Description

Technical Field

[0001] This utility model belongs to the technical field of plate heat exchangers, and in particular relates to a plate heat exchanger that is easy to disassemble. Background Technology

[0002] Plate heat exchangers, as a high-efficiency heat exchange device, are constructed from a series of meticulously designed stacked metal plates. These plates, with their distinctive corrugated shape, cleverly form thin and uniform rectangular fluid channels. This design not only promotes efficient heat transfer between liquids and vapors but also endows plate heat exchangers with numerous superior characteristics: excellent heat transfer efficiency, extremely low heat loss, compact and lightweight structural design, significant space-saving effect, wide application adaptability, and long service life. Notably, under the same pressure drop conditions, their heat transfer coefficient is 3 to 5 times higher than that of traditional tube heat exchangers, while their footprint is reduced to one-third of the latter, and their heat recovery efficiency reaches an astonishing 90% or more. Plate heat exchangers are mainly divided into two categories: frame type (also known as detachable type) and brazed type, while the plates mainly present three forms: herringbone corrugation, horizontal straight corrugation, and nodular shape, to meet the needs of different application scenarios.

[0003] In the precision assembly process of plate heat exchangers, the carefully prepared plates and sealing gaskets are first skillfully suspended on the guide beam frame between the fixed and movable clamping plates. Then, using 8 to 10 sturdy bolts, they are precisely threaded through the fixed and movable clamping plates from all sides. By finely adjusting the tightness of the nuts and bolts, the entire plate heat exchanger structure is ensured to fit seamlessly, thus maintaining its excellent sealing performance. However, traditional assembly methods often place a significant physical burden on operators during assembly and disassembly, and the process is cumbersome and time-consuming, urgently requiring optimization to improve efficiency and convenience.

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this utility model.

[0023] Please see Figure 1A disassembleable plate heat exchanger is disclosed, relating to the field of plate heat exchanger technology. The heat exchanger includes a fixed clamping plate 1, which, as one of the basic structures of the heat exchanger, serves to support and fix the heat exchange plates 5. It ensures the stability of the heat exchange plates 5 during operation, preventing displacement due to pressure or vibration. A fixed guide beam 3 is fixedly connected to one side of the fixed clamping plate 1, providing a sliding track for the heat exchange plates 5. This facilitates easy sliding of the heat exchange plates 5 during installation and disassembly, improving maintenance efficiency. Simultaneously, the fixed guide beam 3 also increases the overall structural strength of the heat exchanger. Foot 8 is fixedly welded to the fixed clamping plate 1, used to fix the fixed clamping plate 1 (and thus the entire heat exchanger) to the ground. This ensures the stability and safety of the heat exchanger during operation, preventing it from moving or tipping over due to external forces. An inlet / outlet 9 is fixedly connected to the other side of the fixed clamping plate 1, used to connect the internal flow channels of the heat exchanger to the external piping system. The heat exchange medium can be easily introduced and discharged through the inlet and outlet ports 9, realizing heat exchange and transfer. Several heat exchange plates 5 are slidably installed on the fixed guide beam 3. The heat exchange plates 5 are the core components of the heat exchanger, responsible for realizing heat exchange. They are slidably installed on the fixed guide beam 3, which can be easily installed and disassembled, facilitating maintenance and replacement. A movable clamping plate 2 is connected to the other side of the fixed guide beam 3. A movable clamping plate 10 connected to the fixed guide beam is detachably installed on the outer side of the movable clamping plate 2. The movable clamping plate has a cross-shaped structure. The movable clamping plate 2 cooperates with the fixed clamping plate 1 to clamp the heat exchange plates 5. By adjusting the position and tightness of the movable clamping plate 2, a good seal and contact can be ensured between the heat exchange plates 5, improving heat exchange efficiency. Fastening screws 4 are hinged to both sides of the fixed clamping plate 1. The fastening screws 4 are hinged to both sides of the fixed clamping plate 1 and connected to the outer side of the cross-shaped movable clamping plate. By rotating the fastening screw 4, the clamping force of the movable clamping plate 2 on the heat exchange plates 5 can be adjusted, thereby ensuring good sealing and heat exchange performance. Simultaneously, the design of the fastening screw 4 also makes disassembly and reinstallation easier. The other end of the fastening screw 4 is connected to a cross-shaped movable clamping plate, the outer side of which is threaded with a nut. The nut is threaded onto the outer side of the cross-shaped movable clamping plate and engages with the fastening screw 4. Tightening the nut further secures the position of the movable clamping plate 2 and the heat exchange plates 5, ensuring the stability and safety of the heat exchanger. Furthermore, the nut design makes adjustment and maintenance simpler and more convenient.

