Abstract
Description
Technical Field
[0001] The present disclosure relates to the technical field of pharmaceutical raw material production. Specifically, it relates to a distillation tank and a distillation method for the production of pharmaceutical raw materials. Background Art
[0002] In the production process of pharmaceutical raw materials, distillation is a crucial means of separation and purification. Existing distillation tanks for the production of pharmaceutical raw materials usually consist of a tank body, a heating device, a condensation device, and related pipelines and control systems.
[0003] Among them, the tank body, as the main accommodating component, is used to hold the material to be distilled. The heating device is generally arranged at the bottom of the tank body. Common heating methods include heating with electric heating wires or indirectly heating through a heat medium (such as heat-conducting oil). Its function is to provide the heat required for the evaporation of the material and promote the gasification of low-boiling components. Most of the distillation tank bodies in the prior art are cylindrical. The material evaporates during the process of flowing from one side of the distillation tank body to the other side. However, during the actual distillation operation, most of the materials in the distillation tank body cannot fully contact the heating surface during the evaporation and flow process, resulting in an extended evaporation time for some materials, making it difficult to improve the overall production efficiency. Moreover, in the existing heating methods, most of them heat the bottom of the distillation tank body. The materials near the bottom of the distillation tank body are heated more, while the materials in the upper part are heated relatively insufficiently. This temperature difference easily causes local overheating and decomposition of the materials, not only affecting the quality of the raw materials but also reducing the product yield. Summary of the Invention

The distillation cylinder is arranged through between the large-mouth positioning plate and the small-mouth positioning plate. A conical heating area is formed between the conical heating box and the distillation cylinder. A spiral guide blade capable of heating the gas to move spirally from the large-mouth positioning plate towards the small-mouth positioning plate is provided inside the conical heating area; The steam compressor is installed on the distillation rack. Between the exhaust end of the steam compressor and the large-mouth positioning plate, there is a hot gas delivery pipe group capable of delivering hot gas to the conical heating area, and the intake end of the steam compressor is connected to an intake pipe group; The exhaust pipe group is connected and arranged between the small-mouth positioning plate and the intake pipe group; The steam delivery pipe group is connected and arranged between the distillation cylinder and the intake pipe group.
[0006] On the basis of the foregoing solution, the spiral feeding blade is arranged on the feeding power assembly, and the feeding power assembly is installed between the distillation rack and the distillation cylinder; The feeding power assembly includes a power shaft and a power motor; The power shaft penetrates and is rotatably arranged in the distillation cylinder in a sealed manner, and the spiral feeding blade is arranged on the power shaft; The power motor is installed on one side of the distillation rack, and the output end of the power motor is connected to one end of the power shaft.
[0007] On the basis of the foregoing solution, the hot gas delivery pipe group includes a first ring pipe and a first delivery pipe; The first ring pipe is connected to the conical heating area through a plurality of first short pipes distributed at equal angles, and the first short pipes penetrate through the large-mouth positioning plate; The first delivery pipe is connected and arranged between the first ring pipe and the exhaust end of the steam compressor.
[0008] On the basis of the foregoing solution, the intake pipe group includes an intake main cylinder and an intake main pipe; The intake main cylinder is arranged on one side of the distillation rack; The intake main pipe is connected and arranged between the intake main cylinder and the intake end of the steam compressor.
[0009] On the basis of the foregoing solution, the exhaust pipe group includes a second ring pipe, a second delivery pipe, and a second exhaust pipe; The second ring pipe is connected to the conical heating area through a plurality of second short pipes distributed at equal angles, and the second short pipes penetrate through the small-mouth positioning plate; The second delivery pipe is connected and arranged between the second ring pipe and the intake main cylinder, and a delivery regulating valve is installed on the second delivery pipe; There are several second exhaust pipes, and one end of each second exhaust pipe is connected and arranged on the second delivery pipe for discharging the gas in the second delivery pipe to the air.
[0010] On the basis of the foregoing solution, the steam delivery pipe group includes a steam main pipe and a steam branch pipe; The steam main pipe is connected to the top of the distillation cylinder through a plurality of steam short pipes; There are two steam inlet pipes, which are connected between the steam main pipe and the main intake cylinder and are used for the secondary circulation of the evaporation gas.
