Description

Technical Field

[0001] The present invention relates to the technical field of graded alcohol precipitation equipment, and more particularly to a continuous graded alcohol precipitation device. Background Art

[0002] The water extraction and alcohol precipitation process has been widely used in traditional Chinese medicine preparations. Because ethanol is relatively cheap, non-toxic, and easy to operate, the alcohol precipitation process is currently the most commonly used impurity removal method in industrial production. The basic principle of alcohol precipitation, as described in Chinese patent document CN103070919A, is to utilize the property that some active ingredients of traditional Chinese medicine are soluble in both alcohol and water. A certain concentration of alcohol is used to precipitate some of the so-called insoluble components such as polysaccharides and proteins that are insoluble in ethanol, thereby achieving the purpose of refining the finished product and improving the quality of the finished preparation.

[0003] Most currently used alcohol precipitation equipment, such as those described in Chinese patents CN205340243U, CN205340241U, and CN205323297U, consists of a jacketed cylinder, an elliptical head, a conical-bottomed cylindrical body, and a rotating liquid outlet pipe. After alcohol precipitation, impurities settle at the bottom of the conical-bottomed cylindrical body, while the clear liquid is sucked out through the rotating liquid outlet pipe, and the precipitate is discharged through an outlet at the bottom of the tank.

[0004] Currently, the alcohol precipitation process commonly used in production involves first adding a traditional Chinese medicine aqueous extract to an alcohol precipitation device, adding ethanol while stirring, then allowing the solution to stand for a period of time, releasing the alcohol solution for centrifugation or filtration to remove the precipitate, and then cleaning the container before proceeding with the next batch of alcohol precipitation. Our research has found that while traditional alcohol precipitation equipment and processes achieve the goal of removing coarse ingredients while retaining essence, they also have a negative impact on the extraction yield of various active ingredients in traditional Chinese medicine. The main reason for this is that during alcohol precipitation, the aqueous and alcohol phases are mixed, and due to the large difference in solubility of ethanol-insoluble ineffective components in the two phases, the alcohol-insoluble components quickly precipitate in the aqueous phase and form agglomerates, which absorb and encapsulate some of the active ingredients. Furthermore, traditional alcohol precipitation equipment lacks sufficient stirring, which is a problem that urgently needs to be addressed in the existing technology. Summary of the Invention

For example, "connected" can mean a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, and it can be internal communication between two components. Those skilled in the art will be able to understand the specific meanings of the above terms in the present invention in specific circumstances. Example

[0037] See also Figure 1-9 A continuous graded alcohol precipitation device includes a reactor 10 and a stirring mechanism 1. The stirring mechanism 1 is arranged inside the reactor 10. The stirring mechanism 1 includes a frame 101 with a hollow structure. The stirring mechanism 1 can be used to realize a stirring reaction of the mixed liquid. For those skilled in the art, the stirring mechanism 1 is a prior art and will not be described in detail here. An elastic mechanism is provided on the outside of the stirring mechanism 1. The elastic mechanism has a certain elastic effect. During the stirring process, the elastic mechanism can scrape off the material on the inner wall of the reactor 10 to prevent residue and can fully stir. The reactor 10 is provided with an ethanol feed port 11 and a feeding port 12. A drug residue removal port 13 is provided at the bottom of the reactor 10. A driving mechanism 14 is provided at the upper end of the reactor 10.

[0038] The elastic mechanism includes an N-shaped fixed block 21 fixedly connected to the outside of the stirring mechanism 1, and the outside of the N-shaped fixed block 21 is slidably connected to the first slider 22 and the second slider 23. One side of the first slider 22 is fixedly connected to a first spring 29, and the first spring 29 is fixedly connected to the second slider 23. The N-shaped fixed block 21 can be used to place the first slider 22 and the second slider 23, so that the first slider 22 and the second slider 23 can slide smoothly. The first slider 22 and the second slider 23 can move in opposite directions and squeeze and contract the first spring 29, and the first spring 29 can bounce the first slider 22 and the second slider 23 back to their original position by its own elastic force to achieve the effect of buffering the first slider 22 and the second slider 23. One side of the first slider 22 and the second slider 23 is fixedly connected to a first fixed rod 24, and the outer side of the first fixed rod 24 is rotatably connected to a support rod 26. The first fixed rod 24 can be used to connect the support rod 26, so that the support rod 26 can squeeze and move the first slider 22 through the first fixed rod 24 when moving.

