Temporary Ventilation or exhaust need far firing range blower, conventional range in tunnel, mine or the longer channel of depth
Remote blower is directly proportional to the power of blower and volume, but there is also because capacity issue can not dispose or fail to lay down or be not placed into
The problem of, blower small in size can only be selected in practice, but be greatly reduced range and ventilation effect simultaneously, for this purpose, also needing
Want a kind of blower convenient for connecting according to simultaneously energy multi-stage booster.
Utility model content
The purpose of the utility model is to overcome above-mentioned the deficiencies in the prior art, provide a kind of multi-staged booster fan, including
Blower one, blower two and the blower three of tandem connection, set fan one, a left side for level-one air inlet duct in the level-one air inlet duct of blower one
End sets connection seam allowance one, and fan two, connection step one and the blower one of blower two are set in the taper pressurization air duct one of blower two
Excircle sets fixed ring and fixes after the connection embedded connection of seam allowance one, sets fan three, wind in the taper pressurization air duct two of blower three
The connection step two of machine three sets fixed ring with excircle after the embedded connection of connection seam allowance two of blower two and fixes, tandem connection
The taper that taper pressurization air duct one afterwards is integrally formed with taper pressurization air duct two is pressurized air duct, and the utility model is multistage blower
It is composed in series, fan one is sent into air-flow after the sucking of level-one air inlet duct after the compression pressurization of taper pressurization air duct and is sent from exhaust passage
Out, air-flow is fan forced by more than one piece simultaneously when taper pressurization air duct is compressed, and greatly improves wind pressure and jet stream, and enhance air-flow
Stability.
In order to achieve the above objectives, the utility model provides a kind of multi-staged booster fan, including tandem connection blower one,
Blower two and blower three set fan one in the level-one air inlet duct of the blower one, and the left end of the level-one air inlet duct sets connection and stops
Mouth one, the taper of the blower two, which is pressurized in air duct one, sets fan two, and the path left end in taper pressurization air duct one sets connection seam allowance
Two, two right end peripheral hardware of blower connects step one, and the connection step one is consolidated with connecting excircle after the embedded connection of seam allowance one and set
To determine ring to fix, sets fan three in the taper pressurization air duct two of the blower three, the path that taper is pressurized air duct two is connected to exhaust passage,
Three right end peripheral hardware of blower connect step two, the connection step two with connect the embedded connection of seam allowance two after excircle set fixed ring
Fixed, the taper that the taper pressurization air duct one after tandem connection is integrally formed with taper pressurization air duct two is pressurized air duct.
Further setting, the taper pressurization air duct bigger diameter end are smoothly connected with level-one air inlet duct.
The beneficial effects of the utility model are: the utility model is multistage fans in series composition, fan one is air-flow from one
It is sent out after being sent into the compression pressurization of taper pressurization air duct after grade air inlet duct sucking from exhaust passage, air-flow is when taper pressurization air duct is compressed
It is fan forced by more than one piece simultaneously, wind pressure and jet stream are greatly improved, and enhance the stability of air-flow.
