Description

Technical Field

[0001] This utility model relates to the field of traditional Chinese medicine liquid preparation technology, and more specifically, to a continuous production device for traditional Chinese medicine liquid preparations. Background Technology

[0002] Membrane separation technology is a novel filtration and separation technology. This technology uses static pressure difference as the driving force and utilizes the sieving effect of the sieve-like filter medium membrane to achieve separation and purification effects, and can realize the removal of impurities and concentration of traditional Chinese medicine liquid.

[0003] In practical applications, due to the significant differences in the number, size, and chemical properties of particles in different traditional Chinese medicine liquid systems, the filtration and concentration rates and membrane module clogging vary considerably when using the same set of filtration and concentration equipment during production. This makes it difficult to ensure that the processing speed of filtration and impurity removal matches that of the concentration stage, resulting in the inability to achieve stable and continuous production. Utility Model Content

[0004] In view of this, the purpose of this utility model is to propose a continuous production device for traditional Chinese medicine liquid preparations, so as to eliminate the influence of the difference in filtration and concentration speed of different types of medicinal liquids without changing the membrane components, and ensure that the production process is stable and continuous.

[0005] Based on the above objectives, this utility model provides a continuous production device for traditional Chinese medicine liquid preparations, including a filtration device, a buffer device, a concentration device, a first booster pump, a second booster pump, and a controller. The filtration device includes a filter membrane assembly, a first pipeline, and a second pipeline. The filtration device is used to remove insoluble particulate matter and macromolecules from the liquid medicine. The filter membrane assembly includes a filter membrane inlet, a filtrate outlet, and a macromolecule outlet. The inlet of the first pipeline is connected to the liquid medicine, and the outlet of the first pipeline is connected to the filter membrane inlet. The macromolecule outlet is connected to one end of the second pipeline, and the other end of the second pipeline is connected to the first pipeline. The buffer device includes a buffer tank, a third pipeline, and a fourth pipeline. The filtrate outlet is connected to one end of the third pipeline, and the other end of the third pipeline is connected to the inlet of the buffer tank. The outlet is connected to one end of the fourth pipeline, and the buffer tank is equipped with a magnetostrictive liquid level alarm. The concentration device includes a concentration membrane assembly, a fifth pipeline, and a sixth pipeline. The concentration device is used to remove excess water from the drug solution.

The first booster pump is installed on the first pipeline, and the second booster pump is installed on the fourth pipeline. The controller is communicatively connected to the filter device, the concentration device, the first booster pump, the second booster pump, and the magnetostrictive liquid level alarm.

[0006] Optionally, a seventh pipeline is also included, which is connected to the fourth pipeline, and a second pneumatic valve is provided on the seventh pipeline.

[0007] Optionally, a third pneumatic valve and a first pressure transmitter are provided at the inlet of the first pipeline, and the other end of the second pipeline is connected and installed between the first pressure transmitter and the first booster pump.

[0013] The continuous production apparatus for traditional Chinese medicine liquid preparations provided by this utility model includes a filtration device, a buffer device, a concentration device, a first booster pump, a second booster pump, and a controller. The liquid medicine enters the filter membrane tank assembly through a first pipeline. Large molecules that cannot pass through the filter membrane assembly enter the second pipeline through the large molecule outlet and then flow back into the first pipeline, where they re-enter the filter membrane assembly for filtration along with the remaining liquid medicine.

The buffer device 2 includes a buffer tank 10, a third pipeline 11, and a fourth pipeline 12. The filtrate outlet is connected to one end of the third pipeline 11, and the other end of the third pipeline 11 is connected to the inlet of the buffer tank 10. The outlet of the buffer tank 10 is connected to one end of the fourth pipeline 12. The buffer tank 10 is equipped with a magnetostrictive liquid level alarm 6.

[0020] It should be noted that when the device starts running, the first pneumatic valve 17 is opened, and when the volume of the small molecule liquid flowing out of the sixth pipeline 15 reaches the expected concentration ratio, the first pneumatic valve 17 is closed.

