Description

TECHNICAL FIELD

[0001] The application relates to the technical field of precious metal recovery, in particular to a precious metal coating stripping and recovery equipment. BACKGROUND

[0002] At present, according to the requirements of energy saving and emission reduction, in order to solve the problem of recycling and utilization of renewable resources and promote the sustainable development of economy and society, the limited resources are integrated to form an industrial pattern integrating renewable resource recovery, processing and utilization and centralized treatment, so as to realize the service of the whole life cycle of products and improve the service of the whole product.

[0003] The precious metals mainly refer to gold, silver and eight kinds of metal elements such as platinum group metals (ruthenium, rhodium, palladium, osmium, iridium and platinum), most of which have beautiful colors and strong chemical stability and are not easy to react with other chemical substances under general conditions. Metal recovery refers to the useful substances separated from waste metals and processed into recycled products through physical or mechanical processing.

[0004] Titanium coating anodes are widely used in the fields of environmental protection, electroplating, electrochemical synthesis and electrocatalysis due to their high electrochemical performance and strong corrosion resistance, and the use amount is large and continuously increasing every year. The surface of the waste titanium coating anode has a certain precious metal coating, and the main precious metals are iridium and ruthenium. The main process of repairing the waste anode is to remove all the original coatings. Since the iridium and ruthenium on the surface have recycling value, it is very necessary to recycle and reuse the waste anode. The key to recycling is to strip the precious metal coating on the surface of the titanium anode with the least damage to the titanium substrate.

There are also grinding and polishing devices for grinding and recycling, but most of the grinding devices are not complete in collecting and recycling the materials ground, which is easy to cause dust exceeding the standard. The collection by the dust collector is not conducive to the subsequent recovery, and a part of the device can only polish the flat surface, which also damages the original curvature of the waste anode, and there is room for improvement.
