Description

Technical Field

[0001] The present application relates to the technical field of foundation treatment, and in particular to a spiral heat exchange tube with good stability. Background Art

[0002] A spiral heat exchange tube is a component of equipment used to achieve heat exchange. It is usually composed of one or more groups of tubes wound into a spiral shape. The spiral structure of the spiral heat exchange tube can extend the flow path of the fluid in the tube and enhance the turbulence of the fluid, thereby improving the heat exchange efficiency. At the same time, more heat exchange area can be arranged in the same space, making the equipment structure more compact and saving installation space.

[0003] However, existing spiral heat exchange tubes are usually processed using a straight-pull process. The straight-pull process causes the cross-sectional area of ​​the two ports of the spiral heat exchange tube to be the same as the cross-sectional area of ​​the spiral section, making the interface plate size larger. This not only increases material consumption, but also the interface plate occupies more space, which is not conducive to the miniaturization and compact design of the overall structure of the equipment.

[0004] On the other hand, the length of the spiral pipe is usually too long. During transportation, transfer or installation and fixation, the middle section bears its own gravity and radial stress of the spiral structure for a long time. The repeated stress will cause irreversible fatigue damage to the pipe body. In severe cases, it may collapse, deform and even break. This will reduce the service life of the spiral pipe and there are obvious shortcomings. Summary of the Invention

[0005] In order to reduce the size of the interface plate and increase the service life of the spiral tube, the present application provides a spiral heat exchange tube with good stability.

[0006] The present application provides a spiral heat exchange tube with good stability, which adopts the following technical solution: A spiral heat exchange tube with good stability includes two oppositely arranged interface plates, multiple spiral tubes are arranged between the two interface plates, and each spiral tube is provided with a bent tube at both ends. The bending direction of the bent tube is set toward the axis direction of the interface plate. The bent tube is set on the interface plate, and multiple support members are commonly provided on the outer surfaces of multiple spiral tubes.

[0007] By adopting the above technical solution, the inward-bent bent tube connecting the spiral tube and the interface disk can shorten the distance between the end of the spiral tube and the axis of the interface disk, thereby reducing the size of the interface disk and making the interface disk occupy a smaller space. At the same time, multiple support members are used to form multiple sections of support in the length direction of the spiral tube, dispersing the gravity and radial stress borne by the middle section, thereby reducing the possibility of collapse and fracture of the spiral tube due to stress concentration in the middle section, and improving the service life of the spiral tube.

[0008] Optionally, the support member is a support ring sleeved on the outer surfaces of the plurality of spiral tubes, the plurality of support rings are evenly arranged along the length direction of the spiral tubes, and each of the support rings is welded to the contacting spiral tube.

[0009] By adopting the above technical solution, workers weld multiple support rings on the outer surface of the spiral tube in sequence. The support rings can connect multiple spiral tubes to form an integral structure, enhancing the overall rigidity of the multiple spiral tubes. At the same time, welding can ensure that the support rings are firmly connected to the spiral tube, reducing the probability of the support parts loosening or falling off, thereby further improving the support effect on the spiral tube, dispersing the gravity and radial stress borne by the middle section, and extending the service life of the spiral tube.

[0010] Optionally, the support member is a binding rope spirally wrapped around the outer surface of the spiral tube, and multiple binding ropes are all in contact with the outer surface of the spiral tube and have the same length and wrapping direction. A mounting post corresponding to the multiple binding ropes is provided between the two interface plates, and each mounting post is provided with a guide rope card and a welding plate. The guide rope card is provided with a limiting groove for limiting the binding rope, and the starting end of each binding rope is provided on the corresponding mounting post, and the free end passes through the guide rope card on the corresponding mounting post and is finally welded to the welding plate on the corresponding mounting post. The mounting post is provided with a tightening mechanism for adjusting the tightness of the multiple binding ropes.

