[0015] The utility model is described in detail below with reference to the accompanying drawings:
[0016] like Figure 1 and 2As shown, a nickel smelting slag sulfide reduction device comprises a nickel smelting furnace 1, which is an existing conventional nickel smelting furnace. The side wall of the nickel smelting furnace 1 is provided with a slag discharge port 2, and the slag during nickel smelting can be discharged from the nickel smelting furnace 1 through the slag discharge port 2. The slag discharge port 2 is provided with an inclined chute 3, and the chute 3 forms an angle of 30-60 degrees with the horizontal plane. In this embodiment, it forms an angle of 35 degrees with the horizontal plane. A barrel 4 for storing a reducing agent is provided above the chute 3, and a discharge pipe 5 is connected to the bottom of the barrel 4. A discharge valve 10 is provided on the discharge pipe 5. The reducing agent stored in the barrel 4 can be discharged through the discharge pipe 5, for example, to facilitate the discharge of all the reducing agents in the barrel 4. The lower part of the barrel is a conical structure with a large top and a small bottom, and the bottom end of the discharge pipe 5 is provided with a The discharging chute 6 is arranged at an inclination, and the discharging chute 6 forms an angle of 30-60 degrees with the horizontal plane. The discharging chute 6 is located above the chute 3 and corresponds to the chute 3. The material discharged from the discharge pipe 5 can be discharged into the chute 3 through the discharging chute 6. A vibration motor 7 is provided at the bottom end of the square material chute 6. When the reducing agent moves in the chute 3, the reducing agent can be evenly dispersed in the square material chute 6 through the vibration motor 7, and then the reducing agent is evenly sprinkled on the slag sliding down in the chute 3 through the discharging chute 6. A ladle 8 is provided at the bottom end of the chute 3. The slag discharged from the slag discharge port 2 can be transported to the ladle 8 through the chute 3. A spray gun 9 for spraying fire into the ladle 8 is provided on one side of the ladle 8. The slag in the ladle 8 can be heated by the spray gun 9 so that the slag is reduced by the reducing agent.
[0017] The usage of the utility model is as follows:
[0018] During nickel smelting, the molten filter residue produced during the nickel smelting process is discharged from the nickel smelting furnace 1 through the slag discharge port 2. The molten filter residue slides into the ladle 8 through the chute 3. The molten filter residue has a high temperature and consumes less energy for heating during reduction. It also has good fluidity and is easy to transport. During the process of the filter residue sliding in the chute 3, the discharge valve 10 is opened to allow the reducing agent in the barrel 4 to be discharged into the discharge chute 6 through the discharge pipe 5. In this embodiment, coal is used as the reducing agent. In order to improve the reduction effect, a sulfiding agent, such as sulfur powder, can also be added to the reducing agent, which is discharged into the chute 3 through the discharge chute 6. At the same time, the vibration motor 7 is turned on to pass the vibration motor 7. The vibrated reducing agent is evenly dispersed in the square material chute 6, and then the reducing agent is evenly sprinkled on the slag sliding down in the chute 3 through the discharge chute 6, so that the slag and the reducing agent are fully in contact, and then the slag mixed with the reducing agent enters the ladle 8 through the chute 3, and finally the slag temperature is increased by spraying fire into the ladle 8 through the spray gun 9, and then the slag is reduced to obtain nickel sulfide after reduction. Since the slag is evenly mixed with the reducing agent before entering the ladle 8, there is no need to stir it after entering the ladle 8. The reduction of nickel smelting slag using this device is efficient and fast, saving time and effort.
