A blade is disclosed for use in a mixing impeller assembly. The blade includes a top skin element and a bottom skin element without an internal framework in between the elements. A unitary pre-shaped tip element is attached at an end of the blade to the top and bottom skin elements. The tip is welded to the top skin and the bottom skin, and has a bevel at the weld location. The top skin has an edge that abuts the tip and the lower skin has an edge that abuts the tip, and respective bevels are provided on these edges.
摘要:
An impeller blade for a top skin element joined to a bottom skin element. The blade can have an air foil shape. A pre-shaped tip is joined to the radial outside end of the blade.

A weir assembly for use with a mixer-settler for liquid-liquid extraction includes in one embodiment an organic weir having an inlet opening below the free surface of the organic phase liquid and a vertically-adjustable front wall allowing adjustments in the position and/or height of the inlet opening. The organic weir can also feature an angled bottom coupled to a lip segment, an incline plate in the interior of the weir, and a front wall that is angled with respect to incoming fluid flow. In another embodiment the weir assembly can independently or additionally include an aqueous weir with a labyrinth section. The aqueous weir can optionally include an adjustable lip hingedly coupled to the top of the final partition in the labyrinth section.

An impeller assembly, comprising a generally planar disc oriented in a first plane and having a circular outer edge; and a plurality of blades mounted to the disc and extending beyond the edge of the disc, with the blades in cross-section having a shape that is substantially symmetrical along a center line and having a first segment and a second segment disposed on opposite sides of the center line, with one segment being symmetrical with at least a portion of the other segment, and with the blades mounted so that the respective center line of each blade is at an angle relative to the first plane in which the disc lies. In another variation, the blades are mounted so the center line of each blade is offset from the plane in which the disc lies.

An impeller for use with a mixing vessel having a diameter, wherein the impeller is mountable onto a rotatable shaft that includes a flange. The impeller includes a single blade pair member. The blade pair member has a central hub portion and a first and second blade connected to the central hub portion. The first and second blades each include a generally planar portion, a tip portion and a trailing edge, wherein the generally planar portion and the tip portion intersect at a line of intersection, which is an angle relative to the trailing edge.
