[0024] The mixing assembly includes a driving motor 13, a central rotating shaft 14, a connecting mounting disk 15, a lower connecting shaft 16, a fixed disk 17, a stirring rod 18 and a stirring head 19. The driving motor 13 is installed on the top of the movable ring 11, the central rotating shaft 14 is installed on the output end of the driving motor 13, the connecting mounting disk 15 is installed on the bottom of the central rotating shaft 14, the lower connecting shaft 16 is installed on the bottom of the connecting mounting disk 15, the fixed disk 17 is fixedly installed in the middle of the lower connecting shaft 16, the stirring rod 18 is fixedly installed on the outside of the fixed disk 17, and the stirring head 19 is fixedly installed on the outer end of the stirring rod 18.
[0025] Second rotating shafts 9 are installed at both ends of the rear telescopic frame 8, and three groups of rear telescopic frames are provided. The three groups of rear telescopic frames 8 are in a "Z" shape through the second rotating shafts 9. Second rotating shafts 9 are installed at both ends of the rear telescopic frame 8. Therefore, the rear telescopic frames 8 can be rotated and folded through the second rotating shafts 9, which is convenient for adjusting the angle between the rear telescopic frames 8. After adjustment, the height of the movable ring 11 on the top inside the device can be adjusted, which is convenient for scraping the reactants hanging on the wall of the device from the inside of the device to avoid waste caused by microalgae biomass reaction residues.
[0026] The rear telescopic frames 8 form a rotating structure through the second rotating shaft 9, and the rear telescopic frames 8 form a rotating structure through the second rotating shaft 9 and the movable ring 11. The rear telescopic frames 8 can rotate and adjust the angle inside the device through the second rotating shafts 9 at both ends, so that the overall upward and downward extension can be performed.

During use, the lower connecting shaft 16 and the central rotating shaft 14 are connected together by connecting the mounting plate 15, and the number of the lower connecting shaft 16 inside the device can be adjusted according to the amount of microalgae biomass material inside the device, so that the material inside the device can be stirred more fully, and the thermal cracking reaction is also more sufficient, and four stirring rods 18 are evenly installed on the outside of the fixed plate 17, which can mix the material more fully, make the material heated more evenly, and the cracking reaction more thorough.
