Technical scheme
A kind of high temperature solution drainage conduit mainly comprises the pipeline of the heavy water kinking structure of band that exotic material constitutes and intermediate frequency power supply coil two parts that are used to heat of duct wall winding outward.
The exotic material that constitutes duct wall can be selected in the materials such as zirconia, alundum (Al, magnesia, graphite, heat resisting steel, diamond spar of ability relevant temperature one or more for use according to the temperature of smelting.
The intermediate frequency power supply coil is wrapped in outside the duct wall of heavy water kinking structure.
Between the exotic material layer of formation duct wall and the intermediate frequency power supply coil high temperature resistant heat insulation layer is arranged.
The smelting furnace that has the high temperature solution drainage conduit; Charging aperture is arranged at furnace chamber top, and charging aperture is provided with the charging aperture valve, Waste gas outlet on the furnace wall and furnace chamber UNICOM; Be the intermediate frequency power supply coil outside the furnace wall, furnace bottom has the liquid of discharge gate and high temperature solution drainage conduit to flow into end tube chamber UNICOM.
High temperature solution in the utility model is meant when being higher than its fusing point and is molten condition, is solid-state material melt flow stream at high temperature when being lower than its fusing point.
Beneficial effect: utilize the high temperature solution drainage conduit no longer to adopt to topple over mode just can the liquation in the furnace chamber be discharged, thereby reduce the liquid of melting, the chance that the stove inwall contact with air, reduce the sunken trouble of safety.
With a high temperature melt discharge tube in the melting furnace, the elbow in the deposition of submerged liquid solidification closed nesting cavity, the inlet valve is closed, the oven cavity of raw materials can be isolated from the air in case, melting, smelting end need to discharge the molten furnace, only frequency power supply for discharge pipe coil is energized, the bent portion submerged again solidified melt material melted in the furnace can melt discharged to the designated location without air access Tong.
