Description

Technical Field

[0001] The invention relates to the technical field of polishing, in particular to a device for polishing the inner wall of an air cooler tube bundle. Background Art

[0002] The air cooler tube bundle is the core component of the air cooler. It is usually composed of many tubes arranged in an array, and these tubes generally have good thermal conductivity. During operation, the hot fluid flows in the tubes, and the air passes outside the tubes. The heat exchange between the air and the tube bundle is used to achieve cooling or condensation of the fluid. The air cooler tube bundle is made of various materials, the most common of which are carbon steel, stainless steel, etc., to adapt to different working environments and fluid media. Its design and construction will be adjusted according to specific application requirements and process conditions, such as the diameter, length, and arrangement of the tubes. The performance and quality of the air cooler tube bundle have a vital impact on the heat exchange efficiency and reliability of the entire air cooler; When grinding the inner wall of the air cooler tube bundle, conventional grinding tools cannot be used to grind thinner and longer tubes, so the grinding device needs to enter the inner wall of the air cooler tube bundle for grinding.

[0013] The beneficial effects of the present invention are as follows: 1. The present invention sets a rotating mechanism, and the telescopic rod drives the rotating column to contact the sandpaper and the inner wall of the air cooler tube bundle, and then the rotating block 2 is driven to rotate, so that the sandpaper and the inner wall are scratched, and then the sandpaper polishes the inner wall. The telescopic rod then slowly extends outward to perform continuous deeper polishing. After polishing for a period of time, the servo motor 3 drives the rotating column to rotate half a circle, so that the sandpaper on the other side contacts the inner wall, preventing the sandpaper from being attached to a large amount of iron filings of the air cooler tube bundle, thereby deteriorating the polishing effect. During the rotation of the sandpaper, the sandpaper will scratch the scratching knife, so that the iron filings attached to the sandpaper are scraped off.

[0014] 2. The present invention sets a cleaning brush mechanism. The rotating block 2 drives the rotating block 3 to rotate, thereby driving the cleaning brush mechanism to rotate. As the rotating block 3 rotates, the centrifugal force generated by the rotation stretches the telescopic spring 1 and moves the sliding block 1 along the sliding rod 1, and finally makes the sliding block 1 contact with the inner wall of the air cooler tube bundle. At the same time, the rotation of the sliding block 3 causes the absorbent cotton and the brush to clean the moisture and the transported material residues on the inner wall of the air cooler tube bundle to prevent the moisture and the transported material from hindering the grinding. When the sliding block 3 stops rotating, the telescopic spring 1 is reset, so that the brush contacts the scratch ring plate and the residues on the brush are removed, thereby realizing self-cleaning.

[0015] 3. The present invention sets a collection mechanism. When the rotating block 3 rotates, it will drive the support plate 2 and the spiral blades to rotate, thereby generating a wind force opposite to the moving direction of the device. The generated wind force will blow the iron filings splashed by grinding and the residues dropped by cleaning to the inner wall of the collection plate. Due to the arc design of the collection plate and the rotation of the collection plate driven by the rotating block 1, the iron filings and transported objects entering the inner wall of the collection plate will not fall from the collection plate. When the servo motor 1 stops rotating, it will make the disassembly plate at the bottom, which is convenient for the subsequent recovery and treatment of impurities. 4. The present invention provides a scratching mechanism. When the collecting plate stops rotating, due to the heavy gravity block, the inertia will cause the sliding ring and the scratching plate to continue to slide along the round rod a certain distance, thereby causing the scratching plate to scratch the inner wall of the collecting plate and scraping the iron filings and impurities attached to the collecting plate to the bottom of the collecting plate, which is convenient for subsequent recycling.

[0016] 5. The present invention sets a distance mechanism. During grinding, the moving device will drive the round rod 2 and the distance mechanism to move in parallel with the air cooler tube bundle. As the telescopic rod slowly moves outward, the distance between the magnetic block and the magnet block will become closer and closer. When the distance reaches a certain position, the attraction generated will cause the magnet block to compress the telescopic spring 2 and make the pointing plate point to a specific scale bar. When the pointing plate points to a specific scale bar, it means that the grinding is excessive, and it is necessary to stop the grinding mechanism to avoid damage to the non-rusted parts due to excessive grinding.

Example 1, using Figure 1-Figure 14 An air cooler tube bundle inner wall grinding device according to one embodiment of the present invention is described as follows.

