Description

Technical Field

[0001] This utility model relates to the field of traditional Chinese medicine processing technology, specifically to a vacuum pressure soaking structure for traditional Chinese medicine. Background Technology

[0002] Traditional Chinese medicine emphasizes authentic medicinal materials, which refer to medicinal materials produced in a specific region with specific natural conditions and ecological environment. Because production is relatively concentrated, cultivation techniques, harvesting and processing are also particular, resulting in better quality and efficacy compared to the same medicinal materials produced in other regions. Chinese medicinal materials are diverse in type and source, and each type of medicinal material has a variety of chemical components. Chinese medicinal materials are soaked before use.

[0003] Nowadays, when soaking Chinese medicinal herbs, the method of static soaking under normal pressure is adopted. The air in the pores inside the herbs hinders the penetration of the solvent. This is especially true for dense herbs such as roots and rhizomes, where the active ingredients dissolve slowly and the soaking time can be as long as several hours to several days. Static soaking leads to uneven contact between the solvent and the herbs, resulting in local saturation and reducing the transfer rate of active ingredients. Utility Model Content

[0004] The purpose of this invention is to overcome the defects of the prior art and provide a vacuum pressure soaking structure for Chinese medicinal materials to solve the problems mentioned in the background art.

[0005] A vacuum pressure soaking structure for traditional Chinese medicine includes:

[0006] A soaking tank, the lower part of which is connected to a drain valve;

[0007] A lid is bolted to the top of the soaking tank. A feed inlet is provided in the middle of the top of the lid. A pressure assembly is installed on the left side of the top of the lid, and a vacuum assembly is installed on the right side of the top of the lid.

[0008] A circulation pipeline installed on the soaking tank includes a circulation pipe connected to the side of the soaking tank, a filter pipe fixed between the inlet end of the circulation pipe and the soaking tank, a pump fixed to the side of the soaking tank, an annular pipe fixed to the upper part of the inside of the soaking tank, nozzles uniformly connected in a ring at the lower end of the annular pipe, and a connecting pipe fixedly connected between the inlet end of the filter pipe and the soaking tank. The pump's suction port and discharge port are connected to two sections of the circulation pipe. The outlet end of the circulation pipe extends into the inside of the soaking tank and is connected to the annular pipe. A filter screen is embedded in the inlet end of the filter pipe. The left end of the connecting pipe is in close contact with the outer side of the right end of the filter screen. A cleaning mechanism for cleaning the right end of the filter screen is installed inside the filter pipe.

[0009] Preferably, the soaking tank is provided with an observation window at the front end.

[0010] Preferably, a sealing cap is bolted to the upper end of the feed inlet.

[0011] Preferably, the pressure assembly includes a pressure pipe, a valve, and a pressure gauge. The pressure pipe is fixed to the upper end of the tank cover and communicates with the inside of the soaking tank. The valve is installed on the pressure pipe. The pressure gauge is located on one side of the pressure pipe and installed with the tank cover. An air compressor is connected to the end of the pressure pipe.

[0012] Preferably, the vacuum assembly includes a vacuum tube, a second valve, and a vacuum gauge. The vacuum tube is fixed to the upper end of the tank lid and communicates with the inside of the soaking tank. The second valve is installed on the vacuum tube. The vacuum gauge is located on one side of the vacuum tube and installed with the tank lid. A vacuum pump is connected to the end of the vacuum tube.

[0013] Preferably, the cleaning mechanism includes a fixed frame, a shaft, a turbine, and a lever. Fixed frames are fixed on both the left and right sides inside the filter tube. A shaft is connected between the fixed frames by bearings. A turbine is fixed to the outside of the shaft. The right end of the shaft movably passes through the filter screen and is fixed with a lever. The left end face of the lever is in close contact with the right end face of the filter screen.

[0014] The beneficial effects of this invention are as follows: The vacuum stage (by turning on the vacuum pump) extracts air from the tank and the pores of the medicinal materials, breaking down the permeation resistance and allowing the solvent to quickly permeate the interior of the medicinal materials. The pressurization stage (by turning on the air compressor) uses high pressure to force the solvent into the deep micropores of the medicinal materials, significantly improving the dissolution rate of the active ingredients and shortening the soaking time. As the circulating liquid flows through the filter tube, it impacts the turbine, driving the shaft to rotate. This causes the lever to continuously scrape the surface of the filter screen, automatically removing large impurities and reducing the probability of blockage caused by large impurities. The pump drives the liquid to spray downwards from the nozzle through the annular pipe, ensuring full contact between the medicinal materials and the solvent, thus solving the concentration gradient problem of static soaking.

[0019] like Figures 1-3 As shown, a vacuum pressure soaking structure for traditional Chinese medicine includes:

[0020] The soaking tank 1 has a drain valve 11 connected to its lower part. The drain valve 11 is used to drain the solvent inside the soaking tank 1. A cleaning window is also provided at the lower front end of the soaking tank 1. A window cover is bolted to the cleaning window so that after the solvent is drained, the window cover can be removed to clean the Chinese medicinal materials at the bottom of the soaking tank 1 through the cleaning window.