[0011] By adopting the above technical solution, when laying out the binding ropes, each binding rope is first passed through the guide rope clamp of the corresponding mounting column, and then the binding rope is laid out on the outer surface of the spiral tube and finally welded to the welding clamp on the corresponding mounting column. After laying out, the worker adjusts the tightness of the binding rope through the tensioning mechanism, so that the binding rope is in contact with the outer surface of the spiral tube and is in a taut state, thereby achieving support for the spiral tube. Compared with the support method of welding support rings, the connection method of the binding rope does not require welding operation on the spiral tube, which can avoid welding damage to the spiral tube wall, and the tightness of the binding rope can be flexibly adjusted through the tensioning mechanism, which can adapt to the slight deformation of the spiral tube caused by thermal expansion and contraction or force changes during long-term use, thereby ensuring the supporting effect of the support member.

[0012] Optionally, the tensioning mechanism includes an elastic ring sleeved on the outer surfaces of the plurality of mounting posts, the starting end of each of the tying ropes being arranged on the elastic ring, the mounting post being provided with a convex strip along the axial direction, the elastic ring being provided with a sliding groove that slidably cooperates with the convex strip, the convex strip being provided with a plurality of locking grooves along the length direction, a receiving groove being provided on the inner side wall at one end of the sliding groove, and a plug-in groove being provided at the other end, a plug-in column that plugs into the plug-in groove being slidably connected in the receiving groove, and a control component being provided on the elastic ring, and when the elastic ring pulls the plurality of tying ropes to tighten, the control component drives the plug-in column to be inserted into the plug-in groove through the locking groove.

[0013] By adopting the above technical solution, after multiple binding ropes are welded, the worker pulls the elastic ring to slide on the convex strip. When the elastic ring moves, the starting end of the binding rope is pulled away from the end point, and the binding rope is gradually tightened and abuts against the outer surface of the spiral tube. Then the control component drives the plug-in column through the locking groove and inserts it into the plug-in groove, which can firmly lock the elastic ring in the current position, ensure the stability of the tightened state of the binding rope, and reduce the insufficient supporting force caused by looseness. The setting of the tensioning mechanism enables the tightness of the binding rope to adapt to the support requirements of the spiral tube under different stress states, thereby improving the applicability of the binding rope.

[0014] Optionally, the control assembly includes a connecting ring, a ring groove that rotatably cooperates with the connecting ring is provided in the elastic ring, an avoidance groove that is connected to the ring groove is provided on the inner side wall of the accommodating groove, a connecting frame is slidably connected to the inside of the avoidance groove, the connecting frame connects the plug-in column and the connecting ring, a shift block is provided on the connecting ring, a shift groove that slidably cooperates with the shift block is provided on the outer surface of the elastic ring, a threaded hole is provided at the end of the shift groove, and a fastening bolt that threadedly cooperates with the threaded hole is passed through the shift block.

[0015] By adopting the above technical solution, after the binding rope is tightened, the worker drives the connecting ring to rotate by turning the shift block, and the connecting ring drives the plug-in column to move toward the plug-in slot through the connecting frame. When the shift block abuts against the end of the shift slot, the plug-in column is inserted into the plug-in slot through the locking groove, thereby fixing the elastic ring on the mounting column. Finally, the worker screws the fastening bolt into the threaded hole to fix the shift block, preventing the connecting ring from accidentally rotating and causing the plug-in column to disengage from the plug-in slot, thereby ensuring the reliability of the locked state. The setting of the control component realizes the synchronous movement of multiple plug-in columns, making the locking and unlocking operations of the elastic ring simple and efficient.

[0016] Optionally, each of the mounting columns is provided with an adjusting rope card, and a plurality of limiting grooves are provided on the adjusting rope card and correspond one-to-one to the plurality of the binding ropes. The plurality of adjusting rope cards are arranged in sequence along the length direction of the spiral tube, and the free ends of the binding ropes pass through the corresponding limiting grooves on the plurality of adjusting rope cards in sequence and are welded to the welding plate.

[0017] By adopting the above technical solution, the binding rope is passed through multiple adjusting rope clamps in sequence to achieve the limitation of the binding rope, thereby reducing the entanglement or deviation of multiple binding ropes during the winding process, ensuring that each binding rope fits the outer surface of the spiral tube along the winding path preset by the adjusting rope clamp, thereby ensuring that the binding rope exerts a stable supporting force on the spiral tube, improving the stability of the spiral heat exchange tube and extending its service life.

[0018] Optionally, an adjustment groove is provided on the surface of the mounting column facing the spiral tube, the adjustment groove is parallel to the length direction of the mounting column, the adjustment rope clamp is slidably connected inside the adjustment groove, and the mounting column is provided with an adjustment component that drives the adjustment rope clamp to move along the length direction of the adjustment groove.

[0019] By adopting the above technical solution, when the adjustment component drives the adjustment rope clamp to move along the adjustment groove, the adjustment rope clamp drives multiple binding ropes to change the winding position synchronously, thereby realizing the adjustment of the winding path of the binding rope, so that the winding path of the binding rope avoids the gap between adjacent spiral tubes, reducing the probability of the binding rope losing its supporting force on the spiral tube due to being stuck in the gap of the spiral tube, expanding the contact area between the binding rope and the outer surface of the spiral tube, and ensuring that the supporting effect of the binding rope is stable and effective.

[0020] Optionally, the adjustment assembly includes a screw rotatably connected to the adjustment groove, a worm wheel is coaxially arranged at the end of the screw, a worm rotatably connected inside the adjustment groove and engaged with the worm wheel, and a rotating block is coaxially arranged at the end of the worm.

[0021] By adopting the above technical solution, when adjusting, the worker rotates the rotating block to drive the worm to rotate, and the worm and the worm wheel engage to drive the screw to rotate in the adjusting groove. Under the guide limit of the adjusting groove, the screw rotates to move the adjusting rope clamp, so that the winding path of the binding rope avoids the gap between adjacent spiral tubes, ensuring the supporting role of the binding rope. At the same time, the engagement of the worm wheel and the worm has a self-locking feature, which can firmly lock the adjusting rope clamp in the adjusted position, reducing the possibility of displacement of the adjusting rope clamp due to equipment vibration, etc., and improving the position stability of the adjusting rope clamp.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. This application provides a bent tube that bends toward the interface plate axis. The bent design shortens the distance between the outer end of the spiral tube and the interface plate axis, allowing the ends of multiple spiral tubes to connect to the interface plate within a smaller circumference, thereby reducing the overall size of the interface plate and making it occupy a smaller space. 2. This application provides multiple support members to form multiple sections of support along the length of the spiral tube, dispersing the gravity and radial stress borne by the middle section, thereby reducing the possibility of collapse and fracture of the spiral tube due to stress concentration in the middle section, and extending the service life of the spiral tube; 3. By providing a binding rope and a tensioning mechanism, the present application eliminates the need for welding the spiral tube, thus avoiding welding damage to the spiral tube wall. Furthermore, the tensioning mechanism allows for flexible adjustment of the binding rope's tightness, adapting to minor deformations of the spiral tube caused by thermal expansion and contraction or changes in force during long-term use, thereby ensuring the support function of the support member. 4. The present application sets an adjustment rope clamp and an adjustment component. When the adjustment component drives the adjustment rope clamp to move along the adjustment groove, the adjustment rope clamp drives multiple binding ropes to change the winding position synchronously, thereby adjusting the winding path of the binding rope, so that the winding path of the binding rope avoids the gap between adjacent spiral tubes, reducing the probability of the binding rope losing its supporting force on the spiral tube due to being stuck in the gap of the spiral tube, expanding the contact area between the binding rope and the outer surface of the spiral tube, and ensuring that the supporting effect of the binding rope is stable and effective.

DETAILED DESCRIPTION

[0031] The following is combined with Figure 1-7 This application is described in further detail.

[0032] The embodiment of the present application discloses a spiral heat exchange tube with good stability.

[0033] Example 1 Reference Figure 1 A spiral heat exchange tube with good stability includes two oppositely arranged interface plates 01, and multiple spiral tubes 02 are arranged between the two interface plates 01. The multiple spiral tubes 02 are distributed in sequence from the inside to the outside along the radial direction of the interface plate 01 to form multiple layers. Each layer is evenly distributed with multiple spiral tubes 02. The spiral directions of the spiral tubes 02 in each layer are consistent and a preset gap is left between adjacent layers. In this embodiment, a single-layer spiral tube 02 is taken as an example for explanation, and the multiple spiral tubes 02 in one layer are evenly distributed around the interface plate 01.

