Description

Technical Field

[0001] This utility model relates to the field of cooling jacket technology, specifically a cooling jacket for a reaction vessel. Background Technology

[0002] In reactor production operations, the cooling jacket is a key component for controlling the reaction temperature inside the reactor. Its ease of installation and environmental adaptability directly affect production efficiency and equipment stability.

[0003] Existing cooling jackets mostly adopt an integral structure, which not only requires a large installation space but also lacks flexibility when assembling for reactors of different sizes or in complex on-site conditions. Furthermore, subsequent maintenance requires disassembling the entire structure, which is cumbersome, time-consuming, and labor-intensive. Simultaneously, most jackets lack adjustable support mechanisms, making it difficult to achieve stable fixation on uneven ground or in scenarios with specific installation height requirements. Equipment vibration can easily cause the jacket to loosen its fit with the reactor body, affecting cooling efficiency and posing safety hazards. Additionally, traditional cooling jackets often have a hollow cavity structure, which can easily lead to short-circuit flow after the cooling medium enters, meaning the medium is discharged directly from the outlet without fully contacting the outer wall of the reactor, resulting in insufficient heat exchange and low cooling efficiency. Therefore, there is an urgent need for a new type of reactor cooling jacket to solve these problems. Utility Model Content

[0004] In view of the shortcomings of the prior art mentioned in the background, the present invention provides a cooling jacket for a reaction vessel.

[0005] This utility model overcomes the above technical problems by adopting the following technical solution:

[0006] A cooling jacket for a reactor includes a jacket body, an extension plate fixedly connected to the outer wall of the jacket body, and two jacket bodies. The two extension plates are fixedly connected to the outer circumferential wall of the reactor body by fixing nuts and fixing screws. The outer circumferential wall of the jacket body is respectively provided with an outlet pipe and an inlet pipe, and the outlet pipe is located above the inlet pipe.

[0007] The bottom of the jacket body is provided with a support component to ensure its stable installation;

[0008] The jacket body is equipped with a flow guiding component to improve the cooling effect.

[0009] Preferably, the flow guiding assembly includes a flow guiding plate fixedly connected to the inner circumferential wall of the jacket body, and a sealing ring fixedly connected to one end of the flow guiding plate away from the inner circumferential wall of the jacket body, the sealing ring abutting against the outer circumferential wall of the vessel body.

[0010] Preferably, the guide plate is spirally arranged inside the jacket body, and the pitch of the guide plate gradually decreases from bottom to top.

[0011] Preferably, a sealing groove with a continuous left-right bend is formed on one side of the outer wall of the extension plate, and a sealing strip is engaged inside the sealing groove.

[0012] Preferably, the inner walls at both the upper and lower ends of the jacket body are provided with mounting grooves, and a sealing ring is engaged inside the mounting groove to ensure that the jacket body fits and seals with the vessel body.

[0013] Preferably, the sealing ring includes a first sealing part and a second sealing part, wherein the second sealing part is in close contact with the outer circumferential wall of the vessel body.

[0014] Preferably, the support assembly includes a threaded rod fixedly connected to the bottom outer wall of the jacket body, one end of the threaded rod being threadedly connected to a threaded cylinder, and the bottom of the threaded cylinder being snapped into a base.

[0015] By adopting the above structure, this utility model has the following advantages compared with the prior art:

[0016] 1. This utility model adopts a split structure of two jacket bodies. It can be connected and fixed to the outer circumference of the vessel body by means of the extension plate of the outer wall, the fixing screw and the fixing nut. The installation operation is simple and the later maintenance is easier. At the same time, the support component at the bottom of the jacket is composed of a threaded rod, a threaded cylinder and a base. The support height can be flexibly adjusted by means of the threaded engagement of the threaded rod and the threaded cylinder, and the base provides stable support. It can adapt to different installation environments and greatly improve the overall installation stability.

