Since precious metals have high value, the treatment and recycling of precious metal waste liquid can not only save resources, but also reduce production costs and reduce pollution to the environment. This device is a treatment device for recycling precious metal waste liquid, which is used to replace and separate precious metal ions in precious metal waste liquid.

[0003] After searching, the Chinese patent application No. 202022298664.4 discloses a replacement reaction tank for precious metal recovery, including a tank body, an inverted U-shaped plate is fixedly connected to the middle position of the upper end of the tank body, the middle position of the upper end of the inverted U-shaped plate is fixedly connected to a driving motor, a rotating shaft is movably installed inside the tank body, the annular outer end of the upper side of the rotating shaft is rotatably connected to a T-shaped cylinder, and the left and right ends of the lower side of the straight cylinder of the T-shaped cylinder are fixed with connecting plates, and the connecting plate is fixedly connected to a vertical scraper away from one end of the T-shaped cylinder, and the annular outer end of the upper side of the rotating shaft is slidably connected to a limiting plate, and the limiting plate is fixedly connected to at least two positioning columns arranged in an annular manner at an edge position facing one end of the T-shaped cylinder at an equal distance, and at least two positioning holes arranged in an annular manner are equidistantly provided at the edge position of one end of the T-shaped cylinder facing the limiting plate.
