For example, the filter element in the separation kettle or extraction kettle needs to be taken out for cleaning. Before taking out the filter element, the plunger needs to be screwed out. However, due to the large weight of the plunger, it is difficult to screw out the plunger only by manual means.

[0056] A centering cylinder 720, which is removably installed at the central position of the adjustable connecting rod 710. The power device drives the clamping mechanism to rotate along the circumferential direction of the centering cylinder. As Figure 4 shown, a centering concave hole 721 matching the upper part of the plunger is arranged in the centering cylinder 720;

[0057] Clamping blocks 730, which are arranged on opposite sides of the centering cylinder. The clamping blocks are arranged corresponding to the adjustable connecting grooves of the adjustable connecting rod, and the clamping blocks can linearly slide along the adjustable connecting grooves;

[0058] As Figure 3 shown, the clamping block 730 includes:

[0059] A connecting portion 731, on which a bolt is fixed. The bolt passes through the adjustable connecting groove and is matched with a nut;

[0060] A clamping part 732, the clamping part 732 is connected to the connecting part through an extension part 734, and a jack 733 matching the end of the grip rod of the plunger is provided on the side of the clamping part 732.

[0061] When this embodiment is in use, only need to fit the centering cylinder to the upper part of the plunger, then loosen the nut so that the clamping block can slide along the adjustable connecting groove, slide the clamping block so that the grip rod of the plunger fits into the jack, then tighten the nut to keep the clamping block fixed to the adjustable connecting rod, start the power device, and the power device drives the plunger to rotate, so as to screw the plunger out from the upper part of the separation kettle or extraction kettle. It is convenient to use and can easily remove the plunger.

[0062] In this embodiment, the auxiliary tooling may further include a winch 500, and the winch drives the clamping part to move vertically.

[0063] In this embodiment, the auxiliary tooling may further include:

[0064] A housing 400, the housing wraps the outside of the power device, and the winch 500 is connected to the housing through a flexible rope;

[0065] A mounting plate 800, the mounting plate is connected to the power device, and the clamping mechanism is integrally mounted on the lower surface of the mounting plate 800, and the power device drives the mounting plate to move circumferentially along the centering cylinder.

[0066] Lifting the plunger by the winch avoids the disadvantages of high labor intensity and high danger caused by manual handling.

[0067] In this embodiment, a suspension rail can be installed on the top of the factory building, an electric traveling device is arranged on the suspension rail, the above-mentioned winch is installed on the traveling device, the traveling device travels to the position of the separation kettle or extraction kettle, the winch lowers the clamping mechanism to a preset height, fits the centering cylinder to the upper part of the plunger, fits the end of the grip rod into the jack, starts the power device, so as to screw out the plunger, and then listen to the winch just now to drive the plunger to rise, so as to realize the separation of the plunger from the kettle body.

[0068] Embodiment 2:

[0069] Although in Embodiment 1, the plunger can be lifted by setting a suspension rail and a traveling device, there are the following problems with this method: 1. During the entire disassembly process, a downward pressure needs to be applied manually to prevent the plunger from swinging greatly due to its inertia when the plunger is screwed out, which is relatively dangerous; 2. The plunger will swing during the lifting process, and there is a situation of hitting and injuring people; 3. Since the suspension rail is fixed within a certain area range, the tooling can only be used within a certain area range, and the flexibility is relatively low.

[0070] Therefore, to solve the above technical problems, as Figure 5, 6 As shown, the auxiliary tooling may further include a fixed vertical frame 100. A guiding groove 420 is provided on one side of the outer shell. The guiding groove wraps around the outer side of the first vertical rod in the fixed vertical frame, and a guiding wheel that clamps the vertical rod is installed in the guiding groove.

[0071] During the ascending process, since the first vertical rod is wrapped in the guiding groove and the guiding wheel always travels along the surface of the first vertical rod, the movement of the clamping mechanism is guided, thereby preventing the clamping mechanism from shaking during the above process and causing personal injury, and improving the stability of the clamping mechanism.

[0072] In this embodiment, as Figure 5 , 6 shown, the above-mentioned auxiliary tooling may further include a movable vertical frame 200. The second vertical rod of the movable vertical frame 200 is partially wrapped by the first vertical rod of the fixed vertical frame. The movable vertical frame can slide vertically relative to the fixed vertical frame. A fixing bolt threadedly connected to the first vertical rod is provided at the top of the first vertical rod, and the movable vertical frame and the fixed vertical frame are fixed by the abutment of the tail of the fixing bolt against the surface of the second vertical rod.

[0073] By raising and lowering the movable vertical frame, the ascending height of the clamping mechanism can be adjusted, so as to facilitate adjustment according to the height of the separation kettle or the extraction kettle.

[0074] In this embodiment, the auxiliary tooling may further include a vehicle body 300. The above-mentioned fixed vertical frame and the winch are both fixedly installed on the vehicle body 300. A pulley 210 is installed on the top of the movable vertical frame, and the flexible rope bypasses the pulley 210 and is connected to the connecting ear.

[0075] By pushing the vehicle body, the tooling can be moved on the ground, making the use of the tooling more flexible.

[0076] In this embodiment, connecting ears 410 are provided on the upper and lower surfaces of the outer shell. The auxiliary tooling further includes pulleys. The pulleys are installed on the top of the movable vertical frame and on the vehicle body. The flexible rope bypasses the pulley 210 and is connected to the connecting ear.

[0077] During the sliding process of the outer shell, the flexible rope always remains taut, so that the clamping mechanism can always maintain a force balance state during the working process, thereby improving the stability of the clamping mechanism during rotation.

[0078] By pushing the auxiliary tooling to the position of the supercritical carbon dioxide extraction equipment and lowering the clamping mechanism through the winch, since the flexible rope is connected to the upper surface and the lower surface of the housing, during the lowering process, the flexible rope connected to the upper surface of the housing is released by the winch, and the flexible rope connected to the lower surface of the housing is wound by the winch, so as to keep the flexible rope taut. The situation is opposite during lifting. After lowering to the preset height, which is the height for the centering cylinder to cooperate with the upper part of the plunger, the centering cylinder is fitted to the upper part of the plunger. Then the nut is loosened so that the clamping block can slide along the adjustable connection groove. Slide the clamping block so that the grip rod of the plunger fits into the jack. Then tighten the nut to keep the clamping block fixed with the adjustable connecting rod. Start the power device to drive the plunger to rotate. During the rotation process, the winch will also drive the clamping mechanism to rise slowly until the plunger is screwed out. After being screwed out, the winch drives the clamping mechanism to rise rapidly to lift the plunger.

[0079] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be obvious to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to these embodiments shown herein, but rather to the widest scope consistent with the principles and novel features disclosed herein.
