Description

Technical Field

[0001] This utility model belongs to the field of connection mechanism technology, specifically relating to a heat exchanger shell connection mechanism. Background Technology

[0002] Heat exchangers, as crucial devices for heat transfer between two or more fluids, are widely used in various fields such as chemical engineering, power generation, and HVAC. In practical applications, the connection stability and installation efficiency of the heat exchanger shell directly affect the overall performance and operating costs of the equipment.

[0003] Traditional heat exchanger shell connections typically use bolt and nut connections. This method requires inserting each bolt through the bolt holes on the flange and tightening the nuts, a cumbersome process that consumes significant manpower and time. This is especially true for large heat exchangers, where the large flange size and numerous bolts make installation even more time-consuming and labor-intensive. Furthermore, under long-term vibration and temperature variations, the bolts are prone to loosening, leading to leaks at the connection points. This not only affects the heat exchanger's efficiency but can also potentially cause safety hazards.

[0004] While some quick-connect technologies can improve installation speed, they often fail to guarantee connection stability. Under high pressure or vibration, the connection may shift or separate, failing to meet the requirements of heat exchangers under complex operating conditions. Utility Model Content

[0005] The purpose of this utility model is to provide a heat exchanger shell connection mechanism. By setting up a spring frame and a stop block, the initial connection of the first flange and the second flange can be completed quickly. At the same time, the top block locks the first connecting pipe and the second connecting pipe after they are connected, which can ensure the stability after installation. Thus, while ensuring the stability of installation, the installation efficiency of the heat exchanger shell body can be improved, and problems such as displacement and separation of the connection parts can be reduced, which cannot meet the requirements of heat exchangers under complex working conditions.

[0006] The specific technical solution adopted by this utility model is as follows:

[0007] A heat exchanger shell connection mechanism includes two supports, within which a heat exchanger shell body is fixedly connected. A first connecting pipe is fixedly connected to one side of the heat exchanger shell body, and the heat exchanger shell body and the first connecting pipe are in communication. A second connecting pipe is installed on one side of the first connecting pipe, and the second connecting pipe is in communication with the first connecting pipe. A first flange and a second flange are fixedly connected to the outer sides of both the first and second connecting pipes. Multiple elastic frames are fixedly connected to the outer side of the first flange. A stop block located below the second flange is fixedly connected to each elastic frame. A first groove is formed inside each of the multiple stop blocks. A top block is slidably connected inside the first groove. A lifting drive component is installed inside the first groove, and the lifting drive component is used to drive the top block to rise or fall.

[0008] Furthermore, the plurality of elastic frames include a U-shaped bracket fixedly connected to the outside of the first flange, two pull rods are inserted into the U-shaped bracket and the two pull rods pass through the U-shaped bracket, and a return spring is sleeved on the outside of the pull rod.

[0009] Furthermore, the lower end of the stop block is an inclined end face, and the end of the inclined end face of the stop block away from the pull rod is inclined upward.

[0010] Furthermore, the lifting drive component is a screw, and the screw is rotatably connected inside the second groove. The upper end of the screw extends into the first groove and is threadedly connected to the top block.

[0011] Furthermore, a first groove is provided on the lower side of the top block, and a nut located in the first groove is fixedly connected to the lower end of the screw.

[0012] Furthermore, a limit block is fixedly connected to the upper side of the top block near the return spring.

[0013] The technical effects achieved by this utility model are as follows:

[0014] This utility model discloses a heat exchanger shell connection mechanism that can quickly complete the initial connection of the first flange and the second flange through the setting of the elastic frame and the stop block. At the same time as the connection is completed, the top block locks the first connecting pipe and the second connecting pipe a second time, which can ensure the stability after installation. Thus, while ensuring the installation stability, it can improve the installation efficiency of the heat exchanger shell body and reduce the problems of displacement and separation of the connection parts, which are prone to problems and cannot meet the requirements of heat exchanger use under complex working conditions.

[0021] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0022] As shown in Figure 1- Figure 4 As shown, a heat exchanger shell connection mechanism includes two supports 4, with a heat exchanger shell body 1 fixedly connected inside the two supports 4. A first connecting pipe 2 is fixedly connected to one side of the heat exchanger shell body 1, and the heat exchanger shell body 1 and the first connecting pipe 2 are connected. A second connecting pipe 5 is installed on one side of the first connecting pipe 2, and the second connecting pipe 5 is connected to the first connecting pipe 2. A first flange 3 and a second flange 7 are fixedly connected to the outer sides of both the first connecting pipe 2 and the second connecting pipe 5. Multiple elastic frames are fixedly connected to the outer side of the first flange 3, and a stop block 8 located below the second flange 7 is fixedly connected to the elastic frame. A first groove 14 is opened inside the multiple stop blocks 8, and a top block 11 is slidably connected inside the first groove 14. A lifting drive component is installed inside the first groove 14, and the lifting drive component is used to drive the top block 11 to rise or fall.

[0023] In use, connect the first connecting pipe 2 and the second connecting pipe 5 together. Then, place the first flange 3 on the upper side of the second flange 7. Move the stop block 8 to make the stop block 8 and the second flange 7 misaligned. Continue to move the first flange 3 downward so that the upper surface of the stop block 8 is lower than the lower surface of the second flange 7. Under the action of the spring frame, the stop block 8 is pushed to the lower side of the second flange 7, limiting the second flange 7 and completing the initial connection of the first flange 3 and the second flange 7. After adjustment, the lifting drive component drives the top block 11 to rise and tighten the second flange 7, thus completing the secondary locking. Then, the spring frame and the top block 11 can quickly complete the initial connection of the first flange 3 and the second flange 7. At the same time as completing the connection, after adjustment, the top block 11 is used to lock the heat exchanger shell body 1 and the second connecting pipe 5 a second time, which can ensure the stability after installation. Thus, while ensuring installation stability, it can also improve the stability of the heat exchanger shell body 1 and the second connecting pipe 5. The installation efficiency and connection stability are poor, and problems such as displacement and separation of the connection parts are reduced, which cannot meet the requirements of heat exchangers under complex operating conditions.

[0024] As shown in Figures 2 and 3, the multiple elastic frames include a U-shaped bracket 6 fixedly connected to the outside of the first flange 3. Two pull rods 9 are inserted into the U-shaped bracket 6 and pass through the U-shaped bracket 6. A return spring 10 is sleeved on the outside of the pull rod 9. In use, when it is necessary to install or separate the first flange 3 and the second flange 7, pulling the pull rod 9 will drive the stop block 8 to move away from the second flange 7, so that the stop block 8 and the second flange 7 are misaligned, and the first flange 3 and the second flange 7 can be installed or separated. After installation or separation, the elastic potential energy stored in the return spring 10 will push the stop block 8 to move to the lower side of the second flange 7. At this time, the stop block 8 limits the lower side of the second flange 7, which can control the distance between the first flange 3 and the second flange 7, thereby realizing the connection stability of the first connecting pipe 2 and the second connecting pipe 5.

[0025] As shown in Figures 3 and 4, the lower end of the stop block 8 is an inclined end face. The end of the inclined end face of the stop block 8 away from the tie rod 9 is inclined upward. When a downward force is applied to the upper first flange 3, the inclined end face of the bottom of the stop block 8 contacts the lower second flange 7. At this time, the downward thrust on the stop block 8 will be converted into a horizontal thrust under the action of the inclined end face, so that the stop block 8 will automatically move away from the second flange 7. Thus, the movement of the stop block 8 can be completed automatically during the installation process, reducing the difficulty of installation.

[0026] like Figure 4 As shown, the lifting drive component is a screw 12, which is rotatably connected inside the second groove 13. The upper end of the screw 12 extends into the first groove 14 and is threadedly connected to the top block 11. In use, the operator rotates the screw 12 to drive the top block 11 to move up and down, thereby completing a secondary locking of the two first flanges 3 and the second flange 7. Its structure is relatively simple, and its stability is high after locking.

[0027] As shown in Figure 1, a first groove 14 is provided on the lower side of the inside of the top block 11, and a nut 15 located in the first groove 14 is fixedly connected to the lower end of the screw 12. In use, by hiding the screw 12 inside the second groove 13, the phenomenon of the top block 11 getting stuck during the sliding process on the stop block 8 can be effectively reduced.

[0028] As shown in Figures 3 and 4, a limiting block 16 is fixedly connected to the upper side of the top block 11 near the return spring 10. The limiting block 16 can limit the side of the second flange 7.

[0029] The working principle of this utility model is as follows: In use, the first connecting pipe 2 and the second connecting pipe 5 are connected together. Then, the first flange 3 is placed on the upper side of the second flange 7. The stop block 8 is then moved to make the stop block 8 and the second flange 7 misaligned. The first flange 3 is moved downward so that the upper surface of the stop block 8 is lower than the lower surface of the second flange 7. Under the action of the elastic frame, the stop block 8 is pushed to the lower side of the second flange 7, limiting the second flange 7 and completing the initial connection of the first flange 3 and the second flange 7. After adjustment, the top block 11 is raised by the lifting drive to tighten the second flange 7, thus completing the secondary locking. Then, the initial connection of the first flange 3 and the second flange 7 can be quickly completed by the setting of the elastic frame and the top block 11. At the same time as the connection is completed, the top block 11 is used to lock the heat exchanger shell body 1 and the second connecting pipe 5 after adjustment, which can ensure the stability after installation. Thus, while ensuring the stability of the installation, the heat exchanger shell body 1 and the second connecting pipe 5 are also improved. The installation efficiency and connection stability are poor, and problems such as displacement and separation of the connection parts are reduced, which cannot meet the requirements of heat exchangers under complex operating conditions.

[0030] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
