[0041] Working principle of the present invention:

[0042] During operation, when the low-carbon steel pipe is manually placed on the roller 2305, the manual control system controls the cylinder rod of the cylinder 2301 to extend, and the cylinder rod drives the mounting plate 2302 to move toward the axial direction of the inner tube 22, and the mounting plate 2302 drives the roller 2305 to move until the low-carbon steel pipe is clamped. At this time, the worm wheel 2309 rolls on the worm 2310, and the first motor 2307 is controlled to start, and the first motor 2307 drives the second rotating shaft 2308 to rotate, and the second rotating shaft 2308 drives the belt 2306 to rotate, and the belt 2306 drives the first rotating shaft 2304 to rotate, and the first rotating shaft 2304 drives the roller 2 305 rotates, causing the mild steel pipe to move toward the direction approaching the transportation device 5. At the same time, the second rotating shaft 2308 drives the worm wheel 2309 to rotate, the worm wheel 2309 drives the worm 2310 to rotate, the worm 2310 drives the first bevel gear 2311 to rotate, the first bevel gear 2311 drives the second bevel gear 2312 to rotate, the second bevel gear 2312 drives the third rotating shaft 2314 to rotate, the third rotating shaft 2314 drives the gear 2315 to rotate, the gear 2315 rolls on the gear ring 25, drives the inner tube 22 to rotate in the outer tube 24, so that the mild steel pipe rotates, and the mild steel pipe can be transported while rotating.

[0043] The manual control system controls the third motor 43 to start, the third motor 43 drives the screw rod 44 to rotate, the screw rod 44 rotates, the screw rod 44 drives the horizontal plate 4101 to slide in the direction of the second cleaning device 42, the horizontal plate 4101 drives the vertical plate 4102 to move, the vertical plate 4102 drives the mounting block 4103 to move, and the mounting block 4103 drives the cleaning brush 4104 to move until the cleaning brush 4104 contacts the low carbon steel pipe. During the rotation of the low carbon steel pipe, impurities on the outer surface of the low carbon steel pipe are adsorbed on the cleaning brush 4104, and large impurities will be swept into the recycling box 4107.

[0044] When the low carbon steel pipe is transported to the transportation device 5, the control system controls the cylinder rod of the hydraulic cylinder 31 of the second inner wall cleaning device 6 to extend, the cylinder rod drives the lifting plate 32 to rise, the lifting plate 32 drives the support seat 33 to rise, the support seat 33 drives the disc 34 to rise, and the disc 34 drives the hollow pipe 36 to rise until the hollow pipe 36 and the transportation device 5 are on the same axis, and controls the second motor 35 to start, the second motor 35 drives the fourth rotating shaft 37 to rotate, the fourth rotating shaft 37 drives the circular plate 3802 to rotate, the circular plate 3802 drives the slider 3803 to rotate, the cylinder of the slider 3803 slides in the arc groove 3805, and the cylinder drives the slider 3803 to slide in the sliding groove away from the fourth rotating shaft 37 until the extending device 38 has the same inner diameter as the low carbon steel pipe.

[0045] When the inner diameter of the extending device 38 is the same as that of the low-carbon steel pipe, the transport device 5 transports the low-carbon steel pipe toward the second inner wall cleaning device 6, and the extending device 38 adsorbs the impurities in the pipe on the rubber block. When the low-carbon steel pipe is completely covered on the outer surface of the hollow pipe 36, the cylinder rod output of the hydraulic cylinder 31 of the first inner wall cleaning device 3 is controlled, and the cylinder rod drives the lifting plate 32 to rise, so that the hollow pipe 36 rises to the specified position. At the same time, the manual control control system controls the fan 4901 to start, and the jet pipe 4106 inhales air to adsorb the fine impurities on the cleaning brush 4104 into the filter box 4903. The filter plate in the filter tube 4906 is filtered and passes through the fan 4901, and finally is ejected from the hollow pipe 36 to blow off the impurities stuck to the inside of the pipe.

[0046] After jetting for a period of time, the fan 4901 is controlled to reverse, and at the same time, the first reversing valve 4902 and the second reversing valve 4904 switch the pipeline, and the hollow pipeline 36 inhales air, and the fine impurities inside the pipeline are adsorbed into the filter box 4903, and then enter the fan 4901 after being filtered by the filter plate in the filter tube 4906, and finally ejected from the jet pipe 4106, and the impurities adsorbed on the cleaning brush 4104 are blown into the recovery box 4107. After adsorption, the transport device 5 transports the low-carbon steel pipe in the opposite direction, and the scraper 3801 sprays the impurities from the hollow pipeline 36. The impurities are adsorbed, and when the low carbon steel pipe is transported out of the extending device 38, the cylinder rod of the hydraulic cylinder 31 is controlled to be retracted, and the cylinder rod drives the lifting plate 32 to descend, and the lifting plate 32 drives the hollow pipe 36 to descend and return to the initial position, and the transportation device 5 repeats the above steps to clean the inside of another part of the low carbon steel pipe. When all the cleaning is completed, the transportation device 5 is controlled to transport the low carbon steel pipe to the discharging device 8, and the ultrasonic detection ring 7 in front of the discharging device 8 performs flaw detection on the cleaned low carbon steel pipe, and the discharging device 8 transports the flaw-detected low carbon steel pipe out of the material.
