[0024] In this embodiment, a filter screen 10 is provided at the bottom of the sliding sleeve 5 , and a plurality of mesh holes are formed at the top of the filter screen 10 and penetrate to the bottom.

[0025] The filter screen 10 can block the raw materials in the housing 1 to prevent the raw materials from moving upward with the supercritical fluid and causing blockage.

[0026] In this embodiment, block-shaped protrusions are provided on both sides of the filter screen 10, and two L-shaped sliding grooves are opened at the bottom of the sliding sleeve 5.

[0027] The filter screen 10 can be stuck in the groove of the sliding sleeve 5 through the block-shaped protrusions on both sides, so that it can be installed into the interior of the housing 1 together with the sliding sleeve 5, and is easy to disassemble and replace.

[0028] In this embodiment, a groove is formed on the top of the sliding sleeve 5 , and a groove is formed on the top of the fixing ring 3 that passes through to the bottom, and the widths of the grooves of the sliding sleeve 5 and the fixing ring 3 match the width of the second crossbar 7 .

[0029] The crossbar 2 7 can slide in the grooves of the sliding sleeve 5 and the fixing ring 3, and is constrained by the grooves of the sliding sleeve 5 and the fixing ring 3 and can only move up and down.

[0030] In this embodiment, circular grooves are formed on both sides of the sliding sleeve 5 , circular holes are formed on both sides of the sleeve 6 , and an annular groove is formed on the inner side of the housing 1 .

[0031] The circular groove of the sliding sleeve 5 can accommodate a part of the limiting ball 9, and the limiting ball 9 can move in the circular hole of the sleeve 6. The sleeve 6 is fixed inside the housing 1 through the limiting ball 9, and the housing 1 is connected to the limiting ball 9 through the annular groove.

[0032] In this embodiment, a funnel-shaped hole is formed on the top of the sliding sleeve 5 and extends to the bottom, and a T-shaped hole is formed on the top of the sleeve 6 and extends to the bottom.

[0033] The funnel-shaped hole of the sleeve 5 can accommodate the passage of supercritical fluid and extract, and the sleeve 6 is connected to the sleeve 5 and the fixing ring 3 through the T-hole.

[0034] In this embodiment, two slide grooves are formed on the inner side of the sleeve 6 , and the shapes of the slide grooves match the guide rail 11 .

[0035] The two guide rails 11 can restrict the movement freedom of the sliding sleeve 5 so that the sliding sleeve 5 can only move along the guidance of the guide rails 11 .

[0036] It should be noted that the utility model is a supercritical fluid extraction device for ginsenosides, which can quickly disassemble the fasteners on the top and simultaneously place the filter screen 10 when in use. The specific implementation method is to hold the crossbar 1 4 and the crossbar 2 7 tightly to move the crossbar 2 7 upward. When the crossbar 2 7 moves upward, the sliding sleeve 5 is driven to move upward, and the sliding sleeve 5 drives the fixing ring 3 to move upward together. When the sliding sleeve 5 moves upward, it drives the guide rail 11 to move. The guide rail 11 can only move along the outer slide groove of the sleeve 6, so the freedom of movement of the sliding sleeve 5 is constrained, so that it can only move up and down, thereby preventing it from being misaligned with the sleeve 6;

[0037] When the fixing ring 3 moves upward, the tension spring 8 is stretched to store force. After the sliding sleeve 5 moves upward to the maximum stroke, its circular groove is aligned with the circular holes on both sides of the sleeve 6, so that one side of the limiting ball 9 can fit with the circular groove of the sliding sleeve 5, so that the other side of the limiting ball 9 can be retracted into the inside of the sleeve 6 when subjected to force.

[0038] When the sleeve 6 is removed from the casing 1, the locking nut 6 is engaged with the locking nut 6 and the locking nut 6 is engaged with the locking nut 6.

[0039] By rotating the filter screen 10, the block-shaped protrusion can slide in the groove at the bottom of the sliding sleeve 5. When the block-shaped protrusion of the filter screen 10 moves to the transition point of the groove, the filter screen 10 can be removed from the bottom of the sliding sleeve 5. In the same way, the filter screen 10 can be installed at the bottom of the sliding sleeve 5, so that the filter screen 10 can be fixed together with the sliding sleeve 5.

[0040] By setting up the fixing mechanism 2, the pressure generated during the operation of the equipment can be withstood, the structural performance of the extraction kettle can be improved, the stability and reliability of the equipment connection can be guaranteed, and the impact of the supercritical fluid on the top of the extraction kettle can be limited to prevent leakage. The filter screen 10 can also be fixed and installed synchronously, making the fixing of the filter screen 10 more convenient.

[0041] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
