[0023] Referring to Figures 1-4 , an embodiment of a DHA algal oil extraction device of the present utility model includes: a bottom plate 1, which serves as the support basis for the entire device. The upper surface of the bottom plate 1 is fixedly connected with a support plate 2, which is used to connect the bottom plate 1 and the top plate 3, providing sufficient support force to enable the top plate 3 to stably install components such as the hydraulic rod 5. The upper surface of the support plate 2 is fixedly connected with a top plate 3, which is used to support and install the hydraulic rod 5. The lower surface of the top plate 3 is fixedly connected with a hydraulic rod 5, which is used to drive the pressing block 6 to perform crushing treatment on the algal bodies. The hydraulic rod 5 is located directly above the outer shell 8. The lower end of the hydraulic rod 5 is fixedly connected with a pressing block 6, which is used to directly act on the algal bodies, and through the pushing of the hydraulic rod 5, crushing and pressing are carried out, causing the algal cell walls to rupture and the algal oil to be released and dissolved in the solvent.

[0024] The upper surface of the bottom plate 1 is fixedly connected with a housing 8. As a closed container, the housing 8 is located between the support plates 2. The lower surface of the housing 8 is fixedly connected with a protective frame 15 for protecting the motor 13 from external interference and damage. The lower surface of the housing 8 is fixedly connected with a motor 13 for providing rotational power. The motor 13 is located inside the protective frame 15. The lower surface of the bottom plate 1 is provided with mounting holes for providing an installation space for the protective frame 15. The protective frame 15 is located inside the mounting holes. The output end of the motor 13 is fixedly connected with a rotating shaft 14 for transmitting the rotational force generated by the motor 13. One end of the rotating shaft 14 away from the motor 13 is fixedly connected with a filter cartridge 7 for performing centrifugal operation.

[0025] The lower bottom wall of the housing 8 is provided with a diversion groove 12 for containing algal oil. Inside the diversion groove 12, an inclined ring 16 is fixedly connected for further guiding the algal oil to flow towards the output pipe 9. The inclined ring 16 is lower at the front and higher at the rear. The side surface of the housing 8 is fixedly connected with an output pipe 9 for outputting the pressed and centrifuged algal oil. The output pipe 9 communicates with the housing 8. The output pipe 9 is located in front of the inclined ring 16. A valve 10 is arranged on the side surface of the output pipe 9 for controlling the output of the algal oil. The upper surface of the housing 8 is provided with a feed inlet 11 for putting algal bodies and solvents into the device. The filter cartridge 7 is located inside the feed inlet 11. A pressing block 6 is located directly above the feed inlet 11. The lower surface of the bottom plate 1 is fixedly connected with support columns 4 for supporting the bottom plate 1. The support columns 4 are located at the four corners of the bottom plate 1.

[0026] Working principle: The screened high oil content algal species are put into the filter cartridge 7 through the feed inlet 11, and an appropriate amount of solvent (such as n - hexane, cyclohexane, etc.) is added. The solvent should be able to effectively dissolve the algal oil. Start the hydraulic rod 5 to push the pressing block 6 downward to crush the algal bodies in the filter cartridge 7. During the crushing process, the algal cell walls are damaged, and the algal oil is released and dissolved in the solvent. Then, lift the pressing block 6 through the hydraulic rod 5 and close the feed inlet 11. At the same time, start the motor 13 to drive the rotating shaft 14 to rotate. The rotation of the filter cartridge 7 generates centrifugal force to effectively separate the algal oil from impurities such as solvents and cell debris, improving the extraction efficiency. The algal oil is extracted through double extraction of pressing and centrifugation. Then, the algal oil flows out from the filter holes on the side surface of the filter cartridge 7, enters the inside of the diversion groove 12, and flows towards the output pipe 9 under the guidance of the inclined ring 16. The design of the inclined ring 16 being lower at the front and higher at the rear enables the algal oil to flow more smoothly towards the output pipe 9. Open the valve 10 on the output pipe 9, and the algal oil flows out of the device.

[0027] The above has described the embodiments of the present utility model in detail with reference to the drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those of ordinary skill in the art to which it pertains, various changes can be made without departing from the gist of the present utility model.
