It can meet process temperature requirements or achieve rational energy utilization by exchanging and transferring gas heat.

[0003] In existing gasification heat exchange devices, heat exchange fins are typically multi-layered stacked structures, relying on gas exchange pipes to exchange heat with the external medium. However, after prolonged use, dirt easily accumulates on the surface of the heat exchange fins, affecting heat exchange efficiency. Existing devices lack convenient structures for separating and repositioning the heat exchange fins. When cleaning or repairing the heat exchange fins, it is often necessary to disassemble a large number of connecting parts, which is cumbersome, time-consuming, and results in high downtime maintenance costs. Furthermore, it is difficult to efficiently remove dirt from the surface of the heat exchange fins, failing to ensure continuous and stable heat exchange while conveniently achieving self-cleaning and maintenance operations, thus limiting the heat exchange efficiency and maintenance convenience of the device.

[0004] Therefore, a high-efficiency gasification heat exchanger with self-cleaning function is proposed to address the above problems. Utility Model Content

[0010] 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.

[0011] Reference Figures 1 to 4This utility model provides an embodiment of a high-efficiency vaporization heat exchange device with self-cleaning function, including a support frame 1, which serves as the basic support structure for the entire device. It provides an installation carrier and spatial positioning for all internal components such as the air exchange pipes 2, heat exchange plates 3, electric push rods 4, and motor 18, ensuring orderly assembly of each component and maintaining the stability of the overall device structure. It forms the framework for the normal operation of the device. The support frame 1 has multiple air exchange pipes 2 inside, used to transport the gas medium to be heat exchanged. Multiple layers of heat exchange plates 3 are assembled on the outside of the air exchange pipes 2. During the flow of gas within the air exchange pipes 2, heat exchange occurs between the gas and the heat exchange plates 3 through the pipe wall, achieving vaporization heat exchange. This is the core channel for heat transfer. Multiple heat exchange plates 3 are arranged in multiple layers outside the air exchange pipes 2, increasing the contact area with the air exchange pipes 2 and the external environment, thus improving heat exchange efficiency. Relying on their own thermal conductivity, they transfer heat from the gas inside the air exchange pipes 2 or absorb heat from the outside and transfer it to the gas, making them key heat exchange components for vaporization heat exchange.

[0012] Two electric push rods 4 are installed on the right end of the inner wall of the support frame 1. After receiving self-cleaning or maintenance commands, they extend or retract to drive the cross plate 5 to move horizontally, providing power for the movement of the locking mechanism, thereby realizing the separation and resetting operation of the heat exchanger 3. They are the power source for controlling the separation and resetting operation of the heat exchanger 3. The output ends of the two electric push rods 4 are fixedly connected to the cross plate 5, connecting the output ends of the electric push rods 4 to the locking mechanism, playing the role of force transmission and structural connection. The linear motion of the electric push rods 4 is transmitted to the locking mechanism, driving the locking mechanism to move synchronously, so as to realize the separation and resetting operation of the heat exchanger 3. The right end of the cross plate 5 is provided with a locking mechanism consisting of multiple limit sleeves 6 connected in series. The locking mechanism provides installation space and motion guidance for internal components such as sliding rods 7, springs 8, and conical blocks 9. At the same time, multiple limit sleeves 6 are connected in series through the external connecting plate 11 to maintain the integrity of the locking mechanism and ensure the stable execution of the separation and resetting operation of the heat exchanger 3.

[0013] The outer side of the conical block 9 is slidably connected to the inside of the limiting sleeve 6. The outer side of the sliding block 10 is slidably connected to the inside of the limiting sleeve 6. The outer side of the connecting plate 11 is slidably connected to the inside of the limiting sleeve 6. Multiple limiting sleeves 6 are connected in series with the connecting plate 11. The outer side of the limiting block 12 is slidably connected to the outside of the limiting sleeve 6. A sliding rod 7 is provided inside the limiting sleeve 6 to provide support and guidance for the sliding of the conical block 9, ensuring that the conical block 9 moves stably inside the limiting sleeve 6 and preventing the conical block 9 from deviating. This ensures the accuracy of the locking mechanism in separating and resetting the heat exchanger 3. A spring 8 is sleeved on the outside of the sliding rod 7. Outside the sliding rod 7, the conical block 9 is provided with elastic buffer. When the conical block 9 slides inside the limiting sleeve 6, the spring 8 can absorb and buffer the impact force generated by the movement, and at the same time assist the conical block 9 to reset, ensuring the smooth operation of the locking mechanism. One end of the spring 8 is fixedly connected to the inside of the limiting sleeve 6, and the other end of the spring 8 is fixedly connected to the outside of the conical block 9. The conical block 9 is slidably connected to the outside of the sliding rod 7. During the movement of the locking mechanism, it gradually embeds into the gap of the heat exchange plate 3 with the help of its own conical structure. Through the squeezing and locking action, the separation of the multi-layer stacked heat exchange plate 3 is realized, creating space for cleaning and maintenance.

