Description

Technical Field

[0001] The 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] High flux tube is a heat exchange tube with high efficiency heat transfer used in heat exchangers. High flux tube is a tube with porous powder metal layer sintered on the inner surface of the tube. High flux tube is a tube with longitudinal grooves processed on the outer surface of the tube. The heat exchange area is increased through the longitudinal groove structure to achieve the purpose of improving heat exchange efficiency.

[0003] The outside of the tube is heated with steam to evaporate the water in the working fluid inside the tube. The purpose of the grooves on the outside of the tube is to increase the heat exchange area. More importantly, it allows the cooled liquid to drain away, allowing the steam to directly heat the outside of the tube and improve the evaporation efficiency of the working fluid in the tube.

[0004] The medium in the longitudinal groove has a fast flow rate and a short residence time; at the same time, the medium in the longitudinal groove flows smoothly, and the medium in the longitudinal groove and the medium outside the high-flux tube cannot form effective heat exchange; this makes the longitudinal groove on the high-flux tube have limited improvement in heat exchange efficiency.

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

[0006] In view of the shortcomings of the above-mentioned prior art, the purpose of the present invention is to provide a high-flux tube surface processing device and a processing method thereof, so as to solve the problem in the prior art that the medium flow rate in the longitudinal groove is fast and the residence time is short; at the same time, the medium flows smoothly in the longitudinal groove, and the two media cannot form effective heat exchange, which makes the longitudinal groove on the high-flux tube have limited improvement on the heat exchange efficiency.

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

[0011] A further technical solution is that a clamping path is formed in the bracket; the clamping path forms a closed loop, and the clamping block moves along the clamping path so that the clamping block reciprocates to move closer or farther away.

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

[0013] A further technical solution is that the driving wheel group includes a supporting wheel for rollingly supporting the high-flux tube, an adjusting wheel for contact-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: a ring plate, a ring cylinder, plate rods arranged in parallel on the ring plate and a cylinder space formed in parallel in the ring cylinder; wherein the plate rods are slidably arranged in the cylinder space; the clamping block is slidably arranged on the ring plate; and the cylinder space is connected to an air source.

[0015] A further technical solution is that it also includes a moving device; the moving device includes a clamping ring for clamping the 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; and the clamping ring is rotatably arranged on the moving plate.

[0016] A processing method for a high-throughput tube surface processing device comprises the following steps:

[0017] Analysis steps: according to the heat transfer of the medium, the surface grooves of the high-flux tube are divided into linear grooves and spiral grooves; the type data and distribution data of the grooves are determined; the spiral grooves include: spiral angle data and spiral direction data;

[0018] The processing steps include a straight pipe groove processing process and a spiral pipe groove processing process. The straight pipe groove processing process and the spiral pipe groove processing process are combined according to the data in the analysis step:

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

[0020] Processing process of spiral pipe groove: the 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 a certain angle;

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

[0022] A further technical solution is that the processing steps also include a stabilization 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 clamping block is driven to move back and forth by the driving mechanism, and the clamping block repeatedly cycles close to the high-flux tube, so that the slot block squeezes out the tube slot, and the clamping block pushes the high-flux tube to move a certain distance and then resets, so that continuous tube slots can be realized on the high-flux tube; the slot block is rotated along the clamping block by a certain angle, so that the slot block can squeeze out straight tube slots and inclined tube slots of different angles, so that continuous tube slots can be distributed to form straight tube slots and inclined tube slots of different angles, so as to control the flow direction and flow rate of the medium in the tube slot, so that the medium in the tube slot flows in a spiral manner and collides with the medium outside the high-flux tube to form a vortex, heat exchange occurs, and heat exchange efficiency is improved; when the tube slots in different states are switched, the medium in the tube slot collides and splashes and heat exchange occurs with the medium outside the high-flux tube, so as to improve the heat exchange efficiency.

