The external driving device can drive the connecting shaft through the gear or the pulley, and then drive the holding barrel 2. The driving device can be a servo motor, and a gear or a pulley is installed at the driving shaft end of the servo motor.

[0027] See also Figure 1 , the circulating extraction tank 6 is provided with a solvent for extracting effective components of Chinese medicine. When extracting Chinese medicine, firstly, the material to be extracted is added to the centrifugal extraction tank 1, and the extraction solvent is added to the circulating extraction tank 6, the first valve 9 is opened and the second valve 12 is closed, the containing barrel 2 is controlled to rotate at a low speed, and the centrifugal extraction tank 1 and the circulating extraction tank 6 are heated by the jacket at the same time, so that the effective components of Chinese medicine in the centrifugal extraction tank 1 are volatilized and flow to the concentration component through the steam outlet 3, and the concentration component can liquefy, cool and degrease the steam containing the effective components of Chinese medicine, and finally the liquid containing the effective components of Chinese medicine flows into the circulating extraction tank 6 through the feed port 7, and the jacket outside the circulating extraction tank 6 preheats the Chinese medicine liquid again, and enters the centrifugal extraction tank 1 through the discharge port 8 and the reflux port 4 to be centrifugally heated and evaporated again, thereby forming a cycle to achieve high-concentration Chinese medicine liquid extraction.

[0028] After the extraction of Chinese medicine is completed, the second valve 12 is opened. Under the action of the circulating pump 11, the Chinese medicine extract in the centrifugal extraction tank 1 can enter the extract storage tank 10 for storage. After the circulating pump 11 has extracted the Chinese medicine liquid in the centrifugal extraction tank 1, the high-speed rotation of the containing barrel 2 is controlled to separate the residual extract from the Chinese medicine residue, thereby improving the extraction rate and obtaining drier residue.

[0029] The present application separates the process of obtaining a high-concentration Chinese medicine extract by cyclic extraction of Chinese medicine from the process of collecting the Chinese medicine liquid, so that the effective ingredients in the Chinese medicine can be fully extracted. The application has a simple structure, convenient operation and strong practicality.

[0030] In one or more embodiments, the concentration assembly, the circulating extraction tank 6 and the centrifugal extraction tank 1 are sequentially arranged on the frame from top to bottom.

[0031] See also Figure 1 , Figure 2 , Figure 3 Through this arrangement, the steam in the centrifugal extraction tank 1 can automatically enter the concentration component. After the concentration component liquefies the steam, the liquid flows to the circulation extraction tank 6 and the centrifugal extraction tank 1 in turn under the action of gravity, thereby reducing the use of the pump body and reducing the cost of Chinese medicine extraction.

[0032] In one or more embodiments, the concentration component includes a condenser 14, a cooler 15 and an oil-water separator 16 arranged in sequence from top to bottom, wherein the inlet of the condenser 14 is connected to the steam outlet 3, the outlet of the condenser 14 is connected to the inlet of the cooler 15, the outlet of the cooler 15 is connected to the inlet of the oil-water separator 16, and the outlet of the oil-water separator 16 is connected to the feed port 7 of the circulating extraction tank 6.

[0033] See also Figure 1 , Figure 2 , Figure 3 When extracting Chinese medicine, the steam in the centrifugal extraction tank 1 enters the condenser 14 through the pipeline, the steam is liquefied in the condenser 14 and flows to the cooler 15, the cooler 15 cools the Chinese medicine liquid, and the cooled Chinese medicine liquid enters the oil-water separator 16 for degreasing treatment, and then the Chinese medicine liquid passes through the circulation extraction tank 6 and enters the centrifugal extraction tank 1; the concentration component can remove the oil in the Chinese medicine liquid, further achieving the concentration effect of the Chinese medicine liquid, and at the same time, the Chinese medicine is continuously extracted and concentrated through the above-mentioned circulation structure, which can meet the demand for high-concentration extract.

[0036] See also Figure 1 After the extraction of traditional Chinese medicine is completed, there are two ways to store the extract, the first is to store it in the extract storage tank 10, and the second is to store it in the circulation extraction tank 6. When the first way is used to store the extract, the first valve 9 is closed, the second valve 12 is opened, the third valve 17 is closed, and the fourth valve 18 is opened. The liquid in the centrifugal extraction tank 1 flows through the feed port 7 to the circulation extraction tank 6 for storage under the action of the circulation pump 11; when the second way is used to store the traditional Chinese medicine extract, the first valve 9 is opened, the second valve 12 is opened, the third valve 17 is opened, and the fourth valve 18 is closed. Under the action of the circulation pump 11, the extract is pumped into the extract storage tank 10; through this method, the storage volume of the traditional Chinese medicine extract is increased, and the selectivity is high.

[0037] In one or more embodiments, a duplex filter 19 is disposed between the circulation pump 11 and the extraction liquid storage tank 10. Figure 1 The double filter 19 is used to filter the drug residue to prevent the drug residue from being pumped into the extract storage tank 10 by the circulation pump 11.

[0038] In one or more embodiments, a detachable screen that can rotate synchronously with the barrel 2 is installed in the holding barrel 2. The screen can be installed on the holding barrel 2 by means of quick-open bolts. In the holding barrel 2, the screen is used to place the liquid medicine to be extracted; the screen can be used to separate the medicinal materials from the liquid medicine, thereby further avoiding the problem of drug residues in the extract, and at the same time, it is convenient for the staff to remove the drug residues in the centrifugal extraction tank 1.
