[0002] Seamless steel pipes are steel pipes made from a single piece of metal without any seams on their surface. According to the production method, seamless pipes are divided into hot-rolled pipes, cold-rolled pipes, cold-drawn pipes, extruded pipes, and top-rolled pipes. According to the cross-sectional shape, seamless steel pipes are divided into round and irregular shapes. Irregularly shaped pipes include square, oval, triangular, hexagonal, seed-shaped, star-shaped, and finned pipes, among other complex shapes.
[0003] When seamless steel pipes are left to stand for a long time, their surface will rust, requiring rust removal. This necessitates the use of a seamless steel pipe rust removal machine.

[0016] Compared with the prior art, the beneficial effects of the present invention are:
[0017] This seamless steel pipe rust removal machine with a drying mechanism uses four external grinding brushes to grind the exterior of the seamless steel pipe and an internal grinding brush to grind and remove rust from the inner wall of the seamless steel pipe. This allows for simultaneous grinding of the inner and outer walls of the seamless steel pipe, thereby improving the convenience of grinding the seamless steel pipe and increasing the speed of rust removal.
[0018] This seamless steel pipe rust removal machine with a drying mechanism allows residue to enter the interior of the suction baffle, suction connecting pipe, and connecting box, then the suction hose, and finally the residue treatment box. This facilitates the collection and treatment of residue inside the seamless steel pipe, preventing impurities from accumulating inside and minimizing residue buildup. This reduces the difficulty of subsequent cleaning and improves the convenience of cleaning the seamless steel pipe. Furthermore, the suction disc and suction port rotate with the rotating grinding rod, allowing for multi-angle treatment of residue and maximizing the effectiveness of residue removal.
[0019] This seamless steel pipe rust removal machine with a drying mechanism draws air into the residue treatment box through the suction box and connecting pipe, thus facilitating the treatment of residue inside the rust removal box and minimizing the accumulation of impurities inside, thereby improving the cleaning effect of the rust removal box.
[0020] This seamless steel pipe rust removal machine with a drying mechanism filters the residue sucked into the residue treatment box through a filter screen, allowing the filtered air to enter the suction pipe. This facilitates the treatment of the air drawn into the negative pressure fan, minimizing the entry of impurities into the fan and reducing the accumulation of dust and impurities, thus improving the cleanliness of the fan. It also facilitates the collection and treatment of residue, which can be easily disposed of in a collection box for centralized processing.
[0021] The seamless steel pipe rust removal machine with a drying mechanism discharges through the exhaust port. Since the exhaust port rotates with the rotating grinding rod, it is convenient to dry the inside of the seamless steel pipe from multiple angles, thereby improving the convenience of drying the inside of the seamless steel pipe, reducing the difficulty of drying the seamless steel pipe, reducing the moisture inside the seamless steel pipe, and preventing secondary rusting. At the same time, it is convenient to dry during grinding, which improves the efficiency of processing seamless steel pipes.
[0022] The seamless steel pipe rust removal machine with a drying mechanism discharges through the exhaust port. Since the exhaust port rotates with the rotating grinding rod, it is convenient to dry the inside of the seamless steel pipe from multiple angles, thereby improving the convenience of drying the inside of the seamless steel pipe, reducing the difficulty of drying the seamless steel pipe, reducing the moisture inside the seamless steel pipe, and preventing secondary rusting. At the same time, it is convenient to dry during grinding, which improves the efficiency of processing seamless steel pipes.
[0023] This seamless steel pipe rust removal machine with a drying mechanism uses eight drive wheels to clamp the seamless steel pipe through the elastic force of four compression springs. At the same time, one end of the inner grinding brush enters the interior of the seamless steel pipe to grind the inside of the seamless steel pipe. This makes it easier to fix the seamless steel pipe inside the rotating ring, thereby facilitating the processing of the seamless steel pipe, improving the convenience of processing the seamless steel pipe, and preventing the seamless steel pipe from moving automatically.
[0024] This seamless steel pipe rust removal machine with a drying mechanism rotates eight drive wheels in the same way, thereby moving the seamless steel pipe between the eight drive wheels. At the same time, the seamless steel pipe rotates along with the rotating ring, which facilitates the movement and rotation of the seamless steel pipe, thereby facilitating the processing of the seamless steel pipe and enabling all-round grinding of different positions inside and on the surface of the seamless steel pipe, thus improving the convenience of rust removal.
