At the same time, the larger impact force between the solution and the solvent increases the extraction speed of the solute. The top of the piston rod 4031 is fixedly mounted with a top plate 4032. The top plate The bottom end of 4032 is fixedly connected to the output end of cylinder 4033, cylinder 4033 is fixedly installed on the top of extraction cylinder 1, a rack 4034 is fixedly installed on one end of top plate 4032, one side of rack 4034 is meshingly connected with gear 4035, gear 4035 is rotatably installed on mounting frame 4036, mounting frame 4036 is fixedly installed on extraction cylinder 1, a liquid inlet control component 405 is installed between gear 4035 and L-shaped tube 402, and a swing driving component 406 is provided between gear 4035 and inner ring 40492.

The limit stopper 4057 is fixedly connected to the back tube 4053. A rotating disk 4058 is coaxially installed on the back of the gear 4035. A guide groove 4059 is provided at an equal angle on the rotating disk 4058. A telescopic rod 40510 is slidably installed inside the guide groove 4059. A pressing block 40511 is fixedly installed at one end of the telescopic rod 40510. The pressing block 40511 1 is provided with a pressure inclined surface 40512, and a second spring 40513 is fixedly installed on one end of the telescopic rod 40510 away from the pressing block 40511, and one end of the second spring 40513 is fixedly connected to the inner wall of the end of the guide groove 4059. When the rotating disk 4058 rotates clockwise, the pressure inclined surface 40512 on the pressing block 40511 and the end of the pressure plate 4056 generate an interaction force, and when the piston rod 4031 moves upward, the rotating disk 4058 is driven to rotate counterclockwise. When the piston rod 4031 moves upward, the rotating disk 4058 is driven to rotate clockwise, so that the pressure inclined surface 40512 is subjected to force to retract the pressing block 40511, so that the L-shaped tube 402 remains in a closed state, preventing the solution in the straight tube 401 from being pressed back into the liquid storage tank, so that the solution can smoothly enter the solvent.

[0024] The swing driving member 406 includes a fixed plate 4061 fixedly mounted on the top of the uppermost inner ring 40492, a ring-shaped iron sheet 4062 is mounted on the top of the fixed plate 4061, an electromagnet 4063 is fixedly mounted on the bottom wall of the L-shaped tube 402, a longitudinal groove 4064 is provided on the top of the straight tube 401, a longitudinal push rod 4065 is movably mounted inside the longitudinal groove 4064, the bottom wall of the longitudinal push rod 4065 contacts the top wall of the fixed plate 4061, a fixed shaft 4066 is eccentrically mounted on the front of the gear 4035, a second connecting rod 4067 is rotatably mounted on the fixed shaft 4066, and the bottom end of the second connecting rod 4067 is hinged to the top of the longitudinal push rod 4065 Installation, the inner ring 40492 is rotatably installed on the limit arc block 40491, and the electromagnet 4063 generates an upward attraction on one side of the annular iron sheet 4062 on the fixed plate 4061, and at the same time, the gear 4035 rotates to drive the longitudinal push rod 4065 to move back and forth longitudinally. Under the joint action of the longitudinal push rod 4065 and the electromagnet 4063, each stirring plate 40495 swings back and forth. When the solution enters the solvent, the stirring plate 40495 rotates and swings back and forth to increase the stirring range and improve the stirring effect. In the process of the solution entering the straight tube 401, the stirring plate 40495 swings back and forth to stir the solvent, thereby improving the extraction effect of the solution entering the solvent.

