[0022] Preferably, with reference to Figure 3The bottom of the movable piston is fixed to a movable base plate by adhesive or bolts. The movable base plate is slidably connected to the inside of the extraction cylinder along the vertical direction. The movable base plate provides support for the movable piston, making the movement of the movable piston up and down more smooth and stable when the screw drives it. A base is fixed to the movable base plate by welding or integral molding. The bottom of the screw is rotatably connected to the base by bearings. Preferably, the movable piston is sleeved on the outside of the base. This structure makes the connection between the screw and the movable top plate and the movable base plate more stable. When the screw rotates, it will not affect the structure and sealing of the movable piston, thus improving the accuracy of the movable piston lifting the soaking solvent.

[0023] Preferably, the longitudinal section of the filter screen is funnel-shaped. The funnel-shaped structure can better hold the filtered solids, preventing them from falling off the filter screen and improving the accuracy of solid-liquid separation. The screw passes through the bottom of the funnel-shaped structure and is threadedly connected to it. The side of the funnel-shaped structure is provided with multiple filter holes. The filter holes are arranged on the arc-shaped side, giving it a larger filtration area, thereby greatly improving the efficiency of solid-liquid separation.

[0024] Preferably, the top of the filter screen is fixed with a skirt by welding or bolts, and the skirt is slidably connected to the inner wall of the extraction cylinder. This structure makes the overall internal volume of the funnel-shaped filter screen larger, so that the solids screened by the filter screen are more stably accumulated inside the funnel and are not easy to leak or overflow. Solids are not easy to enter the gap between the filter screen and the inner wall of the extraction cylinder, making the up and down movement of the filter screen smoother.

[0025] Preferably, a top cover is movably connected to the top of the extraction cylinder. Specifically, the top cover is detachably connected to the extraction cylinder via a latch. A lifting motor is fixed to the top cover by welding or bolts. A gear is fixed to the output shaft of the lifting motor by welding or bolts. A toothed plate is fixed to the movable top plate by welding or bolts. The toothed plate passes through the top cover and is slidably connected to it. The gear meshes with the toothed plate. In this structure, when the lifting motor rotates, it drives the gear to rotate, causing the meshing toothed plate and the movable top plate to move up and down. This, in turn, drives the movable piston to move up and down rapidly, making the discharge and inlet of the mixture smoother and more efficient, further simplifying the operation steps and improving the smoothness of the soaking and extraction process.

[0026] Preferred, refer to Figure 4 Multiple guide strips are fixed to the inner wall of the extraction cylinder by welding or bolts. The movable top plate, movable piston, and filter screen are all provided with guide holes that slide with the guide strips. This structure allows the movable top plate, movable piston, and filter screen to move up and down only along the guide strips on the inner wall of the extraction cylinder, which improves the stability and smoothness of movement and ensures the accuracy and smoothness of liquid inlet and outlet and solid-liquid separation operations.

[0027] Working Principle: This invention features a vertically sliding top plate and piston inside the extraction cylinder. A filter screen, slidably connected to the extraction cylinder, is positioned between the top plate and piston. After the current soaking and extraction is complete, the filter screen slides upwards, lifting the solids and separating them from the shrimp oil-containing soaking solvent. Then, the moving plate and piston simultaneously slide upwards, raising the soaking solvent to near the shrimp oil outlet pipe, allowing the shrimp oil-containing solvent to drain out. This ensures a cleaner draining of the soaking solvent. After the solvent is drained, the shrimp oil outlet pipe is closed, and the soaking solvent inlet pipe is opened to re-introduce the solvent into the extraction cylinder. The filter screen then slides downwards, allowing the solids on it to re-enter the soaking solvent for further processing. The subsequent soaking and extraction operation allows for simultaneous solid-liquid separation and multiple soaking and extraction operations within the extraction cylinder, greatly simplifying the operation steps, reducing the interval between adjacent soaking and extraction operations, and improving the overall soaking and extraction efficiency. A lifting motor is installed at the bottom of the moving top plate, with a screw on the output shaft of the lifting motor. The screw passes through the filter screen and is threadedly connected to it. The bottom of the screw is rotatably connected to the moving piston. This structure uses the lifting motor and screw to connect the moving top plate and the moving piston, maintaining the synchronicity of their movement. The lifting motor drives the screw to rotate, which in turn drives the filter screen to move up and down under the action of the threaded connection. This makes the solid-liquid separation operation of the extraction mixture more convenient and efficient, further simplifying the operation steps and improving the convenience of repeated soaking and extraction operations.
