Description

Bioreactor (mixing) shaft rapid disassembly structure

Technical Field

The utility model discloses bioreactor instrument equipment field specifically is a bioreactor (mixing) shaft rapid disassembly structure.

Background

When animal cells are cultured in vitro, the bioreactor is a key device in the whole culture process, and provides a proper growth environment for the cells, so that the cells can rapidly proliferate and form a required biological tissue product. A laboratory type bioreactor for culturing animal cells is designed and produced according to the requirements of modern medicine and health and is used for culturing animal cells in the biological product industry. The method fully embodies the characteristics of modern large-scale animal cell culture, the tank body processing and the pipeline layout meet the sanitary pharmaceutical requirements, the parameter detection and control are accurate, and the control system is reasonable and simple in operation and convenient to operate.

The bioreactor needs the stirring shaft to continuously stir the culture medium to uniformly mix the cells and the nutrient substances in the cell culture process, the stirring shaft is driven by the motor, but the motor needs to be detached to clean the bioreactor after the cell culture is finished, and the motor can not bear the sterilization temperature, so that the motor also needs to be detached when the bioreactor is sterilized. Therefore, in the using process of the bioreactor, the motor and the stirring shaft need to be frequently disassembled and assembled, and although the standard coupler in the market can reliably connect the motor and the stirring shaft, the disassembly and the assembly of the coupler need tools and consume a certain time, and the operation is complicated, so the standard coupler in the market is not suitable for the bioreactor.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a bioreactor (mixing) shaft rapid disassembly structure to solve the problem that proposes among the above-mentioned background art.

In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a bioreactor (mixing) shaft rapid disassembly structure, is including the driving-disc of connection at agitator motor output, the equal spiro union in both sides on the driving-disc has the actuating lever, the top of actuating lever is provided with spacing portion, the bottom of actuating lever extends to the below of driving-disc, has placed the (mixing) shaft between two the actuating lever, the top of (mixing) shaft has radially run through there is the pinhole, the pinhole internal fixation pegs graft there is the round pin axle, the both ends dislocation ground of round pin axle is placed two between the bottom of actuating lever.

Optionally, the bottom end of the driving rod is conical.

Optionally, the bottom of the stirring shaft is axially fixed on the inner wall of the bioreactor.

Compared with the prior art, the utility model provides a bioreactor (mixing) shaft rapid disassembly structure possesses following beneficial effect: the utility model discloses well two actuating levers drive the round pin axle and rotate and then drive the (mixing) shaft and rotate, and the actuating lever does not have direct contact with the (mixing) shaft, consequently when agitator motor stopped, can directly take off agitator motor, and the light separation of realizing agitator motor and (mixing) shaft reaches the fast-assembling or the quick detach effect of (mixing) shaft.

Drawings

FIG. 1 is a schematic view of the quick-release structure of the stirring shaft of the bioreactor of the present invention.

In the figure: 1. a stirring motor; 2. a drive disc; 3. a drive rod; 31. a limiting part; 4. a stirring shaft; 41. a pin hole; 5. and (7) a pin shaft.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Example (b): please refer to fig. 1, the present application provides a bioreactor stirring shaft quick-release structure, which includes a driving disk 2 connected to the output end of a stirring motor 1, driving rods 3 are screwed on both sides of the driving disk 2, a limiting portion 31 is disposed at the top end of the driving rod 3, the bottom of the driving rod 3 extends to the lower side of the driving disk 2, a stirring shaft 4 is disposed between the two driving rods 3, a pin hole 41 is radially penetrated through the top end of the stirring shaft 4, a pin shaft 5 is fixedly inserted in the pin hole 41, and two ends of the pin shaft 5 are disposed between the bottoms of the two driving rods 3 in a staggered manner. Because the actuating lever 3 does not have direct contact with (mixing) shaft 4, so when agitator motor 1 stopped, can directly take off agitator motor 1, easily realize agitator motor 1 and (mixing) shaft 4's separation, reach the fast-assembling or the quick detach effect of (mixing) shaft 4.

Wherein, the bottom of actuating lever 3 is conical surface form, therefore agitator motor 1 when the installation, adjusts its bottom of actuating lever 3 position wantonly and can not contradict and extrude round pin axle 5.

In addition, the bottom of the stirring shaft 4 is fixed on the inner wall of the bioreactor through the axial nesting of the bearing, so as to ensure that the stirring shaft 4 does not move radially and reduce the vibration amplitude of the stirring shaft 4 in the stirring process.

It should be noted that, in this document, the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising an … …" does not exclude the presence of other identical elements in a process, method, article, or apparatus that comprises the element.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
