Description
Technical field
Blower fan technical field is the utility model is related to, specially a kind of axial-flow type 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 to provide a kind of axial-flow type smoke exhaust fan, and fire-proof high-temperature resistant ability is strong, operation
Noise is small, and the ventilation of specific energy consumption is big.
To achieve the above object, the utility model provides following technical scheme：A kind of axial-flow type smoke exhaust fan, including
Shell with air inlet and air outlet, enclosure are provided with impeller mechanism and middle cylinder, and the impeller mechanism includes impeller, installation
In blade and motor on impeller, the middle cylinder is closing barrel structure, and middle cylinder is provided with blast pipe and discharge pipe, the motor peace
Inside middle cylinder, the output end of motor is connected with impeller, and the tail end of motor is additionally provided with tail wheel, and the middle cylinder is by thermal insulation layer and heat
Rolled steel plate forms, and the thermal insulation layer is glass-fiber reinforced thermoplastic plastic layer；The shell by hot rolled steel plate and damping every
Sound-absorbing layer forms, and the damping puigging is polyurethane foam board.By setting glass-fiber reinforced thermoplastic plastic layer to show
The fire-proof and thermal-insulation ability of cylinder in improving is write, heat heating of the motor in the scene of a fire is reduced, extends the ventilation smoke exhaust time.It has simultaneously
The polyurethane foam board collective effect of anti-acoustic capability and shell, it can make to keep low noise operation in the ventilation under normality.
Further, the thermal insulation layer is honeycomb.
Further, the position face tail wheel of the blast pipe, discharge pipe are located away from tail wheel.Entered by blast pipe
The heat of the motor of taking of the transmission energy large area of the cooling wind of middle cylinder.
Further, the section distortion angle of the blade is 48 °.By changing the section distortion angle of blade by tradition
60 ° of adjustment, main region do work to air of optimization blade, the discharge coefficient and pressure coefficient for making blade increase, be applied to
Being done work when in pipe ventilated in same consumption energy, ability is stronger, discharge capacity is bigger.
Further, the air inlet of the shell is provided with protective cover, and the protective cover is secured by bolts on shell, prevents
It is conical through-hole in the middle part of shield, filter screen is set in conical through-hole, the filter screen is installed on conical through-hole by spacing bulb plunger
On inwall.Set protective cover to avoid sucking some debris influence ventilation and heat while strengthening exhaust air rate, pass through spacing bulb
Plunger is fixedly connected, and makes fixed and dismounting more convenient.
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, sets by using the thermal insulation board of middle cylinder and can slow down heat transfer, in the case where cooling down wind action to blower fan
Cooling is aerated, extends the run time of blower fan, the design to leaf curling angle makes it be more suitable for the operation of long pipeline, carries
Ventilation in its high specific energy consumption, so as to improve the fire-fighting of smoke exhaust fan effect；And under normal conditions, thermal insulation board and shell disappear
Sound noise reduction capability then makes the operation of blower fan more steady, reduces problem of noise pollution caused by mechanical oscillation and air vibration.
