Description

Technical Field

[0001] This utility model relates to the field of pressure vessel technology, and in particular to high-pressure reaction vessels for special equipment. Background Technology

[0002] High-pressure reaction vessels, as a type of sealed equipment specifically designed for various chemical reactions under high pressure, are widely used in many important fields such as chemical industry, pharmaceutical industry, and energy industry. Whether in the production of chemical products, the synthesis of pharmaceuticals, or the development of energy materials, high-pressure reaction vessels play an irreplaceable role and have become one of the key pieces of equipment in modern industry.

[0003] In various industrial and experimental applications, the top cover of high-pressure reaction vessels is usually sealed and fixed by bolts. While this method can ensure the airtightness and stability of the vessel to a certain extent, if the top cover connection fails or loosens for any reason, it is very likely to cause the top cover to eject. This phenomenon not only poses a great threat to the life safety of on-site operators. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a special high-pressure reaction vessel, which aims to improve the problem that existing high-pressure reaction vessels cannot prevent the top cover from popping up.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-pressure reaction vessel for special equipment, including a reaction vessel as the main body of the reaction vessel; an inner cover as a sealing cover of the reaction vessel, installed on the top of the reaction vessel; a connecting assembly for connecting the inner cover and the reaction vessel; a protective structure for preventing the inner cover from accidentally flying off, including a buffer mechanism and an installation mechanism; the buffer mechanism includes an outer cover, the inner cover is slidably connected to the inside of the reaction vessel, a fixing block one is fixedly connected to the top of the inner cover, a transmission rod is rotatably connected inside the fixing block one, a fixing block two is rotatably connected to one side of the transmission rod, a sliding block is fixedly connected to the top of the fixing block two, a sliding rod is fixedly connected to the inner wall of the outer cover, the sliding block is slidably connected to the outer wall of the sliding rod, a spring is sleeved on the outer wall of the sliding rod, a limit block is fixedly connected to one end of the sliding rod, and rotating blocks are rotatably connected to the outer walls of both the fixing block two and the fixing block one, with dampers installed on the outer walls of the rotating blocks.

[0006] Furthermore, the connecting assembly includes flange one and flange two. Flange one is fixedly installed on the outer wall of the reactor, and flange two is fixedly installed on the outer wall of the inner cover. Flange one and flange two are fixed together by bolts.

[0007] Furthermore, the mounting mechanism includes a rotating frame, which is mounted on the outer wall of the outer cover, and an mounting ring is fixedly connected to the outer wall of the reactor.

[0008] Furthermore, a connecting rod is rotatably connected inside the rotating frame, and a fixing plate is fixedly connected to the bottom of the connecting rod.

[0009] Furthermore, the mounting ring has a mounting hole inside.

[0010] Furthermore, the fixing plate has a second mounting hole inside.

[0011] Furthermore, the first mounting hole corresponds to the second mounting hole.

[0012] Furthermore, the first mounting hole and the second mounting hole are fixed together by bolts.

[0013] This utility model has the following beneficial effects:

[0014] 1. In this utility model, when the inner cover accidentally pops up, the outer cover will prevent the inner cover from flying off. At the same time, the force is transmitted through the transmission rod and the sliding block to disperse the force, and the sliding rod and the damper will provide buffering to prevent damage to the outer cover and the inner cover. This solves the problem that the top cover of the high-pressure reaction vessel cannot prevent it from popping up, and improves the safety of the high-pressure reaction vessel.

