Abstract
Description
Technical Field
[0001] This application belongs to the field of heat exchanger components, and specifically provides a device for a high-storage heat exchange tube for a tube winding machine. Background Technology
[0002] Spiral wound tube heat exchangers are a type of heat exchange equipment used in the chemical industry. They are characterized by high heat exchange efficiency, long service life, low fouling tendency, small space occupation, and low operating costs. Currently, they are widely used in cryogenic plants in the chemical industry, such as air separation and methanol plants. As research on spiral wound tube heat exchangers deepens, they are also developing towards larger sizes, and the length of the heat exchange tubes is also increasing accordingly.
[0003] Currently, the tube winding machine consists of a worktable, main shaft, transmission device, tube storage device, and clamping device. The tube storage device is used to store heat exchanger tubes. Currently, heat exchanger tube suppliers offer two packaging methods: bulk and cylindrical. Bulk heat exchanger tubes are produced to customer specifications, while cylindrical heat exchanger tubes are between 200-300 meters in length. For bulk heat exchanger tubes, unexpected factors during production can lead to leftover material, resulting in waste of raw materials. For cylindrical heat exchanger tubes, the original storage device's capacity is insufficient, requiring frequent manual disassembly during production, which is inefficient. Furthermore, the current power source for the heat exchanger tube storage device is the winding machine's transmission device. As the winding machine's main shaft rotates, it pulls the heat exchanger tubes on the storage device. Frequent starts and stops can cause the heat exchanger tubes to loosen and become fluffy, leading to unreliable operation. Summary of the Invention
[0004] To address the aforementioned shortcomings, this invention provides a device for high-storage heat exchange tubes used in tube winding machines, which can meet the needs of large heat exchanger cores. At the same time, the rotation of the storage tube cylinder keeps the heat exchange tube in a taut state during guidance.
[0005] An apparatus for storing heat exchange tubes in a tube winding machine is disclosed. The apparatus stores heat exchange tubes located at the device and can be transported to a heat exchanger core. The apparatus includes a tube support, a tube body, a conduit assembly, and a power assembly. The tube body is connected to the tube support and is rotatable relative to the support. The tube body is used for winding heat exchange tubes to store them. The conduit assembly is hinged to the tube support, and the heat exchange tubes located at the tube body are transported to the heat exchanger core via the conduit assembly. The power assembly includes components connected to the tube body. The device includes a main power component for dynamic connection and a secondary power component for transmission connection with a portion of the conduit assembly; wherein, when the heat exchange tube is transported from the storage tube body to the heat exchanger core, the heat exchanger core rotates to generate a first tension on the heat exchange tube at the device, and the storage tube body rotates to generate a second tension on the heat exchange tube opposite to the first tension, the first tension being greater than the second tension; when the heat exchange tube is wound around the heat exchanger core, the heat exchange tube has a residual section exposed outside the storage tube body, and the storage tube body rotates to wind the residual section around the storage tube body. When the heat exchanger core rotates, the first tensile force acting on the heat exchange tube is relatively large. Therefore, even if the rotation direction of the storage tube body and the heat exchanger core is opposite during the heat exchange tube winding process, the heat exchange tube at the storage tube body can still be pulled to the heat exchanger core to achieve the winding of the heat exchange tube. Moreover, during the winding process, since the heat exchange tube is simultaneously subjected to opposite first and second tensile forces, it can keep the heat exchange tube in a taut state, avoiding the heat exchange tube from becoming loose, which would cause the heat exchange tube to be difficult to exit and affect the operation of the storage tube body.
[0006] Furthermore, the conduit assembly includes a forced conduit end and an interlocking conduit end arranged opposite to each other, a conduit shaft located between the forced conduit end and the interlocking conduit end, and a conduit fitting that slides back and forth along the conduit shaft. The conduit shaft is a bidirectional screw structure, and the rotation direction of the forced conduit end is opposite to that of the interlocking conduit end. The conduit fitting can slide back and forth along the conduit shaft, so that when the position of the heat exchange tube changes, the position of the conduit fitting can change synchronously, ensuring that the heat exchange tube is flush between the storage tank and the conduit fitting, and avoiding bending damage to the heat exchange tube. The interlocking conduit end operates when the heat exchange tube moves normally, while the forced conduit end rewinds the heat exchange tube back to the storage tank, so that the heat exchange tubes accumulated at the conduit fitting can be rewound to the heat exchange tank, ensuring safety during use.
