Description

Technical Field

[0001] This utility model relates to environmental protection technology and its equipment, specifically, to the anode structure in an electrolytic recovery device for gold plating waste containing gold cyanide. Background Technology

[0002] The method for electrolytically recovering gold from cyanide-containing gold plating wastewater targets the cyanide-containing gold plating wastewater generated in the gold plating section of the PCB production process. This wastewater contains a certain concentration of cyanide and the precious metal gold. Direct discharge into the environment can cause serious pollution. At the same time, this wastewater also has high recycling value.

[0003] Electrolysis is a common method for recovering gold from cyanide-containing gold plating waste liquid. However, due to the different concentrations and recovery efficiencies of cyanide-containing gold plating waste liquid, some applications require the use of anodes driven by high-frequency switching power supplies, such as ruthenium-iridium-titanium anodes, for high-frequency, high-density electrolysis; while other applications require the use of stainless steel anodes for low-current electrolysis.

[0004] Currently, different anode modules are typically configured, and the anodes are replaced to match the corresponding electrolysis requirements, which seriously wastes production resources. At the same time, replacing electrodes also affects electrolysis efficiency.

[0005] Therefore, it is necessary to provide an anode structure in an electrolytic recovery device for gold-plating waste containing gold cyanide to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide an anode structure for an electrolytic recovery device of gold-plating waste containing gold cyanide.

[0007] The technical solution is as follows: An anode structure in an electrolytic recycling device for gold-containing cyanide waste gold plating solution includes a rotating support part, on which an anode support plate is rotatably mounted. A stainless steel anode is mounted at one end of the anode support plate, and a ruthenium-iridium-titanium anode is mounted at the other end. A power fastening block A is mounted on the upper part corresponding to the stainless steel anode, and a power fastening block B is mounted on the upper part corresponding to the ruthenium-iridium-titanium anode. The rotating support unit is equipped with a power fastening connecting block A for use with the upper block A of the power fastening unit and a power fastening connecting block B for use with the upper block B of the power fastening unit. A rotating drive component is set up through the anode support plate corresponding to the stainless steel anode and the ruthenium-iridium-titanium anode. The extension / retraction of the rotating drive component drives the power fastening connecting block A and the upper block A of the power fastening unit to connect, and the upper block B of the power fastening unit and the power fastening connecting block B to connect, forming a rapid anode switching structure.

[0008] Furthermore, the extension / retraction of the rotation drive unit connects the upper block A of the power supply fastening part and the power supply fastening connecting block A, forming a low-current electrolytic treatment anode assembly structure.

[0009] Furthermore, the extension / retraction of the rotating drive component connects the power supply fastening block B and the upper block B of the power supply fastening part, forming a high-frequency, high-density electrolytic anode combination structure.

[0010] Furthermore, the anode support plate in the corresponding area of ​​the stainless steel anode and the ruthenium-iridium-titanium anode, which do not have a rotation drive component, is equipped with a rotation limit block.

[0011] Furthermore, the rotation drive includes a rotation cylinder, and an insulating pad is provided at the connection between the rotation cylinder and the anode support plate.

[0012] Furthermore, the rotating bearing part includes a base plate, a rotating bearing triangular plate is provided on the base plate, a rotating wheel is provided on the rotating bearing triangular plate, and an anode bearing plate connecting shaft is provided on the rotating wheel.

[0013] Furthermore, an insulating washer is provided at the connection between the anode support plate connecting shaft and the anode support plate.

[0014] Furthermore, both power fastening connecting block A and power fastening connecting block B include connecting pieces disposed on the flexible pad, and the anode connector also serves as a soft contact buffer.

[0015] Furthermore, on the anode support plate, tension springs are provided on both sides corresponding to the power fastening connecting block A and the power fastening connecting block B. One end of the tension spring is connected to the anode support plate and the other end is connected to the base plate.

[0016] Compared with existing technologies, this invention can quickly switch between low-current electrolytic anode combination structures and high-frequency, high-density electrolytic anode combination structures, effectively ensuring electrolysis efficiency while reducing the waste of production resources caused by multiple anode preparations.
