[0016] Preferably, an extraction method of an extraction device for extraction is as follows:

[0017] S1. Solution and solvent preparation: The solvent is introduced into the extraction cylinder from the top pipe, and the solution is introduced into the liquid storage tank.

[0018] S2. Solution pressing: The piston rod moves upward under the action of the cylinder, sucking the solution into the straight pipe. When the piston rod moves downward, the solution is pressed into the annular cavity and dispersed and sprayed out from the uniformly arranged spray holes into the solvent.

[0019] S3. Stirring and mixing: When the solution flows through the rotating cylinder, under the impact force, the liquid inlet cylinder and the stirring plate rotate to stir.

[0021] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0022] 1) During operation, through the longitudinal movement of the piston rod provided, the solution to be extracted is continuously pressed into the annular cavity, and is dispersed and sprayed out from the spray holes uniformly arranged on the outer wall of the liquid inlet cylinder towards the solvent, enabling the solution to be dispersed in contact with the solvent, increasing the contact probability between the solution and the solvent, improving the extraction effect of the solvent on the solution in the solution, and at the same time, through the large impact force between the solution and the solvent, increasing the extraction speed of the solute.

[0023] 2) During operation, before the solution enters the annular cavity, it is necessary to push the movable block downward to open the communication hole before it can enter the annular cavity, preventing the solvent from directly entering the straight pipe, facilitating the intermittent entry of the solution into the solvent, improving the contact and extraction effect between the solvent and the solution, and at the same time enabling the solution to continuously pass through the rotating cylinder, facilitating the rotation of the liquid inlet cylinder and the stirring plate to stir the solvent and increasing the extraction speed.

[0024] 3) During operation, the inner ring is installed on the limit arc block by rotation, and the electromagnet generates an upward attraction to one side of the annular iron sheet on the fixed plate. At the same time, the gear rotates to drive the longitudinal push rod to move back and forth longitudinally. Under the joint action of the longitudinal push rod and the electromagnet, each stirring plate swings back and forth. When the solution enters the solvent, the stirring plate rotates and swings back and forth to increase the stirring range and improve the stirring effect. When the solution enters the straight tube, the stirring plate swings back and forth to stir the solvent, thereby improving the extraction effect of the solution entering the solvent;

[0025] 4) During operation, when the piston rod moves upward, it drives the rotating disc to rotate counterclockwise, and the spherical valve body is rotated through the pressure block and the pressure plate, so that the L-shaped tube is connected, which facilitates the solution to enter the straight tube for pre-storage. When the piston rod moves upward, it drives the rotating disc to rotate clockwise, so that the pressure inclined surface is forced to retract the pressure block, so that the L-shaped tube remains in a closed state, preventing the solution in the straight tube from being pressed back into the liquid storage tank, so that the solution can smoothly enter the solvent.

A liquid inlet stirring member 404 is arranged at the bottom end of the straight pipe 401, and a pressure driving member 403 is arranged at the top of the straight pipe 401. The liquid inlet stirring member 404 includes a liquid inlet cylinder 4041 arranged below the straight pipe 401. An annular cavity 4044 is formed inside the liquid inlet cylinder 4041.

The top groove 4047 is communicated with the straight pipe 401, and the inner diameter of the top groove 4047 is the same as that of the straight pipe 401. A liquid storage tank is installed at the top end of the L-shaped pipe 402.

[0041] The rotation control module 4048 includes a movable block 40481 movably installed inside the internal groove 4043. A top cavity 40482 is formed inside the top end of the movable block 40481. A rotating cylinder 40483 is fixedly installed at the top end of the movable block 40481. The rotating cylinder 40483 is communicated with the top cavity 40482, and the outer wall of the rotating cylinder 40483 is in close contact with the inner wall of the top groove 4047. Fan blades 40484 are equally angularly installed on the inner wall of the rotating cylinder 40483. The outer wall of the top end of the movable block 40481 is in close contact with the inner wall of the internal groove 4043 and closes the communication holes 4046. Guide rods 40487 are symmetrically installed on the inner bottom wall of the internal groove 4043. The movable block 40481 is slidably connected to the guide rods 40487. A first spring 40486 is fixedly installed at the bottom end of the movable block 40481.

[0042] The swinging stirring module 4049 includes limiting arc blocks 40491 symmetrically and equidistantly installed on both sides of the liquid inlet cylinder 4041. The outer side of the liquid inlet cylinder 4041 is equidistantly sleeved with an inner ring 40492.

