[0002] An extraction tank is a container that is usually used to store and transport many different kinds of substances, or to extract a target substance from a mixture. Extraction tanks are usually made of corrosion-resistant and pressure-resistant materials, such as stainless steel, fiberglass or other special alloy materials. This tank can be designed in different shapes and sizes to suit different extraction processes and needs.

[0003] CN204656054U discloses a traditional Chinese medicine extraction tank, comprising a first extraction tank with a jacket, a tank cover and a stirring mechanism, wherein the stirring mechanism is composed of a driving motor and a stirring shaft, a liquid inlet, an observation port and an exhaust hole are provided on the top of the first extraction tank, a liquid outlet is provided on the bottom of the first extraction tank, the first extraction tank and the tank cover are detachably connected, the end of the stirring shaft is detachably connected with a connecting piece, and a hollow filter barrel for placing traditional Chinese medicine is also provided in the first extraction tank, and the hollow filter barrel is detachably connected to the connecting piece.

[0004] The above technical solution solves the problem that lightweight medicinal materials are difficult to fully soak and extract completely in traditional Chinese medicine extraction tanks, and the residual medicinal liquid in the drug residue is difficult to collect. However, some effective ingredients may exist in different chemical components, and the residue needs to be re-extracted with different solvents to obtain the target product. The above technical solution can only replace different solvents by completely discharging the extract extracted once and stopping the operation of the extraction tank, which is very troublesome and inefficient.

The first extract is used as a part of the extraction solvent to further directionally extract the residue, thereby realizing an extraction mode in which the first extraction tank softens and extracts the material, and the second extraction tank further directionally extracts the material. Moreover, under the temporary storage effect of the first collecting unit, the first extraction tank and the second extraction tank can work uninterruptedly, which not only improves the extraction efficiency to ensure the complete extraction of the material, but also improves the yield.

[0006] At the same time, the second extraction tank has a cell wall breaking function, which can soften the residue initially extracted by the first extraction tank, dissolve more effective ingredients, and improve the extraction rate of effective ingredients.

[0007] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0008] A device for directional extraction and separation of active ingredients, comprising a first extraction tank, a second extraction tank for re-extracting the residue in the first extraction tank, a first collection unit, a second collection unit, a first condensation and oil removal unit, and a second condensation and oil removal unit, wherein the first condensation and oil removal unit and the second condensation and oil removal unit are respectively used for condensation and reflux of steam in the first extraction tank and the second extraction tank;

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] Example 1

[0021] refer to Figures 1 to 6 , a device for directional extraction and separation of active ingredients, comprising a first extraction tank 1, a second extraction tank 2 for re-extracting the residue of the first extraction tank 1, a first collection unit 3, a second collection unit 4, a first condensation and oil removal unit 5, and a second condensation and oil removal unit 6, wherein the first condensation and oil removal unit 5 and the second condensation and oil removal unit 6 are respectively used for condensation and reflux of steam from the first extraction tank 1 and the second extraction tank 2;

[0022] The first collecting unit 3 is used to collect the first extract of the first extraction tank 1 and transport the first extract to the second extraction tank 2; the second collecting unit 4 is used to collect the second extract of the second extraction tank 2, and a directional extraction unit 26 is provided at the bottom of the second extraction tank 2, and the directional extraction unit 26 is used to break the cell wall.

[0023] In some cases of this embodiment, the directional extraction unit can be various devices that can break the cell walls based on mechanical grinding force, impact force, shear force, etc., such as a high-speed blade with a large shear force, an ultrasonic module based on ultrasonic impact wall breaking, a grinding module based on two grinding sheets that can move in relative opposite directions, etc.

[0024] Under this design, the operator adds materials and extraction solution into the first extraction tank 1, performs the first extraction through the first extraction tank 1, and after the extraction in the first extraction tank 1 is completed, discharges the first extract into the first collecting unit 3, and then transports the residue in the first extraction tank 1 to the second extraction tank 2, and adds another extraction solution into the second extraction tank 2 and transports the first extraction tank 1 to the second extraction tank 2 through the first collecting unit 3, and performs a secondary extraction on the residue. At this time, the operator can add materials and extraction solution to the first extraction tank 1 again to perform a new extraction of the same material, thereby realizing uninterrupted operation of the first extraction tank 1 and the second extraction tank 2, and realizing an extraction mode in which the first extraction tank 1 softens and extracts the material, and the second extraction tank 2 further extracts the material in a directed manner. Under the temporary storage effect of the first collecting unit 3, the first extraction tank and the second extraction tank can also work uninterruptedly, which not only improves the extraction efficiency to ensure the complete extraction of the material, but also improves the yield.

[0025] The specific structures of the first condensation and oil removal unit 5 and the second condensation and oil removal unit 6 have been disclosed in Chinese patent CN214830203U, so no further explanation is given in this embodiment. Those skilled in the art can understand that the first condensation and oil removal unit 5 and the second condensation and oil removal unit 6 used in this embodiment are both those described in the scheme. Their function is also to condense and remove the oil from the steam and then return it to the first extraction tank 1 and the second extraction tank 2.

[0026] In this embodiment, a crushing module 7 is also included, and the crushing module 7 is used to crush the residue in the first extraction tank 1 and then transport it to the second extraction tank 2. After the residue is crushed, the surface area can be increased, the penetration of the extraction solvent can be promoted, the mass transfer resistance can be reduced, and the extraction can be uniform, thereby improving the extraction effect. The crushing module 7 can be a stirring crusher, etc., or the residue can be passed through the crushing module 7 under the action of gravity and then enter the second extraction tank 2.

[0027] In this embodiment, the first collecting unit 3 includes an intermediate tank 31, on which a first input pipe and a first output pipe are provided. The intermediate tank 31 is connected to the first extraction tank 1 through the first input pipe, and the intermediate tank 31 is connected to the second extraction tank 2 through the first output pipe. The first input pipe and the first output pipe are provided with a first pump 32 and a second pump 33, respectively.

[0028] The main function of the intermediate tank 31 is temporary storage. It collects the first extract extracted by the first extraction tank 1 and outputs it according to the required amount in the second extraction tank 2. If there is any excess, it will be stored. When the second extraction tank 2 is working, the first extraction tank 1 is in an empty tank state, and the operator can add material again for extraction. The extracted solution will still be temporarily stored in the intermediate tank 31. When the second extraction tank 2 is finished extracting and extracting new material residue, the first extract can be flexibly output.

[0029] In this embodiment, the second collection unit 4 includes a finished product tank 41, which is provided with a second input pipe and a second output pipe. The finished product tank 41 is connected to the second extraction tank 2 through the second input pipe, and the second output pipe is used to output the second extract in the finished product tank 41. The second input pipe and the second output pipe are respectively provided with a third pump 42 and a fourth pump 43. The purpose of the finished product tank 41 is to collect the target products extracted from the second extraction tank 2 for the second time, and these target products can be output through the second output pipe. Of course, a control valve 44 for controlling the output is also provided on the second output pipe.

[0030] As a further optimization of this embodiment, a detachable filter barrel 11 is provided in the first extraction tank 1, a closable discharge port 12 is provided at the bottom of the first extraction tank 1, at least two first connecting pieces 13 are provided on the inner wall of the first extraction tank 1, and a second connecting piece 14 matching the first connecting piece 13 is provided on the filter barrel 11;

[0031] Under the action of the external lifting force, the filter barrel 11 can connect the first connecting member 13 and the second connecting member 14 in an upward manner to install the filter barrel 11 in the first extraction tank 1, or, in the installed state, the first connecting member 13 and the second connecting member 14 can be separated in an upward and downward manner to bring the filter barrel 11 out of the first extraction tank 1 from the discharge port 12.

[0032] Under this design, when slag discharge is required, the operator opens the discharge port 12, lifts up the filter barrel 11 by an external lifting force, and then moves downward to separate the first connecting member 13 and the second connecting member 14, and separates the filter barrel 11 from the first extraction tank 1, takes out the filter barrel 11, and transports the slag in the filter barrel 11 to the second extraction tank 2;

[0033] The filter barrel 11 is driven upward by an external lifting force, and the first connecting member 13 and the second connecting member 14 are connected, and the filter barrel 11 is reinstalled into the first extraction tank 1.

[0034] Of course, it is not ruled out that the staff can feed materials in this way, that is, first take the filter barrel 11 out of the first extraction tank 1, then put the materials into the filter barrel 11, and then install the filter barrel 11 back into the first extraction tank 1. In this way, the installation and disassembly of the filter barrel 11 are very convenient, saving time and effort.

[0035] Preferably, the first connecting member 13 comprises a hook assembly 131 rotatably connected to the first extraction tank 1, and an elastic member 15 is further provided in the first extraction tank 1, and the hook assembly 131 is connected to the elastic member 15;

[0036] The second connecting member 14 includes a clamping block 141, a limiting block 143, and a movable block 142. The clamping block 141 is arranged along the top edge of the filter barrel 11, the limiting block 143 is arranged circumferentially along the side of the filter barrel 11, and the movable block 142 is sleeved on the filter barrel 11 and located between the clamping block 141 and the limiting block 143. The clamping block 141 is provided with a first guide surface 1411, and the movable block 142 is provided with a second guide surface 1421 matching the first guide surface 1411. The first guide surface 1411 and the second guide surface 1421 can be connected to form a guide portion;

[0037] When the filter barrel 11 moves upward, the hook assembly 131 can contact the bottom of the block 141 and support the filter barrel 11; when the filter barrel 11 moves upward for the second time, the hook assembly 131 can contact the movable block 142, and when the filter barrel 11 moves downward, it drives the movable block 142 to move upward until it contacts the block 141, so that the first guide surface 1411 and the second guide surface 1421 are connected, and the hook assembly 131 can detach from the filter barrel 11 along the guide portion.

[0038] Here’s how it works:

[0039] When the filter barrel 11 moves upward, the block 141 first contacts the bottom of the hook assembly 131, and then under the action of the elastic member 15, the block 141 pushes the hook assembly 131 to move away from the axial direction of the first extraction tank 1, which can be understood as the hook assembly 131 opening. When the block 141 rises to a certain height, the elastic member 15 drives the hook assembly 131 to rebound, and at this time the hook assembly 131 can contact the bottom of the block 141 and support the filter barrel 11;

[0040] When the filter barrel 11 goes up for the second time, the movable block 142 first contacts the bottom of the hook assembly 131, and in the same way as the clamping block 141, the hook assembly 131 contacts the second guide surface 1421. Because the movable block 142 is movably sleeved, the hook assembly 131 can drive the movable block 142 to go up when the filter barrel 11 goes down, until the movable block 142 contacts the clamping block 141, and after the first guide surface 1411 and the second guide surface 1421 are connected, the hook assembly 131 can detach from the filter barrel 11 along the guide portion.

[0041] Moreover, the structure of the block 141 and the movable block 142 allows the filter barrel 11 to be stuck or disengaged without alignment, and the limit block 143 can limit the downward movement of the movable block 142. In this way, the upward installation is realized, and the convenient disassembly and assembly method of the secondary upward combined with downward disassembly is realized.

[0042] The elastic member 15 can be a spring or a torsion spring.

[0043] In this embodiment, the first guide surface 1411 is a first inclined surface, and the second guide surface 1421 is a second inclined surface. The highest point of the second inclined surface can be connected with the lowest point of the first inclined surface. When the second inclined surface is connected with the first inclined surface, the hook assembly 131 can move from the first inclined surface to the second inclined surface until it is separated from the filter barrel 11. The first guide surface 1411 and the second guide surface 1421 are connected to form a guide portion. When the filter barrel 11 moves downward, the hook assembly 131 has no fixed point, so that the hook assembly 131 and the filter barrel 11 are separated.

[0044] In this embodiment, a third inclined surface 1311 is provided at the bottom of the hook assembly 131 . When the block 141 or the movable block 142 contacts the third inclined surface 1311 , the third inclined surface 1311 is used to guide the hook assembly 131 to move away from the axis of the first extraction tank 1 .

[0045] Under the action of the third inclined surface 1311, whether it is the clamping block 141 or the movable block 142, after contacting the third inclined surface 1311, it is easier to push the third inclined surface 1311 to move away from the axial direction of the first extraction tank 1, so that the hook assembly 131 is easier to clamp the clamping block 141 or the movable block 142.

[0046] As a further optimization of this embodiment, a guide block 16 is further provided in the first extraction tank 1 and is arranged in a ring along the inner wall of the first extraction tank 1. The guide block 16 is located above the first connecting member 13 and is provided with a fourth inclined surface 161 inclined downward along the axial direction of the first extraction tank 1.

[0047] During the extraction process, it is inevitable that materials with lighter weight will float up as the liquid level rises. In order to allow most of these floating materials to return to the filter barrel 11 when the liquid level drops, a guide block 16 is added, and a fourth inclined surface 161 is provided on the guide block 16. The fourth inclined surface 161 can provide a guiding function to guide the material to the axis of the first extraction tank 1, that is, to guide it back to the filter barrel 11.

[0048] In this embodiment, the first extraction tank 1 is also provided with a first feeding port 17, a first steam outlet 18, a first reflux port 19, and a first drainage pipe 20; the second extraction tank 2 is provided with a second feeding port 21, a second steam outlet 22, a second reflux port 23, a slag discharge port 24, a stirring unit 25, and a directional extraction unit 26, and the directional extraction unit 26 is connected to the bottom of the second extraction tank 2, and the directional extraction unit 26 is provided with a second drainage pipe 261.

[0049] Specifically, the first feed port 17 is used for inputting materials, the first steam outlet 18 is used for discharging steam, the first reflux port 19 is used for reflux after condensation and oil-water separation, and the first liquid discharge pipe 20 is used for conveying the first extract after the first extraction to the intermediate tank 31.

[0050] The second extraction tank 2 is roughly compatible with the first extraction tank 1. The second feeding port 21 can be used to feed slag and extraction solvent. The second steam outlet 22 and the second reflux port 23 have the same function as the first extraction tank 1, so they are not explained in detail in this embodiment. The function of the second slag discharge port 24 in the second extraction tank 2 is to discharge the slag after the secondary extraction, and the directional extraction unit 26 can adopt a directional extraction module such as the one in Chinese patent CN217287238U. Of course, it is not ruled out that the second extraction tank 2 adopts the device disclosed in the patent. After passing through the directional extraction unit 26, the second extract is discharged from the second drainage pipe 261.

[0051] The above is only a preferred embodiment of the present invention. It should be pointed out that a person skilled in the art can make several improvements or modifications without departing from the principle of the present invention. These improvements or modifications should also be regarded as within the protection scope of the present invention.
