Abstract
Abstract A liquid moving and mixing apparatus is selectively submersible in a body of liquid and is operative to effect a turbulent flow of the liquid upwardly and then outwardly and then downwardly and to mix a selected material into the body of liquid during the upwardly and outwardly flow of the liquid. The liquid moving and mixing apparatus includes a propeller rotated by a submersible motor carried on a portion of a frame structure extending upwardly from a ballast member. The propeller directs the flow of liquid upwardly toward a downwardly directed apex of a cone-shaped diffusing member which directs the flow upwardly and outwardly toward a deflector member which deflects the flow outwardly and downwardly. Liquid flow by the diffusing member cooperates with and/or induces a flow of a selected material outwardly through an annular orifice in the diffusing member adjacent to and spaced from the apex thereof to mix said material into the body of liquid during the flow effected therein.
