Description

Technical Field

[0001] This invention relates to the field of heat exchange technology, and more particularly to a spiral plate heat exchanger with a divided cylindrical cavity. Background Technology

[0002] Heat exchangers are core heat exchange equipment in the continuous sterilization process of materials in fields such as bio-fermentation, food processing, biopharmaceuticals and beverage production. They are mainly used for rapid heating, high-temperature maintenance and cooling of materials to be sterilized. Their heat exchange efficiency and temperature uniformity directly determine the sterilization effect and the retention rate of heat-sensitive components.

[0003] Currently, many types of heat exchangers still have numerous shortcomings and deficiencies in practical applications. Common plate heat exchangers, with their narrow flow channel cross-sections, are prone to clogging when conveying materials containing impurities or high viscosity, affecting the stable operation of the equipment. Furthermore, traditional heat exchangers mostly adopt a single-pass flow design, limiting the flow path of hot and cold fluids within the heat exchanger. This severely restricts the contact area between the hot and cold fluids, resulting in low heat transfer efficiency and an inability to achieve efficient heat exchange within a limited space, further reducing the overall heat exchange efficiency. At the same time, the flow channel structure of traditional heat exchangers presents a dilemma: if the flow channel structure is complex, it is prone to material residue and difficult to thoroughly clean, easily leading to material contamination; if the flow channel structure is too simple, it cannot form effective disturbance, resulting in poor heat exchange performance. It is difficult to balance cleanliness and heat exchange efficiency, making it unsuitable for diverse industrial production scenarios. Therefore, these shortcomings fail to meet user needs, necessitating further improvements.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a spiral plate heat exchanger with a divided cylinder, in order to achieve a more practical purpose. Summary of the Invention

[0005] The purpose of this invention is to solve the technical problems of existing heat exchangers, such as easy clogging of the flow channels, low heat exchange efficiency, and difficulty in balancing cleanliness and heat exchange efficiency to adapt to diverse industrial production scenarios.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A spiral plate heat exchanger with a divided cylinder includes a heat exchanger body, two sets of spiral plates disposed inside the heat exchanger body and spirally wound together, and a divided cylinder coaxially embedded in the cavity enclosed by the two sets of spiral plates. The inner cavity of the split-cavity cylinder is fixedly provided with a split-cavity rubber plate. The inner cavity of the split-cavity cylinder is sealed and divided into independent hot material flow channels and cold material flow channels by the split-cavity rubber plate. The side wall of the split-cavity cylinder is provided with two sets of opening slots, which are respectively connected to the hot material flow channel and the cold material flow channel, so as to realize the connection between the internal flow channel and the outer spiral flow channel. The cavity cylinder is equipped with two sets of adjustment mechanisms, which are respectively installed inside the hot material flow channel and the cold material flow channel. Each adjustment mechanism includes an adjustment component fixedly installed inside the cavity cylinder. A linkage component is linked to the inner side of the adjustment component. One side of the linkage component is fixedly connected to the cavity rubber plate. By externally driving the adjustment component to move, the linkage component can be synchronously driven and the cavity rubber plate can undergo controllable elastic deformation, changing the cross-sectional shape of the flow channel and forming a curved disturbance heat exchange flow channel.

[0007] As a further description of the above technical solution: The upper and lower ends of the heat exchanger body are respectively fixedly and sealed with an upper cover plate and a lower cover plate. The upper cover plate is provided with a hot material inlet, and the lower cover plate is provided with a cold material inlet. The left shell of the heat exchanger body is provided with a hot material outlet, and the right shell is provided with a cold material outlet. Each pipe is connected to the internal flow channel of the heat exchanger body.

[0008] As a further description of the above technical solution: Both the upper and lower cover plates are fixedly fitted with spiral sealing rings on their inner sides, and the spiral sealing rings are respectively sealed and fitted to the two ends of two sets of spiral plates that are spirally wound together.

[0009] As a further description of the above technical solution: The cavity rubber plate is made of silicone rubber.

[0010] As a further description of the above technical solution: Several spacer posts are fixedly mounted on the sidewalls of the spiral plates. The spacer posts are evenly distributed along the spiral plate winding direction and are used to limit the width of the flow channel after the two sets of spiral plates are spirally wound.

