Description

Technical Field

[0001] The utility model belongs to the technical field of industrial ferrosilicon ore smelting devices, in particular to an automatic material distribution device for closed industrial ferrosilicon ore smelting. Background Art

[0002] In the domestic silicon-based ore-fired furnace smelting process, semi-closed electric furnaces are generally used. During the smelting process, silica needs to rely on coke for reduction reaction. If the distribution is uneven, it will directly lead to uneven distribution of the reducing agent in the furnace, which will have a negative impact on the smelting efficiency. In addition, the uneven distribution will disrupt the normal distribution of current in the furnace, adversely affect the working state of the electrode, cause the temperature gradient in the furnace to be unbalanced, and cause the crucible volume to shrink, which will eventually lead to the deterioration of the furnace condition and affect the overall smelting effect. In this process, the existing raw materials are added intermittently, supplemented by manual operation to pound the furnace and push the materials, which not only increases the labor burden of the staff, but also makes it difficult to ensure the uniformity of the distribution.

[0003] In order to solve the above problems, in the existing public literature, CN212482118U an automatic pitching and rotating feeding device for an electric furnace is disclosed, which includes an electric furnace, a smoke hood is provided on the periphery of the feed port of the electric furnace, a hollow sealing seat is movably installed on the upper mouth of the smoke hood, a slewing bearing is fixed on the sealing seat, a connecting seat is fixed on the inner ring of the slewing bearing, a reduction motor is provided on one side of the connecting seat, and the output shaft of the reduction motor is connected to the outer ring of the slewing bearing for driving the sealing seat to rotate at a low speed at the upper mouth of the smoke hood; a U-shaped hinged seat is provided at the center below the sealing seat, and a chute is hinged on the hinged seat; an oil cylinder support is fixed on the sealing seat, and a hydraulic cylinder is hinged on the oil cylinder support, and the lower end of the piston rod of the hydraulic cylinder is inserted into the smoke hood through a connecting rod and is hinged to the upper end of the chute for driving the chute to achieve pitching movement. The device can realize automatic rotation and pitching of the chute to achieve uniform distribution and consistent thickness; it can avoid workers operating in front of the furnace, improve equipment safety, reduce workers' labor intensity and smelting power consumption, and improve labor efficiency.

[0004] The above-mentioned device achieves uniform distribution of materials and consistent thickness through the automatic rotation and pitching of the chute. However, in actual use, the different pitch angles of the chute will lead to different falling speeds of the raw materials. When the chute is tilted at a larger angle, the raw materials fall faster, which will cause the raw materials to be laid too thickly, and vice versa, the raw materials will be laid thinner.

[0005] To this end, we provide an automatic material distribution device for closed industrial ferrosilicon ore smelting to solve the above problems. Utility Model Content
