Description

Technical Field

[0001] This utility model relates to heat exchange tubes in the field of wound tube heat exchangers, and particularly to a heat exchange tube conveying device for wound tube heat exchangers. Background Technology

[0002] The heat exchange tubes of a wound-tube heat exchanger possess high heat transfer efficiency and are widely used in industrial fields due to their high efficiency, energy saving, and compact structure. The core component of a wound-tube heat exchanger is the spiral heat exchange tubes, which are tightly wound around a central tube, forming a multi-layered spiral structure. The spiral shape increases the contact area and improves heat transfer efficiency. The heat exchange tubes are typically made of copper, stainless steel, or carbon steel, possessing good corrosion resistance and mechanical strength. For example, copper tubes are suitable for low-temperature, high-pressure environments, while stainless steel tubes are more suitable for high-temperature, high-pressure conditions. The diameter of the heat exchange tubes is generally 8-25 mm, and the length can be adjusted according to actual needs. The shell consists of the shell, tube bundle, end caps, and flanges, and the shell is typically made of carbon steel or stainless steel.

[0003] In a wound-tube heat exchanger, the heat exchange tubes are typically fixed between the core and the shell using a helical winding method, forming a multi-layer structure. Each layer of heat exchange tubes is wound in opposite directions to increase the heat transfer coefficient and reduce fluid turbulence, thereby improving heat transfer efficiency. The heat exchange tubes are helically wound through the central hole of the core, and each layer is separated by spacers to maintain a certain spacing and helix angle. This improves heat transfer efficiency and effectively compensates for thermal expansion, reducing stress caused by temperature differences. Because the heat exchange tubes in a wound-tube heat exchanger have a helical design, turbulence is generated when the fluid flows inside the tubes, enhancing convective heat transfer. Furthermore, the shell-side medium flows in the opposite direction, avoiding dead zones and fouling accumulation, further improving heat transfer efficiency.

[0004] However, in the process of implementing the inventive technical solution in the embodiments of this application, the inventors of this application discovered that the above-mentioned technology has at least the following technical problems:

[0005] When winding heat exchanger tubes, it is necessary to ensure a smooth transition and uniform gap during the winding process. Currently, the conveying and winding of heat exchanger tubes rely on manual control of the force and angle, which cannot be consistently maintained, making it difficult to control errors. Summary of the Invention

[0006] To address the shortcomings of existing technologies and the issue of controlling the transition and gap during the winding of heat exchanger tubes, this application provides a heat exchanger tube conveying device for wound heat exchangers. This conveying device adjusts the height of the tube coil by setting a lifting mechanism on a transport vehicle, making it correspond to the height of the supporting core cylinder, thus meeting the winding requirements for the heat exchanger tubes and solving the technical problem of controlling the transition and gap during the winding of the heat exchanger tubes.

[0008] The heat exchanger tube conveying device for a wound-tube heat exchanger includes a tube coil, a support, a lifting mechanism, a transport vehicle, and a cable winding and unwinding rack. The tube coil is used to hold the wound heat exchanger tubes, which have a through-hole shaft. The heat exchanger tubes are guided out by guide rollers for the winding operation of the wound-tube heat exchanger. The support is located at both ends of the tube coil to support the shaft, lift and fix the tube coil. The lifting mechanism is connected to the support and is used to adjust the height of the support. It has a lifting power component, and by adjusting the position of the tube coil, the outgoing heat exchanger tubes are matched with the support core cylinder. The transport vehicle houses the lifting mechanism and has a travel power component, which can move the tube coil parallel to the axis of the support core cylinder. As the support core cylinder rotates, the heat exchanger tubes are gradually wound around the support core cylinder. The cable winding and unwinding rack is located on the transport vehicle. When the transport vehicle moves along the axis of the support core cylinder, it winds and unwinds the cables of the electrical components in the lifting power component and the travel power component.

[0019] Positive effects:

[0020] The technical solutions provided in this application embodiment have at least the following technical effects or advantages:

[0021] 1. Because the embodiments of this application adopt the technical means of setting up a lifting mechanism on the transport vehicle, the support is assembled on the lifting mechanism and the height can be adjusted. The tube coil is set between the two supports, which effectively solves the technical problem of controlling the winding transition and gap of the heat exchange tube in the prior art. After the coiled heat exchange tube is discharged from the tube coil, it can not only be translated along the axis of the support core, but also the height of the heat exchange tube discharge can be adjusted to correspond with the support core, ensuring the smooth transition and uniform gap of the heat exchange tube during the winding process, thereby achieving the technical effect of controlling the winding operation of the heat exchange tube of the wound tube heat exchanger.