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

[0025] (3) The driving wheel assembly drives the high-flux tube to rotate at a certain angle, so that the slot block can form an inclined tube slot. Since the high-flux tube is long, when a certain position of the high-flux tube rotates, it will drive the high-flux tube to rotate as a whole. Since the high-flux tube has a heavy weight, a torsional deformation will occur at a position far away from the rotation on the high-flux tube. At the same time, since the high-flux tube moves a short distance at a time in the process of forming processing marks, and the slot block presses into the surface of the high-flux tube and moves out of the tube slot, it will cause the high-flux tube to shake. The clamp ring clamps the two ends of the high-flux tube to prevent the high-flux tube from shaking. The moving plate moves along the guide rail so that the high-flux tube moves as a whole during the processing process, avoiding the self-weight of the high-flux tube from forming resistance to the clamping block pushing the high-flux tube to move. The clamp ring rotates along the moving plate so that the high-flux tube rotates as a whole during the rotation process, avoiding torsional deformation. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] In order to make the purpose, technical scheme and advantages of the present invention clearer, the device proposed by the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. According to the following description, the advantages and features of the present invention will be clearer.

Any modification of the structure, change of the proportional relationship or adjustment of the size, without affecting the effect that the present invention can produce and the purpose that can be achieved, should still fall within the scope of the technical content disclosed by the present invention.

[0033] Figure 1 The schematic diagram of the structure of the high-flux tube surface processing device according to the first embodiment of the present invention is shown. Figure 2 Shows Figure 1 The enlarged structure diagram of A in the middle. Figure 1 and Figure 2 As shown, the present invention discloses a high-throughput tube surface processing device.

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

[0035] The driving mechanism 5 is arranged on the bracket 1 to drive the clamping blocks 2 to move back and forth. The driving mechanism 5 drives the clamping blocks 2 to move closer to each other, and the clamping blocks 2 clamp the high-flux tube and push the high-flux tube to move. When the clamping blocks 2 clamp the high-flux tube, the groove blocks 3 press into the surface of the high-flux tube and form processing marks. The driving mechanism 5 drives the clamping blocks 2 to move away from each other, and the clamping blocks 2 are separated from the high-flux tube.

[0036] Exemplarily, the clamping blocks 2 are in multiple groups. Exemplarily, the processing traces are tube grooves. When the clamping blocks 2 clamp the high-flux tube, the clamping blocks 2 contact the outer surface of the high-flux tube, the groove blocks 3 are pressed into the high-flux tube to form a tube groove in the high-flux tube, and the groove blocks 3 contact the inner surface of the tube groove.

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

[0038] The clamping block 2 is driven to move back and forth by the driving mechanism 5, and the clamping block 2 repeatedly cycles close to the high-flux tube, so that the slot block 3 squeezes out the tube slot, and the clamping block 2 pushes the high-flux tube to move a certain distance and then resets, so that continuous tube slots can be realized on the high-flux tube. The slot block 3 rotates a certain angle along the clamping block 2, so that the slot block 3 can squeeze out straight tube slots and inclined tube slots at different angles, so that continuous tube slots can be distributed to form straight tube slots and inclined tube slots at different angles, so as to control the flow direction and flow rate of the medium in the tube slot, so that the medium in the tube slot flows in a spiral and collides with the medium outside the high-flux tube to form a vortex, so that heat exchange occurs, and the heat exchange efficiency is improved. When the tube slots in different states are switched, the medium in the tube slot collides and splashes and heat exchanges with the medium outside the high-flux tube, so as to improve the heat exchange efficiency.

[0039] A clamping path 12 is formed in the bracket 1. The clamping path 12 forms a closed loop, and the clamping block 2 moves along the clamping path 12, so that the clamping block 2 moves back and forth.

[0040] The clamping path 12 includes a moving section 121, a moving away section 122, a resetting section 123 and an approaching section 124 which are connected in sequence. The moving section 121 and the resetting section 123 are parallel to each other, and the moving away 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 moving away section 122, the clamping blocks 2 move away from each other to detach from the high-flux tube. When the clamping block 2 moves along the resetting section 123, the clamping block 2 moves and resets. The clamping block 2 moves along the clamping path 12, and the clamping block 2 reciprocates to complete the clamping and push the high-flux tube to move.

[0041] A block rod 24 is arranged on the clamping block 2, and a roller 25 is rotatably arranged on the block rod 24. The roller 25 rolls along the clamping path 12, so that the clamping block 2 reciprocates to clamp and push the high-flux tube to move.