[0034] Reference Figure 1 Each spiral tube 02 is fixedly welded with a bent tube 1 at both ends along the length direction. The end of the bent tube 1 away from the spiral tube 02 is welded to the interface disk 01. The bending direction of the bent tube 1 is set toward the axis direction of the interface disk 01. The bending design of the bent tube 1 shortens the distance between the outer end of the spiral tube 02 and the axis of the interface disk 01, so that the ends of multiple spiral tubes 02 can be connected to the interface disk 01 within a smaller circumferential range, thereby reducing the overall size of the interface disk 01, so that the interface disk 01 occupies a smaller space.

[0035] Reference Figure 1, multiple support members 2 are commonly provided on the outer surfaces of multiple spiral tubes 02, and the support members 2 form multi-segment supports for the length direction of the spiral tubes 02, dispersing the gravity and radial stress borne by the middle section. In this embodiment, the support member 2 is a support ring 21 sleeved on the outer surfaces of the multiple spiral tubes 02. The number of support rings 21 is four, and the four support rings 21 are evenly arranged along the length direction of the spiral tubes 02. Each support ring 21 is welded to the contacting spiral tube 02. The use of welding can ensure that the support ring 21 is firmly connected to the spiral tube 02, reducing the probability of the support member 2 loosening or falling off.

[0036] The implementation principle of a spiral heat exchange tube with good stability in the embodiment of the present application is: the spiral tube 02 and the interface plate 01 are connected by a bending tube 1, so that the distance from the outer end of the spiral tube 02 to the axis of the interface plate 01 is shortened, so that the ends of multiple spiral tubes 02 can be connected to the interface plate 01 within a smaller circumferential range, reducing the overall size of the interface plate 01, so that the interface plate 01 occupies a smaller space, and at the same time, four support rings 21 are welded in sequence on the outer surface of the multiple spiral tubes 02. The support ring 21 can connect the multiple spiral tubes 02 to form an integral structure, enhance the overall rigidity of the multiple spiral tubes 02, and at the same time form multi-segment support for the length direction of the spiral tube 02, disperse the self-gravity and radial stress borne by the middle section, thereby reducing the possibility of collapse and fracture of the spiral tube 02 due to stress concentration in the middle section, and improving the service life of the spiral tube 02.

[0037] Example 2 Reference Figure 2 The difference between the embodiment of the present application and embodiment 1 is that the support member 2 is a binding rope 22 spirally wound around the outer surface of the spiral tube 02. In this embodiment, the number of the binding ropes 22 is four and they are stainless steel ropes. The four binding ropes 22 have the same length and are wound in the same direction.

[0038] Reference Figure 2 , a mounting post 3 corresponding to the four binding ropes 22 is fixedly installed between the two interface disks 01, and the four mounting posts 3 are evenly arranged along the circumference of the interface disk 01. A guide rope clamp 31, an adjusting rope clamp 32 and a welding plate 33 are fixedly connected to each mounting post 3 in sequence along the length direction. The guide rope clamp 31 and the welding plate 33 are located on both sides of the length direction of the spiral tube 02. Each guide rope clamp 31 and the adjusting rope clamp 32 are attached to the outer surface of the spiral tube 02. A limiting groove (not shown in the figure) is provided on the guide rope clamp 31, and four limiting grooves corresponding to the four binding ropes 22 are provided on the adjusting rope clamp 32. The limiting grooves on the guide rope clamp 31 and the adjusting rope clamp 32 are used to limit the binding rope 22, thereby reducing the entanglement or deviation of multiple binding ropes 22 during the winding process.

[0039] Reference Figure 2The four guide rope clips 31 and welding plates 33 on the four mounting columns 3 are evenly arranged along the length direction of the spiral tube 02. The spacing between the guide rope clips 31 and welding plates 33 on multiple mounting columns 3 is the same. The multiple adjustment rope clips 32 on different mounting columns 3 are arranged in sequence along the length direction of the spiral tube 02.

[0040] Reference Figure 2 and Figure 3 A tensioning mechanism 4 is provided on the mounting column 3. The tensioning mechanism 4 includes an elastic ring 41 slidably sleeved on the outer surface of the four mounting columns 3. The starting end of each tying rope 22 is welded to the elastic ring 41, and the free end passes through the guide rope clamp 31 on the corresponding mounting column 3, and then passes through the four adjusting rope clamps 32 in sequence and is finally welded to the welding plate 33 on the corresponding mounting column 3.

