Abstract

The utility model discloses a kind of cover for kiln head of cement kiln, and it includes:Kiln hood cover body mounting layer, flame retardant coating, sprayed coating, heat-insulation layer and protective layer;It is most inboard that the flame retardant coating is arranged on kiln hood cover body; the flame retardant coating is made up of refractory brick; refractory brick is to be detachably connected; sprayed coating is provided between the refractory brick; heat-insulation layer is arranged between kiln hood cover body mounting layer and flame retardant coating, and protective layer is arranged on kiln hood cover body outermost, during kiln head cover flame retardant coating local damage; only standby corresponding refractory brick need to be used to change, it is quick and convenient;And by the setting of above layers, the service life of whole cover for kiln head of cement kiln greatly prolongs, and saves material consumption.

Description

A kind of cover for kiln head of cement kiln
Technical field
It the utility model is related to fire resisting kiln field, and in particular to a kind of cement kiln head cover structure.
Background technology
Kiln head cover is to connect kiln hood end and the intermediate of next procedure equipment in flow, and it is located at turn around the exhaust end of kiln, Coal injection pipe gos deep into kiln body through kiln head cover.In order to prevent the bad kiln head cover top of the baked wheaten cake in kiln, generally under kiln head cover top The extension brick of end one layer of fire resisting of mounting, flare and kiln head cover top are isolated.Because leaving vertical masonry joint when hanging brick splicing, flare can pass through straight Seam burns out kiln head cover top.During existing extension brick connection, adjacent two pieces of extension bricks are bonded together by fire clay, prevent flare from passing through Vertical masonry joint;But in bonding, it could be bonded together after brick can only be hung in mounting with fire clay by brick is hung, difficulty is higher, process More complicated, cost is high.
And as rotary kiln develops to maximization direction, empty span is also increasing in kiln head cover, by wear-resisting, cold and hot prominent Become frequent and thermal shock influence, the compound lining formed using calcium silicate board and anti-peeling high aluminium brick uses less than six months just frequencies It is numerous to drop, it is ineffective.
The generally outdoor use of kiln head cover, run into rain and shunk when waiting weather at the top of kiln head cover close to housing position chilling, far Shrinking away from theshell body region temperature is basically unchanged, and it is larger so to often result in deforming tops, causes the accidents such as kiln head cover high temperature deformation, scaling loss.
Utility model content
For the disadvantages described above or Improvement requirement of prior art, the utility model provides a kind of cover for kiln head of cement kiln, passes through Kiln hood cover structure is rationally set, and its service life greatly prolongs, and saves material consumption.
The utility model is that technical scheme is used by solving above-mentioned technical problem:
A kind of cover for kiln head of cement kiln, it includes:Kiln hood cover body mounting layer, flame retardant coating, sprayed coating;The flame retardant coating is arranged on Kiln hood cover body is most inboard, and the flame retardant coating is made up of refractory brick, and refractory brick is provided with to be detachably connected between the refractory brick Sprayed coating.
Specifically, the refractory brick edge has splicing construction;Preferably, the splicing construction is U-lag, and U-lag is most The brim height of outer side is less than refractory brick body height.
Kiln head cover also includes heat-insulation layer, and the heat-insulation layer is arranged between kiln hood cover body mounting layer and flame retardant coating.Preferably, The heat-insulation layer is rock wool.
Kiln head cover also includes protective layer, and the protective layer is arranged on kiln hood cover body outermost.Preferably, the protective layer is Ceramic material.
Compared with prior art, the beneficial effects of the utility model are:
(1) flame retardant coating is spliced by the refractory brick with splicing construction, and assembling easy to disassemble, local damage is easy to more Change, cost is low;
(2) sprayed coating is set between refractory brick, prevents flare string from going out, and sprayed coating performance of expanding with heat and contract with cold is excellent, bonds Property is strong, improves the service life of flame retardant coating;
(3) setting of heat-insulation layer enhances effect of heat insulation, reduces kiln body external temperature, improves kiln body service life;
(4) setting of protective layer prevents from improving using the longevity because environment temperature mutation causes moderate finite deformation outside kiln body Life.
Brief description of the drawings
Fig. 1 is the overall schematic of kiln head cover;
Fig. 2 is Fig. 1 parts A enlarged diagram;
Fig. 3 is the schematic cross-section of refractory brick.
Embodiment
In order that the purpose of this utility model, technical scheme and advantage are more clearly understood, below in conjunction with accompanying drawing and implementation Example, the utility model is further elaborated.It should be appreciated that specific embodiment described herein is only explaining The utility model, it is not used to limit the utility model.In addition, institute in each embodiment of the utility model disclosed below As long as the technical characteristic being related to does not form conflict each other, can is mutually combined.
As shown in figure 1, it is a kind of schematic diagram of cover for kiln head of cement kiln, it includes:Kiln hood cover body 10, kiln hood cover body 10 are pacified On kiln hood platform 6, kiln hood cover body most inner side has flame retardant coating 2.
Fig. 2 is Fig. 1 parts A partial enlarged drawing, and as shown in Figure 1-2, kiln hood cover body 10 includes mounting layer 1, flame retardant coating 2, Sprayed coating 3, heat-insulation layer 4 and protective layer 5;Flame retardant coating is arranged on that kiln hood cover body is most inboard, and flame retardant coating is made up of refractory brick 21, resistance to Firebrick is provided with sprayed coating 3 to be detachably connected between refractory brick, it is preferred that sprayed coating 3 is resistance to from the fire resisting comprising kyanite Hot high viscosity material, sprayed coating is set between refractory brick, prevents flare string from going out, and sprayed coating performance of expanding with heat and contract with cold is excellent, glues Knot property is strong, improves the service life of flame retardant coating;Heat-insulation layer 4 is arranged between kiln hood cover body mounting layer 1 and flame retardant coating 2, preferably , heat-insulation layer is rock wool, and the setting of heat-insulation layer enhances effect of heat insulation, reduces kiln body external temperature, improves kiln body use Life-span;Kiln head cover also includes protective layer 5, and protective layer 5 is arranged on kiln hood cover body outermost, it is preferred that and protective layer is ceramic material, The setting of protective layer prevents from improving service life because environment temperature mutation causes moderate finite deformation outside kiln body.
As shown in figure 3, the edge of refractory brick 21 has a splicing construction, splicing construction is U-lag, the side of U-lag outermost side Edge is highly less than refractory brick body height.Flame retardant coating is spliced by the refractory brick with splicing construction, assembling easy to disassemble, office Portion's damage is easily changed, and cost is low.
As it will be easily appreciated by one skilled in the art that preferred embodiment of the present utility model is the foregoing is only, not To limit the utility model, any modification of all made within spirit of the present utility model and principle, equivalent substitution and change Enter, should be included within the scope of protection of the utility model.
