PURPOSE:To prevent the decrease in a stirring effect of a gas for a liquid by forming a stirring shaft and an impeller into the shape which generates the centrifugal force to move the foams sticking to the stirring shaft and the impeller toward the side of the vanes provided to the tip of the impeller. CONSTITUTION:A stirring shaft 12 and an impeller 14 are formed into the shape which generates the centrifugal force to move the foams sticking to the shaft 12 and the impeller 14 to the side of vanes 13 in a device which stirs and mixes a highly viscous liquid and gas with the impeller 14 provided to the shaft 12 and provided with the vanes 13 at the tip. After the foams sticking to the shaft 12 and the impeller 14 is moved to the vane 13 side, the foams are dispersed by the vanes 13, by which the decrease in the gas-liquid stirring effect is prevented, the time for stirring and mixing is reduced and the consumption of the gas is reduced. |