[0041] When winding the tying rope 22, first pass the free end of each tying rope 22 through the guide rope clamp 31 of the corresponding mounting column 3, and then sequentially pass multiple tying ropes 22 through the four adjustment rope clamps 32 in the same winding method. After the tying rope 22 is wound around the outer surface of the spiral tube 02 in multiple turns, the end of the tying rope 22 is welded to the welding clamp of the corresponding mounting column 3.

[0042] Reference Figure 2 、 Figure 4 and Figure 4 , the outer surface of the mounting column 3 away from the spiral tube 02 is fixedly connected with a convex strip 5, the convex strip 5 is parallel to the axial direction of the spiral tube 02, the elastic ring 41 is provided with a sliding groove 411 that slides with the convex strip 5, and the convex strip 5 is evenly and evenly provided with a plurality of locking grooves 51 along the length direction. The inner side wall of one end of the sliding groove 411 is provided with a receiving groove 412, and the other end is provided with a plug-in groove 413. When the elastic ring 41 moves to the locking groove 51 and the receiving groove 412 and the plug-in groove 413 When connected, the locking groove 51, the accommodating groove 412 and the plug-in groove 413 are connected to form an arc groove, the center of which is located on the axis of the interface disk 01, and the accommodating groove 412 is slidingly connected with a plug-in column 42 that is plugged into the plug-in groove 413. The curve of the plug-in column 42 is adapted to the arc groove connecting the locking groove 51, the accommodating groove 412 and the plug-in groove 413, and the elastic ring 41 is provided with a control component 43 that drives multiple plug-in columns 42 to move synchronously along the accommodating groove 412.

[0043] After the tying rope 22 is laid, the worker pulls the elastic ring 41 to slide in the direction of the convex strip 5 toward the welding clamp. When the elastic ring 41 moves, it pulls the starting end of the tying rope 22 away from the end point. The tying rope 22 is gradually tightened and abuts against the outer surface of the spiral tube 02. At this time, the tying rope 22 forms a support for the spiral tube 02 in the length direction. If the locking groove 51 and the accommodating groove 412 deviate slightly at this time, the worker continues to pull the elastic ring 41 toward the direction of the welding card to connect the accommodating groove 412 with the locking groove 51, and then uses the control component 43 to drive multiple plug-in columns 42 to move synchronously toward the locking groove 51. The plug-in column 42 is inserted into the plug-in groove 413 through the locking groove 51, so that the elastic ring 41 is fixed on the mounting column 3. This ensures the stability of the taut state of the binding rope 22 and reduces the insufficient supporting force caused by looseness. Compared with the support method of welding the support ring 21, the connection method of the binding rope 22 does not require welding operation on the spiral tube 02, which can avoid welding damage to the wall of the spiral tube 02, and the tightness of the binding rope 22 can be flexibly adjusted through the elastic mechanism 4, which can adapt to the slight deformation of the spiral tube 02 caused by thermal expansion and contraction or force changes during long-term use, thereby ensuring the supporting function of the support member 2.

[0044] Reference Figure 4 、 Figure 5 and Figure 6 The control assembly 43 includes a connecting ring 431, a ring groove 414 is provided in the elastic ring 41 and is rotatably matched with the connecting ring 431, and an avoidance groove 415 is provided on the inner wall of the accommodating groove 412 and is connected to the ring groove 414. A connecting frame 432 is slidably connected inside the avoidance groove 415. In this embodiment, the connecting frame 432 is L-shaped, and one end of the connecting frame 432 extends to the inside of the accommodating groove 412 and is fixedly connected to the plug-in column 42, and the other end extends to the inside of the ring groove 414 and is fixedly connected to the connecting ring 431.

[0045] Reference Figure 4 、 Figure 5 and Figure 6 A shift block 433 is fixedly connected to the connecting ring 431, and a shift groove 416 is provided on the outer surface of the elastic ring 41 facing away from the spiral tube 02, which is slidably matched with the shift block 433. A threaded hole is provided on the inner side wall of one end of the shift groove 416 (not shown in the figure), and a fastening bolt 434 is passed through the shift block 433 and threadedly matched with the threaded hole. When the shift block 433 is fixed by the fastening bolt 434, the plug-in column 42 is inserted into the plug-in groove 413.

