Description

Technical Field

[0001] This application relates to reaction vessels, and more particularly to a reaction vessel for producing pharmaceuticals. Background Technology

[0002] Drugs are substances used to prevent, treat, diagnose, and alleviate diseases. They act on the human body through chemical and biological means to improve health and reduce pain. A reaction vessel is a piece of equipment used in chemical reaction processes. It is widely used in industries such as chemical engineering, pharmaceuticals, and food processing. It is typically used to control and maintain specific temperatures, pressures, and reaction times to promote chemical reactions between raw materials. The basic functions of a reaction vessel are to contain reactants, mix them, heat and cool them, and simultaneously discharge reaction products.

[0003] A search revealed Chinese Patent Publication No. CN212663537U, which discloses a reaction vessel for drug manufacturing, belonging to the field of reaction vessel technology. The vessel includes a vessel body, with an inlet and a fixed base fixedly connected to the upper surface of the vessel body, and an outlet fixedly connected to the lower surface of the vessel body. A motor is fixedly connected to the upper surface of the fixed base. An insulation layer is tightly fitted to the bottom of the vessel body's interior, and a heating wire pipe is tightly fitted to one side of the insulation layer, with a heating wire embedded inside the heating wire pipe. In this invention, the raw materials required for drug manufacturing are added through the inlet. However, some drug manufacturing requires a specific temperature. The heating wire can then be switched on via a control panel. The heating wire generates heat, which is transferred sequentially through the heating wire pipe and the heat conduction layer to the raw materials. This solves the problem that existing drug manufacturing reaction vessels do not provide sufficient heating for drug raw materials, necessitating improvements to existing drug manufacturing reaction vessels.

[0004] While the aforementioned patents address the insufficient heating effect of existing pharmaceutical manufacturing reactors on drug raw materials, they cannot effectively prevent the detachment and aging of sealing materials due to long-term friction and repeated use. This not only increases maintenance costs but also adversely affects drug purity and production efficiency. Therefore, a new reactor for drug production is proposed to solve these problems. Utility Model Content

[0032] The following is in conjunction with the appendix Figure 1 -Appendix Figure 5 This application will be described in further detail below.

[0033] Example: A reaction vessel for producing pharmaceuticals, referenced Figure 2 , Figure 3 and Figure 5 The reaction vessel includes a cylindrical reactor body 1 with a smooth inner wall, exhibiting good corrosion resistance and durability. A reactor cover 2, circular in shape, is fixedly connected to the top of the reactor body 1 to seal the reactor body 1 and prevent material leakage during the reaction. An anti-detachment mechanism 3 is fixedly connected to the top of the reactor cover 2. The anti-detachment mechanism 3 includes an inlet 31, cylindrical in shape with multiple threaded grooves on its exterior for connecting to a sealing cover 36. Both the inlet 31 and the sealing cover 36 have multiple threaded grooves on their exterior and interior, respectively. These grooves engage to ensure a tight fit between the inlet 31 and the sealing cover 36. 1 is externally fixedly connected to the top of the reactor cover 2. Multiple lower L-shaped blocks 32 are fixedly connected to the top of the injection port 31. The lower L-shaped blocks 32 are made of flexible material and are used to support and fix the sealing ring 34. Multiple upper L-shaped blocks 33 are slidably connected to the top of the injection port 31. The upper L-shaped blocks 33 are made of flexible material and support and fix the sealing ring 34 in cooperation with the lower L-shaped blocks 32. The sealing ring 34 is fixedly connected to the adjacent side of the upper L-shaped blocks 33 and the lower L-shaped blocks 32. The sealing ring 34 is circular and is used to prevent material leakage. The outside of the sealing ring 34 is slidably connected to the inside of the sealing ring 37. The inside of the sealing ring 37 is slidably connected to the outside of the upper L-shaped blocks 33.

[0034] Specifically, the reactor body is cylindrical with a smooth inner wall, possessing excellent corrosion resistance and durability, adapting to the complex chemical environment of drug production, and extending the service life of the equipment. Secondly, the anti-detachment mechanism 3 on the top of the reactor cover 2 is ingeniously designed. The injection port 31 and the sealing cover 36 are tightly fitted through threaded grooves to ensure a firm connection and effectively prevent material leakage. The upper and lower L-shaped blocks 32 made of flexible material cooperate to support and fix the sealing ring 34. The sliding connection between the sealing ring 34 and the sealing ring 37 further enhances the sealing performance, providing a reliable sealing guarantee for the drug production process and ensuring safe and efficient production.

[0035] A barrier component 35 is slidably connected inside the inlet 31. The barrier component 35 includes a filter box 351, which is cylindrical in shape. The filter box 351 is slidably connected to the inside of the inlet 31. Limiting blocks 352 are fixedly connected to the left and right sides of the filter box 351. The limiting blocks 352 are rectangular in shape and are used to limit the movement range of the filter box 351 to ensure its stability and reliability. The two limiting blocks 352 are slidably connected to the inside of the inlet 31 and to the inside of the sealing ring 34. The internal fixed connection of 51 is a connecting post 353, which is cylindrical in shape and is used to connect and fix the filter box 351, so that the filter box 351 can be removed from the inside of the inlet 31 by applying force. The external thread of the inlet 31 is connected to a sealing cover 36, which is cylindrical in shape and has multiple threaded grooves inside, which cooperate with the threaded grooves of the inlet 31 to make the inlet 31 and the sealing cover 36 fit tightly to ensure the sealing performance. The internal fixed connection of the sealing cover 36 is a sealing ring 37, which is circular in shape to further enhance the sealing effect.

