Description

Technical Field

[0001] This utility model relates to the field of corrosion testing technology, specifically to a high-precision, intelligent, multi-functional periodic immersion corrosion chamber. Background Technology

[0002] Cyclic immersion corrosion testing is a commonly used accelerated environmental corrosion testing method both domestically and internationally. It primarily involves conducting cyclic immersion corrosion experiments on metallic materials under controlled environmental parameters in a laboratory setting, including corrosive solution concentration, pH, ambient humidity, pollutant gas concentration, and temperature, with and without applied stress. This method is suitable for evaluating the corrosion resistance of various metallic materials and is characterized by its ease of operation, short cycle time, and reliable results. It is widely used in the performance evaluation and research and development of various new corrosion-resistant metallic materials. Furthermore, depending on changes in the chemical composition of the experimental solution and other environmental parameters, it can also be used to study the corrosion resistance of metallic coatings and organic coatings.

[0003] A search revealed a utility model patent with publication number CN111781131B, which discloses a high-precision, intelligent, multi-functional periodic immersion corrosion chamber, belonging to the field of environmental corrosion testing technology. The device includes a chamber body, a lifting system, an infrared heating system, a water bath constant temperature system, a motor lifting system, a corrosion liquid tank, an intelligent water injection system, various detection systems, and an electrical control panel. The corrosion liquid tank is installed inside the chamber, and its side is placed within the water bath constant temperature system.

[0004] The aforementioned patent, by employing a corrosion liquid level concentration controller, a chamber humidity controller, and a gas concentration controller to precisely control parameters such as corrosion liquid concentration, chamber humidity, and gas concentration within the chamber during the experiment, can effectively simulate accelerated corrosion experiments, mimicking the corrosive effects of different environmental factors on the samples. This reduces experimental errors caused by large fluctuations in environmental parameters and meets the indicators specified in relevant standards. In corrosion tests, the test sample is typically made into a sheet and fixed on a lifting frame. A motor drives the lifting frame to bring the test sample into contact with the solution in the corrosion tank, thus achieving the testing purpose. However, when sampling multiple samples to witness the experimental results, it is impossible to fully observe individual samples. The lifting frame needs to be moved by a motor to remove all samples, which is impractical and affects the contact time between other samples and the solution, as well as the experimental results.

[0005] Therefore, it is necessary to invent a high-precision, intelligent, multi-functional periodic immersion corrosion chamber to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide a high-precision, intelligent, multi-functional periodic immersion corrosion chamber. An electric push rod moves a movable block while a sliding block slides along a track within a sliding groove, allowing the top two push rods to alternately rise and fall. These push rods then eject the corresponding sample from the top of the solution chamber. Through the coordinated use of a servo motor, a screw, a guide rod, and a moving block, individual sample ejection from any position is achieved. This facilitates observation of the corrosion resistance test results and improves usability. It addresses the problem in existing technologies where individual sample observation is insufficient, requiring a motor-driven lifting frame to remove all samples, resulting in low practicality and impacting the contact time between other samples and the solution, as well as the overall experimental effect.

Detailed Implementation

[0024] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0025] This utility model provides, for example Figure 1-6 The high-precision intelligent multifunctional periodic immersion corrosion chamber shown includes a working chamber 1, a solution tank 12, and an alternating lifting mechanism 17.

The connecting rods 7 are slidably connected to the partition 3. A lifting plate 8 is fixedly connected to the bottom of the connecting rods 7. Two sets of hooks 9 are symmetrically fixed to the bottom of the lifting plate 8. Multiple hooks 9 are provided, and steel wire ropes 10 are movably sleeved on each hook 9. Samples 11 are installed at the ends of the steel wire ropes 10. The solution tank 12 is fixedly installed on the bottom wall of the working chamber 1. A servo motor 17 is installed on the side of the working chamber 1. The output shaft of servo motor 13 is fixedly connected to screw 14 via a coupling. Screw 14 is connected to the working box 1 for rotational limitation. A guide rod 15 is fixedly connected to the inner wall of the working box 1. A moving block 16 is threaded onto the outside of screw 14. The moving block 16 is slidably sleeved on the outside of the guide rod 15. An alternating lifting mechanism 17 is detachably connected to the top of the moving block 16. The lifting block 6 can move linearly up and down along screw 15 by using the limiting property of connecting rod 7 within partition 3. This is used to adjust the height of lifting plate 8 and sample 11, as well as the contact range with the solution in solution tank 12. Sample 11 is directly hung on hook 9 via wire rope 10 for easy subsequent removal and unloading. During the rotation of screw 14 driven by servo motor 13, the guiding property of guide rod 15 can limit the linear movement of moving block 16 along screw 14. The position of alternating lifting mechanism 17 and the bottom of sample 11 can be adjusted.

