Description

Technical Field

[0001] The utility model relates to the field of bioreactors, in particular to a mixing container. Background Art

[0002] In the field of bioreactors, in order to provide cells with a better growth environment, it is necessary to mix the solution and increase the gas-liquid mass transfer rate. In the prior art, a stirring device is usually used to achieve this goal. However, the existing stirring devices are difficult to install, and the axis is unstable due to device wear, which increases the cost of use. At the same time, the stirring devices adapted for large-volume and large-capacity reactors have problems such as too long axial dimensions, easy breakage, and difficulty in transportation.

[0003] In the prior art, a foldable stirring shaft disclosed in a Chinese patent with publication number CN217527071U includes at least two rod bodies, a connecting piece is connected between two adjacent rod bodies, and the two adjacent rod bodies are hinged at the first end and the second end of the connecting piece respectively; a first reinforcing rib group is arranged on the rod body, the first reinforcing rib group includes a first reinforcing rib part and a second reinforcing rib part, the first reinforcing rib part includes a plurality of first reinforcing ribs, the plurality of first reinforcing ribs are arranged at intervals and are arranged on the surface of the rod body along the circumference of the rod body, the length of the first reinforcing rib extends along the axial direction of the rod body, the second reinforcing rib part includes a plurality of second reinforcing ribs, the plurality of second reinforcing ribs are arranged at intervals and are distributed on the surface of the rod body along the axis, and the length of the second reinforcing rib extends along the circumference of the rod body.

[0004] The agitator shaft disclosed in the above patent adopts a folding method to reduce the axial size of the agitator shaft to facilitate transportation. However, the foldable agitator shaft does not reduce the volume occupied by the agitator shaft while reducing the axial size, and the beneficial effect on transportation is not significant. In addition, when installing the foldable agitator shaft, the agitator shaft needs to be unfolded, adjusted in position, and then installed, which makes the installation process more cumbersome.

[0005] In order to solve the problems existing in the prior art, the utility model provides a mixing container.

[0006] A mixing container comprises a container wall and a stirring device at least partially placed in the container wall, the stirring device comprises a connecting device, a stirring shaft, and a magnetic connecting device fixed to the container wall, the stirring shaft comprises a first connecting end and a second connecting end, the connecting device is detachably fixed to the first connecting end, the connecting device is fixed to the container wall, the magnetic connecting device is magnetically connected to the second connecting end, and the magnetic connecting device and the second connecting end are arranged separately.

[0013] Preferably, the stirring shaft is further provided with a stopper, and the stopper is used to prevent the first part and the second part from separating from each other.

[0014] Specifically, this structure makes the relative position between the first part and the second part more stable, prevents the first part from falling off the second part, and also limits the maximum axial dimension of the stirring shaft; at the same time, since only one of the first part and the second part will be connected to the driving mechanism, the stopper also has the function of transmitting power.

[0023] Preferably, a driving device is also included, and the connecting device is a first bearing, the first connecting end is connected to the driving device through the first bearing, the driving device is arranged on the outside of the container wall, and a through hole is provided on the container wall for connecting the driving device to the stirring shaft.

[0024] Specifically, the structure in which the driving device is arranged outside the container wall makes it easier to install the mixing container on the bioreactor, and can significantly increase the service life of the driving device.

[0025] Preferably, it further comprises a fixing device, wherein the fixing device is arranged opposite to the driving device, and the magnetic connecting device is connected to the fixing device via a second bearing.

[0028] Specifically, under this structure, a relatively sealed internal structure is still formed between the container wall, the first bearing and the second bearing, and the liquid to be mixed is placed in the internal structure.

[0029] Compared with the prior art, the utility model is beneficial in that:

[0030] (1) The structure in which one end of the stirring shaft is detachably connected to the driving device and the other end is magnetically connected to the magnetic connecting device significantly reduces the difficulty of installing the stirring shaft and does not negatively affect the stability of the axis of the stirring shaft when it rotates.

[0031] (2) The second connection end is magnetically connected to the magnetic connection device, but they are separated from each other. Therefore, during the rotation and stirring of the stirring shaft, there will be no friction between the magnetic connection device, the second connection end and other components due to rotation, that is, no wear will occur between the related components, thereby significantly extending the service life of the related components.

[0032] (3) The axial dimension of the stirring shaft is variable, so that a stirring shaft with a larger size can also be easily transported. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] One end of the stirring shaft 30 is detachably connected to the connecting device 51, and the other end is detachably connected to the magnetic connecting device 40. Therefore, during the specific installation process, the stirring shaft 30 only needs to be connected to the connecting device 51, and the second connecting end can be installed without additional installation steps under the magnetic force of the magnetic connecting device 40, which greatly simplifies the installation process.

[0052] A plurality of stirring paddles 36 are disposed on the stirring shaft 30 .

[0053] The structure of providing the stirring paddle 36 on the stirring shaft 30 can realize more uniform stirring of the liquid in the container wall 10, which is more conducive to the mixing of the liquid.
