Distributing device and submerged arc furnace equipped with distributing device

Abstract

The invention relates to a submerged arc furnace with a distribution device. The submerged arc furnace comprises a furnace body, a fixing support arranged at the top of the furnace body and the distribution device; the distribution device comprises a universal rotating joint, a clamping joint, a feeding chute, an electric rotating mechanism and a hydraulic pressure jigging mechanism; as the distribution device is driven by a motor, the feeding chute for discharging mineral materials can perform the back-and-forth rotation in a horizontal plane, and the materials are scattered in a fan-shaped area in the furnace body along the feeding chute; as the distribution device is driven by a hydraulic cylinder, the lower end of the feeding chute for discharging the mineral materials can also be driven to vertically jig with a rotating shaft as a supporting shaft when a hydraulic cylinder head stretches out and draws back, and the materials are scattered along the diameter of the part, in the furnace body, of the chute; and dual drive in the manner is adopted, so that the materials are evenly scattered in the furnace body in a dispersed manner when passing through the feeding chute, a material smelting reaction is even, stable and thorough, and the product yield is more stable. The invention further provides the distribution device.

Description

technical field [0001] The invention relates to the technical field of submerged arc furnace metallurgy, in particular to a material distribution device and a submerged arc furnace provided with the material distribution device. Background technique [0002] The submerged arc furnace is a high energy-consuming equipment used to smelt ferroalloys and calcium carbide and other industrial primary products. When the submerged arc furnace smelts materials such as ores, the materials need to be sent into the furnace body first. In the prior art, the materials pass through three stages. A fixed material input pipe enters the interior of the furnace body. The on-site operator uses tools such as long picks to penetrate into the furnace body from the window of the furnace body, and pushes the materials so that the materials are evenly arranged in the furnace and the materials at various positions in the furnace of the same thickness. [0003] However, the above-mentioned operation me...

Problems solved by technology

[0003] However, the above-mentioned operation method has the following problems: due to the high internal temperature of the furnace body, it poses a great threat to the safety of the on-site operators who stir the materials in front of the furnace, and the efficiency of manually pushing the materials is low and the stability of the uniform distribution of the materials cannot be guaranteed.