[0011] On the basis of the above solution, a feed pipe extending upward is connected to one side of the distillation cylinder close to the large-mouth positioning plate.
[0012] On the basis of the above solution, a discharge pipe extending downward is connected to one side of the distillation cylinder close to the small-mouth positioning plate, and a discharge valve is installed on the discharge pipe.
[0013] Further on the basis of the above solution, a pressure detection sensor capable of performing air pressure detection is installed on the main intake cylinder.
[0014] A distillation method for a distillation tank used in the production of pharmaceutical raw materials uses the above-mentioned distillation tank for the production of pharmaceutical raw materials, and includes the following steps: Step 1, material transportation: The material to be distilled is transported into the distillation cylinder through the feed pipe. By starting the power motor, the spiral feeding blade rotates, and the rotation of the spiral feeding blade drives the material in the distillation cylinder to move spirally along the inner wall of the distillation cylinder towards the side of the discharge pipe; Step 2, heating and distillation: Start the steam compressor to transport hot air to the conical heating area. The hot air spirally moves under the action of the spiral guide blade to heat the distillation cylinder, so that the material evaporates in the distillation cylinder. The steam generated by the material will enter the steam compressor through the steam delivery pipe group and the intake pipe group for secondary heating circulation; Step 3, material discharge: After distillation is completed, open the valve of the discharge pipe, and the distilled material will be discharged through the discharge pipe.
[0015] The beneficial effects of the present disclosure are as follows: 1. In the present disclosure, by arranging the spiral feeding blade inside the distillation cylinder, under the rotation of the spiral feeding blade, the material can be driven to move spirally along the inner wall of the distillation cylinder. This unique movement method greatly increases the residence time of the material in the distillation cylinder, enables the material to fully contact the distillation cylinder wall, and then fully absorb heat, improving the distillation efficiency. Compared with the traditional simple stirring type feeding, the design of the spiral feeding blade makes the material heat more evenly, avoiding local overheating or insufficient heating, ensuring the stability and high efficiency of the distillation process. And the rotation of the spiral feeding blade makes the material show a spiral upward or downward movement trajectory in the distillation cylinder, making the material more evenly distributed in the distillation cylinder, and there will be no phenomenon of material accumulation in a certain place. This helps to improve the consistency of the distillation effect of the material in the entire distillation cylinder and reduce the distillation quality difference caused by uneven material distribution; 2. In the present disclosure, a conical heating zone is formed between the conical heating box and the distillation cylinder, and spiral guide vanes are provided in the conical heating zone. After the steam compressor transports the hot gas to the conical heating zone, the hot gas spirally moves along the large-mouth positioning plate towards the small-mouth positioning plate under the action of the spiral guide vanes. This spirally moving hot gas can not only more fully surround the distillation cylinder, increasing the contact area and contact time between the hot gas and the distillation cylinder, but also when the gas enters from the side with a larger diameter, as the gas flows towards the side with a smaller diameter, the gas will be compressed, increasing its internal energy and temperature. At the same time, the gas flow rate gradually increases, the convective heat transfer coefficient increases, and the heat exchange between the gas and the pipe wall becomes more intense, causing the temperature of the pipe to gradually increase along the gas flow direction, showing an increasing form. This increasing temperature, after being transferred into the distillation cylinder, can more conveniently heat and evaporate the material as the moisture inside the material decreases and the boiling point increases as the material flows towards the discharge pipe side, without affecting the evaporation efficiency of the material, making the distillation process more efficient; 3. In the present disclosure, by setting up a steam compressor, a hot gas delivery pipe group, an intake pipe group, an exhaust pipe group, and a steam delivery pipe group, the steam evaporated in the distillation cylinder and part of the gas in the conical heating zone will enter the steam compressor for secondary circulation heating, and then be transported back to the conical heating zone through the hot gas delivery pipe group to heat the distillation cylinder. This not only realizes the recycling of hot gas, greatly improves the energy utilization rate, reduces energy consumption, but also avoids the accumulation of steam in the distillation cylinder affecting the distillation effect.

