[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] The utility model provides a technical solution: Figure 1-Figure 5 The shown device is a forced circulation device for extracting liquid, including an extraction tank 1, a discharge outlet 17 fixedly connected to the outside of the extraction tank 1 near the bottom, the discharge outlet 17 is connected to the extraction tank 1, a motor 2 is fixedly connected to the bottom of the extraction tank 1, a rotating rod 3 is fixedly connected to the output end of the motor 2, the rotating rod 3 is arranged inside the extraction tank 1, and a stirring rod 9 is fixedly connected to the outside of the rotating rod 3. There are multiple groups of stirring rods 9 in a circular array outside the rotating rod 3. A circulation component is provided on the outside of the extraction tank 1, and the circulation component includes a circulation pipe 10. The circulation pipe 10 is fixedly connected to the outside of the extraction tank 1 and connected to the inside of the extraction tank 1, and a circulation pump 11 is fixedly connected to the outside of the circulation pipe 10.

[0020] During operation, the Chinese medicine raw materials are placed in the extraction tank 1, and then an appropriate amount of water is injected. The extraction tank 1 is heated by the original structure. At this time, the motor 2 is started, and the motor 2 can drive the rotating rod 3 to rotate, so that the rotating rod 3 drives the stirring rod 9 to quickly mix and extract the medicine and the liquid medicine inside the rotating rod 3, and then the circulation pump 11 drives the liquid medicine to circulate along the circulation pipe 10. After the circulation extraction, it can be discharged from the discharge port 17, and the extracted liquid medicine is collected. In this way, the effect of rapid extraction, stirring and circulation is achieved, which solves the problem of poor extraction effect caused by the previous single decoction structure, improves the extraction effect, and shortens the extraction time.

[0021] See also Figure 3-Figure 5 In the figure, the circulation pipe 10 is abutted against the filter tube 13 at one end away from the extraction tank 1, and the bottom of the filter tube 13 is slidably connected to the sealing cover 4, which is fixedly connected to the top of the extraction tank 1. The filter plate 14 is fixedly connected inside the filter tube 13, and the filter tube 13 is communicated with the sealing cover 4. The medicine feed pipe 5 is fixedly connected inside the sealing cover 4, and the medicine feed pipe 5 is communicated with the extraction tank 1. A spray port 16 is provided at the bottom of the sealing cover 4. There are multiple groups of spray ports 16 in a circular array at the bottom of the sealing cover 4. A medicine filter plate 6 is fixedly connected to the inside of the extraction tank 1 near the top, and a scraper plate 7 is fixedly connected to the outside of the rotating rod 3 near the medicine filter plate 6. The scraper plate 7 is inclined, and a rubber block 8 is fixedly connected to the end of the scraper plate 7 near the medicine filter plate 6.

[0022] During operation, when decocting, Chinese medicine can be directly added into the extraction tank 1 along the medicine inlet pipe 5, and the Chinese medicine will fall on the top of the medicine filter plate 6. At this time, the motor 2 is started to drive the rotating rod 3 to rotate, so that the rotating rod 3 drives the scraper plate 7 and the rubber block 8 to spread the Chinese medicine that falls on the surface of the medicine filter plate 6. At this time, an appropriate amount of water is injected along the medicine inlet pipe 5, and the water is circulated through the circulation pipe 10, so that the Chinese medicine on the surface of the medicine filter plate 6 is repeatedly wetted, thereby accelerating the extraction effect of the Chinese medicine. After being wetted, the Chinese medicine on the surface of the medicine filter plate 6 expands and will move with the rotation of the scraper plate 7, thereby accelerating the extraction efficiency. The repeatedly circulated medicinal residues can be filtered and collected through the filter tube 13 and the filter plate 14, which solves the problem of poor efficiency of circulation when only rotary heating extraction is used, and improves the extraction efficiency.

[0023] See also Figure 1-Figure 3 In the figure, a positioning block 12 is provided on the outside of the filter tube 13, the positioning block 12 is fixedly connected to the top of the sealing cover 4, a pulling block 15 is fixedly connected to the outside of the filter tube 13, a sealing shell 18 is fixedly connected to the bottom of the motor 2, and the sealing shell 18 is fixedly connected to the bottom of the extraction tank 1.

[0024] During operation, the position of the filter tube 13 can be limited by the positioning block 12, and the filter tube 13 can be moved by the pulling block 15 to replace the clogged filter tube 13. The motor 2 can be protected by the sealing shell 18 when it is running, achieving the effect of waterproof protection, solving the problem of damage to the motor 2 caused by the previous exposed structure, and improving the stability of the operation of the motor 2.

[0025] Working principle: Put the Chinese medicine raw materials into the extraction tank 1, then inject an appropriate amount of water, and heat it through the original structure of the extraction tank 1. At this time, start the motor 2, so that the motor 2 can drive the rotating rod 3 to rotate, so that the rotating rod 3 drives the stirring rod 9 to quickly mix and extract the medicine and liquid medicine inside the rotating rod 3, and then let the circulation pump 11 drive the liquid medicine to circulate along the circulation pipe 10. After the circulation extraction, it can be discharged from the discharge port 17, and the extracted liquid medicine is collected. In this way, the effect of rapid extraction, stirring and circulation is achieved, which solves the problem of poor extraction effect caused by the previous use of a single decoction structure, improves the extraction effect, and shortens the extraction time. During decoction, Chinese medicine can be directly added to the extraction tank 1 along the medicine inlet pipe 5, and the Chinese medicine will fall on the top of the medicine filter plate 6. At this time, start the motor 2 to drive the rotating rod 3 to rotate, so that the rotating rod 3 drives the scraping plate 7 and the rubber block 8 to fall on the medicine filter plate. The Chinese medicine on the surface of 6 is spread out, and then an appropriate amount of water is injected along the medicine inlet pipe 5. At this time, the water is circulated through the circulation pipe 10, so that the Chinese medicine on the surface of the medicine filter plate 6 is repeatedly wetted, thereby accelerating the extraction effect of the Chinese medicine. The Chinese medicine on the surface of the medicine filter plate 6 expands after being wetted and will move with the rotation of the scraper plate 7, thereby accelerating the extraction efficiency. The repeatedly circulated medicine residue can be filtered and collected by the filter tube 13 and the filter plate 14, which solves the problem of poor circulation efficiency when only rotating heating extraction is used, and improves the extraction efficiency. The position of the filter tube 13 can be limited by the positioning block 12, and the filter tube 13 can be moved by the pulling block 15 to replace the blocked filter tube 13. The motor 2 can be protected by the sealing shell 18 when it is running, thereby achieving the effect of waterproof protection, solving the problem of damage to the motor 2 caused by the previous exposed structure, and improving the stability of the motor 2 operation.
