[0002] Non-ferrous metals are a general term for all metals other than ferrous metals, which consist of iron, manganese, and chromium. Copper, one of the earliest non-ferrous metals used by humans, possesses unique properties such as corrosion resistance, wear resistance, electrical conductivity, thermal conductivity, toughness, and plasticity.

[0024] The driving member 12 includes a driving motor 24 fixedly mounted on the base 1. The model of the driving motor 24 is preferably Y80M1-2. The output end of the driving motor 24 is coaxially fixedly connected to a driving shaft 25.

[0025] The rotating member 26 includes a first pulley 27 coaxially fixedly mounted on the drive shaft 25, a second pulley 28 rotatably connected to the base 1, a transmission belt 29 transmission-connected to the first pulley 27, a rotating shaft 30 coaxially fixedly connected to the second pulley 28, a driving gear 31 coaxially fixedly connected to the rotating shaft 30, an outer toothed ring 32 fixedly connected to the outer wall of the rotating cylinder 4, and the outer toothed ring 32 meshes with the driving gear 31.

[0026] A vent 35 is provided in the middle of the rotating disk 15, and an exhaust fan 36 is fixedly connected to the vent 35. An exhaust pipe 37 is fixedly connected to the inner wall of the fixed pipe 17. The bottom end of the exhaust pipe 37 is connected to the vent 35. A flue gas purification device 38 is provided in the exhaust pipe 37. The bottom end of the smelting furnace 2 is connected to an output pipe 39 and a slag discharge trough 40. Both the output pipe 39 and the slag discharge trough 40 can be controlled to open and close.

[0027] Working principle: The lump of copper smelting slag is loaded into the position between the feed hopper 33 and the guide hopper 34, and the slag falls downward into the gap between the first crushing teeth 19. The drive motor 24 is started to drive the drive shaft 25 to rotate, so that the first pulley 27 drives the transmission belt 29 to rotate the second pulley 28, and the second pulley 28 drives the rotating shaft 30 to rotate the driving gear 31, and the driving gear 31 drives the outer gear ring 32 to rotate the rotating drum 4, and the rotating drum 4 drives the first crushing teeth 19 and the rotating tube 18 to rotate. At this time, the first crushing teeth 19 will rotate in the direction of the upper end. The inclination direction of the first crushing teeth 19 is opposite to the inclination direction of the second crushing teeth 20. At this time, the first crushing teeth 19 drive the slag to rotate synchronously, and the bottom of the slag collides and rubs with the gap between the tips of the second crushing teeth 20 to crush the slag to the required size. The slag is transported downward through the gap between the second crushing teeth 20 to the position between the rotating drum 4 and the fixed drum 13 for storage.

[0028] Oxygen is introduced into the bottom end of the spiral tube 14, and the oxygen is transported in a spiral manner in the spiral tube 14. When the oxygen passes through the inclined baffle 22, the inner diameter of the pipe is reduced by the principle of the venturi tube, and the flow rate at the tip of the inclined baffle 22 is increased, thereby generating a suction effect on the adjacent connecting hole 21. The tip of the inclined baffle 22 is facing the direction of oxygen transport. At this time, the slag ash between the rotating cylinder 4 and the fixed cylinder 13 can be sucked into the spiral tube 14 for transport. At the same time, the heat of the smelting furnace 2 itself is used to heat the spiral tube 14. The oxygen and raw materials in the tube 14 are preheated. When the rotating cylinder 4 rotates, the multiple sets of fan plates 23 inside will be driven to rotate, which will help blow and stir the slag ash to ensure that it can be evenly pumped by the oxygen in the spiral tube 14. The oxygen is transported to the annular groove 16 at the top of the spiral tube 14, and then transported to the connecting tube 7 through the annular groove 16. It is discharged from the first side hole 10 on the side of the bottom end of the connecting tube 7 into the sleeve tube 8, and is discharged through the second side hole 11 on the side of the sleeve tube 8 to the smelting furnace 2 for smelting.

[0029] When the amount of raw material melted in the smelting furnace 2 continues to increase, the sleeve tube 8 will float up, and at the same time, the operation of the driving motor 24 will also drive the bottom plate 5 to rotate, and the bottom plate 5 will drive multiple groups of stirring rods 6 to rotate, and the stirring rods 6 will drive the connecting pipe 7 and the sleeve tube 8 to rotate synchronously, so that the rotating disk 15 will rotate. During the rotation of the rotating disk 15, the exhaust fan 36 can rotate to discharge the exhaust gas above from the exhaust pipe 37. The exhaust gas is discharged after being purified by the flue gas purification equipment 38. When the rotating disk 15 rotates, the annular groove 16 can always maintain a connected state with the top of the spiral tube 14. When the sleeve tube 8 floats up, since the density of the sleeve tube 8 is less than the density of the copper solution, the molten copper solution inside will float the sleeve tube 8 and keep the liquid The surface is located below the floating line 9, so that the output oxygen and slag ash can be directly discharged to a distance above the solution. At this time, the slag ash can be mixed with the molten liquid more quickly. Compared with the traditional method of transporting from the top, this transportation method can more quickly transport the slag ash to a position closer to the molten liquid for direct melting. The method of putting it in from the top will cause dust to be generated, making it difficult for a part of the slag ash to fall to the position where it contacts the molten liquid for melting, and it floats inside the smelting furnace 2 and cannot be evenly smelted and mixed. This method of transporting oxygen also enables oxygen to be continuously transported to a position close to the molten liquid for oxygen supply, avoiding the oxygen just input from being directly discharged with the exhaust gas, causing waste of resources.

[0030] The driving motor 24 drives the synchronous rotation of the rotating drum 4 and the stirring rod 6, thereby achieving the crushing of the slag and the stirring of the molten liquid, improving the smelting efficiency. At the same time, the slag ash is inputted along with the input of oxygen, which improves the internal melting efficiency and enables the input slag ash to be melted more quickly. The internal heat is used for preheating during the transportation process, and it can also assist in the insulation operation of the smelting furnace 2, making full use of the heat and reducing the waste of resources. When the molten liquid in the smelting furnace 2 floats the sleeve 8 to above the set height, the inner wall of the bottom end of the sleeve 8 will block the first side hole 10 during the upward movement, stopping the input of raw materials. At this time, the output pipe 39 is opened to discharge the molten liquid at the bottom, so that the liquid level is lowered, thereby causing the position of the sleeve 8 to move downward, gradually opening the first side hole 10, and the raw materials continue to be input. After closing the output pipe 39, the smelting operation continues, and the waste slag is subjected to a secondary smelting operation. After the smelting is completed, the driving motor 24 is turned off, the output pipe 39 is opened to discharge the bottom molten liquid, and then the impurities floating on the top are discharged through the slag discharge trough 40.
