure controlled valve 91 is for the stable air pressure entered in annular channel 7, prevent that pressure is excessive causes explosion, oil and water seperator 92 is for filtering the greasy dirt in the gas passed in annular channel 7 through airduct 10, steam and dust granule, prevent from these compositions from causing with gas and vapor permeation such as the gas of mine in a high voltage state to fire, flow control valve 93 enters the air mass flow in annular channel 7 for controlling, and controls air quantity.Air treatment module also can combine the process such as the Stress control to source of the gas and the moisture content to source of the gas, greasy dirt, particle by other pneumatic element.
In order to strengthen the water conservancy diversion effect of air guide joint, air guide joint 6 is in funnel-like, one end that its medium caliber is less connects air treatment module air outlet 99 (being flow control valve outlet port in this embodiment), and one end that bore is larger and annular nozzle 1 are tightly connected.
In order to strengthen cooling effect further, annular nozzle 1 endoporus is along its axis X ' direction is horn-like, as shown in Figure 5, annular exhaust slit 2 is located at the less one end 12 of annular nozzle endoporus 3 bore and comparatively small end 12 to bore larger end 11 direction (i.e. X ' direction) and annular nozzle inner hole wall 30 are tangent along annular nozzle endoporus 3 bore.Like this, water conservancy diversion is carried out to distinguished and admirable by annular nozzle inner hole wall 30, make air-flow and annular nozzle inner hole wall through annular exhaust slit ejection tangent and spray from larger end 11 high speed of annular nozzle endoporus bore, the high velocity air of ejection drives its ambient air thereupon together along axis X ' direction flowing, such meeting forms negative pressure near annular nozzle endoporus 3 bore comparatively small end 12, owing to there is pressure reduction with atmospheric pressure, annular nozzle endoporus 3 bore is made to accelerate to flow in annular nozzle endoporus 3 compared with the air at small end 12 rear, the gas flow finally passed into from the relative airduct of air of annular nozzle endoporus 3 bore larger end 11 ejection can increase by tens times, range can reach tens meters.
Last it is noted that above each embodiment is only in order to illustrate technological scheme of the present invention, be not intended to limit; Although with reference to foregoing embodiments to invention has been detailed description, those of ordinary skill in the art is to be understood that: it still can be modified to the technological scheme described in foregoing embodiments, or carries out equivalent replacement to wherein some or all of technical characteristics; And these amendments or replacement, do not make the essence of appropriate technical solution depart from the scope of various embodiments of the present invention technological scheme.
