[0032] As described in the background art, in the existing countercurrent extraction device during use, due to the gap between the spiral and the inner wall of the spiral tube, the extract is likely to adhere to the inner wall of the spiral tube after contacting the extraction liquid, which is not convenient for subsequent cleaning.

[0033] For the above reasons, please refer to the attached Figure 1 - attached Figure 4 drawings, the present utility model provides an efficient extraction device for Chinese herbal medicine processing, including an extraction frame 2, which is inclined and arranged through a bracket 1;

[0034] A rotating assembly, rotatably installed in the extraction frame 2 for upwardly conveying the solid matter in the extraction frame 2 and spraying the inside of the extraction frame 2.

[0035] Both ends of the extraction frame 2 are respectively provided with a feed inlet 7, a liquid inlet 8, a discharge port 9 and a liquid discharge port 10. The liquid discharge port 10 is arranged at the bottom position of the lowest end of the extraction frame 2, the discharge port 9 is arranged at the bottom position of the highest end of the extraction frame 2, the feed inlet 7 is arranged at the top of the lowest end of the extraction frame 2 and is offset from the liquid discharge port 10, and the liquid inlet 8 is arranged at the top of the highest end of the extraction frame 2 and is offset from the discharge port 9.

[0036] Specifically, the cross-sectional shape of the extraction frame 2 is U-shaped, its top is open and several cover plates 3 are arranged at the open end. The cover plates 3 are detachably and sealedly installed on the top open end of the extraction frame 2. The feed inlet 7 and the liquid inlet 8 are respectively arranged on the cover plates 3 at both ends, and an observation port 6 is also arranged on the cover plate 7 of the feed inlet 7.

[0037] According to the above technical features, the cover plates are provided to facilitate disassembly, so as to facilitate manual cleaning, and the observation port is provided to facilitate observing the internal situation.

[0038] Specifically, the side surface of the cover plate 3 is connected to the outer side surface of the extraction frame 2 by a buckle 5.

[0039] According to the above technical features, setting the buckle connection facilitates firmly connecting the cover plate to the extraction frame and achieving sealing, and also facilitates subsequent removal.

[0040] Specifically, a handle 4 is provided on the cover plate 3.

[0041] According to the above technical features, setting the handle facilitates removing the cover plate.

[0042] Combined with the attached Figure 4 and the attached Figure 5 It can be seen that specifically, the rotating assembly includes a rotating shaft 13, which is rotatably installed in the extraction frame 2 and has both ends extending outside the extraction frame 2 respectively;

[0043] A driving motor 12, which is arranged on the outer side surface at the high end position of the extraction frame 2 and is connected to the rotating shaft 13;

[0044] A spiral blade 14, which is arranged on the rotating shaft 13 inside the extraction frame 2 and has the bottom of the spiral blade 14 close to the inner bottom of the extraction frame 2.

[0045] Specifically, the rotating shaft 13 is provided with a central hole, which extends to the lowermost end of the rotating shaft 13. A water inlet pipe 11 is rotatably installed at the end of the central hole of the rotating shaft 13. Several spray pipes 15 are arranged on the rotating shaft 13 inside the extraction frame 2. The spray pipes 15 are arranged in the gaps of the spiral blade 14 and are communicated with the central hole inside the rotating shaft 13.

[0046] Specifically, the end of the spray pipe 15 is provided with a spherical spray head.

[0047] According to the above technical features, setting the end of the spray pipe as a spherical spray head is to facilitate uniformly spraying water inside the extraction frame, thereby ensuring the cleaning quality and also preventing medicinal materials from entering the spray pipe.

[0048] Please refer to the attached Figure 5 , specifically, a filter disk 16 is further arranged inside the extraction frame 2. The filter disk 16 is arranged between the feed inlet 7 and the drain outlet 10 and is rotatably connected to the rotating assembly.

[0049] According to the above technical features, setting the filter disk is to facilitate filtering the extracted liquid after extraction and prevent the extract from being discharged from the drain outlet along with the extracted liquid.

[0050] During the use of the extraction device, the cover plate 3 is pre-covered on the extraction frame 2 and fixed and sealed by the buckle 5 (sealing can be achieved through a gasket). Subsequently, the crushed medicinal material extract is poured into the extraction frame 2 from the feed inlet 7, and the extraction liquid is poured into the interior of the extraction frame 2 from the liquid inlet 8. Since the extraction frame 2 is inclined, under the action of gravity, the extraction liquid flows downward to contact the medicinal material extract. At this time, the driving motor 12 is started to drive the rotating shaft 13 to rotate. Under the rotation of the spiral blade 14, the medicinal material extract is driven to be conveyed upward, while the extraction liquid flows downward, thus realizing countercurrent extraction. Finally, when the interior needs to be cleaned, the feeding of the extraction liquid and the extract is first stopped. After all the internal liquid is discharged, water is fed into the water inlet pipe 11 through an external water pump and a water source. The clear water enters the central hole of the rotating shaft 13 and is sprayed out from the spray pipe 15, and the interior is cleaned by combining with the rotation of the rotating shaft 13.

However, the embodiment is not intended to limit the scope of the patent application of the present invention. Any equivalent changes or modifications made under the technical spirit disclosed by the present invention shall fall within the scope of the patent covered by the present invention.