[0025] This seamless steel pipe rust removal machine with a drying mechanism allows the moving block to return to its original position via the spring force of a return spring. This facilitates the retraction of the second exhaust hose, improving its neatness within the rust removal box and preventing it from falling between the multiple external grinding brushes and becoming entangled. This ensures stable operation of the device and prevents the second exhaust hose from becoming tangled, thus avoiding interference with the equipment.
[0026] This seamless steel pipe rust removal machine with a drying mechanism uses a single motor to drive multiple mechanisms, thereby reducing equipment costs, lowering energy consumption, and enhancing the product's highlights and advantages. Attached Figure Description

[0048] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0049] To further understand the content of this invention, a detailed description of the invention will be provided in conjunction with the accompanying drawings.
[0050] Please see Figure 1-13 The present invention provides a technical solution: a seamless steel pipe rust removal machine with a drying mechanism, comprising a rust removal box 1, a drying mechanism 3 for drying the seamless steel pipe is provided on the top of the rust removal box 1, a residue collection mechanism 2 for collecting residue from the seamless steel pipe is provided on the drying mechanism 3, a driving internal rust removal mechanism 4 for driving is provided on one side of the rust removal box 1, a rotating moving mechanism 5 for fixing and driving the seamless steel pipe is provided inside the rust removal box 1, an external grinding mechanism 6 for grinding the outside of the seamless steel pipe is provided on one side of the rotating moving mechanism 5, the driving internal rust removal mechanism 4 is used to drive the drying mechanism 3, the rotating moving mechanism 5, and the external grinding mechanism 6, and a pipe receiving device is provided inside the rust removal box 1.
[0051] The internal rust removal mechanism 4 includes a motor 407, which is fixedly installed on one side of the rust removal box 1. A threaded rod 403 is fixedly installed at the output end of the motor 407. The threaded rod 403 is rotatably connected inside the rust removal box 1. One end of the threaded rod 403 rotatably passes through the rust removal box 1 and extends to the other side of the rust removal box 1. A sliding inner ring 404 is slidably connected inside the threaded rod 403. A spring spring 409 is movably sleeved on one end of the sliding inner ring 404 inside the threaded rod 403. The two ends of the spring spring 409 are respectively connected to the threaded rod 403. The grinding rod 403 and the sliding inner ring 404 are fixedly connected. A movable frame 401 is rotatably sleeved on one end of the sliding inner ring 404. A rotating grinding rod 402 is rotatably connected inside the movable frame 401. A pulley 410 is fixedly sleeved on one end of the rotating grinding rod 402 inside the movable frame 401. A pulley 410 is also fixedly sleeved on one end of the sliding inner ring 404 extending into the movable frame 401. A belt 411 is connected to the two pulleys 410 for transmission. An inner grinding brush 412 is fixedly sleeved on the rotating grinding rod 402.
[0052] When grinding the inner wall of a seamless steel pipe, the inner grinding brush 412 is inserted into the pipe. The motor 407 is then started, causing the threaded rod 403 to rotate, which in turn rotates the sliding inner ring 404. This, in turn, drives the grinding rod 402 to rotate via the two sliding inner rings 404 and the belt 411. The rotation of the grinding rod 402 then drives the inner grinding brush 412 to rotate, thus grinding and removing rust from the inner wall of the seamless steel pipe. This reduces rust spots inside the pipe and improves the ease of grinding.
[0053] Four protrusions 405 are fixedly installed on the surface of the sliding inner ring 404. The four protrusions 405 are slidably connected inside the threaded rod 403. Two limiting rods 406 are slidably connected inside the rust removal box 1. Both limiting rods 406 slide through the rust removal box 1 and extend to the outside of the rust removal box 1. Both limiting rods 406 are fixedly connected to the movable frame 401.
[0054] The four protrusions 405 facilitate the sliding inner ring 404 to slide inside the threaded rod 403. At the same time, when the threaded rod 403 rotates, it drives the sliding inner ring 404 to rotate, thereby preventing the sliding inner ring 404 from not rotating when the threaded rod 403 rotates.
