The specific extraction process is as follows:
firstly, the medicine powder to be extracted is subpackaged into the medicine bag and placed in the lifting basket 3 according to the requirement, then the worker opens the buckle of the rotary extraction tank upper cover 204 and the rotary extraction tank barrel 202, turns up the rotary extraction tank upper cover 204 under the assistance of the power assisting component, installs the lifting basket 3 into the rotary basket 203 in the rotary extraction tank 2 through the lifting travelling crane and waits for extraction. It should be noted that both the carrier 3 and the spin basket 203 must be secured to prevent accidents during extraction.
Thereafter, the extraction water is added through the solution filling port 410 of the extraction upper tank 4 of the program control box, and during the filling, the breather valve 811 needs to be opened to discharge the air inside the extraction upper tank 4. The extraction water in the upper extraction tank 4 flows into the rotary extraction tank 2 from the solution inlet 223 of the rotary extraction tank through the solution port 411 of the upper extraction tank and the first liquid circulation pipeline 801 under the action of gravity, so that the extraction water is fully contacted with the medicine package in the basket 3.

During the circulation process, the steam heating system also works simultaneously to heat the solution in the upper extraction tank 4 and the rotary extraction tank 2, so that the solution is always kept in a slightly boiling state. Namely, the steam generator respectively transmits high-temperature steam to the first evaporating coil 218 between the inner cylinder and the outer cylinder of the rotary extraction tank 2 and the second evaporating coil 405 between the inner cylinder and the outer cylinder of the upper extraction tank 4 through pipelines, so that the high-temperature steam heats the solution in the rotary extraction tank 2 and the solution in the upper extraction tank 4. Meanwhile, the steam in the first evaporation coil 218 and the second evaporation coil 405 turns into condensed water after being cooled, and the condensed water flows back to the steam generator through the pipeline again, is heated into steam, and is circulated and reciprocated.
Meanwhile, the rotating speed of the driving motor 206 can be adjusted in real time according to the actual extraction requirement when the rotary extraction tank 2 works, so that the rotating speed of the rotating shaft 209 is adjusted through the transmission of the first belt wheel 207 and the second belt wheel 208, namely, the rotating speed of the rotating basket 203 is adjusted, the relative flow between the solution and the medicine package is increased, the solution and the medicine package are in full contact, the extraction efficiency of effective components in the medicine package is further increased, and the problem of medicine precipitation is solved.
When the steam heating system heats the rotary extraction tank 2 and the upper extraction tank 4, the liquid in the two tanks is heated to become steam. The extract vapor in the spin extractor tank 2 moves through a first vapor transfer line 806 into the upper extractor tank 4 and enters the condenser assembly 805 through a second vapor transfer line 807 with the extract vapor in the upper extractor tank 4. The extracting solution is condensed and recovered by the condenser assembly 805 to be extracting solution, then flows back to the upper extracting tank 4 through the extracting solution return line 808, and flows back to the rotary extracting tank 2 through the first liquid circulating line 801, so that the loss of the extracting solution is reduced, and the extracting efficiency is ensured.
After all the extraction is finished, the first pneumatic switch valve 804 is closed, the second pneumatic switch valve 809 is opened, and the extracting solution in the rotary extraction tank 2 enters the liquid storage tank 5 through the infusion pipeline 7 and the filter 810 under the action of the centrifugal pump 803. The extracting solution in the upper extracting tank 4 gradually flows into the rotary extracting tank 2 from the first liquid circulating pipeline 801, and under the continuous action of the centrifugal pump 803, the extracting solutions in the upper extracting tank 4 and the rotary extracting tank 2 finally flow into the liquid storage tank 5. Meanwhile, the functional characteristics of the rotary basket 203 can be utilized to spin-dry the lifting basket 3, and the residual extracting solution in the medicine bag is recycled for the second time.
Finally, the rotary extraction tank 2, the upper extraction tank 4 and the liquid storage tank 5 can be cleaned according to the requirement. Wash water is injected into the rotary extraction tank 2 through the washing pipeline 813, then the extract circulating system makes the wash water circulate in the rotary extraction tank 2 and the extraction upper tank 4, then the first pneumatic switch valve 804 is closed, the second pneumatic switch valve 809 is opened, all the wash water is completely introduced into the liquid storage tank 5 to be washed, and finally the wash water is discharged through the liquid storage tank outlet 503 at the bottom of the liquid storage tank 5.
