Description

Technical Field

[0001] The utility model relates to the field of precious metal recovery, in particular to a solid-liquid separation device for precious metal recovery. Background Art

[0002] Precious metals refer to eight metal elements, including gold, silver and platinum group metals (ruthenium, rhodium, palladium, osmium, iridium and platinum). They have unique physical and chemical properties and are used as electronic, electrical, photosensitive and catalyst materials. They are widely used in petrochemicals, aerospace, electronic appliances, communications equipment, computers, automobiles and other fields. They play an important and irreplaceable role in modern science and technology and industry. Precious metal waste is dissolved and filtered, and then a reducing agent is added to the dissolving solution to precipitate precious metal substitutes. Finally, the solid-liquid separation device for precious metal recovery is used to separate the solid and liquid in the dissolving solution.

[0003] For example, Chinese patent: Publication No. CN217367353U discloses a solid-liquid separation device for precious metal recovery, comprising a box body, a top cover and a filter screen plate. The top of the box body is provided with a top cover, the top of the top cover is provided with a stirring mechanism, a filter screen plate is provided inside the box body, the top of the filter screen plate is provided with an auxiliary structure, disassembly and assembly structures are provided on both sides of the bottom of the filter screen plate, the stirring mechanism comprises a servo motor, a rotating rod and stirring blades, the servo motor is provided at the top of the top cover, the bottom of the top cover is provided with a rotating rod, and the bottom of the rotating rod is provided with stirring blades.

[0004] Although the filter screen plate can be conveniently disassembled and assembled by engaging or separating the limit groove and the limit block, the convenient disassembly and assembly of the filter screen plate not only makes it convenient for the staff to take out the filter screen plate and collect the solid matter on the top thereof, but also facilitates the replacement of the filter screen plate. However, the device needs to take the filter screen plate out of the box for operation every time the filter screen plate is cleaned and the solid matter is collected, which wastes time and has low work efficiency. At the same time, when the solution is poured into the box for filtration, there is a lack of equipment to protect the filter screen plate. When the impact force of the solution poured in is too large, the filter screen plate is easily damaged, thereby increasing the separation cost.

[0005] To this end, we proposed a solid-liquid separation device for precious metal recovery. Utility Model Content
