During the extraction process, when the discharge ports of separators I3 and II4 are opened, a small amount of carbon dioxide will be discharged from the equipment along with the effective substances. To maintain a stable pressure in the circulation system, it is necessary to replenish carbon dioxide from the carbon dioxide liquid tank into the system in a timely manner.

[0032] A carbon dioxide propulsion pump 7 is provided to circulate the carbon dioxide fluid in the circulation system.

[0036] Specifically, the bottom of the filter element 803 passes through the socket 804 and extends to the interior of the shell 801 , and the bottom of the filter element 803 abuts against the bottom of the inner wall of the shell 801 .

[0037] Specifically, both the front and rear sides of the filter element 803 abut against the inner wall of the shell 801 , both the front and rear sides of the filter element 803 are fixedly connected with guide blocks 806 , and both the front and rear sides of the inner wall of the shell 801 are provided with guide grooves 805 .

[0038] During specific implementation, the side of the guide block 806 away from the filter element 803 passes through the guide groove 805 and extends to the inside of the guide groove 805. The guide block 806 and the guide groove 805 are movably connected. The top of the guide block 806 passes through the socket 804 and extends to the inside of the socket 804. The guide block 806 and the socket 804 are movably connected. The top of the guide block 806 is fixedly connected to the bottom of the cover plate 802. Two card slots 807 are symmetrically opened on the left side of the cover plate 802, and a concave plate 808 is fixedly installed on the left side of the top of the shell 801.

[0039] Specifically, a stud 809 is rotatably connected to the right side of the inner wall of the concave plate 808, and the left end of the stud 809 passes through the concave plate 808 and extends to the outside of the concave plate 808 and is fixedly connected to the handle 810. A movable block 811 is threadedly connected to the right side of the surface of the stud 809, and the bottom of the movable block 811 abuts against the bottom of the inner wall of the concave plate 808.

[0040] In actual application: when the filter element 803 needs to be removed, just rotate the handle 810 counterclockwise to drive the stud 809 to rotate, and then the moving block 811 drives the clamping block 812 to move to the left, so that the clamping block 812 is disengaged from the slot 807, and then pull the cover 802 upward to drive the filter element 803 and the guide block 806 to move upward, so that the filter element 803 is disengaged from the socket 804. Through the above steps, the filter element 803 can be easily removed, which makes it easier to maintain, clean or replace the filter element 803.
