Description

Technical Field

[0001] This utility model relates to the field of medicinal material extraction technology, specifically a low-temperature extraction and concentration device for traditional Chinese medicine using hot reflux. Background Technology

[0002] Traditional Chinese medicine (TCM) refers to natural Chinese medicines and their processed substitutes that are guided by TCM theory, have a unique theoretical system and application forms, and are used to prevent and treat diseases as well as have rehabilitation and health care effects. They mainly include plant-based medicines, animal-based medicines, and mineral-based medicines. This device is a device for processing TCMs.

[0003] In the extraction of traditional Chinese medicine (TCM), a mixture of herbs and water is typically heated to generate steam, in which the herbal components dissolve. The active ingredients in this steam are then separated using a low-temperature extraction method. However, in practice, when the steam is piped to a cooling cylinder, it encounters cold air, causing the hot steam to condense and be adsorbed onto the inner wall of the cylinder. This adsorption can make it difficult to completely remove the herbal steam from the inner wall, thus affecting the extraction process and resulting in the ineffective recovery of some herbal components, ultimately wasting the extraction yield. Utility Model Content

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figures 1-4 As shown, a traditional Chinese medicine hot reflux low temperature extraction and concentration device includes a base plate 1 and a cooling cylinder 2 fixed to one side of the top of the base plate 1. The top of the cooling cylinder 2 is provided with a wall scraping mechanism 3, which includes a rotating motor 301, a first bevel gear rod 302 and a second bevel gear rod 303. A liquid outlet hole 4 is opened on one side of the bottom of the inner cavity of the cooling cylinder 2, and a liquid outlet pipe 5 is connected to the bottom flange on one side of the cooling cylinder 2.

[0017] The bottom of the rotating motor 301 is fixedly connected to the top of the cooling cylinder 2. One side of the first bevel gear rod 302 is fixedly connected to the output shaft of the rotating motor 301. One side of the first bevel gear rod 302 is meshed with the second bevel gear rod 303. The bottom of the second bevel gear rod 303 extends through the inner cavity of the cooling cylinder 2 and is fixedly connected to a scraper 304. The surface of the scraper 304 is in contact with the inner wall of the cooling cylinder 2. The bottom of the scraper 304 is rotatably connected to the inner cavity of the cooling cylinder 2 through a bearing. A guide plate 8 for guiding the liquid medicine out is fixedly connected to the bottom of the inner cavity of the cooling cylinder 2. When steam is adsorbed in the inner cavity of the cooling cylinder 2, the rotating motor is started first. 301. The output shaft of the rotating motor 301 drives the first bevel gear rod 302 to rotate. At the same time as the first bevel gear rod 302 rotates, it meshes with the second bevel gear rod 303 to rotate. At the same time as the second bevel gear rod 303 rotates, it drives the scraper 304 to rotate. As the scraper 304 rotates, it removes the Chinese medicine vapor adsorbed on the inner wall of the cooling cylinder 2, so that the Chinese medicine vapor leaves the inner wall of the cooling cylinder 2. Then, the cooled and concentrated medicine liquid is discharged to the surface of the guide plate 8 through the liquid outlet hole 4. Finally, the medicine liquid on the surface is discharged into the inner cavity of the liquid outlet pipe 5 through the liquid outlet pipe 5.

[0018] A steam cylinder 6 is fixed to one side of the top of the base plate 1, and a cover plate 7 is rotatably connected to the top of the steam cylinder 6 via a hinge.

[0019] A conveying pipe 9 is connected to the top flange on one side of the steam cylinder 6. One side of the conveying pipe 9 is connected to the flange of the cooling cylinder 2. Limiting grooves 10 are opened at both ends of one side of the inner cavity of the steam cylinder 6. One side of the inner cavity of the steam cylinder 6 is attached to the filter plate 11, and one side of the filter plate 11 is inserted into the inner cavity of the limiting groove 10. When it is necessary to extract traditional Chinese medicine by steam, the traditional Chinese medicine and pure water are first poured into the inner cavity of the steam cylinder 6. Then the steam cylinder 6 is started. The high temperature inside the steam cylinder 6 causes the traditional Chinese medicine and pure water to boil. The steam emitted from boiling will be transported to the top of the steam cylinder 6. At that time, the valve of the conveying pipe 9 is opened. After the valve is opened, the steam of traditional Chinese medicine will be transported to the inner cavity of the conveying pipe 9. While the steam is being transported to the inner cavity of the conveying pipe 9, the filter plate 11 plays its role in filtering and intercepting impurities in the steam. Then the steam of traditional Chinese medicine is transported to the inner cavity of the cooling cylinder 2 through the conveying pipe 9, thereby effectively extracting traditional Chinese medicine.

[0020] A reinforcing block 305 is fixedly connected to one side of the rotating motor 301, and the bottom of the reinforcing block 305 is fixedly connected to the cooling cylinder 2. By setting the reinforcing block 305, the positioning strength of the rotating motor 301 can be effectively enhanced, thereby ensuring its stability and durability after long-term use.

[0021] Working Principle: First, pour the traditional Chinese medicine and purified water into the inner cavity of the steam cylinder 6, then start the steam cylinder 6. It should be noted that the steam cylinder 6 needs to be connected to a heating device. In the heater, the water or solvent is heated to generate steam. The steam contains the active ingredients to be extracted. This is existing technology, which is clearly known to those skilled in the art and will not be elaborated here. The high temperature inside the steam cylinder 6 causes the traditional Chinese medicine and purified water to boil. The steam emitted from boiling is transported to the top of the steam cylinder 6. At this time, the valve on the delivery pipe 9 is opened. After the valve is opened, the steam containing the traditional Chinese medicine is transported to the inner cavity of the delivery pipe 9. While the steam is being transported to the inner cavity of the delivery pipe 9, the filter plate 11 plays its role in filtering and intercepting impurities in the steam. Then, the steam containing the traditional Chinese medicine is transported to the inner cavity of the cooling cylinder 2 through the delivery pipe 9. When the steam is adsorbed in the inner cavity of the cooling cylinder 2, it should be noted that the cooling cylinder 2 undergoes a preliminary heat transfer process. The heat in the steam is initially absorbed by the cooling medium, such as cold water or coolant. The cooling liquid comes into contact with the steam through the cooling pipe, absorbing the heat of the steam, thus lowering the steam temperature and eventually condensing it into a liquid. This is existing technology, which is clearly known to those skilled in the art. Then, the rotating motor 301 is started, and the output shaft of the rotating motor 301 drives the first bevel gear rod 302 to rotate. At the same time as the first bevel gear rod 302 rotates, it meshes with the second bevel gear rod 303 to rotate. At the same time as the second bevel gear rod 303 rotates, it drives the scraper 304 to rotate. As the scraper 304 rotates, it removes the Chinese medicine vapor adsorbed on the inner wall of the cooling cylinder 2, allowing the Chinese medicine vapor to leave the inner wall of the cooling cylinder 2. Then, the cooled and concentrated medicine liquid is discharged through the liquid outlet 4 to the surface of the guide plate 8. Finally, the medicine liquid on the surface is discharged sequentially into the inner cavity of the liquid outlet pipe 5 through the liquid outlet pipe 5.