[0036] Specifically, the filter box 351 inside the injection port 31 is cylindrical, and the limiting block 352 on its outside can limit the range of movement, enhance stability and reliability. The limiting block 352 is slidably connected to the sealing ring 34 inside, further ensuring the sealing performance. The connecting post 353 inside the filter box 351 makes it easy to remove the filter box 351 from the injection port 31 for cleaning and replacement. The sealing cover 36 on the outside of the injection port 31 is tightly fitted with the injection port 31 by threads, and the sealing ring 37 inside it further enhances the sealing effect, effectively preventing material leakage, ensuring the sealing and safety of the reactor in the drug production process, and improving production efficiency and product quality.

[0037] Reference Figure 1 , Figure 2 and Figure 4A heating mechanism 4 is fixedly connected inside the reactor body 1. The heating mechanism 4 includes multiple heating tubes 41, which are cylindrical in shape and used to heat the materials inside the reactor. The multiple heating tubes 41 are fixedly connected to the outside of the reactor body 1. A motor 42 is fixedly connected to the top of the reactor cover 2. A rotating shaft 43 is fixedly connected to the drive end of the motor 42. Multiple stirring plates 44 are fixedly connected to the outside of the rotating shaft 43. The stirring plates 44 are used to stir the materials to ensure uniform reaction. A connecting plate 45 is fixedly connected to the outside of the rotating shaft 43 to transmit the force of rotation of the rotating shaft 43. Cleaning plates 46 are fixedly connected to both sides of the connecting plate 45. The cleaning plates 46 are rectangular in shape and used to clean the heating tubes 41 to prevent scaling. The reactor body 1 is slidably connected to the outside of the two cleaning plates 46. The outside of the two cleaning plates 46 is fixedly connected to the outside of the multiple heating tubes 41.

[0038] Specifically, multiple heating tubes 41 inside the reactor can efficiently heat the materials to ensure the required reaction temperature. The motor 42 drives the rotating shaft 43 and the stirring plate to rotate, so that the materials are fully stirred and the reaction is uniform. At the same time, the connecting plate 45 on the rotating shaft 43 drives the cleaning plate 46 to rotate. The cleaning plate 46 is in close contact with the outside of the heating tubes 41, which can effectively clean the heating tubes 41, prevent scaling, improve heating efficiency, extend the service life of the heating tubes 41, ensure the stable operation of the reactor and the reaction effect, and improve the quality and efficiency of drug production.

[0039] An external heating assembly 47 is fixedly connected to the outside of the reactor body 1. The external heating assembly 47 includes a jacket 471, which is cylindrical in shape and is used to provide external heating. The inside of the jacket 471 is fixedly connected to the outside of the reactor body 1. Connection ports 472 are fixedly connected to the bottom left and right sides of the jacket 471. The connection ports 472 are circular tubular in shape and made of stainless steel, and are used to connect to an external heat source to provide a heating medium.

[0040] Specifically, the jacket 471 is cylindrical and tightly fixed to the outside of the reactor body, providing stable external heating to ensure that the materials inside the reactor react in a uniform temperature field. The two connection ports 472 at the bottom of the jacket 471 are made of stainless steel, which has good corrosion resistance and durability. They are used to connect external heat sources and introduce heating media, such as hot water or steam, to effectively heat the reactor. This not only improves heating efficiency but also allows for flexible adjustment of the heating temperature according to reaction requirements, ensuring the smooth progress of the reaction. It also helps to improve the energy utilization efficiency of the reactor, reduce production costs, and ensure the quality and efficiency of drug production.

[0041] The implementation principle of this application embodiment is as follows: First, the sealing cap 36 needs to be unscrewed from the injection port 31. Then, the upper L-shaped block 33 is pushed upward and the lower L-shaped block 32 is pushed downward to install the sealing ring 34 on the top of the injection port 31. Then, the upper L-shaped block 33 and the lower L-shaped block 32 are released. The upper L-shaped block 33 and the lower L-shaped block 32 return to their original positions due to their flexibility, thereby forming a fixed limit on the sealing ring 34. Next, the filter screen box 351 is inserted along the inner wall of the injection port 31 until the limiting block 352 reaches the corresponding position inside the injection port 31. Then, the sealing cap 36 is tightened on the injection port 31. At this time, the sealing ring 37 will be tightly attached to the outside of the sealing ring 34, further enhancing the sealing effect. The material enters the reactor body 1 through the injection port 31. During the entry process, the filter screen box 351 will filter the material to prevent impurities from mixing in. If the filter screen box 351 needs to be cleaned, the sealing cap 36 can be unscrewed and the filter screen box 351 can be pulled out upward.

[0042] Subsequently, after the motor 42 starts, the rotating shaft 43 begins to rotate, driving the stirring plate 44 to stir the material, so that the reaction inside 1 can proceed evenly. At the same time, the heating tube 41 directly heats the material, and the jacket 471 in the external heating component 47 is connected to an external heat source through the connection port 472 to provide external heating for the reactor body 1. Through the combination of internal and external heating, different reaction temperature requirements are met. During the reaction, the connecting plate 45 transmits the rotation of the rotating shaft 43 to the cleaning plate 46, so that the cleaning plate 46 slides along the surface of the heating tube 41 and uses the grooves on its surface to rub and clean the heating tube 41, preventing liquid residue from remaining in the gap between the heating tube 41 and the reactor body 1 and causing corrosion to the heating tube 41.

[0043] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
