Description

Technical Field

[0001] This utility model relates to the field of reaction vessel technology, and in particular to a high-sealing reaction vessel. Background Technology

[0002] A reaction vessel is a sealed, pressure-resistant container used to perform physical or chemical reactions, widely used in chemical, pharmaceutical, and petroleum industries. Its basic structure includes the vessel body, stirring device, heat transfer jacket, and sealing structure. By controlling key parameters such as temperature, pressure, stirring speed, and material dosage ratios, the reaction vessel provides a safe and controllable ideal environment for various chemical reactions such as synthesis, hydrolysis, and polymerization. Modern reaction vessels are often equipped with automated control systems, enabling precise process management and data recording, significantly improving production efficiency and product quality stability, making them core equipment in modern batch chemical production.

[0003] To ensure timely delivery of reactants to the reactor, appropriate material conveying pipes need to be installed on the reactor. This necessitates the creation of mounting holes in the reactor to accommodate the conveying pipes. This results in a gap at the connection between the conveying pipes and the reactor. To prevent spillage of reactants, flanges are typically used for assembly and sealing between the conveying pipes and the reactor. While flanges effectively connect and seal, their sealing performance is relatively poor and cannot meet high-level sealing requirements. Utility Model Content

[0017] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0018] A high-sealing reactor includes: a reactor body 1, a conveying pipe 2, and a sealing device 3. The reactor body 1 has an opening corresponding to the conveying pipe 2. The conveying pipe 2 extends into the reactor body 1 through the opening. The sealing device 3 includes a pre-connecting ring 31 and a connecting flange 32. The pre-connecting ring 31 is rotatably connected to the conveying pipe 2. The pre-connecting ring 31 has threads. The pre-connecting ring 31 is connected to the reactor body 1 via the threads. The connecting flange 32 is fitted onto the conveying pipe 2. The connecting flange 32 is connected to the reactor body 1. When the connecting flange 32 is connected to the reactor body 1, the connecting flange 32 engages with the pre-connecting ring 31.

[0019] In practice, the vessel body 1 has a pre-drilled threaded groove for connecting the pre-connecting ring 31. The operator aligns the conveying pipe 2 with the opening on the vessel body 1 and pushes the pipe 2 into the vessel body 1. At this point, the pre-connecting ring 31 aligns with the threaded groove on the vessel body 1. The operator rotates the pre-connecting ring 31, gradually and stably connecting it to the vessel body 1. After the pre-connecting ring 31 is connected, the connecting flange 32 is pushed and fixedly connected to the pre-drilled connection port on the vessel body 1. The connecting flange 32 is then engaged with the pre-connecting ring 31. Thus, through the dual connection method of the connecting flange 32 and the pre-connecting ring 31, the leakage path of the reactants inside the vessel body 1 becomes more complex, thereby enhancing the overall sealing performance.

[0020] A connecting rail 311 is provided on the pre-connecting ring 31. The connecting rail 311 is a closed ring. The cross-section of the connecting rail 311 is T-shaped. One side of the connecting rail 311 is fixedly connected to the inner wall of the pre-connecting ring 31. The other side of the connecting rail 311 extends into the side wall of the conveying pipe 2.

[0021] Thus, the pre-connecting ring 31 is connected to the conveying pipe 2 via the connecting rail 311, and can rotate relative to the conveying pipe 2 via the connecting rail 311.

[0022] A pressing device 312 is also provided on the pre-connecting ring 31. The pressing device 312 is connected to the connecting rail 311. The pressing device 312 includes a sealing ring 3121 and a pressing spring 3122. The sealing ring 3121 protrudes from the outer edge of the connecting rail 311. A groove corresponding to the sealing ring 3121 is formed in the side wall of the conveying pipe 2. The pressing spring 3122 is disposed in the connecting rail 311. The pressing spring 3122 abuts against the sealing ring 3121. Specifically, the pressing device 312 also includes a support rod 3123. The support rod 3123 is arranged vertically. The support rod 3123 is slidably disposed in the connecting rail 311. The support rod 3123 is connected to the sealing ring 3121. The support rod 3123 abuts against the pressing spring 3122. On the other hand, the pressing device 312 also includes a positioning plate 3124 and a positioning pin 3125. The positioning plate 3124 is fixedly connected to the bearing rod 3123. The positioning pin 3125 passes through the pre-connecting ring 31. One end of the positioning pin 3125 abuts against the positioning plate 3124.

[0023] In the default state, the positioning pin 3125 abuts against the positioning plate 3124, causing the compression spring 3122 to be in a contracted state. As the pre-connecting ring 31 gradually rotates, it gradually extends into the vessel body 1. When the pre-connecting ring 31 is fully connected to the vessel body 1, the positioning pin 3125 remains outside the vessel body 1, with its end protruding beyond the pre-connecting ring 31. At this point, the operator pulls out the positioning pin 3125, removing its restraint and releasing the elastic force of the compression spring 3122. This pushes the bearing rod 3123, causing the sealing ring 3121 to fully press against the groove in the conveying pipe 2, thereby further enhancing the sealing performance. It is worth noting that when the positioning pin 3125 has not been pulled out, the sealing ring 3121 is located in the groove of the conveying pipe 2, but the sealing ring 3121 is not subjected to the elastic force of the compression spring 3122. Therefore, the friction between the sealing ring 3121 and the inner wall of the groove is relatively small, and the operator can rotate the pre-connecting ring more easily.

[0024] The connecting flange 32 includes a snap-fit ​​plate 321 and a connecting plate 322. The snap-fit ​​plate 321 is fitted onto the conveying pipe 2. The snap-fit ​​plate 321 has a receiving groove corresponding to the pre-connecting ring 31. The snap-fit ​​plate 321 and the connecting plate 322 are fixedly connected.

[0025] Since the fastening plate 321 is fitted onto the conveying pipe 2, the position of the connecting flange 32 can be pre-adjusted when rotating the pre-connecting ring 31, making it easier for the operator to rotate the pre-connecting ring 31. After the pre-connecting ring 31 is assembled, the position of the connecting flange 32 is readjusted again, and the connecting flange 32 is fixedly connected to the vessel body 1. At this time, the fastening plate 321 fastens onto the pre-connecting ring 31, that is, the pre-connecting ring 31 is embedded in the receiving groove on the fastening plate 321, thereby fully covering the pre-connecting ring 31 and further enhancing the sealing effect.

[0026] It is worth noting that only one conveying pipe 2 is shown in the attached diagram, but in reality, multiple conveying pipes 2 can be installed on the vessel body 1. Some of these conveying pipes 2 serve as input pipes, while others serve as output pipes. However, regardless of the number of conveying pipes 2, the aforementioned assembly method remains unchanged.
