Description

Technical Field

[0001] The utility model belongs to the technical field of biological treatment, in particular to a propeller used for biological treatment. Background Art

[0002] One of the most common drug states in biomedical activities is fluid. In the process of preparing fluid drugs, one of the most common equipment is the propeller. The propeller is used to push the biomedical material into a bioreactor bag or reactor. The existing bioprocessing propeller used in biomedicine mainly includes a circular shell, a drive motor and fan blades. The drive motor provides rotational power to the fan blades, thereby achieving the effect of directional guidance of the biomedical material.

[0003] A Chinese patent application (or patent) with publication number CN106040055B discloses a propeller for a biological container, comprising: (a) a hub, the hub comprising a top end and a bottom end, and at least a first propeller slot and a second propeller slot, the first propeller slot and the second propeller slot being arranged vertically and extending from the top end to the bottom end; (b) at least a first propeller blade and a second propeller blade extending from the hub, each propeller blade comprising a blade surface, an arm having a first end and a second end and a recess between the first end and the second end, wherein the first end is adjacent to the blade surface, the second end extends into the propeller slot, the arm is engaged in the propeller slot, and wherein the second end of the arm of the first propeller blade is engaged with the recess of the arm of the other propeller blade.

[0004] The above-mentioned propeller for biological container includes a hub installed on the first end of the rotatable shaft. At the same time, the rotatable shaft includes a cylindrical element, the cylindrical element has a first end and a second end, and the shaft has a vertical rotation axis, wherein the hub is installed on the first end of the rotatable shaft, which means that the axial propeller blades provide the rotational force, and the power of the shaft comes from the drive motor. Therefore, the propeller not only has blades but also a rotatable shaft and a drive motor, and the various components need to be meshed through gears and shaft linkage, and the gears and shaft systems are both inside the propeller. Therefore, when working, not only Noise will be generated. At the same time, when the fluid passes through the shuttle propeller, it will contact and collide with the housing where the gears and shaft system are located, causing certain turbulence problems; and the outer sides of the multiple shaft systems and gears arranged thereon need to be provided with a protective shell, and the protective shell is connected to the housing of the hub on the propeller, and they are also in a connected state with each other. In particular, the rotatable shaft driving the propeller blades and its housing must ensure both sealing and rotatability, so there will still be a certain gap between them. This gap will cause the sealing between the shaft and the hub housing to be weak, and the solution will flow into the interior of the hub housing through the gap. To this end, we provide a propeller for bioprocessing to solve the above-mentioned problems. Utility Model Content
