Technical Field

[0001] The utility model relates to solid waste recycling technology and recycling equipment, specifically, a treatment device for concentrating cyanide-containing waste gold plating solution. Background Art

[0002] In the process of PCB manufacturing, the gold plating process is an important electroplating section. Most domestic and foreign enterprises adopt cyanide electroplating technology, which makes the cyanide gold plating waste liquid, gold stripping solution containing cyanide and the washing water of the gold stripping solution, i.e., cyanide-containing waste gold plating solution, contain a certain concentration of highly toxic cyanide ions CN- and precious metal gold. If directly discharged into the environment, it will inevitably cause serious pollution and waste of resources.

[0003] Therefore, the harmless treatment and resource recovery of cyanide-containing waste gold plating solution not only meet the increasingly strict environmental protection requirements, but also recover gold, save enterprise resources, reduce production costs, and truly achieve a win-win situation for environmental and economic benefits.

[0004] However, when the concentration of cyanide-containing waste gold plating solution is low, the treatment time is long, and it is impossible to carry out rapid and efficient treatment.

[0005] Therefore, a treatment device for concentrating cyanide-containing waste gold plating solution is needed to solve the above problems. Summary of the Utility Model

[0006] The purpose of the utility model is to provide a treatment device for concentrating cyanide-containing waste gold plating solution.

[0007] The utility model realizes the above purpose through the following technical solutions:

[0008] A treatment device for concentrating cyanide-containing waste gold plating solution includes a closed box for containing cyanide-containing waste gold plating solution. An inlet is arranged on the left side of the closed box, and an outlet for the concentrated solution is arranged on the right side.

[0009] An evaporation plate is arranged on the inner wall of the closed box. Correspondingly, a water-lifting component is also arranged in the closed box. The water-lifting component consists of a stirring water wheel, and the stirring water wheel is used as a stirring and lifting part for the cyanide-containing waste gold plating solution to increase the contact between the cyanide-containing waste gold plating solution and the evaporation plate. The evaporation plate is used as a heating and evaporation part. After the water is evaporated, it is discharged through the water vapor discharge part on the upper cover of the closed box, forming an efficient concentration structure for the cyanide-containing waste gold plating solution.

[0010] Further, at least the upper parts of the front inner wall and the rear inner wall of the closed box are provided with evaporation plates.

[0011] Further, a water baffle is also arranged above the stirring water wheel.

[0012] Further, the water baffle is composed of an evaporation plate.

[0013] Furthermore, the water vapor discharge part is composed of a plurality of exhaust holes opened on the upper cover of the closed box body.

[0014] Furthermore, an observation window is provided on the closed box body.

[0015] Furthermore, a sampling and detection port is provided on the closed box body.

[0016] Furthermore, a handling handle is also provided outside the closed box body.

[0017] Compared with the prior art, the utility model pre-concentrates the gold-containing cyanide waste gold plating solution before treatment through an efficient gold-containing cyanide waste gold plating solution concentration structure, effectively improving the subsequent treatment efficiency of the gold-containing cyanide waste gold plating solution.
