Description

Technical Field

[0001] This application relates to the field of traditional Chinese medicine extraction devices, and in particular to a traditional Chinese medicine extraction device. Background Technology

[0002] Traditional Chinese medicine (TCM) refers to the medicines used in traditional Chinese medicine. TCM is categorized by processing methods into prepared Chinese medicines and raw medicinal materials, and also includes plant-based, animal-based, and mineral-based medicines. Extraction is a crucial step in the TCM manufacturing process. It involves using methods such as decoction and maceration to extract the effective substances from the herbs, thereby maximizing their therapeutic efficacy in clinical treatment.

[0003] Currently, the commonly used equipment for extracting traditional Chinese medicine is the dynamic extraction tank. The dynamic extraction tank can improve the extraction efficiency by stirring, but the medicinal liquid and the residue are easily mixed together, which makes it difficult to clean the residue and separate the medicinal liquid and residue. Therefore, an improvement has been made to a traditional Chinese medicine extraction device. Utility Model Content

[0004] In view of the shortcomings of the prior art, this application provides a traditional Chinese medicine extraction device, which overcomes the shortcomings of the prior art and aims to solve the problem that traditional traditional Chinese medicine extraction equipment is not convenient for cleaning the residue and separating the medicine liquid from the residue.

The reactor is surrounded and heated by a heating unit to ensure uniform temperature rise. The medicinal materials and soaking solution are stirred by a stirring unit to improve extraction efficiency. Automatic separation is achieved by using the separation hole and bottom gap at the bottom of the drug placement cylinder, allowing the liquid medicine to flow into the bottom of the reactor through the separation hole and be discharged through the liquid medicine discharge pipe, while the residue medicine is discharged from the inside of the drug placement cylinder through the residue medicine discharge pipe, which helps to clean the residue medicine and separate the liquid medicine medicine residue medicine.

[0008] By adopting the above technical solution, the gas inside the reactor is extracted through the gas pipe by the vacuum pump to form a negative pressure environment. When the vacuum pump is turned off, the heating unit is used to raise the temperature and generate steam pressure, so that a high pressure environment is formed inside the reactor. This allows for flexible switching between high pressure and negative pressure states to meet the needs of different extraction processes. The pressure gauge monitors the negative pressure value in real time to ensure that the pressure is stable within the set range.

[0011] As a preferred technical solution of this application, the heating unit includes a heating box and a heating coil. A circulating pump is fixedly installed on the top of the heating box. The heating coil is fixedly sleeved on the outer wall of the reactor. The outlet of the heating coil is fixedly connected to the input end of the heating box through a liquid delivery pipe. The inlet of the heating coil is fixedly connected to the output end of the circulating pump through a liquid delivery pipe.

[0012] By adopting the above technical solution, the heating box and the heating coil form a closed loop through the liquid delivery pipe.

The lower end of the dregs discharge pipe 7 extends through the reaction vessel 1 to the outside. A liquid discharge pipe 8 is fixedly connected to one side of the dregs discharge pipe 7 at the bottom of the reaction vessel 1. The bottom of the medicine placement cylinder 5 is connected to the reaction vessel 1. A gap is left between the bottoms of the reactor 1 and the bottom of the medicine container 5 is provided with a separation hole 6. In use, medicinal materials and soaking solution are added into the reactor 1 through the feed port 13. The reactor 1 is wrapped by the heating unit 3 and heated to ensure uniform temperature rise. The medicinal materials and soaking solution are stirred by the stirring unit 4 to improve the extraction efficiency. Automatic separation is achieved by using the separation hole 6 and the bottom gap of the medicine container 5, so that the medicine liquid can flow into the bottom of the reactor 1 through the separation hole 6 and be discharged through the medicine liquid discharge pipe 8, while the medicine residue is discharged from the inside of the medicine container 5 through the medicine residue discharge pipe 7, which helps to clean the medicine residue and separate the medicine liquid and medicine residue. The medicine container 5 is slidably connected to the installation groove 9 by the installation strip 11, which is convenient for disassembly and cleaning.

The connection port 14 is sealed with a gas pipe 15, and the other end of the gas pipe 15 is fixedly connected to a vacuum pump 16. The pressure measuring port 17 is fixedly installed with a pressure gauge 18. In use, the gas inside the reactor 1 is extracted by the vacuum pump 16 through the gas pipe 15 to form a negative pressure environment. When the vacuum pump 16 is turned off, the heating unit 3 is used to heat up and generate steam pressure, so that a high pressure environment is formed inside the reactor 1. This allows for flexible switching between high pressure and negative pressure states to meet the needs of different extraction processes. The pressure gauge 18 monitors the negative pressure value in real time to ensure that the pressure is stable within the set range.

[0027] In this embodiment, as Figure 3 As shown, the external dimensions of the mounting strip 11 are adapted to the internal space dimensions of the mounting groove 9. The top of the mounting groove 9 is fixedly connected with a positioning pin 10, and the bottom of the mounting strip 11 is provided with an insertion hole that matches the positioning pin 10. During use, the mounting strip 11 is limited and fixed inside the mounting groove 9 to prevent the mounting strip 11 from shaking or shifting, thus ensuring the stability of the medicine cartridge 5 during operation.

[0032] The working principle of this utility model is as follows: When using the traditional Chinese medicine extraction device of this application, medicinal materials and soaking solution are added into the reaction vessel 1 through the feed inlet 13. The heat transfer medium is driven by the circulation pump 34 to flow inside the heating coil 31. The heat is evenly transferred to the reaction vessel 1 through the heating coil 31 to ensure uniform heating. The stirring shaft 41 and stirring fan blade 42 are driven by the motor 43 to stir the medicinal materials and soaking solution. The separation hole 6 at the bottom of the medicine container 5 and the bottom gap are used to achieve automatic separation of medicine liquid and medicine residue, so that the medicine liquid can flow into the bottom of the reaction vessel 1 through the separation hole 6. After the extraction is completed, the medicine liquid discharge pipe 8 is opened first to let the medicine liquid be discharged from the medicine liquid discharge pipe 8, and then the medicine residue discharge pipe 7 is opened to let the medicine residue be discharged from the inside of the medicine container 5 through the medicine residue discharge pipe 7.