[0014] Simultaneously, during device reset, it works with other components to re-adhere the heat exchange plates 3. Sliding blocks 10 are fixedly connected to both the top and bottom ends of the conical block 9, sliding along the inner wall of the limiting sleeve 6. This provides auxiliary guidance for the sliding of the conical block 9, further ensuring the stability of its movement within the limiting sleeve 6. This makes the separation and engagement of the conical block 9 with respect to the heat exchange plates 3 more reliable. A connecting plate 11 is provided on the outside of the limiting sleeve 6, assembled thereon, for connecting multiple limiting sleeves 6 in series. The individual limiting sleeves 6 are connected into a whole locking mechanism to ensure that when the electric push rod 4 drives the cross plate 5 to move, multiple limiting sleeves 6 move synchronously, maintaining the consistency of the locking mechanism's separation and resetting operation of the heat exchange plate 3. The connecting plate 11 is provided with a limiting block 12 on the outside of the limiting sleeve 6, which slides on the outside of the limiting sleeve 6 to limit the connecting plate 11, prevent the connecting plate 11 from sliding excessively outside the limiting sleeve 6, ensure the stability of the overall structure of the locking mechanism, and enable the locking mechanism to stably perform the operation on the heat exchange plate 3. Reference Figures 1 to 4Multiple telescopic rods 13 are fixedly connected to the left end of the inner wall of the support frame 1. Their telescopic nature, combined with spring 14, provides elastic support and displacement compensation for the top block 15 during the device reset process, assisting the locking mechanism in smooth return to its original position and maintaining the stability of the internal structure of the device. Spring 14 is sleeved on the outside of the telescopic rods 13, providing elastic buffering for the top block 15. During the reset of the locking mechanism, its elasticity helps the top block 15 buffer the locking mechanism, making the reset more stable. Simultaneously, during device operation, it can... To absorb some vibration and ensure the stability of the device structure, a top block 15 is fixedly connected to the right end of every two springs 14. The top block 15 is connected to the right end of the spring 14 and contacts the outside of the leftmost limiting sleeve 6. During the device reset process, the elastic buffer of the spring 14 helps the locking mechanism to return to its position smoothly. It plays a positioning and buffering role in the reset of the locking mechanism, ensuring that the heat exchange plate 3 is accurately reset and fitted. The right end of the top block 15 contacts the outside of the leftmost limiting sleeve 6. One end of the spring 14 is fixedly connected to the left end of the inner wall of the support frame 1, and the other end of the spring 14 is fixedly connected to the left end of the top block 15. Reference Figures 2 to 5Two fixing blocks 16 are fixedly connected to the right end of the inner wall of the support frame 1. These blocks provide rotational support for the bidirectional threaded rod 17, ensuring its stable rotation. This forms the structural basis for the motor 18 to drive the bidirectional threaded rod 17, threaded sleeve 19, and other components. The bidirectional threaded rod 17 is rotatably connected inside the two fixing blocks 16 and connected to the output end of the motor 18. Driven by the motor 18, it rotates, and through its own threaded structure, drives the two threaded sleeves 19 to move in opposite directions or away from each other, thereby adjusting the position of the clamping plate 20. This provides the prerequisite for adjusting the position of the conical block 9 in the positioning mechanism. The front end of the bidirectional threaded rod 17 is fixedly connected to the motor 18, which serves as the power source, driving the bidirectional threaded rod 17 to rotate. Through threaded transmission, it realizes the movement of the threaded sleeve 19 and the clamping plate 20, thereby adjusting the position of the sliding block 10 and the conical block 9, facilitating the subsequent heat exchange fins. The mechanical structure preparation before operation is a key component that triggers the initial action of the locking mechanism. The external threaded rod 17 has two threaded sleeves 19 that are threadedly connected to it. When the double-threaded rod 17 rotates, the sleeves 19 move in opposite directions or in opposite directions along it, synchronously driving the externally fixed clamping plate 20 to move, thereby pressing the sliding block 10 and adjusting the position of the conical block 9. The external fixed connection of the clamping plate 20 to the threaded sleeve 19 is fixed to the outside of the threaded sleeve 19 and slides on the outside of multiple limiting sleeves 6. It moves under the drive of the threaded sleeve 19 and adjusts the position of the conical block 9 in the limiting sleeve 6 by contacting and pressing with multiple sliding blocks 10, so that the conical block 9 of the locking mechanism is in a state of linkage operation, preparing for the separation of the heat exchange plate 3. The external sliding connection of the clamping plate 20 to the outside of multiple limiting sleeves 6 is such that the outside of the clamping plate 20 is in contact with the outside of multiple sliding blocks 10.