[0007] Furthermore, the sub-power assembly includes a hydraulic motor connected to the forced conduit end drive, and the main power assembly includes a servo motor connected to the interlocking conduit end drive. Since the interlocking conduit end starts during normal operation, i.e., the start-up time of the interlocking conduit end is relatively long, connecting it to the interlocking conduit end via a servo motor offers good energy-saving performance. Additionally, servo motors have low overall noise, low heat generation, and high efficiency, and are also easier to operate. The hydraulic motor connected to the forced conduit end easily obtains greater force and torque, thus facilitating the rapid guidance of the heat exchange tubes to the storage tank. It also allows for rapid start-up and shutdown with minimal current surge.
[0008] Furthermore, a first sprocket is provided at the forced guide tube end, which is connected to the hydraulic motor via a torque limiter. A second sprocket is provided at the interlocked guide tube end, which is connected to the servo motor. The hydraulic motor drives the guide tube shaft to rotate via the first sprocket, thereby realizing the reciprocating movement of the guide tube components at the guide tube shaft. The servo motor drives the guide tube shaft to rotate via the second sprocket, which also realizes the reciprocating movement of the guide tube components at the guide tube shaft.
[0009] Furthermore, the catheter assembly also includes sliding sleeves disposed on both sides of the catheter shaft to support it. By providing sliding sleeves, the catheter shaft can be made more stable after installation.
[0010] Furthermore, the storage tube body has a transmission end and a connecting end that are installed at the storage tube support and are arranged opposite to each other. The transmission end is connected to the main power component, and the connecting end is fixed to the storage tube support by a self-aligning roller bearing.
[0011] Furthermore, the device also includes a lifting assembly that supports the storage tube bracket. The lifting assembly moves vertically to move the storage tube bracket. By raising and lowering the lifting assembly, the height of the device can be adjusted. This not only lowers the device to facilitate maintenance and inspection, but also allows the device to be adapted to the height of the heat exchanger core to be wound, thus facilitating the transport of the heat exchanger tubes.
[0012] Furthermore, the lifting assembly includes a scissor lift capable of vertical movement and a rotating platform mounted on the scissor lift. The rotating platform supports the storage tube bracket and is connected to the scissor lift via a slewing bearing. The scissor lift enables the lifting and lowering of the device. Its mechanical structure offers high stability during lifting and a high load-bearing capacity, allowing for a larger working platform, thus expanding the high-altitude work area and accommodating multiple workers simultaneously, resulting in higher work efficiency and enhanced safety. The rotating platform, located at the scissor lift, can rotate relative to the scissor lift, enabling adjustment not only of the storage tube's height but also its angle to adapt to different operating environments.
[0013] Furthermore, along the axial direction of the storage tank, maintenance platforms are provided on both sides of the scissor lift. These platforms are hinged to the scissor lift, and both ends are fixed to the lift by chains. When the maintenance platforms are in a horizontal position, they are located outside the scissor lift. These maintenance platforms facilitate worker standing for maintenance or inspection of the storage tank. The platforms, secured by chains, are horizontal when in use and retract vertically when not in use, reducing floor space. When the maintenance platforms are horizontal for worker standing, their location outside the scissor lift ensures a safe distance between the worker and the storage tank.
[0014] Furthermore, the surface of the maintenance pedal is provided with anti-slip texture; by setting anti-slip texture, it can play a role in preventing workers from slipping when they stand on the maintenance pedal, preventing workers from falling, and better protecting workers.

[0027] Finally, it should be noted that when a component is said to be "located on" or "set on" another component, it can be on the other component or may have an intervening component at the same time. When a component is said to be "connected to" another component, it can be directly connected to the other component or may have an intervening component at the same time.
[0028] like Figure 1 and Figure 2 The invention discloses a device for storing heat exchange tubes in a tube winding machine. The device can store heat exchange tubes, and the heat exchange tubes located in the device can be transported to the heat exchanger core. In this application, the heat exchange tubes are wound in the heat exchanger. The wound tube heat exchanger is a heat exchange equipment in the chemical industry, which has the characteristics of high heat exchange efficiency, long service life, low scaling tendency, small space occupation, and low operating cost. It is currently widely used in cryogenic plants in the chemical industry, such as air separation and methanol plants. With the in-depth research on wound tube heat exchangers, wound tube heat exchangers are also developing towards larger sizes, and the length of the heat exchange tubes is also increasing accordingly. In this application, the heat exchange tube 4 can be wound in the storage tube cylinder 2 to realize the storage of the heat exchange tube 4 in the storage tube cylinder 2. Compared with the bulk heat exchange tubes, in this application, the heat exchange tube 4 is wound in the storage tube cylinder 2 to realize the centralized storage of the heat exchange tube 4. The heat exchange tube 4 stored in the storage tube cylinder 2 can meet the needs of large-size heat exchanger cores.
