Description

Technical Field

[0001] This utility model relates to the field of metal recycling technology, specifically to an electrolytic purification device for gold and silver precious metals. Background Technology

[0002] Electrolytic purification equipment for gold and silver precious metals is a specialized device used to extract high-purity gold, silver, and other precious metals (such as platinum, palladium, and rhodium) from crude metals or precious metal-containing waste through electrolysis. This type of equipment is widely used in mining smelting, electronic waste recycling, electroplating wastewater treatment, and precious metal refining plants, and can increase metal purity to 99.99% or even higher than 99.999%.

[0003] Electrolytic refining of gold and silver is a common method for refining precious metals. It separates gold and silver from alloys or other mixtures using electrochemical means. The electrolysis process involves using a gold-silver alloy as the anode and pure gold or an inert material as the cathode, through an electrolyte solution. During this process, gold is reduced and deposited on the cathode, while silver forms silver chloride, which is collected in the anode bag. After electrolysis, pure gold is collected from the cathode, and silver chloride is collected from the anode bag. Further processing can convert the silver chloride back into pure silver.

[0004] During purification, the electrolyte is usually in a static state, while the two electrodes are typically located on opposite sides of the electrolytic cell. This can easily lead to a rapid decrease in the concentration of electrolyte ions near the electrodes, while the ions in the electrolyte in the middle are not replenished in time, resulting in uneven reaction. This not only makes it easy for the electrolyte to be not fully utilized, but also reduces the efficiency of electrolytic purification. Furthermore, the anode of the existing electrolytic purification device needs to be encased in an external anode bag, which is inconvenient to use. Utility Model Content

[0005] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a gold and silver precious metal electrolytic purification device, which can effectively solve the problems mentioned in the background technology.

[0006] To achieve the above objectives, this utility model provides the following technical solution: This utility model provides a gold and silver precious metal electrolytic purification device, including an outer shell. A support rod is fixed to the middle of the top of the outer shell. A protective shell is fixed to the middle of the top of the support rod. An air pump is fixed to the top of the protective shell via a connecting seat. An air outlet of the air pump is sealed and connected to an air guide pipe. A first connecting shaft is fixed to the power output end inside the air pump. A driving gear is fixed to the outer wall of the first connecting shaft. A driven gear is rotatably connected through the middle of the bottom of the inner wall of the protective shell. A second connecting shaft is fixed to the outer wall of the driven gear. A fourth connecting rod is fixed to the bottom of the second connecting shaft. A stirring rod is fixed to the bottom of one end of the fourth connecting rod.

[0007] Furthermore, the bottom end of the first connecting shaft is rotatably connected to the inner wall of the protective shell, the driving gear and the driven gear mesh with each other, and the diameter of the driving gear is smaller than the diameter of the driven gear.

[0008] Furthermore, there are three fourth connecting rods and three stirring rods, which are arranged equidistantly in a circle, and the bottom end of the air guide tube and the bottom end of the stirring rod are located on the same horizontal plane.

[0009] Furthermore, each of the two ends of the outer casing has a through-hole opening at the top, and a first connecting rod and a third connecting rod are respectively placed inside the two placement slots. A cathode plate is fixed to the bottom of the third connecting rod.

[0010] Furthermore, a second connecting rod is fixed to the bottom of both ends of the first connecting rod, and a container is fixed to the bottom of the two second connecting rods. The side wall of the container is evenly covered with multiple mesh holes.

[0011] Furthermore, a base plate is fixed to the bottom of the inner wall of the outer shell, and a drain pipe is sealed and connected through one side of the bottom of the outer wall of the outer shell. A valve is provided on the outside of the drain pipe, the top of the base plate is inclined, and the drain pipe is located on the side of the base plate with a smaller thickness.

[0012] The technical solution provided by this utility model has the following advantages compared with the known prior art: 1. This application operates using an air pump. The internal fan blades of the air pump rotate, which drives the first connecting shaft to rotate, thereby driving the drive gear to rotate. This causes the driven gear and the second connecting shaft to rotate slowly. The second connecting shaft drives three stirring rods to rotate slowly inside the electrolyte, stirring and mixing the electrolyte. At the same time, the air pump generates airflow, which is introduced into the electrolyte through the air guide tube. The airflow forms bubbles in the electrolyte and also has a certain stirring function, thereby achieving the effect of maintaining a uniform distribution of electrolytic ions inside the electrolyte during electrolysis and improving the utilization rate of the electrolyte.

[0013] 2. This application allows the cathode plate to be placed inside the outer casing by directly placing the third connecting rod inside the placement slot after installing the electrode. The gold and silver metal materials to be electrolyzed are placed inside the holding box and then placed inside the outer casing via the first connecting rod. The silver ions after electrolysis form silver chloride and enter the holding box. When discharging waste electrolyte, the valve can be opened for discharge. The bottom plate can better discharge the electrolyte inside the outer casing through the drain pipe, thus achieving a more convenient use. Attached Figure Description

The driving gear 17 and the driven gear 18 mesh with each other, and the diameter of the driving gear 17 is smaller than the diameter of the driven gear 18. During electrolytic purification, the air pump 14 is started. The fan blades inside the air pump 14 rotate, and the operation of the air pump 14 drives the first connecting shaft 16 to rotate, thereby driving the driving gear 17 to rotate, so that the driven gear 18 and the second connecting shaft 19 rotate slowly.

The three fourth connecting rods 20 are arranged in a circumferentially equidistant manner. The bottom end of the air guide pipe 15 and the bottom end of the stirring rod 21 are located on the same horizontal plane. The second connecting shaft 19 drives the three stirring rods 21 to rotate slowly inside the electrolyte, stirring and mixing the electrolyte. At the same time, the air pump 14 works to generate airflow, which is introduced into the electrolyte from the air guide pipe 15. The airflow forms bubbles in the electrolyte, and also has a certain stirring function.

The first connecting rod 5 and the third connecting rod 8 are placed in the two placement grooves 2 respectively. The cathode plate 9 is fixed at the bottom of the third connecting rod 8. When performing electrolytic purification, the third connecting rod 8 is placed directly in the placement groove 2 to overlap when installing the electrode, so that the cathode plate 9 can be placed inside the outer shell 1.

[0023] Reference Appendix Figure 1 The bottom of both ends of the first connecting rod 5 is fixed with a second connecting rod 6. The bottom of the two second connecting rods 6 is fixed with a holding box 7. The side wall of the holding box 7 is evenly covered with multiple mesh holes.

At the same time, air pump 14 works to generate airflow, which is introduced into the electrolyte through air pipe 15. The airflow forms bubbles in the electrolyte and also has a certain stirring function. After purification, the first connecting rod 5 and the third connecting rod 8 are taken out. When waste electrolyte needs to be discharged, valve 4 can be opened for discharge. The bottom plate 10 can better discharge the electrolyte inside the outer shell 1 through the drain pipe 3.