[0026] The alternating lifting mechanism 17 includes a support frame 18, which is detachably connected to the movable block 16 by screws.

A guide block 21 is fixedly connected to the bottom of the movable block 20. A guide groove 22 matching the guide block 21 is opened inside the support frame 18. When the electric push rod 19 pushes the movable block 20 to move back and forth, the sliding block 26 connected to the first and second lifting rods 24 and 25 will slide along the trajectory in the sliding groove 23, so that the first and second lifting rods 24 and 25 move up and down alternately, which can alternately lift the sample 11 at the top, so as to achieve individual sampling and inspection.

[0027] The movable block 20 has a sliding groove 23 inside. The movable block 20 has a first ejector rod 24 and a second ejector rod 25 on its side. The side of the first ejector rod 24 and the second ejector rod 25 near the movable block 20 is fixedly connected to a sliding block 26 that matches the sliding groove 23. The outside of the first ejector rod 24 and the second ejector rod 25 are slidably sleeved with a limit sleeve 27. The limit sleeve 27 is fixedly connected to the support frame 18.

The gas concentration controller 33 specifically controls the concentrations of SO2 and NOx gases. The display 35 is used to display parameter information in real time during the experiment. In practical applications, the corrosion tank liquid level control system consists of the liquid level controller 32 and liquid level probes 50, 51, 52, and... The electrically controlled valve 48 is connected to the liquid level probe 50 and the liquid level probe 51 are spaced 1-5 cm apart. When the liquid level is lower than the height of the liquid level probe 51, the liquid level controller 32 opens the electrically controlled valve 48 to inject water. When the liquid level reaches the height of the liquid level probe 50, the electrically controlled valve 48 closes to stop the water injection. The gas concentration control system is connected to the gas concentration controller 33, the gas concentration sensor 42, the gas concentration sensor 43 and the corresponding vent pipe electric valve. When the gas concentration is low, the electric valve is opened to inject gas. When the gas concentration reaches the required level, the electric valve is closed to stop the gas injection.

[0029] A humidifier 37 is installed between the bottom of partition 1 2 and one side of the inner wall of the work chamber 1. A water inlet pipe 38 is fixedly connected to the side of the humidifier 37, extending to the outside of the work chamber 1. A conduit 39 is fixedly connected to the bottom of the humidifier 37, extending to the bottom of partition 2 3. A temperature sensor 40 is installed on one side of the conduit 39, and the temperature sensor 40 is fixedly snapped into partition 2 3. A humidity sensor 41, a gas concentration sensor 42, and a gas concentration sensor 43 are fixedly snapped into the inside of partition 2 3. An exhaust fan 44 is fixedly snapped into the rear side of the inner wall of the work chamber 1. Infrared heating lamps 45 are installed on both sides of the inner wall of the work chamber 1.

The chamber temperature controller system is connected to the ambient temperature controller 29, temperature sensor 40, and infrared heating lamp 45 to realize real-time temperature control inside the work chamber 1. The chamber humidity control system is connected to the humidity controller 30, humidity sensor 41, humidifier 37, and exhaust fan 44 to control the humidity inside the work chamber 1 in real time. When the humidity is low, the humidifier 37 is automatically turned on to humidify. When the humidity meets the requirements, the humidifier 37 is turned off. When the humidity is high, the exhaust fan 44 is automatically turned on.

[0030] A water injection pipe 47 is fixedly connected to one side of the working box 1. An electrically controlled valve 48 is installed between the water injection pipe 47 and the working box 1. A fixed base 49 is installed on the other side of the working box 1. Liquid level probe 50, liquid level probe 51 and liquid level probe 52 are connected to the side of the fixed base 49. An electric heating tube 53 and a temperature sensor 54 are installed at the bottom of the working box 1. Liquid level probe 50 is placed at the highest liquid level, liquid level probe 51 is placed 1-3 cm below the highest liquid level, and liquid level probe 52 is placed at the bottom of the solution.

[0031] The working principle of this practical application is as follows:

[0032] When the power switch 34 is turned on, the lifting plate 8 can be adjusted to move up and down as the servo motor 4 drives the screw 5 to rotate. The sample 11 is hung on the hook 9 and lowered into the solution tank 12 to contact the solution for corrosion resistance testing. When it is necessary to check the corrosion of one of the samples 11, the alternating lifting mechanism 17 is sent to the bottom of the sample 11 by the servo motor 13, and the moving block 20 is pushed by the electric push rod 19, so that the sliding block 26 slides in the sliding groove 23. The top material rod 24 with the upward action lifts the sample 11, so that the staff can check the sample 11 through the observation window 46.

[0033] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
