ABSTRACT:
An aspirating horizontal mixer for aerating and liquid mixing includes a float with tiltable supports extending downwardly into a body of water and an air delivery conduit which are connected to a mixer unit supported below the liquid surface by the supports and tiltable therewith. The mixer unit includes a submersible motor powering a propeller and a nozzle member situated in the flow path of liquid from the propeller. The nozzle member has an internal venturi for mixing air from the air delivery conduit with the liquid flowing therethrough and includes a converging wall formation forming a constriction and a diverging wall formation leading downstream and merging with the interior wall of the nozzle member. An air injection port extends through the diverging wall formation adjacent the constriction and is in communication with the air delivery conduit for mixing air with the liquid as it flows through the venturi.