[0015] Working principle: The device uses a support frame 1 as the overall support frame, with multiple air exchange pipes 2 pre-arranged inside. The air exchange pipes 2 are equipped with multiple layers of heat exchange plates 3, forming a core structure for gasification heat exchange. At the same time, two electric push rods 4 are installed on the right end of the inner wall of the support frame 1, and the output end is connected to a cross plate 5; multiple sets of telescopic rods 13 are fixed on the left end of the inner wall, and springs 14 are sleeved on the outside of them. The right end of every two sets of springs 14 is connected to a top block 15; two fixing blocks 16 are provided on the right end of the inner wall, and bidirectional threaded rods 17 are rotatably connected inside. The front end of the threaded rod is connected to a motor 18, and two threaded sleeves 19 are threadedly engaged on the outside. A clamping plate 20 is fixed on the outside of the threaded sleeves 19. The right end of the cross plate 5 is connected to a locking mechanism consisting of multiple limit sleeves 6 connected in series. The limit sleeve 6 is equipped with a sliding rod 7 and a spring 8. A conical block 9 is slidably connected to the sliding rod 7. Sliding blocks 10 are fixed at the top and bottom ends of the conical block 9. The limit sleeve 6 is equipped with a connecting plate 11 and a limit block 12. All components are in the initial assembly state ready to be triggered, waiting for self-cleaning or maintenance instructions.

[0016] When heat exchanger 3 needs to be separated for cleaning and maintenance, motor 18 is started. Motor 18 drives the bidirectional threaded rod 17 to rotate. Because the bidirectional threaded rod 17 is threadedly connected to the two threaded sleeves 19, during rotation, the two threaded sleeves 19 move towards or away from each other along the bidirectional threaded rod 17. The threaded sleeves 19 synchronously drive the externally fixed clamping plate 20 to move. The clamping plate 20 is slidably sleeved on the outside of multiple limiting sleeves 6, and during movement, it contacts multiple sliding blocks 10. By pressing the sliding blocks 10, the position of the conical block 9 within the limiting sleeve 6 is adjusted, so that the conical block 9 of the clamping mechanism is in a state of interlocking operation, preparing the mechanical structure for subsequent separation of heat exchanger 3.

[0017] The electric push rod 4 extends or retracts, and its output end drives the cross plate 5 to move horizontally. The locking mechanism of the series limiting sleeve 6 connected to the right end of the cross plate 5 moves together. Inside the limiting sleeve 6, the sliding rod 7 provides support and guidance for the conical block 9, and the spring 8 provides elastic cushioning for the conical block 9. The conical block 9 can slide inside the limiting sleeve 6, and the sliding blocks 10 at its top and bottom slide on the inner wall of the limiting sleeve 6 to ensure the stability of the conical block 9's movement. Outside the limiting sleeve 6, the connecting plate 11 connects multiple limiting sleeves 6 in series to maintain the integrity of the locking mechanism. The limiting block 12 is slidably connected to the outside of the limiting sleeve 6 to limit the connecting plate 11. As the cross plate 5 moves, the locking mechanism, with the help of the mechanical linkage of the conical block 9 and other components, gradually embeds itself into the gaps between the heat exchange plates 3. Through squeezing, locking and other actions, it gradually separates the multi-layered stacked heat exchange plates 3, creating gaps between the originally tightly fitted heat exchange plates 3, creating space for cleaning and maintenance.

[0018] During the separation of heat exchanger plate 3, the electric push rod 4 drives the cross plate 5 and the locking mechanism to move and adjust their positions continuously in small increments. The slight shaking generated by this movement causes the dirt adhering to the surface of the heat exchanger plate 3 to fall off due to vibration. Simultaneously, the separated heat exchanger plate 3 is in a dispersed state, allowing staff to directly observe the cleanliness of its surface and whether there is any damage. If deep cleaning is required, residual dirt can be removed manually. If damage is found in the heat exchanger plate 3, individual or partial heat exchanger plates 3 can be directly inspected or replaced. During this process, the gas exchange pipe 2 maintains basic gas transmission, minimizing the continuous impact on the vaporization heat exchange function.

[0019] After cleaning and maintenance, the electric push rod 4 reverses its movement, causing the cross plate 5 and the locking mechanism to retract, allowing the heat exchange plates 3 to reposition and re-fit, restoring the multi-layered stacked heat exchange structure. The motor 18 rotates in the opposite direction, driving the bidirectional threaded rod 17 to reverse, returning the two threaded sleeves 19 and the clamping plate 20 to their initial positions, preparing for the next self-cleaning and maintenance. During the repositioning process, the telescopic rod 13, spring 14, and top block 15, with the elastic cushioning of spring 14, assist the locking mechanism in smoothly returning to its original position, maintaining the stability of the internal structure of the device. Afterwards, the device, with the restored heat exchange plates 3 and the air exchange pipe 2 as its core, continuously performs vaporization heat exchange operations, periodically or as needed, triggering the above process to ensure long-term efficient operation of the device, balancing heat exchange function with self-cleaning and maintenance requirements, and ensuring both heat exchange efficiency and ease of equipment maintenance.

[0020] 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.
