Abstract
A centrifugal wind wheel with an improved flow guide ring and a blade plate comprises the flow guide ring, a fan blade and a blade plate, wherein the flow guide ring is provided with a flow guide port; the fan blade is welded with the flow guide ring; the surface for the welding of the flow guide ring and the fan blade is a welding side; the fan blade and the blade plate are integrally formed and made; and the surface for the connection of the blade plate and the fan blade is a connecting side. The centrifugal wind wheel also comprises an air expansion device arranged on an outlet formed by the flow guide ring and the blade plate. With the structure and the air expansion device, the outlet is correspondingly enlarged and the aim of pressure expanding is achieved. The flow loss of gas is reduced, and the efficiency of the fan blade is improved.
