[0044] Please see Figure 1 The copper-containing wastewater treatment and copper sheet manufacturing apparatus provided in this application embodiment includes: a wastewater treatment component 10 and a copper sludge treatment component 20.
[0045] Wastewater treatment component 10 is used to treat copper-containing wastewater to generate copper-containing precipitate blocks. In this embodiment, the wastewater treatment component 10 can treat copper-containing wastewater and generate copper-containing precipitate blocks using existing treatment methods, such as adding alkaline precipitants like calcium hydroxide or sodium hydroxide, or adding sulfide precipitants to the copper-containing wastewater, and filtering the precipitate after it is formed to obtain copper-containing precipitate blocks.
[0046] The copper sludge treatment assembly 20 includes a furnace 21, a collection tray 22, and a cutter 23. The furnace 21 is used to melt copper-containing precipitates to generate copper sludge. Taking the generation of copper-containing precipitates by adding an alkaline precipitant to copper-containing wastewater as an example, before melting, the copper-containing precipitates generally consist of copper hydroxide and copper oxide, and may also contain oxides of other impurity metal ions originally present in the wastewater. During the melting process of the copper-containing precipitates in the furnace 21, a reducing agent such as coke can be added. During the melting process, the reducing agent reduces the copper oxides or copper oxides with oxides of other impurity metals to obtain pure metallic copper or metallic copper and other metals. The material after the copper-containing precipitates are melted in the furnace 21 is in a molten state, referred to as copper sludge in this embodiment.
[0047] The collecting tray 22 is connected to the discharge port of the furnace 21, so that the copper sludge after the furnace 21 is melted can be transported to the collecting tray 22 for collection; the cutter 23 is used to cut the copper sludge in the collecting tray 22 to produce copper sheets.
[0048] In the device provided in this embodiment, the cutter 23 can directly cut copper sludge into copper sheets, thus eliminating the need for cooling and transfer of copper sludge, thereby improving the utilization rate of copper ions in copper-containing wastewater and the efficiency of copper ion recovery.
[0049] It should be noted that in this embodiment, when treating pure copper-containing wastewater, the resulting copper sludge has a high copper purity; when treating copper-containing wastewater containing other metal impurities, the resulting copper sludge has a low copper purity. Regardless of the type of copper-containing wastewater, it does not affect the operation of the copper sludge treatment component 20 in this solution.
[0050] In a more specific embodiment, the copper sludge treatment assembly 20 further includes: a turntable 24; the turntable 24 is disposed above the collection tray 22 for rolling up the copper sludge on the collection tray 22; and a cutter 23 is disposed beside the turntable 24 for cutting the copper sludge on the turntable 24.
[0051] In this embodiment, the turntable 24 can contact the copper sludge on the collection plate 22 and roll up the copper sludge during the rotation of the turntable 24, so that the copper sludge adheres to the cylindrical outer surface of the turntable 24 and reaches a solidified state, which is convenient for the cutter 23 to cut.
[0052] In this embodiment, the cutter 23 is located beside the turntable 24. After the solidified copper sludge on the turntable 24 accumulates to a certain thickness, it will automatically come into contact with the cutter 23 and be cut into thin sheets.
[0053] As a further improvement, the copper sludge treatment assembly 20 also includes: a support platform 25; a collection tray 22 disposed on the support platform 25; and a turntable 24 that can be raised and lowered on the support platform 25.
[0054] Specifically, a liftable platform can be installed on the support platform 25. The turntable 24 is rotatably mounted on the liftable platform, and the turntable 24 can be raised and lowered by the raising and lowering of the liftable platform. The distance between the turntable 24 and the collection plate 22 can be adjusted by raising and lowering the turntable 24 to control whether the turntable 24 contacts the copper mud and to control the rate at which the turntable 24 picks up the copper mud.
[0055] In one embodiment, the cutter 23 is movably mounted on the support platform 25 in directions toward and away from the turntable 24.
[0056] Specifically, a movable translation stage can be provided on the support platform 25; the cutter 23 is set on the translation stage. The translation stage can drive the cutter 23 to move and adjust the distance between the cutter 23 and the turntable 24, so as to control whether the cutter 23 cuts the copper slurry on the turntable 24 and control the thickness of the slices cut by the cutter 23.
[0057] In one embodiment, the outer periphery of the collection tray 22 is covered with an insulation element 26. In practical applications, the insulation element 26 is insulation cotton.
[0058] The insulation component 26 can maintain the temperature inside the collection pan 22, preventing copper sludge from solidifying inside the collection pan 22.
[0059] In one embodiment, the copper sludge treatment assembly 20 further includes: a funnel plate 27 and a conveying pump 28; the funnel plate 27 is connected to the outlet of the furnace 21 and is disposed below the furnace 21; the conveying pump 28 is connected to the funnel plate 27 and the collection plate 22.
[0060] The funnel-shaped plate 27 has a gradually decreasing cross-sectional area from top to bottom, which facilitates the falling of copper mud, which is then pumped to the collection plate 22 by the transfer pump 28.
[0061] In practical applications, the furnace 21 can also be connected to a collection bucket 29. During the process of melting copper-containing precipitate blocks in the furnace 21, other materials besides copper sludge can be discharged into the collection bucket 29.
[0062] In one embodiment, a material sensor is installed inside the collection pan 22; the material sensor is used to sense the height of the copper sludge inside the collection pan 22; the material sensor is electrically connected to the transfer pump 28. When the liquid level inside the collection pan 22 is high, the transfer pump 28 automatically shuts off; when the liquid level in the collection pan 22 is low, the transfer pump 28 automatically starts, enabling automated control of the copper sludge transfer, reducing manual intervention by personnel, and improving safety.
[0063] In the application, a control valve 210 is installed on the pipeline between the funnel plate 27 and the collection plate 22 to control the opening and closing of the pipeline.
[0064] In one embodiment, the wastewater treatment assembly 10 includes: a stirring tank 11, a feeding tank 12, and a filter press 13; the stirring tank 11 is used to stir copper-containing wastewater; the feeding tank 12 is disposed on the stirring tank 11 and is used to add a precipitant to the stirring tank 11; the filter press 13 is connected to the outlet of the stirring tank 11 and is used to separate copper-containing precipitate blocks from the copper-containing wastewater discharged from the stirring tank 11.
[0065] In this embodiment, the mixing tank 11 is equipped with a stirring paddle for stirring copper-containing wastewater and precipitant. Then, it is pumped to the filter press 13 by the second transfer pump 15 for filtration. The copper-containing precipitate block produced by the filter press 13 after filtration is stored in the storage tank 14.
[0066] In one implementation, the copper-containing precipitate in the storage bin 14 can be manually transferred to the inlet of the furnace 21 by the workers.
[0067] As another implementation, a transfer tool such as a transfer robot can be provided, and the copper-containing precipitate block in the storage tank 14 can be transported to the feed port of the furnace 21 by the transfer tool.
[0068] In one embodiment, the feeding tank 12 is an iron powder tank for storing iron powder; the precipitant is iron powder.
[0069] Specifically, in this embodiment, iron powder enters the copper-containing wastewater, where a displacement reaction occurs, causing copper to precipitate from the wastewater. Compared to a simple chemical reaction, using iron powder as a precipitant can increase the reaction rate and help obtain copper-containing precipitates with higher purity.
[0070] The above are merely preferred embodiments of this application and are not intended to limit the present invention. Although the present application has been described in detail with reference to examples, those skilled in the art can still modify the technical solutions described in the foregoing examples or make equivalent substitutions for some of the technical features. However, any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