[0022] 2. Because the embodiments of this application adopt the technical means of setting guide rollers at the outlet end of the heat exchange tube of the tube coil, the heat exchange tube is conveyed to the support core cylinder after being squeezed by the guide rollers, and then the heat exchange tube is wound. This effectively solves the technical problem of controlling the winding transition and gap of the heat exchange tube in the prior art. It can keep the heat exchange tube straight before entering the support core cylinder, which facilitates the heat exchange tube to enter the support core cylinder smoothly for winding, thereby achieving the technical effect of controlling the winding operation of the heat exchange tube of the wound tube heat exchanger.

[0023] 3. Because the embodiments of this application adopt the technical means of setting up a lifting mechanism on the transport vehicle and connecting the inner side of the screw nut to the support, when the screw rotates, the screw nut rises and falls, driving the support to adjust its height, adjusting the center height of the tube coil to adapt to support cores of different diameters, and the heat exchange tubes and support cores are positioned accordingly, ensuring accurate winding of the heat exchange tubes. This effectively solves the technical problems of controlling the winding transition and gap of heat exchange tubes in the prior art, solves the problem of inconsistent force and angle during winding, achieves smooth tube feeding of heat exchange tubes, reduces tube feeding resistance, and allows for the production of wound tube heat exchangers of different specifications according to product size, thereby achieving the technical effect of controlling the winding operation of heat exchange tubes in wound tube heat exchangers.

[0024] 4. Because the embodiment of this application adopts the technical means of setting a fourth pulley at the outer end of the cable winding frame, and is connected to the third pulley on the transport vehicle through the third transmission belt, the technical problem of controlling the winding transition and gap of the heat exchange tube in the prior art is effectively solved. The cables of the electrical appliances in the lifting power component and the walking power component can be wound and released with the transport vehicle to ensure their unobstructed operation, thereby realizing the technical effect of controlling the winding operation of the heat exchange tube of the wound tube heat exchanger.

[0025] 5. Since the embodiments of this application adopt the technical means of setting a stabilizing frame on the side of the transport vehicle adjacent to the supporting core cylinder, when the transport vehicle is tilted to the side under force, the column foot can assist in supporting the transport vehicle and prevent the tube coil from falling towards the supporting core cylinder. This effectively solves the technical problem of controlling the transition and gap of heat exchange tube winding in the prior art, improves the safety of transport vehicle operation, and thus achieves the technical effect of controlling the heat exchange tube winding operation of the wound tube heat exchanger.

[0088] This application provides a heat exchange tube conveying device for a wound tube heat exchanger, which solves the problem that the heat exchange tube 110 is difficult to control and adjust in the prior art of wound tube heat exchangers. During the winding of the heat exchange tube 110, the lifting mechanism 300 is used to adjust the support 200, thereby realizing the corresponding adjustment of the height of the tube coil 100 and meeting the winding process requirements of the wound tube heat exchanger.

[0089] As shown in the figure, the heat exchange tube conveying device for the wound tube heat exchanger includes a tube coil 100, a support 200, a lifting mechanism 300, a transport vehicle 400, and a cable winding and unwinding rack 500.

[0090] The tube coil 100 is used to store the heat exchange tubes 110 wound into shape in the wound tube heat exchanger. The tube coil 100 has a through-through disc shaft 130. The heat exchange tubes 110 are guided out by the guide rollers 140 for the winding operation of the heat exchange tubes 110 in the wound tube heat exchanger.

[0091] Supports 200 are provided at both ends of the tube disc 100 to support the disc shaft 130, and to support and fix the tube disc 100.

[0092] The lifting mechanism 300 is connected to the support 200 and is used to adjust the height of the support 200. It has a lifting power component, thereby adjusting the position of the tube coil 100. By lifting the tube coil 100, the heat exchange tube 110 is matched with the support core cylinder, and the heat exchange tube 110 is wound around the support core cylinder.

[0093] The transport vehicle 400 is used to house the lifting mechanism 300 and has a walking power component, which can move the tube coil 100 parallel to the axis of the support core cylinder. As the support core cylinder rotates, the heat exchange tube 110 is gradually wound around the support core cylinder.

[0094] The cable take-up and undo frame 500 is located on the transport vehicle 400. When the transport vehicle 400 moves along the axis of the support core cylinder, it takes up and undoes the cables of the electrical components in the lifting power component and the traveling power component to meet the requirements of manufacturing wound tube heat exchangers.

[0095] The technical solutions described in the embodiments of this application have at least the following technical effects or advantages:

[0096] Since the transport vehicle 400 is equipped with a lifting mechanism 300 and the support 200 is mounted on the lifting mechanism 300, the height of the tube coil 100 can be adjusted. The tube coil 100 is placed between the two supports 200. Therefore, after the coiled heat exchange tube 110 is led out of the tube coil 100, it can not only move along the axis of the support core cylinder, but also adjust the height of the heat exchange tube 110 to correspond with the support core cylinder. This ensures a smooth transition and uniform gap of the heat exchange tube 110 during the winding process, and the heat exchange tube 110 is gradually wound around the support core cylinder, thereby carrying out the winding operation of the heat exchange tube 110 of the wound tube heat exchanger.