[0011] As a further description of the above technical solution: The adjustment assembly includes an adjustment column fixedly disposed in the inner cavity of the cavity cylinder. One end of the adjustment column penetrates the top wall of the cavity cylinder and extends to the outside. An adjustment screw is coaxially rotatably installed inside the adjustment column. A telescopic rod is fixedly installed at one end of the adjustment screw. The telescopic end of the telescopic rod extends outward to the outside of the adjustment column, and an adjustment component is fixedly connected to the end of the telescopic end. An adjustment block is threadedly engaged with the adjustment screw on its outer periphery.

[0012] As a further description of the above technical solution: A limiting slider is fixedly installed on the outer wall of the adjusting block, and a limiting groove is opened on the inner wall of the adjusting column, with the limiting slider located in the limiting groove.

[0013] As a further description of the above technical solution: The outer peripheral wall of the adjusting component is uniformly provided with several strip-shaped anti-slip grooves along the circumference.

[0014] As a further description of the above technical solution: The adjustment mechanism also includes a locking assembly, which includes a locking block fixed to one end of the adjustment column and a locking block fixedly assembled on the side of the adjustment member facing the locking block. The locking block has a locking groove adapted to the locking block on one end face of the adjustment member. The locking block and the locking groove are engaged and locked to position the adjustment member after adjustment.

[0015] As a further description of the above technical solution: The linkage component includes a sealing sleeve fixedly mounted on the adjusting column. A steel wire rope is threaded through the inner side of the sealing sleeve. One end of the steel wire rope extends into the adjusting column and is fixedly connected to the adjusting block. A fixing clip is fixedly installed at the other end of the steel wire rope. The fixing clip is fitted and fixedly mounted on the side wall of the cavity rubber plate.

[0016] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are: 1. This spiral plate heat exchanger with a segmented cylindrical cavity forms interlaced and spaced hot and cold material channels through the spiral plates winding around each other. This significantly extends the fluid flow path and increases the effective contact area between the hot and cold fluids, making heat exchange more thorough and uniform. At the same time, the setting of the spaced columns enhances the turbulence and disturbance of the fluid in the channel, thins the heat exchange boundary layer, and further improves the heat transfer efficiency between the hot and cold fluids. Furthermore, through the synergistic effect between the adjustment mechanism and the segmented rubber plate, the curved wave-like structure formed by the segmented rubber plate can actively change the flow path and flow state of the fluid, forcing the fluid to form continuous disturbance and backflow in the channel, fundamentally improving the problems of low heat exchange efficiency and uneven heat exchange in traditional channels.

[0017] 2. This spiral plate heat exchanger with a divided cylindrical cavity can restore the divided rubber plate to its initial vertical and flat state when cleaning is required, making the internal flow channel straight and smooth. This eliminates dead corners and grooves formed by the curved and wavy structure, allowing the cleaning water to flow through the entire flow channel area without obstruction or residue. This completely avoids dead corners and material accumulation areas that cannot be cleaned, greatly improving the cleaning effect and cleanliness. It achieves a dual balance of enhanced heat exchange and convenient cleaning, significantly extending the continuous operation cycle of the equipment and reducing maintenance difficulty and cost.

[0018] 3. This spiral plate heat exchanger with a divided cylindrical cavity uses a spacer column to stably limit the spacing between the spiral plates, preventing deformation, collapse, or channel closure of the spiral plates under high-pressure scouring and pressure during long-term use. This ensures the long-term stability of the channel cross-sectional dimensions, improving the reliability and service life of the equipment. Simultaneously, utilizing the locking and positioning function of the adjusting components, after the channel shape is adjusted to the correct position, the adjusting components, adjusting screw, and adjusting block can be quickly and reliably locked and fixed as a whole. This effectively prevents the adjusting position from shifting, loosening, or the divided rubber plates from automatically springing back to their original position during equipment operation, ensuring that the heat exchange effect and channel state remain stable and controllable, thus improving the safety and reliability of equipment operation.

