Description

Technical Field

[0001] This utility model relates to the field of precious metal adsorption treatment technology, and in particular to a multi-stage continuous adsorption and separation device for precious metals. Background Technology

[0002] Metals mainly refer to gold, silver, and the platinum group metals, such as the eight metallic elements ruthenium, rhodium, palladium, osmium, iridium, and platinum. Precious metals are relatively chemically stable under normal conditions and have excellent corrosion resistance. Due to their good electrical conductivity, oxidation resistance, and stability, precious metals are widely used in the electronics industry.

[0003] To alleviate resource shortages, traditional methods such as pyrometallurgy and hydrometallurgy are commonly used to extract precious metals. However, the recovery rate of pyrometallurgy is often not ideal, and the hydrometallurgical process is usually more complex and has a longer operation cycle. In order to extract more precious metals with simple operation, a multi-stage continuous adsorption and separation device for precious metals is needed.

[0004] In existing multi-stage continuous adsorption separation devices for precious metals, the precious metal raw solution is injected into the separation adsorption tank, and the resin material in the adsorption tank adsorbs the precious metals in the raw solution. However, when different raw solutions are injected, a large amount of resin accumulates together, which causes some of the precious metals in the raw solution to be unable to be adsorbed by the resin, resulting in insufficient adsorption of the raw solution and reducing the adsorption efficiency of the resin. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a multi-stage continuous adsorption and separation device for precious metals, which aims to improve the problem in the prior art where a large amount of resin accumulates together, making it impossible to fully adsorb the original solution.

Third air pipes are equidistantly connected to the outer walls of the second air pipe. Air holes are equidistantly opened on the outer walls of the multiple third air pipes. A filtration mechanism is provided on the upper left side of the inner side of the first adsorption tank. The filtration mechanism is used to filter larger impurities in the original liquid.

[0007] As a further description of the above technical solution:

[0008] The filtration mechanism includes a third rotating rod and a transmission belt. The bottom end of the third rotating rod is fixedly connected to the other end of the dual-head motor. A fourth rotating rod is rotatably connected to the top center of the first adsorption tank.

One end of the first water pump is connected to an infusion pipe, and the other end of the first water pump is connected to a first water inlet pipe. The first water inlet pipe is connected to the left water inlet.

[0011] As a further description of the above technical solution:

[0012] The bottom of the first adsorption tank is connected to a first water outlet pipe, and the top rear side of the base is fixedly connected to a second water pump.

[0022] 1. In this utility model, when the dual-head motor and air pump are started, the dual-head motor drives the first bevel gear to rotate, which in turn drives the first air tube to rotate through the second rotating rod. The air pump injects gas into the L-shaped rod, which then passes through the first air tube to the third air tube. The gas blows through the air holes to agitate the resin inside, thereby allowing the resin and the original liquid to mix thoroughly. This allows for the full adsorption of precious metals in the original liquid, improving the adsorption efficiency of the resin.

An air pump 10 is fixedly connected to the upper middle part of the left side of the outer wall of the first adsorption tank 3. The right end of the air pump 10 passes through the first adsorption tank 3 and is connected to an L-shaped tube 11. The left end of the air pump 10 is connected to an air supply pipe 35. One end of the L-shaped tube 11 is rotatably connected to a first air pipe 12. A third bevel gear 13 is fixedly connected to the upper middle part of the outer wall of the first air pipe 12. The third bevel gear 13 meshes with the fourth bevel gear 14. A second air pipe 15 is connected to the lower side of the outer wall of the first air pipe 12. The outer wall of the tube 15 is equidistantly connected to third air pipes 16. The outer walls of the multiple third air pipes 16 are equidistantly provided with air holes 17. A filter mechanism 2 is provided in the upper inner part of the first adsorption tank 3. The filter mechanism 2 is used to filter larger impurities in the original solution.

The second adsorption tank 18 is fixedly connected to the right side of the rear end of the top of the base 1. A U-shaped rod 19 is fixedly connected to the middle of the top of the base 1. A first water pump 20 is fixedly connected to the right side of the top of the U-shaped rod 19. One end of the first water pump 20 is connected to... The infusion tube 34, the other end of the first water pump 20 is connected to the first water inlet pipe 21, the first water inlet pipe 21 is connected to the left water inlet 25, the bottom end of the first adsorption tank 3 is connected to the first water outlet pipe 22, the top rear side of the base 1 is fixedly connected to the second water pump 23, the other end of the first water outlet pipe 22 is connected to the second water pump 23, one end of the second water pump 23 is connected to the second water inlet pipe 24, the other end of the second water inlet pipe 24 is connected to the right water inlet 25, the bottom end of the second adsorption tank 18 is connected to the second water outlet pipe 32, and a one-way valve 33 is provided in the middle of the outer wall of the second water outlet pipe 32;

