Abstract
The utility model relates to a multi-layer air sandwich furnace lining, which is a new pattern insulated furnace lining sufficiently adopting the characteristic of the low thermal conductivity coefficient of the air. The utility model makes use of the temperature preformed layer block which is formed by the adhesion of the aluminum silicate fiber and the heat insulating layer is very convenient to be built. The new pattern multi-layer air sandwich furnace lining has the advantages of good heat insulating property, material saving and good energy saving effect and is suitable for most of the industrial furnace, particularly for the furnace changing of energy saving of the heat treatment resistor furnace and the design of the new electric furnace.
Description
The utility model belongs to the Industrial Stoves manufacturing technology
Realize the energy-conservation problem recent and at a specified future date that is countries in the world in Industrial Stoves manufacturing technology field of industrial furnace by transforming furnace lining, great efforts has all been made for this reason by each state for this reason.Traditional industrial furnace kiln lining combines by flame retardant coating and heat-insulation layer, the appearance of entire fibre lining, and two combine into one flame retardant coating and heat-insulation layer.But because entire fibre lining intensity is low, the cost height is not that all occasions all can use, and for reducing cost, enlarges the range of application of fibre furnace lining, proposes the present invention.
As everyone knows, the thermal conductivity factor of air is 0.021 kilocalorie/kilocalories per hour ° ℃ to be about 1/10 of general insulation material.Strengthen the porosity in the insulation material, thermal conductivity factor is descended.The utility model changes the heat-insulation layer of industrial furnace into multi-layer air interlayer furnace lining based on above-mentioned principle, makes full use of the heat-insulating property of air, and the thermal conductivity factor of heat-insulation layer is descended significantly.Concrete structure as shown in Figure 1, forming with air layer (3) with low-grade aluminosilicate fiberboard and rock cotton board (4) is the sandwich construction of interlayer, in air blanketing (3), make dividing plate to stop the thermal convection current in the air blanketing with fiberboard (2) or (5), dividing plate can be strip (2) or corrugated (5) or other arbitrary graphic pattern, and dividing plate in the air blanketing and fibrolamellar (4) are bonding with bonding agent.The characteristics of this structure are not convection current of air between dividing plate and the interlayer, have sufficient intensity to be convenient to build by laying bricks or stones, and what it can make different size in advance gives the making sheet piece, is used for the heat-insulation layer of different Industrial Stoves, and its proportion further alleviates, and materials significantly reduce; The 2nd, thermal conductivity factor descends significantly, and heat-insulating property obviously improves, and casing temperature descends greatly, and radiation loss reduces, and energy-saving effect is remarkable.
In general the furnace lining of warm batch-type furnace its consist of: flame retardant coating is that bat thick (115mm) heat-insulation layer is 1 brick thick (230mm), and flame retardant coating is generally used slight clay brick, heat-insulation layer available silicon cob brick or biotite.When furnace temperature reached 950 ℃, casing temperature can reach 80 ℃.If during with this new structure, 230mm multi-layer air interlayer furnace lining can combine with low-grade aluminosilicate fiberboard, to the high temperature furnace furnace lining, and the high slightly aluminosilicate fiberboard of 1/2 thick available quality then, the sour silica fibre plate of other 1/2 thick available poor quality or use the rock wool fibers plate.Cost is further reduced.Facts have proved by such transformation, can guarantee that casing temperature is in 60 ℃.
Facts have proved, adopt the chamber type electric resistance furnace effect of this novel heat insulation furnace lining remarkable, is example with R * 75 a kilowatt batch-type furnace fire door only.The temperature of this fire door shell can reach 100～110 ℃ before transforming when furnace temperature is 900 ℃, and under the same conditions, the fire door skin temperature drops to 60～70 ℃ after transforming with this novel furnace lining, weight saving, and cost is identical substantially, and energy-saving effect is obvious.Has very high practical value.Particularly be applicable to the design that changes the energy-conservation and novel resistance furnace of stove of heat-treatment furnace.
Fig. 1 is a multi-layer air interlayer furnace lining schematic diagram, 1 refractory lining among the figure, and 2 strong dividing plates, 3 air blanketings, 4 aluminosilicate fiberboards or rock cotton board, 5 corrugations are strengthened dividing plate.