[0019] The present disclosure will be further described in detail below with reference to the accompanying drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the present disclosure, rather than limiting the present disclosure.

[0024] In addition, in the description of this application, the terms "first", "second", etc. are only used for distinguishing descriptions, and cannot be construed as indicating or implying relative importance.
[0025] Example 1, as Figures 1 to 7 shown, a distillation tank for the production of pharmaceutical raw materials includes a distillation rack 1, a distillation cylinder 2, a conical heating tank 4, a steam compressor 8, an exhaust pipe group 003 and a steam delivery pipe group 004.
[0026] As described above, the distillation cylinder 2 is arranged on the distillation rack 1, and a spiral feeding blade 3 capable of driving the material to move spirally along the inner wall of the distillation cylinder 2 is arranged inside the distillation cylinder 2.
[0027] Among them, the spiral feeding blade 3 is arranged on the feeding power assembly, the feeding power assembly is installed between the distillation rack 1 and the distillation cylinder 2, the feeding power assembly includes a power shaft 9 and a power motor 10, the power shaft 9 penetrates and is rotatably arranged in the distillation cylinder 2 in a sealed manner, the spiral feeding blade 3 is arranged on the power shaft 9, the power motor 10 is installed on one side of the distillation rack 1, and the output end of the power motor 10 is connected to one end of the power shaft 9.
[0028] Specifically, start the power motor 10. The output end of the power motor 10 can drive the power shaft 9 to rotate. Through the rotation of the power shaft 9, the spiral feeding blade 3 can be driven to rotate. Under the rotation of the spiral feeding blade 3, the material can be driven to move spirally along the inner wall of the distillation cylinder 2. This unique movement method greatly increases the residence time of the material in the distillation cylinder 2, enables the material to fully contact the wall of the distillation cylinder 2, and thus fully absorbs heat, improving the distillation efficiency. Compared with the traditional simple stirring type feeding, the design of the spiral feeding blade 3 makes the material heated more evenly, avoiding the situation of local overheating or insufficient heating, ensuring the stability and efficiency of the distillation process. Moreover, the rotation of the spiral feeding blade 3 makes the material present a spiral rising or falling movement trajectory in the distillation cylinder 2, making the material more evenly distributed in the distillation cylinder 2 and preventing the phenomenon of material accumulation at a certain place. This helps to improve the consistency of the distillation effect of the material in the entire distillation cylinder 2 and reduce the distillation quality difference caused by uneven material distribution.
[0029] As described above, the conical heating box 4 is arranged on the distillation rack 1. A large-mouth positioning plate 5 is arranged on the side with a larger diameter of the conical heating box 4, and a small-mouth positioning plate 6 is arranged on the side with a smaller diameter. The distillation cylinder 2 is arranged through between the large-mouth positioning plate 5 and the small-mouth positioning plate 6. A conical heating area is formed between the conical heating box 4 and the distillation cylinder 2. A spiral guide vane 7 is arranged in the conical heating area, which can make the heated gas move spirally along the large-mouth positioning plate 5 towards the small-mouth positioning plate 6.
[0030] Specifically, a conical heating area is formed between the conical heating box 4 and the distillation cylinder 2, and a spiral guide vane 7 is arranged in the conical heating area. After the steam compressor 8 transports the hot gas to the conical heating area, the hot gas moves spirally along the large-mouth positioning plate 5 towards the small-mouth positioning plate 6 under the action of the spiral guide vane 7. This spirally moving hot gas can not only more fully surround the distillation cylinder 2, increasing the contact area and contact time between the hot gas and the distillation cylinder 2, but also when the gas is introduced from the side with a larger diameter, as the gas flows towards the side with a smaller diameter, the gas will be compressed, increasing its internal energy and temperature. At the same time, the gas flow rate gradually increases, the convective heat transfer coefficient increases, and the heat exchange between the gas and the pipe wall becomes more intense, causing the temperature of the pipe to gradually increase along the gas flow direction, showing an increasing form. After this increasing temperature is transferred into the distillation cylinder 2, as the water content in the material decreases and the boiling point increases as the material flows towards the discharge pipe 25 side, it is more convenient to heat and evaporate the material without affecting the evaporation efficiency of the material, making the distillation process more efficient.
