Description

Technical Field

[0001] This application relates to the field of biopharmaceuticals, and particularly to a rocking reactor. Background Art

[0002] In the field of biopharmaceuticals, during processes such as cell culture, formulation and mixing, in order to enhance the mixing effect, mass transfer and dissolved oxygen, etc., it is usually achieved by operating such as mixing and temperature control of the reaction system.

One end of the second fixed frame 6 is connected to the second linkage rod 7, and the other end is connected to the second driven unit 5. The second linkage rod 7 is connected to the second power source 8.

[0057] The second power source can be a reduction motor. The second driven unit can be a vertical rod, and the vertical rod can be a cylindrical, prismatic, frustum or truncated pyramid structure.

[0058] The second fixed frame can be an inverted "U" shape. For example, the second fixed frame is composed of a second cross bar, a first vertical rod B and a second vertical rod B. The first vertical rod B and the second vertical rod B are respectively arranged at both ends of the second cross bar. The first vertical rod B and the second vertical rod B are in the same direction and are both perpendicular to the second cross bar. The middle part of the side of the second cross bar away from the first vertical rod B and the second vertical rod B is connected to the second driven unit, and the second driven unit is perpendicularly arranged to the second cross bar. The second linkage rod includes a first linkage piece B and a second linkage piece B.

One end of the first linkage piece B away from the reduction motor is connected to the first vertical rod B, and one end of the second linkage piece B away from the reduction motor is connected to the second vertical rod B.

[0059] The third driving component includes a third power source 12 and a third linkage. The third power source 12 is connected to the third linkage, and the third power source 12 is used to drive the third linkage to perform a rotational motion.

[0060] The third linkage includes a third linkage unit and a third driven unit 9. The third driven unit 9 is located at the top of the third linkage unit. The third linkage unit is connected to the third power source 12, and the third driven unit 9 is connected to the swing box body 14.

One end of the first linkage piece C away from the reduction motor is connected to the first vertical bar C, and one end of the second linkage piece C away from the reduction motor is connected to the second vertical bar C.

[0063] Furthermore, two or three of the first linkage member, the second linkage member, and the third linkage member do not rotate synchronously. In this application, synchronous rotation means rotating at the same time and at the same rotational speed.

[0064] Since two or three of the first linkage member, the second linkage member, and the third linkage member do not rotate synchronously, the swinging box body is driven to swing in multiple dimensions.

[0065] Specifically, when the first driving assembly operates, the reduction motor drives the first linkage piece and the second linkage piece to rotate synchronously. The first linkage piece and the second linkage piece drive the first fixed frame 2 to perform a rotational motion (the rotation trajectory is an ellipse), thereby driving the first driven unit 1 and the swinging box body 14 to move. The same applies to the second driving assembly and the third driving assembly. Since the starting times of the first driving assembly, the second driving assembly, and the third driving assembly are different, and the rotational speed of the reduction motor is different, the swinging box body 14 performs a multi-dimensional swinging motion.

[0066] In the present application, when the reactor is operating, the first power source 4 first drives the first linkage rod 3 to rotate. The first linkage rod 3 drives the first fixed frame 2 and the first driven unit 1 to rotate in the first direction. Then, after a given time (the given time can be 1 - 10 s, preferably 1 - 3 s), the second power source 8 drives the second linkage rod 7 to start rotating. The second linkage rod 7 drives the second fixed frame 6 and the second driven unit 5 to rotate in the second direction. Then, after another given time (the given time is 1 - 10 s, preferably 1 - 3 s), the third power source 12 drives the third linkage rod 11 to start rotating. The third linkage rod 11 drives the third fixed frame 10 and the third driven unit 9 to rotate in the third direction. Through the rotation of the first linkage member, the second linkage member, and the third linkage member in three directions, the swing box body 14 performs multi-dimensional swinging motion.

[0067] In the present application, the swing box body 14 includes a box body and a box cover, and the box body is fixedly connected to the box cover.

[0068] In the present application, the bottom of the box body is connected to the first linkage member, the second linkage member, and the third linkage member.

[0069] A heating blanket and a temperature sensor are further provided in the box body. The temperature sensor is in contact with the heating blanket. The heating blanket is used to heat the liquid sample in the box body. The temperature sensor is used to record the temperature of the liquid sample.

[0070] A flip cover that can be flipped is provided on the box cover.

[0071] In the present application, the reactor further includes a control mechanism 17, and the control mechanism 17 is used to control the swing box body 14, the swing mechanism 15, and the weighing mechanism 16.