[0021] A lid 2 is bolted to the upper end of the soaking tank 1. A feed inlet 27 is located in the middle of the upper end of the lid 2. A pressure assembly is installed on the left side of the upper end of the lid 2, and a vacuum assembly is installed on the right side of the upper end of the lid 2. The pressure assembly includes a pressure pipe 21, a valve 22, and a pressure gauge 23. The pressure pipe 21 is fixed to the upper end of the lid 2 and communicates with the interior of the soaking tank 1. The valve 22 is installed on the pressure pipe 21. The pressure gauge 23 is located on one side of the pressure pipe 21 and is installed with the lid 2. An air compressor is connected to the end of the pressure pipe 21. The vacuum assembly includes a vacuum pipe 24, a valve 25, and a vacuum gauge 26. The vacuum pipe 24 is fixed to the upper end of the lid 2 and communicates with the interior of the soaking tank 1. The valve 25 is installed on the vacuum pipe 24. The vacuum gauge 26 is located on the vacuum pipe 24. The vacuum tube 24 is installed on one side and connected to the lid 2. The end of the vacuum tube 24 is connected to a vacuum pump. The inlet 27 is designed to facilitate the addition of Chinese medicinal materials into the soaking tank 1, and also to facilitate the addition of solvent into the soaking tank 1. After the Chinese medicinal materials and solvent are added, the upper end of the inlet 27 is bolted with a sealing cap 28. After using the inlet 27, the sealing cap 28 can be placed on the upper end of the inlet 27 and fixed with bolts. Then, the air in the tank and the pores of the medicinal materials can be extracted through the vacuum stage (by turning on the vacuum pump), breaking the permeation resistance and allowing the solvent to quickly wet the inside of the medicinal materials. Through the pressurization stage (by turning on the air compressor), the high pressure is used to force the solvent into the deep micropores of the medicinal materials, which significantly improves the dissolution rate of the effective ingredients and can shorten the soaking time. In addition, a safety valve can be installed on the soaking tank 1 to prevent overpressure explosion.

[0022] A circulation pipeline 3 is installed on the soaking tank 1. The circulation pipeline 3 includes a circulation pipe 31 connected to the side of the soaking tank 1, a filter pipe 32 fixed between the inlet end of the circulation pipe 31 and the soaking tank 1, a pump 33 fixed to the side of the soaking tank 1, an annular pipe 34 fixed to the upper part of the inside of the soaking tank 1, nozzles 35 evenly connected in a ring to the lower end of the annular pipe 34, and a connecting pipe 36 fixedly connected between the inlet end of the filter pipe 32 and the soaking tank 1. The pump 33's suction port and discharge port are connected to two sections of the circulation pipe 31. The outlet end of the circulation pipe 31 extends into the inside of the soaking tank 1 and is connected to the annular pipe 34. The filter pipe 32's inlet... A filter screen 324 is embedded in the end of the connecting pipe 36, and the left end of the connecting pipe 36 is in close contact with the outer side of the right end of the filter screen 324. A cleaning mechanism for cleaning the right end of the filter screen 324 is installed inside the filter pipe 32. The solvent in the soaking tank 1 can be drawn in through the open connecting pipe 36 by the pump 33, and then discharged into the annular pipe 34 along the connecting pipe 36, the filter pipe 32, and the circulation pipe 31. Then, it is sprayed from top to bottom onto the surface of the Chinese medicinal materials through the nozzle 35 under the annular pipe 34, so that the medicinal materials can fully contact the solvent. During this process, the filter screen 324 in the filter pipe 32 can prevent the Chinese medicinal materials from being drawn in by the pump 33 and affecting the service life of the pump 33.

[0023] The front end of the soaking tank 1 is provided with an observation window 12. The observation window 12 is provided so that the solvent level inside the soaking tank 1 can be easily observed when the solvent is poured in through the feed port 27.

[0024] The cleaning mechanism includes a fixed frame 321, a shaft 322, a turbine 323, and a lever 325. Fixed frames 321 are fixed on both the left and right sides inside the filter tube 32. A shaft 322 is connected between the fixed frames 321 via bearings. A turbine 323 is fixed to the outside of the shaft 322. The right end of the shaft 322 movably passes through the filter screen 324 and is fixed with a lever 325. The left end face of the lever 325 is in close contact with the right end face of the filter screen 324. When the circulating liquid flows through the filter tube 32, it impacts the turbine 323, causing the shaft 322 to rotate. This causes the lever 325 to continuously scrape the surface of the filter screen 324, automatically removing large impurities and reducing the probability of blockage caused by large impurities. Furthermore, a valve 3 can be installed on the circulation pipe 31, located on one side of the outlet end of the filter tube 32, to open and close the circulation pipe 3.

[0025] The air compressor, vacuum pump, and pump 33 mentioned above are all connected to an external power supply and switch.