[0055] The two limiting rods 406 facilitate the restriction of the movable frame 401, thereby enabling the movable frame 401 to move horizontally.
[0056] The residue collection mechanism 2 includes a negative pressure fan 201, which is fixedly installed on the top of the rust removal box 1. A suction pipe 202 is fixedly installed at the suction end of the negative pressure fan 201. A residue treatment box 204 is fixedly installed at the end of the suction pipe 202 away from the negative pressure fan 201, and the suction pipe 202 and the residue treatment box 204 are interconnected. A suction hose 206 is fixedly installed on one side of the residue treatment box 204, and the suction hose 206 is connected to the interior of the residue treatment box 204. A connecting box 207 is fixedly installed at the end of the suction hose 206 away from the residue treatment box 204. A rotating grinding rod 402 is rotatably connected to one side of the connecting box 207. The connecting box 207 is fixedly connected to the surface of the movable frame 401. The suction hose 206 is connected to the interior of the connecting box 207, which is divided into two cavities. The suction hose 206 is connected to one of the cavities in the connecting box 207. A suction connection pipe 210 is fixedly connected to one side of the connecting housing 207. The suction connection pipe 210 passes through the interior of the rotating grinding rod 402 but does not contact the interior of the rotating grinding rod 402. The suction connection pipe 210 and the connecting housing 207 are interconnected. The connecting housing 207 and the suction hose 206 are connected to the same cavity. A suction baffle 208 is fixedly installed at one end of the suction connection pipe 210. The suction baffle 208 is rotatably connected to the interior of the rotating grinding rod 402. The interior of the suction baffle 208 is flared. A suction disc 209 is fixedly fitted on the surface of the rotating grinding rod 402. A suction port 211 is opened on the suction disc 209. The other end of the suction port 211 passes through the suction disc 209 and the rotating grinding rod 402 and extends into the interior of the rotating grinding rod 402. The suction port 211 is connected to a cavity formed by the suction baffle 208 and the rotating grinding rod 402.
[0057] The negative pressure fan 201 is activated, drawing air from the suction pipe 202. This draws the gas inside the residue handling box 204 into the negative pressure fan 201, creating a strong negative pressure inside the residue handling box 204. This negative pressure then draws air from the suction hose 206, and further from the connecting box 207. The suction connecting pipe 210 and the suction baffle 208 are also subjected to negative pressure, causing the gas inside the seamless steel pipe to enter the rotating grinding rod 402 through the suction port 211 on the suction disc 209. This causes the suction baffle 208 to draw air in, and the powerful suction draws the ground residue through the suction port 211 into the rotating grinding rod 402. Inside the 02, the residue enters the suction baffle 208, the suction connecting pipe 210, and the connecting box 207, then the suction hose 206, and finally the residue treatment box 204. This facilitates the collection and treatment of residue inside the seamless steel pipe, preventing impurities from accumulating inside the seamless steel pipe and minimizing residue buildup. This reduces the difficulty of later cleaning and improves the convenience of cleaning the seamless steel pipe. At the same time, since the suction disc 209 and the suction port 211 rotate with the rotating grinding rod 402, the suction port 211 can rotate, facilitating multi-angle treatment of residue and maximizing the effect of residue treatment.
[0058] Because the suction baffle 208 is flared, it is easier for impurities to enter the interior of the suction baffle 208, thus facilitating the processing of the impurities.
[0059] The rust removal box 1 is fixedly installed with an air suction box 212. The air suction box 212 is connected to the interior of the rust removal box 1, passes through the rust removal box 1 and extends to the outside of the rust removal box 1. A connecting pipe 203 is connected between the residue treatment box 204 and the air suction box 212. The two ends of the connecting pipe 203 are respectively connected to the residue treatment box 204 and the air suction box 212.
[0060] When air is drawn into the residue treatment box 204, impurities inside the rust removal box 1 are drawn into the residue treatment box 204 through the suction box 212 and the connecting pipe 203, which facilitates the treatment of residues inside the rust removal box 1 and minimizes the accumulation of impurities inside the rust removal box 1, thereby improving the cleaning effect inside the rust removal box 1.
