Description

Technical Field

[0001] The utility model relates to an indoor microalgae cultivation device, belonging to the technical field of cultivation devices. Background Art

[0002] Microalgae are rich in nutrients such as carotene, phycobiliproteins, polyunsaturated fatty acids, polysaccharides, and sterols. They possess antibacterial, antioxidant, anti-inflammatory, anti-cancer, and cosmetic activities, and have been developed and utilized by humans since ancient times as high-value food and health products. Microalgae are diverse in genera and categories, and different species have different requirements for cultivation conditions such as light, temperature, pH, water quality, and growth sources. Currently, commercial microalgae cultivation is primarily based on outdoor cultivation to facilitate large-scale cultivation. However, since the cultivation conditions in large outdoor spaces are highly dependent on the local climate, the types of microalgae that can be cultivated are relatively limited.

[0003] For example, the application number: 202221987599.9 discloses a single-cell algae culture device, an algae culture vessel with a carbon dioxide delivery device, the main body of the culture vessel is a transparent bottle body, which is made of transparent plastic; the top of the culture vessel is provided with a bottle cap, and the bottle cap is provided with an air inlet and an air outlet; during the culture process, carbon dioxide gas is generated by a carbon dioxide generator, and the gas is transported to the interior of the bottle body through a gas pipeline to supplement the carbon dioxide required for algae growth and stir the culture liquid, thereby destroying the biofilm produced by the algae and promoting its growth.

[0004] For example, the algae cultivation device disclosed in the application number: 202223197090.7 proposes a cylindrical cultivation device equipped with a fluid replenisher, a lamp, a stirring element, an aeration element, a heating element, a temperature sensor, a chlorophyll sensor and a liquid level sensor; the box body of the cylindrical cultivation device is provided with a transparent inner wall and a reflective outer shell, a plurality of lamps are provided in the gap between the inner wall and the outer shell, a cover body that seals the box body is provided on the top of the box body, and a visual window, a flip-up algae inlet and a controller are provided on the cover body, and the controller controls the operation of the fluid replenisher, the lamp, the stirring element, the aeration element, the heating element and the sensor. The present invention accurately controls the growth conditions of the algae in the incubator through devices such as fluid replenishment, lighting, stirring, aeration, heating, and chlorophyll monitoring, thereby improving the cultivation efficiency; the sealed box body helps to isolate the influence of the external environment and pollutants.

[0005] For example, a combined algae cultivation device disclosed in application number: 202223296671.6 proposes a combined algae cultivation device, which is composed of a ventilation device, a liquid cooling device, a transparent cylindrical sealed box and a transparent sub-column arranged on the top of the box; during the cultivation process, the algae liquid circulates between the box and the sub-column through the stirring action of the gas transported by the ventilation device, thereby realizing the circulation of algae between different lighting areas and meeting its growth lighting requirements; at the same time, the control of the cultivation temperature is completed by the liquid cooling pipe on the outside of the box, and cold / hot water is passed through the pipe to adjust the temperature of the box.

[0006] Based on the above search and analysis, it is concluded that the existing technology still has deficiencies:

[0007] 1. The box is made of transparent plastic (mainly organic glass), which is expensive and has a small volume. The box is cylindrical and difficult to process. The internal structure of the box is relatively complex, which increases the manufacturing cost of the box.

[0008] 2. The box adopts a sealed design, which makes it difficult to distinguish between indoor and outdoor usage scenarios. In other words, when the usage scenario is clean and tidy indoors, the sealing design is relatively redundant and blocks the beneficial gas exchange between the liquid in the box and the atmosphere;

[0009] 3. The functional design of the device is unreasonable. For example, in the invention of "algae cultivation device", the shell of the incubator is made of reflective material, which makes the box unable to effectively absorb natural light; the key pH sensor is missing, resulting in the inability to effectively monitor the pH that plays a decisive role in algae growth. In the "combined algae cultivation device", the temperature of the box is controlled by the liquid cooling pipe on the outside, but there are no regulations on the shape, size and connection method of the liquid cooling pipe to the box, and the heat conduction efficiency of the liquid cooling pipe is low. At the same time, the cultivation device lacks the control function of light and pH, making it difficult to accurately control and optimize the growth conditions of algae.

[0010] 4. The culture device lacks water circulation function, resulting in the inability to purify harmful substances produced during algae growth in a timely manner;

[0011] 5. The lighting function of the culture device is single and cannot be adjusted to the wavelength of light most suitable for algae growth.

[0012] Therefore, an indoor microalgae cultivation device is needed to improve the above-mentioned shortcomings. Utility Model Content