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0023] Please see Figures 1 to 13A spiral plate heat exchanger with a divided cylinder includes a heat exchanger body 10, two sets of spiral plates 14 spirally wound together inside the heat exchanger body 10, and a divided cylinder 20 coaxially embedded in the cavity enclosed by the two sets of spiral plates 14. A divided rubber plate 21 is fixedly provided inside the divided cylinder 20, and the inner cavity of the divided cylinder 20 is sealed and divided into independent hot material flow channels 201 and cold material flow channels 202 by the divided rubber plate 21. Two sets of opening slots 22 are correspondingly opened on the side wall of the divided cylinder 20, and the two sets of opening slots 22 are respectively connected to the hot material flow channels 201 and the cold material flow channels 202 to achieve internal... The flow channel is connected to the outer spiral flow channel; two sets of adjustment mechanisms 30 are provided inside the cavity cylinder 20. The two sets of adjustment mechanisms 30 are respectively installed inside the hot material flow channel 201 and the cold material flow channel 202. The adjustment mechanism 30 includes an adjustment component 31 fixedly installed inside the cavity cylinder 20. A linkage component 33 is linked to the inner side of the adjustment component 31. One side of the linkage component 33 is fixedly connected to the cavity rubber plate 21. By externally driving the adjustment component 31 to move, the linkage component 33 can be synchronously driven and drive the cavity rubber plate 21 to undergo controllable elastic deformation, change the cross-sectional shape of the flow channel and form a curved disturbance heat exchange flow channel.

[0024] The spiral plates 14 are spirally wound together to form interlaced and spaced hot material channels 201 and cold material channels 202, which significantly prolongs the fluid flow path and increases the effective contact area between hot and cold fluids, making heat exchange more thorough and uniform. At the same time, the setting of the spacer column 141 enhances the turbulence disturbance of the fluid in the channel, thins the heat exchange boundary layer, and further improves the heat transfer efficiency between hot and cold fluids. Furthermore, through the synergistic effect between the adjustment mechanism 30 and the cavity rubber plate 21, the curved wave-like structure formed by the cavity rubber plate 21 can actively change the flow path and flow state of the fluid, forcing the fluid to form continuous disturbance and backflow in the channel, fundamentally improving the problems of low heat exchange efficiency and uneven heat exchange in traditional channels.

[0025] Please see Figures 1 to 2 The upper and lower ends of the heat exchanger body 10 are respectively fixedly and sealed with an upper cover plate 11 and a lower cover plate 12. The upper cover plate 11 is provided with a hot material inlet 101, and the lower cover plate 12 is provided with a cold material inlet 102. The left shell of the heat exchanger body 10 is provided with a hot material outlet 103, and the right shell is provided with a cold material outlet 104. Each pipe is connected to the internal flow channel of the heat exchanger body 10. The setting of the hot material inlet 101 and the cold material inlet 102 is conducive to the input of materials. When it is necessary to cool down the hot material, the external hot material pipeline can be connected to the hot material inlet 101 of the heat exchanger. When it is necessary to heat up the cold material, the external cold material pipeline can be connected to the cold material inlet 102 of the heat exchanger.

[0026] Please see Figure 2Both the upper cover plate 11 and the lower cover plate 12 are fixedly fitted with spiral sealing rings 13. The spiral sealing rings 13 are respectively sealed and fitted to both ends of two sets of spiral plates 14 that are spirally wound together. The sealing performance of the device can be improved by setting the spiral sealing rings 13.

[0027] Please see Figure 7 The cavity rubber plate 21 is made of silicone rubber. Since silicone rubber has excellent high temperature and low temperature resistance and can maintain elasticity in extreme hot and cold environments, its applicability is further improved by making the cavity rubber plate 21 of silicone rubber.

[0028] Please see Figures 4 to 5 Several spacer posts 141 are fixedly mounted on the side walls of the spiral plates 14. The spacer posts 141 are evenly distributed along the winding direction of the spiral plates 14 and are used to limit the width of the flow channel after the two sets of spiral plates 14 are spirally wound. By setting spacer posts 141 between the spiral plates 14, the spacing between the spiral plates 14 can be stably limited. This can prevent the spiral plates 14 from deforming, collapsing or closing the flow channel under the high pressure of the material during long-term use. At the same time, when the material flows in the spiral flow channel formed by the spiral plates 14, it will continuously contact, collide and flow around the spacer posts 141, thereby breaking the laminar flow state of the fluid, enhancing the turbulent disturbance of the fluid in the flow channel, thinning the heat exchange boundary layer, and making the heat transfer between the hot and cold fluids more rapid and sufficient.