[0046] After the binding rope 22 is tightened, the worker moves the shift block 433 in the shift slot 416 to drive the connecting ring 431 to rotate. The connecting ring 431 drives the plug-in column 42 to move toward the plug-in slot 413 through the connecting frame 432. When the shift block 433 abuts against the end of the shift slot 416, the plug-in column 42 is inserted into the plug-in slot 413 through the locking slot 51, thereby fixing the elastic ring 41 on the mounting column 3. Finally, the worker screws the fastening bolt 434 into the threaded hole to fix the shift block 433, preventing the connecting ring 431 from accidentally rotating and causing the plug-in column 42 to disengage from the plug-in slot 413, thereby ensuring the reliability of the locked state.

[0047] Reference Figure 2 and Figure 7 During the installation process, there is a situation where a single or multiple tying ropes 22 are embedded in the gap of the spiral tube 02. At this time, the tying rope 22 cannot abut against the outer surface of the spiral tube 02, causing the supporting function of the tying rope 22 to fail, so that the middle section of the spiral tube 02 still bears its own gravity and radial stress.

[0048] In order to solve the above technical problems, an adjustment groove 34 is opened on the surface of the mounting column 3 facing the spiral tube 02. The adjustment groove 34 is parallel to the length direction of the mounting column 3. The adjustment rope clamp 32 is slidably connected to the inside of the adjustment groove 34. In this embodiment, the adjustment rope clamp 32 is fixedly connected to a guide block (not shown in the figure) that slides with the adjustment groove 34. The cross-sectional shape of the adjustment groove 34 and the guide block is T-shaped.

[0049] Reference Figure 2 and Figure 7 Each mounting column 3 is provided with an adjustment assembly 6, which includes a screw 61 rotatably connected to the adjustment slot 34, the end of the screw 61 is coaxially fixedly connected to a worm gear 62, a worm 63 rotatably connected to the inside of the adjustment slot 34 and engaged with the worm gear 62, the end of the worm 63 is coaxially fixedly connected to a rotating block 64, the rotating block 64 adopts an embedded design and is provided with an inner hexagonal hole (not shown in the figure) for easy rotation.

[0050] When the tying rope 22 is stuck in the gap after being laid, the worker rotates the rotating block 64 to drive the worm 63 to rotate, and the worm 63 engages with the worm wheel 62 to drive the screw 61 to rotate in the adjusting groove 34. Under the guide limit of the adjusting groove 34, the screw 61 rotates to move the adjusting rope clamp 32, and the adjusting rope clamp 32 drives multiple tying ropes 22 to synchronously change the laying position until the laying path of the tying rope 22 avoids the gap between adjacent spiral tubes 02, thereby reducing the probability of the tying rope 22 losing its supporting force on the spiral tube 02 due to being stuck in the gap of the spiral tube 02, expanding the contact area between the tying rope 22 and the outer surface of the spiral tube 02, and ensuring that the supporting function of the tying rope 22 is stable and effective.

[0051] The implementation principle of Example 2 is as follows: before bundling, the position of the adjusting rope clamp 32 is changed by the adjusting assembly 6 so that the adjusting rope clamp 32 guides the winding path of the tying rope 22 to the outside of the gap, and then the free end of each tying rope 22 is passed through the guide rope clamp 31 of the corresponding mounting post 3. Then, multiple tying ropes 22 are sequentially passed through the inside of the four adjusting rope clamps 32 in the same winding manner. After the tying rope 22 is wound around the outer surface of the spiral tube 02 in multiple turns, the end of the tying rope 22 is welded to the welding clamp of the corresponding mounting post 3; After welding is completed, the tightness of the binding rope 22 is adjusted through the tensioning mechanism 4, so that the binding rope 22 is in a taut state against the outer surface of the spiral tube 02, thereby achieving support for the spiral tube 02. Compared with the support method of the welding support ring 21, the connection method of the binding rope 22 does not require welding operation on the spiral tube 02, which can avoid welding damage to the wall of the spiral tube 02. The tightness of the binding rope 22 can be flexibly adjusted through the tensioning mechanism 4, which can adapt to the slight deformation of the spiral tube 02 caused by thermal expansion and contraction or force changes during long-term use, thereby ensuring the supporting function of the support member 2.

[0052] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