[0039] In addition, a connecting block 27 is provided on the outside of the stirring mechanism 1, and a second fixing rod 25 is fixedly connected to one side of the connecting block 27, and the support rod 26 is rotatably connected to the outside of the second fixing rod 25. The connecting block 27 can be used to connect the first baffle 28 and the second fixing rod 25, so that the first baffle 28 can drive the second fixing rod 25 to move through the connecting block 27 when moving, and the second fixing rod 25 can squeeze the support rod 26. At the same time, because the other side of the support rod 26 is rotatably connected to the first fixing rod 24, the first fixing rod 24 can limit the support rod 26. This makes it possible for the second fixing rod 25 to rotate smoothly when it moves to squeeze the support rod 26, and the support rod 26 can drive the first slider 22 to move through the first fixing rod 24 when rotating.

[0040] In addition, a first baffle 28 is fixedly connected to one side of the connecting block 27. The first baffle 28 is arc-shaped, and a scraper 19 is provided on the outer surface of the first baffle 28. The first baffle 28 can be used to connect the connecting block 27, so that the first baffle 28 can drive the connecting block 27 to move together when it moves, and the first baffle 28 has a larger area, which can better scrape the inner surface of the reactor 10. There are two first fixed rods 24, second fixed rods 25, support rods 26 and connecting block 27, so that the first baffle 28 can smoothly drive the two support rods 26 to rotate in the opposite direction when it moves, which enables the first slider 22 and the second slider 23 to move in opposite directions.

[0041] Specifically, a first hollow groove 41 is provided on one side of the first slider 22, and a second hollow groove 43 is provided on one side of the second slider 23. The first slider 22 can slide on the outside of the limit rod 42 through the first hollow groove 41, and the second slider 23 can slide on the outside of the limit rod 42 through the second hollow groove 43, so that the limit rod 42 is not easy to hinder the movement of the first slider 22 and the second slider 23. One side of the n-shaped fixed block 21 is fixedly connected to the limit rod 42, and the first slider 22 and the second slider 23 are both slidably connected to the outside of the limit rod 42, and the first spring 29 is sleeved on the outside of the limit rod 42. The limit rod 42 can limit the first spring 29, so that when the first slider 22 and the second slider 23 squeeze and contract the first spring 29, the first spring 29 is not easy to deform and bend, but can move and contract smoothly due to the limitation of the limit rod 42.

[0042] Specifically, a first limiting ring 31 and a second limiting ring 32 are provided on one side of the support rod 26. The first limiting ring 31 is fixedly connected to the first fixing rod 24. The first limiting ring 31 can limit the support rod 26 on the side of the first fixing rod 24, so that the support rod 26 is not easily separated from the first fixing rod 24. The second limiting ring 32 is fixedly connected to the second fixing rod 25. The function of the second limiting ring 32 is similar to that of the first limiting ring 31. It can limit the support rod 26 on the side of the second fixing rod 25, so that the support rod 26 can be more stable during rotation and is not easily separated from the second fixing rod 25.

[0043] Specifically, a telescopic rod 5 is provided on one side of the N-shaped fixed block 21, one end of the telescopic rod 5 is fixedly connected to the stirring mechanism 1, and the other end of the telescopic rod 5 is fixedly connected to the first baffle 28. The telescopic rod 5 can limit the first baffle 28, so that the first baffle 28 is not easily offset on the outside of the stirring mechanism 1, but can move smoothly. At the same time, the telescopic rod 5 consists of a first telescopic rod and a second telescopic rod, and the first telescopic rod is movably inserted into the inside of the second telescopic rod.

[0044] Specifically, a second spring 6 is fixedly connected to the outside of the stirring mechanism 1, and the second spring 6 is fixedly connected to the first baffle 28, and the support rod 26 is sleeved on the outside of the telescopic rod 5. The second spring 6 can assist the elastic mechanism to buffer the first baffle 28, so that the buffering effect of the first baffle 28 is better, and the effect is better when stirring and scraping the surface.

[0045] Specifically, a second baffle 7 is provided on one side of the first baffle 28, and the second baffle 7 is fixedly connected to the stirring mechanism 1. Through holes are evenly opened on the second baffle 7, which can increase the stirring area, improve the stirring effect, and achieve better mixing.

[0046] Specifically, the driving mechanism 14 includes a driving motor 1401 , and the lower output end of the driving motor 1401 is connected to the frame 101 via a coupling.

[0047] During use, the driving motor 1401 can drive the frame 101 to rotate, and the frame 101 can drive the elastic mechanism to rotate.

[0048] The reactor 10 is provided with a cover 15 , which has a first through hole 16 formed on the top of the reactor 10 . The cover 15 covers the first through hole 16 . A second through hole 17 is formed in the middle of the cover 15 . A reactor pressure control assembly 18 is installed between the reactor 10 and the cover 15 .

