Description

Technical Field

[0001] This utility model relates to the technical field of detachable plate heat exchangers, and in particular to a corrosion-resistant plate heat exchanger. Background Technology

[0002] Corrosion-resistant plate heat exchangers are heat exchange equipment that achieves efficient heat exchange through special corrugated plates and corrosion-resistant materials or coatings. They are widely used in fields with corrosive media, such as chemical, pharmaceutical, food and beverage, electroplating, and environmental protection industries, due to their convenient maintenance, high flexibility, and significant energy savings.

[0003] Corrosion-resistant plate heat exchangers are generally composed of plates, gaskets, pipes, frames, and other structures. Based on the general principle of plate heat exchangers, corrosion-resistant plate heat exchangers allow hot and cold fluids to flow through the channels between the plates. Heat conduction is achieved by utilizing the large specific surface area of ​​the plates and the temperature difference. At the same time, a protective film is formed by corrosion-resistant materials or coatings to resist fluid corrosion, improve heat exchange efficiency, and extend equipment life.

[0004] Existing corrosion-resistant plate heat exchangers cannot achieve rapid sealing and connection of pipelines. During installation, complex connection operations lead to low installation efficiency, significantly increasing installation costs and manpower consumption. Poor sealing performance during operation can easily cause corrosive fluid leakage, resulting in fluid waste, environmental and equipment corrosion, and threats to personnel safety. During maintenance, difficult connection significantly increases the difficulty of disassembly and reassembly, prolonging downtime. Repeated operations can further aggravate damage to the sealing structure and worsen leakage problems. Therefore, a corrosion-resistant plate heat exchanger is proposed to solve the above problems. Utility Model Content

[0031] 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.

[0032] Reference Figures 1 to 3 The present invention provides an embodiment of a corrosion-resistant plate heat exchanger, comprising a connecting plate 1. The connecting plate 1 serves as the basic connecting component of the entire corrosion-resistant plate heat exchanger, providing a stable installation platform for other components, ensuring that each component maintains a relatively fixed positional relationship during operation, and ensuring the stability of the overall structure of the equipment. A bracket 4 is fixedly connected to its rear side, which plays a supporting and reinforcing role, sharing the weight and pressure borne by the connecting plate 1, enhancing the overall rigidity of the equipment, and making it less prone to deformation when subjected to fluid pressure and mechanical vibration.

[0033] Multiple pipes 2 are fixedly connected inside the connecting plate 1. The pipes 2 are used to guide fluids of different temperatures into and out of the heat exchanger. They cooperate with the plates 3 to achieve heat exchange. Their distribution and structural design can reasonably allocate the fluid flow rate, ensure that the fluid flows evenly in the heat exchanger, and improve the heat exchange efficiency. Multiple plates 3 are slidably connected to the outside of the pipes 2. The plates 3 are the core components for achieving heat exchange. Their special corrugated structure can increase the turbulence of the fluid, greatly enhance the heat transfer effect between the fluid and the plates 3, and significantly improve the overall heat exchange efficiency of the heat exchanger.

[0034] A fixed post 5 is fixedly connected to the outside of pipe 2. The fixed post 5 provides a foundation for the installation and positioning of the sealing shell 7. Its internal structure cooperates with the sealing shell 7 to ensure the accuracy and stability of the sealing connection process. The fixed post 5 has multiple slots inside, which match the limiting block 8 on the outside of the sealing shell 7. Through the engagement of the two, the initial positioning of the sealing shell 7 is achieved, laying the foundation for subsequent sealing operations. The sealing shell 7 is slidably connected inside the fixed post 5. The sliding design of the sealing shell 7 within the fixed post 5 makes the connection process between pipe 2 and transmission pipe more convenient, enabling the connection between the two to be achieved quickly and improving installation efficiency.

[0035] Multiple springs 9 are fixedly connected inside the sealing shell 7. Springs 9 play a key role in the sealing process. When the sealing shell 7 slides into the fixed column 5, the springs 9 are compressed and undergo elastic deformation, storing elastic potential energy to provide pre-tightening force for subsequent sealing. Multiple limiting blocks 8 are fixedly connected to the outside of the sealing shell 7. The limiting blocks 8 cooperate with the slots inside the fixed column 5. After the sealing shell 7 slides into place, the limiting blocks 8 are locked into the slots by rotating the sealing shell 7, thereby achieving circumferential fixation of the sealing shell 7 and preventing it from rotating or displacing during operation.

[0036] A sealing ring 10 is slidably connected inside the sealing shell 7. Under the action of spring 9, the sealing ring 10 can fit tightly against the connection between the pipe 2 and the transmission pipe, effectively preventing fluid leakage and ensuring the reliability of the seal. The other ends of multiple springs 9 are fixedly connected inside the sealing ring 10. Through the elastic restoring force of the springs 9, the sealing ring 10 is pushed outward, making the connection between the extrusion block 6 and the slot tighter, further enhancing the sealing effect. An extrusion block 6 is fixedly connected inside the fixing column 5. The extrusion block 6 cooperates with the sealing ring 10 and applies pressure to the sealing ring 10 during the sealing process, prompting it to better fill the gap and improve the sealing performance. The outer side of the sealing ring 10 is slidably connected to the outer side of the extrusion block 6. This sliding connection method allows the sealing ring 10 to flexibly adjust its position when subjected to pressure, ensuring the uniformity and integrity of the seal.

[0037] Reference Figure 1 , Figure 2 and Figure 4 The bottom of the connecting plate 1 has two limiting components that are slidably connected. The limiting components are used to assist in fixing and positioning the connecting plate 1, enhance the overall stability of the equipment, and prevent the connecting plate 1 from shifting due to vibration or other factors during operation. The two limiting components include a sliding shell 11, which is the main part of the limiting components. During installation and disassembly, the sliding shell 11 can slide inside the connecting plate 1 and the bracket 4 to achieve quick positioning and fixing.

[0038] The outer side of the sliding shell 11 is slidably connected to a limiting post 17, which provides guidance and limit for the sliding shell 11, ensuring that the sliding shell 11 maintains the correct direction and position during sliding and avoiding deviation. The outer side of the sliding shell 11 is slidably connected to the inside of the connecting plate 1. This design allows the sliding shell 11 to fit tightly with the connecting plate 1, providing reliable support and fixing force when fixing the connecting plate 1. The inner side of the sliding shell 11 is slidably connected to a sliding rod 12, which controls the extension and retraction of the limiting block 14 through sliding operation, realizing the quick installation and disassembly of the connecting plate 1.

[0039] A spring 16 is fixedly connected to the top of the sliding rod 12. When the sliding rod 12 is not subjected to external force, the spring 16 maintains its initial position and provides a restoring force to the sliding rod 12, ensuring that the limiting block 14 can be stably extended or retracted. The other end of the spring 16 is fixedly connected to the inside of the sliding shell 11, forming an elastic connection with the sliding rod 12, ensuring the operational flexibility and stability of the sliding rod 12. A spring 15 is fixedly connected to the outside of the sliding rod 12. The spring 15 deforms and stores energy when the limiting block 14 is squeezed into the sliding shell 11. When the limiting block 14 reaches the appropriate position, it releases energy to pop it out.

[0040] The other end of spring 15 is fixedly connected to the inside of limiting block 14. Through the elastic force of spring 15, limiting block 14 can be tightly pressed against the limiting groove of limiting post 17 to achieve a firm fixation of connecting plate 1. Multiple limiting blocks 14 are rotatably connected to the outside of sliding rod 12. Under the drive of sliding rod 12, limiting block 14 can flexibly extend, retract and rotate to adapt to different installation and disassembly requirements. The outside of limiting block 14 is slidably connected to the inside of limiting post 17. When sliding shell 11 slides into the inside of limiting post 17, limiting block 14 is squeezed into sliding shell 11. When it reaches the limiting groove position, it pops out and is locked into the limiting groove under the action of spring 15 to complete the fixation of connecting plate 1. A limiting ring 13 is fixedly connected to the outside of sliding shell 11. The limiting ring 13 plays the role of auxiliary positioning and strengthening fixation, further enhancing the connection stability between sliding shell 11 and connecting plate 1 and bracket 4, and preventing sliding shell 11 from loosening during operation.

[0041] Working principle: When the operator needs to transfer liquid into the pipe 2, the sealing shell 7 is placed inside the fixed column 5. Multiple limiting blocks 8 are located on the outside of the sealing shell 7, and a slot is opened inside the fixed column 5. The limiting blocks 8 slide into the slot. A squeezing block 6 is connected inside the fixed column 5. When the sealing shell 7 slides into the fixed column 5, the squeezing block 6 squeezes the sealing ring 10. Multiple springs 9 are connected inside the sealing ring 10. The springs 9 are squeezed by the sealing ring 10. The sealing shell 7 needs to be rotated so that the limiting blocks 8 rotate into the slot of the fixed column 5. Then, the sealing shell 7 is released, and the springs 9 push the sealing ring 10 outwards, making the squeezing block 6 more tightly connected inside the slot. Because a transfer pipe is fixed inside the sealing shell 7, liquid can be transferred into the pipe 2. When the transfer pipe needs to be removed, the sealing shell 7 can be rotated so that the limiting blocks 8 disengage from the slot, and the sealing shell 7 can be removed from inside the fixed column 5.

[0042] When working on plate 3, the limiting post 17 can be fixed in the designated position first. Then, the sliding shell 11 is slid into the interior of the connecting plate 1 and the bracket 4. After the sliding shell 11 slides into the interior of the limiting post 17, multiple limiting blocks 14 will be pressed into the interior of the sliding shell 11 by the inner wall of the limiting post 17. The limiting post 17 has a limiting groove inside. When the limiting block 14 slides to the outside of the limiting groove, the pressed limiting block 14 will be pushed out of the interior of the sliding shell 11 by the spring 15, so that the limiting block 14 abuts against the limiting groove. Inside the groove, the connecting plate 1 can be fixed in the designated position by the cooperation of the limiting ring 13 and the limiting block 14. When it is necessary to remove the connecting plate 1, the sliding rod 12 can be pressed into the sliding shell 11. The multiple limiting blocks 14 rotate on the outside of the sliding rod 12. So when the sliding rod 12 is squeezed, the limiting blocks 14 will be squeezed into the interior of the sliding shell 11 through the sliding shell 11. At this time, the limiting blocks 14 can be removed from the inside of the limiting groove, and the connecting plate 1 can be removed.

[0043] 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.
