Description

Technical Field

[0001] The invention belongs to the technical field of industrial ferrosilicon ore smelting equipment, and in particular relates to an automatic material distribution device and a material distribution method for closed industrial ferrosilicon ore smelting. Background Art

[0002] In the smelting process of domestic silicon-based ore-fired furnaces, 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 the 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 discloses an automatic pitching and rotating feeding device for an electric furnace, comprising an electric furnace, a smoke hood is provided on the periphery of the feeding 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, the output shaft of the reduction motor is transmission-connected with the outer ring of the slewing bearing, and is used to drive 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, and is used to drive the chute to achieve pitching action. 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 device achieves uniform distribution of materials and consistent thickness through automatic rotation and pitching of the chute. However, in actual use, different pitch angles of the chute will cause 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 and material distribution method for closed industrial ferrosilicon ore smelting to solve the above-mentioned problems. Summary of the invention

10. A method for distributing material for a ferrosilicon ore furnace, characterized in that: The material distribution method of the automatic material distribution device for closed industrial ferrosilicon ore smelting according to any one of claims 1 to 9 specifically comprises the following steps: S1: adjusting the pitch angle of the material distribution hopper (300) by starting the adjustment motor (702); S2: driving the feeding cylinder (200) to rotate by rotating the motor (602), thereby driving the material distribution hopper (300) to rotate around the feeding cylinder (200); S3: The raw materials are added through the storage hopper (100), and then the raw materials enter the inside of the charging barrel (200) along the inner lower hopper (405) and the outer lower hopper (406), and then distributed in the smelting furnace in a spiral shape along the distribution hopper (300); S4: By starting the electric push rod (407) to drive the sliding frame (403) to slide in the first slide groove plate (402), the inclination angles of the inner lower hopper (405) and the outer lower hopper (406) can be changed according to the pitch angle of the distribution hopper (300), so that the falling speed of the raw materials in the distribution hopper (300) can be kept uniform, so that the raw materials are distributed more evenly in the smelting furnace. S5: By starting the moving motor (504) to drive the screw (503) to rotate, the moving frame (401) can move in the opposite direction along the two fixed frames (501) and the connecting cylinder (404), thereby keeping the connecting cylinder (404) relatively still, ensuring that the connecting cylinder (404) is facing the feeding cylinder (200).
