The high-temperature hanging furnace top with the thermal-insulation device includes a refractory material layer (1), a heat-preservation layer (2), a cover layer (3), anchoring bricks and hooks (5), and is characterized by including a fiber carpet (6) and insulation sleeves (7), wherein the insulation sleeves are knitted through fibers; the fiber carpet (6) is laid between the refractory material layer (1) and the heat-preservation layer (2); and the hooks (5) are sleeved with the insulation sleeves (7). The high-temperature hanging furnace top can save energy remarkably, reduce the maintenance work load, and prolongs service life.
Description
Technical field
The utility model relates to the furnace roof field of accessories that is used for general stove, kiln, oven or retort, is specially a kind of high temperature with adiabatic apparatus and hangs furnace roof.
Background technology
Temperature is up to more than 1200 degree in the stove of high-temperature heater, and general the employing hung furnace roof, and the structure that routine is hung furnace roof comprises three layers, and is as shown in Figure 1, be inboard near the one side of the layer of anti-material the in the stove, and the inboard is the layer of anti-material the 1, and the employing refractory material casting forms; The skin of the layer of anti-material the 1 is a heat-insulation layer 2, adopts the cast of light thermal-insulation pours to form, and the skin of heat-insulation layer 2 is a cover layer 3, adopts hardboard to be laid between two adjacent anchored bricks 4, and hook 5 catches on the gib head at anchored brick 4 tops.Adopt this structure, in use anchored brick 4 is easy to generate the expansion clearance with the layer of anti-material the 1 of periphery with heat-insulation layer 2, spills red point; The hull-skin temperature of anchored brick 4 is high, can reach about 250 ℃, usually; The upper surface area of anchored brick 4 accounts for about 10% of whole hanging furnace top area; And hang under the normal condition anchored brick 4 in the furnace roof with the temperature of exterior domain between 120 ℃～140 ℃ because the temperature of anchored brick 4 is high, cause great amount of heat to scatter and disappear; Bring influence also for the plant maintenance of hanging furnace roof, reduced the service life of hanging furnace roof.
The utility model content
In order to overcome the defective of prior art, provide a kind of furnace heat to scatter and disappear less, hang the long furnace roof annex of life of arched roof, the utility model discloses a kind of high temperature and hang furnace roof with adiabatic apparatus.
The utility model reaches goal of the invention through following technical scheme:
A kind of high temperature with adiabatic apparatus is hung furnace roof, comprises the layer of anti-material the, heat-insulation layer, cover layer, anchored brick and hook, and the layer of anti-material the, heat-insulation layer and cover layer set gradually from the bottom to top; Insert in the layer of anti-the material bottom of anchored brick, and the middle part of anchored brick is enclosed within the heat-insulation layer, and the top of anchored brick passes heat-insulation layer; Cover layer covers the outer surface of heat-insulation layer and is located between the adjacent anchored brick; Hook catches on the gib head at anchored brick top, and it is characterized in that: also comprise tapetum fibrosum and insulation sleeve, tapetum fibrosum is layed between layer of anti-material the and the heat-insulation layer; Insulation sleeve forms with fibrage, and insulation sleeve is enclosed within on the hook.
Described high temperature with adiabatic apparatus is hung furnace roof, it is characterized in that: cover layer adopts adiabatic coating to spread upon the outside of heat-insulation layer.
The utility model adds tapetum fibrosum as separation layer between layer of anti-material the and heat-insulation layer, the layer of anti-the material is generally heavy pours or moldable, and thermal conductivity factor is bigger; And tapetum fibrosum adopts resistant to elevated temperatures ceramic fibre; Thermal conductivity factor is very low, and this just makes that the temperature that adopts the light thermal-insulation pours to build the heat-insulation layer that forms significantly reduces, and the tapetum fibrosum quality is soft simultaneously; Solve layer of anti-material the and the staggered floor displacement problem that heat-insulation layer produces because of the coefficient of expansion is different, reduced anchored brick gap on every side.
The outermost layer that the utility model is hung furnace roof at high temperature is smeared adiabatic coating to form cover layer; The thermal conductivity factor of adiabatic coating is very low; Through multilayer have after smearing high temperature resistant, do not ftracture, the characteristics of low heat conduction, can play good insulation effect, be put on anchored brick around; And can not produce the gap between the anchored brick, fundamentally avoid the appearance of red point.
Be lined with insulation sleeve between the utility model hook and the anchored brick, the hook of metal material does not directly contact anchored brick, has reduced anchored brick through the hook heat radiation.
Adopt the utility model, 200 ℃ of anchored brick upper surface temperature-averagings have reduced by 50 ℃ than conventional design, and the average radiation loss of furnace roof reduces by 10%.The beneficial effect of the utility model is: reduce scattering and disappearing of furnace heat, remarkable energy saving effect is arranged, reduced the maintenance of hanging furnace roof, prolonged the service life of hanging furnace roof.