[0049] The reactor pressure control assembly 18 includes a tapered plug a1801 sealingly and slidably disposed inside the first through-hole 16, a tapered plug b1802 sealingly and slidably disposed on the second through-hole 17, a tapered plug b1802 sealingly and slidably disposed between the tapered plug a1801 and the second through-hole 17, a connecting rod 1803 disposed between the tapered plugs a1801 and b1802, a cover 15 fixedly disposed with a fixing sleeve 1804 on the outside of the connecting rod 1803, a memory alloy sheet 1805 fixedly disposed in the middle of the connecting rod 1803, the memory alloy sheet 1805 being a titanium-nickel memory alloy sheet, the nature of the memory alloy sheet 1805 being a two-way memory alloy, and the memory alloy sheet 1805 being sealed and fixedly connected to the fixing sleeve 1804;

[0050] The conical plug a1801 and the conical plug b1802 are both arranged in a conical shape, and the conical plug a1801 is arranged inside the reaction kettle 10, and the conical plug b1802 is arranged outside the cover 15.

[0051] The set conical plug a1801 is used to seal the first through hole 16, and the set conical plug b1802 is used to seal the second through hole 17. The set connecting rod 1803 is used to fix the conical plug a1801 and the conical plug b1802 to make the conical plug a1801 and the conical plug b1802 move synchronously. The set connecting rod 1803 fixes and supports the memory alloy sheet 1805. The memory alloy sheet 1805 is in a bent state under normal conditions, and the memory alloy sheet 1805 will return to a straight state and deform after being heated.

[0052] The fixed sleeve 1804 is fixedly supported by the set cover 15, and the memory alloy sheet 1805 is limited and fixed by the set fixed sleeve 1804. When the storage medium inside the reactor 10 and the cover 15 generates a large amount of gas due to the increase in temperature, and the pressure increases to be higher than the external atmospheric pressure, the memory alloy sheet 1805 will be deformed by the heat, which will drive the connecting rod 1803 to move, and the conical plug a1801 and the conical plug b1802 are driven to slide upward through the connecting rod 1803, so that the first through hole 16 and the second through hole 17 are opened, and the first through hole 16 and the second through hole 17 are automatically depressurized.

[0053] The working principle and use process of the present invention are as follows: When using the device, the first baffle 28 will drive the second fixed rod 25 to move together through the connecting block 27, and the second fixed rod 25 will drive the support rod 26 to rotate. At the same time, the support rod 26 will squeeze the first fixed rod 24 to move. Because there are two support rods 26 and two first fixed rods 24, the two support rods 26 can squeeze the first slider 22 and the second slider 23 through the first fixed rod 24 when moving, so that the first slider 22 and the second slider 23 can move in opposite directions. When the first slider 22 and the second slider 23 are in contact with each other, the first spring 29 will be squeezed by the first slider 29 to make the first spring 29 contract. Then the first spring 29 will rebound the first slider 22 and the second slider 23 to their original positions. At the same time, the first slider 22 will drive the support rod 26 to rotate in the opposite direction through the first fixing rod 24. At the same time, the support rod 26 will drive the first baffle 28 to move and reset through the second fixing rod 25 and the connecting block 27. A scraper 19 is connected to one side of the first baffle 28, which can better scrape the inner surface of the reactor 10 and improve the stirring effect.

[0054] The set conical plug a1801 is used to seal the first through hole 16, and the set conical plug b1802 is used to seal the second through hole 17. The set connecting rod 1803 is used to fix the conical plug a1801 and the conical plug b1802 to make the conical plug a1801 and the conical plug b1802 move synchronously. The set connecting rod 1803 fixes and supports the memory alloy sheet 1805. The memory alloy sheet 1805 is in a bent state under normal conditions, and the memory alloy sheet 1805 will return to a straight state and deform after being heated.

[0055] The fixed sleeve 1804 is fixedly supported by the set cover 15, and the memory alloy sheet 1805 is limited and fixed by the set fixed sleeve 1804. When the storage medium inside the reactor 10 and the cover 15 generates a large amount of gas due to the increase in temperature, and the pressure increases to be higher than the external atmospheric pressure, the memory alloy sheet 1805 will be deformed by the heat, which will drive the connecting rod 1803 to move, and the conical plug a1801 and the conical plug b1802 are driven to slide upward through the connecting rod 1803, so that the first through hole 16 and the second through hole 17 are opened, and the first through hole 16 and the second through hole 17 are automatically depressurized.

[0056] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes based on the technical solutions and improved concepts of the present invention within the technical scope disclosed by the present invention, and these changes should be covered by the scope of protection of the present invention.
