PURPOSE:To obtain a stirring blade adaptable to various applicational conditions and capable of exhibiting excellent stirring capability with a camparatively small power by providing an auxiliary fin by which the direction of discharge flow is regulated in radial direction to the body of axial flow blade. CONSTITUTION:An auxiliary fin 3 is integrally provided to the tip of each main blade 2 of an axial flow type stirring blade body 1 of a fan turbine type with an angle. The fin 3 is made into an inversed T-shape consisting of a rectangular and flat plate-like base fin 4 and a rising fin 5 vertically rising upwards from the central part of the base fin 4. And, the fin 4 is positioned on an imaginary horizontal flat face crossing at a right angle to the rotary axis Y of the blade and welted to the tip of each plate 2. Since the stirring blade is provided with an auxiliary control fin by which to regulate the direction of discharge flow toward radial direction, provided to the axial flow type blade body, by adjusting properly the size and angle of the auxiliary fin, strong discharge flow directed more in radial direction than in the case of the conventional axial flow type stirring blade can be obtained. |
