Description

Technical Field

[0001] This utility model relates to the field of algae cultivation technology, specifically to an indoor algae seed preparation and high-efficiency screening device. Background Technology

[0002] With the world's population increasing and arable land decreasing, environmental pollution worsening, and desertification accelerating, the food and other agricultural products upon which humanity depends for survival may face a potential crisis of no longer being able to meet human needs. Research over the past century has shown that algae, the primitive green life forms widely distributed on the Earth's surface, are rich in nutrients and possess excellent health benefits, and have been identified by the Food and Agriculture Organization of the United Nations as a green and healthy food for the 21st century. Furthermore, microalgae are among the most photosynthetically efficient primitive plants, with a yield per unit area dozens of times higher than crops, and are the fastest-growing plants in nature. Algae, especially single-celled microalgae, can effectively utilize light energy, CO2, and inorganic salts to synthesize proteins, oils, carbohydrates, and various high-value-added bioactive substances.

[0003] Extensive research has been conducted both domestically and internationally on the large-scale cultivation of algae, exploring various photobioreactors such as flat-plate, tubular, airlift, and open raceway reactors, all of which have been extensively studied, explored, and designed for large-scale algae cultivation. However, cultivation devices for small-scale algae preparation or screening stages are less frequently addressed, particularly lacking intelligent and integrated algae cultivation systems. This makes secondary preparation and rescreening of algae more difficult and results in poor reproducibility.

[0004] Therefore, this project focuses on researching algae cultivation devices and systems that integrate lighting control, ventilation control, and other functions, suitable for indoor small-scale algae strain preparation and screening applications. This will provide a more reliable, reproducible, and easy-to-operate and maintain small-scale device for efficient algae strain preparation and screening. Utility Model Content

[0023] Carbon dioxide gas is introduced into the gas storage unit 4 by the air pump 5. Then, the carbon dioxide gas is controlled by the internal pressure sensor to enter the ventilation pipe 8 through the air guide pipe 10 and the ventilation hose 11. The carbon dioxide gas is introduced into different positions in the culture tray 2 through the individually controllable ventilation valve 9, so the carbon dioxide concentration in the culture tray 2 can be adjusted. Then, the lighting tube 7 provides sufficient light adjustment to regulate the algae cultivation. Moreover, the parameters can be adjusted according to different algae to maintain rapid algae cultivation. The device has a simple structure, is easy to operate, and has a high degree of intelligence.

[0024] The support frame 1 includes a U-shaped frame 101. A crossbar 102 is fixed to the inner side of the U-shaped frame 101 from top to bottom. A movable wheel 103 is fixedly connected to the bottom of the U-shaped frame 101. By setting the structure of the support frame 1, the movable wheel 103 improves the flexibility of the device and facilitates the transfer of the device. At the same time, the crossbar 102 can not only support the U-shaped frame 101, but also facilitate the placement and support of the culture tray 2.

[0025] The culture tray 2 has an H-shaped cross-section. The top and bottom of the culture tray 2 are respectively provided with a culture chamber and a light chamber.

[0030] In practical use, the algae to be cultivated are spread flat on the culture tray 2 in the culture chamber. Then, according to the type of algae, the data in the lighting control unit 18 and the gas storage unit 4 are set. The lighting unit turns on the lighting tube 7 at regular intervals. Then, the lighting tube 7 illuminates the algae on the upper layer from the bottom through the culture tray 2. Then, the air pump 5 introduces carbon dioxide into the gas storage unit 4 through the delivery pipe 6. Subsequently, according to the concentration of carbon dioxide in the culture tray 2, the air valve 9 is opened to introduce the carbon dioxide gas in the gas storage unit 4 into the culture tray 2 to maintain the light and carbon dioxide concentration for algal photosynthesis.
