Ore smelting furnace charging opening refrigerating unit
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.

Embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
With reference to Fig. 1, ore smelting furnace charging opening refrigerating unit of the present utility model, it comprises: chuck 20, its outer wall and charging opening 11 perisporiums closely cooperate, and have the reinforced passage 24 in internal cavities 21 and the confession ore adding body of heater 10; Cooling medium circulation system 30 is by inlet pipe 22, go out pipe 23 and be connected with internal cavities 21.Supply with heat-eliminating medium by chuck 20 circulations of cooling medium circulation system 30 on the charging opening 11 that is installed in ore smelting furnace dome brick 10, make chuck 20 be in the lesser temps state for a long time, because chuck 20 outer walls and charging opening 11 perisporiums closely cooperate, therefore can avoid charging opening 11 to be ablated effectively by high-temperature flue gas.
On the basis of abovementioned technology, for improving cooling performance to the charging opening of dome brick, and avoid chuck 20 bottoms not burnt out, prolong the work-ing life of chuck, with reference to Fig. 1, described inlet pipe 22, go out the top that pipe 23 is arranged on chuck 20, be provided with at least one baffle plate 25 in the described internal cavities 21, baffle plate 25 only leaves the passage 26 that its cavity that is separated out is connected in the bottom of internal cavities 21.The setting of baffle plate 25 makes the heat-eliminating medium that enters in the internal cavities 21 flow from chuck 20 bottoms, can effectively the temperature of chuck 20 bottoms be controlled within the specific limits.
Fig. 2, Fig. 3 and Fig. 5 show a kind of concrete structure of chuck 20.With reference to Fig. 2, described chuck 20 comprises by extending and concentric outer shroud 20a, interior ring 20b along charging opening 11 axis, and thereon, be attached thereto last annular plate 20c, time annular plate 20d that forms one on the lower port.With reference to Fig. 3, described baffle plate 25 is connected with outer shroud 20a, interior ring 20b and last annular plate 20c, and the gap that exists between the lower end of baffle plate 25 and the following annular plate 20d forms passage 26.With reference to Fig. 3 and Fig. 4, as a kind of optimal way, the quantity of described baffle plate 25 is two, promptly along circumferential uniform baffle plate 25a, the 25b of outer shroud 20a, interior ring 20b.
In actual production, outer shroud 20a, interior ring 20b, last annular plate 20c, following annular plate 20d baffle plate 25a, 25b etc. preferably adopt the high temperature resistant stainless steel plate more than the thickness 3mm to make, and want firm welding.It is too many that chuck 20 should not stretch into charging opening 11, and its distance from bottom furnace roof brick 10 bottom 15mm are advisable, and chuck 20 outer walls must closely cooperate with the perisporium of charging opening 11.Heat-eliminating medium should preferably adopt water coolant, and temperature of cooling water should not be above 80 ℃.
Some principles of the above the utility model ore smelting furnace charging opening refrigerating unit that just explains through diagrams, be not be the utility model ore smelting furnace charging opening refrigerating unit to be confined to shown in and in described concrete structure and the scope of application, so every the corresponding modify and equivalent that might be utilized all belongs to the claim that the utility model is applied for.
