Description

Technical Field

[0001] This invention relates to the field of defect detection, and more specifically, to a device for detecting wear-resistant ceramic composite pipe texture. Background Technology

[0002] Wear-resistant ceramic composite pipes, simply put, are metal pipes (usually stainless steel or carbon steel) with a layer of high-hardness, high-wear-resistant ceramic material "embedded" or "coated" on the inner wall, thus combining the mechanical strength of metal pipes with the excellent wear resistance of ceramics.

[0003] To ensure the safety of wear-resistant ceramic composite pipes after production, specialized crack detection equipment is often required to inspect their internal structure. Currently, ultrasonic testing is commonly used to detect internal cracks. For example, existing technology (Chinese invention patent application CN118706941A) discloses a crack detection device for wear-resistant ceramic composite pipes. This device drives an ultrasonic testing probe into the pipe and then uses an intermittent moving detection mechanism to drive the ultrasonic testing probe to rotate once inside the wear-resistant ceramic composite pipe. Although it can detect the inside of the wear-resistant ceramic composite pipe, this detection method is a non-contact ultrasonic pulse echo detection method. Due to the scattering of the ceramic itself, the reflection of the multi-layer interface of the inner lining, and the unstable coupling, the crack echo is often submerged by background noise. Under the dual effects of attenuation and scattering, the echo signal is often submerged in noise, making it difficult to distinguish microcracks and reliably detect them, resulting in low detection accuracy. Summary of the Invention

[0004] In view of the problems existing in the prior art, the purpose of this invention is to provide a wear-resistant ceramic composite pipe texture detection device.

[0007] It also includes an outer detection unit connected to the upper end of the support platform, and the outer detection unit includes an eddy current detection probe and a lifting assembly fixed to the upper end of the support platform and driving the eddy current detection probe to rise and fall.

[0008] Both side seats one and side seats two are rotatably connected to a follower part, and the follower part is sealed and sleeved at both ends of the tube body and rotates synchronously with the tube body. A rotary joint is fixed to the other side of side seat one. The inner tube of the rotary joint passes through side seat one and the follower part to deliver coupling agent into the tube.

[0009] One side of the second side seat is connected to an inner layer detection unit, which includes a second movable seat, an electric push rod one fixed to one side of the second movable seat, a base plate fixed to the telescopic end of the electric push rod one, and an ultrasonic phased array probe fixed to the lower end of the base plate.

[0015] Furthermore, one of the disc bodies and the sealing gaskets are provided with drainage ports, the second side seat is provided with a drainage channel, and one side of the second side seat is provided with a pipe interface connected to the drainage channel. The lower end of the support platform is connected to a coupling fluid regulating assembly, which includes a pump body one fixed to one side of the support platform, a filter part and a storage tank fixed to the lower end of the support platform, and a second pump body fixed to the lower end of the support platform.

[0020] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0021] (1) This scheme adopts a combination of outer layer detection and inner layer detection. Eddy current detection is used to detect surface and near-surface cracks of the metal substrate, and phased array ultrasonic detection with coupling medium is used to detect internal ceramic layer cracks. It can focus and penetrate into the interior of the ceramic composite layer to detect ceramic layer cracks, delamination, voids, and ceramic interface bonding quality, which greatly improves the defect detection rate and detection accuracy.

[0022] (2) This solution is equipped with a coupling fluid adjustment component. By circulating and purifying the coupling fluid in the tube, suspended particles and impurities in the coupling fluid can be removed. The acoustic impedance matching between the coupling medium (mist water or water film) and the tube wall is more uniform, the ultrasonic energy transmission loss is reduced, the echo signal is stronger and more stable, and the particles are avoided from depositing or forming bubble clusters in the coupling medium during long-term detection. This effectively prevents sudden signal attenuation. The circulating purification ensures that the turbidity of the medium is the same during each detection, eliminating signal drift caused by medium aging or contamination.