[0061] A collection box 205 is slidably connected inside the residue treatment box 204. A filter screen 213 is fixedly installed on the top of the collection box 205. The filter screen 213 is located at the connection between the residue treatment box 204 and the suction pipe 202.
[0062] The residue sucked into the residue treatment box 204 is filtered through the filter screen 213, which then allows the filtered air to enter the air intake pipe 202. This facilitates the treatment of the air drawn into the negative pressure fan 201, thereby minimizing the entry of impurities into the negative pressure fan 201, reducing the accumulation of dust and impurities inside the negative pressure fan 201, improving the cleanliness of the negative pressure fan 201, and facilitating the collection and treatment of the residue. The residue can then be poured out through the collection box 205 for centralized treatment.
[0063] The drying mechanism 3 includes a heating connection box 306, which is fixedly connected to the air outlet of the negative pressure fan 201. A heating component for heating air is fixedly installed inside the heating connection box 306. A first exhaust hose 301 is fixedly connected to one side of the heating connection box 306, communicating with the interior of the heating connection box 306. An exhaust connection pipe 302 is fixedly installed on one side of the connecting box 207, communicating with the interior of the connecting box 207. The exhaust connection pipe 302 and the first exhaust hose 301 communicate with another cavity inside the connecting box 207. The end of the exhaust connection pipe 302 furthest from the connecting box 207 is fixedly installed with… There is a partition 305, which is rotatably connected to the interior of the rotating grinding rod 402. The suction connection pipe 210 passes through the partition 305 and extends to one side of the partition 305. The exhaust connection pipe 302 extends into the interior of the rotating grinding rod 402. A chamber is formed between the partition 305 and the suction baffle 208. Sealing gaskets are provided between the suction baffle 208, the partition 305, and the rotating grinding rod 402. An exhaust disc 303 is fixedly sleeved on the surface of the rotating grinding rod 402. An exhaust port 304 is opened on one side of the exhaust disc 303. The other end of the exhaust port 304 passes through the interior of the rotating grinding rod 402 and communicates with the chamber formed by the partition 305 and the suction baffle 208.
[0064] Both the intake disc 209 and the exhaust disc 303 are fitted to the inner wall of the seamless steel pipe, thereby preventing impurities from being blown out of the interior of the seamless steel pipe when the exhaust port 304 is drying.
[0065] When drying the inside of the seamless steel pipe, the negative pressure fan 201 draws in gas and delivers it into the heating connection box 306. The heating wire inside the heating connection box 306 heats the gas, which is then delivered into the first exhaust hose 301. The first exhaust hose 301 delivers the gas into the cavity inside the connection box 207, and then through the exhaust connection pipe 302 into a chamber formed by the partition 305 and the suction baffle 208. Finally, the gas is discharged through the exhaust port 304. Since the exhaust port 304 rotates with the rotating grinding rod 402, it is convenient to dry the inside of the seamless steel pipe from multiple angles, thereby improving the convenience of drying the inside of the seamless steel pipe, reducing the difficulty of drying the seamless steel pipe, reducing the moisture inside the seamless steel pipe, and preventing secondary rusting. At the same time, it is convenient to dry during grinding, which improves the efficiency of processing the seamless steel pipe.
[0066] A movable air outlet hollow ring 307 is threadedly connected to the threaded rod 403. An air outlet hole 308 is opened inside the movable air outlet hollow ring 307. A limiting slide rod 408 is fixedly installed inside the rust removal box 1. The surface of the limiting slide rod 408 is slidably connected to the inside of the movable air outlet hollow ring 307. A second exhaust hose 309 is fixedly connected to the bottom of the heating connection box 306. The second exhaust hose 309 communicates with the inside of the heating connection box 306. The end of the second exhaust hose 309 away from the heating connection box 306 passes through the inside of the rust removal box 1 and communicates with the inside of the movable air outlet hollow ring 307.
