Description

Technical Field

[0001] The utility model mainly relates to the technical field of microalgae cultivation, in particular to a microalgae cultivation and collection device. Background Art

[0002] Microalgae refers to those tiny algae groups whose morphology can only be distinguished under a microscope. Microalgae usually refers to the general term for microorganisms that contain chlorophyll a and can perform photosynthesis, and are a type of protists. Microalgae that are cultivated or produced in large quantities using biotechnology belong to four algae phyla: Cyanobacteria, Chlorophyta, Chrysophyta, and Rhodophyta.

[0003] After searching, a microalgae culture collection device disclosed in the announcement number CN218232405U includes a device shell, a control box, a liquid storage tank, a collection net frame and a stirring blade. The lower end of the device shell is provided with a control box, and a controller and a stirring motor are fixedly installed inside the control box. A liquid storage tank is provided on one side of the outside of the device shell, and a liquid infusion tube is connected to the lower end of the liquid storage tank. A collection net frame is provided in the internal chamber of the device shell, and the output end of the stirring motor is connected to a stirring shaft vertically extending into the internal chamber of the device shell, and stirring blades are evenly arranged on the stirring shaft. The present application can use the liquid storage tank to store the nutrient solution required for microalgae culture, and at the same time, the liquid infusion tube can be used to conveniently supplement the nutrient solution required for culture into the device shell. The stirring blade driven by the stirring motor can stir and mix the culture solution in the device shell, so that the nutrients of the added nutrient solution are evenly distributed in the culture solution, which is convenient for accelerating the production and cultivation of microalgae and effectively reducing the time required for microalgae culture.

[0004] In the above technical scheme, the liquid storage tank can be used to store the nutrient solution required for the cultivation of microalgae. At the same time, the infusion tube connected to the lower end of the liquid storage tank can be used to conveniently add the nutrient solution required for the cultivation to the device shell, so that the nutrients of the added nutrient solution are evenly distributed in the culture solution, which is convenient for accelerating the production and cultivation of microalgae, and effectively reducing the time required for the cultivation of microalgae. The microalgae are cultivated centrally through the collection frame, which is convenient for the later removal of the collection frame to complete the collection of microalgae, and solves the problem that the microalgae cultivation and collection device is inconvenient for rapid cultivation. However, during use, the above scheme only provides light source, water source and culture solution to the microalgae, and ignores the fact that temperature and carbon dioxide supply are also important during the growth of microalgae. Therefore, we provide a microalgae cultivation and collection device to solve the defects existing in the above scheme. Utility Model Content
