Description

Technical Field

[0001] The present invention relates to the field of high-throughput tube processing equipment, and in particular to a high-throughput tube surface processing device and a processing method thereof. Background Art

[0002] A high-throughput tube is a heat exchange tube with high-efficiency heat transfer used in a heat exchanger. A porous powder metal layer is sintered on the inner surface of the tube, and longitudinal grooves are processed on the outer surface of the tube. The heat transfer area is increased through the structure of the longitudinal grooves to achieve the purpose of improving the heat transfer efficiency.

[0003] The outside of the tube is heated with steam to evaporate the moisture of the working medium inside the tube. The purpose of grooving on the outside of the tube is to increase the heat transfer area. More importantly, it allows the cooled liquid to drain away, enables the steam to directly heat the outside of the tube, and improves the evaporation efficiency of the working medium inside the tube.

[0004] The medium flow rate in the longitudinal grooves is relatively fast and the residence time is relatively short; at the same time, the medium in the longitudinal grooves flows smoothly, and the medium in the longitudinal grooves and the medium outside the high-throughput tube cannot form effective heat transfer; as a result, the improvement of the heat transfer efficiency by the longitudinal grooves on the high-throughput tube is limited.

[0005] It should be noted that the information disclosed in the above background art section is only used to enhance the understanding of the background of the present disclosure, and thus may include information that does not constitute the prior art known to those of ordinary skill in the art. Summary of the Invention

[0006] Aiming at the above-mentioned shortcomings of the prior art, the purpose of the present invention is to provide a high-throughput tube surface processing device and a processing method thereof, so as to solve the problems in the prior art that the medium flow rate in the longitudinal grooves is relatively fast and the residence time is relatively short; at the same time, the medium in the longitudinal grooves flows smoothly, and the two media cannot form effective heat transfer, resulting in limited improvement of the heat transfer efficiency by the longitudinal grooves on the high-throughput tube.

[0007] To achieve the above purpose, the technical solution of the present invention is as follows:

[0008] A high-throughput tube surface processing device;

[0009] It includes: a bracket; a clamping block arranged on the bracket around the high-throughput tube; a groove block rotatably connected to the clamping block; a driving wheel set rotatably arranged on the bracket; a driving mechanism arranged on the bracket to drive the clamping block to reciprocate closer to or away from each other.

[0010] Wherein, when the driving mechanism drives the clamping blocks to approach each other, the clamping blocks clamp the high-throughput tube and push the high-throughput tube to move; when the driving mechanism drives the clamping blocks to move away from each other, the clamping blocks disengage from the high-throughput tube; the driving wheel set contacts and drives the high-throughput tube to rotate by a certain angle, changing the processing path on the surface of the high-throughput tube; when the clamping blocks clamp the high-throughput tube, the groove block presses into the surface of the high-throughput tube and forms a processing mark.

[0011] A further technical solution is that a clamping path is formed inside the bracket; the clamping path forms a closed loop, and the clamping block moves along the clamping path, so that the clamping block reciprocally approaches or moves away.

[0012] A further technical solution is that a space is formed inside the clamping block, and a piston is slidably arranged in the space; a turntable is rotatably arranged on the clamping block; the turntable meshes with the piston; the space communicates with an air source; the groove block is arranged on the turntable.

[0013] A further technical solution is that the driving wheel set includes a supporting wheel for rolling and supporting a high-flux tube, an adjusting wheel for contacting and driving the high-flux tube to rotate, and a first power device arranged on the bracket; wherein, the first power device drives the adjusting wheel to rotate, and the adjusting wheel drives the high-flux tube to rotate.

[0014] A further technical solution is that the driving mechanism includes: an annular plate, an annular cylinder, plate rods arranged side by side on the annular plate, and cylinder spaces formed side by side inside the annular cylinder; wherein, the plate rods are slidably arranged in the cylinder spaces; the clamping blocks are slidably arranged on the annular plate; the cylinder spaces communicate with an air source. <s

[0015] A further technical solution is that a moving device is further included; the moving device includes a clamping ring for clamping a high-flux tube, a moving plate for pulling the high-flux tube, and a guide rail arranged along the moving direction of the high-flux tube; wherein, the moving plate moves along the guide rail; the clamping ring is rotatably arranged on the moving plate.

