However, the overall integration of the device is poor, and the equipment is relatively independent, so it occupies a large space during the specific experimental operation. In fact, it is not used for quick placement, and the operational flexibility is poor. At the same time, it relies on circulating pipes for connection, which is easy to cause mutual mixing between products. In addition, long-distance pipeline transportation is also prone to product loss, causing other unnecessary losses.

[0004] In order to solve the above problems of the prior art, it is necessary to design a more integrated, simpler and more convenient microalgae harvesting device for bacteria-algae symbiosis. Summary of the invention

The valve 2 includes a first valve, a second valve and a third valve. The top of the valve 2 is provided with a power assist plate.

[0021] like Figure 1 As shown, the reaction barrel 3 is a microalgae culture area, the first culture barrel 4 is a fungus culture area or a bacteria-algae symbiotic culture area, and the second culture barrel 5 is used to collect the culture fluid after symbiosis and perform secondary fungus culture or bacteria-algae symbiotic culture.

[0022] In this embodiment, a first valve is installed between the reaction barrel 3 and the first culture barrel 4, a second valve is installed between the reaction barrel 3 and the second culture barrel 5, and a third valve is installed between the first culture barrel 4 and the second culture barrel 5. The first culture barrel 4 and the second culture barrel 5 are respectively provided with a through hole, and a filter is installed on the through hole.

[0023] like Figure 1 and Figure 3As shown, the device of this embodiment also includes a mounting cover 7, and the tops of the reaction barrel 3, the first culture barrel 4, and the second culture barrel 5 are all clamped with mounting covers 7, and driving components 8 are installed on the mounting covers 7. The driving components 8 are composed of a driving motor and a stirrer, and the stirrers are connected to the driving components 8. The stirrer includes a stirring shaft 6 and a stirring rod 9. The stirring shaft 6 is installed in the center of the barrel perpendicular to the horizontal plane, and one end is connected to the driving motor of the driving assembly; multiple groups of stirring rods 9 perpendicular to the stirring shaft are evenly installed in the length direction of the stirring shaft 6, and the projections of the stirring rods 9 of each two adjacent groups on the horizontal plane are orthogonal.

[0024] like Figure 4 As shown, it also includes a mounting ring 10, the inner side of the mounting cover 7 is provided with a mounting ring 10, the mounting ring 10 is rotatably provided with a light-emitting component 11, the light-emitting component 11 is used to adjust the lighting conditions during the cultivation of bacteria and algae, the left and right sides of the light-emitting component 11 are connected to the first magnetic suction component 12, the outer side of the mounting cover 7 is rotatably provided with a rotating ring 13, and the left and right sides of the rotating ring 13 are connected to the second magnetic suction component 14 that is mutually adsorbed and cooperated with the adjacent first magnetic suction component 12.

[0025] The working process of the device of this embodiment is as follows: when using the device for bacteria and algae cultivation, the device can be directly placed on a working plane. The overall integration of the device is high, the space occupied is small, and the placement is more convenient in actual operation.

[0026] First, add microalgae and fungal culture fluids to the reaction barrel 3 and the first culture barrel 4 respectively, and add spores accordingly, and adjust the temperature of the culture environment at the same time. Then the operator can rely on the rotating ring 13 to drive the second magnetic suction member 14 to move, so that the second magnetic suction member 14 drives the adjacent first magnetic suction member 12 to move, and achieve the effect of quickly adjusting the position of the light-emitting component 11; after the adjustment is completed, let it stand for a certain period of time, and when the culture time is reached, rotate and open the third valve between the first culture barrel 4 and the second culture barrel 5, so that the first culture barrel 4 and the second culture barrel 5 are connected. At this time, the fungal culture fluid in the first culture barrel 4 will continue to flow into the second culture barrel 5, and the fungal products in the first culture barrel 4 will be retained under the action of the filter, and then close the third valve 2; then open the first valve between the reaction barrel 3 and the first culture barrel 4, so that the reaction barrel 3 The microalgae product enters the first culture barrel 4. In the process of the microalgae product entering the first culture barrel 4, other impurities can still be filtered out through the filter element. As the microalgae product enters the first culture barrel 4, the first culture barrel 4 enters the culture state of bacterial algae symbiosis. The operator needs to adjust the temperature and the position of the light-emitting component 11 in time, and then start the drive component 8 to drive the stirring shaft 6 and the stirring rod 9 to mix and stir, so that the bacteria and algae can be fully mixed and symbiotic. After the symbiotic culture is completed, the drive component 8 is closed; then the third valve 2 between the first culture barrel 4 and the second culture barrel 5 is opened, so that the culture liquid can enter the second culture barrel 5, and then the product after the symbiotic culture is completed is discharged through the discharge port. After that, the empty reaction barrel 3 and the second culture barrel 5 are selected according to the situation to culture the corresponding microalgae and fungi. After the culture is completed, the reaction barrel 3 can be connected with the second culture barrel 5 through the second valve, so that the cultured product can quickly enter the second culture barrel 5, so as to carry out the microalgae symbiotic culture again. The operation is more convenient and quick, and the use of independent pipelines for transportation can avoid the problem of doping of the product during transportation.

[0027] In order to improve efficiency, sometimes it is necessary to combine different barrels, which can be achieved by changing the connection position relationship between each valve 2 and each barrel.