[0029] In this application, the storage tube 2 can be used to wind the heat exchange tube 4, thereby realizing the storage of the heat exchange tube 4. When it is necessary to wind the heat exchange tube 4 to the heat exchanger core, it is only necessary to guide the heat exchange tube 4 on the storage tube 2 to the heat exchanger core. When the heat exchange tube 4 stored in the storage tube 2 is fully loaded, the heat exchange tube 4 at the storage tube 2 can meet the needs of multiple heat exchanger cores. Since the heat exchange tube 4 stored in the storage tube 2 is continuously arranged, after winding one heat exchanger core, it is only necessary to cut the heat exchange tube 4 to deliver the heat exchange tube 4 to the next heat exchanger core. Therefore, after the heat exchange tube 4 is wound on the storage tube 2, it can be directly wound to the heat exchanger core without removing the heat exchange tube 4, thereby reducing the frequent disassembly of the heat exchange tube 4.
[0030] As one embodiment of this application, the device includes a storage tube support 1, a storage tube cylinder 2, a conduit assembly 3, and a power assembly. The storage tube cylinder 2 is connected to the storage tube support 1 and can rotate relative to the storage tube support 1. Since the storage tube cylinder 2 has a cylindrical structure, the heat exchange tube 4 also has a circumferential structure after being wound around the storage tube cylinder 2. In this application, the storage tube cylinder 2 can rotate. Whether it is when the heat exchange tube 4 is wound around the storage tube cylinder 2, the storage tube cylinder 2 rotates to make the heat exchange tube 4 wind layer by layer, or when the heat exchange tube 4 is guided to the heat exchanger core, the storage tube cylinder 2 can also rotate to facilitate the transportation of the heat exchange tube 4, so as to reduce the resistance encountered by the heat exchange tube 4 when it is moved out of the heat exchanger core.
[0031] Specifically, this application includes a conduit assembly 3 and a power assembly. The conduit assembly 3 is hinged to the storage tube support 1. The heat exchange tube 4 located at the storage tube body 2 is transported to the heat exchanger core via the conduit assembly 3. The power assembly includes a main power assembly that is driven by the storage tube body 2 and a secondary power assembly that is driven by a portion of the conduit assembly 3. Through the conduit assembly 3 and the power assembly, the heat exchange tube 4 at the storage tube body 2 can be transported to the heat exchanger core, realizing the winding of the heat exchange tube 4. During the transport of the heat exchange tube 4, since the storage tube body 2 can rotate relative to the storage tube support 1, the rotation of the storage tube body 2 will also drive the heat exchange tube 4 to move. In the state where the heat exchange tube 4 is transported from the storage tube body 2 to the heat exchanger core, the rotation of the heat exchanger core pulls the heat exchange tube 4 of the storage tube body 2 to the heat exchanger core. A first pulling force is generated on the heat exchange tube 4 at the device. Since the storage tube 2 can also rotate, the rotation direction of the storage tube 2 is opposite to the rotation direction of the heat exchanger core. This causes the storage tube 2 to rotate and generate a second pulling force on the heat exchange tube 4 that is opposite to the first pulling force. The first pulling force is greater than the second pulling force. When the heat exchanger core rotates, the first pulling force acting on the heat exchange tube 4 is relatively large. Therefore, even if the rotation direction of the storage tube 2 and the heat exchanger core is opposite during the winding process of the heat exchange tube 4, the heat exchange tube 4 at the storage tube 2 can still be pulled to the heat exchanger core, realizing the winding of the heat exchange tube 4. During the winding process of the heat exchange tube 4, since the heat exchange tube 4 is simultaneously subjected to the opposite first and second pulling forces, the heat exchange tube 4 can be kept in a taut state, avoiding the heat exchange tube 4 from becoming loose, which would cause the heat exchange tube 4 to be difficult to exit and affect the operation of the storage tube 2.
