Technical Field
The utility model relates to an axial fan falls the technical field of making an uproar, especially relates to an explosion-proof low noise axial fan.
Background
The axial flow fan has a very wide application, namely, the axial flow fan and the fan blade have the same direction of air flow, such as an electric fan, and an air conditioner outer machine fan is an axial flow type running fan. The "axial flow" is so called because the gas flows parallel to the fan axis. Axial flow fans are typically used in applications where flow requirements are high and pressure requirements are low. The axial flow fan is fixed in position and moves air, and a general axial flow fan can be used for ventilation in places such as general factories, warehouses, offices, houses, and the like, and can also be used for air coolers (air coolers), evaporators, condensers, sprays, and the like.
The noise is the sound which causes the dysphoria of people or the sound volume is too strong and harms the human health, all the sound which hinders people to have a rest, study and work normally and the sound which interferes with the sound to be heard by people belong to the noise, the axial flow fan has the defects of high noise, small wind pressure and wind volume, the power of a motor must be increased and the size of an impeller must be increased to obtain high wind pressure and wind volume, so the manufacturing cost of a common axial flow fan is high, the power consumption is large, the axial flow fan is not beneficial to environmental protection and energy saving, meanwhile, the chemical compositions of different working occasion gases are complex, the axial flow fan can generate flammable and explosive harmful gases under certain conditions, and at the moment, the impeller rotates and is easy to explode, so the.
SUMMERY OF THE UTILITY MODEL
The utility model aims at overcoming present axial fan at the during operation, the noise of production is bigger, influences the not enough of the individual work of people's normal rest, and the explosion-proof low noise axial fan who provides.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
the utility model provides an explosion-proof low noise axial fan, includes the base, install the fan main part on the base, be equipped with the preceding stator on the baffle in the fan main part, install the motor in the fan main part, the output shaft end of motor is fixed with the impeller, install the diffusion section of thick bamboo in the fan main part, install a plurality of back stator on the diffusion section of thick bamboo, and the diffusion section of thick bamboo all corresponds the setting with the impeller with the back stator, be equipped with the inlet end silencer on the front end lateral wall of fan main part, be equipped with the export silencer on the rear end lateral wall of fan main part.
Preferably, an air outlet is formed in the side wall of one end of the fan main body, and a connecting cylinder is connected to the air outlet.
Preferably, an air inlet is arranged on the side wall of one end of the fan main body, and an inlet collector is connected to the air inlet.
Preferably, the impeller is made of an aluminum alloy material.
Compared with the prior art, the beneficial effects of the utility model are that:
the utility model discloses import and the export of fan set up inlet end silencer and export silencer respectively, because prepare sound absorbing material in the silencer, the frequency of sound wave has been changed, thereby played the effect of noise reduction, and set up the baffle, preceding stator and back stator, it is more steady when making the air current flow, prevent that the gas flow is disorderly, the noise of production is great, thereby influence people's normal life, and the impeller adopts aluminium alloy material, the during operation does not produce the electric spark, play the blast proof effect.
