IMPELLER OF CENTRIPETAL BLOWER Russian patent published in 2009 - IPC F04D29/28 

FIELD: ventilation.

SUBSTANCE: invention is in the field of air blower construction and can be used in agriculture when cooling grain. The impeller of centripetal blower comprises a hub and cover plates and through-shaped curved moving blades mounted in between them. The ends of trailing edges of the blade are straight and connected by gradient junction to the cone form lug fixed by the base of the hub plate.

EFFECT: this provides steadier and more perfect air intake by blades, uniform direction of air flow and allows smoother and full operating air-out ventilation through the lug for subsequent operation, which allows energy cost reduction, loss minimisation and increase in efficiency.
