[0002] The bottom-blown furnace is a mainstream device widely used in the lead smelting industry. The feeding and sealing device at the feeding port of the bottom-blown furnace body mainly consists of two fixed upper hoppers and a lower hopper. The lower hopper is fixedly connected to the furnace body, and the upper hopper is fixedly connected to the manual operation platform.

[0003] However, in order not to interfere with the rotation of the furnace body, a large gap is left between the upper and lower hoppers. Defects generated during feeding in this gap are likely to cause material leakage. Since the leaked material is not easy to collect, this will not only cause a large waste of resources, but also pose potential safety and environmental protection hazards in the material leakage phenomenon.

[0004] Therefore, a feeding device for a bottom-blown furnace is needed to solve the problem of material leakage caused by the defects of the feeding hopper of the bottom-blown furnace in the prior art. Summary of the Utility Model

Specific embodiments

[0023] The following further describes the present utility model in conjunction with embodiments.

[0024] Please refer to Figures 1-4 , the present utility model provides a feeding device for a bottom-blown converter, including a lower hopper 1 and an upper hopper 3. The upper hopper 3 is arranged directly above the lower hopper 1. A first docking bevel 5 is provided at the upper end of the lower hopper 1, and a second docking bevel 6 is provided at the lower end of the upper hopper 3. An automatic inner lining mechanism is arranged inside the upper hopper 3.

[0027] This solution has the following working process: Before use, the lower end plate 2 part of the lower hopper 1 is fixed to the furnace body, and the upper end plate 4 part of the upper hopper 3 is fixed to the manual operation platform. During use, the first docking bevel 5 of the lower hopper 1 can be meshed and docked with the second docking bevel 6 of the upper hopper 3, so as to ensure the docking of the lower hopper 1 and the upper hopper 3 when the bottom-blown converter is in the upright state and effectively reduce material leakage while not affecting the tilting of the bottom-blown converter.

[0028] According to the above working process, it can be known that the first docking bevel 5 of the lower hopper 1 can be meshed and docked with the second docking bevel 6 of the upper hopper 3, so as to ensure the docking of the lower hopper 1 and the upper hopper 3 in the correct position of the bottom-blown converter while not affecting the tilting of the bottom-blown converter, and effectively reduce material leakage.

[0029] Furthermore, as shown in Figure 1 , Figure 2 and Figure 4 it is worth specifically stating that a lifting bracket 9 is arranged between the lifting cylinder 10 and the guiding sliding sleeve 7. One end of the lifting bracket 9 is fixed to the output end of the lifting cylinder 10, and the end of the lifting bracket 9 far from the output end of the lifting cylinder 10 is fixed to the upper end face of the guiding sliding sleeve 7. When the lower hopper 1 is docked with the upper hopper 3, the inner lining cone sleeve 8 at the lower end of the guiding sliding sleeve 7 extends into the inner cavity of the lower hopper 1. At the same time, the sealing rubber sleeve 12 is closely attached to the docking seam between the first docking bevel 5 and the second docking bevel 6 to achieve a sealing effect, which can reduce the trouble of material accumulation at the docking seam between the first docking bevel 5 and the second docking bevel 6, thereby preventing the accumulated material from spilling out when the docking bevel opens during the tilting of the furnace body. Before the furnace body tilts, the lifting cylinder 10 is started, and the output end of the lifting cylinder 10 drives the guiding sliding sleeve 7 and the inner lining cone sleeve 8 to rise, providing conditions for the misalignment separation of the lower hopper 1 and the upper hopper 3.
