Compared to conventional silver electrolysis cells that use top-exhaust systems, resulting in large air volume, high air pressure, high energy consumption, and cluttered, disorganized space, our company’s silver electrolysis cell equipment employs a closed, bottom-exhaust system, as shown in the diagram. This eliminates smoke escape, improves energy efficiency, and creates a clean, aesthetically pleasing, and comfortable working environment. Our silver electrolysis equipment offers the following advantages:
Stable Production Process: The anode and cathode plates and conductive copper busbars are reinforced with stainless steel screws. The busbars are also reinforced with each other. The busbars and the tank body use bakelite boards to prevent leakage. The titanium plate connecting the cathode is reinforced with titanium-clad copper for the conductive parts, significantly enhancing conductivity and reducing resistance. This solves the problem of contact point overheating, reducing potential production hazards and decreasing anode mud production, thus lowering production costs.
Reduced Pollution and Better Working Environment: High-current-density silver electrolysis processes result in high electrolyte temperatures, causing the electrolyte to volatilize and produce nitrogen oxides and nitric acid mist, leading to poor working conditions in the workshop. Therefore, we designed a refrigeration system to cool the electrolyte, maintaining its temperature at around 40℃. At this temperature, both electrolysis efficiency and electrolyte evaporation are ensured. The top exhaust fan of the tank was changed to a side exhaust fan, and the top of the tank was sealed with a transparent glass cover. This allows for the removal of nitrogen oxide waste gas generated during electrolysis with only a small air volume, saving energy and significantly improving the working environment.
High-purity electrolytic silver powder: When using a high-current silver electrolysis process, the current density exceeds 750 A/m², which is 2-3 times that of conventional silver electrolysis processes. Electrolyzing the same mass of silver anode plates reduces the time by 60%. To avoid concentration polarization during high-current-density electrolysis, we designed a magnetic pump and changed the electrolyte circulation method, making the electrolyte flow parallel to the electrode plates. This magnetic pump + parallel flow electrolyte circulation design solves the concentration polarization problem and ensures the quality of the electrolytic silver powder.
Saves manpower and is easy to operate: An automatic silver powder scraping device is adopted. The bakelite scraper is connected to the scraper support, and the scraper is placed on both sides of the cathode plate. The scraper support is connected to a stainless steel frame, and driven by a crankshaft connecting rod and a motor, automatically scraping off the silver powder deposited on the cathode plate. A solid-liquid separation device is added to the lower end of the electrolytic cell. The electrolyte is discharged first through a bypass, and the wash water for the initial silver powder washing is also released through the bypass. The electrolytic silver powder is placed into a cleaning and drying integrated machine through a valve at the bottom of the electrolytic cell. After cleaning and drying, it is placed in a silver powder cart and directly sent to the ingot casting process. The remaining electrode residue after electrolysis is taken out of the anode bag and directly placed into the anode titanium frame for further electrolysis without remelting the anode.
