Abstract
Description
Technical Field
[0001] This utility model relates to the field of heat exchanger technology, and in particular to a plate heat exchanger structure. Background Technology
[0002] In 1923, R. Seligman of APV successfully designed a mass-producible plate heat exchanger. By using corrugated plates pressed from thin stainless steel and copper sheets, he significantly improved the heat transfer efficiency of the plate heat exchanger while also enhancing its structural strength and stability. This design laid the foundation for the commercial application of plate heat exchangers, leading to their widespread use in industrial production. With industrial development, the performance requirements for plate heat exchangers have continuously increased, further driving technological innovation. For example, optimizations have been made to the shape and corrugated structure of the plates, improvements to the sealing structure to enhance the sealing performance of the equipment, and optimization of fluid flow paths to enhance heat transfer. These improvements have enabled plate heat exchangers to play a vital role in numerous fields, such as refrigeration, HVAC, chemical engineering, and food processing.
[0003] However, traditional plate heat exchangers typically use bolted or flanged connections for piping. These methods are cumbersome, requiring significant time and manpower for installation and disassembly, resulting in low efficiency. Furthermore, bolts and other connectors are prone to loosening and corrosion over time, leading to decreased sealing performance and leaks. This not only wastes the heat exchange medium but can also disrupt normal equipment operation and even cause safety accidents, necessitating improvements. Utility Model Content
[0004] The purpose of this utility model is to solve the technical problems mentioned in the background art.
[0005] This utility model adopts the following technical solution: a plate heat exchanger structure, including a housing, with an inlet pipe and an outlet pipe fixedly installed on the front surface of the housing, and a sewage pipe and a discharge pipe fixedly installed on the rear surface of the housing. A torsion spring is fitted onto the outer surface of the inlet pipe, outlet pipe, sewage pipe, and discharge pipe. A rotating block is fitted onto the outer surface of the inlet pipe, outlet pipe, sewage pipe, and discharge pipe. A rack is fixedly installed on the inner surface of the rotating block, and a toothed column is fitted inside the rotating block. A gear is fixedly installed at one end of the toothed column. A limiting plate is fixedly installed on the outer surface of the inlet pipe, outlet pipe, sewage pipe, and discharge pipe. A toothed ring is fitted inside the limiting plate, and a rotating plate is fixedly installed at one end of the toothed ring. An arc-shaped groove is formed on the surface of the rotating plate, and a moving rod is fitted inside the arc-shaped groove. A clamping block is fixedly installed at one end of the moving rod, and a sliding rod is fixedly installed at one end of the clamping block. A sliding groove is formed on the surface of the inlet pipe, outlet pipe, sewage pipe, and discharge pipe.
[0006] Preferably, the sliding rod is fitted inside the sliding groove, which is a flat ellipse. There are four sets of sliding grooves, sliding rods, and clamping blocks, arranged circumferentially on the outer and inner surfaces of the inlet pipe, outlet pipe, sewage pipe, and discharge pipe. Here, the sliding rod fitted inside the flat elliptical sliding groove enables a stable sliding connection. The four sets of circumferentially distributed sliding grooves, sliding rods, and clamping blocks evenly clamp and fix the inlet pipe, outlet pipe, sewage pipe, and discharge pipe, ensuring the stability of the pipeline during operation and preventing pipe shaking or displacement from affecting the heat exchange effect.
[0007] Preferably, the outer surface of the rotating block is provided with anti-slip textures, which are multiple sets distributed circumferentially on the surface of the rotating block. The surface of the toothed column meshes with the surface of the rack, and the surface of the first gear meshes with the surface of the gear ring. Here, the multiple sets of circumferentially distributed anti-slip textures on the outer surface of the rotating block increase the friction between the operator's hand and the rotating block, preventing slippage and making the rotation operation more effortless and accurate.
[0008] Preferably, one end of the torsion spring is fixedly connected to the surface of the housing, and the other end of the torsion spring is fixedly connected to the rear end surface of the rotating block. The arc-shaped groove is a flattened ellipse. Here, one end of the torsion spring is connected to the housing, and the other end is connected to the rotating block. When the rotating block rotates, the torsion spring can automatically reset it, facilitating the next operation.
[0009] Preferably, the first gear, the gear ring, and the rotating plate are all fitted inside the limiting plate. The number of gear columns and the first gear are four sets, arranged circumferentially inside the limiting plate and the rotating block. Here, one end of the torsion spring is connected to the housing, and the other end is connected to the rotating block. When the rotating block rotates, the torsion spring can automatically reset it, facilitating the next operation.
[0010] Preferably, a fixing block is fixedly installed at the top of the housing, a limiting rod is fixedly installed on the surface of the fixing block, a movable block one is sleeved on the outer surface of the limiting rod, a spring one is sleeved on the outer surface of the limiting rod, a rotating column is sleeved inside the movable block one, a movable block two is sleeved inside the other end of the rotating column, a protective plate is fixedly installed at the top of the movable block two, and a spring two is fixedly installed at the bottom of the protective plate. Here, the fixing block, limiting rod, movable block one, spring one, rotating column, movable block two, protective plate, and spring two at the top of the housing constitute a protective structure.
[0011] Preferably, both ends of the first spring are connected and fixed to the surface of the first movable block, one end of the second spring is connected and fixed to the bottom surface of the protective plate, and the other end of the second spring is connected and fixed to the surface of the housing. Here, the two ends of the first spring are connected to the first movable block, providing elastic support and restoring force for the movement of the first movable block on the limiting rod, so that it can buffer and reset when subjected to external force.
[0012] Preferably, the protective plates are arranged in three sets, placed on the left, right, and top sides of the enclosure, respectively. Both ends of the rotating column are semi-circular, and the first and second movable blocks are semi-elliptical in shape. Here, the three sets of protective plates, placed on the left, right, and top sides of the enclosure, provide comprehensive protection, improving the safety and reliability of the equipment.
[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:
[0014] 1. This utility model employs a structure consisting of a housing, an inlet pipe, and an outlet pipe, connected by a rotating plate, a moving rod, and a clamping block. This connection method is simple and quick to operate; simply holding the rotating block and rotating it allows for easy connection and disconnection of external pipes, significantly saving time and manpower and greatly improving work efficiency. Furthermore, the components of this connection structure are less prone to loosening or corrosion, and the connection points have excellent sealing performance, effectively preventing leakage of the heat exchange medium. This not only ensures the full utilization of the heat exchange medium and avoids waste but also ensures stable and normal operation of the equipment, greatly reducing the risk of safety accidents and providing strong support for the reliable operation of the equipment.
[0015] 2. In this utility model, a protective structure is formed by setting up a fixed block, a limiting rod, a first movable block, a first spring, a rotating column, a second movable block, a protective plate, and a second spring at the top of the box. The first movable block can move on the limiting rod, and the first spring provides buffering and restoring force.

[0023] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.
[0024] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.
[0025] Example 1
[0026] Please see Figures 1-5This utility model provides a technical solution: a plate heat exchanger structure, including a housing 1. An inlet pipe 2 and an outlet pipe 3 are fixedly installed on the front surface of the housing 1. A sewage pipe 4 and a discharge pipe 5 are fixedly installed on the rear surface of the housing 1. A torsion spring 6 is sleeved on the outer surface of the inlet pipe 2, outlet pipe 3, sewage pipe 4, and discharge pipe 5. A rotating block 7 is sleeved on the outer surface of the inlet pipe 2, outlet pipe 3, sewage pipe 4, and discharge pipe 5. A rack 8 is fixedly installed on the inner surface of the rotating block 7. A gear 9 is sleeved inside the rotating block 7. A gear 10 is fixedly installed at one end of the gear 9. A limiting plate 11 is fixedly installed on the outer surface of the discharge pipe 5. A toothed ring 12 is fitted inside the limiting plate 11. A rotating plate 13 is fixedly installed at one end of the toothed ring 12. An arc-shaped groove 14 is formed on the surface of the rotating plate 13. A moving rod 15 is fitted inside the arc-shaped groove 14. A clamping block 16 is fixedly installed at one end of the moving rod 15. A sliding rod 17 is fixedly installed at one end of the clamping block 16. Sliding grooves 18 are formed on the surfaces of the inlet pipe 2, outlet pipe 3, sewage pipe 4, and discharge pipe 5. When using this plate heat exchanger structure, first observe the condition of the inlet pipe 2, outlet pipe 3 at the front end of the casing 1 and the sewage pipe 4 and discharge pipe 5 at the rear end. When it is necessary to connect an external pipe, grasp the rotating block 7 fitted on the outer surface of the inlet pipe 2, outlet pipe 3, sewage pipe 4, or discharge pipe 5 and rotate it. When the rotating block 7 rotates, the toothed rack 8 fixed on its inner surface also rotates. Since the gear 9 is fitted inside the rotating block 7 and its surface meshes with the surface of the rack 8, the rotation of the rack 8 drives the gear 9 to rotate. The gear 10 fixed at one end of the gear 9 rotates accordingly. Because the surface of the gear 10 meshes with the surface of the gear ring 12 fitted inside the limiting plate 11, the rotation of the gear 10 drives the gear ring 12 to rotate. When the gear ring 12 rotates, the rotating