The low-energy-consumption, thermal-insulation and heat-insulating cupola furnace is low in energy consumption, good in thermal-insulation and heat-insulating effect, and meanwhile suitable for production of high-performance rock wool, and comprises a loading system, the cupola furnace, a centrifugal machine, a high-speed conveying mechanism, a pleating machine, a pressure machine, a curing oven, a transition conveyor, a cooling conveyor, a score cut conveyor, a broken edge conveyor, a length measuring conveyor, a front belt conveyor, a cross-cut flying saw, a back belt conveyor, a cutting knife, a dust collecting device and a tail end conveyor, wherein a thermal-insulation and heat-insulating coating layer with the thickness of 10-12 mm and capable of resisting high temperature of 2,000 DEG C is coated on a metal surface of an inner wall of a furnace chamber of the cupola furnace, basalt lava is added into the low-energy-consumption, thermal-insulation and heat-insulating cupola furnace for smelting, the melt temperature of the raw material is controlled within the range of 1,680-1,720 DEG C, the cupola furnace adopts hot air combustion-supporting gas and the preheat temperature of the gas is 120-130 DEG C so as to improve the melt rate, lower the coke rate and improve the boiler temperature, as a result, the average diameter of produced rock wool fibers is 4 mum, the length of the rock wool fibers is 35-45 mm, and the flexibility is good.
Description
Technical field
The utility model relates to and had a kind ofly not only had that energy consumption is low, but also to have a heat insulation and preservation effect good, is applicable to simultaneously the less energy-consumption heat-insulation and heat-preservation cupola furnace that the high-performance rock wool produces, and belongs to cupola furnace and make field.
Background technology
Existing domestic its essential structure of cupola furnace of for rock wool, producing is comprised of burning zone (burner hearth), preheating section, chimney, three parts.Inboard wall of furnace body and outer wall be by two layers of steel plate by the stiffening web one that is welded, the isolated heat of middle water flowing and extraneous conduction, inboard wall of burner hearth is metallic substance.Its not middle part: the one, because the inboard wall of burner hearth metal directly contacts with fuel, the part heat is recycled water by the inwall metal and takes away, and the overall heat loss is large; The 2nd, adopt the warm air that obtains by cupola furnace tail gas and freezing air heat exchange as combustion-supporting gas, to hang down and cause in stove heat-up rate slow due to temperature, fuel combustion is insufficient, causes that the rock wool fibers of producing is short and thick, snappiness and poor flexibility.
The utility model content
Purpose of design: avoid the weak point in background technology, design and a kind ofly not only had that energy consumption is low, but also to have a heat insulation and preservation effect good, is applicable to simultaneously the less energy-consumption heat-insulation and heat-preservation cupola furnace that the high-performance rock wool produces.
Design: in order to realize above-mentioned purpose of design.the application one is by being the anti-2000 ℃ of high temperature insulating thermal insulation coatings layers of the thick HX-012/1800 of 8-12mm at hearth of cupola furnace inwall metallic surface coated thickness, the novel material that is derived by the space technology of spacecraft heat insulating due to this high temperature insulating thermal insulation coatings layer, have high temperature resistant, waterproof, fire prevention, anticorrosion, wear-resisting, the multiple advantages such as insulation, the nano ceramics technology that application of paints is up-to-date, by high temperature adhesive, nanometer pyroceramic microballon, various high temperature fillers, specialist additive forms, but long term operation is in the hot environment of 1900 ℃, thermal conductivity 0.03 W/m.K, can effectively suppress and radiation-screening heat and heat by conduction, heat insulation suppression efficiency can reach more than 90%, can suppress the thermal radiation of high temp objects and scattering and disappearing of heat, can produce elongated under less energy-consumption, soft, the high quality rock wool of good springiness, and help fiber folded while with this rock wool production, producing asbestos product, can production intensity high, the rock wool product that heat insulation property is good.Secondly, when hearth of cupola furnace inwall metallic surface coated thickness was the anti-2000 ℃ of high temperature insulating thermal insulation coatings layers of the thick HX-012/1800 of 10.5-11mm, its cupola furnace can reduce 88 ﹪ of thermosteresis--92 ﹪, produces beyond thought technique effect.
Technical scheme: a kind of less energy-consumption heat-insulation and heat-preservation cupola furnace, comprise cupola furnace, hearth of cupola furnace inwall metallic surface coated thickness is the heat insulating coatings layer of 8mm-12mm, anti-2000 ℃ of high temperature.
The utility model is compared with background technology, and the one, by after the high temperature resistant 2000 ℃ of heat insulating coatings of hearth of cupola furnace inwall metallic surface coated HX-012/1800, in burner hearth, calorific loss has obtained greatly reducing, and furnace temperature improves; The 2nd, adopt hot wind for combustion supporting gas, make fuel combustion more abundant, reduce coke ratio, not only can reduce energy consumption, also can improve the quality of rock wool fibers, make precondition is provided for production high-performance rock wool.
