Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of chromium-plated superconducting wire processing and detection, in particular to a chromium-plated superconducting wire processing and detection device and a detection method thereof. BACKGROUND

[0002] The chromium-plated superconducting wire processing and detection device is a professional device for detecting the quality of chromium-plated superconducting wire. The chromium-plated superconducting wire has a chromium layer plated on the surface of the superconducting wire to improve its hardness, wear resistance, corrosion resistance, and electrical properties. Such wire has a wide range of applications in the fields of electric power and magnetic levitation, and therefore, the quality thereof is extremely high. The corrosion resistance test is one of the important means for evaluating the corrosion resistance of the chromium-plated layer. The salt spray test can be used to test the corrosion resistance of the chromium-plated layer, and the salt spray test chamber is a device for evaluating and testing the corrosion resistance of products or metal materials by artificially simulating the salt spray environment in the chamber.

[0003] In the prior art, a salt spray tester disclosed in CN212586211U includes a test chamber, a spraying mechanism, and a placing mechanism. The spraying mechanism and the placing mechanism are arranged inside the test chamber. The placing mechanism includes a placing plate arranged in the test chamber and a plurality of support columns. The placing plate is horizontally arranged in the test chamber. Each support column is vertically and spacedly arranged on the placing plate. The upper end of each support column is provided with at least one limiting column. The outer diameter of each limiting column gradually decreases in the upward direction. The support column and the limiting column have the same axis. The test surface of the test product forms a certain angle with the vertical direction.

[0004] However, in actual use, the sprayed salt mist is generally not allowed to be recycled. Even if the sprayed salt mist in the spraying pipe is guided by the guide cover, the salt mist still spreads, but the salt water droplets may still flow back to the spraying pipe, causing mixing of the salt water solution, which is not conducive to the accuracy of the detection data and affects the experimental results.

[0005] Therefore, the present application provides a chromium-plated superconducting wire processing and detection device and a detection method thereof to solve the problem that the sprayed salt mist in the conventional salt spray tester flows back to the spraying pipe, causing pollution of the salt water solution and affecting the accuracy of the detection data. The sprayed salt mist can be collected separately to avoid flowing back to the salt water tank, and the spraying pipe can be self-cleaned to remove salt scale on the wall surface and avoid blocking the pipeline.

[0046] Embodiment two, refer to the attached Figures 1-18 On the basis of embodiment one, in order to realize the integration of the salt mist detection mechanism and the waste mist collection mechanism, the assembly and disassembly of the two are facilitated.

[0048] In the embodiment, the threaded sleeve 31 is threadedly connected with the upper end of the spray outer tube 3, and the fixed cylinder seat 51 is limited by the limiting member. An annular embedding groove 3110 is formed on the upper surface of the upper support ring plate 311, and an embedding block 3111 connected with the bottom of the fixed cylinder seat 51 forms preliminary limiting. At this time, the fixed cylinder seat 51 is assembled with the top of the spray inner tube 5 by rotating the fixed cylinder seat 51. The limiting member can support the installation of the fixed cylinder seat 51, and can connect the connecting wall cylinder 32 and the auxiliary wall scraping member and the like. A spiral groove 5100 is formed on the side wall of the salt mist flow cavity 510, so as to guide the salt mist sprayed by the spray inner tube 5. It is worth noting that the additional buffer member can ensure that the plugging plug column 53 and the lifting disc 532 avoid the impact on the top of the lifting disc 532 during the lifting process. The stable guidance of the lifting disc 532 is realized by the cooperation of the guide column 533 and the abutting elastic wire 5331. When the plugging plug column 53 and the lifting disc 532 are not pushed, the plugging plug column 53 and the lifting disc 532 are reset by the reverse elastic force of the abutting elastic wire 5331, and the discharge hole 5102 is plugged.

[0049] Embodiment three, refer to the attached Figures 1-18 On the basis of embodiment two, in order to realize the vertical movement of the plugging plug column 53 and the horizontal rotation, the inner tube rotating member is driven to rotate:

The outer side surface of the plugging plug column 53 is fixedly provided with a guide vane 530, and the guide vane 530 is arranged in multiple groups and circularly arranged about the center axis of the plugging plug column 53.

[0051] In the embodiment, refer to Figure 6 and Figure 11As shown, when the salt mist in the spray inner tube 5 is sprayed upward, the salt mist will first drive the blocking plug column 53 to move upward, and the lifting disc 532 moves inside the activity groove 5101. When the salt mist spray pressure reaches a certain degree, the salt mist can be guided through the inclined distribution of the guide vane plate 530 on the surface of the blocking plug column 53 and the design of the spiral groove 5100. The blocking plug column 53 will rotate under the continuous pushing action of the salt mist, which can accelerate the flow speed of the salt mist in the salt mist flow chamber 510, and at the same time, trigger the inner tube rotating part to disturb the salt mist in the inner cavity of the spray inner tube 5. It should be noted that after the blocking plug column 53 and the lifting disc 532 are lifted, the guide hole 5102 is communicated with the salt mist flow chamber 510. At this time, the salt mist is discharged to the buffer chamber 5103 through multiple groups of guide holes 5102, and the salt mist is uniformly distributed and sprayed, guiding the spray to spread evenly around.

[0052] Embodiment four, refer to the attached Figures 1-18 On the basis of embodiment three, in order to realize the delicate degree of salt mist spraying, avoid the salt mist from top to bottom to form large water droplets directly falling on the wire surface to affect the detection result:

[0053] The upper outer surface of the fixed cylinder seat 51 is fixedly installed with a fixed sleeve ring 511. The outer surface of the fixed sleeve ring 511 is threadedly connected with an adapter seat 512. The upper end of the adapter seat 512 is fixedly installed with a conical flow guide cover 513. The outer wall of the conical flow guide cover 513 is uniformly provided with a flow guide groove 5130. The inner side of the adapter seat 512 and the outer side of the fixed cylinder seat 51 form a buffer chamber 5103. The inner wall of the adapter seat 512 is provided with a salt mist segmentation part. The salt mist segmentation part comprises a spray sub-pipe 5121. The spray sub-pipe 5121 is throughly connected with the inner wall of the buffer chamber 5103. The inner wall of the spray sub-pipe 5121 is fixedly installed with a rice-shaped frame 5122.

[0054] In this embodiment, the fixed sleeve ring 511 connected to the upper outer ring of the fixed cylinder seat 51 is threadedly connected between the fixed sleeve ring 511 and the adapter seat 512. At this time, the adapter seat 512 is assembled. In order to make the salt mist sprayed from the buffer chamber 5103 to the spray sub-pipe 5121 through the arrangement of the rice-shaped frame 5122, the salt mist can be further segmented into multiple small units, the uniformity of the salt mist distribution in the salt mist tester body 1 is increased, and the accuracy of the chromium-plated superconducting wire corrosion resistance detection is further improved. It should be noted that the length of the spray sub-pipe 5121 exceeds the outer wall of the adapter seat 512, which can block the salt water flowing down the flow guide groove 5130 to avoid backflow. It is worth noting that, as shown in the figure, Figure 6 As shown, the maximum diameter of the adapter seat 512 is smaller than the inner diameter of the upper support ring plate 311, so that the salt water flowing down can quickly enter the connecting wall cylinder 32 for collection.
