Description

Technical Field

[0001] The utility model relates to the technical field of fused magnesia production equipment, in particular to a device for evenly regulating the distribution of large-crystallization fused magnesia furnaces. Background Art

[0002] Large crystal fused magnesia is mainly made by melting light-burned magnesium oxide powder in a submerged arc furnace. It has many advantages such as high purity, large crystal grains, dense structure, strong slag resistance, good thermal shock stability, etc. It is an important raw material for the production of high-grade magnesia bricks, magnesia carbon bricks and amorphous refractory materials. At present, the submerged arc furnace is mainly composed of a furnace drum, a graphite electrode and a rail car. The furnace drum is generally a cylinder with a diameter of 1.3 to 2.0m and a height of 4 to 6m, which is welded with a steel plate roll with a thickness of 5 to 8mm. The furnace drum is placed on the rail car, and three graphite electrodes are extended into the interior of the upper opening of the furnace drum. The material distribution method adopts manual shoveling or high-level silo. The charge is poured from one or two points on the upper part of the furnace to the bottom of the furnace, and current is introduced through the graphite electrodes to heat and melt the charge between the electrodes. During the production process, as the charge is continuously added, the electric control system automatically controls the electrodes to gradually rise until the molten charge fills the furnace tube and finally completes a smelting cycle. After the smelting is completed, the graphite electrodes are completely pulled out, and the furnace tube is pushed to the factory building by a rail car for natural cooling. Usually, the furnace tube is replaced for each furnace, and the graphite electrodes and rail cars can be recycled. The disadvantages of the existing technology are: in the method of manual shoveling and spreading, the charge is first transported to the operating platform above the furnace tube, and the workers use The charge is shoveled into the furnace barrel with tools such as shovels, and the charge falls from the upper opening of the furnace barrel to the bottom of the furnace barrel. The labor intensity of the workers is extremely high, and during the continuous smelting process of the ore-heat furnace, the temperature of the operating platform is extremely high. The dust bursting upward from the furnace barrel during the shoveling process causes serious pollution and seriously damages the health of the workers. During smelting, high-pressure gas in the charge often sprays upward, causing furnace spraying and splashing accidents, which seriously threaten the personal safety of the workers. In addition, this method also has the problem of uneven charge distribution. In the high-level silo chute distribution method, a chute is used to slide the charge into the furnace barrel. During the distribution process, manual intervention can be made to adjust the discharge direction, but there is still a problem. The problem of uneven charge distribution is that during the charge distribution process, the charge accumulates in a fixed place or several places. As the charge falls, most of the charge can be spread on the bottom of the furnace, but there is still a charge peak directly below the charging position, which causes the charge to be not evenly spread on the bottom of the furnace tube of the ore-fired furnace. During the electric smelting process, a large amount of gas will be generated when the charge is melted. Uneven charge and too thick a layer of charge or poor air permeability of the layer of charge will cause gas to gather in the smelting area of ​​the charge, and then the air pressure will increase, causing production accidents such as furnace spraying and furnace splashing and personal safety accidents. Therefore, a large-crystal electric fused magnesia furnace uniformly adjusts the charge distribution device to solve the above problems. Utility Model Content
