Novel self-rotating aeration device

The invention discloses a novel self-rotating aeration device. The device comprises a shell and an inverted-umbrella-shaped impeller arranged in the shell. A net-shaped bubble breaking device is arranged under the inverted-umbrella-shaped impeller; an air outlet device is arranged under the net-shaped bubble breaking device. The inverted-umbrella-shaped impeller, the net-shaped bubble breaking device and the air outlet device are connected through a connecting rod, the interior of the connecting rod is hollow, the air outlet device is communicated with the interior of the connecting rod, an air inlet pipe with a diameter smaller than the inner diameter of the connecting rod is led into the lower portion of the connecting rod, and air outlet holes are evenly distributed in the air inlet pipe. The aeration device rotates by means of the counter-acting force of bubbles coming out of the aeration holes; under the action of centrifugal force, the upper water body is lifted and thrown to theperiphery along the arc-
