Description
Technical field
The utility model relates to the ore smelting furnace, particularly a kind of charging opening refrigerating unit of producing the ore smelting furnace of basalt continuous fiber.
Background technology
Basalt continuous fiber is to adopt the natural basalt ore to draw after powder essence, fusing to form, basalt continuous fiber has unique high temperature resistant, corrosion-resistant, insulation thermal insulation and sound absorption qualities etc. because of it, be subjected to the extensive attention of countries in the world, can be widely used in fields such as Aeronautics and Astronautics, building, metallurgy, chemical industry.
Be fit to draw the natural basalt composition of ores complexity of basalt continuous fiber, be difficult to fusing, fusing back viscosity is big, therefore, the melter designs complexity of fused basalt ore, structure is special, costs an arm and a leg.This ore smelting furnace adopts Sweet natural gas to make thermal source fusing ore mostly, and its body of heater is built by laying bricks or stones with refractory brick and formed, and charging opening is arranged on the body of heater top, adopts the reinforced mode of open type.Find in the production use that the dome brick charging opening washes away down for a long time high-temperature flue gas, periphery is ablated quite serious, and the charging opening brick is short work-ing life, generally just must blowing out change about three months, and the stove brick at other position work-ing life then can be more than 1 year.So just influenced the whole service life of ore smelting furnace; even more serious is; a large amount of top filling brick refractory materialss of ablating enter in the feed liquid, have had a strong impact on the stability of wire-drawing operation, are unfavorable for long-term large-scale production operation and control, reduce production costs.
The utility model content
Technical problem to be solved in the utility model provides a kind of ore smelting furnace charging opening refrigerating unit, can control dome brick charging opening ablation phenomen effectively by this device, thereby help improving the quality of production of basalt continuous fiber, and prolong the whole service life of ore smelting furnace.
The technical scheme that its technical problem that solves the utility model adopts is: ore smelting furnace charging opening refrigerating unit of the present utility model, it is characterized in that it comprises: chuck, its outer wall and charging opening perisporium closely cooperate, and have internal cavities and add the intravital reinforced passage of stove for ore; Cooling medium circulation system is by inlet pipe, go out pipe and be connected with internal cavities.
After taking abovementioned technology, supply with heat-eliminating medium by the chuck circulation of cooling medium circulation system on the charging opening that is installed in ore smelting furnace dome brick, make chuck be in the lesser temps state for a long time, because the charging opening perisporium of chuck outer wall and dome brick closely cooperates, therefore can avoid the dome brick charging opening to be ablated effectively by high-temperature flue gas.
As a kind of preferred version of the present utility model, be to improve cooling performance, and avoid the chuck bottom not burnt out the charging opening of dome brick, prolong the work-ing life of chuck, described inlet pipe, go out the top that pipe is arranged on chuck; Be provided with at least one baffle plate in the described internal cavities, baffle plate only leaves the passage that its cavity that is separated out is connected in the bottom of internal cavities.The setting of baffle plate makes the heat-eliminating medium that enters in the internal cavities flow from the chuck bottom, can effectively the temperature of chuck bottom be controlled within the specific limits.
The beneficial effects of the utility model are, can control the charging opening ablation phenomen effectively, prolong the work-ing life of charging opening dome brick and ore smelting furnace integral body, reduce production costs; Can reduce refractory materials in a large number and enter the influence of feed liquid, therefore help improving the quality of production of basalt continuous fiber wire-drawing operation.