[0097] To ensure the stability of the structure in this embodiment, the tube disc 100 is a circular structure, including a disc cover 120, a disc shaft 130, and a guide roller 140;

[0098] The disc cover 120 has a cover-type structure with an openable cover plate at one end, which facilitates the storage of the coiled heat exchange tube 110 in the disc cover 120; the side end of the disc cover 120 is provided with a conduit 111 to form an outlet, through which the heat exchange tube 110 is led out of the disc cover 120.

[0099] The disc shaft 130 is a stepped shaft, and the coiled heat exchange tube 110 is fitted on the disc shaft 130. The disc shaft 130 extends through the disc cover 120 to both ends and is used to be mounted on the support 200.

[0100] The guide roller 140 is located at the outlet end of the disc cover 120 and is used to press the heat exchange tube 110 to a smooth transition.

[0101] In this embodiment, the tube coil 100 sits on the support 200 via the coil shaft 130. The cover is opened and the coiled heat exchange tube 110 is inserted. The heat exchange tube 100 is conveyed to the support core cylinder after being squeezed by the guide roller 140 through the guide tube 111, thereby realizing the winding operation of the heat exchange tube 110.

[0102] The technical solutions described in the embodiments of this application have at least the following technical effects or advantages:

[0103] Since the heat exchange tube 110 of the tube coil 100 is provided with a guide roller 140 at the outlet end, the heat exchange tube 110 is conveyed to the support core cylinder after being squeezed by the guide roller 140. Thus, the winding operation of the heat exchange tube 110 can keep the heat exchange tube 110 straight before entering the support core cylinder, which facilitates the heat exchange tube 110 to smoothly enter the support core cylinder for winding.

[0104] As a conventional technical choice, the support 200 is a block structure, connected to the lifting mechanism 300 and raised and lowered accordingly to adjust its height. An open groove is provided on the top of the support to support the lifting tube plate 100.

[0105] In this embodiment, specifically, the groove corresponds to the disc shaft 130. The disc shaft 130 is placed in the groove to fix the tube disc. When the heat exchange tube 110 is used up, the disc shaft 130 can be lifted to replace it.

[0106] To further ensure the stability of the structure in this embodiment, the transport vehicle 400 includes a vehicle body 410, a rolling assembly, a walking power assembly, and a track 480;

[0107] The car body 410 is a frame structure, the rolling assembly is located at the lower part of the car body 410, and the track 480 is arranged in parallel on one side of the support core cylinder; a travel power assembly is provided at the upper part of the car body 410, which drives the rolling assembly so that the car body slides along the track 480.

[0108] The rolling assembly includes rollers 420 and rollers 430; rollers 420 are evenly distributed on the lower part of the vehicle body 410 and are connected and fixed by a hanger; rollers 430 are mounted on the rollers 420, and the rollers 430 roll in contact with the track 480, driving the vehicle body 410 to move along the track 480; wherein, a second pulley 440 is provided at one end of one roller 420 for connecting to the travel power assembly, and a third pulley 490 is provided at the other end for connecting to the cable take-up and take-down frame 500, so that the cable take-up and take-down frame 500 rotates with the rollers 430 to realize the take-up and take-down of the cable;

[0109] The walking power assembly includes a walking reduction motor 460, a first pulley 450, and a first transmission belt 470. The walking reduction motor 460 is installed on the upper part of the vehicle body 410. The first pulley 450 is installed at the output end of the walking reduction motor 460. The first pulley 450 is connected to the second pulley 440 through the first transmission belt 470 to form a power transmission, thereby enabling the transport vehicle 400 to walk on the track 480.

[0110] In this embodiment, the vehicle body 410 is a welded structural component, and rollers 430 are evenly distributed on the lower part of the vehicle body 410 to slide along the track 480. Among them, a second pulley 440 and a third pulley 490 are assembled on the outer end of a roller 420. The travel reduction motor 460 drives the rollers 430, and the transport vehicle 400 travels along the track 480. At the same time, the cable winding and unwinding frame 500 moves with the translation of the transport vehicle 400 and can rotate to wind and unwind cables, so as to realize the unobstructed operation of the transport vehicle 400.

[0111] To optimize the structure of this embodiment, the lifting mechanism 300 includes a lifting power assembly, a frame 340, a lead screw 350, a driven pulley 360, a lead screw nut 370, a baffle 380, and an end plate 390.

[0112] The lifting power assembly includes a lifting reduction motor 310, a drive pulley 320, and a second transmission belt 330. The lifting reduction motor 310 is located in the middle of the transport vehicle 400, and the drive pulley 320 is provided at the output end of the lifting reduction motor 310. The drive pulley 320 transmits power in both directions through the second transmission belt 330.

