Technical Field

[0001] The invention relates to a microalgae concentration and harvesting device and a processing technology thereof. Background Art

[0002] With the development of society, the application of microalgae has become more and more extensive. Microalgae are a kind of plants with simple structure. They are very small and like to float freely with the seawater. Microalgae generally contain chloroplasts, so they can photosynthesize, produce rich organic matter and release oxygen. Microalgae that are cultivated or produced in large quantities using biotechnology belong to four algae phyla: Cyanobacteria, Chlorophyta, Chrysophyta and Rhodophyta. As the most important primary producers in nature, microalgae have begun to play an important role in food, medicine, cosmetics, fine chemicals and other fields. Microalgae need to be concentrated and harvested after being cultivated and discharged. During the concentrated harvesting, the algae liquid is generally transported to the filter for filtration, and the excess liquid in the microalgae is filtered out, and then the microalgae remaining in the filter are collected. Sometimes the cover is opened for collection, which will cause the internal contamination of the filter, and the algae liquid must be stopped after a period of concentration to collect the microalgae inside the filter, which makes the operation inefficient and cumbersome.

[0021] like Figures 1 to 5 As shown, in order to facilitate the stable up and down movement of the movable adsorption hood 53, further, guide rods 531 are respectively provided on both sides of the upper end of the movable adsorption hood 53; guide cylinders 532 are respectively provided below the inner ends of the positioning ring frame 2; the upper ends of the guide rods 531 are slidably inserted into the inner lower part of the guide cylinder 532. Further, the outer sides of the movable adsorption hood 53 are in contact with the inner walls of the concentrated filter cartridge 4. Further, the telescopic long tube 52 is made of a bellows material. Further, the longitudinal section of the concentrated filter cartridge 4 is a U-shaped structure. Further, a drainage pipe 11 is provided in the middle of the lower end of the external drainage box 1.

[0022] like Figures 1 to 5As shown, a processing technology of a microalgae concentration and harvesting device has the following steps: the microalgae liquid is fed into the lower part of the inner part of the concentration filter cartridge 4 through the feed pipe 3, the liquid is discharged downward from the lower part of the concentration filter cartridge 4, and is discharged from the lower part of the external liquid discharge box 1, the microalgae are blocked and accumulated by the concentration filter cartridge 4, when the accumulated microalgae increase, the microalgae will press the movable adsorption cover 53 upward, and make the movable adsorption cover 53 move upward, when the movable adsorption cover 53 moves upward, it drives the pressure spring 54 to compress upward, and the pressure on the pressure sensor 55 will be increased after the pressure spring 54 is compressed upward, and when the movable adsorption cover 53 moves upward to a certain height, the pressure spring 54 pushes upward.

When the microalgae are sucked and moved downward, the mobile adsorption cover 53 moves downward, thereby driving the pressure spring 54 to extend downward. When a certain distance is reached downward, the pressure signal is sent to the controller 56 through the induction of the pressure sensor 55, and the controller 56 drives the suction pump 57 to stop suction. This reciprocating process is repeated. During the whole process, water and material are continuously separated and the material is automatically discharged. There is no need to stop the operation to take the material, and the operation is efficient.
