[0002] An autoclave is an industrial device used to carry out chemical reactions under high pressure. Some are equipped with stirring or heat transfer devices and are also called pressure vessels. The lid is equipped with pressure gauges, rupture membrane safety devices, vapor-liquid valves, and temperature sensors to facilitate monitoring of the reaction inside the vessel, adjusting the proportion of the medium inside the vessel, and ensuring safe operation.

[0003] In existing technology, a sealing ring is placed between the vessel lid and the vessel body, and the vessel body and the vessel lid are fixed together with bolts. The sealing ring is then compressed, and the gap between the vessel lid and the vessel body is sealed by the sealing ring to prevent leakage.

[0004] However, in actual use, since the sealing ring is made of rubber, it will age over a long period of time, which will lead to leakage between the reactor bodies. The leakage is not easily detected by the staff and is only discovered when the pressure inside the reactor continues to drop, resulting in waste. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a special sealing device for high-pressure reactors. It solves the problem that in actual use, the sealing ring is made of rubber, and long-term sealing will cause aging, resulting in leakage between the reactor bodies. The leakage is not easily detected by the staff and is only discovered when the pressure inside the reactor continues to drop, thus causing waste.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a sealing device for a high-pressure reactor, comprising a reactor body, a reactor cover mounted on the top of the reactor body, flanges mounted on the sides of the reactor body and the reactor cover that are close to each other, and the two flanges being fixedly connected together by fixing bolts.

[0007] Preferably, the sealing structure includes a sealing shell, which is disposed on the outer wall of the flange and fitted onto the outer wall of the vessel body; a pressure strip is fixedly connected to the inner wall of the sealing shell and abuts against the outer walls of the two flanges; a pressure gauge is installed on the outer wall of the sealing shell; and a limiting device is installed on the inner wall of the sealing shell. Through the cooperation of the pressure strip and the limiting device, the sealing shell is installed on the outer wall of the flange, so that the pressure strip seals between the two flanges, and the pressure gauge determines whether the vessel body is leaking.

[0011] Beneficial effects

[0012] This invention provides a sealing device specifically for high-pressure reactors. It offers the following advantages: This sealing device, through the cooperation of a sealing shell, a pressure strip, and a pressure gauge, installs the sealing shell on the outer walls of two flanges and fixes it with a limiting device. This ensures the pressure strip inside the sealing shell is pressed against the gap between the two flanges, thus securing and sealing the flanges to prevent leakage.

[0019] 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.

[0020] In actual use, since the sealing ring is made of rubber, it will age over a long period of time, which will lead to leakage between the reactor bodies. The leakage is not easily detected by the staff and is only discovered when the pressure inside the reactor continues to drop, resulting in waste.

[0021] In view of this, the present invention provides a sealing device for high-pressure reactors, which solves the problem that in actual use, the sealing ring is made of rubber and will age after a long period of sealing, resulting in leakage between the reactor bodies. The leakage is not easily detected by the staff and is only discovered when the pressure inside the reactor continues to drop, thus causing waste.

[0022] Those skilled in the art can connect the components in this case sequentially. The specific connection and operation sequence should refer to the working principle described below. The detailed connection methods are well-known technologies in the field. The working principle and process are mainly described below.

[0023] Example 1: By Figure 1-4 As can be seen, a special sealing device for a high-pressure reactor includes a reactor body 1, a reactor cover 11 installed on the top of the reactor body 1, and flanges 12 installed on the sides of the reactor body 1 and the reactor cover 11 that are close to each other. The two flanges 12 are fixedly connected together by fixing bolts 13. The special sealing device for a high-pressure reactor also includes a sealing structure 2 and an auxiliary device 3. The sealing structure 2 is installed on the outer wall of the flange 12; the auxiliary device 3 is installed between the reactor cover 11 and the reactor body 1. The sealing structure 2 seals the space between the reactor cover 11 and the reactor body 1, and the auxiliary device 3 seals the interior of the reactor body 1.

[0024] In the specific implementation process, it is worth noting that there are two flanges 12, which are fixedly connected to the lower outer wall of the lid 11 and the upper outer wall of the vessel body 1, respectively. When installing the lid 11, the two flanges 12 are fixed together with fixing bolts 13, which makes the installation stable. The sealing structure 2 is used to determine whether the vessel body 1 is leaking and to seal it. The auxiliary device 3 can seal the inside of the vessel body 1 to prevent leakage. The top of the lid 11 is used to connect the sealing stirring mechanism, which facilitates the stirring of the material inside the vessel body 1 and accelerates the reaction. At the same time, the lid 11 should also be designed with necessary devices such as a closable feed hopper according to actual needs. The technical solution described in this application is to solve the problem of the sealing effect between the vessel body 1 and the lid 11 deteriorating after long-term use. It does not involve the improvement of the above structure, so it is not described in detail.

[0025] Furthermore, the sealing structure 2 includes a sealing shell 21, a pressure strip 22, a pressure gauge 23, and a limiting device 24. The sealing shell 21 is disposed on the outer wall of the flange 12 and sleeved on the outer wall of the vessel body 1. The pressure strip 22 is fixedly connected to the inner wall of the sealing shell 21 and abuts against the outer walls of the two flanges 12. The pressure gauge 23 is installed on the outer wall of the sealing shell 21. The limiting device 24 is installed on the inner wall of the sealing shell 21. Through the cooperation of the pressure strip 22 and the limiting device 24, the sealing shell 21 is installed on the outer wall of the flange 12, so that the pressure strip 22 seals between the two flanges 12. The pressure gauge 23 determines whether the vessel body 1 is leaking. The material of the pressure strip 22 is rubber.

