Description

Technical Field

[0001] The utility model relates to the technical field of metal recycling, in particular to a device for recycling palladium metal. Background Art

[0002] With the development of modern industry, due to its unique chemical and physical properties, palladium metal has been widely used in the fields of electronics, chemical industry, medicine, etc. However, the reserves of palladium resources are limited and the mining cost is relatively high. Therefore, recycling palladium from palladium-containing waste has become an important research direction.

[0003] As a common palladium recycling technology, hydrometallurgy, however, has some significant problems in the implementation process. First of all, the precipitates after palladium dissolution are often difficult to be quickly and effectively collected, which not only increases the workload of operators, but also affects the recycling efficiency and the processing speed of subsequent processes. Secondly, a large amount of waste water generated during the hydrometallurgy process contains various organic substances, resulting in an increase in water chroma and emitting odors. If these components are directly discharged into the environment without proper treatment, it will cause serious environmental pollution problems. Summary of the Utility Model

[0027] Next, in combination with the drawings and specific embodiments, the present utility model will be further described. It should be noted that, on the premise of no conflict, the following-described embodiments or technical features can be arbitrarily combined to form new embodiments.

[0028] Embodiment:

[0029] Please refer to Figures 1-5 , A device for recovering metal palladium in this embodiment includes a reaction tank 1. A sliding groove 2 is provided on the inner wall of the reaction tank 1. A lifting assembly 3 is arranged on the upper surface of the reaction tank 1. Four corners of the lower surface of the reaction tank 1 are fixedly connected with first corner pads 4;

[0030] The lifting component 3 includes a first motor 301, the first motor 301 is fixedly connected to the upper surface of the reaction tank 1, the output end of the first motor 301 is fixedly connected with a threaded rod 302, the bottom end of the threaded rod 302 is threadedly connected with an adapter sleeve 303, the bottom end of the adapter sleeve 303 is fixedly connected with an extended cross plate 304, both sides of the extended cross plate 304 are fixedly connected with movable sliders 305, the movable sliders 305 are slidably connected to the inside of the sliding groove 2, the outer surface of the movable sliders 305 is fixedly connected with a collection frame 306. When it is necessary to lift the collection frame 306, the operator starts the first motor 301, the output end of the first motor 301 drives the threaded rod 302 to rotate. Since the threaded rod 302 is threadedly connected with the adapter sleeve 303, the rotation of the threaded rod 302 causes the adapter sleeve 303 to move up and down along the threaded rod 302. The movement of the adapter sleeve 303 drives the extended cross plate 304 and the movable sliders 305 fixed to it to move up and down together. The movement of the movable sliders 305 further drives the collection frame 306 to lift and lower. Since the movable sliders 305 are slidably connected to the inside of the sliding groove 2, it ensures the stability and smoothness of the collection frame 306 during the lifting and lowering process. The surface of the collection frame 306 is provided with a number of water leakage holes, which can drain the liquid during the lifting process, so as to fish and collect the precipitate formed after the palladium ion reaction. When the collection frame 306 rises to a certain height, the operator can conveniently take out the precipitate containing palladium ions from the collection frame 306. After the collection is completed, the first motor 301 is started in reverse to make the collection frame 306 descend to its original position to prepare for the next collection work, and the operation is simple and convenient.

[0031] The lower surface of the first angle pad 4 is fixedly connected with a waste water tank 5. A viewing window 6 is arranged at the front end of the waste water tank 5. The operator can monitor the liquid level height in the waste water tank 5 in real time through the viewing window 6. When it is observed that the liquid level in the waste water tank 5 is close to the maximum capacity, the operator can take timely measures to discharge the waste water to the designated treatment facilities to prevent the waste water from overflowing.

[0032] A control panel 7 is arranged at the front end of the waste water tank 5. A feeding groove 8 is arranged on the upper surface of the waste water tank 5. The design of the feeding groove 8 ensures the accuracy of reagent addition. The waste water undergoes a chemical reaction in the waste water tank 5 to form insoluble precipitates of metal ions. The precipitated metal compounds can be removed from the waste water through subsequent solid-liquid separation processes, thereby realizing the purification of the waste water.

[0033] The outer surface of the waste water tank 5 is fixedly connected with a second motor 9, and the output end of the second motor 9 is fixedly connected with a transmission shaft 10.

[0034] The outer surface of the transmission shaft 10 is fixedly connected with stirring support rods 11. An activated carbon fine filter screen 12 is arranged on the inner wall of the wastewater tank 5. The transmission shaft 10 drives the stirring support rods 11 to rotate, so that the wastewater and chemical reagents in the wastewater tank 5 are fully mixed. The stirring process accelerates the progress of the chemical reaction, enabling metal ions to form precipitates more quickly. The activated carbon fine filter screen 12 utilizes the adsorption property of activated carbon to remove organic matters, color and odor in the wastewater. For the wastewater after the chemical reaction, the precipitated metal compounds are removed from the wastewater through the filtering process of the activated carbon fine filter screen 12. The activated carbon fine filter screen 12 can further intercept fine particles and suspended matters to ensure the water quality of the effluent, and then purify the wastewater.

[0035] The middle part of the lower surface of the wastewater tank 5 is fixedly connected with a threaded connecting pipe 13. Drainage holes are provided in the middle of the inner bottom wall of the reaction tank 1 and the middle of the upper surface of the wastewater tank 5. A valve is arranged on the lower surface of the drainage hole. The threaded connecting pipe 13 facilitates subsequent connection with external pump equipment by personnel, so as to discharge the neutralized and purified wastewater to the outside.

[0036] The four corners of the lower surface of the wastewater tank 5 are all fixedly connected with second corner pads 14.

[0037] In the embodiment of the present application, the implementation principle of a device for recovering palladium metal is as follows: First, the operator adds the palladium-containing wastewater to be treated into the reaction tank 1, and then adds a precipitant. After adding the precipitant, the palladium ions in the solution will react with the precipitant to form insoluble precipitates. At this time, the operator starts the first motor 301, and the output end of the first motor 301 drives the threaded rod 302 to rotate. Since the threaded rod 302 is threadedly connected to the connecting sleeve 303, the rotation of the threaded rod 302 causes the connecting sleeve 303 to move up and down along the threaded rod 302. The movement of the connecting sleeve 303 drives the extending cross plate 304 and the movable slider 305 fixed to it to move up and down together. The movement of the movable slider 305 further drives the collection frame 306 to lift and lower. Since the movable slider 305 is slidably connected to the inside of the sliding groove 2, it ensures the stability and smoothness of the collection frame 306 during the lifting and lowering process. The surface of the collection frame 306 is provided with a number of water leakage holes, which can discharge the liquid during the lifting process, so as to salvage and collect the precipitates formed after the reaction of palladium ions. When the collection frame 306 rises to a certain height, the operator can conveniently take out the precipitates containing palladium ions from the collection frame 306. After the collection is completed, the first motor 301 is started in reverse to make the collection frame 306 descend to its original position to prepare for the next collection work. The operation is simple and convenient. Subsequently, the operator opens the valve to make the wastewater inside the reaction tank 1 flow to the wastewater tank 5 through the drain hole. The upper surface of the wastewater tank 5 is provided with a feeding trough 8. The operator adds chemical reagents to the inside of the wastewater tank 5 through the feeding trough 8, and then starts the second motor 9 to drive the transmission shaft 10 and the stirring support rod 11 to rotate, so that the wastewater and the chemical reagents in the wastewater tank 5 are fully mixed. The stirring process accelerates the progress of the chemical reaction and makes the metal ions form precipitates faster. The activated carbon fine filter screen 12 uses the adsorption performance of activated carbon to remove organic substances, color and odor in the wastewater. After the chemical reaction, the wastewater passes through the filtration process of the activated carbon fine filter screen 12 to remove the precipitated metal compounds from the wastewater. The activated carbon fine filter screen 12 can further intercept fine particles and suspended substances to ensure the water quality of the effluent, and thus purify the wastewater.

[0038] The above-mentioned implementation manners are only the preferred implementation manners of the present invention, and cannot be used to limit the scope of protection of the present invention. Any non-substantial changes and substitutions made by those skilled in the art based on the present invention belong to the scope of protection required by the present invention.
