Description

Technical Field

[0001] This utility model relates to the technical field of waste liquid treatment devices, and in particular to an electrolytic waste liquid treatment device in hydrometallurgical zinc production. Background Technology

[0002] Hydrometallurgical zinc refining is a process that extracts zinc through chemical reactions. It mainly includes three steps: leaching, purification, and electrolysis. Zinc-containing ore is crushed and mixed with an acidic solution to form a leachate. Zinc dissolves in the liquid through a chemical reaction. After purification steps such as filtration and precipitation, impurities are removed, resulting in a solution with a high zinc content. The purified zinc solution is then subjected to an electrolysis process, where an electric current is used to reduce zinc ions to zinc metal, which is deposited on the cathode of the electrolytic cell. Hydrometallurgical zinc refining has the advantage of being able to process low-grade ores and performs well in terms of zinc recovery and environmental protection.

[0003] In hydrometallurgical zinc production, the electrolytic waste liquid treatment device is used to treat the waste liquid generated during the electrolysis process, ensuring environmental protection and resource recycling. After treatment, the waste liquid is further filtered to remove fine suspended solids and remaining impurities. The waste liquid that meets the standards can be discharged or reused in the production process, while the waste liquid that does not meet the standards needs to be further treated. This treatment device not only effectively reduces environmental pollution, but also recovers valuable resources and improves the overall economic efficiency of production.

[0004] During the treatment of electrolytic waste liquid, other chemical reagents need to be added to accelerate the reaction rate. However, in actual use, some chemical reagents need to be prepared in a one-to-one ratio according to the volume of waste liquid to be treated. Therefore, manual preparation by staff is required, which increases the workload of the staff. Utility Model Content

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figure 1 , Figure 2 and Figure 5 This utility model provides an embodiment of an electrolytic waste liquid treatment device for hydrometallurgical zinc production, comprising a base plate 1, an electrolytic cell 3 fixedly connected to the top left side of the base plate 1, a sealing plate 4 slidably connected to the middle of the inner wall of the electrolytic cell 3, a fixing block 5 fixedly connected to the bottom of the sealing plate 4, rotating bars 6 rotatably connected to the left and right sides of the bottom of the fixing block 5, sliding blocks 7 rotatably connected to the bottom of the rotating bars 6, tension springs 8 fixedly connected to adjacent sides of the two sliding blocks 7, and a moving column fixedly connected to the right side of the right sliding block 7. 9. The right side of the movable column 9 passes through the electrolytic cell 3 and is fixedly connected to a movable plate 10. Multiple movable rods 11 are fixedly connected to the right side of the movable plate 10. A piston 12 is fixedly connected to the right side of the movable rod 11. Multiple sealing rings 13 are fixedly connected to the outside of the piston 12. Multiple injection tanks 14 are fixedly connected to the top center of the bottom plate 1. An outlet 15 is connected to the right side of the injection tank 14. Multiple replenishment mechanisms 2 are provided on the right side of the electrolytic cell 3. The replenishment mechanism 2 is used to replenish the injection tank 14 with reagents.

[0033] Specifically, different agents are filled into the injection tank 14, and then waste liquid is added to the electrolytic cell 3. As the waste liquid gradually increases, the tension spring 8 will be gradually pulled apart, the sliding blocks 7 on both sides will move apart, and the rotating bar 6 above will rotate accordingly, thereby driving the fixed block 5 to move down, and the sealing plate 4 will gradually sink. During the movement of the right sliding block 7, the moving column 9 will move to the right side of the electrolytic cell 3, thereby driving the outer moving plate 10 to move, so that the moving rod 11 and the piston 12 will squeeze the agent in the injection tank 14 through the discharge port 15, thereby realizing the automatic extrusion of the required amount of drug according to the amount of waste liquid added.

[0034] Reference Figure 1 , Figure 2 and Figure 4 The supplementary mechanism 2 includes multiple reagent storage tanks 201, which are fixedly connected to the right side of the outer wall of the electrolytic cell 3. The bottom right side of the outer wall of the reagent storage tank 201 is connected to a conduit 202. A metal pipe 204 is scraped and connected to the outside of the discharge port 15. A one-way valve 203 is connected to the right side of the conduit 202. The one-way valve 203 is connected to the top of the outer wall of the metal pipe 204. A one-way valve 205 is fixedly connected to the right side of the outer wall of the metal pipe 204. A collection box 206 is fixedly connected to the top right side of the bottom plate 1. A filling port 207 is opened on the top of the reagent storage tank 201.