[0026] In the specific implementation process, it is worth noting that the pressure gauge 23 is a gas pressure gauge. When the vessel body 1 leaks, the pressure inside the sealing shell 21 will increase, causing the value on the pressure gauge 23 to change. The staff can judge whether the vessel body 1 is leaking by observing the value on the pressure gauge 23. The sealing shell 21 is semi-circular in shape. By joining two sealing shells 21 together, a complete sealing shell 21 is formed. A rubber gasket is placed between the two sealing shells 21 to prevent leakage between them. Sealing gaskets are also installed in the gaps between the sealing shell 21 and the vessel body 1 and the vessel cover 11 to prevent air leakage between the sealing shell 21 and the vessel body 1 and the vessel cover 11, which would affect the sealing effect. During installation, the pressure strip 22 is pressed against the gap connecting the two flanges 12 to achieve a seal and to determine whether there is a leak. Under the action of the limiting device 24, the sealing shell 21 is installed on the outer wall of the flange 12.

[0027] Furthermore, the limiting device 24 includes a clamping bolt 241, a rubber ring 242, and a clamping block 243. The clamping bolt 241 is threaded to the inner wall of the sealing shell 21, and one end extending into the interior of the sealing shell 21 is clamped against the top of the flange 12. The rubber ring 242 is sleeved on the outer wall of the clamping bolt 241 and clamps between the clamping bolt 241 and the sealing shell 21. The clamping block 243 is fixedly connected to the bottom of the inner wall of the sealing shell 21 and clamps against the bottom of the flange 12. Through the cooperation of the clamping block 243 and the rubber ring 242, the clamping bolt 241 fixes the sealing shell 21 to the outer wall of the flange 12.

[0028] In the specific implementation process, it is worth noting that the rubber ring 242 is made of rubber, and a clamping block 243 is fixedly connected to the bottom of the inner wall of the sealing shell 21. When installing the sealing shell 21, the clamping block 243 is pressed against the bottom of the flange 12, and the clamping bolt 241 is rotated so that the clamping bolt 241 is pressed against the top of the flange 12. In this way, the sealing shell 21 is fixed to the outer wall of the flange 12, and the rubber ring 242 is squeezed when the clamping bolt 241 is rotated, sealing the gap between the clamping bolt 241 and the sealing shell 21.

[0029] Specifically, when using this high-pressure reactor-specific sealing device, when installing the reactor cover 11 and reactor body 1, the auxiliary device 3 is installed between the reactor cover 11 and reactor body 1 to seal the interior of the reactor body 1. During installation, the upper and lower flanges 12 are aligned and fixed together using fixing bolts 13 to seal the reactor cover 11 and reactor body 1. Two semi-circular sealing shells 21 are fitted onto the outer walls of the two flanges 12, so that the abutting block 243 abuts against the bottom of the flange 12. The abutting bolt 241 is rotated to abut against the top of the flange 12, and the gap between the abutting bolt 241 and the flange 12 is sealed using rubber rings 242. In this way, the sealing shell 21 is fixed to the outer wall of the flange 12. When leakage occurs, the reading of the pressure gauge 23 on the outer wall of the sealing shell 21 will change, so that the staff can promptly inspect the reactor body 1.

[0030] Example 2: From Figure 1-4 It is known that the auxiliary device 3 includes a sealing ring 31 and an insert 32. The sealing ring 31 is pressed against the inner wall of the lid 11 and the body 1. The insert 32 is fixedly connected to the inner wall of the sealing ring 31 and inserted between the lid 11 and the body 1. The sealing ring 31 and the insert 32 work together to seal the body 1 and the lid 11.

[0031] In the specific implementation process, it is worth noting that when installing the vessel body 1 and the vessel cover 11, the insert 32 is pressed against the top of the vessel body 1, so that the vessel cover 11 is pressed against the top of the insert 32. In this way, when the two are fixed with the fixing bolts 13, the sealing ring 31 will be installed inside the vessel body 1 and the gap between the vessel cover 11 and the vessel body 1 will be sealed to prevent leakage. The materials of the sealing ring 31 and the insert 32 should not easily react with the substances inside the reactor. In this embodiment, the sealing ring 31 and the insert 32 are integrally molded to ensure the strength between the two. Fluororubber material can be used to ensure the sealing effect. At the same time, fluororubber material is stable and not easily affected by chemical materials to react, ensuring the durability of use. Of course, depending on the actual use of the vessel body 1, other suitable materials can be selected to make the sealing ring 31 and the insert 32 to meet the sealing and durability requirements.

[0032] Furthermore, a sealing gasket 14 is tightly abutted between the two flanges 12;

[0033] In the specific implementation process, it is worth noting that the sealing gasket 14 is made of rubber. When fixing the two flanges 12, the flanges 12 will be clamped to seal the gap between the vessel body 1 and the vessel cover 11 to prevent leakage.

[0034] Specifically, based on the above embodiments, when installing the vessel lid 11 and vessel body 1, the insert block 32 is inserted between the two, so that the sealing ring 31 is pressed against the gap between the vessel lid 11 and vessel body 1, thus achieving a seal and adding a layer of protection between the vessel body 1 and vessel lid 11. With the help of the pressure gauge 23, the staff can replace the sealing gasket 14 in a timely manner to avoid waste due to long-term leakage. In this way, between the vessel body 1 and vessel lid 11, from the inside to the outside, the sealing ring 31 and the insert block 32 form the first layer of seal, the sealing gasket 14 is the second layer of seal, the pressure strip 22 is the third layer of seal, and the sealing shell 21 is the fourth layer of seal. The multi-layer seal has a strong sealing effect, and once a leak occurs, it can be detected in time by the pressure gauge 23.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
