A method of mixing a fluid includes at least partially unfolding a collapsible bag bounding a compartment, the collapsible bag containing in the compartment at least a portion of an elongated drive line or drive shaft and an impeller secured to the drive line or drive shaft, the impeller including a plurality of impeller blades that are pivotable relative to the drive line or drive shaft, at least one of the plurality of impeller blades being in a collapsed position. A fluid is delivered into the compartment of the collapsible bag. The drive line or drive shaft is then rotated so as to rotate the impeller within the compartment and mix the fluid therein, the at least one of the plurality of impeller blades pivoting from the collapsed position to an expanded position as the impeller is rotated within the compartment.

The present disclosure relates to a tool set for disassembly and assembly of a crusher blade. The tool set of the present disclosure may provide a dedicated hand tool that facilitates quicker and safer disassembly and assembly of the blade when separating or replacing the crusher blade. That is, during the disassembly and assembly of the blade inside the crusher container, the blade can be disassembled and assembled by rotating the fastening member for fixing the blade in the opposite direction of the fastening direction without having to hold the sharp blade directly by hand, thereby ensuring that the blade replacement or removal can be performed safely and quickly.

A fluid mixing system includes a support housing having an interior surface bounding a chamber. A flexible bag is disposed within the chamber of the support housing, the flexible bag having an interior surface bounding a compartment. An impeller is disposed within the chamber of the flexible bag. A drive shaft is coupled with the impeller such that rotation of the drive shaft facilitates rotation of the impeller. A drive motor assembly is coupled with the draft shaft and is adapted to rotate the drive shaft. An adjustable arm assembly is coupled with the drive motor assembly and is adapted to move the drive motor assembly which in turn moves the position of the drive shaft and impeller. An electrical controller can control movement of the adjustable arm.

A method for connecting functional elements (14) to a shaft (10, having the following steps: (a) forming elevations (12) for receiving the functional elements (14), said elevations (12) being machined out of the shaft (10) by removing material, and (b) welding the functional elements (14) to the elevations (12) on the shaft (10).

This application discloses a stirrer with a direct drive motor comprising a stator module with a rod mounted onto a stator and a rotor module comprising a rotor encapsulated in a housing and connected to an impeller. In some embodiments the rod functions as a cooling device to prevent the stator from being overheated during stirring. The stator module and the rotor are encapsulated in their separate housing and are detachable from each other and the impeller to allow the user to clean, disinfect, maintain or repair the stator module, rotor, impeller, and coupling between the stator module and the rotor before further use. Depending on the type of impeller added, it may be used for moving, stirring, mixing, agitating, blending, aerating, homogenizing, or cutting the medium.

Embodiments of the present disclosure relate to a food waste disposer, and more specifically, to a food waste disposer which prevents the formation of a blind spot where food accumulates through the shape of a chamber in which food and microorganisms are accommodated, and improves the efficiency of food decomposition and processing by effectively stirring the food and microorganisms using blades and stirring rods.

A waste treatment apparatus includes: a body having a spherical shape and configured to accommodate a waste therein; and a stirring unit configured to stir the waste accommodated in the body. The stirring unit includes: a main shaft horizontally and rotatably disposed at a center portion in the inside of the body; a plurality of main shaft stirring blades having a flat plate shape, the plurality of main shaft stirring blades mounted on a surface of the main shaft; a plurality of support rods assembled to the main shaft at a predetermined interval, the plurality of support rods extending perpendicularly toward an inner peripheral surface of the body; and a plurality of stirring blades each having a rectangular flat plate shape, the plurality of stirring blades being mounted on distal ends of the plurality of support rods on an inner peripheral surface side of the body.

A stirrer arrangement including a shaft, a drive device, a hub body, and at least two blades. The at least two blades are arranged on the hub body and extend radially from the hub body relative to the rotational axis. Each of the at least two blades has a foot that is configured to fasten on the hub body and, along a radial extent, a leading-edge region and a trailing-edge region opposite the leading-edge region. The hub body has a wall in which depressions are provided to receive the blade feet. On an outside of the wall, recesses are provided which reach up to a part portion of the depressions. In a vicinity of the foot, each blade has an extent which protrudes beyond the foot, is formed by the leading-edge region and protrudes into the respective recess.

The stirring device, in particular for a fluid-mixing bioreactor, comprises a drive shaft including a rod, an agitating element and a sleeve of tubular shape. The sleeve forms a coupling sleeve receiving the shaft therethrough and is directly rotationally coupled to the rod. The agitating element, which has a hub with an annular side wall delimiting an inner space and an impeller assembly comprising blades, is indirectly rotationally coupled to the rod via the sleeve that is engaged in the inner space. One of an inner surface of the wall and an outer surface of the sleeve is a guiding surface with progressively reduced cross section. Axial movement between the hub and the sleeve is prevented in a locked configuration of a sleeve fastening arrangement. Hub-sleeve contact areas can be axially distributed.

The present disclosure relates to the technical field of packaging, and discloses a hybrid cosmetics packaging device comprising a housing, and a mixing mechanism, a discharge mechanism, storage bottles and a PLC arranged within the housing, wherein the mixing mechanism comprises a mixing chamber, a stirring assembly and supplying assemblies, the supplying assembly conveys base materials in the storage bottles to the mixing chamber, and the discharge assembly conveys a cosmetic product in the mixing chamber to a product outlet. The housing is provided with a skin detector which measures a water-to-oil ratio of skin and feeds back same to the PLC, and the PLC outputs a signal to the supplying assemblies to adjust discharge amount of base materials discharged from the storage bottles. In the present disclosure, the proportion of each base material can be adjusted in a personalized mode according to the skin state of a user.
