ABSTRACT:
A submersible mixer apparatus for circulating liquid in a body of water, such as a sewage lagoon, includes an upright beam member closed to form an air reservoir chamber and upper and lower supports holding the beam member in the body of liquid. A submersible motor and propeller are connected to the beam member by a bracket movable up and down on the beam member and a square tubular support arm affixed to the bracket and to which the submersible motor and propeller are mounted. The support arm is hollow and pressurized air is routed through the upright beam member and the support arm to an outlet of the support arm positioned substantially at the propeller to inject air into the flow area created by the propeller. A selectively engageable and disengageable connector arrangement is positioned between the upright beam member and the support arm which, when engaged, routes the air from the upright beam member into the support arm.