[0023] (3) This solution is equipped with a tube wall bubble removal component. When the supporting and driving part drives the tube body to rotate, the silicone scraper can contact the inner wall of the ceramic layer inside the tube. The silicone scraper "scrapes" the bubbles attached to the microstructure on the inner wall of the ceramic layer to the flowing liquid layer. The circulating pump can suck away the liquid at the bottom of the coupling liquid through the liquid extraction port at the bottom of the plate body. A local flow field facing the liquid extraction port will be formed in the pit on the inner wall, generating sufficient shear force to "pull" the bubbles out from the bottom of the pit and into the liquid extraction channel. This avoids the stubborn bubbles in the deep pit that cannot be removed by the silicone scraper alone. It eliminates the local impedance change caused by the "gas-liquid-solid" three-phase mixing of the sound wave and the ceramic / water interface, ensuring that the probe and the tube wall are always in complete "water film contact", eliminating coupling failure and signal jitter. The continuous and uniform coupling layer makes the phased array focusing depth and beam direction stable and controllable, avoiding imaging shift or distortion caused by local bubbles, and making the detection results more reliable.

[0037] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0038] Please see Figures 1 to 11 A wear-resistant ceramic composite pipe texture detection device includes a support platform 1, a support and drive part 2 connected to the upper end of the support platform 1 to support the pipe body and drive the pipe body to rotate, and side seat 4 and side seat 5 connected to the upper end of the support platform 1 and capable of translational movement.

[0039] It also includes an outer detection unit 3 connected to the upper end of the support platform 1, and the outer detection unit 3 includes an eddy current detection probe 35 and a lifting assembly fixed to the upper end of the support platform 1 and driving the eddy current detection probe 35 to rise and fall.

[0040] One side of both side seat 4 and side seat 5 is rotatably connected to a follower part 6, and the follower part 6 is sealed and sleeved at both ends of the tube body and rotates synchronously with the tube body. The other side of side seat 4 is fixedly connected to a rotary joint 41, and the inner tube 781 of the rotary joint 41 passes through side seat 4 and follower part 6 to deliver coupling agent into the tube.

[0041] One side of the second side seat 5 is connected to the inner layer detection unit 8, and the inner layer detection unit 8 includes a second movable seat 81, an electric push rod 82 fixed to one side of the second movable seat 81, a base plate 83 fixed to the telescopic end of the electric push rod 82, and an ultrasonic phased array probe 84 fixed to the lower end of the base plate 83. The other side of the second side seat 5 is connected to a second displacement component 7, which is fixed to the second movable seat 81 and drives the second movable seat 81 to move in translation.

[0042] The supporting and driving part 2 includes two seats 21 connected to the upper end of the support platform 1, two grooves 22 respectively opened on the upper end of the two seats 21, a plurality of rotating rollers 23 rotatably connected to the two seats 21 and extending into the grooves 22, and a driving part 24 respectively fixed to one side of the two seats 21 for driving one of the rotating rollers 23 in the two seats 21 to rotate; the supporting and driving part 2 also includes a lead screw 29 rotatably connected to the inside of the support platform 1 and screwed to the inside of the two seats 21, a synchronous pulley 28 rotatably connected to the inside of the support platform 1 and fixed to one end of the lead screw 29, a synchronous pulley 26 rotatably connected to the lower end of the support platform 1, a synchronous belt 27 that drives the synchronous pulley 26 and the synchronous pulley 28 to connect, and a motor 25 fixed to the lower end of the support platform 1, with the output shaft of the motor 25 fixed to the synchronous pulley 26.

[0043] The lifting assembly includes a frame 31 fixed to the upper end of the support platform 1, a hydraulic cylinder 32 fixed to the upper end of the frame 31, a pressure seat 33 fixed to the telescopic end of the hydraulic cylinder 32, two flanges 34 integrally formed on the lower end of the pressure seat 33, and a plurality of rotating rollers 36 rotatably connected to the lower ends of the two flanges 34. The eddy current detection probe 35 is fixed to the lower end of the pressure seat 33 and located between the two flanges 34.

[0044] The support platform 1 is connected to two shifting components 11 that drive the side seat 4 and the side seat 5 to perform translational movements. The shifting component 11 includes two movable slots 111 symmetrically opened on the upper end of the support platform 1, a lead screw 112 rotatably connected in one of the movable slots 111, and a motor 113 fixed to one side of the support platform 1 with its output shaft fixed to one end of the lead screw 112. The lower ends of the side seat 4 and the side seat 5 are slidably connected in the two movable slots 111, and the lead screw 112 is screwed into the side seat 4 and the side seat 5.

[0045] The follower part 6 includes a disc 61 rotatably connected to one side of side seat 4 and side seat 5, a sealing ring 62 and a sealing gasket 63 connected to the inner wall of the disc 61, and a clamping member 64 connected inside the disc 61 and pressing the sealing ring 62 against the outer surface of the tube.

[0046] The shifting assembly 7 includes a frame 71 fixed to one side of the side seat 5, a slider 75 fixed to the lower end of the frame 71, a slide rail 76 slidably connected to the lower end of the slider 75, a guide rod 72 with one end fixed to the inner wall of the frame 71 and the other end fixed to the side seat 5, a lead screw 73 with one end rotatably connected to the inner wall of the frame 71 and the other end rotatably connected to the side seat 5, a motor 74 fixed to one side of the frame 71 and with its output shaft fixed to one end of the lead screw 73, a movable seat 77 movably sleeved outside the guide rod 72 and screwed outside the lead screw 73, and a column 78 fixed inside the movable seat 77. One end of the column 78 passes through the side seat 5 and the disc 61 and is fixed to one side of the movable seat 81. A wire 782 for providing electrical energy required for the operation of the inner layer detection part 8 is provided inside the column 78.

[0047] By adopting the above technical solution, controlling the operation of motor 25 can drive synchronous pulleys 26 and 28 to rotate. The rotation of synchronous pulley 28 can drive screw 29 to rotate. The rotation of screw 29 can cause the two seats 21 to move towards each other or away from each other, which facilitates the adjustment of the distance between the two seats 21 according to the length of the ceramic composite tube. After the position of the seats 21 is adjusted, the ceramic composite tube is placed in the grooves 22 of the two seats 21. The hydraulic cylinder 32 is controlled to work and drive the pressure seat 33 to descend, so that the rollers 36 at the lower end of the two flanges 34 press against the outer surface of the upper end of the composite tube. At the same time, the eddy current detection probe 35 is close to the outer surface of the composite tube, and the two motors 113 are controlled to work and drive the two screws 112 to rotate respectively. The rotation of lead screw 112 drives side seat 4 and side seat 5 to move towards both ends of the composite tube, allowing the disc 61 on one side of side seat 4 and side seat 5 to fit over the ends of the composite tube. The ends of the composite tube are in contact with the sealing gaskets 63 inside the two discs 61. The sealing rings 62 are pressed against the outside of both ends of the composite tube by the clamping element 64. (During the process of the disc 61 fitting over the ends of the composite tube, the sealing rings 62 on the inner wall of the disc 61 can fit against the outer surface of the composite tube, achieving a sealing effect. The clamping element 64 is used to increase the friction between the sealing rings 62 and the outside of the composite tube, which improves the sealing effect and facilitates the synchronous rotation of the disc 61 with the composite tube. The clamping method used by the clamping element 64 is as follows: on the disc...) Multiple arc-shaped pressure rings are movably arranged inside the disc body 61. One side of the arc-shaped pressure ring is in contact with the sealing ring 62, and the other side of the arc-shaped pressure ring is rotatably connected to a threaded column. The threaded column is screwed into the disc body 61. By rotating the threaded column, the arc-shaped pressure ring can apply force to the sealing ring 62. This method is a common arc-shaped clamping method in the mechanical field and will not be elaborated here. When both disc bodies 61 are fitted outside the two ends of the composite tube, coupling fluid is introduced into the composite tube through the rotary joint 41. The electric push rod 82 is controlled to work and drive the base plate 83 to descend, so that the ultrasonic phased array probe 84 is close to the inner wall of the composite tube. Then, the two drive units 24 are controlled to work simultaneously to drive the rotating roller 23 to rotate. (The drive unit 24 is a drive component composed of a motor, reducer, etc.) (Given mature technology, controlling two motors to work synchronously is a common practice in existing technologies, which will not be elaborated upon here.) When the rotating roller 23 rotates, it drives the composite tube to rotate within the groove 22. The eddy current detection probe 35 detects cracks in the outer metal layer of the composite tube, while the ultrasonic phased array probe 84, coupled with a coupling fluid, detects cracks in the inner ceramic layer. Both eddy current detection and ultrasonic phased array detection are mature existing technologies, and will not be elaborated upon here. After driving the composite tube to rotate 360°, the control motor 74 rotates, driving the movable seat 77 and the column 78 to move. The movement of the column 78 drives the movable seat 81 to translate. The translational movement of the movable seat 81 inside the composite tube changes the position of the ultrasonic phased array probe 84.A comprehensive inspection of the ceramic layer of the composite pipe is performed. Eddy current testing is used to detect surface and near-surface cracks in the metal substrate, while phased array ultrasonic testing with a coupling medium is used to detect internal ceramic layer cracks. This focused approach penetrates deep into the ceramic composite layer, detecting cracks, delamination, voids, and the bonding quality of the ceramic interface, significantly improving the defect detection rate and accuracy.