The outer side of the inner ring 40492 is sleeved with an outer ring 40494. Stirring plates 40495 are installed at equal angles between the inner ring 40492 and the outer ring 40494. Before the solution enters the annular cavity 4044, it is necessary to push the movable block 40481 downward to open the communication hole 4046 before it can enter the annular cavity 4044, avoiding the direct entry of the solvent into the straight pipe 401, facilitating the intermittent entry of the solution into the solvent, improving the contact extraction effect between the solvent and the solution, and at the same time enabling the solution to continuously pass through the rotating cylinder 40483, facilitating the driving of the liquid inlet cylinder 4041 and the stirring plates 40495 to rotate, stirring the solvent, and improving the extraction speed.

[0043] The pressure driving member 403 includes a piston rod 4031 movably installed inside the straight pipe 401. The piston rod 4031 longitudinally moves to continuously press the solution to be extracted into the annular cavity 4044 and spray it dispersedly towards the solvent from the spray holes 4045 uniformly arranged on the outer wall of the liquid inlet cylinder 4041, enabling the solution to be dispersed and contact the solvent, improving the extraction effect of the solvent in the solution by the solvent, and at the same time, through the large impact force between the solution and the solvent, improving the extraction speed of the solute. The top end of the piston rod 4031 is fixedly installed with a top plate 4032. The bottom end of the top plate 4032 is fixedly connected to the output end of the air cylinder 4033. The air cylinder 4033 is fixedly installed at the top end of the extraction cylinder 1. One end of the top plate 4032 is fixedly installed with a rack 4034. One side of the rack 4034 is meshed with a gear 4035. The gear 4035 is rotatably installed on the mounting bracket 4036. The mounting bracket 4036 is fixedly installed on the extraction cylinder 1. An inlet liquid control member 405 is installed between the gear 4035 and the L-shaped pipe 402. A swinging driving member 406 is arranged between the gear 4035 and the inner ring 40492.

[0044] The liquid inlet control member 405 includes a spherical valve housing 4051 fixedly installed on the L-shaped pipe 402. A spherical valve body 4052 is rotatably installed inside the spherical valve housing 4051. A back cylinder 4053 is fixedly installed on the back of the spherical valve housing 4051. A rotating shaft 4054 is coaxially installed on the back of the spherical valve body 4052. A volute spring 4055 is installed between the rotating shaft 4054 and the inner wall of the back cylinder 4053. A pressure-receiving plate 4056 is installed on one side of the outer end of the rotating shaft 4054 located outside the back cylinder 4053 and close to the gear 4035. A limiting stop rod 4057 is arranged above the pressure-receiving plate 4056. The limiting stop rod 4057 is fixedly connected to the back cylinder 4053. A rotating disk 4058 is coaxially installed on the back of the gear 4035. Guide grooves 4059 are equally angularly arranged on the rotating disk 4058. A telescopic rod 40510 is slidably installed inside the guide groove 4059. One end of the telescopic rod 40510 is fixedly installed with a pressing block 40511. A pressure-receiving inclined surface 40512 is arranged on the pressing block 40511. One end of the telescopic rod 40510 away from the pressing block 40511 is fixedly installed with a second spring 40513. 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, an interaction force is generated between the pressure-receiving inclined surface 40512 on the pressing block 40511 and the end of the pressure-receiving plate 4056. When the piston rod 4031 moves upward, it drives the rotating disk 4058 to rotate counterclockwise. The spherical valve body 4052 is driven to rotate by the pressing block 40511 and the pressure-receiving plate 4056, so that the L-shaped pipe 402 is communicated, facilitating the solution to enter the straight pipe 401 for pre-storage. When the piston rod 4031 moves upward, it drives the rotating disk 4058 to rotate clockwise, so that the pressure-receiving inclined surface 40512 is stressed to retract the pressing block 40511, keeping the L-shaped pipe 402 in a closed state, preventing the solution in the straight pipe 401 from being back-pressed into the liquid storage tank, and enabling the solution to smoothly enter the solvent.

