[0001] The utility model relates to the technical field of extraction, and particularly relates to a continuous extraction device. Background Art

[0002] Based on the principle of "like dissolves like", the continuous extraction device utilizes the solubility difference of the solute in two immiscible or almost immiscible solvents to achieve separation. By selecting a suitable solvent, the target compound can be transferred from the original mixture to the solvent phase, thereby separating it from other components.

[0004] In the above extraction device, the partition serves as a barrier to prevent the stirring of the stirrer from affecting the rectifying effect of the subsequent rectifier. However, the stirring of the stirrer causes fluctuations in the solution, which can be transmitted to the rear of the partition through the fluid above the partition, affecting the layering of the subsequent solution. Summary of the Utility Model

[0010] In one embodiment, the partition assembly includes a first partition, a second partition, and a third partition. The first partition and the third partition are connected to the top of the tank body and form a gap for fluid to flow through between them and the bottom of the tank body. The second partition is disposed between the first partition and the third partition, and is connected to the bottom of the tank body and forms a gap for fluid to flow through between it and the bottom of the tank body.

[0011] In one embodiment, it further includes a wire mesh demister. The wire mesh demister is disposed in the stratification chamber and is used for demisting the flowing fluid.

[0012] In one embodiment, the continuous extraction device further includes a stirring assembly. The stirring assembly includes a stirring paddle and a driving member.

[0047] In order to make the purpose, technical solutions and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0048] In order to solve the technical problem that the fluctuation of the solution in the extraction device can be transmitted towards the rear of the partition plate through the fluid above the partition plate, the present utility model provides a continuous extraction device, which can avoid the transmission of the solution fluctuation towards the rear of the partition plate.

[0049] Please refer to Figure 1 , Figure 1 which is a schematic structural diagram of a continuous extraction device in an embodiment of the present utility model. A continuous extraction device includes a tank body assembly 1 and a partition plate assembly 2. The tank body assembly 1 includes a tank body 11 and a medicine pipe 12. The tank body 11 is provided with a first liquid discharge port 11a and a second liquid discharge port 11b. The liquid outlet end of the medicine pipe 12 is placed inside the tank body 11. The partition plate assembly 2 is placed inside the tank body 11 and divides the internal space of the tank body 11 into a mixing chamber 11c and a stratifying chamber 11d which are respectively communicated with the first liquid discharge port 11a and the second liquid discharge port 11b. The partition plate assembly 2 is formed with an overflow channel 2a. The overflow channel 2a communicates the mixing chamber 11c and the stratifying chamber 11d, and at least part of the overflow channel 2a first extends in a direction away from the bottom of the tank body 11 and then in a direction close to the bottom of the tank body 11.

[0050] Specifically, the solution to be extracted and the extractant enter the mixing chamber 11c, where they are mixed. When the liquid level in the mixing chamber 11c reaches a certain height, the mixed solution enters the stratification chamber 11d from the mixing chamber 11c through the overflow channel 2a. Since the overflow channel 2a at least partially extends first away from the bottom of the tank body 11 and then towards the bottom of the tank body 11, when the solution flows through the partition assembly 2, it needs to first flow away from the bottom of the tank body 11 and then towards the bottom of the tank body 11, which can prevent the fluid fluctuations in the mixing chamber 11c from directly passing behind the partition above the partition. After the solution enters the stratification chamber 11d, clarification and stratification occur in the stratification chamber 11d.

[0051] It should be understood that the extractant can enter the mixing chamber 11c through the liquid inlet connector or the reagent pipe 12 on the mixing chamber 11c of the tank body 11, and the solution to be extracted can enter the mixing chamber 11c through the liquid inlet connector or the reagent pipe 12 on the mixing chamber 11c.

[0052] It should be understood that the tank body 11 is also provided with a plurality of connectors respectively communicating with the mixing chamber 11c and the stratification chamber 11d, and the connectors can supply various types of fluids to enter and exit the mixing chamber 11c and the stratification chamber 11d respectively.

[0053] It should be understood that the partition assembly 2 can be two partitions stacked along the height direction, and the cross-section of the partition is triangular. Specifically, in one embodiment, the partition assembly 2 includes a first partition 21, a second partition 22, and a third partition 23. The first partition 21 and the third partition 23 are connected to the top of the tank body 11, and a gap for fluid to flow through is formed between them and the bottom of the tank body 11. The second partition 22 is disposed between the first partition 21 and the third partition 23, and the second partition 22 is connected to the bottom of the tank body 11, and a gap for fluid to flow through is formed between it and the bottom of the tank body 11.

[0054] The first partition 21 can block the fluid from directly flowing through the partition assembly 2 above the second partition 22, so that the fluid needs to flow through the overflow channel 2a of the baffle formed by surrounding between the first partition 21, the second partition 22, and the third partition 23.

[0055] It should be understood that the number of the partition assemblies 2 can also be increased as needed.

[0056] As Figure 1 shown, in one embodiment, the continuous extraction device further includes a wire mesh demister 3. The wire mesh demister 3 is disposed in the stratification chamber 11d for defoaming the flowing fluid.

[0057] By setting the wire mesh demister 3, the wire mesh demister 3 can remove the foam in the flowing fluid, remove the mist in the solution, and avoid the mist affecting the volume of the tank body 11 and the stratification of the solution.

[0058] As Figure 1 shown, in one embodiment, the continuous extraction device further includes a stirring assembly 4. The stirring assembly 4 includes a stirring paddle 41 and a driving member 42. The stirring paddle 41 is rotatably disposed inside the mixing chamber 11c, and the driving member 42 is connected to the stirring paddle 41 and the tank body 11 for driving the stirring paddle 41 to rotate.