[0067] When the threaded rod 403 rotates, the movable air outlet hollow ring 307 is restricted by the limiting slide rod 408, causing the movable air outlet hollow ring 307 to move. This movement of the air outlet 308 and the movable air outlet hollow ring 307 allows the heated air inside the heating connection box 306 to enter the second exhaust hose 309 and then the movable air outlet hollow ring 307, before being discharged through the air outlet 308. Simultaneously, the movement of the movable air outlet hollow ring 307 dries the outer wall of the seamless steel pipe, facilitating simultaneous drying of both the inner and outer walls of the seamless steel pipe. This improves the convenience of drying the seamless steel pipe, minimizes the difficulty of drying, and increases the drying speed.
[0068] The rotary moving mechanism 5 includes two rotating rings 501, which are rotatably connected to the inner wall of the rust removal box 1. The two rotating rings 501 have identical structures. Four sliding brackets 506 are slidably connected inside each rotating ring 501. Four compression springs 509 are fixedly installed inside each rotating ring 501, and are respectively fixedly connected to the four sliding brackets 506. Each of the four sliding brackets 506 has a connecting output shaft 512 rotatably connected inside. Each of the four connecting output shafts 512 movably passes through the rotating ring 501 and extends to the outside of the rotating ring 501. A small gear 504 is fixedly installed at one end of each of the four connecting output shafts 512. A fixed gear ring 503 is fixedly installed on the inner wall of the rust removal box 1. The four small gears... All gears 504 are meshed with fixed gear rings 503. The thickness of pinion 504 is greater than the length of the teeth of fixed gear ring 503. Drive shafts 508 are rotatably connected inside the four sliding frames 506. Worm gears 510 are fixedly sleeved on the four drive shafts 508. Worms 511 are fixedly sleeved on one end of the four connecting output shafts 512 that extend into the interior of the sliding frame 506. The four worm gears 511 mesh with the four worm gears 510 respectively. Drive wheels 507 are fixedly installed on both ends of the four drive shafts 508. Rubber pads are fixedly sleeved on the eight drive wheels 507. Transmission gear rings 505 are fixedly sleeved on the surface of rotating ring 501. Drive gears 502 are fixedly sleeved on threaded rod 403. Drive gears 502 mesh with transmission gear rings 505.
[0069] The seamless steel pipe moves between the eight drive wheels 507, causing the four drive wheels 507 to press against each other. This causes the four sliding frames 506 to slide inward into the rotating ring 501, pressing against the four compression springs 509. Consequently, the four connecting output shafts 512 slide outward, causing the four pinions 504 to slide on the fixed gear ring 503. Since the thickness of the pinions 504 is greater than the length of the teeth of the fixed gear ring 503, the four pinions 504 will not disengage from the fixed gear ring 503. The eight drive wheels 507 clamp the seamless steel pipe through the elastic force of the four compression springs 509. At the same time, one end of the inner grinding brush 412 enters the interior of the seamless steel pipe to grind the interior of the seamless steel pipe. This facilitates fixing the seamless steel pipe inside the rotating ring 501, making it easier to process the seamless steel pipe, improving the convenience of processing the seamless steel pipe, and preventing the seamless steel pipe from moving automatically.
[0070] Because the worm gear 510 meshes with the worm 511, the eight drive wheels 507 do not rotate when the seamless steel pipe enters between them, allowing the seamless steel pipe to slide between them. This facilitates fixing the seamless steel pipe and prevents it from moving automatically.
[0071] When the threaded rod 403 rotates, it drives the drive gear 502 to rotate, which in turn drives the transmission gear ring 505 and the rotating ring 501 to rotate. Since the four small gears 504 mesh with the fixed gear ring 503, when the four small gears 504 rotate with the rotating ring 501, they will rotate, which will drive the connecting output shaft 512 to rotate, which will drive the worm gear 511 to rotate, which will drive the worm wheel 510 and the drive shaft 508 to rotate. This will cause the eight drive wheels 507 to rotate in the same way, which will drive the seamless steel pipe between the eight drive wheels 507 to move. At the same time, the seamless steel pipe will rotate with the rotating ring 501, which will facilitate the movement and rotation of the seamless steel pipe. This will facilitate the processing of the seamless steel pipe and make it easier to grind different parts of the interior and surface of the seamless steel pipe from all directions, thereby improving the convenience of rust removal of the seamless steel pipe.