[0016] A processing method of a high-flux tube surface processing device includes the following steps:

[0017] Analysis step: According to the heat exchange situation of the medium, the tube grooves on the surface of the high-flux tube are divided into linear tube grooves and spiral tube grooves; determine the type data of the tube grooves and the distribution data of the tube grooves; the spiral tube grooves include: spiral angle data and spiral direction data;

[0018] The processing step includes a linear tube groove processing process and a spiral tube groove processing process, and combines the linear tube groove processing process and the spiral tube groove processing process according to the data in the analysis step:

[0019] Linear tube groove processing process: The clamping block moves along the clamping path; the clamping blocks approach each other to clamp the high-flux tube, and the groove block extrudes the high-flux tube to form a linear tube groove on the surface of the high-flux tube, the clamping block pushes the high-flux tube to move axially, the clamping blocks move away from each other to disengage from the high-flux tube, and the clamping block moves axially to reset;

[0020] Spiral tube groove processing process: An air source is introduced into the space, the piston moves along the space, and the piston drives the turntable and the groove block to rotate by a certain angle;

[0021] The clamping blocks move along the clamping path; the clamping blocks approach each other to clamp the high-flux tube, and the groove block squeezes the high-flux tube to form spiral tube grooves on the surface of the high-flux tube. The clamping blocks push the high-flux tube to move axially. The first power device drives the adjusting wheel to rotate, and the adjusting wheel drives the high-flux tube to rotate a certain angle. The clamping blocks move away from each other and disengage from the high-flux tube, and the clamping blocks move axially to reset.

[0022] A further technical solution is that the processing step further includes a stabilizing process: the clamping ring clamps the high-flux tube; according to the rotation angle of the high-flux tube, the clamping ring drives the high-flux tube to rotate a corresponding angle; according to the moving distance of the high-flux tube, the moving plate drives the high-flux tube to move a corresponding distance.

[0023] Compared with the prior art, the beneficial technical effects of the present invention are as follows: (1) The driving mechanism drives the clamping blocks to move reciprocally, and the clamping blocks repeatedly approach the high-flux tube, so that the groove block extrudes the tube grooves. After the clamping blocks push the high-flux tube to move a certain distance and then reset, continuous tube grooves can be realized on the high-flux tube; by rotating the groove block along the clamping block by a certain angle, the groove block can extrude straight tube grooves and inclined tube grooves at different angles, so that the continuous tube grooves can be distributed to form straight tube grooves and inclined tube grooves at different angles to control the flow direction and flow rate of the medium in the tube grooves, so that the medium in the tube grooves flows spirally and collides with the medium outside the high-flux tube to form eddy currents, resulting in heat exchange and improving the heat exchange efficiency; when switching between tube grooves in different states, the medium in the tube grooves collides and splashes and exchanges heat with the medium outside the high-flux tube, improving the heat exchange efficiency.

[0024] (2) In the moving-out direction of the high-flux tube, the first power device drives the adjusting wheel to rotate, the wheel rod is embedded in the tube groove, and the adjusting wheel drives the high-flux tube to rotate through the friction force between the adjusting wheel and the high-flux tube. The wheel rod drives the high-flux tube to rotate by contacting and pushing the tube groove; it avoids slipping between the adjusting wheel and the high-flux tube, which may cause the inability to form continuous processing marks; in the moving-in direction of the high-flux tube, the high-flux tube does not form tube grooves, and the adjusting wheel drives the high-flux tube to rotate through the friction force between the adjusting wheel and the high-flux tube, reducing the burden on the adjusting wheel in the moving-out direction of the high-flux tube, and ensuring the stability of the high-flux rotation through two sets of driving wheel sets.

[0025] (3) The driving wheel set drives the high-throughput tube to rotate by a certain angle, so that the groove block can form an inclined tube groove. Since the high-throughput tube is relatively long, when a certain position of the high-throughput tube rotates, it will drive the whole high-throughput tube to rotate. Due to the heavy self-weight of the high-throughput tube, torsional deformation will occur at the position far from the rotation on the high-throughput tube. At the same time, during the process of forming processing marks on the high-throughput tube, the distance that the high-throughput tube moves each time is relatively short, and during the process of the groove block pressing into the surface of the high-throughput tube and moving out of the tube groove, it will cause the high-throughput tube to vibrate. The two ends of the high-throughput tube are clamped by the clamping ring to prevent the high-throughput tube from vibrating. The moving plate moves along the guide rail, so that the high-throughput tube moves as a whole during the processing process, avoiding the resistance caused by the self-weight of the high-throughput tube to the clamping block pushing the high-throughput tube to move. The clamping ring rotates along the moving plate, so that the high-throughput tube can rotate as a whole during the rotation process, avoiding torsional deformation.

Therefore, they do not have technical substantial significance.

[0033] Figure 1 Fig. 1 shows a schematic structural diagram of a high-throughput tube surface processing device according to a first embodiment of the present invention. Figure 2 Fig. 1 shows Figure 1 an enlarged structural diagram at position A in Fig. 1. In combination with Figure 1 and Figure 2 shown in Fig. 2, the present invention discloses a high-throughput tube surface processing device.

[0034] The high-throughput tube surface processing device includes: a driving mechanism 5, a bracket 1, a clamping block 2 arranged on the bracket 1 around the high-throughput tube, a groove block 3 rotatably connected to the clamping block 2, and a driving wheel set 4 rotatably arranged on the bracket 1.

[0035] Among them, the driving mechanism 5 is arranged on the bracket 1 to drive the clamping block 2 to reciprocate close to or away from each other. The driving mechanism 5 drives the clamping blocks 2 to approach each other, and the clamping blocks 2 clamp the high-throughput tube and push the high-throughput tube to move. When the clamping blocks 2 clamp the high-throughput tube, the groove block 3 presses into the surface of the high-throughput tube and forms a processing mark. The driving mechanism 5 drives the clamping blocks 2 to move away from each other, and the clamping blocks 2 disengage from the high-throughput tube.

[0036] Exemplarily, there are multiple groups of clamping blocks 2. Exemplarily, the processing mark is a tube groove. When the clamping blocks 2 clamp the high-throughput tube, the clamping blocks 2 contact the outer surface of the high-throughput tube, and the groove block 3 presses into the high-throughput tube to form a tube groove in the high-throughput tube, and the groove block 3 contacts the inner surface of the tube groove.

[0037] The driving wheel set 4 contacts and drives the high-throughput tube to rotate by a certain angle, changing the processing path on the surface of the high-throughput tube. When the groove block 3 rotates to an inclined state, the tube groove formed by the groove block 3 pressing into the high-throughput tube is inclined. To ensure the continuity of the tube groove. After machining a tube groove, the high-throughput tube needs to be rotated by a certain angle before machining the next tube groove.

[0038] The clamping block 2 is driven by a driving mechanism 5 to move reciprocally. The clamping block 2 repeatedly approaches the high-flux tube in a cyclic manner, causing the groove block 3 to extrude a tube groove. After the clamping block 2 pushes the high-flux tube to move a certain distance and then resets, continuous tube grooves can be formed on the high-flux tube. By rotating the groove block 3 at a certain angle along the clamping block 2, the groove block 3 can extrude linear tube grooves and inclined tube grooves at different angles, so that the continuous tube grooves can be distributed to form linear tube grooves and inclined tube grooves at different angles, in order to control the flow direction and flow rate of the medium in the tube grooves, making the medium in the tube grooves flow in a spiral manner and collide with the medium outside the high-flux tube to form eddies, resulting in heat exchange and improving the heat exchange efficiency. When switching between tube grooves in different states, the medium in the tube grooves collides and splashes and exchanges heat with the medium outside the high-flux tube, improving the heat exchange efficiency.

[0039] A clamping path 12 is formed inside the bracket 1. The clamping path 12 forms a closed loop, and the clamping block 2 moves along the clamping path 12, causing the clamping block 2 to approach or move away reciprocally.

[0040] The clamping path 12 includes a moving section 121, a separating section 122, a reset section 123, and an approaching section 124 that are connected in sequence. The moving section 121 and the reset section 123 are parallel to each other, and the separating section 122 and the approaching section 124 are parallel to each other. When the clamping block 2 moves along the approaching section 124, the clamping blocks 2 approach each other to clamp the high-flux tube. When the clamping block 2 moves along the moving section 121, the clamping block 2 pushes the high-flux tube to move. When the clamping block 2 moves along the separating section 122, the clamping blocks 2 move away from each other to disengage from the high-flux tube. When the clamping block 2 moves along the reset section 123, the clamping block 2 moves back to its original position. The clamping block 2 moves along the clamping path 12, and the clamping block 2 reciprocally clamps and pushes the high-flux tube to move.

[0041] A block rod 24 is provided on the clamping block 2, and a roller 25 is rotatably provided on the block rod 24. The roller 25 rolls along the clamping path 12 to complete the reciprocating clamping and pushing of the high-flux tube by the clamping block 2.

[0042] Figure 3 The schematic top view structure of the clamping block in the first embodiment of the present invention is shown. In combination with Figures 1-3 As shown, two groups of spaces 21 are formed at intervals inside the clamping block 2, and pistons 22 are slidably provided inside the spaces 21. A turntable 23 is rotatably provided on the clamping block 2, and the turntable 23 is located between adjacent spaces 21. Tooth shapes are respectively formed on the pistons 22 and the turntable 23, so that the turntable 23 meshes with the pistons 22. The spaces 21 are connected to a gas source. The groove block 3 is provided on the turntable 23.

[0043] The two sets of spaces 21 each intake and exhaust air, causing the pistons 22 in the two sets of spaces 21 to reciprocate and stagger, thereby driving the rotation of the turntable 23 and the tank block 3. By controlling the amount of air intake and exhaust, the rotation angle of the tank block 3 can be controlled. When one set of spaces 21 intakes air and the other set of spaces 21 exhausts air, the tank block 3 rotates clockwise. When the other set of spaces 21 intakes air and the other set of spaces 21 exhausts air, the tank block 3 rotates counterclockwise.

[0044] The driving wheel assembly 4 includes a supporting wheel 41 for rolling support of the high-flux tube, an adjusting wheel 42 for contact-driving the high-flux tube to rotate, and a first power device 43 provided on the bracket 1 .

[0045] Exemplarily, there are two sets of drive wheel assemblies 4, one located on either side of the bracket 1. Exemplarily, there are multiple sets of support wheels 41. These support wheels 41 are positioned below the high-flux tubes and are staggered relative to each other. The outer surfaces of the support wheels 41 are conical, allowing the high-flux tubes to rest on the conical surfaces of the support wheels 41.

[0046] Figure 4 FIG1 shows a schematic structural diagram of the adjustment wheel according to the first embodiment of the present invention. Figures 1-4 As shown, the first power device 43 is exemplarily a motor. A rod 421 is slidably disposed around the adjustment wheel 42 in the direction of removal of the high-flux tube. A first elastic device 422 is sleeved on the rod 421. The first elastic device 422 extends to push the rod 421 out of the adjustment wheel 42, whereupon the rod 421 engages the tube groove. When the rod 421 contacts the outer surface of the high-flux tube, the rod 421 moves into the adjustment wheel 42, and the first elastic device 422 contracts.

[0047] In the removal direction of the high-flux tube, the first power device 43 drives the adjustment wheel 42 to rotate, and the wheel rod 421 engages the tube groove. The adjustment wheel 42 drives the high-flux tube through friction with the high-flux tube, and the wheel rod 421 drives the high-flux tube by contacting and pushing the tube groove. This prevents slippage between the adjustment wheel 42 and the high-flux tube, which prevents the formation of continuous processing marks.

[0048] In the moving-in direction of the high-flux tube, no tube groove is formed in the high-flux tube. The adjusting wheel 42 drives the high-flux tube to rotate through the friction between the adjusting wheel 42 and the high-flux tube, thereby reducing the burden of the adjusting wheel 42 in the moving-out direction of the high-flux tube. The stability of the high-flux rotation is ensured by the two sets of driving wheel groups 4.

[0049] Figure 5 FIG1 shows a schematic diagram of the structure of the driving mechanism of the first embodiment of the present invention. Figures 1-5 As shown, the driving mechanism 5 includes: an annular plate 51 , an annular cylinder 52 , plate rods 53 arranged in parallel on the annular plate 51 , and a cylinder space 54 formed in parallel in the annular cylinder 52 .

