Description

Technical Field

[0001] This application relates to the field of cadmium sponge blistering technology, and more particularly to an automatic cadmium sponge blistering system. Background Technology

[0002] In the hydrometallurgical zinc refining process, copper and cadmium slag are produced during the purification and impurity removal stages. The zinc and cadmium content ranges from 10% to 40%. This slag is oxidized and then leached with sulfuric acid to produce zinc sulfate and cadmium sulfate solutions. The cadmium in the solutions is replaced with zinc powder to obtain sponge cadmium containing 5% to 10% zinc. This sponge cadmium is then pressed into briquettes for the production of refined cadmium. Cadmium production involves three main steps: sponge cadmium briquetting, crude cadmium reduction smelting, and refined cadmium vacuum distillation. The quality of the sponge cadmium briquettes directly affects the product quality in the subsequent crude cadmium reduction smelting process.

[0003] Existing wet zinc smelting sponge cadmium briquetting equipment has a low degree of automation. The feeding and briquetting processes still require manual shoveling and stacking, which is labor-intensive. Furthermore, it can negatively impact employee health, increasing the risk of arsine and cadmium poisoning. Utility Model Content

[0042] In the hydrometallurgical zinc refining process, copper and cadmium slag are produced during the purification and impurity removal stages. The zinc and cadmium content ranges from 10% to 40%. This slag is oxidized and then leached with sulfuric acid to produce zinc sulfate and cadmium sulfate solutions. The cadmium in the solutions is replaced with zinc powder to obtain sponge cadmium containing 5% to 10% zinc. This sponge cadmium is then pressed into briquettes for the production of refined cadmium. Cadmium production involves three main steps: sponge cadmium briquetting, crude cadmium reduction smelting, and refined cadmium vacuum distillation. The quality of the sponge cadmium briquettes directly affects the product quality in the subsequent crude cadmium reduction smelting process. Existing hydrometallurgical sponge cadmium briquetting equipment has a low degree of automation; manual shoveling and stacking are required during the feeding and briquetting processes, resulting in high labor intensity. This also poses a health risk to workers, increasing the risk of arsine and cadmium poisoning.

[0043] To address the aforementioned issues, this application provides an automatic cadmium sponge briquetting system. This system filters the cadmium sponge replacement solution through a solid-liquid separation tank, and a feeding robot transfers the cadmium sponge into a feeder. The feeder then evenly feeds the cadmium sponge into the briquetting machine hopper. After the briquetting machine completes the briquetting and discharging process, a picking robot neatly stacks the cadmium briquetting clumps and transports them to the next process flow. The entire process is automated and interlocked, reducing safety risks and labor intensity.

[0044] The technical solutions of the embodiments of this application are described in detail below with reference to the accompanying drawings.

First protective railing; 10. Second protective railing; 11. Water vapor collection device; 12. Electric gate valve pipeline; 13. Recovery well; and 14. Engineering pump.

[0048] The control cabinet 7 is installed outside the solid-liquid separation tank 1 and the dough press 4, and needs to meet the condition of being able to observe the operation of the solid-liquid separation tank 1 and the dough press 4 simultaneously. The control cabinet 7 is connected to the material handling robot 2, the feeder 3, the dough press 4, the cake-taking robot 5, and the weighing and transferring machine 6, and controls the operation of the material handling robot 2, the feeder 3, the dough press 4, the cake-taking robot 5, and the weighing and transferring machine 6 through the control cabinet 7.

[0049] A material handling robot 2 is installed between the feeder 3 and the solid-liquid separation tank 1. The robot 2 picks up sponge cadmium and moves it to the front end of the feeder 3. The robot 2 includes a robot arm, a material handling clamp, and a control system. The robot arm is a six-axis industrial version, and the material handling clamp is mounted on it. The clamp is bucket-shaped and matches the shape of the inner tank of the solid-liquid separation tank 1, completely covering it. The control system is mounted on the control cabinet 7. The control system uses a matrix sweeping method, controlling the material handling robot 2 to pick up materials according to the scale lines in the solid-liquid separation tank 1, achieving the function of picking up most of the materials. After the control program completes, workers use high-pressure water guns and other tools to rinse the remaining material in the solid-liquid separation tank 1, which then flows into the recovery well 13 for secondary replacement.

[0050] The solid-liquid separation tank 1 is divided into upper and lower layers. The upper layer is a sponge cadmium storage area, and the lower layer is a filtrate storage area. The sponge cadmium storage area uses modular filter screen modules for easy maintenance and cleaning. A graduated scale is installed on the sponge cadmium storage area. A push plate is installed on one side of the sponge cadmium storage area to concentrate the upper layer of sponge cadmium in the solid-liquid separation tank 1 to the other side, facilitating the grabbing of the sponge cadmium by the material handling robot 2. The solid-liquid separation tank 1 is made of stainless steel, and its internal dimensions are 2500×1500×1000mm. A water vapor collection device 11 is installed above the solid-liquid separation tank 1 to extract water vapor generated by the solid-liquid separation tank 1. A recovery well 13 is located on one side of the solid-liquid separation tank 1. The lower filtrate storage area of ​​the solid-liquid separation tank 1 is connected to the recovery well 13. An electric gate valve pipeline 12 connects the recovery well 13 and the solid-liquid separation tank 1. An engineering pump 14 pumps the sponge cadmium that has settled in the recovery well 13 to the solid-liquid separation tank 1, completing the primary and secondary replacement of materials in the recovery well 13.

[0051] The feeder 3 is connected to the briquetting machine 4 at its rear end and operates in conjunction with the briquetting machine 4. The feeder 3 centrally stores and delivers the material grabbed by the robotic arm 2 in a fixed volume manner, and can balance the unstable material grabbing volume of the robotic arm 2. The briquetting machine 4 is program-driven. After the material is delivered by the feeder 3, it automatically performs the briquetting action and discharges the cake to a lower platform.

[0052] The protective door 8 is installed between the control cabinet 7 and the solid-liquid separation tank 1. The briquetting machine 4 and the material handling robot 2 are interlocked with the protective door 8. The protective door 8 is equipped with a sensor. When the protective door 8 is opened, the control cabinet 7 issues a stop command, the material handling robot 2 stops running, and the feeder 3 and the briquetting machine 4 also stop running immediately after completing the program of the most recent sponge cadmium cake. They will only start running again after the protective door 8 is closed and the machine is manually restarted by the control cabinet 7.

[0053] A robotic arm 5 is installed between the dough press 4 and the weighing transfer machine 6. The robotic arm 5 picks up the sponge cadmium cake and transfers it to the weighing transfer machine 6. The gripper of the robotic arm 5 is a wire box that matches the shape of the sponge cadmium cake dough produced by the dough press 4. A ton bag is hung on the weighing transfer machine 6. The robotic arm 5 picks up the cake dough and places it into the ton bag already hung on the weighing transfer machine 6, stacking them in the same direction. When the mass of the sponge cadmium cake dough in the ton bag reaches the set value, the weighing transfer machine 6 transports the packed ton bag to the next process.

[0054] The first guardrail 9 is installed on the outside of the material handling robot 2, the feeder 3 and the dough press 4, and the second guardrail 10 is installed on the outside of the cake taking robot 5 and the weighing transfer machine 6. The first guardrail 9 and the second guardrail 10 are used for on-site protection.
