Description

Technical Field

[0001] The present invention relates to the technical field of electrolytic cell experiments, in particular to a fully automatic multi-station H-type electrolytic cell experimental platform and an intelligent control system thereof. Background Art

[0002] Traditional electrolytic cell experimental setups present numerous limitations in scientific research and experiments involving electrolytic cells. The manual operation process is cumbersome, requiring significant time and effort from the experimenter, from electrode preparation and electrolyte addition to setting experimental parameters and product collection. Furthermore, manual operation can easily introduce errors, resulting in poor accuracy and reproducibility of experimental results.

[0003] At the same time, traditional electrolytic cells are typically single-station designs, making them difficult to accommodate for multiple parallel experiments or comparative experiments under different conditions, resulting in low experimental efficiency. Furthermore, electrolyte management is not intelligent enough, and operations such as electrolyte injection, sample retention, and waste liquid discharge and cleaning lack precise control, making automated processes impossible and unfavorable for large-scale, systematic experimental research. Summary of the Invention

[0007] Specifically, the H-type electrolytic cell includes two independently controlled electrolytic cell stations, each station adopts an H-type double-chamber structure, the anode and cathode areas are separated by a proton exchange membrane, a working electrode and a counter electrode are arranged in the anode chamber, and a reference electrode is arranged in the cathode chamber. A magnetic stirring motor is integrated under the cell body, and a stirring magnet is located in the cell, that is, the integrated magnetic stirring motor and the stirring magnet are separated by the cell body.

[0008] Specifically, the H-type electrolytic cell is provided with an electrolyte circulation system, which specifically includes an electrolyte addition peristaltic pump, a deionized water addition peristaltic pump, a sample retention peristaltic pump, a waste liquid pump and a multi-way solenoid valve, and realizes precise control of electrolyte injection, cleaning, sample retention and waste liquid discharge through multiple pipes;

[0009] Specifically, the electrolyte adding peristaltic pump and the deionized water adding peristaltic pump are arranged in parallel, and the liquid addition is controlled by independent electromagnetic valves respectively. The sample retention peristaltic pump is connected to the penicillin bottle, and automatically performs liquid product sampling when the reaction is terminated.

[0010] Specifically, the robotic arm and the mobile tool library are used in conjunction to realize electrode replacement. The electrode replacement consists of a six-axis robotic arm and a quick-change gripper. The entire process of "catalyst coating-curing-electrode loading" is performed by the robotic arm.

[0011] An intelligent control system for a fully automatic multi-station H-type electrolytic cell experimental platform includes the following steps:

[0012] S1. Load the experiment template through the human-machine interface or remote platform to automatically generate the device initialization instruction set;

[0013] S2: The robotic arm performs the entire process of conductive material loading, catalyst coating, and curing to prepare the test working electrode.

[0015] S4, the mass flow controller establishes the reaction atmosphere environment according to the preset program;

[0016] S5, the electrochemical workstation applies an excitation signal and starts multi-channel data acquisition synchronously;

[0017] S6. After the reaction is terminated, the standard cycle of product sample retention-electrode replacement-pipeline cleaning is automatically executed.

[0018] Specifically, in S1, the bottle type is selected to be opened or not opened, and then the experimental parameters are set as follows:

[0026] The specific cycle cleaning of pipeline cleaning is as follows:

[0027] The valve at the bottom of the H-type electrolytic cell is controlled to be in an open state, and then the drainage pump discharges the waste liquid in the H-type electrolytic cell into the waste liquid barrel;

[0028] When the waste liquid is discharged, the valve is closed again, and deionized water is injected into the H-type electrolytic cell through the deionized water peristaltic pump, and then the integrated magnetic stirring motor under the cell body is started to drive the stirring magnet to stir the deionized water to achieve the cleaning of the H-type electrolytic cell. The waste liquid after cleaning controls the valve at the bottom of the H-type electrolytic cell again to open it, and then the drainage pump discharges the waste liquid in the H-type electrolytic cell into the waste liquid barrel. The above steps are repeated to achieve the cleaning of the H-type electrolytic cell.

[0029] Beneficial effects

[0030] The present invention has the following beneficial effects:

[0031] This fully automated multi-station H-type electrolytic cell experimental platform utilizes an intelligent control system to automate the entire process, from experimental template loading, electrode preparation, electrolyte addition, reaction atmosphere control, data acquisition, product sampling, electrode replacement, and pipeline cleaning. This reduces manual intervention and human error, improves the accuracy and repeatability of experimental results, and saves significant manpower and time, enabling researchers to conduct their research more efficiently.

[0032] The H-type electrolytic cell contains two independently controlled workstations, each of which adopts an H-type dual-chamber structure, which can simultaneously conduct experiments under different conditions or different reaction systems, greatly improving experimental efficiency and meeting the needs of multiple groups of parallel experiments or comparative experiments. In addition, through the flexible setting of experimental parameters (such as catalyst drop volume, electrolyte addition amount, conductive material drying time, stirring speed, etc.), it can adapt to diverse experimental needs and enhance the versatility and applicability of the experimental platform.

[0033] The experimental platform integrates multiple functional modules such as a robotic arm, mobile tool library, bottle rack, conductive material rack, TIP head box rack, drying table, etc., integrating electrode preparation, experimental operation, product processing and other links on a single platform, realizing efficient utilization and centralized management of experimental resources.

[0034] The electrolyte circulation system is equipped with an electrolyte addition peristaltic pump, a deionized water addition peristaltic pump, a sample retention peristaltic pump, a waste liquid pump and a multi-way solenoid valve. It can achieve precise control of electrolyte injection, sample retention and waste liquid discharge, ensuring the consistency and stability of experimental conditions. Through multiple cycles of deionized water injection and discharge, the integrated magnetic stirring motor under the cell body is started to drive the stirring magnet to stir the deionized water, realizing cyclic cleaning of the cell body, providing convenience for subsequent experiments.

[0035] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS
