Description

Technical Field

[0001] This utility model relates to the field of heat pipe heat exchanger technology, and in particular to a ash removal and anti-clogging structure for heat pipe heat exchangers. Background Technology

[0002] Against the backdrop of accelerated global energy structure transformation and the continuous advancement of energy conservation and emission reduction policies, high-efficiency heat exchange technology has become a key breakthrough for reducing energy consumption and improving energy efficiency in the industrial sector. Heat pipe heat exchangers, with their high heat transfer performance, flexible arrangement, and wide applicability, play an important role in industries such as chemical, power, and metallurgy, providing strong support for achieving cascaded and circular energy utilization.

[0003] A heat pipe heat exchanger mainly consists of a shell, a heat pipe bundle, and a baffle structure. The heat pipe typically includes a shell, a wick, and a working medium. When the hot fluid flows through the evaporation section of the heat pipe, the working medium absorbs heat and vaporizes. The vapor flows to the condensation section under the action of the pressure difference, where it releases heat and condenses into a liquid upon encountering the cold fluid. The liquid then flows back to the evaporation section under the capillary force of the wick. This cycle repeats continuously. Heat transfer between the hot and cold fluids is achieved through the phase change heat transfer of the working medium inside the heat pipe. The baffle separates different fluid channels, while the shell provides support and protection for the overall structure.

[0004] In the prior art, some equipment filters the heat medium before it enters the pipeline during the heat conversion process to remove impurities and ensure stable operation of the equipment. However, as the usage time increases, the filter plate will inevitably be blocked by various impurities. The blockage of the filter plate will reduce the flow efficiency of the heat medium and affect the overall heat exchange performance of the heat exchanger. To address this issue, a dust removal and anti-blocking structure for heat pipe heat exchangers is proposed. Utility Model Content

[0037] 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.

[0038] Reference Figures 1 to 3 This utility model provides an embodiment of a heat pipe heat exchanger ash removal and anti-clogging structure, including a tank 1. The tank 1 is the basic support and heat exchange space carrier of the entire heat pipe heat exchanger. A heat medium inlet pipe 2 is fixedly connected to the top left side of the tank 1. The heat medium inlet pipe 2 serves as the channel for the heat medium to enter the heat exchanger. An anti-clogging mechanism is provided inside the heat medium inlet pipe 2. A funnel 12 is slidably connected to the top of the heat medium inlet pipe 2. The funnel 12 is used to receive the externally transported heat medium, expand the receiving area of ​​the heat medium entering the inlet pipe, facilitate the introduction of the medium, and cooperate with the installation mechanism to achieve quick assembly and disassembly. It is convenient to clean the residual impurities inside the heat medium inlet pipe 2 and maintain the anti-clogging mechanism. An installation mechanism is fixedly connected to the outside of the heat medium inlet pipe 2.

[0039] The anti-blocking mechanism includes a rotating rod 3, which transmits the rotation of the connecting plate 4 to the disc 5, thus transmitting force. The rotating rod 3 is externally rotatably connected to the inside of the heat medium inlet pipe 2, and the connecting plate 4 is fixedly connected to the outside of the rotating rod 3. When the heat medium enters the heat medium inlet pipe 2, the flow of the heat medium drives the connecting plate 4 to rotate, which in turn drives the disc 5 to rotate via the rotating rod 3. The disc 5 is fixedly connected to the outside of the rotating rod 3, and the disc 5 can convert the circumferential rotation of the rotating rod 3 into the reciprocating motion of the connecting rod 6. The connecting rod 6 is rotatably connected inside the disc 5, and the connecting rod 6 converts the circumferential motion of the disc 5 into the reciprocating motion of the connecting rod 6. The reciprocating motion of the slide plate 7 is transformed into its own reciprocating motion, which in turn drives the slide plate 7 to make linear reciprocating motion along the guide rod 8. The guide rod 8 is fixedly connected to the outside of the heat medium inlet pipe 2. The guide rod 8 provides linear motion guidance for the slide plate 7. The slide plate 7 is slidably connected to the outside of the guide rod 8. The slide plate 7 is used to drive the push assembly. The internal rotation of the connecting rod 6 is rotatably connected to the outside of the slide plate 7. The push assembly is fixedly connected to the outside of the slide plate 7. The filter plate 11 is fixedly connected to the inner wall of the heat medium inlet pipe 2. The filter plate 11 is used to filter larger particulate impurities in the heat medium, reduce the entry of pollutants into the heat exchange area inside the tank 1, and reduce the risk of heat exchange tube blockage.

[0040] The pushing component includes a push rod 9, which converts the linear reciprocating motion of the slide plate 7 into the synchronous motion of the scraper 10, playing the role of force transmission and motion extension. One external end of the push rod 9 is fixedly connected to the outer side of the slide plate 7, and the other external end of the push rod 9 is fixedly connected to the scraper 10. The scraper 10 reciprocates with the push rod 9 and scrapes off the impurities attached to the filter plate 11 by relative sliding with the surface of the filter plate 11, preventing the filter plate 11 from being blocked and affecting the flow of heat medium and heat exchange efficiency. The bottom of the scraper 10 is slidably connected to the top of the filter plate 11.