[0059] By providing the stirring assembly 4 and starting the driving member 42, the driving member 42 drives the stirring paddle 41 to rotate, and the rotating stirring paddle 41 can cause the extractant and the solution to be extracted in the mixing chamber 11c to be fully mixed.

[0060] It should be understood that the driving member 42 can be a motor, a hydraulic motor, etc.

[0061] As Figure 1 and Figure 3 shown, in one embodiment, the tank body 11 is further provided with a first manhole and a second manhole respectively communicating with the mixing chamber 11c and the stratifying chamber 11d.

[0062] By providing the first manhole and the second manhole, the components in the mixing chamber 11c and the stratifying chamber 11d can be repaired and maintained through the first manhole and the second manhole.

[0063] As Figure 1 and Figure 3 shown, in one embodiment, the tank body assembly 1 further includes a first cover plate 13 and a second cover plate 14. The first cover plate 13 is disposed opposite to the first manhole and is detachably connected to the tank body 11. The second cover plate 14 is disposed opposite to the second manhole and is detachably connected to the tank body 11.

[0064] By providing the first cover plate 13, the first cover plate 13 can control the opening and closing of the first manhole. When it is necessary to repair the components in the mixing chamber 11c through the first manhole, the first cover plate 13 is opened. When mixing is carried out in the mixing chamber 11c, the first manhole is closed through the first cover plate 13. By providing the second cover plate 14, the second cover plate 14 can control the opening and closing of the second manhole. When it is necessary to repair the components in the mixing chamber 11c through the second manhole, the second cover plate 14 is opened. When mixing is carried out in the mixing chamber 11c, the second manhole is closed through the second cover plate 14.

[0065] It should be understood that the first cover plate 13 and the second cover plate 14 can be detachably connected to the tank body 11 by means of bolts, screws, buckles, etc.

[0066] As Figure 1 shown, in one embodiment, the tank body 11 is provided with a sandwich layer 11e.

[0067] By providing an interlayer 11e in the tank body 11, the interlayer 11e can isolate the heat in the tank body 11 from being transferred outward, thus playing a heat preservation role.

[0068] It should be understood that the structure that needs to communicate with the mixing chamber 11c and the stratification chamber 11d passes through the outer layer of the tank body 11 and communicates with the inner layer of the tank body 11, and is sealed between the outer layer of the tank body 11 and the tank body when passing through the outer layer of the tank body 11.

[0069] As Figure 1 shown, in one embodiment, the tank body 11 is further provided with a liquid inlet joint 15 and a liquid discharge joint 16 that communicate with the interlayer 11e.

[0070] By providing the liquid inlet joint 15 and the liquid discharge joint 16, heated liquid or coolant can be injected into the interlayer 11e through the liquid inlet joint 15. Heat exchange is achieved without contact between the liquid in the interlayer 11e and the liquid to be extracted, so that the temperature of the solution in the tank body 11 can be controlled, and the extraction temperature can be controlled. The liquid in the interlayer 11e is discharged from the liquid discharge joint 16.

[0071] Since the tank body 11 is provided with the interlayer 11e, when supporting the tank body 11, it is in direct contact with the outer wall of the tank body 11. Therefore, the interlayer 11e of the tank body 11 is a weak part. For this reason, as Figure 1 and Figure 2 shown, in one embodiment, the tank body assembly 1 further includes at least one reinforcing ring 17. The reinforcing ring 17 is sleeved on the tank body 11 and connects the inner wall and the outer wall of the tank body 11 at the interlayer 11e.

[0072] By providing the reinforcing ring 17, the reinforcing ring 17 connects the inner wall and the outer wall of the tank body 11 at the interlayer 11e, and can strengthen the structural strength of the interlayer 11e of the tank body 11.

[0073] It should be understood that the number of the reinforcing rings 17 can be one, two or more, etc. Specifically, as Figure 1 shown, in one embodiment, the number of the reinforcing rings 17 is two, and the two reinforcing rings 17 are parallel to each other and arranged at intervals.

[0074] Since the reinforcing ring 17 will hinder the fluid from flowing from one end of the interlayer 11e to the other end of the interlayer 11e, for this reason, as Figure 2 shown, in one embodiment, the reinforcing ring 17 is provided with a flow-through hole 17a for the fluid in the interlayer 11e to flow through.

[0075] By providing the flow-through hole 17a, the fluid in the interlayer 11e can flow from one side of the interlayer 11e to the other side of the interlayer 11e through the flow-through hole 17a.

[0076] It should be understood that the overflow hole 17a can be a round hole, an arc-shaped hole, etc. Specifically, as Figure 2 shown, in one of the embodiments, the cross-sectional area of the overflow hole 17a gradually decreases along the flow direction of the fluid in the interlayer 11e.

[0077] When the fluid flows through the overflow hole 17a with a gradually decreasing cross-sectional area, the fluid can smoothly transfer from the large-diameter section to the small-diameter section of the overflow hole 17a, while hindering the fluid from transferring from the small-diameter section to the large-diameter section of the overflow hole 17a, avoiding the reverse transfer of the fluid in the interlayer 11e and the flow not following the preset flow path.

[0078] The specific embodiments of the present invention described above do not constitute a limitation on the protection scope of the present invention. Any other corresponding changes and deformations made according to the technical concept of the present invention should be included in the protection scope of the claims of the present invention.
