A mixing device includes a base, shaft, impeller sleeve, and impeller blades. The base can be constructed for releasable attachment to an opening of a container, such as a 55-gallon drum. The shaft extends from the base and is coupled thereto such that rotation can be transmitted to the shaft by way of or through the base. The impeller sleeve is mounted on the shaft and supports the impeller blades. Each impeller blade includes an attachment leg and a stirring leg extending from the attachment leg. The impeller blades are supported so as to transition from a collapsed position with the stirring leg proximal to a central axis of the shaft to an extended position with the stirring leg distal from the central axis when the shaft is rotated. Each impeller blade can be formed of a plastic, such as a glass-filled polypropylene or glass-filled nylon.

Mixing systems, methods, and devices with extendible impellers

A mixing assembly includes a drum including a side wall, a top portion, and a bottom portion, in which the top portion includes a first opening for filling a substance into the drum, a second opening for mixing the substance in the drum, and a third opening for extracting the substance from the drum; and a mixer releasably disposed in the drum, including a head releasably attached to the second opening for mixing, in which the head includes a housing including an internal hollow region extending along the central axis of the head, and external threads configured to be attached to the second opening for mixing by thread engagement, a shaft disposed in the hollow region, and an impeller assembly disposed at a bottom end of the shaft for stirring the substance in the drum.