[0021] The continuous production apparatus for traditional Chinese medicine liquid preparations provided by this utility model includes a filtration device 1, a buffer device 2, a concentration device 3, a first booster pump 4, a second booster pump 5, and a controller. The medicinal liquid enters the filter membrane assembly 7 through the first pipeline 8. Large molecules that cannot pass through the filter membrane assembly 7 enter the second pipeline 9 through the large molecule outlet and then flow back into the first pipeline 8, where they re-enter the filter membrane assembly 7 together with the medicinal liquid that did not enter the filter membrane assembly 7 for circulating filtration. The filtrate that can pass through the filter membrane assembly 7 flows out from the filtrate outlet of the filter membrane assembly 7 and into the third pipeline 11. The filtrate then enters the buffer tank 10 in the apparatus through the third pipeline 11 and flows out from the buffer tank 10. The filtrate enters the concentration membrane assembly 13 through the fourth pipe 12 to remove excess water, thus concentrating the filtrate to form a concentrate. Small molecule liquids flow out from the drain outlet of the concentration membrane assembly 13, enter the sixth pipe 15, and then flow through the first pneumatic valve 17 before being discharged. The concentrate flows out from the concentrate outlet, enters the fifth pipe 14, merges back into the fourth pipe 12, and flows back into the concentration membrane assembly 13 for further concentration. The buffer device 2 stores the filtrate and adjusts the speed or start / stop of the first booster pump 4 and the second booster pump 5 according to the liquid level in the buffer tank 10 to ensure continuous and stable production. The liquid level in the buffer tank 10 is monitored by a magnetostrictive level alarm 6. This invention provides a continuous production device for traditional Chinese medicine liquid preparations, eliminating the impact of differences in filtration and concentration speeds between different types of medicinal liquids without altering the membrane components, ensuring a stable and continuous production process.

[0022] like Figure 1 As shown, it also includes a seventh pipeline 16, which is connected to the fourth pipeline 12. A second pneumatic valve 18 is installed on the seventh pipeline 16. In this embodiment, when the liquid from the sixth pipeline 15 reaches the required concentration, the first pneumatic valve 17 is closed, and the second pneumatic valve 18 is opened.

[0024] It improves the ease of use of continuous production equipment for traditional Chinese medicine liquid preparations.

[0025] like Figure 1 As shown, a second flow regulating valve 24 and a second check valve 25 are installed on the second pipeline 9. In this embodiment, the second flow regulating valve 24 can detect the flow rate of the liquid medicine in the second pipeline 9, and the second check valve 25 can prevent the liquid medicine from flowing back, thus improving the ease of use of the continuous production device for traditional Chinese medicine liquid preparations.

[0026] like Figure 1 As shown, a first manual ball valve 26 is installed on the third pipeline 11. In this embodiment, when the device is running, the first manual ball valve 26 is manually opened to allow the liquid medicine to smoothly enter the buffer tank 10. However, when the device stops working, the first manual ball valve 26 is manually closed, which improves the safety of the continuous production device for traditional Chinese medicine liquid preparations.

[0027] like Figure 1 As shown, the fourth pipeline 12 is also equipped with a fourth pneumatic valve 27, a third check valve 28, a third pressure transmitter 29, and a second manual ball valve 30. The second manual ball valve 30 is located at the outlet of the buffer tank 10. In this embodiment, when the device is running, the fourth pneumatic valve 27 is in the open state, allowing the liquid medicine to pass smoothly through the fourth pipeline 12. When the device stops working, the fourth pneumatic valve 27 is in the closed state, preventing the liquid medicine from entering the concentration membrane tank group through the fourth pipeline 12. The third check valve 28 can prevent the liquid medicine from flowing back. The third pressure transmitter 29 can detect the pressure of the liquid medicine in the fourth pipeline 12. The opening of the second manual ball valve 30 allows the liquid medicine in the buffer tank 10 to flow out smoothly.

[0030] The continuous production apparatus for traditional Chinese medicine liquid preparations provided by this utility model includes a filtration device 1, a buffer device 2, a concentration device 3, a first booster pump 4, a second booster pump 5, and a controller. The medicinal liquid enters the filter membrane assembly 7 through the first pipeline 8. Large molecules that cannot pass through the filter membrane assembly 7 enter the second pipeline 9 through the large molecule outlet and then flow back into the first pipeline 8, where they re-enter the filter membrane assembly 7 together with the medicinal liquid that did not enter the filter membrane assembly 7 for circulating filtration. The filtrate that can pass through the filter membrane assembly 7 flows out from the filtrate outlet of the filter membrane assembly 7 and into the third pipeline 11. The filtrate then enters the buffer tank 10 in the apparatus through the third pipeline 11 and flows out from the buffer tank 10. The filtrate enters the concentration membrane assembly 13 through the fourth pipe 12 to remove excess water, thus concentrating the filtrate to form a concentrate. Small molecule liquids flow out from the drain outlet of the concentration membrane assembly 13, enter the sixth pipe 15, and then flow through the first pneumatic valve 17 before being discharged. The concentrate flows out from the concentrate outlet, enters the fifth pipe 14, merges back into the fourth pipe 12, and flows back into the concentration membrane assembly 13 for further concentration. The buffer device 2 stores the filtrate and adjusts the speed or start / stop of the first booster pump 4 and the second booster pump 5 according to the liquid level in the buffer tank 10 to ensure continuous and stable production. The liquid level in the buffer tank 10 is monitored by a magnetostrictive level alarm 6.