[0024] Preferably, the fixed guide beams 3 are symmetrically distributed at the top and bottom of the fixed clamping plate 1. This symmetrical distribution design makes the heat exchanger structurally more stable, capable of withstanding forces from different directions, and reducing deformation or damage caused by uneven stress. Simultaneously, the symmetrically distributed fixed guide beams 3 also provide more uniform support for the heat exchange plates 5, ensuring their stability and heat exchange efficiency during operation. The fastening screws 4 are symmetrically distributed on both sides of the fixed clamping plate 1. This symmetrical distribution of the fastening screws 4 ensures that the movable clamping plate 2 receives uniform force during tightening, thereby better clamping the heat exchange plates 5. This design not only improves the sealing performance of the heat exchanger but also reduces stress concentration caused by uneven tightening, extending the service life of the heat exchanger. The heat exchange plates 5 are evenly distributed on the outer wall of the fixed guide beams 3. This evenly distributed distribution of the heat exchange plates 5 ensures the uniformity of the internal flow channels of the heat exchanger, allowing the heat exchange medium to fully exchange heat with each heat exchange plate 5 as it flows through the heat exchanger. This design improves the heat exchanger's heat exchange efficiency and reduces heat loss caused by uneven flow channels. The fixed guide beam 3 has a smooth surface, which reduces friction during the sliding installation of the heat exchange plates 5, making the installation process smoother. This not only improves installation efficiency but also reduces wear and damage caused by friction, extending the service life of the heat exchanger and heat exchange plates 5. The heat exchange plates 5 are slidably connected to the fixed guide beam 3. This sliding connection design allows the heat exchange plates 5 to be easily installed and removed from the fixed guide beam 3, facilitating heat exchanger maintenance and replacement. This connection method not only improves maintenance efficiency but also reduces damage and waste caused by difficult disassembly.

[0025] Preferably, the fastening screw insertion holes 10-2 and fixed guide beam insertion holes 10-3 on both the vertical and horizontal clamping plates of the movable clamping plate 10 are round holes and / or U-shaped holes, symmetrically distributed. This design ensures that the movable clamping plate 10 can be firmly connected to the fixed guide beam 3 and the fastening screw 4. Through the insertion holes, the movable clamping plate 10 can be easily fixed to the heat exchanger, while ensuring its stability and safety during operation. The biggest advantage of the U-shaped hole design is that it eliminates the need for a precise insertion process. During installation, the worker only needs to place the fastening screw 4 or the fixed guide beam 3 into the U-shaped hole and then adjust its position to align it with the corresponding hole. This design greatly simplifies the installation process, improves installation efficiency, and reduces damage and waste caused by difficult insertion. Furthermore, the U-shaped hole can accommodate a certain range of dimensional deviations, making the assembly of the heat exchanger more flexible and convenient.

[0026] In a further preferred embodiment, the movable clamping plate 10 has a reinforcing part 10-1 integrally stamped to one side at its center, which significantly enhances the structural strength and load-bearing capacity of the movable clamping plate, optimizes the stress distribution under stress, simplifies the manufacturing process, and thus improves the stability and durability of the entire heat exchanger, ensuring its efficient and stable operation in harsh working environments.

[0027] The reinforcing part is welded to or integrally stamped with the vertical and horizontal clamping plates to form ribs 11, which effectively enhances the overall structural strength of the movable clamping plate 10, ensures its stability and durability when subjected to fastening force and pressure, and further improves the operational reliability of the heat exchanger.

[0028] A washer 6 is provided between the nut and the movable clamping plate. This effectively disperses the pressure generated during tightening, protects the movable clamping plate from damage, and enhances the stability of the connection. The presence of the washer increases friction, improves the anti-loosening effect, and simplifies the installation and maintenance process. Simultaneously, the washer can also fill tiny gaps through elastic deformation, improving the sealing performance of the connection. This technical feature ensures the high efficiency, stability, and safety of the plate heat exchanger during operation, extending the service life of the equipment.

[0029] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