[0029] Please see Figures 8 to 11 The adjusting assembly 31 includes an adjusting column 311 fixedly disposed within the inner cavity of the cavity cylinder 20. One end of the adjusting column 311 penetrates the top wall of the cavity cylinder 20 and extends to the outside. An adjusting screw 312 is coaxially rotatably mounted inside the adjusting column 311. A telescopic rod 313 is fixedly mounted at one end of the adjusting screw 312. The telescopic end of the telescopic rod 313 extends outward to the outside of the adjusting column 311, and an adjusting element 314 is fixedly connected to the telescopic end. An adjusting element 314 is threadedly fitted around the outer periphery of the adjusting screw 312. Block 315; by rotating the adjusting member 314, the adjusting member 314 rotates simultaneously, driving the telescopic rod 313 and the adjusting screw 312 to rotate synchronously. Since the telescopic rod 313 can only extend and retract and cannot rotate, the transmission can be guaranteed to be stable and reliable. As the adjusting member 314 rotates continuously, the adjusting block 315 and the adjusting screw 312 are screwed together. Under the limiting action of the limiting slider 3151 and the limiting groove 3111, the adjusting block 315 only moves along the axial direction of the adjusting screw 312 and does not rotate.

[0030] Please see Figures 9 to 11A limiting slider 3151 is fixedly installed on the outer wall of the adjusting block 315, and a limiting groove 3111 is opened on the inner wall of the adjusting column 311, with the limiting slider 3151 located in the limiting groove 3111. During the movement of the adjusting block 315, the limiting slider 3151 is driven to slide smoothly in the limiting groove 3111 on the inner wall of the adjusting column 311. This setting effectively ensures that the adjustment process is stable, accurate, and reliable, and there will be no slippage, offset, or rotation, thus improving the flow channel adjustment accuracy and operational stability.

[0031] Please see Figure 10 The outer peripheral wall of the adjusting component 314 is provided with several strip-shaped anti-slip grooves evenly distributed along the circumference; by providing anti-slip grooves on the outer peripheral wall of the adjusting component 314, it can play a role in preventing slipping during operation, and further improve its applicability.

[0032] Please see Figures 8 to 10 The adjustment mechanism 30 also includes a locking assembly 32, which includes a locking block 321 fixed to one end of the adjustment column 311 and a locking latch block 322 fixedly assembled on the side of the adjustment member 314 facing the locking block 321. The locking block 321 has a locking groove 323 adapted to the locking latch block 322 on one end face opposite to the adjustment member 314. The locking latch block 322 and the locking groove 323 are engaged to lock the adjustment member 314 after adjustment. After the adjustment member 314 is rotated and adjusted, the adjustment member 314 is pressed to lock the telescopic rod 3. 13 is squeezed to retract and reset the telescopic rod 313. At the same time, the adjusting component 314 drives the locking block 322 to re-embed and lock in the locking groove 323 of the locking block 321, thereby achieving the locking and positioning of the adjustment position. This setting can quickly and reliably lock and fix the adjusting component 314, adjusting screw 312 and adjusting block 315 as a whole after the flow channel shape is adjusted to the position. This effectively avoids the adjustment position from shifting, loosening or the automatic rebound and reset of the cavity rubber plate 21 due to fluid impact, vibration and other factors during equipment operation, and ensures that the bending wave shape of the flow channel remains stable for a long time.

[0033] Please see Figures 9 to 11The linkage component 33 includes a sealing sleeve 331 fixedly mounted on the adjusting column 311. A steel wire rope 332 passes through the inner side of the sealing sleeve 331. One end of the steel wire rope 332 extends into the adjusting column 311 and is fixedly connected to the adjusting block 315. A fixing strip 333 is fixedly installed at the other end of the steel wire rope 332. The fixing strip 333 is fitted and fixedly mounted on the side wall of the cavity rubber plate 21. When the adjusting block 315 moves, it pulls the steel wire rope 332 to move synchronously, and the other end of the steel wire rope 332 pulls the fixing strip 333. 3. The steel wire rope 332 is attached to the side wall of the cavity rubber plate 21. During the process of pulling the fixing strip 333, the cavity rubber plate 21 can be deformed synchronously, which can make the cavity rubber plate 21 form a continuous curved wave structure, thereby changing the flow channel shape and flow cross section inside the cavity cylinder 20. This can actively change the flow path and flow state of the fluid, force the fluid to form continuous disturbance and backflow in the flow channel, further enhance the turbulence effect, effectively break the laminar flow state, thin the heat exchange boundary layer, and make the heat exchange of hot and cold fluids more sufficient and uniform.