[0032] In this application, after the heat exchanger core is wound, the heat exchanger tube 4 needs to be cut to separate the heat exchanger tube 4 at the storage tube body 2 from the heat exchanger core, so as to facilitate the subsequent winding of the heat exchanger core. After the heat exchanger tube 4 is cut, there is a residual section exposed outside the storage tube body 2. The storage tube body 2 rotates to wind the residual section to the storage tube body 2. During the winding process, the first pulling force of the heat exchanger core on the heat exchanger tube 4 pulls the heat exchanger tube 4 towards the heat exchanger core, while the second pulling force of the storage tube body 2 pulls the heat exchanger tube 4 towards the storage tube body 2. Therefore, after the heat exchanger tube 4 is cut, the storage tube body 2 can continue to rotate, and the cut heat exchanger tube 4 is no longer subjected to the first pulling force. Therefore, it can be re-wound to the storage tube body 2, avoiding the heat exchanger tube 4 being exposed outside the storage tube body 2.
[0033] In this application, the storage tube body 2 has a transmission end and a connecting end installed on the storage tube support 1 and arranged opposite to each other. The transmission end is connected to the main power component, and the connecting end is fixed to the storage tube support 1 by a self-aligning roller bearing. The storage tube body 2 is fixed at the storage tube body 2 by the transmission end and the connecting end. The transmission end is connected to the main power component, that is, the main power component drives the transmission end to rotate, thereby realizing the rotation of the entire storage tube body 2. The connecting end, together with the transmission end, realizes the installation of the storage tube body 2, ensuring the stability of the storage tube body 2 under force.
[0034] Preferably, the device further includes a lifting assembly 5 that supports the storage tube support 1. The lifting assembly 5 moves in a vertical direction to drive the storage tube support 1 to move. By lifting the lifting assembly 5, the height of the device can be adjusted. This not only lowers the height of the device to facilitate maintenance and inspection, but also allows the device to be adapted to the height of the heat exchanger core that needs to be wound, thus facilitating the transport of the heat exchange tube 4.
[0035] As one embodiment of this application, the lifting assembly 5 includes a scissor lift 51 capable of moving vertically and a rotating platform 52 disposed on the scissor lift 51. The rotating platform 52 supports the storage tube bracket 1 and is connected to the scissor lift 51 via a slewing bearing. The lifting and lowering of the device is achieved through the scissor lift 51. The scissor mechanical structure has high stability during lifting and high load-bearing capacity. It can be combined with a large working platform to expand the high-altitude working range and is suitable for multiple people to work simultaneously, thereby increasing work efficiency and ensuring safety. At the same time, the rotating platform 52 is provided at the scissor lift 51. The rotating platform 52 can rotate relative to the scissor lift 51, so that not only the height of the storage tube 2 can be adjusted, but also the angle of the storage tube 2 can be adjusted to adapt to different usage environments.
[0036] In this application, maintenance pedals 511 are provided on both sides of the scissor lift 51 along the axial direction of the storage cylinder 2. The maintenance pedals 511 are hinged to the scissor lift 51, and both ends of the maintenance pedals 511 are fixed to the scissor lift 51 by chains. When the maintenance pedals 511 are in a horizontal state, they are located outside the scissor lift 51. By providing maintenance pedals 511, it is convenient for workers to stand up and perform maintenance or inspection on the storage cylinder 2. The maintenance pedals 511 are fixed by chains. When in use, the maintenance pedals 511 are fixed in a horizontal state. When not in use, the maintenance pedals 511 can be folded up to a vertical state, reducing the floor space occupied. When the maintenance pedals are in a horizontal state for workers to stand on, the maintenance pedals 511 are located outside the scissor lift 51, so that workers can maintain a certain distance from the storage cylinder 2 and protect their safety.
[0037] Preferably, the surface of the maintenance pedal 511 is provided with anti-slip texture; by providing anti-slip texture, when the worker stands on the maintenance pedal 511, it can play an anti-slip role, prevent the worker from falling, and better protect the worker.
[0038] As one embodiment of this application, the maintenance spring plate is a grid, which is lightweight, facilitates the fixing or unfolding of the maintenance pedal, and has a good anti-slip effect.
[0039] like Figure 2 As shown, in this application, the conduit assembly 3 includes a forced conduit end 31 and an interlocking conduit end 32 disposed opposite to each other, a conduit shaft 33 located between the forced conduit end 31 and the interlocking conduit end 32, and a conduit member 34 that slides back and forth along the conduit shaft 33. The conduit shaft 33 is a bidirectional screw structure, and the rotation direction of the forced conduit end 31 is opposite to the rotation direction of the interlocking conduit end 32. The forced conduit end 31 and the interlocking conduit end 32 enable the conduit shaft 33 to be in different rotation directions. When the whole is operating normally, the interlocking conduit end 32 operates, causing the heat exchange tube 4 to move from the storage tube 2 to the heat exchange tube 4 cylinder through the conduit member 34. At the core, since the heat exchange tube 4 is wound around the storage tube cylinder 2, and during the winding process, one layer is first laid flat before a new layer is wound on top of the previous layer, when the heat exchange tube 4 is removed from the storage tube cylinder 2, the point where the heat exchange tube 4 is removed will move back and forth in the axial direction of the storage tube cylinder 2, so that the heat exchange tube 4 can be extracted layer by layer. Meanwhile, the guide tube 34 can slide back and forth along the guide tube shaft 33, so that when the position of the heat exchange tube 4 changes, the position of the guide tube 34 can change synchronously, ensuring that the heat exchange tube 4 is flush between the storage tube cylinder 2 and the guide tube 34, and avoiding bending and damage to the heat exchange tube 4.
