Description

Technical Field

[0001] This utility model relates to the field of electrochemical technology, specifically to a laboratory electrochemical device. Background Technology

[0002] Electrochemistry is the science that studies the interconversion between electrical energy and chemical reactions, primarily exploring the role and application of electric current in chemical reactions. Through electrochemical technology, various forms of energy conversion and material transformation can be achieved, such as electrical energy driving chemical reactions (e.g., electrolysis) and chemical reactions generating electrical energy (e.g., batteries). This technology is widely used in energy fields (e.g., batteries, fuel cells, energy storage systems), materials science (e.g., metal electroplating, surface treatment), environmental engineering (e.g., pollutant degradation, wastewater treatment), and industrial manufacturing (e.g., electrometallurgy, electrosynthesis), offering advantages such as high efficiency, strong controllability, and environmental friendliness.

[0003] In the specific operation of electrochemistry, electrons are usually transferred between the electrodes by applying an external voltage in an electrochemical cell composed of electrodes and electrolyte, thereby triggering a specific redox reaction. However, in most current devices, the installation of electrodes still relies on manual fixing in the reaction cell, which is not only cumbersome, time-consuming and labor-intensive, but also prone to affecting the repeatability of the experiment and the reaction efficiency due to unstable installation or poor contact.

[0004] Therefore, this invention provides a laboratory electrochemical apparatus to solve the above-mentioned problems. Utility Model Content

A spring 11 is fixedly connected to one side of the push plate 10 on the periphery of the telescopic rod 9. The telescopic rod 9 prevents the spring 11 from deforming, which would cause the push plate 10 to tilt. The spring 11 pushes and fixes the push plate 10, which can center and clamp the reaction bottle, effectively preventing it from shaking or shifting during operation. At the same time, it ensures that the working electrode 13, the counter electrode 14, and the reference electrode 17 are precisely aligned with the position of the reaction bottle, ensuring that each electrode can be smoothly and accurately inserted into the reaction solution, improving the stability and ease of operation of the experimental device, thereby ensuring the smooth progress of the test process and the accuracy of data acquisition.

Next, place the reference electrode 17 inside the second retaining ring 16 and connect and fix it to the fixing frame 15 with the second bolt to realize the installation and fixation of the reference electrode 17. Second, the telescopic rod 9 prevents the spring 11 from deforming and causing the push plate 10 to be tilted. The spring 11 pushes and fixes the push plate 10, which can center and clamp the reaction bottle. Finally, start the dual-axis motor 4 to drive the threaded rod 5 to rotate. Under the limiting guide of the limiting rod 8, the moving frame 6 can move left and right along its outer surface. Then start the cylinder 2 to push the mounting frame 3 downward, which can accurately control the position of the working electrode 13, the counter electrode 14 and the reference electrode 17.