[0045] The swing drive member 406 includes a fixing plate 4061 fixedly installed at the top end of the uppermost inner ring 40492. An annular iron sheet 4062 is installed at the top end of the fixing plate 4061. An electromagnet 4063 is fixedly installed on the bottom wall of the L-shaped pipe 402. A longitudinal groove 4064 is opened at the top end of the straight pipe 401. A longitudinal push rod 4065 is movably installed inside the longitudinal groove 4064. The bottom wall of the longitudinal push rod 4065 contacts the top wall of the fixing plate 4061. A fixed shaft 4066 is eccentrically installed on the front surface of the gear 4035. A second connecting rod 4067 is rotatably installed on the fixed shaft 4066. The bottom end of the second connecting rod 4067 is hingedly installed with the top end of the longitudinal push rod 4065. The inner ring 40492 is rotatably installed on the limiting arc block 40491. The electromagnet 4063 generates an upward attraction force on one side of the annular iron sheet 4062 on the fixing plate 4061. At the same time, the rotation of the gear 4035 drives the longitudinal push rod 4065 to move longitudinally back and forth. Under the combined 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, increasing the stirring range and improving the stirring effect. During the process of the solution entering the straight pipe 401, the stirring plate 40495 swings back and forth to stir the solvent, improving the extraction effect of the solution entering the solvent.

[0046] Working principle: During operation, first, an extraction solvent is introduced into the extraction cylinder 1 through the top pipe 2. Then, the solution to be extracted is stored in the liquid storage tank. Then, the air cylinder 4033 is started, so that the output end of the air cylinder 4033 moves longitudinally back and forth;

[0047] When the output end of the air cylinder 4033 rises, the piston rod 4031 and the rack 4034 are pulled upward. The rack 4034 drives the gear 4035 to rotate counterclockwise, and then drives the rotating disc 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 receiving plate 4056. When each pressing block 40511 passes through the pressure receiving plate 4056, the pressure receiving plate 4056 is pushed downward, so that the spherical valve body 4052 rotates, making the L-shaped pipe 402 communicate up and down, so that the solution in the liquid storage tank can enter the straight pipe 401 through the L-shaped pipe 402 until the piston rod 4031 moves upward to the limit position;

[0048] When the output end of the air cylinder 4033 retracts downward, it pulls the piston rod 4031 and the rack 4034 to move downward. The rack 4034 drives the gear 4035 to rotate clockwise, and then drives the rotating disc 4058 to rotate clockwise, so that the pressing inclined surface 40512 of the pressing block 40511 generates an interaction force on the end of the pressure receiving plate 4056. Since the upper part of the pressure receiving plate 4056 is limited by the limit stop rod 4057, the telescopic rod 40510 retracts into the guide groove 4059 under the pressure, ensuring the smooth rotation of the gear 4035. During this process, the spherical valve body 4052 does not rotate, making the L-shaped pipe 402 in a disconnected state, and the solution in the liquid storage tank cannot enter the straight pipe 401. At the same time, when the piston rod 4031 moves downward, the solution in the straight pipe 401 will not be pressed back into the liquid storage tank;

[0049] When the piston rod 4031 moves downward, it generates pressure 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 communication hole 4046. At this time, the solution enters the annular cavity 4044 through the top hole 40485 and the communication hole 4046 and shoots out from the spray hole 4045 into the solvent, so that the solution can be dispersed and contact the solvent, improving the solvent extraction effect of the solvent in the solution. At the same time, the impact force of the solution entering the solvent is relatively large, improving the extraction effect of the solute;

[0050] At the same time, when the solution continuously flows through the inside of the rotating cylinder 40483, it generates an impact force on the fan blade 40484, pushing the movable block 40481 to rotate continuously, and then driving 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, making the stirring plate 40495 rotate to stir the solvent and improving the extraction speed of the solute;

[0051] Meanwhile, during the continuous rotation of the gear 4035, the fixed shaft 4066 rotates along with the gear 4035, and then drives the longitudinal push rod 4065 to move longitudinally back and forth through the second connecting rod 4067. Since the inner ring 40492 is rotatably connected to the limiting arc block 40491 through the limiting arc groove 40493, when the longitudinal push rod 4065 moves downward, it pushes one side of the fixing plate 4061 to rotate downward. When the longitudinal push rod 4065 moves upward, due to the upward attraction generated by the electromagnet 4063 on one side of the annular iron sheet 4062, one side of the fixing plate 4061 rotates upward, causing the fixing plate 4061 to continuously swing in the solvent, and then driving the uppermost inner ring 40492 to swing back and forth, improving the stirring effect on the solvent, increasing the extraction speed, and driving each inner ring 40492 to be able to swing through the first connecting rod 40496 between two adjacent outer rings 40494. When the solution enters the solvent, the stirring plate 40495 rotates and swings back and forth, increasing the stirring range and improving the stirring effect. During the process of the solution entering the straight pipe 401, the stirring plate 40495 swings back and forth to stir the solvent, improving the extraction effect on the solution entering the solvent;

[0052] After the treatment, the mixed solution is allowed to stand. After the mixed solution is layered, the two solutions are respectively discharged from the bottom pipe 3. 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.