[0050] A step 531 is formed in the middle of the plate rod 53, and the plate rod 53 is slidably arranged in the cylinder space 54. The step 531 is placed in the cylinder space 54 and contacts the inner surface of the cylinder space 54. The cylinder spaces 54 are formed in the annular cylinder 52 in the left and right directions, and the cylinder spaces 54 are distributed in parallel around the annular cylinder 52.

[0051] The clamping block 2 is slidably arranged on the ring plate 51 . A plate groove 511 is formed on the ring plate 51 . The clamping block 2 is placed in the plate groove 511 . A second elastic device 512 is placed in the plate groove 511 . The second elastic device 512 elastically presses the clamping block 2 .

[0052] The cylinder space 54 is connected to a gas source. Gas entering the cylinder space 54 pushes the step 531, causing the plate rod 53 to move along the annular cylinder 52, driving the annular plate 51 to move axially and the clamping block 2 to move along the clamping path 12. When the clamping blocks 2 move toward or away from each other, they move along the plate groove 511. The second elastic device 512 provides elastic thrust, ensuring smooth movement of the clamping blocks 2.

[0053] The high-flux tube surface processing apparatus also includes a moving device 6. This device comprises a clamping ring 61 for clamping the high-flux tube, a moving plate 62 for pulling the high-flux tube, and a guide rail 63 arranged along the moving direction of the high-flux tube. The moving plate 62 moves along the guide rail 63. The clamping ring 61 is rotatably mounted on the moving plate 62.

[0054] A first clamping plate 611 is fixedly mounted on one side of the clamping ring 61, and a second clamping plate 612 is slidably mounted on the other side of the clamping ring 61. A first raised ring 613 is mounted on the first clamping plate 611, and a second raised ring 614 is mounted on the second clamping plate 612. A magnetic device 615 is mounted on the first clamping plate 611, which magnetically attracts the second clamping plate 612. The second clamping plate 612 is brought closer to the first clamping plate 611, and the first and second raised rings 613 and 614 clamp the high-flux tube.

[0055] The diameter of the first convex ring 613 is smaller than that of the second convex ring 614, and the inner ring of the second convex ring 614 forms convex parts in parallel, so that when the first convex ring 613 and the second convex ring 614 clamp the high-flux tube, the convex part of the second convex ring 614 is embedded in the tube groove on the outer surface of the high-flux tube, so that the first convex ring 613 and the second convex ring 614 can completely and firmly clamp the high-flux tube to prevent the high-flux tube from slipping axially or radially.

[0056] Guide rail 63 is arranged for left and right directions. Travel wheel 64 and second power unit 65 are arranged below movable plate 62. Second power unit 65 drives travel wheel 64 to roll along guide rail 63, makes movable plate 62 move along guide rail 63.

[0057] A rack 616 is arranged around the clamping ring 61, and a third power device 66 is arranged above the moving plate 62. A gear 67 is arranged at the driving end of the third power device 66. The gear 67 meshes with the rack 616. By driving the gear 67 to rotate through the third power device 66, the gear 67 drives the clamping ring 61 to rotate through meshing with the rack 616, thereby driving the high-flux tube to rotate.

[0058] The driving wheel set 4 drives the high-flux to rotate by a certain angle, so that the groove block 3 can form a slanted pipe groove. Since the high-flux tube is relatively long, when a certain position of the high-flux tube rotates, it will drive the entire high-flux tube to rotate. Due to the heavy self-weight of the high-flux tube, torsional deformation will occur at the position far from the rotation on the high-flux tube. At the same time, since the high-flux tube forms processing marks, the single movement distance of the high-flux tube is short, and the high-flux tube will vibrate during the process of the groove block 3 being pressed into the surface of the high-flux tube and being removed from the pipe groove.

[0059] The two ends of the high-flux tube are clamped by the clamping ring 61 to prevent the high-flux tube from vibrating. The moving plate 62 moves along the guide rail 63, so that the high-flux tube moves integrally during the processing process, avoiding the resistance caused by the self-weight of the high-flux tube to the movement of the clamping block 2 pushing the high-flux tube. The clamping ring 61 rotates along the moving plate 62, so that the high-flux tube rotates integrally during the rotation process, avoiding torsional deformation.

