A low temperature insulation layer is equipped in the interior-wall of the furnace; a high temperature insulation layer which consists of folded agglomerations of aluminosilicate fiber, is provided on the low temperature insulation layer which is arranged on the top and side of the boiler. The low temperature insulation layer on the bottom of furnace body is provided with a high temperature insulation layer which consists of fire-resistant clunch. The utility model has the advantages of low thermal storage in fiber moisturizing structure, little space occupying, little heat loss and energy saving; compared with fire-resistant clunch and bricks, the utility model can improve the rate of using heat energy by 35per cent; the fiber moisturizing structure has positive effects of low heat conductivity coefficient, good performance of moisturizing, slow calefaction speed of furnace wall, long service life as well as convenience to be repaired.
Description
Technical field
The utility model belongs to the Industrial Stoves field, relates in particular to a kind of thermal insulation furnace body.
Background technology
Existing Industrial Stoves insulation construction is generally: nexine is built into by common refractory brick, and skin is the iron plate cover, the heat-insulation layer that the centre is made up of perlite, vermiculite.Because common refractory brick size is less, is the plane all around, the flame retardant coating seam that is built into is many, the seam crossing poor sealing easily produces gas leakage, leaks cigarette, scurries defectives such as fire and boiler surfaces temperature exceeding standard, causes radiation loss big, and refractory brick is short service life, and maintenance is also inconvenient.Perlite, vermiculite body are loose in addition, and construction, inconvenient maintenance are formed with refractory brick, and mechanical strength, anti-seismic performance are relatively poor, therefore, directly have influence on the thermal efficiency and the service life of Industrial Stoves.
Summary of the invention
The technical problems to be solved in the utility model is exactly that existing Industrial Stoves insulation construction amount of stored heat is big, heat loss is big, and service life is short, and problems such as maintenance inconvenience provide a kind of thermal insulation furnace body, especially a kind of continuous annealing furnace thermal insulation furnace body.
The utility model realizes by following technical solution,
The utility model comprises body of heater, furnace wall, it is characterized in that: be provided with the low temperature thermal insulation layer at inboard wall of furnace body, be provided with the high temperature insulating layer that the alumina silicate fibre folded piece is formed on the low temperature thermal insulation layer of body of heater top and sidepiece; On the low temperature thermal insulation layer of body of heater inner bottom part, be provided with the high temperature insulating layer of forming with fire clay.Described alumina silicate fibre folded piece adopts the alumina silicate fibre folded piece of volume compression 40%.
The low temperature thermal insulation layer is made up of rock cotton board or the knitting blanket of alumina silicate fibre.
The material of forming high temperature insulating layer and low temperature thermal insulation layer is separately by alternating structure laying anyhow.
The alumina silicate fibre folded piece of inboard wall of furnace body top and sidepiece is fixed on the top or sidepiece of inboard wall of furnace body by riveting component.
At the surface of alumina silicate fibre folded piece spraying one deck high-temperature resistant coating.
The beneficial effects of the utility model are: fiber thermal insulation structure amount of stored heat is little, the volume that takes up room is little, heat loss is few, energy efficient; Compare with chamotte brick and can improve heat energy utilization rate nearly 35%; Fiber thermal insulation structure long service life, easy to maintenance; The fiber thermal insulation structure has the low good heat insulating of thermal conductivity factor, and the furnace wall temperature rise is low.
Description of drawings
Fig. 1 the utility model structural representation
Fig. 2 is a partial enlarged drawing among Fig. 1
Fig. 3 be among Fig. 2 B to view.
The specific embodiment
Earlier rock cotton board is arranged in uniformly the top and the sidepiece of inboard wall of furnace body, when construction, guarantee to replace anyhow, and staggered mutually in the slit, side is laid one group of alumina silicate fibre folded piece is staggered anyhow within it then, because the alumina silicate fibre folded piece has retractility, the alumina silicate fibre folded piece that the utility model adopts is that volume compression 40% is 60% of a boil down to alumina silicate fibre folded piece normal size.Adopt perpendicular building block shape structure as Fig. 2, alumina silicate fibre folded piece shown in Figure 3, building method is staggered perpendicular the block, and adopt the riveting component that is fixed on the inboard wall of furnace body that the alumina silicate fibre folded piece is fixed on the rock cotton board, rivet or riveting bolt that rivet clasp adopts exotic material to make surely, at the resistant to elevated temperatures high-temperature coatings of the surface of alumina silicate fibre folded piece spraying one deck, after solidifying, high-temperature coatings make the alumina silicate fibre folded piece form overall structure, prevent the blow brush of gas stream in the stove, prolong the service life of alumina silicate fibre folded piece the alumina silicate fibre folded piece.The composite structured mechanism of heat insulation that this rock cotton board combines with the alumina silicate fibre folded piece is: the alumina silicate fibre folded piece of internal layer be high temperature resistant and when high temperature good heat-insulation effect, and the temperature when treating that temperature in the stove passes to the folded piece outside has been lower, and in this outside effect of heat insulation when having arranged rock cotton board preferably, thereby guarantee that furnace heat is not dispersed into furnace shell to low temperature.
The furnace lining of furnace bottom adopts knitting blanket of alumina silicate fibre and light-weight refractory clay structure combining, and this structure has good heat-insulation effect, builds by laying bricks or stones other work that waits is installed in laggard people's stove, and furnace bottom can not be out of shape.When making, earlier the knitting blanket of alumina silicate fibre is arranged in uniformly the bottom, when construction, guarantees to replace anyhow, and staggered mutually in the slit, straight joint can not be arranged.Build by laying bricks or stones on the knitting blanket of alumina silicate fibre with the light-weight refractory clay is staggered then.The composite structured mechanism of heat insulation that the knitting blanket of this employing alumina silicate fibre combines with the light-weight refractory clay is: the light-weight refractory clay of internal layer be high temperature resistant and when high temperature heat-insulating property better, and the temperature when treating that temperature in the stove passes to the knitting blanket of alumina silicate fibre has been lower, and outside this, arranged the knitting blanket of the good alumina silicate fibre of effect of heat insulation, thereby guarantee that furnace heat must not be dispersed into furnace shell.
After adopting the utility model insulation construction, not only prolonged the service life of furnace insulation structure, thermal insulation, thermal insulation are preferably arranged again simultaneously, premium properties such as anti-thermal shock and mechanical shock, improved the heat energy utilization rate, reached energy-conservation effect, and alumina silicate fibre folded piece easy accessibility, be easy to maintenance.