[0072] When the seamless steel pipe moves, it will come into contact with the moving frame 401, thereby pushing the moving frame 401 to move. This will cause the sliding inner ring 404 to slide inside the threaded rod 403, thereby squeezing the elastic spring 409. When the seamless steel pipe moves in the opposite direction, the moving frame 401 and the sliding inner ring 404 will be reset by the elastic force of the elastic spring 409, thus facilitating the processing of the seamless steel pipe.
[0073] The external grinding mechanism 6 includes two fixed support frames 601, both of which are fixedly connected inside the rust removal box 1. Four external grinding rotating shafts 603 are rotatably connected inside the two fixed support frames 601. An external grinding brush 605 is fixedly sleeved on each of the four external grinding rotating shafts 603. A grinding drive gear 604 is fixedly sleeved on each of the four external grinding rotating shafts 603. A rotating gear ring 602 is fixedly installed on one side of the rotating ring 501. All four grinding drive gears 604 are meshed with the rotating gear ring 602.
[0074] When the rotating ring 501 rotates, it drives the rotating gear ring 602 to rotate, which in turn drives the four grinding drive gears 604 to rotate, which in turn drives the four external grinding rotating shafts 603 and the four external grinding brushes 605 to rotate. The rotation of the four external grinding brushes 605 allows them to grind the exterior of the seamless steel pipe, thus facilitating simultaneous grinding of the inner and outer walls of the seamless steel pipe, improving the convenience of grinding the seamless steel pipe, and increasing the speed of rust removal.
[0075] Since the diameter of the rotating gear ring 602 is larger than the diameter of the grinding drive gear 604, the rotating gear ring 602 drives the grinding drive gear 604 to accelerate, thereby increasing the rotation speed of the outer grinding brush 605 and thus increasing the rust removal speed.
[0076] The pipe receiving device includes a square rod 702, which is fixedly connected inside the rust removal box 1. A movable block 703 is slidably connected to the surface of the square rod 702. A rotating roller 704 is rotatably connected to one side of the movable block 703. The second exhaust hose 309 is in contact with the surface of the rotating roller 704. A return spring 701 is movably sleeved on the surface of the square rod 702. The end of the return spring 701 near the movable block 703 is fixedly connected to the movable block 703, and the end of the return spring 701 away from the movable block 703 is fixedly connected to the inner wall of the rust removal box 1.
[0077] When the movable air outlet hollow ring 307 moves, it pulls the second exhaust hose 309, which in turn pulls the rotating roller 704, causing the moving block 703 to slide on the surface of the square rod 702 and press against the return spring 701. When the movable air outlet hollow ring 307 moves in the opposite direction, the second exhaust hose 309 stops pressing against the rotating roller 704, and the moving block 703 is reset by the elastic force of the return spring 701. This facilitates the retraction of the second exhaust hose 309, improves the neatness of the second exhaust hose 309 inside the rust removal box 1, and prevents the second exhaust hose 309 from falling between the multiple external grinding brushes 605 and causing entanglement. This ensures the stable operation of the device and prevents the second exhaust hose 309 from getting tangled together and interfering with the device.
[0078] This device uses a single motor 407 to drive multiple mechanisms, thereby reducing device costs, lowering energy consumption, and enhancing the product's highlights and advantages.
[0079] Working principle:
[0080] The inner grinding brush 412 is inserted into the interior of the seamless steel pipe, and then the motor 407 is started, which drives the threaded rod 403 to rotate, which in turn drives the sliding inner ring 404 to rotate. Then, through the two sliding inner rings 404 and the belt 411, the rotating grinding rod 402 is rotated. Then, through the rotation of the rotating grinding rod 402, the inner grinding brush 412 is rotated, which in turn causes the inner grinding brush 412 to grind and remove rust from the inner wall of the seamless steel pipe.
[0081] The negative pressure fan 201 is activated, drawing air from the suction pipe 202. This draws the gas inside the residue handling box 204 into the negative pressure fan 201, creating a strong negative pressure inside the residue handling box 204. This negative pressure then draws air from the suction hose 206, and further from the interior of the connecting box 207. The suction connecting pipe 210 and the suction baffle 208 are also subjected to negative pressure suction, allowing the gas inside the seamless steel pipe to enter the rotating grinding rod 402 through the suction port 211 on the suction disc 209. The suction baffle 208 draws in air, and the powerful suction draws the polishing residue through the suction port 211 into the rotating polishing rod 402. The residue enters the suction baffle 208, the suction connecting pipe 210, and the connecting box 207, then the suction hose 206, and finally the residue treatment box 204. This facilitates the collection and treatment of residue inside the seamless steel pipe, preventing impurities from accumulating inside the seamless steel pipe and minimizing the accumulation of residue inside the seamless steel pipe.