[0015] 2. In this utility model, during installation, flange one and flange two will install the inner cover on the top of the reactor, while the outer cover will be installed by rotating the connecting rod to make the fixing plate coincide with the mounting ring. Then, the outer cover will be connected to the mounting ring through mounting hole two and mounting hole one, thus fixing the outer cover to the reactor, thereby improving the convenience of using the reaction vessel.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Reference Figure 1-3 This utility model provides an embodiment of a special equipment high-pressure reaction vessel, comprising: a reaction vessel 1, serving as the main body of the reaction vessel; an inner cover 3, serving as a sealing cover for the reaction vessel, installed on the top of the reaction vessel 1; a connecting assembly for connecting the inner cover 3 and the reaction vessel 1; and a protective structure for preventing the inner cover 3 from accidentally flying off, including a buffer mechanism and an installation mechanism. The buffer mechanism includes an outer cover 2, the inner cover 3 is slidably connected to the inside of the reaction vessel 1, a fixing block 12 is fixedly connected to the top of the inner cover 3, a transmission rod 19 is rotatably connected inside the fixing block 12, a fixing block 2 18 is rotatably connected to one side of the transmission rod 19, a sliding block 13 is fixedly connected to the top of the fixing block 2 18, a sliding rod 14 is fixedly connected to the inner wall of the outer cover 2, the sliding block 13 is slidably connected to the outer wall of the sliding rod 14, a spring 15 is sleeved on the outer wall of the sliding rod 14, a limit block 20 is fixedly connected to one end of the sliding rod 14, and a rotating block 16 is rotatably connected to the outer walls of both the fixing block 2 18 and the fixing block 12, with a damper 17 installed on the outer wall of the rotating block 16.

[0023] Specifically, in the actual use of this high-pressure reaction vessel, the operator can install flange 29 on the pre-set position of flange 18 on the outer wall of the reactor 1, and then use a threaded connection to tightly fix the two flanges together. In this way, the inner cover 3 can be tightly sealed to the reactor 1. At the same time, by operating the connecting rod 5 to rotate on the rotating frame 4, the fixing plate 6 at the bottom of the connecting rod 5 can be made to fit with the mounting ring 7 designed on the outer wall of the reactor 1. On this basis, the mounting hole 10 inside the mounting ring 7 is connected to the mounting hole 21 inside the fixing plate 6, and the two are also firmly fixed together with bolts, thereby ensuring a stable connection between the outer cover 2 and the reactor 1.

[0024] During the reaction process, if an unexpected situation occurs that causes the inner cover 3 to fly off due to excessive pressure, the inner cover 3 will slide inward along a preset trajectory into the internal space of the outer cover 2. At this time, the outer cover 2 can effectively confine the inner cover 3 inside, preventing the inner cover 3 from flying out due to inertia, thereby avoiding possible safety accidents. In addition, during the process of the inner cover 3 sliding inward into the outer cover 2, the transmission rod 19 will effectively transmit the force on the inner cover 3 to the sliding block 13, and the sliding block 13 will slide smoothly along the sliding rod 14. This can evenly distribute the impact force on the inner cover 3 to various parts of the outer cover 2, avoiding structural damage to the outer cover 2 and the inner cover 3 due to direct impact.

[0025] More importantly, during the process of the transmission rod 19 transmitting force to the sliding block 13, the damper 17 effectively absorbs and buffers the transmitted force, thereby further reducing the impact of the impact force on the entire mechanism. At the same time, during the process of force dispersion by the sliding block 13, the spring 15 also performs a buffering function, absorbing part of the impact force through its elastic deformation, thereby providing more comprehensive and reliable protection for the entire mechanism and the outer cover 2.

[0026] Working principle: When using this high-pressure reaction vessel, flange 29 can be installed on flange 8 on the outer wall of reactor 1, and the two are fixed together by threads, thereby sealing the inner cover 3 to reactor 1. Simultaneously, the connecting rod 5 rotates on the rotating frame 4, causing the fixing plate 6 at the bottom of the connecting rod 5 to engage with the mounting ring 7 on the outer wall of reactor 1. The mounting ring 7 is then installed through mounting hole 10 and mounting hole 11 inside the fixing plate 6, and the two are fixed together with bolts, thus securing the outer cover 2 to reactor 1. Therefore, if an accident occurs during the reaction and causes the inner cover 3 to fly off, the inner cover 3 can... The outer cover 2 slides inward, thereby restricting the inner cover 3 and preventing it from flying out. As the inner cover 3 slides inward, the transmission rod 19 transmits force to the sliding block 13, which slides along the sliding rod 14, distributing the force to the outer cover 2 and preventing direct impact damage to the outer cover 2 and the inner cover 3. At the same time, when the transmission rod 19 transmits force to the sliding block 13, the damper 17 absorbs the force, thus buffering the force. In the process of distributing the force, the sliding block 13 is also buffered by the spring 15, thus protecting the mechanism and the outer cover 2.

[0027] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
