Embodiment 1

[0036] see figure 1 , this embodiment provides an energy-saving system for continuous extraction of traditional Chinese medicine, including a heating system, a buffer tank and at least two extraction tanks, wherein in this embodiment, three extraction tanks are specifically set, which are successively extraction tanks 51, 52, and 53 ;

[0037] Both ends of the buffer tank 1 are respectively connected to the heating system through first pipelines 211, 212, 213;

[0038] The two ends of each extraction tank are respectively connected in parallel with the two ends of the buffer tank 1 through the second pipeline 221, 222, 223, and the two ends of the second pipeline 221, 222, 223 are connected with the first Corresponding connections of pipelines 211, 212, 213 are provided with first reversing valves 81, 82, 83 and second reversing valves 91, 92, 93;

[0039] Among them, the two switching direction passages of the first reversing valve 81 are represented by A11-B11 passage and ...

Embodiment 2

[0060] This embodiment is based on the energy-saving system described in Embodiment 1, and further improves the extraction tank. see figure 2 , the extraction tank is provided with a dosing port 13 for adding traditional Chinese medicine, a liquid inlet 14 for adding a solvent to the extraction tank or for the medicine return of the heating cycle, a liquid outlet 15 for outputting the extraction medicine, and a At the slag discharge port 16 for discharging medicinal dregs; at least one set of spray heads 19 are installed on the top of the inside of the extraction tank, and the spray heads 19 are connected to the liquid inlet 14, wherein the spray heads 19 can be set in 2-3 groups , and the spray head 19 is set to ensure sufficient heat exchange between the circulating heated medicine and the remaining medicine in the extraction tank, thereby improving the extraction efficiency of traditional Chinese medicine.

[0061] Further, the diameter of the spray opening on the spray h...

Embodiment 3

[0064] This embodiment is based on the energy-saving system described in Embodiment 1-2, which is specifically a traditional Chinese medicine extraction method of the energy-saving system for continuous extraction of traditional Chinese medicine, including:

[0065] S1, adding solvent to the buffer tank;

[0066] S2, closing the first cut-off valve, and switching the first reversing valve and the second reversing valve at the same time, so as to heat the solvent in the buffer tank until the solvent reaches the preset temperature for Chinese medicine extraction;

[0067] S3, add traditional Chinese medicine to each extraction tank, randomly select one of the extraction tanks as the first tank for drug configuration, and open the first cut-off valve corresponding to the first tank, and use the rest of the extraction tanks sorted in the middle and last as the middle Tank and tail tank, waiting for spare;

[0068] S4, perform extraction operation of traditional Chinese medicine o...