[0040] The interlocking guide tube end 32 operates when the heat exchange tube 4 is moving normally. However, if the heat exchange tube 4 malfunctions, such as getting stuck at the guide tube component 34, but still continues to move out of the storage tank 2 under the action of the heat exchanger core, heat exchange tube 4 will accumulate at the guide tube component 34. This not only causes the heat exchange tube 4 to bend, affecting subsequent use, but also, if too much accumulates, it can jam the storage tank 2, preventing it from rotating normally. This increases the current of the main power component driving the storage tank 2, which can be dangerous. At this point, the interlocking guide tube end 32 switches to the forced guide tube end 31. Since the interlocking conduit end 32 removes the heat exchange tube 4 from the storage cylinder 2, the forced conduit end 31 rewinds the heat exchange tube 4 back to the storage cylinder 2, so that the heat exchange tube 4 accumulated at the conduit part 34 can be rewinded to the heat exchange cylinder, ensuring safety during use; or, when the worker finds that the heat exchange tube 4 is incorrectly welded to the heat exchanger core, such as the position of the heat exchange tube 4 being incorrectly welded, it is also necessary to turn the heat exchange tube 4 back to the storage cylinder 2 and then remove the heat exchange tube 4 again. At this time, the forced conduit end 31 can also be activated to pull the heat exchange tube 4 outside the storage cylinder 2 back to the storage cylinder 2.
[0041] Understandably, in this application, the first pulling force exerted by the storage tube 2 on the heat exchange tube 4 is the force generated when the interlocking guide end 32 is running, i.e. when the heat exchange tube 4 is normally wound. When the forced guide end 31 is started, since the forced guide end 31 rewinds the heat exchange tube 4 to the storage tube 2, the first pulling force will be increased after the forced guide end 31 is started to ensure that the accumulated heat exchange tube 4 can be rewinded to the storage tube 2.
[0042] In this application, when a fault occurs and it is necessary to automatically switch from the interlocking conduit end 32 to the forced conduit end 31, a current sensor can be set at the active power component. When a large change in current is detected, the forced conduit end is activated to work. The installation of the current sensor and the connection of the circuit in this application can be found in the prior art, and will not be described in detail here.
[0043] Preferably, the power component includes a hydraulic motor that is driven and connected to the forced conduit end 31, and the main power component includes a servo motor that is driven and connected to the interlocking conduit end 32. Since the interlocking conduit end 32 is started during normal operation, that is, the start-up time of the interlocking conduit end 32 is relatively long, so the servo motor is used to drive and connect to the interlocking conduit end 32. The servo motor has good energy saving effect, and the servo motor has low noise, low heat generation, and high efficiency. At the same time, the operation of the servo motor is also more convenient. The hydraulic motor connected to the forced conduit end 31 can easily obtain a large force and torque, so as to facilitate the rapid guidance of the heat exchange tube 4 to the storage cylinder 2. At the same time, it can be started and stopped quickly, with little current impact.
[0044] A first sprocket is provided at the forced guide tube end 31, and the first sprocket is connected to the hydraulic motor through a torque limiter. A second sprocket is provided at the interlocked guide tube end 32, and is connected to the servo motor. The hydraulic motor drives the guide tube shaft 33 to rotate through the first sprocket, thereby realizing the reciprocating movement of the guide tube component 34 at the guide tube shaft 33. The servo motor drives the guide tube shaft 33 to rotate through the second sprocket, which can also realize the reciprocating movement of the guide tube component 34 at the guide tube shaft 33.
[0045] Preferably, the catheter assembly 3 further includes sliding sleeves disposed on both sides of the catheter shaft 33 to support the catheter shaft 33; by providing sliding sleeves, the catheter shaft 33 can be made more stable after installation.
[0046] The above description is merely an embodiment of this application and is not intended to limit the scope of this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of the claims of this application.
