Abstract
A chemical mixer tool for use in a storage drum is described. The chemical mixer tool typically comprises a mixer housing assembly in which one end of a mixer shaft is secured, the distal end of the mixer shaft having at least one collapsible impeller assembly removably attached thereon. The chemical mixer tool is configured to be removably secured to the top portion of the storage drum, with the distal end of the mixing shaft extending into the interior of the storage drum.

A chemical mixer tool for use in mixing the liquid contents in a storage drum comprising:
- a mixer housing assembly, said mixer housing assembly configured to removably attach to a top portion of the storage drum;
- a mixer shaft having a longitudinal axis, said mixer shaft rotatably coupled to said mixer housing assembly near the proximal end of said mixer shaft;
- and
- a first impeller assembly including:
- a first impeller collar, said first impeller collar removably attached proximate the distal end of said mixer shaft, the first impeller collar further including one or more first blade stops;
- and
- one or more first pitch blades each having an inner blade surface and said first pitch blades rotatably contained by said first impeller collar, each of the one or more first pitch blades resting against and in contact with a respective first blade stop of the one or more blade stops when in a resting position, each inner blade surface (i) being canted outwardly no less than 5 degrees off parallel of the longitudinal axis of said mixer shaft when the associated first pitch blade of the one or more pitch blades is in the resting position, and (ii) is configured to rotate outwardly from the longitudinal axis of said mixer shaft as said mixer shaft is rotatably engaged.