[0034] Working principle: This device can both cool down hot materials and heat up cold materials, and the two working modes can be switched freely according to the actual working conditions. When it is necessary to cool the hot material, firstly, the external hot material pipeline is connected to the hot material inlet 101 of the heat exchanger, and the cooling medium pipeline is connected to the cold material inlet 102. The hot material to be exchanged enters from the hot material inlet 101, and the cooling medium enters from the cold material inlet 102, flowing into the corresponding hot material flow channel 201 and cold material flow channel 202 inside the cavity cylinder 20, respectively. As the hot material and cooling medium are continuously introduced and fill their respective flow channels, the hot material and cooling medium pass through the opening slots 22 opened on the side wall of the cavity cylinder 20 and enter the spiral flow channel formed by the spiral plates 14. The two sets of spiral plates 14 spirally wind around each other, so that the hot material flow channel 201 and the cold material flow channel 202 are connected. 02 The spiral flow channels are staggered and spaced apart, and the hot material and cooling medium flow continuously in the spiral flow channel and exchange heat fully through the spiral plate 14, thereby cooling the hot material. Through this flow channel arrangement and heat exchange method, the fluid flow can be significantly extended and the effective contact area between the hot and cold fluids can be increased, making the heat exchange more sufficient and uniform. At the same time, it can enhance the turbulence effect of the fluid in the flow channel, improve the laminar flow state, thin the heat exchange boundary layer, and effectively improve the overall heat exchange efficiency. In addition, the flow channel structure can make the fluid flow smoother, reduce the risk of flow channel blockage and material residue, improve the stability and reliability of equipment operation, and meet the requirements of efficient, stable and long-term heat exchange. Furthermore, by setting a spacer column 141 between the spiral plates 14, the spacing between the spiral plates 14 can be stably limited, which can avoid the problems of deformation, collapse or flow channel closure of the spiral plates 14 under the high pressure of the material during long-term use. At the same time, when the material flows in the spiral flow channel formed by the spiral plates 14, it will continuously contact, collide and flow around the spacer column 141, thereby breaking the laminar flow state of the fluid, enhancing the turbulent disturbance of the fluid in the flow channel, thinning the heat exchange boundary layer, and making the heat transfer between the hot and cold fluids more rapid and sufficient. Moreover, this setting not only ensures the long-term stability of the flow channel cross-sectional dimensions, improves the reliability and service life of the equipment, but also further enhances the heat exchange effect and improves the overall heat exchange efficiency and heat exchange uniformity. Furthermore, during the process of hot material and cooling medium flowing into the corresponding hot material channel 201 and cold material channel 202 inside the cavity cylinder 20, by pulling the adjusting member 314 outward, the telescopic end of the telescopic rod 313 is simultaneously pulled outward. During this movement, the adjusting member 314 drives the locking block 322 to move synchronously, causing the locking block 322 to separate from the locking groove 323 on the locking block 321, thus unlocking the adjusting member 314. Then, rotating the adjusting member 314 causes the telescopic rod 313 and the adjusting screw 312 to rotate synchronously. The rod 313 can only extend and retract but not rotate, which ensures stable and reliable transmission. As the adjusting component 314 rotates continuously, the adjusting block 315 and the adjusting screw 312 are screwed together. Under the limiting action of the limiting slider 3151 and the limiting groove 3111, the adjusting block 315 only moves along the axial direction of the adjusting screw 312 and does not rotate. During the movement of the adjusting block 315, it drives the limiting slider 3151 to slide smoothly in the limiting groove 3111 on the inner wall of the adjusting column 311. This setting effectively ensures that the adjustment process is stable, accurate and reliable, and there will be no slippage, offset or rotation, thus improving the flow channel adjustment accuracy and operation stability. Simultaneously, as the adjusting block 315 moves, it pulls the wire rope 332 to move synchronously, and through the other end of the wire rope 332, it pulls the fixing strip 333. Since the fixing strip 333 is attached to the side wall of the cavity rubber plate 21, the wire rope 332 can cause the cavity rubber plate 21 to deform synchronously during the process of pulling the fixing strip 333. By independently adjusting and controlling the adjusting mechanisms 30 in the hot material flow channel 201 and cold material flow channel 202 inside the cavity cylinder 20, and by using