Technical Field

[0001] The utility model relates to the technical field of feeding of metallurgical equipment, in particular to a feeding device for a submerged arc furnace. Background Art

[0002] A submerged arc furnace is an industrial electric furnace that feeds materials intermittently. The raw materials in the submerged arc furnace are first transported to the rooftop bin, and then enter the furnace chamber of the submerged arc furnace by the self-gravity of the raw materials through the material pipe. The materials added into the submerged arc furnace through the material pipe will be stacked in a point shape inside the furnace chamber of the submerged arc furnace, forming a material pile. The materials cannot be evenly distributed in the furnace chamber of the submerged arc furnace for smelting, which affects the quality of the products smelted by the submerged arc furnace.

[0003] In view of the above technical problems, the utility model provides a feeding device for a submerged arc furnace, which is used to solve the problem that the submerged arc furnace is prone to material stacking when using a material pipe for feeding, resulting in uneven distribution of materials inside the furnace chamber of the submerged arc furnace.

[0004] In order to achieve the above purpose, the technical solution of the utility model is specifically as follows:

[0005] A feeding device for a submerged arc furnace includes a material distributing component, which is composed of a rib plate and a material distributing cylinder. The material distributing cylinder is in the shape of a frustum of a cone. A plurality of rib plates are provided and evenly distributed on the side wall of the material distributing cylinder. The free ends of the plurality of rib plates are connected to the discharge port of the material pipe.

[0006] Furthermore, it also includes a connecting component, which is composed of a material pipe, a connecting plate and a connecting flange. The connecting flange is arranged above the material pipe and is connected to the raw material discharging port. The discharge port of the material pipe is connected to the rib plate of the material distributing component through the connecting plate.

[0007] Furthermore, a cold water jacket is provided around the outer wall of the material pipe, and a water inlet pipe and a water outlet pipe are provided on the cold water jacket.

[0008] Compared with the prior art, the beneficial effects of the utility model are as follows: The structure of the utility model is simple, the installation is convenient, and the manufacturing cost is low. By installing this design at the furnace mouth position of the submerged arc furnace, the raw materials are shunted under the action of the material distributing component after passing through the material pipe, realizing staggered feeding, and solving the problem that the original material pipe is prone to material stacking; by arranging a cold water jacket around the outer wall of the material pipe, the cooling water enters the cold water jacket through the water inlet pipe, exchanges heat with the material pipe, and the cooling water after heat exchange is discharged through the water outlet pipe, avoiding the problem that the temperature of the material pipe is too high due to long-term operation at the furnace mouth of the submerged arc furnace.