[0017] 2. In order to prevent leakage of cooling medium and energy loss, this utility model has a multi-seal structure for the jacket. Specifically, a sealing strip is engaged in a continuous left-right bent sealing groove on the outer wall of one side of the extension plate, which can enhance the sealing performance at the joint of the two jacket bodies. At the same time, a sealing ring is engaged in the mounting groove on the inner wall of the upper and lower ends of the jacket body. The first sealing part fits the jacket and the second sealing part fits tightly against the vessel body, further strengthening the sealing effect between the jacket and the vessel body, reducing the problem of medium leakage and energy loss from multiple dimensions.

[0018] 3. In this utility model, the cooling effect can be effectively improved by the flow guiding component inside the jacket. Specifically, the spirally arranged flow guiding plate, together with the sealing ring that is far away from the inner wall of the jacket and close to the vessel body, can effectively prevent short circuit of the cooling medium and ensure that the medium flows along the outer wall of the vessel body. Moreover, the pitch of the flow guiding plate gradually decreases from bottom to top, which can extend the contact path and time between the medium and the upper part of the vessel body, improve the heat exchange efficiency, and achieve efficient cooling. At the same time, the multiple sealing structure reduces the risk of leakage, the support structure ensures the stability of the installation, and the flow guiding structure optimizes the heat exchange. The synergistic effect of multiple components reduces the probability of equipment failure and improves the reliability of long-term use. Attached Figure Description

[0024] 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.

[0025] Please see Figures 1-4 In this embodiment of the present invention, a cooling jacket for a reactor includes a jacket body 1, an extension plate 2 is fixedly connected to the outer wall of the jacket body 1, and there are two jacket bodies 1. The two extension plates 2 are fixedly connected to the outer circumferential wall of the reactor body 15 by fixing nuts 9 and fixing screws 8. The outer circumferential wall of the jacket body 1 is respectively provided with an outlet pipe 3 and an inlet pipe 4, and the outlet pipe 3 is located above the inlet pipe 4.

[0026] The bottom of the jacket body 1 is provided with a support component to ensure its stable installation;

[0027] The jacket body 1 is equipped with a flow guiding component to improve the cooling effect. It adopts a split double jacket body 1 design. With the connection structure of extension plate 2, fixing screw 8 and fixing nut 9, it can be assembled on the vessel body 15 without the need for overall sleeve, which reduces the requirements for installation space, adapts to different sizes of vessel bodies 15 and complex working conditions, and provides convenience for later inspection and maintenance.

[0028] Furthermore, the flow guiding assembly includes a flow guiding plate 10 fixedly connected to the inner circumference of the jacket body 1. A sealing ring 14 is fixedly connected to one end of the flow guiding plate 10 away from the inner circumference of the jacket body 1. The sealing ring 14 is pressed against the outer circumference of the vessel body 15. The flow guiding plate 10 can guide the cooling medium entering the jacket body 1, preventing the medium from flowing randomly. At the same time, the design of the sealing ring 14 pressing against the vessel body 15 can prevent the medium from forming a short-circuit channel between the jacket body 1 and the vessel body 15, ensuring that the cooling medium must fully contact the outer wall of the vessel body 15 along the flow guiding path, providing a structural guarantee for improving the heat exchange effect.

[0029] Furthermore, the guide plate 10 is spirally arranged inside the jacket body 1, and the pitch of the guide plate 10 gradually decreases from bottom to top. The spiral guide plate 10 can transform the flow path of the cooling medium into a spiral trajectory, which greatly extends the residence time of the medium inside the jacket body 1. The design of the pitch gradually decreasing from bottom to top can increase the path density of the medium when it flows in the upper part of the vessel body 15, further improving the contact frequency and contact area with the outer wall of the vessel body 15, and significantly enhancing the adequacy of heat exchange.

