The invention discloses a self-sintering device of a submerged arc furnace, and relates to the technical field of mining and metallurgy equipment. The self-sintering device comprises a sintering device lifting device mounted on a self-sintering device mounting platform, a sintering cylinder held by the sintering device lifting device and a sintering device feeding device arranged at the upper partof the sintering cylinder, the sintering device feeding device comprises a screw feeder and a negative pressure pipe arranged in the sintering cylinder; through holes are formed in the wall of the negative pressure pipe, and the top end of the negative pressure pipe is connected with a negative pressure induced draft fan; an extrusion head is arranged in the sintering cylinder and connected withone end of a feeding hydraulic cylinder through a downward pressing circular ring, and the other end of the feeding hydraulic cylinder is fixed to a supporting plate connected with the outer wall of the sintering cylinder; a material level sensor is arranged on the sintering cylinder above the extrusion head, and a temperature sensor is arranged at the lower section of the sintering cylinder. According to the self-sintering device of the submerged arc furnace, the problems that when a traditional submerged arc furnace is used for smelting red mud, feeding is difficult, energy consumption is large, and the water burst phenomenon is likely to be generated due to high water content can be solved.
Description
technical field [0001] The invention relates to the technical field of mining and metallurgy equipment, in particular to a self-sintering device for smelting red mud charge in a submerged arc furnace. Background technique [0002] Red mud is the residue formed after alumina is extracted from bauxite. The residue is rich in chemical components such as ferric oxide, silicon dioxide, aluminum oxide, calcium oxide and sodium oxide. At present, only a very small part of the red mud in the world is comprehensively utilized, and most of it is still sent to the yard for open storage, which not only occupies a lot of land, but also costs a lot of money, and it is easy for a large amount of waste lye to infiltrate the nearby farmland. Cause soil alkalization, swamp, pollute surface and underground water sources, endanger the environment and human health. [0003] Due to the high moisture content of red mud (more than 30%), it is a high-moisture micro-powder muddy mineral, and the mud...
