Description

Technical Field

[0001] The invention relates to the technical field of glass-lined reactor processing, in particular to a pin-turning and hole-pulling device for a glass-lined reactor cylinder. Background Art

[0002] Glass-lined reactors are made of a composite material made by lining the inner surface of a steel container with high-silicon dioxide glass. After high-temperature sintering, the glass-lined reactor is firmly bonded to the metal surface. During the processing of the glass-lined reactor, the two main sections need to be welded together through welding. After welding, a large amount of welding slag will be generated along the weld and adhere to the weld. Therefore, a turning and boring device is required to clean and pull the welding slag in the weld.

[0003] During the use of the existing turning and hole-pulling devices for glass-lined reactors on the market, some welds are usually opened with U-shaped grooves for welding before welding. Therefore, the welding slag in the weld after welding also adheres to the weld in a U-shaped cross-section. Simply turning and grinding the weld surface with a turning device is not enough to clean the welding slag in the U-shaped weld. The residual welding slag can easily obscure the weld, affecting the quality inspectors' judgment on whether there is a cold weld in the weld, and thus affecting the quality inspection results.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. In the present invention, the main body of the glass-lined reactor is driven to rotate. The rotation of the main body of the glass-lined reactor causes the end of the turning tool to slide in the weld seam. Since the end of the turning tool is inserted into the welding slag in the weld seam, the sliding allows the turning tool to push the welding slag out of the weld seam. When the turning tool moves along the weld seam, it slides in the weld seam in a wavy curved trajectory. The wavy sliding trajectory further scrapes off the welding slag in the weld seam, so that the welding slag in the weld seam is cleaned more evenly.

[0021] 2. In the present invention, as the vacuum pump tilts, the second blocks on both sides are pushed closer to each other, and the second blocks approach each other with the arc scrapers. The two arc scrapers approaching each other will scrape and gather the welding slag adhered near the outer opening of the weld, so that it is more gathered in the circumferential weld.

[0022] 3. In the present invention, the transmission motor is started in reverse, causing the second guide rod to slide into the second annular groove along the arc groove. The second guide rod rotates with a turning tool and an air pump. The air pump rotates along the rotation of the first ball, causing the air pump to tilt toward the side close to the air pump head, causing the output end of the air pump head to contact the weld. At this time, as the inner gear ring rotates, the air pump head can be made to follow a wave path in the opposite direction of the weld to extract the slag remaining in the weld that was scraped off by the air pump head, thereby completing further cleaning of the weld.

[0042] The outer wall of the fixing frame 40 is fixedly connected to a guide rod 47 , and the outer wall of the guide rod 47 is slidably connected to two arc scrapers 49 . The outer walls of the two arc scrapers 49 are both fixedly connected to a third spring 48 , and the third spring 48 is fixedly connected to the outer wall of the fixing frame 40 .

[0045] A transmission motor 2 is fixedly installed on the outer wall of the turning and hole pulling workbench main body 1, and the output end of the transmission motor 2 is fixedly connected to the first horizontal axis 3. One end of the first horizontal axis 3 is rotatably connected to the outer wall of the turning and hole pulling workbench main body 1, and the inner wall of the turning and hole pulling workbench main body 1 is rotatably connected to the second horizontal axis 4. The outer wall of the first horizontal axis 3 is fixedly connected to a gear 21, and the gear 21 is meshed with the inner gear ring 22.

[0046] First cylinders 5 are fixedly installed on both sides of the turning and boring workbench main body 1 , and a push block 6 is fixedly connected to the output end of the first cylinder 5 .

[0047] A first sliding groove 7 is formed on the outer wall of the turning and hole-drawing workbench body 1 , and the push block 6 is slidably connected in the first sliding groove 7 .

[0048] In this embodiment, when using the glass-lined reactor turning and punching device, the glass-lined reactor body 9 to be turned is first placed on the surfaces of the first transverse axis 3 and the second transverse axis 4 by a crane. Then, the first cylinders 5 on both sides are activated to push and move the glass-lined reactor body 9 along the surfaces of the first transverse axis 3 and the second transverse axis 4 until the part of the glass-lined reactor body 9 to be cut is below the exhaust head 15, completing the preparation work.

[0049] Then start the transmission motor 2. After the transmission motor 2 is started, the gear 21 at the output end rotates. The gear 21 rotates and drives the inner gear ring 22 to rotate through the meshing relationship. When the inner gear ring 22 rotates, the second annular groove 26 and the first annular groove 25 on the outer wall of the inner gear ring 22 rotate synchronously. At this time, the second guide rod 37 in the second annular groove 26 will rotate with the second annular groove 26 and eventually enter the arc groove 27. Due to the path of the arc groove 27, the second guide rod 37 will be subjected to force at this time. The turning tool 16 with one end of the force belt is forced downward. At this time, the turning tool 16 brings the side of the vacuum pump 13 downward. The end of the turning tool 16 is pressed and inserted into the weld, penetrating the welding slag generated by the welding. Due to the rotation of the first horizontal axis 3 and the second horizontal axis 4, the glass-lined reactor body 9 is driven to rotate. The rotation of the glass-lined reactor body 9 causes the end of the turning tool 16 to slide in the weld. Since the end of the turning tool 16 is inserted into the welding slag in the weld, the sliding of the turning tool 16 causes the welding slag to be pushed out of the weld.

