Description

Technical Field

[0001] The invention relates to the technical field of material science and corrosion control, in particular to a time-controlled electrification corrosion device. Background Art

[0002] In the field of materials science and engineering, electrochemical corrosion testing of metal materials is a crucial research method. Through electrocorrosion experiments, researchers can evaluate the durability, life prediction and corrosion behavior of materials in specific corrosive environments. These studies are particularly important in industrial fields such as power facilities, bridges, buildings, ships and petrochemicals, because metal materials are exposed to corrosive media for a long time and are easily corroded, resulting in degradation of material performance and even endangering the safety of equipment and facilities. Therefore, electrochemical corrosion testing plays an important role in material development, quality control and optimization of anti-corrosion technology.

[0003] At present, traditional electrical corrosion experiments often rely on manual control of corrosion time. The experimenter applies current by directly connecting a constant current power supply and manually controls the power-on time using a timer. However, this method has many shortcomings. Since manual control is greatly affected by human factors, the accuracy of the power-on time is difficult to guarantee, resulting in fluctuations in experimental conditions and errors in results. In addition, the manual operation method requires the operator to participate in the entire process, which increases the workload of the experiment. There is also a risk of operating errors, making it difficult to achieve automation and standardization of the experimental process. Therefore, how to effectively control the power-on time of the corrosion process and improve the accuracy and repeatability of the experiment is a problem that needs to be solved in the prior art. Summary of the invention

[0004] The purpose of the embodiments of the present invention is to provide a timing controllable electric corrosion device, aiming to solve the technical problems mentioned in the background technology.

[0005] To achieve the above object, the present invention provides the following technical solutions:

This design greatly improves the accuracy and repeatability of the corrosion experiment, avoids the time error caused by manual operation, and ensures the high consistency of the experimental conditions each time.

[0019] In traditional corrosion experiments, manual control of power-on time is often interfered by human factors, resulting in fluctuations and errors in experimental results.

[0024] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0025] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0026] like Figure 1-Figure 2 As shown, an embodiment of the present invention provides a time-controllable electric corrosion device, which includes a corrosion box body 1 and a constant current power supply 13. The corrosion box body 1 is internally movably connected with a plurality of racks 2.

[0027] An external rack 3 is provided on the side of the corrosion box body 1 , and a timing control component 4 is placed inside the external rack 3 .

[0028] The timing control assembly 4 includes a mounting shell, and a control panel 8 and a display screen 7 are mounted on the surface of the mounting shell. A battery 10, a processing system 11 and a relay 12 are arranged inside the timing control assembly 4. A wiring hole 9 is opened on the surface of the mounting shell.

[0029] The positive electrode of the constant current power supply 13 is electrically connected to the relay 12 through a wire, and the negative electrode of the constant current power supply 13 is connected to the carbon rod through a wire.

[0030] The battery 10 is electrically connected to the display screen 7 and the control panel 8 , and the processing system 11 is electrically connected to the control panel 8 , the display screen 7 and the relay 12 .

[0031] In one embodiment of the present invention, the corrosion box body 1 is one of the core structures of the entire device, which is used to contain the corrosion solution and carry the sample to be corroded. The corrosion box body 1 is internally movably connected with a plurality of racks 2, which can be used to place samples of different sizes and immerse them in the corrosion solution to perform corrosion experiments. The movable connection design of the rack allows its position to be adjusted to meet different experimental requirements and improve the flexibility and practicality of the experiment.

[0032] An external rack 3 is provided on the side of the corrosion box body 1, and a timing control component 4 is placed inside the external rack. This design makes the timing control component relatively independent from the corrosion box body, which is convenient for operating the timing control component and avoids the direct impact of the corrosion solution on the electronic components. The timing control component 4 includes a mounting shell, and a control panel 8 and a display screen 7 are mounted on the surface of the mounting shell. The control panel 8 is used to set the power-on time during the corrosion process, and the display screen 7 is used to display the current set time and operating status. The surface of the mounting shell is also provided with a wiring hole 9 to facilitate the connection of the wires and the layout of the circuit.

[0033] The timing control component 4 is internally provided with a battery 10, a processing system 11 and a relay 12. The battery 10 is used to power various parts of the timing control component to ensure that the control panel 8, the display screen 7 and the processing system 11 can work normally. The processing system 11 is the core part of the timing control component. It receives the time setting input by the user on the control panel and controls the relay 12 according to the set time, thereby realizing the on-off control of the circuit. The relay 12 is used to control the output of the constant current power supply to ensure that the corrosion experiment is carried out within the predetermined time. The relay is also electrically connected to the sample to be corroded through a wire to ensure that when the power is turned on, the current can pass through the sample smoothly for corrosion.

[0034] The constant current power supply 13 is a core component that provides a stable current. The positive electrode of the constant current power supply 13 is electrically connected to the relay 12 through a wire. The function of the relay is to open or disconnect the circuit according to the set time to control whether the current flows to the sample to be corroded. The negative electrode of the constant current power supply 13 is connected to the carbon rod through a wire. The carbon rod is used as a cathode to form a current loop in the corrosion electrolysis process.

[0035] The battery 10 is electrically connected to the display screen 7 and the control panel 8 to ensure independent power supply for the control and display functions. The processing system 11 is electrically connected to the control panel 8, the display screen 7 and the relay 12. The processing system receives input through the control panel and displays the set state on the display screen, and controls the switch of the relay to achieve current control of the constant current power supply.

[0036] The operator can choose to prepare the required amount of solution and add it directly into the corrosion box body 1, or prepare the solution in the corrosion box body 1. This design provides flexibility and facilitates the operator to adjust the concentration and volume of the solution according to experimental requirements.

[0037] The working process of the whole device is as follows: First, place the sample to be corroded on the rack 2 in the corrosion box body 1. The corrosion time is set through the control panel 8, and the processing system 11 controls the on and off state of the relay 12 according to the set time, thereby controlling the power supply process of the constant current power supply 13 to the sample. After the set time is reached, the relay disconnects the circuit and stops supplying power to the sample, thereby completing the corrosion experiment. In this way, the corrosion time can be accurately controlled to ensure the reliability and repeatability of the experimental results.

[0038] In summary, the present invention realizes precise timing control of corrosion experiments by setting a timing control component 4, ensuring the automation and consistency of experimental operations. The timing control component 4 includes a processing system 11, a control panel 8, a display screen 7 and a relay 12. The user can set a specific power-on time through the control panel 8, and the processing system 11 accurately controls the on and off state of the relay 12 according to the set time, thereby realizing the automatic on and off of the constant current power supply 13. This design greatly improves the accuracy and repeatability of corrosion experiments, avoids time errors caused by manual operations, and ensures a high degree of consistency in each experimental condition.

[0039] In traditional corrosion experiments, manual control of the power-on time is often interfered by human factors, resulting in fluctuations and errors in the experimental results. The present invention overcomes the defects of manual operation by adopting the timing control component 4, eliminates the uncertainty in the experiment, and standardizes the entire process. The use of the constant current power supply 13 and the timing control component 4 ensures the stability of the current and the precise control of time during the corrosion process, thereby improving the controllability of the corrosion rate and the reliability of the experimental data. The use of the relay 12 allows the device to automatically open or close the circuit within the set time, without the need for manual intervention by the operator, thereby reducing the workload and improving the convenience and safety of the experiment.

[0040] In summary, the present invention significantly improves the repeatability, accuracy and automation level of corrosion experiments through the timing control function, effectively overcomes the shortcomings of traditional manually controlled corrosion experiments, is suitable for various experimental scenarios for precise control of the corrosion process, and has broad application value and good development prospects.

[0041] In this embodiment, the number of racks 2 is set to two, and the two racks 2 are independent of each other. The top surface of the rack 2 is provided with an anti-skid pad, and the bottom surface of the rack 2 is provided with an anti-skid protrusion. By providing an anti-skid pad on the top surface of the rack 2, it is ensured that the sample will not slide due to external force or liquid flow during the experiment, thereby ensuring the stability of the sample, thereby improving the uniformity of the corrosion process and the accuracy of the experimental results.

[0042] The anti-skid protrusions at the bottom of the rack 2 further enhance the friction between the rack and the corrosion box, ensuring that the rack 2 is not easy to move during the experiment, effectively improving the consistency and reliability of the experiment. The two racks can be flexibly adjusted to accommodate samples of different sizes and quantities, increasing the diversity and efficiency of the experiment.

[0043] In this embodiment, a guide slot 5 is provided inside the corrosion box body 1, a positioning slider 6 is provided on the surface of the rack 2, and the rack 2 is slidably connected to the inside of the corrosion box body 1 through the cooperation of the positioning slider 6 and the guide slot 5.

[0044] This design allows the rack 2 to flexibly adjust its position according to experimental requirements and adapt to samples of different specifications and sizes. The sliding connection between the guide chute 5 and the adjustment slider 6 ensures that the rack 2 remains stable during the corrosion process, avoiding position displacement caused by vibration or external force, thereby ensuring full contact between the sample and the corrosion solution and improving the uniformity and repeatability of the corrosion experiment. At the same time, the adjustable sliding connection makes the experimental operation more convenient, facilitating the operator to quickly change or adjust the sample position, and improving the experimental efficiency and flexibility.

[0045] In addition, the material of the rack 2 and the positioning slider 6 is polytetrafluoroethylene, polypropylene or anodized aluminum alloy. These materials have good corrosion resistance and mechanical strength, can effectively resist the influence of corrosive solutions, and ensure the stability of the structure during the experiment and the reliability of long-term use. Polytetrafluoroethylene and polypropylene have excellent chemical inertness, while anodized aluminum alloy provides higher strength and wear resistance, which is suitable for different experimental requirements.

[0046] In this embodiment, a flexible support pad is provided inside the external rack 3, and the mounting shell is placed on the flexible support pad. Providing a flexible support pad inside the external rack 3 and placing the mounting shell on the flexible support pad can effectively reduce the impact of vibration and impact on the timing control component, protect the internal electronic components, and extend the service life of the device. At the same time, the flexible support pad can buffer the external force on the external rack during operation, avoid wear caused by direct contact between the mounting shell and the external rack, and improve the overall reliability and stability of the device.

[0047] In this embodiment, the surfaces of the external bracket 3 and the corrosion box body 1 are both provided with fixing threaded holes with the same inner diameter, and the inside of the fixing threaded holes are engaged with fixing bolts. The external bracket 3 is detachably connected to the corrosion box body 1 through the cooperation of the fixing bolts and the fixing threaded holes.

[0048] The advantage of this design is that the external bracket can be easily disassembled and reinstalled, which is convenient for cleaning and maintenance of the equipment. The detachable connection design enhances the flexibility of the equipment, which can not only ensure the stability of the external bracket installation, but also make the cleaning after the experiment more convenient, thereby extending the service life of the equipment and improving the overall efficiency of the experimental operation.

[0049] In this embodiment, volume scale lines are provided on the inner wall of the corrosion box body 1. This facilitates the operator to accurately control the volume of the corrosion solution added, thereby improving the accuracy and repeatability of the experiment. This design allows the amount of solution to remain consistent in each experiment, reduces the experimental error caused by the difference in solution volume, thereby ensuring the reliability of the experimental data and facilitating more accurate experimental parameter adjustment and result analysis.

[0050] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
