The extraction vessel 1 is equipped with a feed pipe and a liquid inlet pipe at the top. During operation, when cleaning the inside of the extraction vessel 1 is required, the flushing assembly is turned on, and water and cleaning agent are mixed and sprayed onto the inside of the extraction vessel 1. Then, the fastening assembly is used to fix the first rotating frame 13 to the outer wall of the rotating shaft 12. The servo motor 11 is turned on, and it drives the first rotating frame 13, the fixing plate 14, the brush 15, and the spring 16 to rotate. The spring 16 presses against the fixing plate 14, causing the brush 15 to approach the inner wall of the extraction vessel 1. As the brush 15 rotates, it cleans the inside of the extraction vessel. The inner wall of the extraction vessel 1 is cleaned to remove the residue adhering to it, and the wastewater is discharged through the drain pipe at the bottom of the extraction vessel 1. This step, through the arrangement of the first rotating frame 13, the fixed plate 14, the brush 15 and the spring 16, forms the internal cleaning structure of the extraction vessel 1, realizing the function of cleaning the inner wall of the extraction vessel 1. This solves the problem of having to open the extraction vessel 1 and other cumbersome steps when cleaning the extraction vessel 1, improves the cleanliness of the inner wall of the extraction vessel 1, reduces the residue adhering to the inner wall of the extraction vessel 1, and simplifies the cleaning operation.
[0025] like Figure 3 and Figure 4As shown, the fastening assembly includes a first fastening bolt 2, a pressure block 21, and a second fastening bolt 22. The second fastening bolt 22 is threadedly connected to the side wall of the first rotating frame 13 near the rotating shaft 12. The pressure block 21 is rotatably connected to the end of the first fastening bolt 2 away from the rotating shaft 12. During operation, when cleaning, the second fastening bolt 22 is tightened to fix the first rotating frame 13 to the rotating shaft 12, and the first fastening bolt 2 is loosened to move the pressure block 21 away from the side wall of the extraction vessel 1, thus completing the cleaning process. Then, loosen the second fastening bolt 22 to make the first rotating frame 13 rotatably connected to the rotating shaft 12, and at the same time tighten the first fastening bolt 2 to make the pressure block 21 press against the inner wall of the extraction vessel 1, thus fixing the first rotating frame 13 to the inner wall of the extraction vessel 1.

A water source or a cleaning agent mixture is connected and sprayed from the nozzle 31 through the channel inside the rotating shaft 12 and the second rotating frame 3 to clean or pre-treat the inner wall of the extraction vessel 1. When the cleaning water is sprayed from the nozzle 31, the residue adhering to the inner wall of the extraction vessel 1 is washed off. This step, through the arrangement of the second rotating frame 3, the nozzle 31 and the water inlet pipe 32, forms a flushing structure, which realizes the function of uniformly flushing the inner wall of the extraction vessel 1, solving the problem of uneven flushing of the inner wall of the extraction vessel 1 and improving the cleanliness of the inner wall of the extraction vessel 1 after cleaning.

The coating on the surface of stirring rods 4 reduces material adhesion to the surface of stirring rods 4; this step, through the arrangement of stirring rods 4, stirs the material and supercritical fluid, increases the contact area between the material and supercritical fluid, improves the extraction quality, and reduces material adhesion to the surface of stirring rods 4.

[0030] like Figure 4 As shown, the pressure block 21 is made of rubber. During operation, the pressure block 21 is made of rubber to increase the friction with the inner wall of the extraction vessel 1 and reduce the slippage that occurs when the first rotating frame 13 is fixed.
[0031] During operation, when cleaning the inside of the extraction vessel 1 is required, the flushing assembly is turned on, and water and cleaning agent are mixed and sprayed onto the inside of the extraction vessel 1. Then, the first rotating frame 13 is fixed to the outer wall of the rotating shaft 12 using the fastening assembly. The servo motor 11 is turned on, and the servo motor 11 drives the first rotating frame 13, the fixing plate 14, the brush 15, and the spring 16 to rotate. The spring 16 presses against the fixing plate 14, causing the brush 15 to approach the inner wall of the extraction vessel 1. When the brush 15 rotates, it sweeps the inner wall of the extraction vessel 1, removing the residue adhering to the inner wall of the extraction vessel 1. Wastewater is discharged through the drain pipe at the bottom of the extraction vessel 1. During cleaning, the second fastening bolt 22 is tightened to fix the first rotating frame 13 to the rotating shaft 12, and the first fastening bolt 2 is loosened to move the pressure block 21 away from the side wall of the extraction vessel 1. After cleaning, the second fastening bolt 22 is loosened to allow the first rotating frame 13 to rotate and connect with the rotating shaft 12. Simultaneously, tighten the first fastening bolt 2 to press the pressure block 21 against the inner wall of the extraction vessel 1, and fix the first rotating frame 13 to the inner wall of the extraction vessel 1; the water inlet pipe 32 is connected to an external water source, and the water source or cleaning agent mixture is sprayed out from the nozzle 31 through the channel inside the rotating shaft 12 and the second rotating frame 3 to clean or pre-treat the inner wall of the extraction vessel 1. When the cleaning water is sprayed out from the nozzle 31, the residue adhering to the inner wall of the extraction vessel 1 is washed off; when stirring is required, the rotating shaft 12 drives the stirring rod 4 to rotate inside the extraction vessel 1, so that the supercritical fluid and the material are in full contact. The surface of the stirring rod 4 has a coating to reduce the material adhering to the surface of the stirring rod 4; the fixing frame 5 and the support leg 51 support the device; after the support leg 51 is placed in the working area, the pad 6 contacts the ground to absorb the shock of the device; the pressure block 21 is made of rubber to increase the friction with the inner wall of the extraction vessel 1 and reduce the slippage when the first rotating frame 13 is fixed.
