Abstract

PURPOSE:To rapidly move water mixed with air and to widely aerate the water by providing an air chamber communicating with an impeller between the impeller and a submersible motor and using a leg for supporting the motor on the periphery of the impeller as a guide vane. CONSTITUTION:One end of an air supply pipe 15 is allowed to communicate with the air chamber 6 and the other end with the atmosphere through a flow control valve 16. The valve 16 is appropriately opened, the submersible motor 1 is driven, hence the water in the impeller 2 is moved toward the periphery of the impeller 2 to keep the impeller part at a negative pressure, air is introduced from the air supply pipe 15 through the valve 16, the air is mixed with water while agitating the water toward the periphery by the rotation of the impeller 2, and the mixture is discharged. The mixture is led to the outside along the supporting leg 8 as the guide vane at the time of the discharging, the water mixed with air is rapidly moved in a wide range, and aeration is widely and rapidly performed.
