[0002] In modern industrial systems, copper is widely used in many key fields such as power, electronics, construction, and machinery manufacturing due to its excellent electrical and thermal conductivity, good plasticity, and corrosion resistance. From high-voltage transmission lines and precision electronic components to building water supply and drainage pipes and parts for high-end machinery, copper plays an indispensable role. However, with the continuous expansion of industrial production scale and the accelerated pace of product upgrades, the amount of waste copper generated is increasing daily. According to relevant industry statistics, in the power industry alone, hundreds of thousands of tons of waste copper cables are generated annually due to line renovations and equipment upgrades. Effectively recycling and refining this waste copper can not only alleviate the pressure of copper resource shortages and reduce enterprises' dependence on primary copper mines, but also significantly reduce environmental pollution caused by copper mining and smelting, thus yielding both economic and environmental benefits.
[0003] When heat-refining waste copper, workers typically operate the equipment manually to feed, unload, and refine the material. This process is inefficient and poses safety hazards such as burns to the operators.
[0004] To address the aforementioned problems, we propose a purification device for the recycling of waste copper. Utility Model Content

[0015] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.
[0016] Example 1: Please refer to Figure 1 - Figure 3 This embodiment of a waste copper recycling purification device includes a base 1 and an induction furnace 2. A spiral feeding mechanism 3 is fixedly connected to one end of the top of the base 1. A side plate 11 is fixedly connected to the top of the base 1. A first servo motor 7 is provided on one side of the side plate 11. A transmission mechanism 8 is driven to one end of the first servo motor 7. Multiple rollers 9 are driven to the transmission mechanism 8. A mold 10 is provided on the top of the rollers 9. A top plate 12 is fixedly connected to the top of the side plate 11. Two vertical plates 13 are fixedly connected to the top of the top plate 12. The induction furnace 2 is rotatably connected to the inside of the vertical plates 13. A second servo motor 14 is provided on one side of the vertical plates 13. A small gear 15 is fixedly connected to one end of the second servo motor 14. A large gear 16 is meshed to one end of the small gear 15. A rotating shaft 17 is fixedly connected to one side of the large gear 16. One end of the rotating shaft 17 is fixedly connected to the outside of the induction furnace 2. Among them, the existing induction furnace 2 generally utilizes the principle of electromagnetic induction to generate an alternating magnetic field through a coil, causing the metal inside the furnace to heat up and melt. It has high thermal efficiency, fast heating speed, precise temperature control, and can reduce metal oxidation loss. Secondly, the scrap copper is usually crushed first, and then the crushed pieces are conveyed to the induction furnace 2 through the spiral feeding mechanism 3. The induction furnace 2 melts the scrap copper. After the melting is completed, the first servo motor 7 is started, which drives the roller 9 to rotate through the transmission mechanism 8, so that the mold 10 moves to the designated receiving position. Since the side plate 11 is equipped with a photoelectric sensor, when the mold 10 moves to the designated receiving position directly below the discharge port of the induction furnace 2, the sensor triggers a signal to the control system, and the first servo motor 7 immediately stops running to ensure that the mold 10 is accurately positioned. Then the second servo motor 14 is started, driving the pinion 15 to rotate. The pinion 15 meshes with and drives the large gear 16 to rotate, which in turn drives the induction furnace 2 to tilt through the rotating shaft 17, pouring the molten copper into the mold 10 for collection. After collection, the first servo motor 7 is started again to transfer the mold 10 filled with molten copper to the next process, while a new empty mold 10 is moved to the bottom of the discharge end of the induction furnace 2 to wait. Furthermore, a support column 4 is fixedly connected to the other end of the top of the base 1, and a feeding hopper 5 is fixedly connected to the top of the support column 4. One end of the spiral feeding mechanism 3 is located at the top of the feeding hopper 5, and the feeding hopper 5 is located at the top of the induction furnace 2. The feeding hopper 5 can collect the waste copper fragments conveyed by the spiral feeding mechanism 3 and guide them to fall accurately into the induction furnace 2, thereby improving the continuity and stability of the feeding. Furthermore, the screw feeding mechanism 3 includes a feed inlet 301 and a discharge outlet 302. The feed inlet 301 is located on the bottom side of the screw feeding mechanism 3, and the discharge outlet 302 is located on the top of the feed hopper 5. A stepper motor 6 is provided at one end of the top of the screw feeding mechanism 3. A screw shaft 303 is fixedly connected to one end of the stepper motor 6. A propeller 304 is fixedly connected to the outside of the screw shaft 303. The propeller 304 is movably connected inside the screw feeding mechanism 3. In this process, waste copper scraps are fed into the feed inlet 301, and then the stepper motor 6 is started. The stepper motor 6 drives the spiral shaft 303 to rotate, and the spiral shaft 303 drives the propeller 304 to rotate, thereby conveying the waste copper scraps to the top of the spiral feeding mechanism 3 and feeding them into the induction furnace 2 for processing through the discharge port 302. Furthermore, the transmission mechanism 8 includes a drive wheel 801 and a synchronous belt 802. One end of the first servo motor 7 is fixedly connected to the drive wheel 801. The outside of the drive wheel 801 is connected to one end of the synchronous belt 802. The inside of the synchronous belt 802 is connected to multiple transmission wheels 803. One end of each transmission wheel 803 is fixedly connected to multiple rollers 9. The rollers 9 are rotatably connected between the two side plates 11. Specifically, by activating the first servo motor 7, the first servo motor 7 will drive the drive wheel 801 to rotate, the drive wheel 801 will drive the synchronous belt 802 to rotate, the synchronous belt 802 will drive multiple transmission wheels 803 to rotate, and the transmission wheels 803 will drive the roller 9 to rotate, thereby driving the mold 10 on the top of the roller 9 to move forward.
[0017] Working principle: The scrap copper is conveyed to the induction furnace 2 through the screw feeding mechanism 3. The induction furnace 2 melts the scrap copper. After melting, the first servo motor 7 is started to move the mold 10 to the designated receiving position. Then the second servo motor 14 is started to drive the pinion 15 to rotate the large gear 16, which in turn causes the induction furnace 2 to tilt and pour the molten copper into the mold 10 for collection. After collection, the first servo motor 7 is started again to transfer the mold 10 filled with molten copper to the next process. At the same time, a new empty mold 10 is moved to the bottom of the discharge end of the induction furnace 2 to wait.