[0025] Working principle: When working, firstly, an extraction solvent is introduced into the extraction cylinder 1 through the top tube 2, and then the solution to be extracted is stored in the liquid storage tank, and then the cylinder 4033 is turned on, so that the output end of the cylinder 4033 moves back and forth longitudinally; When the output end of the cylinder 4033 rises upward, the piston rod 4031 and the rack 4034 are pulled upward, and the rack 4034 drives the gear 4035 to rotate counterclockwise, and then drives the rotating disk 4058 to rotate counterclockwise, so that the right-angle side of the pressing block 40511 generates an interaction force on the end of the pressure plate 4056. When each pressing block 40511 passes through the pressure plate 4056, it pushes the pressure plate 4056 downward, so that the spherical valve body 4052 rotates, so that the L-shaped tube 402 is connected from top to bottom, so that the solution in the liquid storage tank can enter the straight tube 401 through the L-shaped tube 402 until the piston rod 4031 moves upward to the limit position; When the output end of the cylinder 4033 retracts downward, the piston rod 4031 and the rack 4034 are pulled downward, and the rack 4034 drives the gear 4035 to rotate clockwise, and then drives the rotating disk 4058 to rotate clockwise, so that the pressure inclined surface 40512 of the pressing block 40511 generates an interaction force on the end of the pressure plate 4056. Since the upper part of the pressure plate 4056 is limited by the limit stop rod 4057, the telescopic rod 40510 retracts toward the inside of the guide groove 4059 under the action of pressure, ensuring the smooth rotation of the gear 4035. In this process, the spherical valve body 4052 will not rotate, so that the L-shaped tube 402 is in a disconnected state, and the solution in the liquid storage tank cannot enter the straight tube 401. At the same time, when the piston rod 4031 moves downward, the solution in the straight tube 401 will not be pressed back into the liquid storage tank; When the piston rod 4031 moves downward, pressure is generated on the inner bottom wall of the top cavity 40482, pushing the movable block 40481 to move downward until the movable block 40481 moves below the connecting hole 4046. At this time, the solution enters the annular cavity 4044 through the top hole 40485 and the connecting hole 4046, and is ejected from the spray hole 4045 toward the solvent, so that the solution can be dispersed and contacted with the solvent, thereby improving the effect of the solvent being extracted by the solvent. At the same time, the impact force of the solution entering the solvent is relatively large, thereby improving the effect of the solute being extracted. At the same time, when the solution continuously flows through the inside of the rotating cylinder 40483, an impact force is generated on the fan blade 40484, which pushes the movable block 40481 to rotate continuously, and then drives the liquid inlet cylinder 4041 to rotate continuously, so that the inner ring 40492 outside the liquid inlet cylinder 4041 rotates with the liquid inlet cylinder 4041, and the stirring plate 40495 rotates to stir the solvent, thereby increasing the solute extraction speed; At the same time, as the gear 4035 rotates continuously, the fixed shaft 4066 rotates with the gear 4035, and then pulls the longitudinal push rod 4065 to move back and forth longitudinally through the second connecting rod 4067. Since the inner ring 40492 is rotatably connected to the limit arc block 40491 through the limit arc groove 40493, when the longitudinal push rod 4065 moves downward, it pushes one side of the fixed plate 4061 to rotate downward. When the longitudinal push rod 4065 moves upward, the electromagnet 4063 generates an upward attraction on one side of the annular iron sheet 4062, causing one side of the fixed plate 4061 to rotate upward. The fixed plate 4061 is moved so as to continuously swing in the solvent, thereby driving the uppermost inner ring 40492 to swing back and forth, thereby improving the stirring effect on the solvent and the extraction speed. The first connecting rod 40496 between two adjacent outer rings 40494 drives each inner ring 40492 to swing. When the solution enters the solvent, the stirring plate 40495 rotates and swings back and forth, thereby increasing the stirring range and the stirring effect. When the solution enters the straight tube 401, the stirring plate 40495 swings back and forth to stir the solvent and improve the extraction effect of the solution entering the solvent. After the treatment is completed, the mixed solution is allowed to stand, and after the mixed solution is separated into layers, the two solutions are discharged from the bottom tube 3 respectively. For example, in the extraction of curcumin, the solution is turmeric juice and the solvent is ethanol. During the extraction, curcumin is extracted from the turmeric juice into the ethanol.
