Problems solved by technology

However, the inner end of the electrode may be damaged during use, resulting in a decrease in the electrothermal efficiency between the electrodes and a decrease in the production efficiency of the submerged arc furnace.
[0006] In addition, at present, the electrodes installed vertically in the submerged arc furnace tend to form a kiln in the middle of the electrode in the furnace body. At this time, workers need to use the rod body to break the kiln. accident, poor safety

Abstract

The invention provides a safe and efficient submerged arc furnace electrode adjustable structure. The structure comprises a furnace body, electrodes are distributed on the side wall of the furnace body in a penetrating mode, and the electrodes are arranged in the furnace body in a telescopic moving mode through a moving device. The moving device comprises a guide rail, a clamp holder, an insulating support and a chassis, the chassis is arranged on the guide rail and moves back and forth along the guide rail, the insulating support is fixed on the chassis, and the clamp holder is fixedly connected to the insulating support; a clamping hole is formed in the top of the clamping device, a clamping plate capable of being opened and closed is arranged on the upper portion of the clamping hole, the outer end of the electrode is fixedly sleeved with the clamping hole, and the guide rail and the electrode are the same in axial direction. The electrodes on the side walls of the furnace body aretelescopic, so that the distance between the electrodes on the two side walls can be adjusted, and the stability of the production efficiency is ensured; the submerged arc electric heating moving device is scientific and reasonable in design, high in electrode utilization rate, high in submerged arc electric heating controllability in the submerged arc furnace, stable in working state, capable ofachieving a damping function and convenient to operate.

Description

technical field [0001] The invention relates to the technical field of submerged arc furnaces, in particular to an electrode adjustable structure of a safe and efficient submerged arc furnace. Background technique [0002] The submerged arc furnace is the main equipment for the production of electrochemical products. It mainly heats the materials in the furnace (such as quicklime and carbon materials) through the submerged arc electric heating of the electrodes and the resistance electric heating of the materials, so that the materials undergo chemical reactions to produce electrochemical products. Finished products (such as calcium carbide or ferroalloys). [0003] The Chinese invention patent with the notification number CN206783327U discloses a system for producing calcium carbide, including a lime kiln, a semi-coke drying device, a mixing bin and a submerged arc furnace. The submerged arc furnace includes a furnace body and three vertically inserted furnace bodies. Phas...
