Abstract
Description
Technical Field
[0001] This utility model relates to the field of reaction vessel technology, specifically to a high-efficiency dissolution reaction vessel for precious metal extraction. Background Technology
[0002] In the precious metal extraction industry, reaction vessels are one of the core pieces of equipment, primarily used to process raw materials such as ores, electronic waste, or catalysts containing precious metals. These reaction vessels separate precious metals from a solid matrix through chemical dissolution processes (such as using aqua regia, cyanide, or other solvents). Typical reaction vessel designs include a corrosion-resistant vessel body, a heating system (such as built-in heating elements) to accelerate the reaction rate, a stirring device to ensure uniform mixing of the solution, and integrated filtration components (such as filter cartridges with perforations) to separate undissolved solid residues. The entire dissolution process must be carried out in a closed, controlled environment to ensure reaction efficiency and prevent the escape of harmful substances, ultimately achieving the efficient recovery of precious metals such as gold, silver, and platinum. This equipment is widely used in mineral refining, electronic waste recycling, and refining plants, and is crucial for improving resource utilization and economic efficiency.
[0003] Existing reaction vessels still have significant drawbacks. Temperature control mechanisms are often not precise enough, filter tank structures are poorly designed, and replacement and cleaning processes are cumbersome, requiring the disassembly of multiple connecting parts, which prolongs downtime and increases maintenance costs.
