<p>Disclosed is an aeration apparatus which doubles an absorption force of air under the same power to absorb water filled in an inlet pipe where air flows in during an initial stage of starting without using extra means. The aeration apparatus comprises a hollow casing where a motor is installed; a mixing part installed on the front of the chasing, including a discharge hole in the radius direction, and having a driving shaft of the motor be extended to penetrate from the front to the back; an impeller installed in the mixing part to be rotated, and coupled with the driving shaft to generate movement in the radius direction of the mixing part; an absorption housing installed on the front side of the mixing part and forming multiple absorption holes; and an air inlet including an extended pipe which penetrates the absorption housing from the front to the back and is extended toward the impeller, and includes an auxiliary absorption part inserted into the inside of the extended pipe by being extended toward the front from the impeller and rotated with the impeller to providing an absorption force to a fluid inside the air inlet. Therefore, the aeration apparatus has an effect of efficiently performing aeration even in extensive depth by doubling absorption force of air under the same power to absorb water filled in the inlet pipe where air flows in during an initial stage of starting without using an extra means.</p> |
