Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of hydrometallurgy zinc smelting, in particular to a pre-stripping knife structure. Background Art
[0002] Hydrometallurgy involves electrolysis to adsorb metallic zinc onto cathode plates, which are then stripped from the plates and melted into ingots. Currently, fully automatic zinc stripping machines are being successfully applied in the hydrometallurgy industry due to their high speed, high efficiency, and labor-saving advantages, replacing manual labor. Their use is gradually increasing in Chinese hydrometallurgical enterprises. Stripping is difficult due to the strong bond between the metallic zinc and the cathode plates, especially between the upper edge of the zinc sheet and the cathode plates. This tight bond can be caused by a variety of factors, including variations in electrolyte parameters leading to a high fluorine content in the electrolytic metal and wear and tear of the cathode plates due to long-term use. To facilitate the mechanical stripping process, a pre-stripping step is implemented before the stripping process to create a gap between the upper edge of the zinc sheet and the cathode plate. This gap is manually chiseled out from the upper edge of the zinc sheet. While this pre-stripping method achieves some success, it is labor-intensive and creates dense acid mist in the zinc electrolysis workshop, seriously affecting the health of workers who work long hours. Furthermore, since the cathode plate conductive rod is made of pure aluminum, it can bear less force and the cathode plate surface is not wear-resistant. When a chisel is used manually, there is a certain angle between the blade and the cathode plate surface. After multiple chiseling, the cathode plate will inevitably be damaged, which is not conducive to continuous electrolysis operation. Utility Model Content

Compared with the hydraulic system, it causes less damage to the cathode plate. At the same time, it avoids damage to the cathode plate caused by manual use of the chisel. The use of mechanical mechanism instead of manual operation ensures the health of workers. BRIEF DESCRIPTION OF THE DRAWINGS

The mounting base 15 is also equipped with a limit bracket 14, which presses against one side of the base plate 6 to adjust the retraction position of the opening and closing cylinder 1. The opening and closing, as well as the up and down reciprocating motion of the stripper assembly 13, are driven by the cylinder. This creates a gap between the cathode plate and the zinc sheet, providing sufficient cutting force to achieve a pre-cutting of the zinc sheet, while causing less damage to the cathode plate than a hydraulic system. Both the horizontal guide rail 3 and the vertical guide rail 10 utilize dual sliders, which allow the sliders to move more smoothly on the rails, ensuring more balanced force on components, extending the service life of the cylinder and components, and increasing structural reliability.
[0031] The stripping blade assembly includes a blade holder 131, the side of which is fixedly connected to the connecting plate 12. A blade 133 is provided at the bottom of the blade holder 131, and the blade edge of the blade 133 is tilted at a specific angle. Specifically, the connecting plate 12 and the blade holder 131 are fixedly connected by bolts, and the connecting plate 12 is provided with multiple rows of threaded holes, so that the stripping blade assembly can be adjusted up and down to accommodate cathode plates of different heights. A pad is provided between the blade 133 and the blade holder 131, and the pad 132 is connected to the blade holder 131 by bolts. The blade 133 is connected to the pad 132 by screws, making it easier to disassemble and replace the blade 133.
[0032] Working and usage process:
[0033] When the zinc sheet on the cathode plate needs to be pre-stripped, the opening and closing cylinder 1 is started. The floating joint of the opening and closing cylinder 1 is driven by the connecting earring 5 and the base plate 6, and the first slide 4 moves along the horizontal guide rail 3, thereby driving the upper and lower cylinders 7 and the stripping knife assembly 13 and other structures to move toward the zinc sheet, so that the blade 133 on the stripping knife assembly 13 is aligned with and abuts the upper edge of the zinc sheet and the cathode plate. At this time, the upper and lower cylinders 7 are started. The floating joint of the upper and lower cylinders 7 is driven by the connecting plate 12, and the second slide 9 moves along the vertical guide rail 10, thereby driving the blade 133 on the stripping knife assembly 13 to move in the vertical direction, shoveling a gap at the upper edge where the zinc sheet and the cathode plate are connected, completing the pre-stripping of the zinc sheet and the cathode plate.
