[0047] As attached Figure 1 As shown, the present invention provides an intelligent Chinese medicine extraction system, including an extraction tank 10 and a reflux tank. One side of the middle part of the extraction tank 10 is connected to the middle part of the reflux tank through a siphon 15; the siphon 15 is in a "J" shape, with one end connected to the extraction tank 10 and the other end connected to the middle part of the reflux tank.

[0051] The discharge end of the concentration tank 1 is connected to the pill module 5 through the first pipeline 2 , and the first switch valve 3 and the first pump 4 are sequentially installed on the first pipeline 2 along the direction from the concentration tank 1 to the pill module 5 .

[0052] The fifth pipeline 16 is also connected to the discharge end of the liquid storage tank 33 through the fifteenth pipeline 30. The sixth three-way valve, the fourth three-way valve 31, and the liquid inlet pump 32 are sequentially installed on the fifteenth pipeline 30 along the direction from the fifth pipeline 16 to the liquid storage tank 33. The fourth three-way valve 31 is also connected to the reflux tank through the eighteenth pipeline.

[0053] The top of the liquid storage tank 33 is fixedly connected to the first interface of the second condenser 28 through the fourteenth pipeline 29 , and the second interface of the second condenser 28 is fixedly connected to the top of the concentration tank 1 through the fifteenth pipeline 30 .

[0054] The third interface of the second condenser 28 is connected to the tenth pipeline 23 through a branch pipe, the fourth interface is fixedly connected to the third end of the third three-way valve 25 through the thirteenth pipeline 27, and the fifth interface is fixedly connected to the third end of the second three-way valve 20 through the eleventh pipeline 24.

[0055] The first three-way valve 9 and the fifth three-way valve 34 are also fixedly connected to the corresponding exhaust pipes respectively.

[0056] The sixth three-way valve is also fixedly connected to the nineteenth pipeline, and the nineteenth pipeline is used to provide cleaning liquid to the extraction tank 10 and the reflux tank, or to provide solvent to the extraction tank 10 and the reflux tank in an emergency.

[0057] The liquid inlet end of the liquid storage tank 33 is fixedly connected with a twentieth pipeline, and a fifth pump and a third switch valve are sequentially installed on the twentieth pipeline.

[0058] The aforementioned concentration tank 1, reflux tank, liquid storage tank 33, and extraction tank 10 are all equipped with temperature sensors and liquid level sensors; the concentration tank 1, reflux tank, and liquid storage tank 33 are also equipped with heating jackets.

[0059] All the aforementioned pumps, valves, and sensors are electrically connected to the controller and controlled by the controller.

[0060] The aforementioned twelfth pipeline 26 is used to introduce the coolant into the first condenser 22 and the second condenser 28; the tenth pipeline 23 is used to discharge the coolant in the first condenser 22 and the second condenser 28, so that the coolant flows.

[0061] The seventh pipeline 18 and the eleventh pipeline 24 are used to discharge the condensed exhaust gas to the eighth pipeline 19 for centralized treatment.

[0062] The method for extracting Chinese medicine by the above system comprises the following steps:

[0063] S1, adding the pre-treated Chinese medicine to be extracted into the extraction tank 10;

[0064] S2, the controller controls the fourth three-way valve 31 and the sixth three-way valve to operate, so that the sixth pipeline 17 is connected, and then the liquid inlet pump 32 is started to inject the solvent into the extraction tank 10. When the liquid level in the extraction tank 10 reaches the first liquid level, the controller controls the fourth three-way valve 31 to operate and connect with the eighteenth pipeline, and the sixth three-way valve is closed at the same time until the liquid level in the reflux tank reaches a predetermined height.

[0065] The height of the first liquid level is lower than the top position of the siphon tube 15 .

[0066] S3, the second switch valve 14 and the third pump 13 are turned on, and extraction begins. During the extraction process, the temperature in the extraction tank 10 is lower than the temperature in the reflux tank, and the temperature in the reflux tank is maintained at or above the boiling point of the solvent. The temperature in the extraction tank 10 should be lower than the maximum temperature that the components to be extracted can withstand and lower than the boiling point of the solvent.