[0031] It should be noted that when the gas is introduced from the side with a larger diameter, as the gas flows towards the side with a smaller diameter, the distillation cylinder 2 can exhibit an increasing temperature. If the gas is introduced from the side with a smaller diameter, although the gas velocity is fast and the convective heat transfer is strong at the small-diameter part, the gas expands when flowing towards the side with a larger diameter, and generally the temperature will decrease, making it difficult to achieve the effect of increasing the temperature inside the pipeline.
[0032] As Figure 1 and Figure 5 shown, for the above-mentioned, the steam compressor 8 is installed on the distillation rack 1. Between the exhaust end of the steam compressor 8 and the large-mouth positioning plate 5, there is a hot gas delivery pipe group 001 capable of delivering hot gas to the conical heating area. The intake end of the steam compressor 8 is connected to an intake pipe group 002. The exhaust pipe group 003 is connected and arranged between the small-mouth positioning plate 6 and the intake pipe group 002. The steam delivery pipe group 004 is connected and arranged between the distillation cylinder 2 and the intake pipe group 002.
[0033] Among them, the hot gas delivery pipe group 001 includes a first annular pipe 11 and a first delivery pipe 13. The first annular pipe 11 is connected to the conical heating area through a number of equally angularly distributed first short pipes 12. The first short pipes 12 are arranged through the large-mouth positioning plate 5. The first delivery pipe 13 is connected and arranged between the first annular pipe 11 and the exhaust end of the steam compressor 8.
[0034] Among them, the intake pipe group 002 includes an intake main cylinder 14 and an intake main pipe 15. The intake main cylinder 14 is arranged on one side of the distillation rack 1. The intake main pipe 15 is connected and arranged between the intake main cylinder 14 and the intake end of the steam compressor 8.
[0035] Among them, the exhaust pipe group 003 includes a second annular pipe 16, a second delivery pipe 18, and a second exhaust pipe 20. The second annular pipe 16 is connected to the conical heating area through a number of equally angularly distributed second short pipes 17. The second short pipes 17 are arranged through the small-mouth positioning plate 6. The second delivery pipe 18 is connected and arranged between the second annular pipe 16 and the intake main cylinder 14. A delivery regulating valve 19 is installed on the second delivery pipe 18. There are a number of second exhaust pipes 20. One end of the second exhaust pipe 20 is connected and arranged on the second delivery pipe 18 for discharging the gas in the second delivery pipe 18 to the air.
[0036] Among them, the steam delivery pipe group 004 includes a steam main pipe 21 and a steam branch pipe 23. The steam main pipe 21 is connected to the top of the distillation cylinder 2 through a number of steam short pipes 22. There are two steam branch pipes 23. The steam branch pipes 23 are connected and arranged between the steam main pipe 21 and the intake main cylinder 14 for the secondary circulation of the evaporated gas.
[0037] Specifically, when heating and evaporating the material in the distillation cylinder 2, the steam compressor 8 is started. The steam compressor 8 heats the inhaled gas, and through the exhaust end of the steam compressor 8, the heated gas is evenly transported into the conical heating area from multiple first short pipes 12 along the first delivery pipe 13 and the first annular pipe 11, so that the heated gas flows in the conical heating area to heat the distillation cylinder 2, thereby heating and evaporating the material in the distillation cylinder 2. The high-temperature steam generated during the evaporation of the material is sucked by the intake end of the steam compressor 8, and the high-temperature steam will enter the steam compressor 8 through the steam short pipe 22, the steam main pipe 21, the steam branch pipe 23, the intake main cylinder 14 and the intake main pipe 15 for cyclic heating use.