plate 13 fixed at one end also rotates. An arc-shaped groove 14 is formed on the surface of the rotating plate 13, and the moving rod 15 is fitted inside the arc-shaped groove 14. When the rotating plate 13 rotates, the moving rod 15 moves within the arc-shaped groove 14. The clamping block 16 fixed at one end of the moving rod 15 moves with the moving rod 15, and the sliding rod 17 fixed at one end of the clamping block 16 slides within the sliding groove 18 formed on the surface of the inlet pipe 2, outlet pipe 3, sewage pipe 4, or discharge pipe 5. Once the clamping block 16 is moved to the appropriate position, the external pipe is placed between the clamping blocks 16. The rotating block 7 is then rotated in the opposite direction, causing the clamping blocks 16 to gradually approach and clamp the external pipe, thus facilitating the connection between the external pipe and the inlet pipe 2, outlet pipe 3, sewage pipe 4, or discharge pipe 5. After connection, the rotating block 7 is released, and the torsion spring 6 fitted on the outer surface of the pipe will automatically reset the rotating block 7. During normal operation, the heat exchange medium enters the housing 1 from the inlet pipe 2 for heat exchange and then flows out through the outlet pipe 3. Sewage is discharged through the sewage pipe 4, and other substances requiring discharge are discharged through the discharge pipe 5.
[0027] Please see Figures 1-5The sliding rod 17 is fitted inside the sliding groove 18, which is a flat ellipse. There are four sets of sliding grooves 18, sliding rods 17, and clamping blocks 16, arranged circumferentially on the outer and inner surfaces of the inlet pipe 2, outlet pipe 3, sewage pipe 4, and discharge pipe 5. The outer surface of the rotating block 7 has anti-slip textures, arranged in multiple sets circumferentially on its surface. The surface of the toothed column 9 meshes with the surface of the rack 8, and the surface of the gear 10 meshes with the surface of the gear ring 12. One end of the torsion spring 6 is connected and fixed to the surface of the housing 1, and the other end is connected and fixed to the rear end surface of the rotating block 7. The arc-shaped groove 14 is a flat ellipse, and gear 10, gear ring 12, and rotating plate 13 are all fitted with it. Inside the limiting plate 11, there are four sets of toothed columns 9 and gears 10, which are distributed circumferentially inside the limiting plate 11 and the rotating block 7. Both ends of spring 22 are connected and fixed to the surface of moving block 21. One end of spring 26 is connected and fixed to the bottom surface of the protective plate 25, and the other end of spring 26 is connected and fixed to the surface of the box 1. There are three sets of protective plates 25, which are placed on the left, right and top sides of the box 1 respectively. Both ends of the rotating column 23 are semi-circular. The shapes of moving block 21 and moving block 24 are semi-elliptical. The semi-elliptical moving block 21 and moving block 24, together with other components, have a stable and beautiful structure, and are also convenient for installation and adjustment of the position of the protective plate 25.
[0028] Example 2
[0029] Please see Figures 1-2A fixing block 19 is fixedly installed at the top of the housing 1. A limiting rod 20 is fixedly installed on the surface of the fixing block 19. A movable block 21 is fitted on the outer surface of the limiting rod 20, and a spring 22 is fitted on the outer surface of the limiting rod 20. A rotating column 23 is fitted inside the movable block 21, and a movable block 24 is fitted inside the other end of the rotating column 23. A protective plate 25 is fixedly installed at the top of the movable block 24, and a spring 26 is fixedly installed at the bottom of the protective plate 25. When using the protective structure at the top of the housing 1 in this plate heat exchanger structure, the fixing block 19 can be seen fixedly installed at the top of the housing 1. The limiting rod 20 fixed on the surface of the fixing block 19 plays a key supporting and guiding role. When an external force is applied to the protective plate 25, the protective plate 25 will move downward. Since the spring 26 is fixedly installed at the bottom of the protective plate 25, the spring 26 will be compressed, absorbing part of the energy of the external impact and playing a preliminary buffering role. Simultaneously, the protective plate 25 is connected to the movable block 21 via the movable block 24 and the rotating column 23. The downward movement of the protective plate 25 causes the movable block 24 to move along the rotating column 23. The rotating column 23 rotates inside the movable block 21, causing the movable block 21 to slide downwards on the limiting rod 20. During the downward sliding of the movable block 21, the spring 22, which is fitted onto the outer surface of the limiting rod 20, is compressed. The spring 22 further absorbs the energy of the external impact, enhancing the buffering effect. When the external force disappears, the elastic potential energy stored in the spring 26 and the spring 22 is released. The spring 26 pushes the protective plate 25 upwards, and the spring 22 pushes the movable block 21 to slide upwards and reset on the limiting rod 20. As the movable block 21 slides upwards, the rotating column 23 causes the movable block 24 and the protective plate 25 to move upwards together, restoring the protective plate 25 to its original position and continuing to protect the housing 1.
[0030] Working Principle: When using this plate heat exchanger structure, first observe the condition of the inlet pipe 2, outlet pipe 3 at the front end of the housing 1, and the sewage pipe 4 and discharge pipe 5 at the rear end. When connecting external pipes, grasp the rotating block 7 that is fitted onto the outer surface of the inlet pipe 2, outlet pipe 3, sewage pipe 4, or discharge pipe 5 and rotate it. When the rotating block 7 rotates, the rack 8 fixed on its inner surface also rotates. Since the gear 9 is fitted inside the rotating block 7 and its surface meshes with the surface of the rack 8, the rotation of the rack 8 drives the gear 9 to rotate. The gear 10 fixed at one end of the gear 9 rotates accordingly. Because the surface of the gear 10 meshes with the surface of the gear ring 12 fitted inside the limiting plate 11, the rotation of the gear 10 drives the gear ring 12 to rotate. When the gear ring 12 rotates, the rotating plate 13 fixed at one end of it also rotates together. An arc-shaped groove 14 is formed on the surface of the rotating plate 13. The moving rod 15 is fitted inside the arc-shaped groove 14. When the rotating plate 13 rotates, the moving rod 15 moves within the arc-shaped groove 14. A clamping block 16 fixed at one end of the moving rod 15 moves with the moving rod 15, and a sliding rod 17 fixed at one end of the clamping block 16 slides within a sliding groove 18 formed on the surface of the inlet pipe 2, outlet pipe 3, sewage pipe 4, or discharge pipe 5. When the clamping block 16 moves to the appropriate position, the external pipe is placed between the clamping blocks 16, and the rotating block 7 is rotated in the opposite direction, causing the clamping blocks 16 to gradually approach and clamp the external pipe, thereby facilitating the connection between the external pipe and the inlet pipe 2, outlet pipe 3, sewage pipe 4, or discharge pipe 5. After the connection is completed, the rotating block 7 is released, and the torsion spring 6 fitted on the outer surface of the pipe will cause the rotating block 7 to automatically return to its original position. During normal operation, the heat exchange medium enters the housing 1 through the inlet pipe 2, undergoes heat exchange, and then flows out through the outlet pipe 3. Wastewater is discharged through the wastewater pipe 4, and other substances requiring discharge are discharged through the discharge pipe 5. When using the protective structure at the top of the housing 1 in this plate heat exchanger structure, a fixed block 19 is first visible at the top of the housing 1. The limiting rod 20 fixed on the surface of the fixed block 19 plays a crucial supporting and guiding role. When an external force is applied to the protective plate 25, the protective plate 25 will move downward. Since a second spring 26 is fixedly installed at the bottom of the protective plate 25, the second spring 26 will be compressed, absorbing some of the energy of the external impact and playing a preliminary buffering role. At the same time, the protective plate 25 is connected to the first moving block 21 through the second moving block 24 and the rotating column 23. The downward movement of the protective plate 25 will drive the second moving block 24 to move along the rotating column 23. The rotating column 23 rotates inside the first moving block 21, causing the first moving block 21 to slide downward on the limiting rod 20. As the movable block 21 slides downwards, the spring 22, which is fitted onto the outer surface of the limiting rod 20, is compressed. The spring 22 further absorbs the energy of the external impact, enhancing the buffering effect. When the external force disappears, the elastic potential energy stored in the spring 26 and the spring 22 is released. The spring 26 pushes the protective plate 25 upwards, and the spring 22 pushes the movable block 21 to slide upwards and reset on the limiting rod 20.When the first movable block 21 slides upward, it drives the second movable block 24 and the protective plate 25 to move upward together through the rotating column 23, so that the protective plate 25 returns to its original position and continues to protect the box 1.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
