Abstract
The utility model belongs to the metallurgical technology, particularly a smelting furnace. The utility model has the technical characteristic that the external wall circumference of the furnace body is provided with a spiral wind chamber, and heat pipes are arranged on the external wall of the furnace body along the wind chamber bottom evenly. Three air pipes are evenly distributed on the outer circumference of a furnace shell arranged out of the furnace body. The upper ends of the air pipes are welded on the upper end of the furnace shell to communicate with the spiral wind chamber, and the lower ends of the air pipes penetrates through the lower part of the furnace wall into the furnace chamber. The starting position of the lower spiral wind chamber outside the furnace shell is provided with a blower pipe. The cold air blown by a high pressure blower enters into the furnace through the wind chamber and the air pipes to get the purpose of cooling down the furnace body, absorbing heat and supplying wind. The utility model has the advantages of simple structure, less investment, energy saving, high efficiency and safe and simple production.
Description
The utility model belongs to field of metallurgy, particularly relates to the smelting furnace of wind metal smelting.
It is at present, much local that still hot-blast stove is done periodically mixed wind, accumulation of heat, air feed is worked by turns provides the smelting furnace of hot blast with being furnished with.In the continuous smelting production process, body of heater heat-carrying, temperature raise, influence smelting furnace production, therefore adopt water under high pressure to be centered around the following current shower of the high temperate zone of furnace bosh, cooled furnace wall or adopt and circulate but cool at furnace body outer wall making interlayer cavity water jacket injection high pressure soft water or carbonated drink.Like this, occurred that auxiliary equipment is huge, complex process, problem that investment is big.
The purpose of this utility model is, improves prior art, and a kind of with air cooling and body of heater self-heating high temperature air feed, simple in structure, small investment, the saving energy, efficient height, smelting furnace that production safety is easy are provided.
The technical solution of the utility model is: welded the spiral road from bottom to top at body of heater self outer wall, outside, spiral road encircles body of heater and has welded furnace shell, forms the spirality air compartment; In the outer garden week of body of heater equally distributed minute airduct has been installed vertically, each minute, the upper end that is welded on furnace shell, upper end of airduct communicated with the spirality air compartment, the lower end of airduct was passed the bottom, furnace wall respectively and was entered burner hearth each minute, and bottom spiral air compartment original position has been welded the blower that communicates with the spiral air compartment outside furnace shell.Evenly distribute at furnace body outer wall along spiral air compartment bottom and to have welded heat pipe.
Be connected the cold wind that the high pressure positive blower of blower end blasts and enter the spiral wind indoor circulation, constantly draw the heat of heat pipe, furnace wall, become the hot high pressure air-flow and inject a burner hearth, quicken the melting of furnace charge from minute airduct through the cupola well air channel.Not only cooling protection body of heater but also finished the furnace wall and returned in the stove from fabricate-heat wind, reached the air order but with the purpose of self-heating high temperature air feed.
Excellent beneficial effect of the present utility model is, 1, the utility model is simple in structure, and small investment can be saved equipment investment 50%.2, owing to, return in the stove, therefore improved 20% heat from fabricate-heat wind from the idol cooling.3, because no ancillary device running wearing and tearing have reduced the Manufacturing Worker, reduced the use amount of metallurgical coke,, reduced production cost so saved the energy.4, owing to be easy to resettlement, need not a large amount of waters, thus can adapt to copper, iron, lead, etc. remote mountains, the Gobi desert mining point of mineral resources, can utilize fragmentary, dispersion, the mineral resources that haul distance is far away.5, the scope of application is wide, and the high pressure air pipeline of multi-form circulation can be set according to the different type of furnaces such as vertical, horizontal rotary furnace, open hearth and cement calcination rotary kiln, shaft kiln etc.Reach oxygen enrichment when 6, mixing the humidification gasification air, strengthened the molten speed of material in the stove as spraying water because of melting in the stove.
Accompanying drawing 1 is looked schematic diagram for broken section master of the present utility model, and Fig. 2 is a broken section schematic top plan view of the present utility model.
Below in conjunction with description of drawings example of the present utility model: from the hot blast smelting furnace, comprise furnace lining 1, body of heater 2, spiral road 3, spiral air compartment 4, divide airduct 5, heat pipe 6, furnace shell 7, ajutage 8, welded spiral road 3 from bottom to top at body of heater 2 self outer wall, 3 outsides, spiral road encircle body of heater and have welded furnace shell 7, formed spirality air compartment 4; In the outer garden week of body of heater uniform branch airduct 5 has been installed vertically, each minute airduct 5 upper end be welded on furnace shell 7 the upper end, communicate with the spirality air compartment, airduct 5 lower end passed the bottom, furnace wall respectively and entered burner hearth each minute, and itself and furnace shell and body of heater joint are soldered fixing.Evenly welded heat pipe 6 along spiral air compartment bottom surface at furnace body outer wall, bottom spiral air compartment original position has been welded the ajutage 8 that communicates with the spiral air compartment outside furnace shell.In the external packing of body of heater air compartment one deck FBT high efficiency rare-earth heat insulating coatings.(not drawing among the figure) realized the integral heat insulation of body of heater.For cooling off smelting furnace for some reason, be provided with exhaust valve 9 on the top that each wind is in charge of, the bottom is provided with switch valve 10.Body of heater, spiral road, furnace shell are all used the heat-resisting steel sheet and plate welding fabrication.
