Description
Technical field
The present invention relates to ventilation equipment technical field, more particularly to a kind of noise cancelling type fire-fighting high temperature
Smoke discharging axial fan.
Background technology
Modern architecture thing is generally provided with fire-fighting smoke exhaust system, and the system is main by induction installation
Several parts such as control device smoke duct and smoke exhaust fan constitute, and the function of fire-fighting smoke exhaust system is
When fire occurs, the dense smoke produced by strength discharge combustible burning, to reduce fire as far as possible
Calamity scene delay personnel suffocate caused by dense smoke, and loses escape chance.And noise cancelling type fire-fighting is high
Warm smoke discharging axial fan is the core component of fire-fighting smoke exhaust system, but existing blower fan has noise
Greatly, the problem of motor shaft end weak heat-dissipating, causes noise pollution to resident family in use,
User's request can not be fully met.
The content of the invention
To overcome above-mentioned deficiency, the invention provides a kind of sound deadening shock absorption effect it is good, radiate it is high
Noise cancelling type fire-fighting high-temperature smoke discharging axial fan.
The technical solution adopted by the present invention is：A kind of noise cancelling type fire-fighting high-temperature smoke discharging axial fan,
Including the blower fan outer barrel being made up of air inlet and blower housing, it is arranged in blower fan outer barrel
Impeller and motor, outside motor are provided with inner cylinder, and inner cylinder is connected by flange with blower fan outer barrel,
The blower housing side is provided with air admission hole, is provided with venthole on inner cylinder, air admission hole with go out
Stomata is connected by pipeline, and the rear end of the motor is provided with cooling wheel, the blower fan outer barrel
Air inlet and inner cylinder inwall on be provided with deadener layer.
As the further setting of above-metioned scheme, the material of the deadener layer is ultra micro orifice plate
Material.
As the further setting of above-metioned scheme, the length of the air inlet of the blower fan outer barrel is wind
The half of machine shell.
As the further setting of above-metioned scheme, it is provided with bullet between the blower fan outer barrel and impeller
Property bed course.
As the further setting of above-metioned scheme, lead between the air inlet and blower housing
Cross bolt connection.
The length of the air inlet of blower fan outer barrel of the invention is the half of blower housing, and outside blower fan
Elastic insert is provided between cylinder and impeller, on the air inlet of blower fan outer barrel and the inwall of inner cylinder
Deadener layer is provided with, raising blower fan effect is served being prevented effectively from while surge occurs
Rate, the purpose for reducing noise.The noise cancelling type fire-fighting high-temperature smoke discharging axial fan not only sound deadening shock absorption
Effect is good, and effectively improves the radiating of motor.

Specific embodiment
Below in conjunction with the accompanying drawings and embodiment is described further to the present invention.
As shown in figure 1, a kind of noise cancelling type fire-fighting high-temperature smoke discharging axial fan, including entered by blower fan
Air port 11 and the blower fan outer barrel 1 of the composition of blower housing 12, are arranged on the leaf in blower fan outer barrel 1
Wheel 2 and motor 3, are provided with inner cylinder 4 outside motor 3, inner cylinder 4 passes through flange 5 and blower fan
Outer barrel 1 is connected, and the side of the blower housing 12 is provided with air admission hole 6, is set on inner cylinder 4
There is venthole 7, air admission hole 6 is connected with venthole 7 by pipeline, the rear end of the motor 3
Cooling wheel 31 is installed, on the air inlet 11 of the blower fan outer barrel 1 and the inwall of inner cylinder 4
Deadener layer 8 is provided with, the material of the deadener layer 8 is ultra micro orifice plate material,
The length of the air inlet 11 of the blower fan outer barrel 1 is the half of blower housing 12, the blower fan
Elastic insert 9, the air inlet 11 and blower fan are provided between outer barrel 1 and impeller 2
Connected by bolt 10 between shell 12.
During present invention work, the cooling wheel 31 that the rear end of motor 3 is installed is operated, and air is from blower fan
The air admission hole 6 that the side of shell 12 is set, the venthole 7 set on inner cylinder 4 is entered by pipeline,
Then discharged from air outlet, motor 3 is cooled down, improve the radiating of motor 3；Simultaneously
The length of the air inlet 11 of blower fan outer barrel 1 is the half of blower housing 12, and blower fan outer barrel 1
Elastic insert 9, the air inlet 11 and inner cylinder 4 of blower fan outer barrel 1 are provided between impeller 2
Inwall on be provided with deadener layer 8, be prevented effectively from surge occur while serve
Improve fan efficiency, reduce the purpose of noise.
