[0002] Microalgae are a type of tiny single-celled algae that usually grow in water bodies. They can carry out photosynthesis, absorb carbon dioxide and release oxygen. Microalgae play an important role in the ecosystem and are also widely used in food, feed, biofuel and other fields.

[0003] After searching, Chinese patent announcement number: CN215162619U discloses a self-cleaning microalgae cultivation equipment, including a culture cylinder, a base, a motor, a pump cylinder, a reciprocating screw, a piston and a cleaning device. The top of the culture cylinder is threadedly connected with a cover body, the reciprocating screw and the cleaning device are driven by the motor, the piston is slidably connected in the pump cylinder and meshes with the reciprocating screw, and the cleaning device includes a mounting frame and a brush holder. The beneficial effect of the utility model is that the piston is driven to move in the pump cylinder by the operation of the motor, thereby transporting oxygen-containing air from the outside into the culture cylinder, increasing the aeration speed, and thus providing sufficient oxygen for the growth of microalgae. The motor also drives the cleaning device to rotate during operation, and the cleaning device continuously brushes the inner wall of the culture cylinder to avoid the phenomenon of light blocking caused by the microalgae adhering to the inner wall of the culture cylinder.