[0113] The frame 340 is a vertical frame, located on both sides of the lifting and reducing motor 310. An end plate 390 is located at the top of the frame 340, and a baffle 380 is located in the middle of the frame 340. A lead screw 350 is mounted and positioned between the end plate 390 and the baffle 380. A driven pulley 360 is located at the bottom of the lead screw 350, which is connected to the driving pulley 320 via a second transmission belt 330 for power transmission. A lead screw nut 370 is mounted on the upper part of the lead screw 350. The inner side of 70 is connected to the support 200; symmetrical screws 341 are provided between the end plate 390 and the baffle 380, and the nut 370 is fitted on the screw 341. The screw 341 is used to guide and limit the nut 370. When the screw 350 rotates, the nut 370 rises and falls, thereby driving the support 200 to adjust its height, thereby realizing the adjustment of the height of the tube coil 100. The heat exchange tube 110 and the support core are positioned accordingly to meet the process requirements of the heat exchange tube 110 winding.

[0114] The technical solutions described in the embodiments of this application have at least the following technical effects or advantages:

[0115] Because a lifting mechanism 300 is installed on the transport vehicle 400, and the inner side of the screw nut 370 is connected to the support 200, when the screw 350 rotates, the screw nut 370 rises and falls, driving the support 200 to adjust its height, adjusting the center height of the tube coil 100 to adapt to support cores of different diameters. The heat exchange tube 110 is positioned in accordance with the support core, ensuring that the heat exchange tube 110 is wound accurately. This solves the problem of inconsistent force and angle during tube winding, ensuring smooth tube feeding of the heat exchange tube 110 and reducing tube feeding resistance. Different specifications of wound tube heat exchangers can be manufactured according to the product size.

[0116] In this embodiment, the lifting reduction motor 310 and the walking reduction motor 460 are variable frequency motors, which can adjust the walking speed of the transport vehicle 400 to match the winding speed of the heat exchange tube 110.

[0117] To further optimize the structure of this embodiment, the cable take-up and release frame 500 includes a cable drum 510, a take-up and release shaft 520, and a bearing and bearing seat assembly 530.

[0118] The cable reel 510 is equipped with a U-shaped groove for storing cables. A take-up and undo shaft 520 is installed through the middle of the cable reel 510. Bearings and bearing seat assemblies 530 are installed at both ends of the take-up and undo shaft 520. The cable take-up and undo frame 500 is mounted on the transport vehicle 400 through the bearings and bearing seat assemblies 530. A fourth pulley 540 is installed at the outer end of the take-up and undo shaft 520. The fourth pulley 540 is connected to the third pulley 490 on the transport vehicle 400 through the third transmission belt 550. Thus, the cable take-up and undo frame 500 rotates as the transport vehicle 400 slides, thereby realizing the take-up and undo of cables and ensuring the unobstructed operation of the transport vehicle 400.

[0119] The technical solutions described in the embodiments of this application have at least the following technical effects or advantages:

[0120] Because the cable retractor 500 is equipped with a fourth pulley 540 at its outer end, which is connected to the third pulley 490 on the transport vehicle 400 via a third transmission belt 550, the cables of the electrical components in the lifting power assembly and the traveling power assembly can be retracted and extended along with the transport vehicle 400, ensuring their unobstructed operation.

[0121] To further optimize the structure of this embodiment and to improve the operational safety of the heat exchange tube conveying device of the wound tube heat exchanger, a stabilizing frame 600 is also provided; the stabilizing frame 600 includes column bases 610, inclined beams 620 and crossbeams 630.

A crossbeam 630 is provided in the middle of the stabilizing frame 600 and connected to the body 410 of the transport vehicle 400. The stabilizing frame 600 is connected to the side of the heat exchange tube conveying device of the wound tube heat exchanger. A column foot 610 is provided at the lower part of the stabilizing frame 600 to prevent the transport vehicle 400 from tilting to the side and falling towards the support core. It helps to maintain the balance of the transport vehicle 400, which not only improves the stability of the transport vehicle 400, but also prevents the transport vehicle 400 from deviating from the track 480 and improves the safety of the transport vehicle 400 sliding along the track 480.

[0123] The technical solutions described in the embodiments of this application have at least the following technical effects or advantages:

[0124] Since a stabilizer 600 is installed on the side of the transport vehicle 400 adjacent to the support core cylinder, when the transport vehicle 400 is tilted to the side under force, the column foot 610 can help support the transport vehicle 400, prevent the tube coil 100 from falling towards the support core cylinder, and improve the safety of the transport vehicle 400 operation.

[0125] The working process of this embodiment:

[0126] Includes the following steps:

[0127] A. Fix the 480 track according to the design dimensions first;
