Description

Technical Field

[0001] This utility model relates to the field of copper foil wastewater technology, specifically to a wastewater treatment device. Background Technology

[0002] Wastewater is a significant environmental issue in copper foil production. Copper foil is primarily used in the manufacture of electronic products and batteries, generating substantial amounts of wastewater during production. This wastewater may contain various pollutants, such as heavy metals, acids, alkalis, and organic compounds. During copper foil production, the copper plate surface often undergoes acid leaching and pickling processes. The acid solutions used in these steps (such as sulfuric acid and chloride acids) react with the copper, dissolving it and forming copper ions (such as Cu). 2+ This process causes copper to enter the wastewater. Copper ions will remain in the wastewater as it is discharged.

[0003] Existing copper foil wastewater typically contains a large amount of magnetic metal materials. However, existing wastewater treatment devices generally filter out impurities from the wastewater, resulting in the waste of magnetic metal materials. This makes recycling difficult and hinders the effective utilization of impurities in the wastewater. Furthermore, after filtration by existing filters, a secondary screening of magnetic metal materials is required, making the process inconvenient. Utility Model Content

An extension plate 6 is fixedly connected to one side of the pretreatment tank 4.

[0023] A movable plate 7 is located inside the purification shell 1 on one side. The movable plate 7 facilitates the support of the magnetic suction plate 71, which in turn facilitates the adsorption of metal materials in the copper foil wastewater. The top of the movable plate 7 is fixedly connected to the magnetic suction plate 71. A guide plate 8 is fixedly connected to one side of the bottom of the inner cavity of the purification shell 1. A drive component 9 for cleaning the magnetic suction plate 71 is fixedly connected to one side of the extension plate 6. The drive component 9 includes a second motor 901 and a guide frame 902. A drain pipe 22 is installed on one side of the purification shell 1 through a solenoid valve.

[0024] Both sides of the interior of the purification shell 1 are fixedly connected to baffles 10. The baffles 10 facilitate the limiting installation of the filter plates 11. The filter plates 11 are arranged between the two baffles 10. A filter bag 12 for storing purification materials is fixedly connected to one side of the filter plates 11. The filter plates 11 and filter bags 12 are used to store activated carbon and other wastewater purification media, thereby improving the purification effect of wastewater. A cover plate 13 is fixedly connected between the tops of the two filter plates 11. The cover plate 13 is installed with the pretreatment box 4 by screws, which facilitates the disassembly and assembly of the filter plates 11. A first motor 14 is fixedly connected to the top of the pretreatment tank 4. The output end of the first motor 14 extends into the interior of the pretreatment tank 4 and is fixedly connected to a stirring rod 15. By turning on the first motor 14, the stirring rod 15 can be rotated, thereby stirring and mixing the wastewater in the pretreatment tank 4 with the purifying agent, such as flocculant. A feed pipe 16 is provided on one side of the top of the pretreatment tank 4, through which the purifying medium can be poured in to mix with the stirring rod 15. A water inlet pipe 17 is provided on one side of the pretreatment tank 4, through which wastewater can be poured into the interior of the pretreatment tank 4.

[0025] A scraper 18 is fixedly connected to one side inside the purification shell 1. The scraper 18 facilitates scraping off the metal material on the surface of the magnetic suction plate 71. A discharge shell 19 is provided on one side of the bottom of the purification shell 1. The discharge shell 19, together with the guide plate 8, can guide and discharge the scraped metal material. Sliding rings 20 are fixedly connected to the front and rear sides of the top of the magnetic suction plate 71. The sliding rings 20 and the sliding rods 21 can improve the stability of the magnetic suction plate 71 when it moves. The sliding rings 20 are provided with sliding rods 21 inside. The two ends of the sliding rods 21 are fixedly connected to the purification shell 1 and the guide plate 8, respectively.

[0026] The second motor 901 is fixed to one side of the extension plate 6. The output end of the second motor 901 is fixedly connected to the lead screw 903. One side of the lead screw 903 is rotatably connected to the support plate 904. One side of the support plate 904 is fixedly connected to the extension plate 6. By turning on the second motor 901, the lead screw 903 can be rotated. At this time, the threaded sleeve 905 will drive the guide frame 902 to move. As the guide frame 902 moves, it will drive the movable plate 7 to move the magnetic suction plate 71. Then, in conjunction with the scraper 18, the metal material adsorbed on the surface of the magnetic suction plate 71 is scraped off and collected. The surface of the lead screw 903 is fitted with the threaded sleeve 905. The surface of the threaded sleeve 905 is fixedly connected to the guide frame 902. One side of the guide frame 902 is fixedly connected to the movable plate 7.

[0027] Working principle: First, wastewater is introduced into the pretreatment tank 4 through the inlet pipe 17. Then, the purification liquid is poured in through the feed pipe 16. Immediately afterward, the first motor 14 is turned on to rotate the stirring rod 15, which stirs the wastewater and purification agent, such as flocculant. Then, the valve on the surface of the delivery pipe 5 is opened to discharge the wastewater into the purification shell 1. At this time, the water flows to the top of the magnetic suction plate 71 on the top of the movable plate 7. The magnetic suction plate 71 adsorbs the metal material in the copper foil wastewater. Then, the wastewater passes through the two filter plates 11 and the activated carbon material inside the filter bag 12. After filtration, the material is discharged through drain pipe 22. When the user needs to collect the adsorbed metal material, the second motor 901 is turned on, which makes the lead screw 903 rotate. At this time, the threaded sleeve 905 will drive the guide frame 902 to move. As the guide frame 902 moves, it will drive the movable plate 7 to move the magnetic suction plate 71. When the magnetic suction plate 71 moves, it will drive the sliding ring 20 to move in a limited position on the surface of the slide rod 21. Then, in conjunction with the scraper 18, the metal material adsorbed on the surface of the magnetic suction plate 71 is scraped off and discharged through the discharge shell 19 for collection.
