Description
Technical field
The present invention relates to a kind of air discharging device, a kind of can the air discharging device of firedamp drainage, belong to mine safety device field.
Background technology
The places such as colliery, tunnel, subway engineering, local, down-hole need to set up ventilating engineering, particularly in needs often discharge
In the coal mine roadway of gas, the most commonly used mode is to utilize ventilation blower to connect positive pressure wind pipe to be aerated, when needs discharge
During gas, be typically all use restriction be blown into tunnel air quantity or use three way type positive pressure wind pipe release, control at mixing watt
This concentration.And during practice of construction, the positive pressure wind pipe being made with rubber coated cloth the highest often leaks due to pressure
Wind needs often to change, indirectly improve cost；And Boiler pressure control is unstable, gas density does not reaches the standard of regulation, warp
Often need human intervention, constantly adjust, it is impossible to reach firedamp drainage with security and stability, ensure staff's life security under ore deposit
Purpose.
Summary of the invention
The problem existed for above-mentioned prior art, it is an object of the invention to provide a kind of pressure height, can avoid ventilation process
In air leakage phenomena, readily and stably control air quantity, accurate control gas concentration, it is ensured that gas safety discharge and human life
Safety, it is possible to achieve cost efficiency can the air discharging device of firedamp drainage.
For achieving the above object, the technical solution used in the present invention is: a kind of can the air discharging device of firedamp drainage, including metal wind
Cylinder, the end surface that described metal air duct is connected with ventilation blower is provided with air door, and described air door is formed around sealing ring, and air door
Overlying is covered with cover plate, and cover plate is flexibly connected with metal air duct, and cover plate is connected to outside metal air duct by adjustable connecting rod
Surface, is connected by the internal wind deflector arranged of connector and metal air duct inside cover plate.
Preferably, described metal air duct be diameter 800mm, the iron sheet cylinder of length 1500mm.
Preferably, described wind deflector is the plectane of diameter 600mm.
Preferably, described adjustable connecting rod is flower basket bolt, and described flower basket bolt one end is located on the connection ring outside cover plate,
The other end is hinged on metal air duct outer surface.
The present invention uses hard material, resistive pressure, and air door airtight performance is good, can be prevented effectively from ventilation process through test
In air leakage phenomena, reduce change and maintenance frequency；The office of the gas density regulation ventilation blower can discharged according to tunnel
Portion's air quantity, adjustable connecting rod can arbitrarily adjust the angle of wind deflector according to gas density, it is possible to makes wind deflector position stable,
Thus keep air quantity stable, it is finally reached the purpose of safety dumping gas, it is ensured that human life's safety, it is not necessary to see in real time
Protect, saved cost, improve economic benefit.

Detailed description of the invention
Below in conjunction with the accompanying drawings the present invention is described in further detail.
As shown in Figure 1 can the air discharging device of firedamp drainage, including metal air duct 10, described metal air duct 10 is connected with ventilation blower
End surface be provided with air door 11, described air door 11 is formed around sealing ring, and air door 11 overlying is covered with cover plate 20, lid
Plate 20 is flexibly connected with metal air duct 10, and cover plate 20 is connected to metal air duct 10 outer surface by adjustable connecting rod 21,
It is connected by the internal wind deflector 30 arranged of connector 40 and metal air duct 10 inside cover plate 20.
Preferably, in order to ensure compressive resistance, ensureing ventilation effect, described metal air duct 10 is diameter 800mm, length simultaneously
The iron sheet cylinder of degree 1500mm.
Preferably, in order to preferably unload wind and control air quantity, the effect of guarantee firedamp drainage, described wind deflector 30 is diameter 600mm
Hard plectane.
Preferably, in order to make regulation convenient, described adjustable connecting rod 21 is flower basket bolt, described flower basket bolt one end
Being located on the connection ring 22 outside cover plate 20, the other end is hinged on metal air duct 10 outer surface.
During use, one end closer for present invention distance air door 11 is exported compact siro spinning technology with ventilation blower, opens ventilation blower, just
During normal open wind, as shown in Figure 4, cover plate 20 covers on air door 11, and ventilation blower i.e. carries air by air discharging device in tunnel