[0060] Second Embodiment:

[0061] The processing method of the high-flux tube surface processing device includes the following steps:

[0062] Analysis step: According to the heat exchange situation of the medium, the tube grooves on the surface of the high-flux tube are divided into linear tube grooves and spiral tube grooves. Determine the type data of the tube grooves and the distribution data of the tube grooves. The spiral tube grooves include: spiral angle data and spiral direction data.

[0063] According to the heat exchange situation of the medium, the tube grooves on the surface of the high-flux tube can be linear tube grooves, spiral tube grooves with the same direction angle, spiral tube grooves with the same direction but different angles, spiral tube grooves with different direction angles alternating, linear tube grooves and spiral tube grooves alternating, etc.

[0064] When the tube grooves on the surface of the high-flux tube are spiral tube grooves with the same direction angle: there are two groups of flow paths when the medium flows along the outside of the high-flux tube. One group of medium flows spirally along the spiral tube grooves, and the other group of medium flows linearly along the outer surface of the high-flux tube. Compared with the linear tube grooves, the spiral tube grooves increase the flow time of the medium. The two groups of media with different flow rates and different heating temperatures collide and contact with each other to form eddy currents, completing the mixing between the two groups of media and improving the heat exchange efficiency of the medium.

[0065] When the tube grooves on the surface of the high-flux tube are spiral tube grooves with the same direction but different angles: When the medium flows along the outside of the high-flux tube, there are two sets of flow paths. One set of the medium flows spirally along the spiral tube grooves, and the other set of the medium flows linearly along the outer surface of the high-flux tube. According to the different structures of the heat exchanger, there are changes in the flow velocity of the other set of the medium flowing along the outer surface of the high-flux tube. When the flow velocity of the other set of the medium is relatively fast, the angle between the spiral tube grooves and the edge of the high-flux tube is relatively small. When the flow velocity of the other set of the medium is relatively slow, the angle between the spiral tube grooves and the edge of the high-flux tube is relatively large.

[0066] When the tube grooves on the surface of the high-flux tube are formed by alternating spiral tube grooves with different direction angles: When the medium flows along the outside of the high-flux tube, there are two sets of flow paths. One set of the medium flows alternately in a clockwise spiral and a counterclockwise spiral along the spiral tube grooves, and the other set of the medium flows linearly along the outer surface of the high-flux tube. When one set of the medium flows to the alternating position, it collides and splashes, causing the flow velocity of one set of the medium to rapidly slow down, increasing the flow time of one set of the medium and improving the heat exchange efficiency of the medium. At the same time, one set of the medium splashes, causing one set of the medium and the other set of the medium to come into contact and mix with each other, improving the heat exchange efficiency of the medium.

[0067] When the tube grooves on the surface of the high-flux tube are formed by alternating linear tube grooves and spiral tube grooves: When the medium flows along the outside of the high-flux tube, there are two sets of flow paths. One set of the medium flows spirally along the spiral tube grooves or linearly along the linear tube grooves, and the other set of the medium flows linearly along the outer surface of the high-flux tube. When one set of the medium flows linearly along the linear tube grooves, the flow velocities of the two sets of the medium are the same and no eddy current is generated. At the positions of the high-flux tube close to the tube sheet, sensors and other auxiliary devices, it is necessary to ensure that they are not disturbed by the eddy current, so the tube grooves at this position are linear tube grooves.

[0068] Send the type data of the tube grooves, the distribution data of the tube grooves, the spiral angle data and the spiral direction data to the controller corresponding to the clamping block 2 to control the rotation direction and rotation angle of the groove block 3, and the controller corresponding to the driving wheel set 4 to control the start-stop and output power of the first power device 43, and the controller corresponding to the driving mechanism 5 to control the driving frequency of the driving mechanism 5.

[0069] The processing steps include the processing process of the linear tube grooves and the processing process of the spiral tube grooves, and combine the processing process of the linear tube grooves and the processing process of the spiral tube grooves according to the data in the analysis steps:
