Abstract
The invention relates to a heat insulation top cover of a heat treatment furnace, which comprises a hanging plate, a close cover and a heat insulation layer arranged between the hanging plate and the close cover, wherein the close cover comprises a frame, heat insulation cotton filled in the frame and covered on the periphery of the frame and a plurality of fixing pieces arranged on the side edges of the heat insulation cotton so as to clamp and fix the heat insulation cotton. Loss of heat in the heat treatment furnace can be effectively avoided through the hanging plate, the close cover and the heat insulation layer. Besides, due to unique design of the close cover (namely the close cover comprises the frame, the heat insulation cotton filled in the frame and covered on the periphery of the frame and the fixing pieces arranged on the side edges of the heat insulation cotton so as to clamp and fix the heat insulation cotton), heat loss can be further avoided, and accordingly good heat insulation is achieved.
Description
Technical field
The present invention relates to a kind of heat-treatment furnace heat-insulation and heat-preservation top cover.
Background technology
See also Fig. 1; Be heat-insulation and heat-preservation top cover commonly used in the heat-treatment furnace in the prior art; This heat-insulation and heat-preservation top cover comprises the fixed bar 6 of outer seal 4, insulating 5 and fixing above-mentioned outer seal 4 and insulating 5; In order to reach firm connection outer seal 4 and insulating 5, being laid on the outer seal 4 of these insulating 5 general superposing types fixed through fixed bar 6 bottoms then.Said fixed bar 6 generally is directly welded in the capping 4, and generally needs a plurality of fixed bars 6 of design to be used to hold insulating 5, prevents that insulating 5 is scattered; The drawback of this kind design is: in heat-treatment furnace, because temperature is very high, generally can only use the high metal materials of fusing point such as iron, because this fixed bar 6 is directly exposed in the stove; And because the heat conductivility of metal material is very good; So when above-mentioned heat-insulation and heat-preservation top cover covered in heat-treatment furnace, fixed bar can be heated; Then heat is passed on the outer seal, and then causes the temperature loss in the stove.
Summary of the invention
The object of the present invention is to provide a kind of good heat insulating and can prevent the heat-treatment furnace heat-insulation and heat-preservation top cover that heat runs off.
The technical solution adopted for the present invention to solve the technical problems is: a kind of heat-treatment furnace heat-insulation and heat-preservation top cover; Comprise boatswain chair, capping and be arranged at the thermal insulation layer between said boatswain chair and the capping, said capping comprises framework, be filled in the framework and be coated on the peripheral heat insulation foam of framework, and several be arranged at the heat insulation foam side in order to clamp and the fixing stator of heat insulation foam.
Further: install for separate type between said boatswain chair, capping and the thermal insulation layer.
Further: design for integral type between said boatswain chair, capping and the thermal insulation layer.
Further: is connected through riveted joint between said boatswain chair and the capping, and through boatswain chair and capping with the thermal insulation layer clamping and be fixed between boatswain chair and the capping.
Further: said heat insulation foam folding successively plug-in type on the boatswain chair vertical direction is arranged in the framework.
The present invention is through boatswain chair, capping and thermal insulation layer; Can prevent effectively that the heat in the heat-treatment furnace runs off; And because the unique design of this capping (that is: capping comprise framework, be filled in the framework and be coated on the peripheral heat insulation foam of framework, and several be arranged at the heat insulation foam side in order to be fixed in the stator of heat insulation foam); Can prevent further that heat runs off, thereby reach good heat insulating ability.
Description of drawings
Fig. 1 is the structural representation of the heat-treatment furnace heat-insulation and heat-preservation top cover that uses in the prior art.
Fig. 2 is the structural representation of heat-treatment furnace heat-insulation and heat-preservation top cover in the specific embodiment of the invention.
Fig. 3 is the structural representation of Fig. 2 middle frame.
Among the figure: 1, boatswain chair; 2, capping; 21, framework; 22, heat insulation foam; 23, stator; 3, thermal insulation layer; 4, outer seal; 5, insulating; 6, fixed bar.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is further specified.
See also Fig. 2; A kind of heat-treatment furnace heat-insulation and heat-preservation top cover comprise boatswain chair 1, capping 2 and be arranged at boatswain chair 1 and capping 2 between thermal insulation layer 3; Said capping 2 comprises framework 21, be filled in the framework 21 and be coated on the peripheral heat insulation foam 22 of framework 21, and several be arranged at heat insulation foam 22 sides in order to clamp and the fixing stator 23 of heat insulation foam 22; Said heat insulation foam 22 is arranged in the framework 21 in the folding successively plug-in type of boatswain chair 1 vertical direction; Through stator 23 the heat insulation foam side is fixedly clamped then; Because sticking together mutually tightly between adjacent two-layer in the folding back of heat insulation foam 22 when arranging be not so can dissipate in (being that heat treatment stove heat-insulation and heat-preservation top cover covers on the heat-treatment furnace) time of putting upside down yet.Said heat insulation foam 22 can be for the heat-barrier material of identical material, like ceramic fiber blanket with thermal insulation layer 3.In the present embodiment; Be that separate type is installed between said boatswain chair 1, capping 2 and the thermal insulation layer 3; In addition; Also can be integral type design between this boatswain chair 1, capping 2 and the thermal insulation layer 3, be connected through riveting between boatswain chair 1 and the capping 2, and thermal insulation layer 3 be clamped between boatswain chair 1 and the capping 2 (not shown) through boatswain chair 1 and capping 2.
In the time of in being covered on heat-treatment furnace, at first through other things that have the pawl system of colluding with capping 2 placements and fire door, because capping 2 is the frame-type structure; And heat insulation foam 32 is when arranging above that, outside the framework of its bottom partly is exposed to, so can it be moved through the thing that colludes pawl system; Be stepped owing to fire door again, thus just in time capping 2 is held, and because stator 23 is arranged at the side of heat insulation foam 22; Be affixed on the fire door side after the installation; Stator is exposed in the stove, then thermal insulation layer 3 is placed on above the capping 2, cover at last and go up boatswain chair 1; At this, can further furnace heat be blocked owing to be provided with thermal insulation layer 3 between capping 2 and the boatswain chair 1.When uncapping, its step and above-mentioned steps are opposite.
Through said structure (promptly at boatswain chair 1, capping 2 and thermal insulation layer 3); Can prevent effectively that the heat in the heat-treatment furnace runs off; And because the unique design of this capping 3 (that is: capping 3 comprise framework 21, be filled in the framework 21 and be coated on the peripheral heat insulation foam 22 of framework 21, and several be arranged at the stator 33 of heat insulation foam 22 sides in order to be fixed in heat insulation foam 32); Prevent that further heat runs off, and reaches good heat insulating ability.
It is emphasized that: above only is preferred embodiment of the present invention; Be not that the present invention is done any pro forma restriction; Every foundation technical spirit of the present invention all still belongs in the scope of technical scheme of the present invention any simple modification, equivalent variations and modification that above embodiment did.