[0072] The control mechanism 17 is located below the weighing mechanism 16. A display screen is provided on the control mechanism 17. The display screen is electrically connected to the temperature sensor, the heating blanket, the weighing mechanism 16, the first driving component, the second driving component, and the third driving component. The operating states of the temperature sensor, the heating blanket, the weighing mechanism 16, the first driving component, the second driving component, and the third driving component are controlled and displayed through the display screen.

[0074] Unless otherwise specified, the experimental methods used in the following embodiments are all conventional methods.

[0075] Unless otherwise specified, the materials, reagents, etc. used in the following embodiments can all be obtained from commercial channels.

[0076] Example 1

[0077] The rocking reactor in this example is as follows Figure 1 and Figure 2 shown. The reactor includes a rocking box body 14, a rocking mechanism 15, a weighing mechanism 16, and a control mechanism 17 that are sequentially arranged from top to bottom.

[0078] The rocking box body 14 includes a box body and a box cover. The box body is fixedly connected to the box cover. The bottom of the box body is connected to the rocking mechanism 15. A heating blanket and a temperature sensor are placed on the bottom inside the box body. The heating blanket is located at the center of the bottom of the box body, and the middle of the heating blanket has a circular opening. The temperature sensor is in contact with the heating blanket. The heating blanket is used to heat the liquid sample inside the box body. The temperature sensor is used to record the temperature of the liquid sample. A flip cover that can be flipped is provided on the box cover.

[0079] The swing mechanism 15 includes a housing (the housing can be cube-shaped). At the bottom inside the housing, there is a swing bottom plate 13. On the swing bottom plate 13, three groups of driving components are arranged. The three groups of driving components are 120° to each other, and they are the first driving component, the second driving component, and the third driving component respectively. The structures of the three groups of driving components are the same. Taking the first driving component as an example, the first driving component includes a first power source 4 and a first linkage. The first power source 4 is connected to the first linkage, and the first power source 4 is used to drive the first linkage to perform a rotational motion. The first power source 4 is a reduction motor. The first linkage includes a first driven unit 1 (the first driven unit 1 is a vertical rod), a first linkage rod 3, and a first fixed frame 2. The first driven unit 1 is arranged at the top of the first fixed frame 2. One end of the first driven unit 1 away from the first fixed frame 2 is connected to the bottom of the swing box body 14. The first fixed frame 2 is composed of a first cross bar, a first vertical rod A, and a second vertical rod A. The first vertical rod A and the second vertical rod A are respectively arranged at both ends of the first cross bar. The first vertical rod A and the second vertical rod A are in the same direction and are both perpendicular to the first cross bar. The middle part of the side of the first cross bar away from the first vertical rod A and the second vertical rod A is connected to the first driven unit 1, and the first driven unit 1 is perpendicularly arranged with the first cross bar. The first linkage rod 3 includes a first linkage piece A and a second linkage piece A. The first linkage piece A and the second linkage piece A are respectively connected to the rotating shaft of the reduction motor. One end of the first linkage piece A away from the reduction motor is connected to the first vertical rod A, and one end of the second linkage piece A away from the reduction motor is connected to the second vertical rod A. When the first driving component operates, the reduction motor drives the first linkage piece A and the second linkage piece A to rotate synchronously. The first linkage piece A and the second linkage piece A drive the first fixed frame 2 to perform a rotational motion (the rotation trajectory is an ellipse), thereby driving the first driven unit 1 and the swing box body 14 to move. Since the starting times of the first driving component, the second driving component, and the third driving component are different, and the rotational speeds of the reduction motors are different, the swing box body 14 performs a multi-dimensional swing motion. In this embodiment, the rotational speeds of the first driving component, the second driving component, and the third driving component are 50 revolutions / min, 55 revolutions / min, and 60 revolutions / min respectively. The second driving component starts to operate 1 s - 3 s after the first driving component starts to operate, and the third driving component starts to operate after another 1 - 3 s.

[0080] The control mechanism 17 is used to control the swing box body 14, the swing mechanism 15, and the weighing mechanism 16.

[0081] The control mechanism 17 includes a housing (the housing can be a cubic structure). Electronic components are arranged inside the housing. The electronic components are electrically connected to the temperature sensor, the heating blanket, the weighing mechanism 16, the first drive assembly, the second drive assembly, and the third drive assembly. A display screen is arranged on the surface of the housing. The display screen controls and displays the operating states of the temperature sensor, the heating blanket, the weighing mechanism 16, the first drive assembly, the second drive assembly, and the third drive assembly through the electronic components.