the wire ropes 332 on both sides to pull the cavity rubber plate 21 synchronously, the cavity rubber plate 21 can form a continuous curved wave-like structure, thereby changing the flow channel shape and flow cross-section inside the cavity cylinder 20. It can actively change the flow path and flow state of the fluid, forcing the fluid to form continuous disturbance and backflow within the flow channel, further enhancing the turbulence effect, effectively breaking the laminar flow state, thinning the heat exchange boundary layer, and making the heat exchange between hot and cold fluids more sufficient and uniform. This fundamentally improves the problems of low heat exchange efficiency and uneven heat exchange in traditional flow channels. On the one hand, this setting can flexibly adjust the curvature and flow cross-sectional area of ​​the flow channel according to the viscosity, impurity content and working conditions of different materials, thereby enhancing heat exchange while reducing material blockage and residue. On the other hand, it can realize online, precise and continuous adjustment of the flow channel morphology, greatly improving the applicability and operational stability of the equipment, and further improving the overall heat exchange efficiency and reliability. Furthermore, after the adjustment component 314 has been rotated and adjusted, pressing the adjustment component 314 will squeeze the telescopic rod 313, causing the telescopic rod 313 to retract and reset. At the same time, the adjustment component 314 will drive the locking block 322 to re-embed and lock in the locking groove 323 of the locking block 321, thereby achieving the locking and positioning of the adjustment position. This setting allows the adjustment component 314, the adjustment screw 312, and the adjustment block 315 to be locked and fixed quickly and reliably after the flow channel shape is adjusted to the correct position. This effectively prevents the adjustment position from shifting, loosening, or the automatic rebound and reset of the cavity rubber plate 21 due to fluid impact, vibration, or other factors during equipment operation. It ensures that the bending and wavy shape of the flow channel remains stable for a long time, thereby ensuring that the heat exchange effect and the flow channel state are always stable and controllable, and improving the safety and reliability of equipment operation. Furthermore, when it is necessary to heat the cold material, simply connect the external cold material pipeline to the cold material inlet 102 of the heat exchanger and the heating medium pipeline to the hot material inlet 101. The cold material to be heated enters from the cold material inlet 102, and the heating medium enters from the heating inlet. They flow into the corresponding hot material flow channel 201 and cold material flow channel 202 inside the cavity cylinder 20, respectively, and finally enter the spiral flow channel formed by the spiral plate 14 to achieve the purpose of heat exchange. With this setting, the device can quickly switch between the two modes of hot material cooling and cold material heating without changing the structure or disassembling the pipeline. It can achieve multiple uses in one machine by simply switching the inlet access method of the medium. This expands the applicable working conditions and application range of the equipment, simplifies the operation process, improves the versatility and utilization rate of the equipment, reduces the production and use costs, and truly meets the needs of efficient and flexible use in various heat exchange scenarios. Furthermore, when cleaning of the heat exchanger body 10 is required, the adjusting block 315 can be moved to its initial position by rotating the adjusting component 314. Simultaneously, the partition rubber plate 21, under its own elasticity, pulls the wire rope 332 back to its initial vertical and flat state. At this point, the external cleaning water interface is connected to the hot material inlet 101 and the cold material inlet 102, and cleaning water is introduced into the interior. The cleaning water thoroughly flushes the internal flow channels. By restoring the partition rubber plate 21 to its initial vertical and flat state, the internal flow channels can be restored to a straight and smooth flow path. By eliminating dead corners and grooves formed by the curved and wavy structure, the cleaning water can flow through the entire flow channel area without obstruction or residue, completely avoiding dead corners and material accumulation areas that cannot be cleaned, greatly improving the cleaning effect and cleanliness. This design achieves a dual balance between enhanced heat exchange and convenient cleaning. When efficient heat exchange is required, a disturbed flow channel can be formed, and when cleaning and maintenance are required, it can be quickly reset to a straight and easy-to-clean flow channel. This effectively solves the problems of complex flow channels, difficult cleaning, and easy material residue in traditional heat exchangers, significantly extending the continuous operation cycle of the equipment and reducing maintenance difficulty and cost.