[0035] Specifically, after the waste liquid in the electrolytic cell 3 is cleaned up, the sliding blocks 7 on both sides will move relative to each other under the action of the tension spring 8, causing the moving column 9 to drive the moving plate 10, moving rod 11 and piston 12 above it to move to the left side of the electrolytic cell 3. At this time, the one-way valve 205 will close and the one-way valve 203 will open. As the piston 12 moves, it will generate suction in the injection agent tank 14. At this time, new agent will flow from the agent storage tank 201 to the conduit 202 and enter the injection agent tank 14 through the one-way valve 203 to replenish the agent. When the agent is squeezed out, the one-way valve 203 will close and the one-way valve 205 will open, thereby squeezing the agent into the collection box 206. The agent can be added to the agent storage tank 201 through the filling port 207.

[0036] Reference Figure 1 , Figure 2 and Figure 4 A gas pipe 16 is fixedly connected to the top of the sealing plate 4, and multiple exhaust nozzles 17 are fixedly connected to the top of the gas pipe 16. Multiple electrode plates 18 are fixedly connected to the top of the sealing plate 4. Multiple holes 19 are opened on the right side of the electrode plate 18. A water level groove 20 is opened on the front right side of the outer wall of the medicine storage box 201. A sealing frame 21 is fixedly connected to the outside of the water level groove 20.

[0037] Specifically, the air blown out by the external air blowing device can be guided into the electrolytic cell 3 through the air pipe 16 and discharged through the exhaust nozzle 17, which can intensify the movement of molecules in the waste liquid. The holes 19 can promote the flow of electrolyte and facilitate the discharge of gas. The remaining amount of reagent inside the reagent storage tank 201 can be observed through the water level tank 20.

[0038] Reference Figure 1 , Figure 2 and Figure 5 A limit block 22 is fixedly connected to the rear right side of the outer wall of the drug storage box 201. An information plate 23 is fixedly connected to the right side of the limit block 22. A sliding groove 24 is opened at the bottom of the inner wall of the electrolytic cell 3. Two sliding blocks 7 are slidably connected to the sliding groove 24. A controller 25 is fixedly connected to the front side of the outer wall of the base plate 1. The controller 25 is electrically connected to the electrode plate 18.

[0039] Specifically, the information board 23 can distinguish the medicines stored on the inner wall of the medicine storage box 201, the slide 24 can restrict the movement path of the sliding block 7, and the controller 25 can control the power of the electrode plate 18.

[0040] Working principle: Before using the device, first, the injection tank 14 is filled with the agent. Then, waste liquid is injected into the electrolytic cell 3. As the amount of waste liquid gradually increases, the tension spring 8 gradually extends, causing the sliding blocks 7 on both sides to move separately. At the same time, the rotating bar 6 above rotates, which in turn causes the fixed block 5 to move downward and the sealing plate 4 to gradually descend. During the movement of the right sliding block 7, the moving column 9 is pushed to the right side of the electrolytic cell 3, which in turn drives the outer moving plate 10 to move accordingly. This series of actions causes the moving rod 11 and the piston 12 to squeeze the agent in the injection tank 14 through the discharge port 15. Thus, according to the amount of waste liquid added, the device can automatically squeeze out the required amount of agent.

[0041] Furthermore, through the replenishment mechanism 2, after the waste liquid in the electrolytic cell 3 is cleaned up, the action of the tension spring 8 will cause the sliding blocks 7 on both sides to move relative to each other. At the same time, the moving column 9, together with the moving plate 10, the moving rod 11 and the piston 12 on it, will move to the left side of the electrolytic cell 3. During this process, the one-way valve 205 will close and the one-way valve 203 will open. As the piston 12 moves, a suction force is generated in the injection agent barrel 14, causing new agent to flow from the agent storage tank 201 to the conduit 202, and enter the injection agent barrel 14 through the one-way valve 203, thereby realizing the replenishment of agent. During the extrusion of agent, the one-way valve 203 will close and the one-way valve 205 will open, squeezing the agent towards the collection box 206. Through the filling port 207, the agent can be added to the agent storage tank 201.

[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.