[0038] During the process of distilling the material, since the steam compressed and heated by the steam compressor 8 cannot fully utilize the steam generated in the distillation cylinder 2, if the gas in the distillation cylinder 2 is completely used, the gas flow rate in the distillation cylinder 2 will be too fast, resulting in slow heating of the material and reduced evaporation efficiency of the material. Therefore, the gas entering the steam compressor 8 also needs to be compensated by part of the gas in the conical heating area. After cycling, the hot gas in the conical heating area enters the second annular pipe 16 through the second short pipe 17. By opening the delivery regulating valve 19, part of the gas will enter the intake main cylinder 14 through the second delivery pipe 18, and part of the gas will be discharged through the second exhaust pipe 20. An air pressure detection sensor 27 capable of detecting air pressure is installed on the intake main cylinder 14, which can monitor the air pressure in the intake main cylinder 14 in real time. By monitoring the air pressure, the state of the gas entering the steam crusher can be understood in time, and by adjusting the size of the delivery regulating valve 19, the ratio of the steam in the distillation cylinder 2 and the hot gas in the conical heating area entering the intake main cylinder 14 can be adjusted to ensure the safety and stability of the distillation process.
[0039] Furthermore, there will be a large amount of moisture in the hot gas discharged through the second exhaust pipe 20. One side of the second exhaust pipe 20 needs to be connected to a condensing device to separate the moisture in the gas until the discharge requirements are met before discharging to the air.
[0040] Furthermore, a feed pipe 24 extending upward is connected to one side of the distillation cylinder 2 close to the large-mouth positioning plate 5, and a discharge pipe 25 extending downward is connected to one side of the distillation cylinder 2 close to the small-mouth positioning plate 6. A discharge valve 26 is installed on the discharge pipe 25. The feed pipe 24 is used for putting the material to be evaporated, and the discharge pipe 25 is used for discharging the evaporated material. By setting the discharge valve 26 on the discharge pipe 25, when cleaning the inside of the distillation cylinder 2, after injecting cleaning water through the discharge pipe 25 and closing the discharge valve 26, the cleaning water can be stored in the distillation cylinder 2, and by rotating the spiral feeding blade 3, the inside of the distillation cylinder 2 can be cleaned.
[0041] Embodiment 2: Embodiment 2 of the present disclosure proposes a distillation method for a distillation tank for the production of pharmaceutical raw materials based on Embodiment 1. The specific method is as follows: Material transportation, the material to be distilled is transported to the distillation cylinder 2 through the feed pipe 24, and the spiral feed blade 3 is rotated by starting the power motor 10. The rotation of the spiral feed blade 3 drives the material in the distillation cylinder 2 to perform a spiral motion along the inner wall of the distillation cylinder 2 toward one side of the discharge pipe 25.
[0042] Heating distillation, start the steam compressor 8 to transport hot air to the conical heating area. The hot air moves in a spiral motion under the action of the spiral guide vanes 7 to heat the distillation cylinder 2, so that the material evaporates in the distillation cylinder 2. The steam generated by the material will enter the steam compressor 8 through the steam conveying pipe group 004 and the air inlet pipe group 002 for secondary heating cycle.
[0043] Material discharge, distillation is completed, open the discharge pipe 25 valve, and the distilled material will be discharged through the discharge pipe 25.
[0044] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present disclosure rather than to limit it. Although the present disclosure has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present disclosure may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present disclosure, which should be included in the scope of the claims of the present disclosure.

A distillation method for a distillation tank used in the production of a pharmaceutical raw material drug, which uses a distillation tank for the production of a pharmaceutical raw material drug described in any one of claims 1 to 9, and is characterized in that, It includes the following steps: S1. Material transportation: The material to be distilled is transported into the distillation cylinder (2) through the feed pipe (24). By starting the power motor (10), the spiral feeding blade (3) rotates, and the rotation of the spiral feeding blade (3) drives the material in the distillation cylinder (2) to move spirally along the inner wall of the distillation cylinder (2) towards the side of the discharge pipe (25). S2. Heating and distillation: Start the steam compressor (8) to deliver hot gas to the conical heating area. The hot gas spirally moves under the action of the spiral guide blade (7) to heat the distillation cylinder (2), so that the material evaporates in the distillation cylinder (2). The steam generated by the material will enter the steam compressor (8) through the steam delivery pipe group (004) and the intake pipe group (002) for secondary heating circulation. S3. Material discharge: After distillation, open the valve of the discharge pipe (25), and the distilled material will be discharged through the discharge pipe (25).
