The powerful blower fan of system motor type comprises the shell that is provided with intake grill and exhaust outlet in the axial flow of whirlpool, by first supporting part stationary axle is installed in the shell, stationary axle is provided with motor stator, stationary axle is provided with second supporting part of tubular, the two ends of second supporting part cooperate with the stationary axle rotation, be provided with centrifugal impeller in end near second supporting part of intake grill, the inwall of the barrel of second supporting part is provided with the rotor corresponding with motor stator, the outer wall of the barrel of second supporting part is provided with first blade of some annular distribution, at the inwall of shell and first sharf to corresponding second blade that is provided with, at the inwall of shell radially corresponding with centrifugal impeller and with first sharf to corresponding the 3rd blade that is provided with.
Also can not establish rotor and motor stator in the structure among the present invention, utilize peripheral hardware driven by motor second supporting part can reach identical effect equally.
Hub disk that described second supporting part comprises its centrifugal impeller of installing near intake grill end, install near the exhaust outlet end and the barrel that is combined into by some ring bodies between centrifugal impeller, hub disk;
Cylindrical shell that described shell is combined into by some ring bodies and front cover and back cover are formed, and intake grill is located on the front cover, and exhaust outlet is located on the back cover;
End by intake grill on the described stationary axle is provided with the rectification head;
Described first, second, third blade is an arc.
The present invention for centrifugal and axial fan be integrated, with its functional part impeller and as a kind of blower fan of motor body structural member.This blower fan reduces greatly than blower fan weight, volume, the energy consumption of identical output wind-force, eliminated the feasible installation of middle transmission link very easy (need not adjustment center or level) again, have the advantage of big air quantity and high blast, or have higher negative blast and bigger degree of vacuum.It is the blower fan kind of an innovation.The suction that can be applicable to harbour grain, ore in sand form, fine coal etc. is sent, also can be in industry-by-industry extensive uses such as metallurgy, chemical industry.
Below in conjunction with drawings and Examples the present invention is further specified.