[0041] Reference Figure 4 and Figure 5 The installation mechanism includes a support 13, which provides the installation foundation for the sliding clamp 15, push plate 14, and elastic component, and is the frame structure of the installation mechanism. The support 13 is externally fixedly connected to the outside of the heat medium inlet pipe 2. The push plate 14 is slidably connected inside the support 13. The push plate 14 drives the sliding clamp 15 to move closer to and away from the limiting post 16 through its own movement, realizing the clamping and releasing action of the limiting post 16 of the funnel 12. The sliding clamp 15 is externally fixedly connected to the push plate 14. The sliding clamp 15 is slidably connected to the inside of the limiting post 16, realizing the limiting and fixing of the funnel 12. The sliding clamp 15 is externally slidably connected to the inside of the support 13. The limiting post 16 is externally fixedly connected to the funnel 12. The groove of the limiting post 16 cooperates with the sliding clamp 15 and is the key component for the installation and positioning of the funnel 12. The elastic component is internally fixedly connected to the support 13. The sliding clamp 15 is externally slidably connected to the inside of the limiting post 16.

[0042] The elastic component includes a round rod 17, which provides installation guidance and movement limit for the spring 18, ensuring that the spring 18 can only extend and retract along the axis of the round rod 17. This ensures that the elastic force applied by the elastic component to the sliding clamp 15 is stable and maintains the reliability of the cooperation between the sliding clamp 15 and the limiting post 16. The outer part of the round rod 17 is fixedly connected to the inside of the support 13, and the outer part of the round rod 17 is fitted with the spring 18. The spring 18 uses the elastic force generated by its own elastic deformation to push the sliding clamp 15 to move towards the limiting post 16, thereby clamping and fixing the limiting post 16. One outer end of the spring 18 is fixedly connected to the outside of the sliding clamp 15, and the other outer end of the spring 18 is fixedly connected to the outer inner side of the support 13.

[0043] Reference Figure 1 and Figure 2 A cold medium outlet pipe 19 is fixedly connected to the top side of the tank body 1. The cold medium outlet pipe 19 serves as the channel for the cold medium to flow out of the tank body 1 after completing heat exchange with the hot medium. A hot medium outlet pipe 20 is fixedly connected to the bottom side of the tank body 1. The hot medium outlet pipe 20 is used to discharge the hot medium after heat exchange and cooling in the tank body 1. A cold medium inlet pipe 21 is fixedly connected to the bottom side of the tank body 1. The cold medium inlet pipe 21 is the channel for the cold medium to enter the tank body 1 to participate in heat exchange. A head baffle 22 is fixedly connected to the left side of the tank body 1. The head baffle 22 serves to separate the internal space of the tank body 1 and guide the flow direction of the medium. A transverse baffle 24 is fixedly connected to the inside of the tank body 1. The horizontal partition 24 allows the medium to flow more evenly through the heat exchange tubes, improving heat exchange efficiency. A vertical partition 23 is fixedly connected to the side of the horizontal partition 24 and the end cap partition 22. The vertical partition 23 is an important support for the heat exchange tubes and a space-separating component of the tank 1. The outside of the vertical partition 23 is fixedly connected to the inside of the tank 1. Two U-shaped heat exchange tubes 25 are fixedly connected inside the vertical partition 23. The U-shaped heat exchange tubes 25 are the core functional components for realizing the heat exchange of hot and cold media. A baffle 26 is provided inside the tank 1. The main function of the baffle 26 is to change the flow direction of hot and cold media. The outside of the two U-shaped heat exchange tubes 25 is fixedly connected to the inside of the baffle 26.

[0044] Working principle: The hot medium is first received by the funnel 12 and flows into the hot medium inlet pipe 2. The flow of the hot medium drives the connecting plate 4 to rotate. The connecting plate 4 causes the disc 5 to rotate via the rotating rod 3. The disc 5 drives the slide plate 7 to make linear reciprocating motion along the guide rod 8 via the connecting rod 6. When the slide plate 7 moves, it drives the push rod 9. The push rod 9 then drives the scraper 10 to slide on the top of the filter plate 11 to scrape off impurities on the filter plate 11 and prevent clogging.

[0045] The filtered hot medium enters tank 1. Inside tank 1, the cold medium enters through the cold medium inlet pipe 21. The hot and cold media flow in the channel constructed by the end plate 22, the horizontal baffle 24, and the vertical baffle 23, exchanging heat with the help of the U-shaped heat exchange tube 25. The baffle plate 26 changes the flow direction of the medium to enhance heat exchange. After heat exchange is completed, the hot medium is discharged from the hot medium outlet pipe 20, and the cold medium is discharged from the cold medium outlet pipe 19. In the installation mechanism, pulling the push plate 14 drives the sliding clamp 15 to move, causing the limiting post 16 to disengage from the limitation of the sliding clamp 15. At the same time, the spring 18 contracts, which can then remove the funnel 12 from the top of the hot medium inlet pipe 2. When the push plate 14 is released, the spring 18 returns to its original deformation and generates elastic force. The elastic force pushes the sliding clamp 15 to clamp the limiting post 16 of the funnel 12, realizing the quick installation and removal of the funnel 12, which is convenient for equipment maintenance.

[0046] 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.
