PURPOSE: An aerating apparatus is provided to increase the mixing rate of air and water by radially emitting air into water in a mixing part equipped with an impeller and applying the torque of the impeller into the water mixed with the air. CONSTITUTION: An aerating apparatus includes a casing(100), a mixing part(200), an impeller, a sucking housing(500), and an air introducing part(600). The casing is arranged in water, and a motor is embedded in the casing. An outlet is formed at the mixing part, and the driving shaft of the motor penetrates from the rear side to the front side of the mixing part. The impeller is rotatably installed in the mixing part. The impeller is combined with the driving shaft. The sucking housing is installed at the front side of the mixing part, and the rear side of the sucking housing is opened. A plurality of sucking holes(510) is formed at the sucking housing. The air introducing part penetrates from the front side to the rear side of the sucking housing. External air is introduced toward the impeller by the air introducing part. |
