A drive shaft 8 is fixed on the rotor of the rotating motor 7. The drive shaft 8 extends downward into the interior of the separation screen box 3. Several connecting rods 9 are fixed at the bottom end of the drive shaft 8. One end of the connecting rod 9 is fixed on the inner wall of the separation screen box 3.

[0027] A feed inlet pipe 6 is provided on the left side of the feed pipe 5. A first drain pipe 10 is provided at the bottom of the separation box 1. The output end of the first drain pipe 10 is connected to the bottom of the concentration box 11. A heating sleeve 12 is fitted on the outer wall of the concentration box 11. A steam inlet pipe and a steam outlet pipe 14 are provided on the outer wall of the heating sleeve 12. The steam inlet pipe is connected to an external steam generator.

[0028] In this embodiment, the medicinal liquid can be first boiled in the separation box 1, and the boiled residue remains in the separation mesh box 3. The medicinal liquid is then transported to the concentration box 11 for concentration, which has a high concentration efficiency. After the boiling is completed, the separation mesh box 3 is rotated by the rotating motor 7, so that the residual medicinal liquid in the residue is discharged into the separation box 1 through the separation mesh box 3 and transported to the concentration box 11.

[0029] In this embodiment, heat-conducting oil is filled between the inner and outer walls of the separation box 1. A heating wire 15 is provided in the heat-conducting oil. The heat-conducting oil is heated by the heating wire 15, thereby realizing the heating and decoction operation of the medicinal liquid.

[0030] A spiral conveyor blade 16 is provided on the drive shaft 8. In this embodiment, the spiral conveyor blade 16 can convey the raw material into the separation mesh box 3.

[0031] An annular limiting plate 17 is provided on the outer wall of the separation box 3. The annular limiting plate 17 is rotated and limited in the first annular limiting groove 18. The first annular limiting groove is fixed on the inner wall of the separation box 1.

[0033] In this embodiment, the rotational limitation of the annular limiting plate 17 in the first annular limiting groove 18 can improve the rotational stability of the separation net box 3, while the rotational limitation of the top of the separation net box 3 in the second annular limiting groove 19 can prevent the dregs from flying out of the separation net box 3.

[0034] Several through holes 20 are provided on the side wall of the first discharge pipe 4; a second discharge pipe 21 is provided at the bottom of the separation box 1 opposite to the first discharge pipe 4, the output end of the first discharge pipe 4 extends downward into the interior of the second discharge pipe 21, and the first discharge pipe 4 is rotatably disposed inside the second discharge pipe 21; a first electric valve 22 is provided on the second discharge pipe 21.

[0038] Working principle: The raw materials are injected into the feed pipe 5 through the feed inclined pipe 6. Under the action of the spiral conveyor blades 16, the raw materials are quickly conveyed to the separation screen box 3. The heating wire 15 is turned on to heat the heat transfer oil, so as to decoct the raw materials and extract their effective components into the medicine liquid. After the extraction is completed, the second electric valve 25 and the infusion pump 26 are turned on to deliver the medicine liquid to the concentration tank 11. During the delivery process, the rotating motor 7 is started to drive the separation screen box 3 to rotate at high speed. Under the action of centrifugal force, the medicine liquid remaining in the dregs is separated into the separation tank 1 and delivered to the concentration tank 11.

[0039] Then, the second electric valve 25 is closed, the first electric valve 22 is opened to discharge the dregs, and high-temperature steam is injected into the heating sleeve 12 through the steam inlet pipe to heat and concentrate the liquid.