[0042] Figure 3 FIG. 1 is a schematic diagram showing a top view of the clamping block of the first embodiment of the present invention. Figure 1-Figure 3 As shown, two groups of spaces 21 are formed in the clamping block 2, and pistons 22 are slidably arranged in the spaces 21. A turntable 23 is rotatably arranged on the clamping block 2, and the turntable 23 is located between adjacent spaces 21. Gears are formed on the piston 22 and the turntable 23, respectively, so that the turntable 23 engages with the piston 22. The spaces 21 are connected to the air source. The slot block 3 is arranged on the turntable 23.

[0043] The two groups of spaces 21 are respectively inlet and outlet, so that the pistons 22 in the two groups of spaces 21 move back and forth, thereby driving the turntable 23 and the slot block 3 to rotate. By controlling the amount of air inlet and outlet, the rotation angle of the slot block 3 is controlled. One group of spaces 21 inlet air, the other group of spaces 21 outlet air, the slot block 3 rotates clockwise. The other group of spaces 21 inlet air, one group of spaces 21 outlet air, the slot block 3 rotates counterclockwise.

[0044] The driving wheel set 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 arranged on the bracket 1 .

[0045] Exemplarily, there are two sets of driving wheel groups 4. The driving wheel groups 4 are respectively located on both sides of the bracket 1. Exemplarily, there are multiple sets of supporting wheels 41. The supporting wheels 41 are located below the high-flux tube, and the supporting wheels 41 are relatively staggered. The outer surface of the supporting wheel 41 is a conical surface, so that the high-flux tube is placed on the conical surface of the supporting wheel 41.

[0046] Figure 4 FIG. 1 is a schematic diagram showing the structure of the adjustment wheel according to the first embodiment of the present invention. Figure 1-Figure 4 As shown, the first power device 43 is exemplarily a motor. In the moving-out direction of the high-flux tube, a wheel rod 421 is slidably arranged around the adjusting wheel 42, and a first elastic device 422 is sleeved on the wheel rod 421. The first elastic device 422 extends to push the wheel rod 421 to move out of the adjusting wheel 42, and the wheel rod 421 is embedded in the tube groove. When the wheel rod 421 contacts the outer surface of the high-flux tube, the wheel rod 421 moves into the adjusting 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 adjusting wheel 42 to rotate, the wheel rod 421 is embedded in the tube groove, the adjusting wheel 42 drives the high-flux tube to rotate through the friction between the high-flux tube and the wheel rod 421 drives the high-flux tube to rotate by contacting and pushing the tube groove. Slipping between the adjusting wheel 42 and the high-flux tube is avoided, so that continuous processing marks cannot be formed.

[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 FIG. 1 is a schematic diagram showing the structure of the driving mechanism of the first embodiment of the present invention. Figure 1-Figure 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 barrel space 54. The step 531 is placed in the barrel space 54 and contacts the inner surface of the barrel space 54. The barrel space 54 is formed in the annular barrel 52 in the left and right directions, and the barrel spaces 54 are arranged in parallel around the annular barrel 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 the gas source, and the gas entering the cylinder space 54 pushes the step 531, so that the plate rod 53 moves 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 closer to or farther away from each other, the clamping blocks 2 move along the plate groove 511. The second elastic device 512 provides an elastic thrust, so that the clamping block 2 moves smoothly.

[0053] The high-flux tube surface processing device further includes a moving device 6. The moving device 6 includes 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 arranged on the moving plate 62.

[0054] A first clamping plate 611 is fixedly arranged on one side of the clamping ring 61, and a second clamping plate 612 is slidably arranged on the other side of the clamping ring 61. A first convex ring 613 is arranged on the first clamping plate 611, and a second convex ring 614 is arranged on the second clamping plate 612. A magnetic attraction device 615 is arranged on the first clamping plate 611, and the magnetic attraction device 615 magnetically attracts the second clamping plate 612, and the second clamping plate 612 is close to the first clamping plate 611, and the first convex ring 613 and the second convex ring 614 clamp the high-flux tube.

[0055] The diameter of the first convex ring 613 is smaller than the diameter 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 of the high-flux outer surface, so that the first convex ring 613 and the second convex ring 614 clamp the high-flux tube completely and firmly, avoiding axial or radial slippage of the high-flux tube.

[0056] The guide rail 63 is arranged in the left and right directions. A running wheel 64 and a second power device 65 are arranged below the moving plate 62. The second power device 65 drives the running wheel 64 to roll along the guide rail 63, so that the moving plate 62 moves along the guide rail 63.

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

[0058] The driving wheel set 4 drives the high-flux tube to rotate at a certain angle, so that the slot block 3 can form an inclined tube slot. Since the high-flux tube is long, when a certain position of the high-flux tube rotates, it will drive the high-flux tube to rotate as a whole. Since the high-flux tube has a heavy weight, a position far from the rotation on the high-flux tube will be twisted and deformed. At the same time, in the process of forming processing marks on the high-flux tube, the single movement distance of the high-flux tube is short, and the slot block 3 is pressed into the surface of the high-flux tube and moved out of the tube slot, it will cause the high-flux tube to shake.

[0059] The clamp ring 61 clamps both ends of the high-flux tube to prevent the high-flux tube from shaking. The moving plate 62 moves along the guide rail 63, so that the high-flux tube moves as a whole during the processing process, and the self-weight of the high-flux tube is prevented from causing resistance to the clamping block 2 pushing the high-flux tube to move. The clamp ring 61 rotates along the moving plate 62, so that the high-flux tube can rotate as a whole during the rotation process, and torsional deformation can be avoided.

[0060] Second embodiment:

[0061] A processing method for a high-flux tube surface processing device comprises the following steps:

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

[0063] According to the heat exchange conditions of the medium, the grooves on the surface of the high-flux tube can be straight grooves, spiral grooves in the same direction and angle, spiral grooves in the same direction and different angles, spiral grooves in different directions and angles alternately formed, straight grooves and spiral grooves alternately formed, etc.

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

[0065] When the grooves on the surface of the high-flux tube are spiral grooves with different angles in the same direction: when the medium flows along the outside of the high-flux tube, there are two sets of flow paths, one set of medium flows along the spiral grooves, and the other set of medium flows along the outer surface of the high-flux tube in a straight line. Depending on the structure of the heat exchanger, the flow rate of the other set of medium flowing along the outer surface of the high-flux tube changes. When the flow rate of the other set of medium is faster, the angle between the spiral groove and the edge of the high-flux tube is smaller. When the flow rate of the other set of medium is slower, the angle between the spiral groove and the edge of the high-flux tube is larger.

[0066] When the grooves on the surface of the high-flux tube are formed alternately by spiral grooves of different directions and angles: when the medium flows along the outside of the high-flux tube, there are two groups of flow paths. One group of medium flows along the spiral grooves in a clockwise spiral and a counterclockwise spiral alternately, and the other group of medium flows in a straight line along the outer surface of the high-flux tube. When one group of medium flows to the alternating position, collision and splashing occur, which causes the flow speed of one group of medium to slow down rapidly, increases the flow time of one group of medium, and improves the heat exchange efficiency of the medium. At the same time, one group of medium splashes, causing one group of medium and another group of medium to contact and mix with each other, which improves the heat exchange efficiency of the medium.

[0067] When the grooves on the surface of the high-flux tube are formed alternately of linear grooves and spiral grooves: when the medium flows along the outside of the high-flux tube, there are two sets of flow paths, one set of medium flows along the spiral grooves or flows straight along the linear grooves, and the other set of medium flows straight along the outer surface of the high-flux tube. When one set of medium flows straight along the linear grooves, the two sets of medium have the same flow rate and will not generate eddy currents. The position of the high-flux tube close to the tube sheet, sensors and other auxiliary equipment needs to be guaranteed not to be disturbed by eddy currents, so the grooves at this position are linear grooves.

[0068] The type data of the pipe groove, the distribution data of the pipe groove, the spiral angle data and the spiral direction data are sent 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 group 4 to control the start and 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 a straight pipe groove processing process and a spiral pipe groove processing process. The straight pipe groove processing process and the spiral pipe groove processing process are combined according to the data in the analysis step:
