Description

Technical Field

[0001] This utility model relates to the field of stainless steel testing technology, specifically to a corrosion resistance testing device for stainless steel. Background Technology

[0002] By pouring acidic or alkaline liquids into a testing tank and immersing stainless steel parts in the liquids for a certain period of time before removing them, the resistance of stainless steel to acidic and alkaline corrosion environments is tested. The significance of this test is to provide a scientific basis for material selection in chemical, medical and other fields, to identify potential risks, to avoid equipment failures, safety accidents and economic losses caused by corrosion, and to ensure the stability of stainless steel performance and service life.

[0003] After the specified soaking time is completed, the parts need to be manually removed. At this time, some acidic and alkaline liquids will remain on the surface of the stainless steel parts.

[0028] Example 1

[0029] Please see Figures 1-2This utility model provides a corrosion resistance testing device for stainless steel, including a platform 1. An air purifier 3 is fixedly connected to the middle of the inner wall of the platform 1. Exhaust fans 7 are fixedly connected to the left and right sides of the front end of the platform 1. Immersion tanks 2 are fixedly connected to the left and right sides of the top of the platform 1. Hollow boxes 9 are fixedly connected to the upper front of the immersion tanks 2. Drain pipes 15 are fixedly connected to the opposite side of the bottom of the immersion tanks 2. A cover plate 11 is provided on the top of the immersion tanks 2. A top plate 17 is fixedly connected to the opposite end of the cover plate 11. Limiting blocks 13 are fixedly connected to the upper part of the opposite end of the immersion tanks 2. Guide rods 14 are slidably connected to the inner wall of the limiting blocks 13. The upper part of the opposite end of the guide rods 14 is fixedly connected to the opposite end of the cover plate 11. A hydraulic rod 16 is fixedly connected to the middle of the top of the platform 1. The driving end of the hydraulic rod 16 is fixedly connected to the bottom of the top plate 17. The inner wall of the cover plate 11 is rotatably connected to the middle of the cover plate 11. The bottom end of the cover plate 12 is fixedly connected to the opposite side of the slide frame 18. The inner wall of the slide frame 18 is slidably connected to the displacement block 24. The opposite end of the displacement block 24 is fixedly connected to the storage tube 19. The front and rear sides of the inner wall of the storage tube 19 are fixedly connected to the mesh 25. The bottom end of the storage tube 19 is provided with several holes 26. The inner wall of the displacement block 24 is threadedly connected to the threaded rod 23, which passes through the upper and lower sides of the displacement block 24. The bottom end of the displacement block 24 is rotatably connected to the inner wall of the bottom end of the slide frame 18. The bottom end of the cover plate 12 is located on the upper inner wall of the slide frame 18 and is fixedly connected to the motor 22. The drive end of the motor 22 is fixedly connected to the top end of the threaded rod 23. The top center of the cover plate 12 is fixedly connected to the rotating shaft 20. The top end of the rotating shaft 20 is fixedly connected to the rotating wheel 21.

[0030] Before the test begins, the equipment is in its initial closed state. First, the hydraulic rod 16 is activated. As the driving end of the hydraulic rod 16 moves upward, the top plate 17 rises under its push. The cover plates 11 connected to both sides of the top plate 17 also move accordingly. The guide rods 14 connected to the opposite ends of the cover plates 11 slide smoothly within the limiting blocks 13, playing a guiding and stabilizing role. When the cover plates 11 rise to the predetermined height, the driving end of the hydraulic rod 16 stops pushing. At this time, the operator injects appropriate amounts of acidic and alkaline test solutions into the two immersion tanks 2 respectively. The two test solutions with different properties will simulate different corrosion. In the corrosive environment, stainless steel workpieces of identical specifications and materials are placed in two storage cylinders 19. After preparation, the hydraulic rod 16 is controlled again to retract its drive end, and the top plate 17 drives the two side cover plates 11 to slowly return to their original positions. At this time, the storage cylinder 19 under the cover plate 11 is immersed in the test liquid. The mesh 25 and the holes 26 on the storage cylinder 19 allow the test liquid to fully penetrate and come into full contact with the stainless steel workpiece. Within the specified test time, the test liquid corrodes the stainless steel workpiece to test the stainless steel's resistance to different corrosive environments.

[0031] Example 2

[0032] Please see Figures 3-5 Further, based on Embodiment 1, a drive shaft 28 is rotatably connected to both the left and right sides of the top of the top plate 17. Gears 29 are fixedly connected to the outer walls of the drive shafts 28, and the gears 29 are meshed with each other. A second wheel 30 is fixedly connected to the top of the drive shafts 28. A concave frame 27 is fixedly connected to the front and rear sides of the drive shaft 28 on the left side of the top of the top of the top plate 17. A second motor 31 is fixedly connected to the top of the concave frame 27. The drive end of the second motor 31 passes through the inner wall of the concave frame 27 and is fixedly connected to the top of the second wheel 30 on the left side. A synchronous belt 32 is meshed with the opposite ends of the outer diameter of the second wheel 30. The inner diameters of the opposite ends of the synchronous belt 32 are meshed with the outer diameters of the opposite ends of the wheel 21. Several bent pipes 10 are fixedly connected to the top of the cavity box 9. The other ends of the bent pipes 10 penetrate the front end of the soaking tank 2 and are located on the upper inner wall of the cavity box 9. The bottom end of the cavity box 9 is fixedly connected with a guide pipe 8. The other end of the guide pipe 8 is fixedly connected to the input end of the exhaust fan 7. The outer side of the front end of the air purifier 3 is fixedly connected with a sealing cover 4. The front end of the sealing cover 4 is fixedly connected with an extension pipe 5. The left and right ends of the extension pipe 5 are fixedly connected with connecting pipes 6. The other end of the connecting pipe 6 is fixedly connected to the output end of the exhaust fan 7.

