Abstract

The invention discloses a macrocrystalline fused magnesite smelting furnace and particularly relates to a fused magnesite smelting furnace with a filling device. A fused magnesite smelting furnace body comprises a furnace body, electrodes and a rail platform, wherein stock bins are arranged on two sides above the furnace body; thermal conductive plates are arranged in the stock bins; material distribution pipes are mounted in sleeves in a sleeving manner. The working method of the fused magnesite smelting furnace is as follows: powder is scattered in the furnace body through the material distribution pipes to realize automatic filling. Leaking holes in the thermal conductive plates enable powder in the stock bins to complement each other, so that material in each stock bin grid is enabled to be uniform. As the stock bins are arranged above the furnace mouth, and high-temperature smoke discharged from the furnace mouth heats the shells of the stock bins, the raw material in the stock bins is heated; therefore, the raw material with a certain temperature enters the furnace body, the smelting time is shortened, and the consumption of electric energy is reduced. As the stock bins are arranged, the labor intensity of workers is greatly reduced, and potential safety hazards during operation are eliminated. In addition, as the raw material is distributed uniformly, the raw material reduction is more sufficient, the quality of the finished product is improved, and the problems of the existing equipment are solved.

Description

technical field [0001] The invention discloses a large crystal fused magnesia smelting furnace, specifically an fused magnesia smelting furnace with a filling device. Background technique [0002] The large crystal fused magnesia smelting furnace currently used in production is only composed of a cylindrical furnace body and electrodes located on an orbital platform. In the production, the electrodes are placed first, and then the powder is added into the furnace cavity for smelting after the arc is started. During operation, workers stand on the operating platform above the furnace body and use simple tools to fill and distribute materials in the furnace. Since the furnace mouth is open, the temperature of the flue gas overflowing from the furnace mouth is 50-800 degrees Celsius, permeating the workshop, in vain. The ground loses a lot of heat energy. During production, raw materials are stacked near the furnace mouth, and workers need to operate at close range. In this ...