[0048] like Figure 1 , Figure 3 , Figures 6-8 As shown, both the disc body 61 and the sealing gasket 63 have drainage ports 51 inside. The side seat 2 5 has a drainage channel 53 inside, and a pipe interface 52 connected to the drainage channel 53 is opened on one side of the side seat 2 5. The lower end of the support platform 1 is connected to a coupling fluid regulating assembly 9, which includes a pump body 1 91 fixed to one side of the support platform 1, a filter part 92 and a liquid storage tank 93 fixed to the lower end of the support platform 1, and a pump body 2 94 fixed to the lower end of the support platform 1. The input end of the pump body 1 91 is connected to the pipe interface 52, and the output end is connected to the input end of the filter part 92. The input end of the liquid storage tank 93 is connected to the output end of the filter part 92, and the output end is connected to the input end of the pump body 2 94. The output end of the pump body 2 94 is connected to the input end of the rotary joint 41.

[0049] By adopting the above technical solution, when the tube body and the disc body 61 rotate... Figure 6 After the drain port 51 on the middle plate 61 is rotated 180°, the drain port 51 can move downwards. At this time, the coupling fluid in the pipe can enter the drain channel 53 through the drain port 51, and then be discharged from the pipe interface 52 and enter the pump body 91. The pump body 91 operates to pump the coupling fluid into the filter section 92. After the particulate matter and impurities in the coupling fluid are filtered out by the filter section 92, it is discharged from the filter section 92 and enters the storage tank 93 (new coupling fluid can also be added to the storage tank 93 separately to ensure that the coupling fluid is sufficient). The pump body 94 operates to pump the coupling fluid in the storage tank 93. The fluid is pumped into the rotary joint 41 and discharged from the rotary joint 41 back into the tube. By circulating and purifying the coupling fluid in the tube, suspended particles and impurities in the coupling fluid can be removed. The acoustic impedance matching between the coupling medium (mist water or water film) and the tube wall is more uniform, the ultrasonic energy transmission loss is reduced, and the echo signal is stronger and more stable. This avoids the deposition of particles or the formation of bubble clusters in the coupling medium during long-term detection, effectively preventing signal attenuation and sudden changes. The circulating purification ensures that the turbidity of the medium is the same for each detection, eliminating signal drift caused by medium aging or contamination.

[0050] like Figure 6 , Figure 10 and Figure 11As shown, the lower end of the base plate 83 is also connected to a pipe wall cleaning assembly 12, which includes a base 121 fixed to the lower end of the base plate 83, a silicone scraper 122 and a plate body 123 fixed to the lower end of the base 121, multiple liquid extraction ports 124 opened at the lower end of the plate body 123, a flow channel opened inside the plate body 123 and connected to the multiple liquid extraction ports 124, a circulation pump 125 fixed to one side of the plate body 123, a microporous mesh 127 fixed to the lower end of the plate body 123, and a liquid delivery pipe 126 passing through the interior of the base plate 83. The output end of the circulation pump 125 is connected to one end of the liquid delivery pipe 126, and the input end is connected to the flow channel. The other end of the liquid delivery pipe 126 passes through the base plate 83 and extends into the microporous mesh 127.