[0030] Furthermore, a sealing groove 13 with continuous left-right bends is provided on one side of the outer wall of the extension plate 2. A sealing strip 12 is snapped into the inside of the sealing groove 13. The continuous left-right bends of the sealing groove 13 can increase the contact area between the sealing strip 12 and the extension plate 2, improve the stability of the sealing structure, and at the same time, the bend structure can form multiple barriers to the cooling medium that may leak. Together with the sealing strip 12 snapped into the sealing groove 13, it effectively enhances the sealing performance at the joint of the two jacket bodies 1, and reduces medium leakage and energy loss.

[0031] Furthermore, mounting grooves are provided on the inner walls of both the upper and lower ends of the jacket body 1. A sealing ring 11 is engaged inside the mounting groove to ensure a tight seal between the jacket body 1 and the vessel body 15. The mounting groove provides a stable mounting position for the sealing ring 11, preventing it from shifting during equipment operation. The sealing ring 11 engaged in the mounting groove can fill the gap between the jacket body 1 and the vessel body 15, forming an effective sealing barrier to prevent the cooling medium from leaking from both the upper and lower ends of the jacket body 1, further ensuring the sealing effect.

[0032] Furthermore, the sealing ring 11 includes a first sealing part 1101 and a second sealing part 1102. The second sealing part 1102 is in close contact with the outer circumferential wall of the vessel body 15. The first sealing part 1101 of the sealing ring 11 can be tightly fitted with the inner wall of the mounting groove of the jacket body 1, while the second sealing part 1102 is in close contact with the outer circumferential wall of the vessel body 15, forming a "double fit" sealing structure. This design can adapt to the assembly gap between the jacket body 1 and the vessel body 15, further improving the tightness of the seal and reducing the risk of leakage.

[0033] Furthermore, the support assembly includes a threaded rod 5 fixedly connected to the bottom outer wall of the jacket body 1. One end of the threaded rod 5 is threadedly connected to a threaded cylinder 6, and the bottom of the threaded cylinder 6 is snapped with a base 7. By utilizing the threaded engagement between the threaded rod 5 and the threaded cylinder 6, the overall height of the support assembly can be flexibly adjusted by rotating the threaded cylinder 6 to adapt to specific installation height requirements. The base 7 at the bottom can increase the contact area with the support surface, improve the stability of the support, and prevent the jacket body 1 from loosening due to equipment vibration.

[0034] Working principle: During installation, the two jacket bodies 1 are fixed to the outer circumference of the vessel body 15 by connecting the extension plate 2, the fixing screw 8 and the fixing nut 9. The sealing strip 12 in the continuous left and right bent sealing groove 13 on the extension plate 2 can enhance the sealing performance at the joint and prevent the cooling medium from leaking. At the same time, the sealing rings 11 (including the second sealing part 1102 that is close to the vessel body 15 and the first sealing part 1101 that is close to the jacket) in the mounting grooves at the upper and lower ends of the jacket body 1 further ensure the sealing effect between the jacket and the vessel body 15 and reduce energy loss.

[0035] Meanwhile, the support assembly at the bottom of the jacket adjusts its height through the threaded engagement of the threaded rod 5 and the threaded cylinder 6, and is supported by the base 7. This adapts to different installation environments and improves overall installation stability. During cooling operations, the cooling medium enters the jacket body 1 from the inlet pipe 4 located below. Guided by the spirally arranged guide plate 10, it flows along the outer wall of the vessel body 15. The end of the guide plate 10 away from the inner wall of the jacket is sealed against the vessel body 15 through the sealing ring 14, which can prevent the medium from short-circuiting. Moreover, its pitch gradually decreases from bottom to top, which can increase the flow path of the medium in the upper part of the vessel body 15, thereby prolonging the contact time with the vessel body 15 and improving the contact efficiency, fully absorbing the heat of the vessel body 15. Finally, the heated medium is discharged from the outlet pipe 3 above, achieving efficient cooling and thus greatly improving the cooling efficiency and reliability. At the same time, the split structure of the double jacket also facilitates installation and maintenance.

[0036] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention.