[0033] When the detection time reaches the set value, the stainless steel workpiece is removed from the detection liquid. At this time, two motors 22 are started simultaneously. The drive end of motor 22 drives the threaded rod 23 to rotate rapidly. Under the principle of threaded transmission, the displacement block 24 slides vertically upward in the slide frame 18, thereby driving the storage cylinder 19 to rise gradually. When the top of the storage cylinder 19 is tightly attached to the bottom of the adapter plate 12, motor 22 stops running, and the stainless steel workpiece is removed from the detection liquid. In order to avoid the residual detection liquid from continuing to react with the stainless steel and affecting the detection results, motor 31 is started. Its drive end drives the corresponding rotating wheel 30 and the transmission shaft 28 to rotate. The gear 29 on the outer wall of the transmission shaft 28 rotates accordingly. Through the meshing transmission between the gears 29, the gear 29 on the other side also rotates synchronously, so that the two rotating wheels 30 rotate at the same time. Under the transmission action of the synchronous belt 32, the rotating wheel 21 starts to rotate. Then, through the connection of the rotating shaft 20, the adapter plate 12 drives the storage cylinder 19 to rotate at high speed, quickly drying the detection liquid on the surface of the stainless steel workpiece.

[0034] After debugging, the number of rotation cycles of motor 22 was determined, and it was controlled in conjunction with the controller in the device, thus ensuring the path distance of displacement block 24 each time it moves.

[0035] After the spin-drying is completed, the hydraulic rod 16 is activated for the third time, driving the top plate 17 to move upward again, and the cover plate 11 rises accordingly. At the same time, the exhaust fan 7 and the air purifier 3 start synchronously. After the exhaust fan 7 starts, its input end quickly generates negative pressure. Under the action of the airflow channel composed of the guide pipe 8, the cavity box 9, and the bend pipe 10, the negative pressure is evenly distributed on the upper part of the inner wall of the soaking tank 2, drawing in the air in the soaking tank 2 along with the pungent odor emitted by the test liquid. The gas passes through the connecting pipe 6, the extension pipe 5, and the sealing cover 4 in sequence, and is finally guided to the air purifier 3. The air purifier 3 is filled with a high-efficiency adsorption material, which can deeply filter the inhaled gas, fully adsorb the harmful components and odors in it, and finally discharge a fresh and odorless airflow, creating a comfortable environment for the staff and avoiding discomfort or potential harm to the human body caused by the odor of the test liquid.

[0036] The working principle of this utility model is as follows: First, the hydraulic rod 16 is activated, causing its driving end to push the top plate 17 upward, simultaneously moving the cover plates 11 on both sides. The guide rods 14 connected to the opposite ends of the cover plates 11 slide within the limiting block 13. After the cover plates 11 move to a certain height, the driving end of the hydraulic rod 16 stops rising. Then, a certain amount of acidic and alkaline detection solutions are poured into the two immersion tanks 2 respectively, and identical stainless steel workpieces are placed in the two storage cylinders 19. Subsequently, the driving end of the hydraulic rod 16 is retracted, and the top plate 17 resets the cover plates 11 on both sides. Then, the storage cylinders 19 connected to the lower side of the cover plates 11 are immersed in the detection solution, which is then filtered through the mesh. 25 and 26, the test liquid will fully contact the stainless steel workpiece and corrode it within the specified immersion time to test the corrosion resistance of the stainless steel. After the test time is reached, the two motors 22 are started synchronously, causing the drive end of motor 22 to rotate the threaded rod 23, causing the displacement block 24 to slide upward in the slide frame 18 and move the placement cylinder 19. When the top of the placement cylinder 19 is in contact with the bottom of the adapter plate 12, motor 22 stops driving, and the stainless steel workpiece is removed from the test liquid. Then, motor 31 is started, causing its drive end to drive the corresponding rotating wheel 30 and the transmission shaft 28 to rotate, and on this side As the drive shaft 28 rotates, it drives the gear 29 on its outer wall to rotate. Then, under the meshing transmission, the other gear 29 rotates synchronously, causing the two rotating wheels 30 to rotate simultaneously. Under the transmission of the synchronous belt 32, the two rotating wheels 21 rotate. Then, through the connection of the rotating shaft 20, the adapter plate 12 rotates, further driving the storage cylinder 19 to rotate. This spins off the detection liquid on the surface of the stainless steel workpiece inside the storage cylinder 19, preventing the detection liquid on the surface of the stainless steel workpiece from continuing to react with the stainless steel after the workpiece is directly removed, thus avoiding affecting the detection results. After the spin-drying is completed, the hydraulic rod 16 is activated again, causing its drive end to push... As the top plate 17 moves upward, the cover plate 11 moves upward along with the top plate 17, simultaneously activating the exhaust fan 7 and the air purifier 3. When the exhaust fan 7 is activated, a negative pressure is generated at its input end. As the combination of the guide pipe 8, cavity box 9, and bend pipe 10 extends, the negative pressure effect is distributed on the upper part of the inner wall of the soaking tank 2, drawing in the surrounding air. At this time, the odor of the test liquid in the soaking tank 2 is drawn into the exhaust fan 7 with the airflow, and discharged to the air purifier 3 through the connecting pipe 6, extension pipe 5, and sealing cover 4. After being filtered by the adsorption material in the air purifier 3, the odorless airflow is discharged, thus preventing the pungent odor in the test liquid from spreading into the environment and causing discomfort to the staff.