[0067] The solvent in the reflux tank boils, and the steam enters the first condenser 22 through the seventeenth pipeline. After the solvent is condensed, it enters the extraction tank 10 through the fifth pipeline 16 to dilute the extract formed in the extraction tank 10. When the liquid level in the extraction tank 10 is higher than the top of the siphon 15, part of the extract in the extraction tank 10 will enter the reflux tank due to the siphon effect and be initially concentrated in the reflux tank. At the same time, the generated solvent vapor passes through the first condenser 22 and enters the extraction tank 10 again.

[0068] Since fresh solvent continuously enters the extraction tank 10, the concentration of the extract will decrease, so the leaching effect is better.

[0069] S4, after the extraction is completed, the third pump 13 is turned off, and the heating of the extraction tank 10 and the reflux tank is turned off. The second pump 8 and the fourth pump 35 are turned on, and the extract enters the concentration tank 1 for concentration. The solvent vapor generated during the concentration process enters the second condenser 28 through the fifteenth pipeline 30, and then is condensed into a liquid solvent, and returns to the liquid storage tank 33 through the fourteenth pipeline 29 for reuse.

[0070] S5, after the concentration is completed, the controller opens the first switch valve 3 and the first pump 4 to transport the concentrated extract to the pill module 5 for pill dropping.

[0071] S6, opening the extraction tank 10 to discharge the material.

[0072] The extraction tank 10 may adopt the structure in the prior art, that is, feeding from the top, and after the extraction is completed, opening the bottom tube cover to discharge the material.

[0073] Since the Chinese medicine used for extraction is usually a dried product of a plant, a large amount of solvent will be absorbed during the extraction process. If the existing extraction tank 10 is used, this part of the solvent and the effective ingredients dissolved in the solvent will be discharged together with the Chinese medicine, resulting in waste.

[0074] Therefore, the present invention also provides an extraction tank 10, the structure of which is as shown in the attached Figure 2 To Attachment Fig.11 As shown, it includes a first tank body 39, a first interlayer 37 is fixedly installed on the outside of the first tank body 39, a fifth liquid outlet is fixedly installed on the upper part of the first interlayer 37, and a fifth liquid inlet is installed on the lower part, which is used to pass heat medium into the interlayer to heat and keep the first tank body 39 warm.

Specifically, the first outer ring of the first slewing support 58 is fixedly mounted on the first support 57, the top of the first inner ring is lower than the top of the first outer ring, a limiting ring 69 matching the first inner ring is fixed on the top of the material barrel 59; the bottom of the limiting ring 69 abuts against the top of the first inner ring; and a plurality of latches are inserted between the limiting ring 69 and the first inner ring.

[0088] A second swivel support 76 is fixedly mounted on the bottom of the first tank body 39 via a second support 75. The second outer ring of the second swivel support 76 is fixedly mounted on the second support 75. The top of the second inner ring is lower than the top of the second outer ring. The bottom of the material barrel 59 abuts against the top of the second inner ring, i.e., the material barrel 59 sits on the second inner ring.

[0089] After the extraction is completed, the extract in the extraction tank 10 is sent to the concentration tank 1, and the second pump 8 and the first three-way valve 9 are closed. The second motor 56 is started, and the second motor 56 drives the material barrel 59 and the Chinese medicine inside to rotate to achieve drying. The drying time is pre-set in the controller.

[0090] After the drying is completed, the second motor 56 is turned off. The second pump 8 and the first three-way valve 9 are turned on to transport the extracted liquid to the concentration tank 1.

[0091] In order to improve the extraction rate of the Chinese medicine, a stirring component 60 driven by a first motor 55 is rotatably installed in the material barrel 59. The first motor 55 and the second motor 56 are installed on the same motor base 54.

[0092] The structure of the stirring member 60 is shown in the attached Figure 7 and attached Figure 8 As shown, it includes a stirring shaft 70, the first end of which passes through the connecting tube 62 and the first connecting head 63 at the bottom of the material barrel 59 and is fixedly installed with a special-shaped joint 74.
