Technical Field

[0001] This utility model relates to the field of microalgae cultivation technology, and in particular to a microalgae cultivation bag with a mixing function. Background Technology

[0002] As a high-value biological resource, the uniform mixing of the culture medium is crucial for algal cell growth efficiency and product synthesis during the large-scale cultivation of microalgae. Traditional cultivation bags mostly use static culture or external stirring equipment, which has the following technical defects: poor mixing effect: static culture is prone to uneven distribution of nutrients, dissolved oxygen and light, and algal cells settle to form "dead zones"; complex structure: external stirring equipment requires matching motors, bearings and other mechanical parts, increasing equipment cost and maintenance difficulty; high risk of contamination: rigid stirring paddles are prone to wear and tear when in contact with the cultivation bag, which can damage microalgae and is difficult to clean, potentially leading to microbial contamination.

[0003] For example, in the prior art, Chinese patent application number CN213913465U discloses an immune cell culture bag mixing device, which achieves bidirectional rotation through the linkage of a rotating table and an incubator. However, this device relies on external mechanical drive, has a complex structure, and is not suitable for flexible culture bags. The cage-type stirring device proposed by Chinese patent application number CN207811737U requires an aeration system, which increases energy consumption and equipment complexity. Therefore, a microalgae culture bag with mixing function is proposed. Utility Model Content

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Example 1:

[0019] Reference Figure 1-6 A microalgae cultivation bag with a mixing function includes a cultivation bag body 1, a bag cavity 101 for microalgae cultivation inside the cultivation bag body 1, an aeration device at the bottom of the cultivation bag body 1, the aeration device including an aeration pipe 2 disposed in the bag cavity 101 and an air supply pipe 102 disposed on the cultivation bag body 1; the aeration pipe 2 and the air supply pipe 102 are connected through a connecting pipe 201; and an aeration disc 202 is connected to the aeration pipe 2. When carbon dioxide gas is added to the bag cavity 101, an air pump is connected to the air supply pipe 102. The gas is discharged from the aeration disc 202 through the aeration pipe 201 and the aeration pipe 2, so that the gas generates bubbles in the microalgae solution in the bag cavity 101. It also includes a suspended ball 5 disposed inside the bag cavity 101, the lower end of which is fixed to the aeration device by an elastic rope 4; Among them, the suspended ball 5 is located at the upper end of the aeration disc 202. When the aeration device supplies air into the bag cavity 101, the rising bubbles in the microalgae solution will push the suspended ball 5, causing the suspended ball 5 to sway in the horizontal direction within the bag cavity 101. The suspended ball 5 will squeeze the flow and fusion of the microalgae solution within the bag cavity 101. Furthermore, when the bubble thrust is large enough to lift the suspended ball 5, under the action of the elastic rope 4, the range of motion of the suspended ball 5 is larger, and the mixing effect is better. By using suspended balls 5 and aeration, the microalgae solution can flow in both vertical and horizontal directions, improving the mixing effect of the microalgae culture medium.

[0020] A fixing ring 3 is installed on the aeration pipe 2, and an elastic rope 4 is sleeved in the arc groove on the fixing ring 3. A limit buckle 301 for preventing the elastic rope 4 from leaving the arc groove is detachably connected to the fixing ring 3.

[0021] The limit buckle 301 is a magnetic buckle. The limit buckle 301 is magnetically attracted to the fixing ring 3. After the limit buckle 301 is removed by magnetic action, the elastic rope 4 can be removed from the fixing ring 3, which makes it easy to disassemble and replace the elastic rope 4 of different lengths.

[0022] The suspended ball 5 is an elastic ball. When gas is added to the suspended ball 5, the size of the suspended ball 5 can be adjusted, which has a wide range of applications. A connector 501 is fixedly connected to the suspended ball 5. The connector 501 is connected to the elastic rope 4. The connector 501 is equipped with an inflation / deflation pipe 502. Example

[0023] Reference Figures 1-6 and Figure 8 A microalgae cultivation bag with a mixing function, wherein at least three sets of suspended balls 5 are provided, which can squeeze and mix the algae solution at different positions; two adjacent suspended balls 5 are staggered in the height direction of the bag cavity 101, which can mix the microalgae solution at different heights. Example 2:

[0024] Reference Figures 1-6 and Figure 7 A microalgae cultivation bag with a mixing function, wherein at least three sets of suspended balls 5 are provided.

[0025] Two adjacent suspended spheres 5 are located on the same plane within the height of the pocket cavity 101.

[0026] A magnetic ring 503 is fixedly connected to the connector 501, and the magnetic rings 503 inside two adjacent suspended balls 5 repel each other magnetically. When one of the suspended balls 5 is driven, the adjacent suspended balls 5 can move synchronously under the action of magnetic force, which has a better mixing effect on the microalgae solution. Furthermore, the magnetic force prevents the suspended spheres 5 from expanding or tangling.

[0027] This invention, through its aeration device and suspended ball 5 pulled by elastic rope 4, can mix microalgae solution evenly. It has a simple structure, does not easily damage microalgae cells, and has a good mixing effect.

[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
