Liquid mixing system for closed containers.

摘要

A mixing apparatus for use with a container (21) having a continuous side wall (22) substantially centered around and defining a longitudinal axis (A), the mixing apparatus (20) comprising: a base plate (25) which it can be removably mounted on top of the container (21); a table frame (50) that can be removably mounted on the base plate (25); a housing (42) that can be removably mounted on top of the table frame (50); a mixing head (30) comprising a generally annular blade body (32) for immersion in the fluids to be mixed within the container (21), the blade body (32) having a hub element (70) placed at the center defining a substantially vertical directed hub axis (B), said hub element (70) being fixed and surrounded by an annular portion (72) defining a hole (75) having a center of symmetry; a drive shaft (80) for supporting the mixing head (30) inside the container (21) and extending from the hub element (70) to the housing (42); an alternative drive assembly (40) substantially mounted inside the housing (42), the alternative drive assembly (40) being able to be operatively connected to the drive shaft (80) to impart alternative longitudinal movement to the mixing head (30 ); a linear bearing assembly (90) mounted on the table frame (50) in close relation to the housing (42) with the drive shaft (80) that can be operatively slid into said linear bearing assembly (90 ); where the mixing apparatus (20) can be placed on top of the container (21) with the drive shaft (80), the hub axis (B) and the center of symmetry all substantially aligned with said longitudinal axis (A), characterized because the housing (42) has a housing base plate (118) adjacent to its lower end, the table frame (50) has an upper plate (55) adjacent to its upper end, and in which the housing (42) It can be mounted on top of the top plate (55) in a removable mutual contact relationship.
