[0023] In the utility model, the tank body 1 is used as the main body of the device. When in use, the Chinese medicine stock solution and the extracting liquid are mixed and injected into the interior of the extraction tank 3, and the two positioning frames 2 fix the extraction tank 3. Then, the stirring mechanism 11 is started to rotate at a low speed to stir the Chinese medicine stock solution, and at the same time, the refrigeration device 10 is started to cool the extraction tank 3 inside the tank body 1, so as to achieve the mixed liquid of the Chinese medicine stock solution and the extracting liquid to be cooled to a subcritical state. When the extracting liquid therein dissolves and absorbs the effective components, and the Chinese medicine stock solution that loses the effective components crystallizes, then the movable liquid discharge mechanism 6 is started to move downward, and at this time, the docking groove 5 is opened, and the liquid inside the extraction tank 3 passes through the cooling device 10. The liquid is discharged from the filter plate 4 and discharged through the discharge channel 7, and is discharged into the interior of the receiving box 9 through the annular outlet pipe 8. The crystals are filtered by the filter plate 4 to achieve solid-liquid separation, and the stirring mechanism 11 is closed during the discharge process to avoid breaking the crystals, thereby achieving the advantages of effectively avoiding crystal breakage, and at the same time, achieving better separation effect during solid-liquid separation, improving the purity of the effluent, and facilitating subsequent purification. This solves the problem in the prior art that the raw liquid material still needs to be continuously stirred, which easily breaks up the crystallized solid matter, and as the liquid flows out, the impurity content of the effluent is too high, increasing the difficulty of the subsequent purification process and causing the purity of the finished product to be low.

[0025] In the utility model, the lifting seal block 62 is driven to move vertically by starting the hydraulic cylinder 61, so that the lifting seal block 62 maintains a docking seal with the docking groove 5 during the stirring crystallization process. When solid-liquid separation is required, the hydraulic cylinder 61 is started to drive the lifting seal block 62 to descend so that the liquid can pass through the filter plate 4 and flow out to achieve solid-liquid separation.

[0026] See also Figure 3 , wherein: the lifting sealing block 62 is fixedly connected with vertical rods 621 arranged at equal distances, and the top ends of the vertical rods 621 pass through the gaps of the filter screen plate 4 and extend to the top thereof.

[0027] In the utility model, the vertical rod 621 moves synchronously with the lifting sealing block 62, so that after the stirring mechanism 11 stops, crystals can be prevented from clogging the filter screen plate 4, thereby ensuring smooth drainage.
