Liquid moving and mixing apparatus

A liquid mixing apparatus comprising:

• a. a ballast member;
• b. a frame structure mounted on said ballast member and extending upwardly therefrom and having an upper end portion;
• c. a submersible motor mounted on said frame structure and positioned adjacent the upper end portion thereof;
• d. a propeller rotated by said submersible motor to effect an upwardly directed flow in a body of liquid;
• e. a diffusing member mounted on said frame structure and positioned above said propeller, said diffusing member having a fluid receiving chamber therein, said diffusing member being cone-shaped to diffuse the flow upwardly and outwardly;
• f. means for communicating to the fluid receiving chamber within said diffusing member a supply of fluid to be mixed into the body of liquid;
• and
• g. means on said diffusing member for defining an annular orifice surrounding said diffusing member and means communicating between the fluid receiving chamber of said diffusing member and the annular orifice for flow of fluid therebetween and outwardly through said annular orifice in response to the upwardly flow effected by said propeller whereby the fluid is mixed with the liquid in the body of liquid.

A mixing apparatus for mixing treating materials into liquid of a body of liquid, said mixing apparatus comprising:

• a. a liquid flow diffuser having a wall defining an inverted cone with an apex;
• b. means in said diffuser defining a treating material chamber therein adjacent the apex, said diffuser wall having a plurality of apertures adjacent said apex and communicating with said chamber;
• c. a cone-shaped cap member secured to said diffuser in surrounding relation to the apex thereof and having a wall spaced from the wall of said diffuser and extending above said apertures to define an annular venturi passage between said diffuser and said cap member, the venturi passage terminating in an annular venturi opening;
• d. a submersible motor and a propeller driven thereby;
• e. means supporting said motor and propeller below and in axial relation to said diffuser to effect a liquid flow past the annular venturi opening to draw treating material from said chamber into the liquid flow;
• and
• f. means positioning said diffuser and motor in a body of liquid below the surface thereof.
