Embodiment 1
[0036] see figure 1 , the present embodiment provides a traditional Chinese medicine extraction energy-saving system, including a heating system, a buffer tank 1 and an extraction tank 5;
[0037] The two ends of the buffer tank 1 are respectively connected to the heating system through the first pipeline 21;
[0038] The two ends of the extraction tank 5 are respectively connected in parallel with the two ends of the buffer tank through the second pipeline 22, and a first switch is provided at the corresponding connection between the second pipeline 22 and the first pipeline 21. Reversing valve 8 and second reversing valve 9, wherein the two switching direction channels of the first reversing valve 8 are represented by A1-B1 channel and A1-C1 channel respectively, and the two switching direction channels of the second reversing valve 9 are respectively Represented by A2-B2 channel and A2-C2 channel;
[0039] A circulating pump 2 and a filter 3 are installed on the first pip...
Embodiment 2
[0054] An energy-saving system for extracting traditional Chinese medicine, the system involved in this embodiment is an improvement made on the basis of Example 1, the improvement is: see figure 2 , the extraction tank 5 has a tank body, the tank body is provided with a dosing port 13, a liquid inlet 14, a liquid outlet 15 and a slag discharge port 16, and a bypass branch pipe 17 is provided at the liquid outlet 15, and A second shut-off valve 18 is installed on the bypass branch pipe 17, and the second shut-off valve 18 is used to control the discharge of the medicament extracted; at least one group of shower heads 19 are installed on the top of the inside of the tank, and the shower heads 19 are connected with the liquid inlet. The mouth 14 is connected, wherein the spray head 19 can be provided with 2-3 groups specifically, and the spray head 19 is set to ensure that the medicament of circulation heating and the remaining medicament in the extraction tank 5 are fully conta...
Embodiment 3
[0057] An energy-saving system for extracting traditional Chinese medicine, the system involved in this embodiment is an improvement made on the basis of Embodiment 2, the improvement is: see figure 2 , the extraction tank 5 is also equipped with a vacuum pump 20, the vacuum pump 20 communicates with the tank body of the extraction tank 5 through the air pipe 23, wherein the vacuum pump 20 is used to maintain the extraction tank 5 at a negative pressure, which increases the active ingredients in the traditional Chinese medicine. The driving force to penetrate into the medicine, and make the medicine boil at a lower extraction temperature, thereby further improving the extraction efficiency of traditional Chinese medicine, and effectively avoiding the destruction of the active ingredients in the medicine by high-temperature extraction.
