Mixing devices and associated methods are described herein. A mixing device configured in accordance with embodiments of the present technology can include, for example, a plate configured to rotate about a longitudinal axis and a plurality of enclosures coupled to the plate. The enclosures can each include (a) at least one sidewall that defines an oblique angle with the plate and (b) a chamber configured to receive a media and a fluid. The enclosures can be fluidly coupled to a fluid source for receiving the fluid in the chambers. When the plate is rotated, the enclosures revolve about the longitudinal axis to mix the media with the fluid in the chambers.

A fluid mixing system includes a flexible bag having a first end, an opposing second end, and an interior surface bounding a compartment. A first rotational assembly includes a first casing mounted to the first end of the flexible bag and a first hub rotatably mounted to the first casing. A second rotational assembly includes a second casing mounted to the second end of the flexible bag and a second hub rotatably mounted to the second casing. An elongated member has a first end coupled with the first hub and an opposing second end coupled with the second hub, the connector being flexible and having a uniform flexibility along its entire length. A first impeller is mounted to the connector.

A fluid mixing system includes a flexible bag having a first end, an opposing second end, and an interior surface bounding a compartment; a retainer coupled to the second end of the flexible bag, the retainer having a retention cavity formed thereon that communicates with the compartment of the flexible bag; and an elongated member having a first end rotatably coupled to the first end of the flexible bag and an opposing second end freely disposed within the retention cavity of the retainer so that the second end of the elongated member can rotate within the retention cavity relative to the retainer.

A receptacle has a wall defining a receptacle interior and a shaft housing for guiding a shaft through the wall into the receptacle interior. The shaft housing defines an annular cap with spaced apart inner and outer walls connected by an inner end face facing the receptacle interior. A shaft guide part has an end facing the receptacle interior and an outer surface that defines a gap relative to the inner wall of the shaft housing. The shaft guide part has an annular wall spaced apart from and parallel to its outer surface. The annular wall extends over the free end of the inner wall of the shaft housing and is sealed to the inner and outer walls of the shaft housing by at least one seal each. The shaft guide part is mounted in the shaft housing by a radial ball bearing and by an axial ball bearing.

A fluid mixing system includes a flexible bag having a first end, an opposing second end, and an interior surface bounding a compartment. A first rotational assembly includes a first casing mounted to the first end of the flexible bag and a first hub rotatably mounted to the first casing. A second rotational assembly includes a second casing mounted to the second end of the flexible bag and a second hub rotatably mounted to the second casing. A connector has a first end coupled with the first hub and an opposing second end coupled with the second hub, the connector being flexible and having a uniform flexibility along its entire length. A first impeller is mounted to the connector.

The present disclosure relates to a mixing assembly for a fluid mixing system. The mixing assembly includes a first rotational assembly having a first casing and a first hub rotatably mounted to the first casing, a second rotational assembly having a second casing and a second hub rotatably mounted to the second casing, an elongated member having a first end coupled with the first hub and an opposing second end coupled with the second hub, and one or more impellers secured to the elongated member.

A mixer is provided for mixing a substance in a container. The mixer includes a motor; a frame configured to be controlled by the motor to rotate on an axis; a carrier disposed at a first end of the frame and configured to hold the container; a counterweight disposed at a second end of the frame opposite to the carrier, wherein the counterweight position relative to the axis is adjustable. The mixer may be a stand-alone unit, or it may be disposed in an apparatus for dispensing a cosmetic composition.

The present invention provides a vertically movable blender comprising: a housing for forming the exterior thereof; a first motor which includes a first shaft having a hollow portion, and which is disposed inside the housing; a second shaft which is disposed to pass through the hollow portion of the first shaft so as to be slidable, and which rotates simultaneously with the first shaft; an actuator disposed inside the housing so as to provide driving force for sliding of the second shaft; and a clutch disposed at one end of the second shaft so as to rotate simultaneously therewith.

A fluid mixing system includes a flexible bag having an interior surface bounding a compartment. A retainer is coupled to the flexible bag, the retainer having a retention cavity formed thereon that communicates with the compartment of the flexible bag. An elongated tubular connector has a first end coupled to the flexible bag and an opposing second end projecting into the compartment thereof. An impeller is disposed within flexible bag and is coupled with the tubular connector. A steady support is mounted on the second end of the tubular connector and terminates at a distal nose, the distal nose being freely disposed within the retention cavity of the retainer so that the steady support can rotate within the retention cavity relative to the retainer.

A conical impeller with a hub that has a conical surface extending into the interior of the impeller. The hub has spiral, slanting arms which are attached or integrally formed with a plurality of curved blades. The blades can be connected at the bottom by a ring. The intersection of the conical surface of the hub with the blade forms an upward path for fluids and their entrained particles or gases which have been brought into the interior of the impeller to effectively completely be ejected. The discharge edges of the blades and/or the conical surface of the hub may have openings for discharging gas into the fluid. The impeller imparts low shear to the fluid and its components, and the shear is independent or only depends slightly on the size of the impeller. The impeller minimizes or eliminates particle agglomeration and fouling of the impeller. The efficiency of and flow pattern produced by the impeller means that containers don't require the use of baffles. The high efficiency and low shear of the impeller is useful for applications such as mixing of biological fluids, decontamination of produced water, chemical mechanical polishing, and flotation cells. The impeller may be raised or lowered in the mixing vessel, and may incorporate embedded sensors.