[0051] By adopting the above technical solution, when the electric push rod 82 drives the base plate 83 to move downward, the bottom of the silicone scraper 122 can contact the inner wall of the composite tube. When the supporting drive part 2 drives the composite tube to rotate, the silicone scraper 122 can "scrape off" the air bubbles attached to the microstructure on the inner wall of the ceramic layer into the flowing liquid layer. At the same time, the circulating pump 125 can suck away the liquid at the bottom of the coupling liquid through the liquid extraction port 124 at the bottom of the plate 123. This will form a local flow field facing the liquid extraction port 124 in the pit on the inner wall, generating sufficient shear force. When the silicone scraper 122 cannot remove the air bubbles in the pit on the inner wall, the air bubbles are "pulled" out from the bottom of the pit by liquid extraction and enter the liquid extraction channel, avoiding the inability of the silicone scraper 122 to remove the air bubbles in the deep pit. The stubborn bubbles eliminate the local impedance abrupt change caused by the "gas-liquid-solid" three-phase mixing of the sound wave and the ceramic / water interface, ensuring that there is always a complete "water film contact" between the probe and the tube wall, eliminating coupling failure and signal jitter. The continuous and uniform coupling layer makes the focusing depth and beam direction of the phased array stable and controllable, avoiding imaging offset or distortion caused by local bubbles, and making the detection results more reliable. The coupling liquid drawn out by the circulation pump 125 is discharged from the other end of the liquid delivery pipe 126. When the discharged coupling liquid passes through the microporous mesh 127 (which can be a polytetrafluoroethylene PTFE hydrophobic membrane or a ceramic microporous plate), the liquid can penetrate through the membrane pores. The bubbles are trapped on the outside of the membrane due to surface tension, which can separate the bubbles and prevent the bubbles drawn from the bottom of the coupling liquid from reaching the vicinity of the ultrasonic phased array probe 84 again.

[0052] like Figure 6 and Figure 9As shown, the movable seat 2 81 is also connected to an internal cleaning assembly 10. The internal cleaning assembly 10 includes an electric push rod 2 101 fixed to one side of the movable seat 2 81, a top plate 102 fixed to the telescopic end of the electric push rod 2 101, a sanding roller 105 and a brush roller 106 rotatably connected to the inner wall of the top plate 102, a plurality of nozzles 103 fixed to the upper end of the top plate 102, and a drive part 2 104 fixed to one side of the top plate 102 and driving the sanding roller 105 and the brush roller 106 to rotate. An inner tube 781 for providing water to the nozzles 103 is provided inside the column 78.

[0053] One side of the top plate 102 and the bottom plate 83 are both fixedly connected to a guide post 85, and the other end of the guide post 85 is movably inserted into the interior of the movable seat 81.

[0054] By adopting the above technical solution, before performing ultrasonic phased array testing inside the pipe, the extension of the electric push rod 101 can drive the top plate 102 to rise. The rise of the top plate 102 can make the grinding roller 105 and the brush roller 106 contact the inner wall of the composite pipe, thereby grinding the inner wall of the ceramic layer of the composite pipe. At the same time, the nozzle 103 can spray coolant onto the grinding area to grind the uneven parts of the inner wall of the ceramic layer, making the inner wall of the ceramic layer smooth and avoiding damage to the ultrasonic phased array probe 84 caused by unevenness. This also avoids changes in the ultrasonic emission angle and focus shift caused by unevenness, which could lead to misjudgment or error. In addition, the surface smoothness is improved after grinding. With the help of coupling fluid, it helps to form a continuous and uniform acoustic coupling layer. After cleaning, the geometric reflection surface of the crack front edge is clearer, enhancing the contrast of ultrasonic reflection echo and making the defect boundary clearer.

[0055] Instructions for use: Place the ceramic composite tube in the grooves 22 of the two seats 21. Control the hydraulic cylinder 32 to work and drive the pressure seat 33 to descend, so that the rollers 36 at the lower ends of the two flanges 34 press against the outer surface of the upper end of the composite tube. At the same time, the eddy current detection probe 35 is close to the outer surface of the composite tube. Control the shifting component 11 to work and drive the side seats 4 and 5 to move towards both ends of the composite tube, so that the disc 61 on one side of the side seats 4 and 5 can be fitted over the outside of both ends of the composite tube. Inject coupling fluid into the composite tube through the rotary joint 41. Control the electric push rod 82 to work and drive the base plate 83 to descend, so that the ultrasonic phased array probe 84 is close to the outer surface of the composite tube. The inner wall of the composite tube is then controlled by two drive units 24 working simultaneously to drive the rotating roller 23 to rotate. When the rotating roller 23 rotates, it can drive the composite tube to rotate in the groove 22. The outer metal layer of the composite tube is cracked by the eddy current detection probe 35, and the inner ceramic layer of the composite tube is cracked by the ultrasonic phased array probe 84 with coupling fluid. The rotation of motor 74 drives the movable seat 77 and the column 78 to move. The movement of the column 78 can drive the movable seat 81 to translate. The translation of the movable seat 81 inside the composite tube can change the position of the ultrasonic phased array probe 84, so as to perform a comprehensive inspection of the ceramic layer of the composite tube.
