[0002] Silver has excellent ductility, and its electrical conductivity and thermal conductivity are the best among metals. As a precious metal, it has high value. In the existing technology, there are generally two methods for preparing silver: chemical method and electrolytic method. High-purity silver can be extracted through silver electrolytic purification and refining equipment.

[0003] When the existing silver electrolytic purification and refining device is in use, silver powder will adhere to the cathode plate. When removing the silver powder, the staff needs to manually scrape the silver powder off, which makes it difficult to output and collect the purified silver powder. The cathode plate needs to be processed for a long time to remove the powder, and the electrolytic cell cannot be put into operation again quickly, which affects the electrolysis efficiency of the electrolytic cell. Therefore, a new silver recycling electrolytic purification and refining device is urgently needed to solve the above problems. Utility Model Content

The cathode plate 7 continues to be lifted so that it passes between the scrapers 10. The spacing between the scrapers 10 is adapted to the width of the cathode plate 7. The scraper 10 scrapes the silver powder attached to the surface of the cathode plate 7 and scrapes it into the guide groove 11. The bottom surface of the guide groove 11 is an inclined surface.
