To achieve the above object, the utility model provides the following technical solutions:A kind of quick release large fan noise reduction One end of device, including casing, the casing offers air inlet, and is connected with import by flange seal on air inlet and eliminates the noise Device, the described one end of import silencer far from air inlet are fixed with blast pipe, and close to the one of import silencer inside blast pipe End is equipped with filter screen, air outlet is offered on the casing, and outlet noise silencer is equipped on air outlet, the bottom of shell Supporting rack there are two being fixed at a side position of air outlet, and two supporting racks are in splayed structure.
Preferably, the inside of the casing is equipped with impeller sets, and the both ends of impeller sets rotate with the inner wall of casing and connect It connects.
Preferably, the impeller sets include eight airfoil vanes, and eight airfoil vanes circular arrays are distributed.
Preferably, the one end of the casing far from air inlet is connected with oil cooling bearing housing, and oil cooling bearing housing is far from casing Be fixed with shaft coupling.
Preferably, the shaft coupling is rotatablely connected with impeller sets by shaft close to one end of oil cooling bearing housing, and shaft coupling The one end of device far from oil cooling bearing housing is rotatably connected to motor, and the motor is electrically connected with external power supply.
Compared with prior art, the utility model has the beneficial effects that:
(1)The utility model is respectively provided with import silencer and outlet noise silencer at air inlet and air outlet, and into Respectively with air inlet and air outlet by flanged joint, the import silencer of setting and outlet disappear for mouth silencer and outlet noise silencer Sound device is dissipative muffler, not only contributes to the air power noise for reducing inlet, outlet radiation, and easy to disassemble, In addition, being provided with filter screen also in blast pipe, be conducive to prevent impurity from entering import silencer, be conducive to that import is protected to eliminate the noise Device.
(2)Traditional common blade is changed to airfoil vanes by the utility model, advantageous by the blade streamline of airfoil vanes In improving acoustical behavior the anti-acoustic capability of wind turbine is substantially increased to realize control noise source.
