Abstract
The invention discloses a fibrous combined type heating cover plate for a radiation pipe, belonging to the field of protection of the radiating pipes. The fibrous combined type heating cover plate comprises a cover plate main body of the radiating pipe and is characterized in that the cover plate main body is fixedly provided with a first ceramic fiber plate/blanket through anchoring members, and an aluminum oxide fiber blanket and ceramic fiber blanket combined lamellar module is arranged at the inner side of the first ceramic fiber plate/blanket. The aluminum oxide fiber blanket and ceramic fiber blanket combined lamellar module can play a role of protecting a stainless steel lining plate, so that not only can the problems of broken fiber bits falling and reaction between fibers and atmosphere inside a furnace not be generated, but also the advantage of compensating connection seams generated due to lining plate deformation to tightly connect a radiating pipe heating plate and a furnace inner lining is achieved, a mounting face is smooth, the roles of heat insulating and sealing are favorably achieved, and the heat loss is reduced; and due to the adoption of the combined type structure, the requirement of the special structure of the heating plate is met, and the effects of heat insulating, sealing and easiness for maintenance are added.
Description
Technical field
A kind of brand-new radiant tube protection field that the present invention provides a kind of alumina fibre blanket to replace the stainless steel liner plate, especially a kind of fiber composite radiant tube heating cover plate.
Background technology
At present, alumina fibre is to adopt chemical colloid method production, Al2O3: SiO2=72: 28, have characteristics such as high temperature resistant, that the heater wire contraction is little, non-fibrous material content is low, wind erosion-resistance performance is strong, and be widely used.
Normally used radiant tube heating cover plate; Operating temperature is less than 1000 ℃; Have nitrogen, hydrogen shield in the stove, cover plate generally is made up of carbon steel panel, radiation heating tube, ceramic fiber blanket and stainless steel protection liner plate, and ceramic fiber blanket and stainless steel protection liner plate adopt anchor studs to fix.
The original structure shortcoming: because the existence of stainless steel protection liner plate, direct heat is transmitted to panel in the stove, takes away a large amount of heats, can produce distortion under the stainless steel lining plate hight temperature simultaneously, causes heating plate and body of heater furnace lining junction the slit to occur, the thermal efficiency of reduction stove.When particularly being applied to more than 5 years, the liner plate bending is serious, causes the panel outside wall temperature to be elevated to more than 150 ℃, problems such as serious occur being out of shape.
Radiant tube damages sometimes, as if liner plate irregularity or distortion, has strengthened installation difficulty during replacing.
Summary of the invention
According to the deficiency of above prior art, the technical problem that the present invention will solve is: provide a kind of and address the aforementioned drawbacks, good energy-conserving effect, easy for installation, reduced the fiber composite radiant tube heating cover plate that heat scatters and disappears.
The technical solution adopted for the present invention to solve the technical problems is: a kind of fiber composite radiant tube heating cover plate; The cover board body that comprises radiant tube; It is characterized in that: cover board body is through fixing first ceramic beaverboard of anchoring piece/blanket, and first ceramic beaverboard/blanket inboard fixedly installs alumina fibre blanket and the complex layered module of ceramic fiber blanket.
On the carbon steel cover board body, the weld anchor firmware, ceramic beaverboard/blanket is laid in layer shop, and the anchoring piece through special use is alumina fibre blanket and the complex layered module of ceramic fiber blanket fixedly.Realization anchor studs huyashi-chuuka (cold chinese-style noodles) is fixed, and anchor studs hot side and the unconnected effect of huyashi-chuuka (cold chinese-style noodles).The complex layered module of alumina fibre blanket and ceramic fiber blanket can play the protective effect of stainless steel liner plate; The problem that fiber falls slag, fiber and furnace atmosphere reaction neither can take place, and plays compensation again and remedying the connection slit that the liner plate distortion causes, make be connected in radiant tube heating plate and the inner lining of furnace tight; Installed surface is smooth; Can well play insulation and sealing effectiveness, reduce heat and scattered and disappeared the employing of this composite construction; Satisfy the requirement of the special construction of heating plate, increased insulation, sealing, effect for ease of maintenaince.Ceramic fiber blanket is 1260 types or other model tapetum fibrosum.
Wherein preferred version is:
Described alumina fibre blanket comprises identical second ceramic beaverboard of the several layers that is fixed together/blanket with the complex layered module of ceramic fiber blanket, and external stability is provided with the alumina fibre blanket.Arriving the surface is complete be alumina fibre blanket, smooth, the fixation of structure.
Described alumina fibre blanket coats first ceramic beaverboard/blanket.Further increase sealing, heat insulation effect.
The beneficial effect that the present invention had is:
Removed surface and stainless steel protection liner plate all around, energy saving is obvious; Fibre furnace lining can be with fast arbitrarily speed heating or cooling, and long-term the use do not have the slag of falling, and do not have harm, and thermal shock resistance is good; Compound lining is in light weight, and the construction weight of heating plate own is alleviated, and makes the installation of heating plate and lifts by crane convenient; The anchoring piece hot side is not connected with huyashi-chuuka (cold chinese-style noodles), has not only effectively reduced because the heat loss that the high thermal conductivity of metal causes makes the material of anchoring piece reduce simultaneously, has reduced the cost of metalwork.
Description of drawings
Fig. 1 is a structural representation of the present invention;
Wherein: 1, cover board body 2, ceramic beaverboard 3, anchoring piece 4, alumina fibre blanket 5, ceramic beaverboard/blanket.
The specific embodiment
Below in conjunction with accompanying drawing embodiments of the invention are done and to be further described:
Embodiment 1:
Like Fig. 1, shown in Figure 2, the cover board body 1 of radiant tube passes through fixedly ceramic beaverboard 2 of anchoring piece 3, and ceramic beaverboard 2 inboards are provided with alumina fibre blanket and the complex layered module of ceramic fiber blanket.The alumina fibre blanket comprises the identical ceramic beaverboard/blanket 5 of the several layers that is fixed together with the complex layered module of ceramic fiber blanket, and external stability is provided with alumina fibre blanket 4, and arriving the surface is complete be alumina fibre blanket 4, smooth, the fixation of structure.
Embodiment 2:
Operation principle and use:
On carbon steel cover board body 1, weld anchor firmware 3, ceramic beaverboard/blanket is laid in layer shop, and the anchoring piece 3 through special use is alumina fibre blanket and the compound fold shape of ceramic fiber blanket module fixedly.The complex layered module of alumina fibre blanket and ceramic fiber blanket can play the protective effect of stainless steel liner plate, and the problem that fiber falls slag, fiber and furnace atmosphere reaction neither can take place, and plays compensation again and remedies the connection slit that the liner plate distortion causes; Make and be connected in radiant tube heating plate and the inner lining of furnace closely; Installed surface is smooth, can well play insulation and sealing effectiveness, has reduced heat and has scattered and disappeared; Satisfy the requirement of the special construction of heating plate, increased insulation, sealing, effect for ease of maintenaince.
