[0016] A high-temperature electrochemical testing system, such as Figure 1 As shown, the system includes a crucible 8, which is mounted on a crucible fixing base 6. A lower support rod 3 is mounted on the bottom of the crucible fixing base 6. The lower support rod 3 is mounted on the main unit base 2. A lower base plate 1 is mounted on the bottom of the main unit base 2. A rotating positioning frame 4 is fitted at the connection between the lower support rod 3 and the crucible fixing base 6. The rotating positioning frame 4 is fixedly connected to the fixing unit of the CT turntable (not shown in the figure). When the rotating unit of the CT turntable rotates, it drives the main unit base 2, the lower support rod 3, the electrolytic sample 7, the crucible 8, and the electrode assembly 10 to rotate together. The rotor of the slip ring 11 is connected to the rotating mechanism, and the stator is connected to the fixing mechanism, thereby achieving infinite rotation.
[0017] A crucible protective cover 9 is installed on the crucible 8, and the crucible protective cover 9 is fitted on the top of the crucible 8. An upper cover plate 12 is installed on the top of the crucible protective cover 9, and an electrode wire plug 13 is provided on the upper cover plate 12. An electric slip ring 11 is installed inside the upper cover plate 12. An electrolytic sample 7 is installed inside the crucible 8, and an electrode assembly 10 is installed on the top of the crucible 8. The two are threaded together to ensure that there is no shaking during rotation, so that the CT scan image is clearer. The bottom of the electrode assembly 10 is connected to the electrolytic sample 7, and the top of the electrode assembly 10 is connected to the electric slip ring 11.
[0018] like Figure 2 and Figure 3 As shown, it also includes a high-temperature vacuum furnace 22. The high-temperature vacuum furnace 22 is mounted on the crucible 8. Specifically, the length, width and height of the high-temperature vacuum furnace are all less than 150mm, and it is used in CT fields, X-ray fields and diffraction fields.
[0019] The high-temperature vacuum furnace 22 is located below the crucible protective cover 9. The high-temperature vacuum furnace 22 includes a high-temperature furnace body 18. A front door body 111 and a rear door body 19 are respectively installed at both ends of the high-temperature furnace body 18. A front door glass plate 131 and a front door pressure plate 121 are installed on the front door body 111. The front door pressure plate 121 is located outside the front door glass plate 131. A rear door glass plate 15 and a rear door pressure plate 17 are installed on the rear door body 19. The rear door pressure plate 17 is located outside the rear door glass plate 15.
[0020] A heating motor base 21 is installed on one side of the high-temperature vacuum furnace 22. A heating wire 14 is installed inside the high-temperature furnace body 18. The heating wire 14 is made of electrothermal alloy wire and is arranged on the outer ring of the crucible 8. When X-rays pass through, they are transmitted evenly without causing ghosting and affecting the image of the sample. The heating wire 14 is used as the internal heating element of the high-temperature furnace body 18. In actual use, under a voltage of about 15V and a current of about 100A, its temperature can reach 1000℃, which can ensure that the equipment works stably under the 36V human safety voltage.
[0021] In addition, the heating wire 14 is also connected to a controller, which controls the voltage and current output of the heating wire 14 to maintain a constant temperature inside the high-temperature vacuum furnace 22.
[0022] Insulation layers 16 are installed at the top and bottom of the inner side of the high-temperature furnace body 18. The insulation layers 16 are located at the top and around the top of the heating wire 14. Specifically, the insulation layer is formed by multiple layers of high-temperature resistant heat insulation boards to form a heat insulation screen. In actual operation, the high-temperature furnace body 18 is evacuated or filled with inert protective gas to make the insulation effect of the insulation layer 16 better.
[0023] Two water-cooling connectors 20 are installed at the top of the high-temperature furnace body 18. The two water-cooling connectors 20 are located on both sides of the crucible 8, such as... Figure 4 As shown, a water circulation system 23 is installed on the outer ring of the crucible fixing seat 6. The water circulation system 23 is located between the high temperature furnace limiting plate 5 and the high temperature furnace body 18. The temperature of the system is ensured by the water cooling joint 20 and the water circulation system 23, thereby better protecting the high temperature furnace body. The water circulation system 23 added below the high temperature furnace body 18 can also ensure that the temperature of the high temperature furnace body 18 will not be conducted downward to the CT turntable.
[0024] The interior of the heat preservation furnace body 18 is treated with multiple layers of heat insulation. At the same time, multiple cooling modules are designed on the high-temperature furnace body 18, so that the heat transferred to the furnace body is close to the water temperature of 30°C. This ensures that the X-ray source of industrial CT can approach the high-temperature vacuum furnace and further approach the electrolytic sample, thereby enabling the capture of high-resolution images. In practice, high-resolution images within 3μm can be captured.
[0025] An opening is provided on the rotating positioning frame 4, and a high-temperature furnace limiting plate 5 is also fitted at the connection between the lower support rod 3 and the crucible fixing seat 6. The high-temperature furnace limiting plate 5 is located inside the opening, and the diameter of the high-temperature furnace limiting plate 5 is smaller than the diameter of the side opening.
[0026] After the high-temperature vacuum furnace 22 is connected through the high-temperature furnace limiting plate 5, the high-temperature vacuum furnace 22 floats in the opening on the rotating positioning frame 4. When the CT turntable, main unit base 2, lower support rod 3, electrolytic sample 7, crucible 8 and electrode assembly 10 rotate, the rotating positioning frame 4 restricts the rotation of the high-temperature vacuum furnace 22, so that the high-temperature vacuum furnace 22 does not move, and only the main unit base 2, lower support rod 3, electrolytic sample 7, crucible 8 and electrode assembly 10 rotate infinitely, ensuring that the X-rays of industrial CT can penetrate the electrolytic sample 7 and are not interfered with by the high-temperature vacuum furnace 22.
[0027] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