[0050] As the inner gear ring 22 continues to rotate, the first protrusions 23 and the hemispherical grooves 24 evenly distributed on the outer wall of the inner gear ring 22 also rotate synchronously. It should be noted that in the initial state, the air pump 13 is in a state where the first guide rod 36 with the end enters the hemispherical groove 24 due to the action of the first springs 14 on both sides. As the inner gear ring 22 rotates, the first guide rod 36 will slide along the hemispherical groove 24 to the surface of the inner gear ring 22. At this time, the end of the first guide rod 36 protrudes outside the hemispherical groove 24. Therefore, at this time, the first guide rod 36 will carry one side of the air pump 13 to rotate in the horizontal direction away from the inner gear ring 22. As the first guide rod 36 slides along the surface of the inner gear ring 22 and hits the first protrusion 23, the friction causes the first guide rod 36 to carry one side of the air pump 13 along the first rolling The ball 12 continues to rotate horizontally in the direction away from the inner gear ring 22. When the inner gear ring 22 continues to rotate, prompting the first guide rod 36 to slide into the hemispherical groove 24, the two first springs 14 bent due to the above rotation are reset, prompting the vacuum pump 13 to move with the first guide rod 36, prompting the first guide rod 36 to enter the hemispherical groove 24. At this time, the vacuum pump 13 rotates horizontally along the first rolling ball 12 to the initial position. Since the first protrusion 23 and the hemispherical groove 24 are evenly distributed, the vacuum pump 13 rotates back and forth horizontally clockwise and counterclockwise along the rotation point of the first rolling ball 12. At this time, the turning tool 16 slides in the weld seam with a wave-bent trajectory. The wave sliding trajectory further scrapes off the welding slag in the weld seam, so that the welding slag in the weld seam is cleaned more evenly.

[0051] The tilt of the vacuum pump 13 causes the two curved scrapers 49 at the lower end of the vacuum pump 13 to be pressed against the glass-lined reactor body 9, and the two curved scrapers 49 are symmetrically positioned along the weld. When the vacuum pump 13 rotates horizontally back and forth clockwise and counterclockwise, the third guide rod 44 on the outer wall of the vacuum pump 13 rotates accordingly. At this time, the curved scraper 49 is pressed against the outer wall of the glass-lined reactor body 9 and cannot rotate due to contour problems. Therefore, the vacuum pump 13 rotates along the rotating connection of the second ball 38, and moves with the third guide rod 44 during the rotation process, and the movement trajectory of the third guide rod 44 will be The third inclined surface 53 contacts the outer wall of the third stop 52, forcing the third stop 52 to be forced downward. The third stop 52 is forced downward to press the first stop 45 downward. The first stop 45 moves downward, and the first stop 45 compresses the return spring 43 with the lifting frame 42 to cause displacement. The lifting frame 42 enters the groove 41. At this time, the first inclined surface 46 contacts the second inclined surface 51, forcing the second stops 50 on both sides to approach each other. The second stops 50 approach each other and the arc scraper 49 approaches each other. The two second stops 50 approaching each other will scrape and gather the welding slag adhered near the outer opening of the weld, so that it is more gathered in the girth weld.

[0052] When the second guide rod 37 slides along the first annular groove 25 for one circle, it will finally hit the first stopper 29, causing the first stopper 29 to rotate along the third transverse axis 28 and twist the first torsion spring 30 to facilitate reset, so that the second guide rod 37 passes the obstruction of the first stopper 29, and then the transmission motor 2 is started in the reverse direction, causing the second guide rod 37 to slide along the arc groove 27 into the second annular groove 26, and the second guide rod 37 rises during the sliding process, and the second guide rod 37 carries a turning tool 16 with it. As the vacuum pump 13 rotates, the vacuum pump 13 rotates along the rotation point of the first ball 12, causing the vacuum pump 13 to tilt toward the side close to the vacuum head 15, causing the output end of the vacuum head 15 to contact the weld. At this time, as the inner gear ring 22 rotates, the vacuum head 15 can be made to follow a wave path along the weld to extract the debris scraped off by the vacuum head 15 and remaining in the weld. The movement path of the above-mentioned vacuum head 15 during wave swinging matches the groove profile in the weld of the glass-lined reactor body 9.