[0082] When air is drawn into the residue treatment box 204, impurities inside the rust removal box 1 are drawn into the residue treatment box 204 through the suction box 212 and connecting pipe 203, which facilitates the treatment of the residue inside the rust removal box 1. The residue drawn into the residue treatment box 204 is filtered through the filter screen 213, and the filtered air enters the suction pipe 202, which facilitates the treatment of the air drawn into the negative pressure fan 201, thereby minimizing the entry of impurities into the negative pressure fan 201.
[0083] The negative pressure fan 201 draws in the gas and delivers it into the interior of the heating connection box 306. The gas is heated by the heating wire inside the heating connection box 306, and then delivered into the interior of the first exhaust hose 301. The gas is then delivered into the cavity inside the connection box 207 through the first exhaust hose 301, and then into a cavity formed by the partition 305 and the suction baffle 208 through the exhaust connection pipe 302. Finally, the gas is discharged through the exhaust port 304. Since the exhaust port 304 rotates with the rotating grinding rod 402, it is convenient to dry the interior of the seamless steel pipe from multiple angles.
[0084] When the threaded rod 403 rotates, the movable air outlet hollow ring 307 is restricted by the limiting slide rod 408, causing the movable air outlet hollow ring 307 to move. This movement of the air outlet 308 and the movable air outlet hollow ring 307 allows the heated air inside the heating connection box 306 to enter the second exhaust hose 309 and then the movable air outlet hollow ring 307, which is then discharged through the air outlet 308. Simultaneously, the movement of the movable air outlet hollow ring 307 dries the outer wall of the seamless steel pipe.
[0085] The seamless steel pipe moves between the eight drive wheels 507, which causes the four drive wheels 507 to squeeze together, which in turn causes the four sliding frames 506 to slide inward into the rotating ring 501 and squeeze the four compression springs 509, which in turn causes the four connecting output shafts 512 to slide outward, which in turn causes the four pinions 504 to slide on the fixed gear ring 503. Since the thickness of the pinions 504 is greater than the length of the teeth of the fixed gear ring 503, the four pinions 504 will not disengage from the fixed gear ring 503, and the eight drive wheels 507 clamp the seamless steel pipe by the elastic force of the four compression springs 509.
[0086] When the threaded rod 403 rotates, it drives the drive gear 502 to rotate, which in turn drives the transmission gear ring 505 and the rotating ring 501 to rotate. Since the four pinions 504 mesh with the fixed gear ring 503, when the four pinions 504 rotate with the rotating ring 501, they will rotate, which will drive the connecting output shaft 512 to rotate, which will drive the worm 511 to rotate, which will drive the worm wheel 510 and the drive shaft 508 to rotate, which will cause the eight drive wheels 507 to rotate in the same way, which will drive the seamless steel pipe between the eight drive wheels 507 to move. At the same time, the seamless steel pipe rotates with the rotating ring 501, which facilitates the movement and rotation of the seamless steel pipe.
[0087] When the rotating ring 501 rotates, it drives the rotating gear ring 602 to rotate, which in turn drives the four grinding drive gears 604 to rotate, which in turn drives the four external grinding rotating shafts 603 and the four external grinding brushes 605 to rotate. The rotation of the four external grinding brushes 605 causes the four external grinding brushes 605 to grind the exterior of the seamless steel pipe.
[0088] When the movable air outlet hollow ring 307 moves, it pulls the second exhaust hose 309, which in turn pulls the rotating roller 704 to move. This causes the moving block 703 to slide on the surface of the square rod 702 and press against the return spring 701. When the movable air outlet hollow ring 307 moves in the opposite direction, the second exhaust hose 309 stops pressing against the rotating roller 704, and the moving block 703 is reset by the elastic force of the return spring 701, which facilitates the retraction of the second exhaust hose 309.