[0033] Specifically, first, the air pump 10 and the dual-head motor 5 are started. The dual-head motor 5 begins to rotate, and the first rotating rod 6 begins to rotate. The first rotating rod 6 is connected to the first bevel gear 7. When the first rotating rod 6 rotates, the first bevel gear 7 also rotates. As the first bevel gear 7 rotates, it meshes with the second bevel gear 9, thereby driving the second bevel gear 9 to start rotating as well. The second bevel gear 9 is connected to the third bevel gear 13 through the second rotating rod 8, thereby driving the third bevel gear 13 to start rotating as well. The third bevel gear 13 meshes with the fourth bevel gear 14. Therefore, when the third bevel gear 13 rotates, the fourth bevel gear 14 is also driven. The fourth bevel gear 14 meshes with the fourth bevel gear 14. A first air pipe 12 is connected, which will drive the first air pipe 12 to rotate together. During this process, the air pump 10 injects air into the first air pipe 12 through the L-shaped pipe 11. The injected air will pass through the first air pipe 12, and then enter the third air pipe 16 through the second air pipe 15. The air will be ejected through the air hole 17. The ejected gas will blow the accumulated adsorption resin, so that the resin and the precious metal raw liquid can be fully mixed. After the first adsorption tank 3 has adsorbed, the second water pump 23 is started to put the raw liquid treated by the first adsorption tank 3 into the second adsorption tank 18 for a second adsorption. After that, it can flow out through the second water outlet pipe 32.

[0034] Reference Figure 2 and Figure 5 The filter mechanism 2 includes a third rotating rod 201 and a transmission belt 204. The bottom end of the third rotating rod 201 is fixedly connected to the other end of the double-headed motor 5. The top center of the first adsorption tank 3 is rotatably connected to a fourth rotating rod 202. The top of the outer wall of the fourth rotating rod 202 and the top of the outer wall of the third rotating rod 201 are both fixedly connected to pulleys 203. The two pulleys 203 are connected by transmission belt 204. The bottom end of the fourth rotating rod 202 is fixedly connected to a cleaning rod 205. The left and right sides of the inner wall of the first adsorption tank 3 are both fixedly connected to limit blocks 206. The top of the two limit blocks 206 is fixedly connected to the same filter screen 207. The middle of the inner wall of the first adsorption tank 3 is fixedly connected to a first fixing block 27. The middle of the outer wall of the first fixing block 27 is fixedly connected to a hollow box 28. One end of the first air pipe 12 and the second rotating rod 8 respectively penetrate the hollow box 28.

[0035] Specifically, the third rotating rod 201 is driven by a dual-head motor 5. When the third rotating rod 201 starts to rotate, it drives the pulley 203 connected to it. The pulley 203 is connected to another pulley 203 on the left side through a transmission belt 204. When the pulley 203 on the left side starts to rotate, it further drives the fourth rotating rod 202. The rotation of the fourth rotating rod 202 drives the cleaning rod 205 to rotate. The raw liquid will be initially filtered by the filter screen 207 after entering the first adsorption tank 3. The filter screen 207 will retain larger impurities. The stirring action of the cleaning rod 205 will further promote the flow of the raw liquid, so that the remaining raw liquid can smoothly enter the lower part of the equipment.

[0036] Reference Figure 1 A controller 26 is fixedly connected to the front top of the base 1. The controller 26 is electrically connected to the dual-head motor 5, the air pump 10, the first water pump 20 and the second water pump 23 respectively. An observation window 31 is provided in the middle of the outer wall of the first adsorption tank 3.

[0037] Specifically, a controller 26 is installed in front of the base 1. The controller 26 can control the operation of the dual-head motor 5, the air pump 10, the first water pump 20, and the second water pump 23. The model of the dual-head motor 5 is SMD-T25-30, the model of the air pump 10 is DQE1320-30L, and the models of the first water pump 20 and the second water pump 23 are both 300QSZ-3.4-13. The internal condition of the first adsorption tank 3 can be observed through the observation window 31.

[0038] Reference Figure 2 and Figure 3 A second fixing block 29 is fixedly connected to the top left side of the inner wall of the first adsorption tank 3, and a diversion block 30 is fixedly connected to the middle of the outer wall of the second fixing block 29.

[0039] Specifically, when the raw liquid enters the interior through the inlet 25 of the first adsorption tank 3, the impact force generated when the raw liquid enters can be buffered by the diversion block 30.

[0040] Working principle: Start the first water pump 20 to draw the raw liquid from the raw liquid pool into the first adsorption tank 3. Start the air pump 10 and the dual-head motor 5. The first rotating rod 6 will drive the first bevel gear 7 to rotate. At this time, the second bevel gear 9 is driven, which drives the third bevel gear 13 through the second rotating rod 8. The fourth bevel gear 14, which meshes with the third bevel gear 13, is driven, thereby causing the first air pipe 12 to rotate. At the same time, the second air pipe 15 and the third air pipe 16 on the lower side will rotate together. The air pump 10 will inject air into the first air pipe 12 through the L-shaped pipe 11, and then enter the third air pipe 16 through the second air pipe 15 and be sprayed out through the air hole 17. The sprayed gas will blow the adsorption resin that is piled up together, so that the resin and the precious metal raw liquid can come into full contact.

[0041] Furthermore, when the raw liquid is injected into the first adsorption tank 3, some of the raw liquid may contain large impurities that have not been cleaned. The dual-head motor 5 drives the third rotating rod 201, which in turn drives the pulley 203 fixed on it. The pulley 203 on the left side is driven by the transmission belt 204, which in turn drives the fourth rotating rod 202. The fourth rotating rod 202 drives the cleaning rod 205 to rotate, and the raw liquid enters the first adsorption tank 3. The filter screen 207 will filter again, leaving the large impurities on top. The cleaning rod 205 is used to stir the liquid so that the remaining raw liquid can enter the lower side for adsorption.

[0042] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
