Description
Technical field
Blower fan technical field is the utility model is related to, is specially a kind of supercharging smoke exhaust fan.
Background technology
Blower fan, which is widely used in the ventilation systems of heavy construction such as office block, industrial and mineral factory building, market, private residence, to be made
With, also can as purification air and adjust air corollary equipment.Current smoke exhaust fan is primarily present two in use
Individual problem, first, can produce the noise of larger decibel in running, to life, personnel have undesirable effect；Second, work as building
Interior generation fire, some Fan Equipments can not continuous firing at high temperature, the effect of fire control smoke exhausting can not be given full play to.
Utility model content
The purpose of this utility model is that providing one kind is pressurized smoke exhaust fan, and fire-proof high-temperature resistant ability is strong, and operation is made an uproar
Sound is small, and ventilation is big.
To achieve the above object, the utility model provides following technical scheme：One kind supercharging smoke exhaust fan, including tool
There is the shell of air inlet and air outlet, enclosure is provided with impeller mechanism and middle cylinder, and the impeller mechanism includes impeller, is installed on
Blade and motor on impeller, the middle cylinder are closing barrel structure, and middle cylinder is provided with blast pipe and discharge pipe, the motor installation
Inside middle cylinder, the output end of motor is connected with impeller, and air intake supercharging device, the air intake supercharging device bag are additionally provided with middle cylinder
Include the fan group in blast pipe, the drive being connected located at motor tail end with electric machine main shaft, the fan group and drive
Connected by spiral bevel gear group.Air intake supercharging device mainly increases the intake of blast pipe, the radiating of cylinder, wind in quickening
Fan group includes being fixed on the framework of blast pipe, the air draught blade on installation ground framework and rotating shaft.
Further, the spiral bevel gear includes the bevel pinion being connected located at fan group bottom with fan group, described
The periphery of drive is the bevel gear wheel for coordinating transmission with bevel pinion, is blade construction in the middle part of the drive.Motor operates
When drive bevel gear wheel to rotate, drive bevel pinion to rotate, bevel pinion makes fan group operating is quick to draw cylinder during cold wind enters,
Discharged by discharge pipe, to motor radiating；The blade construction of bevel gear wheel makes cooling wind quickly be conveyed in middle cylinder.
Further, one end of the nearly impeller of middle cylinder is tapered, reduces the resistance that the wind entered from air inlet is subject to, carries
High ventilation.
Further, the blast pipe is outside open-like shape.
Further, the middle cylinder is made up of thermal insulation layer and hot rolled steel plate, and the thermal insulation layer is glass-fiber reinforced heat
Thermoplastic layer；The shell is made up of hot rolled steel plate and damping puigging, and the damping puigging is polyurethane foam board.It is logical
The fire-proof and thermal-insulation ability for setting glass-fiber reinforced thermoplastic plastic layer to significantly improve middle cylinder is crossed, reduces motor in the scene of a fire
Heat heating, extend the ventilation smoke exhaust time.Its polyurethane foam board collective effect with anti-acoustic capability and shell simultaneously, can make
Low noise operation is kept in ventilation under normality.
Further, the thermal insulation layer is honeycomb.
Compared with prior art, the beneficial effects of the utility model are：Blower fan when needing smoke-discharging and ventilating when a fire
High power is transported, and discharges dense smoke, as the rise of environment temperature and motor rotate also next heat the rotation of motor can be made to tend to pole
Limit, is finally stopped rotation, by setting air intake supercharging device to improve the input of cooling wind in middle cylinder, makes the air-cooled speed of motor
Accelerate, promote electric motor temperature reduction to extend the duration of runs；The thermal insulation board of cylinder, which is set, in also further utilizing slows down heat transfer, centering cylinder
Windward side conical design reduce air intake be obstructed, improve its ventilation, so as to improve the fire-fighting of smoke exhaust fan effect；And in normality
Under, the sound-deadening and noise-reducing ability of thermal insulation board and shell then makes the operation of blower fan more steady, reduces mechanical oscillation and air vibration production
Raw problem of noise pollution.
