PURPOSE:To obtain a moving type stirrer with efficient stirring effect even when it is used in a tank of an extremely low liquid level by completely surrounding the periphery of the side portion of a rotary blade and an under-water motor with a liquid-casing to form a path for a liquid to be stirred. CONSTITUTION:Not only the side periphery of the rotary blade 6 but also the side periphery of the under-water motor 2 are surrounded completely with the liquid suction casing 3 to form the liquid path 7. Thus, even when the liquid level in the stirred tank 5 is in an extremely low level close to the tank bottom, the cooling of the under-water motor 2 is made possible by switching the flow of liquid to an upward flow. Thus, the stirrer 1 can be continuously used. |