[0033] like Figure 1-Figure 14 As shown, an air cooler tube bundle inner wall polishing device of the present invention comprises a main unit 1, a display light 2 is fixedly connected to the top of the main unit 1, a camera 3 is fixedly connected to one end of the top of the main unit 1 away from the display light 2, a moving mechanism 4 is symmetrically arranged at the bottom of the main unit 1, and a servo motor 5 is fixedly connected to the outer surface of the main unit 1; A rotating mechanism 6, which is used to grind the inner wall of the air cooler tube bundle; An auxiliary mechanism 7, the auxiliary mechanism 7 is used to detect the degree of grinding of the rotating mechanism 6; When a device for grinding the inner wall of an air cooler tube bundle is working, the device is first placed in the air cooler tube bundle that needs to be ground, and then the moving mechanism 4 drives the entire device to move in the air cooler tube bundle. At the same time, the servo motor 5 drives the rotating mechanism 6 to start working and grind the inner wall.

[0034] like Figure 4 As shown, the rotating mechanism 6 includes a rotating block 61, the outer surface of the rotating block 61 is fixedly connected to a collecting mechanism 62, the end of the rotating block 61 away from the servo motor 5 is fixedly connected to a grinding mechanism 63, and the end of the grinding mechanism 63 away from the rotating block 61 is fixedly connected to a cleaning mechanism 64; like Figure 5-Figure 7 As shown, the grinding mechanism 63 includes a rotating block 631, the outer surface of the rotating block 631 is evenly provided with a placement notch 632, the inner wall of the placement notch 632 is fixedly connected with a telescopic rod 633, the outer surface of the telescopic rod 633 is symmetrically provided with a support rod 634, the end of the support rod 634 away from the telescopic rod 633 is fixedly connected with a side plate 635, the inner wall of the side plate 635 is fixedly connected with a servo motor 636, the output end of the servo motor 636 is fixedly connected with a rotating column 637, the outer surface of the rotating column 637 is fixedly connected with a sandpaper 638, the end of the rotating column 637 away from the servo motor 636 is fixedly connected with a rotating shaft 6310, the end of the telescopic rod 633 close to the sandpaper 638 is fixedly connected with a scratching knife 639, and the outer surface of the side plate 635 is fixedly connected with a magnetic block 6311.

[0035] The servo motor 15 will drive the rotating block 1 61 to rotate. Before the rotating block 1 61 drives the rotating block 2 631 to rotate, the telescopic rod 633 will be extended outward by a certain distance. This distance is set in advance according to the diameter of the air cooler tube bundle to be polished. The telescopic rod 633 will drive the rotating column 637 and the sandpaper 638 to contact the inner wall of the air cooler tube bundle. Then, the rotating block 2 631 is driven to rotate, so that the sandpaper 638 is rubbed against the inner wall, so that the sandpaper 638 is rubbed against the inner wall. The wall is polished, and the telescopic rod 633 slowly extends outward to continue deeper polishing. After polishing for a period of time, the servo motor three 636 will drive the rotating column 637 to rotate half a circle, so that the sandpaper 638 on the other side contacts the inner wall to prevent the sandpaper 638 from being attached to a large amount of air cooler tube bundle iron filings, thereby deteriorating the polishing effect. During the rotation of the sandpaper 638, the sandpaper 638 will scratch against the scratching knife 639, so that the iron filings attached to the sandpaper 638 will be scraped off.

[0036] The outer surface of the rotating block 1 61 is fixedly connected to the output end of the servo motor 1 5 , the outer surface of the rotating block 2 631 is fixedly connected to the side of the rotating block 1 61 away from the servo motor 1 5 , and the outer surface of the rotating shaft 2 6310 is rotatably connected to the inner wall of the side plate 635 .

[0037] like Figure 8 As shown, the cleaning mechanism 64 includes a rotating block three 641, a protruding block 642 is fixedly connected to the side of the rotating block three 641 away from the rotating block one 61, a rotating shaft three 643 is evenly arranged on the outer surface of the protruding block 642, a supporting plate two 644 is fixedly connected to the outer surface of the rotating shaft three 643, a spiral fan blade 645 is fixedly connected to the end of the supporting plate two 644 away from the rotating shaft three 643, a placement notch two 646 is evenly arranged on the outer surface of the rotating block three 641, and a cleaning mechanism 647 is fixedly connected to the inner wall of the placement notch two 646.

[0038] The second rotating block 631 drives the third rotating block 641 to rotate, thereby driving the cleaning mechanism 647 to rotate.

[0039] like Fig. 9 As shown, the cleaning mechanism 647 includes a sliding rod 6471, on which a telescopic spring 6472 is sleeved, one end of the telescopic spring 6472 is fixedly connected to the inner wall of the placement notch, the other end of the telescopic spring 6472 is fixedly connected to a sliding block 6473, the outer surface of the sliding block 6473 is slidably connected to the inner wall of the sliding block 6473, one end of the sliding block 6473 away from the telescopic spring 6472 is fixedly connected to absorbent cotton 6475, the outer surface of the sliding block 6473 is evenly provided with brushes 6474, and the inner wall of the placement notch 632 is fixedly connected to a scratch ring plate 6476.

[0040] As the rotating block three 641 rotates, the centrifugal force generated by the rotation stretches the telescopic spring one 6472 and moves the sliding block one 6473 along the sliding rod one 6471, and finally makes the sliding block one 6473 contact the inner wall of the air cooler tube bundle. At the same time, the rotation of the sliding block three will make the absorbent cotton 6475 and the brush 6474 clean the moisture and transported material residues on the inner wall of the air cooler tube bundle to prevent the moisture and the transported material from hindering the grinding. When the sliding block three stops rotating, the telescopic spring one 6472 is reset, so that the brush 6474 contacts the scratch ring plate 6476, and the residue on the brush 6474 is removed, thereby realizing self-cleaning.

[0041] The outer surface of the rotating block three 641 is fixedly connected to the end of the sliding block two away from the sliding block one 6473, and one end of the sliding rod one 6471 is fixedly connected to the inner wall of the placement notch one 632.

[0042] The specific workflow is as follows: During operation, since the device moves along the air cooler tube bundle, before grinding the inner wall, the rotating block three 641 will be driven to rotate, and the centrifugal force generated by the rotation stretches the telescopic spring one 6472 and makes the sliding block one 6473 move along the sliding rod one 6471, and finally makes the sliding block one 6473 contact the inner wall of the air cooler tube bundle. At the same time, the rotation of the sliding block three will make the absorbent cotton 6475 and the brush 6474 clean the moisture and transported material residues on the inner wall of the air cooler tube bundle, and the servo motor one 5 will drive the rotating block one 61 to rotate, and the rotating block one 61 drives the rotating block two 631 to rotate.

The telescopic rod 633 will drive the rotating column 637 and the sandpaper 638 to contact the inner wall of the air cooler tube bundle, and then the rotating block 2 631 will be driven to rotate, thereby causing the sandpaper 638 to scratch the inner wall. The telescopic rod 633 will then slowly extend and retract outward, thereby continuing to polish deeper. After polishing for a period of time, the servo motor three 636 will drive the rotating column 637 to rotate half a circle, so that the sandpaper 638 on the other side contacts the inner wall to prevent the polishing effect from deteriorating.

[0043] Embodiment 2, use Figure 1-Figure 14 An air cooler tube bundle inner wall grinding device according to one embodiment of the present invention is described as follows.

[0044] like Figure 1-Figure 14 As shown, an air cooler tube bundle inner wall grinding device of the present invention is based on the first embodiment, as shown in Figure 10-11 As shown, the collecting mechanism 62 includes a collecting plate 621, the inner wall of the collecting plate 621 is fixedly connected to the outer surface of the rotating block 61, a disassembly plate 622 is connected to the collecting plate 621 by threaded screws, and a scratching mechanism 623 is fixedly connected to the inner wall of the collecting plate 621.

[0045] When the rotating block three 641 rotates, it will drive the support plate two 644 and the spiral fan blades 645 to rotate, thereby generating a wind force opposite to the moving direction of the device. The generated wind force will blow the iron filings splashed by grinding and the residues dropped from cleaning to the inner wall of the collecting plate 621. Due to the arc design of the collecting plate 621 and the rotation of the collecting plate 621 driven by the rotating block one 61, the iron filings and transported objects entering the inner wall of the collecting plate 621 will not fall from the collecting plate 621.

[0046] like Fig.12As shown, the scratch mechanism 623 includes a support rod three 6231, which is evenly arranged on the inner wall of the collecting plate 621, the outer surface of the support rod three 6231 is fixedly connected with a round rod one 6232, the outer surface of the round rod one 6232 is slidably connected with a sliding ring 6233, the outer surface of the sliding ring 6233 is fixedly connected with a scratch plate 6234, the outer surface of the scratch plate 6234 is fixedly connected with a gravity block 6235, and the side of the scratch plate 6234 away from the gravity block 6235 is slidably connected to the inner wall of the collecting plate 621.

[0047] When the servo motor 5 stops rotating, the disassembly plate 622 will be at the bottom, which is convenient for the subsequent recovery of impurities. When the collecting plate 621 stops rotating, due to the heavy gravity block 6235, the inertia will cause the sliding ring 6233 and the scratch plate 6234 to continue to slide along the round rod 6232 for a distance, thereby causing the scratch plate 6234 to scratch the inner wall of the collecting plate 621 and scrape the iron filings and impurities attached to the collecting plate 621 to the bottom of the collecting plate 621.

[0048] like Figure 3 As shown, the moving mechanism 4 includes a support rod 41, both ends of the support rod 41 are fixedly connected to the bottom of the main machine 1, the outer surface of the support rod 41 is slidably connected to a sliding plate 42, one end of the sliding plate 42 away from the support rod 41 is rotatably connected to a rotating shaft 43, the outer surface of the rotating shaft 43 is fixedly connected to a support plate 45, one end of the rotating shaft 43 is fixedly connected to a rotating handle 44, the outer surface of the support plate 45 is fixedly connected to a servo motor 46, the output end of the servo motor 46 is fixedly connected to a roller 47, and the outer surface of the roller 47 is slidably connected to a track 48.

[0049] The position of the sliding plate 42 can be adjusted to control the height of the moving mechanism 4 inside the air cooler tube bundle, so that the rotating mechanism 6 is in a circular position of the air cooler tube bundle to facilitate subsequent grinding. After that, the servo motor 46 will rotate the roller 47, thereby driving the crawler 48 to move, thereby moving the entire device.

[0050] like Fig.13 As shown, the auxiliary mechanism 7 includes a round rod 71, the inner wall of which is evenly provided with cylinders 73, the outer surface of the cylinder 73 is fixedly connected to a support rod 74, the end of the support rod 74 away from the cylinder 73 is fixedly connected to a moving device 75, and the outer surface of the round rod 71 is fixedly connected to a distance mechanism 72.

[0051] During the grinding process, the moving device 75 drives the second round rod 71 and the distance mechanism 72 to move in parallel with the rotating mechanism 6 of the air cooler tube bundle.

[0052] like Fig.14As shown, the distance mechanism 72 includes a circular plate 721, the inner wall of the circular plate 721 is fixedly connected to the outer surface of the round rod 71, the circular plate 721 is evenly provided with scale bars 722, the outer surface of the circular plate 721 is evenly provided with measuring notches 727, the inner wall of the measuring notch 727 is fixedly connected to a sliding rod 723, the sliding rod 723 is sleeved with a telescopic spring 724, one end of the telescopic spring 724 is fixedly connected to the inner wall of the measuring notch 727, the other end of the telescopic spring 724 is fixedly connected to a magnet block 725, the inner wall of the magnet block 725 is slidably connected to the outer surface of the sliding rod 723, and the outer surface of the magnet block 725 is fixedly connected to a pointing plate 726.

[0053] As the telescopic rod 633 moves slowly outward, the distance between the magnetic block 6311 and the magnet block 725 will become closer and closer. When the distance reaches a certain position, the attraction generated will cause the magnet block 725 to compress the telescopic spring 2 724 and make the pointing plate 726 point to the specific scale bar 722. When the pointing plate 726 points to the specific scale bar 722, it means that the grinding is excessive, and it is necessary to stop the grinding mechanism 63 to avoid excessive grinding causing damage to the non-rusted parts.

[0054] The specific workflow is as follows: During operation, the position of the sliding plate 42 can be adjusted to control the height of the moving mechanism 4 inside the air cooler tube bundle, so that the rotating mechanism 6 is in a circular position of the air cooler tube bundle, which is convenient for subsequent grinding. Then, the servo motor 46 will rotate the roller 47, thereby driving the crawler 48 to move, so that the entire device moves. While the grinding mechanism 63 is working, the rotation of the rotating block 3 641 will drive the support plate 2 644 and the spiral fan blade 645 to rotate, thereby generating a wind force opposite to the moving direction of the device. The generated wind force will blow the iron filings splashed by grinding and the residues cleaned up to the inner wall of the collecting plate 621. When the servo motor 5 stops rotating, the disassembly plate 622 will be at the bottom, which is convenient for the subsequent recovery of impurities. When the collecting plate 621 stops rotating, due to the heavy weight block 6235, the inertia will cause the sliding ring 6233 and the scratch plate 6234 to continue to move. Continue to slide one end distance along the round rod 1 6232, so that the scratch plate 6234 and the inner wall of the collecting plate 621 are scratched and the iron filings and impurities attached to the collecting plate 621 are scraped to the bottom of the collecting plate 621, which is convenient for subsequent collection and processing. While grinding, the moving device 75 will drive the round rod 2 71 and the distance mechanism 72 to move in parallel with the rotating mechanism 6 of the air cooler tube bundle. As the telescopic rod 633 slowly moves outward, the distance between the magnetic block 6311 and the magnet block 725 will also be driven closer and closer. When the distance reaches a certain position, the attraction generated will cause the magnet block 725 to compress the telescopic spring 2 724 and make the pointing plate 726 point to a specific scale bar 722. When the pointing plate 726 points to a specific scale bar 722, it means that the grinding is excessive, and it is necessary to stop the work of the grinding mechanism 63 to avoid excessive grinding causing damage to the non-rusted parts.
