Description

Technical Field

[0001] This utility model relates to the field of gas heat exchange technology, and in particular to a high-pressure gas heat exchanger. Background Technology

[0002] High-pressure gas refers to gas compressed to a higher pressure state at a certain temperature. These gases are typically stored in closed containers and have a pressure higher than atmospheric pressure. A pressure heat exchanger is a device used to transfer heat between two fluids at different temperatures. By transferring heat from one fluid to another, it achieves temperature regulation and energy recovery. A high-pressure gas heat exchanger is a device used for gas heat exchange under high pressure. Its main function is to transfer heat from one medium to another through efficient heat conduction to regulate the gas temperature.

[0003] High-pressure gas heat exchangers are mainly used in fields requiring high-pressure gas heat transfer and temperature regulation, such as petrochemicals, natural gas processing, air separation equipment, and metallurgical industries. They are widely used in important fields such as natural gas liquefaction, gas compression and transportation, and thermal management in chemical reaction processes.

[0004] In existing technologies, some high-pressure gas heat exchangers are typically installed using bolts and welding. While these methods provide the necessary sealing and strength, maintenance and replacement are cumbersome, time-consuming, and require significant downtime. Furthermore, bolts and welded components are prone to corrosion or damage after prolonged exposure to high temperatures and pressures, further complicating disassembly and replacement. Therefore, this paper proposes a high-pressure gas heat exchanger to address these issues. Utility Model Content

[0005] This utility model proposes a high-pressure gas heat exchanger, which aims to improve the problem that some existing high-pressure gas heat exchangers cannot achieve rapid maintenance and replacement.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A high-pressure gas heat exchanger includes two base plates, one of which has a fixing mechanism fixedly connected to its top, the fixing mechanism having a heat exchanger fixedly connected to its top, and two buffer mechanisms fixedly connected to the tops of the two base plates.

[0008] The fixing mechanism includes a cylinder, a connecting column is fixedly connected to the driving end of the cylinder, a connecting plate is connected to the outer height of the connecting column, a conveying assembly for providing conveying is rotatably connected to both ends of the connecting plate, a rotating column is rotatably connected to the conveying assembly, an arc-shaped clamping plate is fixedly connected to the outer side of the rotating column, and a rubber pad is fixedly connected to the outer side of the arc-shaped clamping plate.

[0009] As a further description of the above technical solution:

[0011] As a further description of the above technical solution:

[0012] The buffer mechanism includes a bearing plate, the bottom of which is fixedly connected to the top of the base plate. A first fixing post is fixedly connected to the outside of the bearing plate. An elastic component that provides impact reduction is fixedly connected to the outside of the first fixing post. A second fixing post is fixedly connected to the elastic component. A connecting rod is rotatably connected to the outside of the second fixing post.

[0013] As a further description of the above technical solution:

[0014] The connecting rod is rotatably connected to a triangular plate, and a telescopic column is fixedly connected to the outside of the triangular plate. A spring is sleeved on the outside of the telescopic column.

[0015] As a further description of the above technical solution:

[0016] The elastic component includes a telescopic column two, the two ends of which are fixedly connected to the fixed column one and the fixed column two on the same side, and a spring two is sleeved on the outside of the telescopic column two.

[0017] As a further description of the above technical solution:

[0018] The arc-shaped clamping plate is rotatably connected to the outside of the rotating plate.

[0019] As a further description of the above technical solution:

[0024] 1. In this utility model, by starting the cylinder extension column to push upward, the connecting plate connected to it moves upward, and the connecting plate transmits the upward force to the rotating plate.

[0025] 2. In this utility model, the heat exchanger is fixed to the second fixed column, while the first fixed column is fixed to the bearing plate. When the heat exchanger is subjected to external force, the second telescopic column and the second spring in the two fixed columns absorb and squeeze out the force, and transmit the released force to the first telescopic column and the first spring in the lateral direction through the connecting rods on both sides, thereby buffering the force again, thus reducing the external force and improving the stability of the heat exchanger.

[0032] 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.

[0033] Reference Figures 1 to 3This utility model provides an embodiment of a high-pressure gas heat exchanger, comprising two base plates 1. The base plates 1 serve as the fundamental support for the entire high-pressure gas heat exchanger, and their overall shape is rectangular. They are made of sturdy and flat metal material, such as thick steel plates, with a smooth and rust-proof surface. This provides sufficient strength to support the various components above and withstand the pressures and vibrations generated during operation, while also ensuring the stability of the entire device when placed on the ground or other working areas. A fixing mechanism is fixedly connected to the top of one of the base plates 1. The fixing mechanism includes a cylinder 2. The cylinder 2, as a common linear power output device, has a cylindrical shape, and its outer shell is made of a sturdy metal material with good heat dissipation properties, such as aluminum alloy. The outer shell effectively protects the internal components such as the piston and cylinder, and also dissipates the heat generated by the cylinder 2 during operation, ensuring stable operation of the cylinder 2 for a long time. The drive end of the cylinder 2 is fixedly connected to a connecting column 3, which is a slender cylindrical metal rod made of hard material such as alloy steel. It can move up and down linearly along the axis of the cylinder 2 under the drive of the cylinder 2. The movement is smooth and stable, without any jamming or deflection. The connecting column 3 is connected to a connecting plate 4, which is made of metal such as stainless steel with a smooth surface. The connecting plate 4 transmits the power of the connecting column 3 to the transmission components at both ends, thereby realizing the clamping and fixing operation of the heat exchanger 10. The two ends of the connecting plate 4 are rotatably connected to the transmission components that provide transmission.

[0034] The conveying assembly includes a rotating plate 5, which is a rectangular plate made of metal, such as aluminum alloy. It plays a role in force transmission and position adjustment during the movement of the entire fixed mechanism. The rotating plate 5 is internally rotatably connected to the outside of the connecting plate 4. The rotating plate 5 is internally rotatably connected to limit posts 6, which are short cylinders made of metal, such as alloy steel, with a smooth surface. The limit posts 6 are connected to the rotating plate 5 and can rotate flexibly around their own axis within the rotating plate 5. Both ends of the limit posts 6 are also connected to other components, limiting and guiding the rotation range of the rotating plate 5 to ensure that the rotating plate 5 does not experience unexpected displacement or excessive rotation angle during rotation. The conveying assembly is also rotatably connected to a rotating column 7, which is also a cylindrical metal shaft made of high-strength alloy steel. The surface is smooth and finely processed, with good coaxiality. An arc-shaped clamping plate 8 is fixedly connected to the outside of the rotating column 7. The arc-shaped clamping plate 8 is a plate-shaped structure with a certain curvature. Its material is metal, such as stainless steel, with a smooth surface. The edges are usually ground to avoid sharp corners. The arc-shaped clamping plate 8 is rotatably connected to the outside of the rotating plate 5. A rubber pad 9 is fixedly connected to the outside of the arc-shaped clamping plate 8. The rubber pad 9 is made of rubber material with good elasticity and anti-slip properties, such as nitrile rubber. Its shape fits the outer surface of the arc-shaped clamping plate 8. The presence of the rubber pad 9 not only increases the friction between the arc-shaped clamping plate 8 and the heat exchanger 10, making the clamping more secure, but also plays a buffering role, avoiding damage to the surface of the heat exchanger 10 during the clamping process and protecting the integrity and performance of the heat exchanger 10 from being affected.

[0035] Reference Figure 1 , Figure 4The fixed mechanism is fixedly connected to the heat exchanger 10, which is the core component of the entire high-pressure gas heat exchanger to realize the heat exchange function. It has a complex and precise internal channel structure for the flow of high-pressure gas and the transfer of heat. The material is a metal with good thermal conductivity and resistance to high temperature and pressure, such as copper alloy, and is manufactured through precision processing to ensure smooth inner walls of the channels, reducing gas flow resistance and improving heat exchange efficiency. It can also withstand the pressure from the high-pressure gas and the temperature changes generated during heat exchange, ensuring long-term stable operation of the heat exchanger. Two buffer mechanisms are fixedly connected to the top of the two base plates 1. The buffer mechanisms include a bearing plate 11, which is a flat rectangular plate made of metal, such as stainless steel, with a smooth and flat surface. The bottom of plate 11 is fixedly connected to the top of base plate 1. A fixed post 17 is fixedly connected to the outside of plate 11. Fixed post 17 is a cylindrical rod made of high-strength alloy steel with a smooth and straight surface. An elastic component that reduces impact force is fixedly connected to the outside of fixed post 17. The elastic component includes a telescopic post 18. Both ends of telescopic post 18 are fixedly connected to the adjacent side of fixed post 17 and fixed post 19. A spring 15 is sleeved on the outside of telescopic post 18. Telescopic post 18 is a spiral elastic element made of high-quality spring steel with uniform spring wire thickness, a smooth surface, and good elasticity and fatigue resistance. One end of spring 15 is fixedly connected to the outside of fixed post 19, and the other end of spring 15 is connected to the outside of fixed post 17.

[0036] The elastic component is fixedly connected to a second fixed post 19, which is also a cylindrical rod made of high-strength alloy steel. A connecting rod 16 is rotatably connected to the outside of the second fixed post 19. The connecting rod 16 is a slender rod-like structure, which can be cylindrical or cuboid in shape and made of metal, such as alloy steel. It is connected to the second fixed post 19 through a pivot, allowing the connecting rod 16 to rotate around the pivot at a certain angle outside the second fixed post 19. Its rotation is flexible and stable, and it plays a role in force transmission and position adjustment during the movement of the buffer mechanism. A triangular plate 14 is rotatably connected inside the connecting rod 16. A telescopic post 12 is fixedly connected to the outside of the triangular plate 14. A spring 13 is sleeved on the outside of the telescopic post 12. One end of the spring 13 is connected to the outside of the bearing plate 11, and the other end of the spring 13 is connected to the outside of the triangular plate 14. The bearing plate 11 is fixedly connected to the outside of the two springs 13.

[0037] Working principle: First, cylinder 2 drives connecting column 3 to move up and down along the cylinder axis through its linear power output. The movement of connecting column 3 drives connecting plate 4, which in turn transmits power to the transmission assemblies at both ends. Under the guidance of limiting column 6, rotating plate 5 in the transmission assembly rotates around its own axis, ensuring that the rotation range is within the expected range. The movement of rotating plate 5 causes rotating column 7 to rotate, pushing arc-shaped clamping plate 8 fixed on it to clamp heat exchanger 10. The surface of arc-shaped clamping plate 8 is covered with rubber pad 9 to increase the friction between it and heat exchanger 10, ensuring a stable clamping and preventing damage to the surface of heat exchanger 10.

[0038] The heat exchanger 10 achieves the flow of high-pressure gas and heat transfer through its complex internal channel structure. During operation, the base plate 1 provides stable support, bearing the weight of the equipment and vibrations during operation. The heat exchanger is fixed to the second fixed column 19, while the first fixed column 17 is fixed to the supporting plate 11. When the heat exchanger is subjected to external forces, the second telescopic column 18 and the second spring 15 in the two fixed columns absorb and release the force, which is then transmitted to the transverse telescopic column 12 and the first spring 13 via the connecting rods 16 on both sides, further buffering the force. This reduces the impact of external forces, absorbs and cushions the shock during equipment operation, and protects the stability and durability of the entire structure. The entire device, through precise design and the use of high-strength materials, ensures stable operation over long periods under high pressure and high temperature environments.

[0039] 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.
