Abstract
The utility model relates to a two-layer composite stove hearth. The utility model is composed of a basal hearth made of aluminum silicate fibre felt and a ceramic protective layer. The ceramic protective layer is compositely arranged on the inner wall of the basal hearth, which plays the action of isolating direct contact friction of the honeycomb briquette and the basal hearth when the honeycomb briquette is added into the basal hearth. The stove hearth has thin wall, light weight and favorable heat insulating performance. Meanwhile, owing to large expansion coefficient of the aluminum silicate fibre felt, the utility model has difficult break and long service life.
Description
The utility model relates to a kind of flue of domestic honeycomb coal stove.
The flue of existing domestic honeycomb coal stove all adopts ceramic material such as fire clay to make, and exists courage wall thickness, big, poor, the breakable shortcoming of insulation of weight.
The purpose of this utility model is to propose a kind of two-layer compound flue, and it can improve heat-insulating property effectively, and in light weight, is difficult for broken.
The utility model is made up of an alumina silicate fiber felt base courage and ceramic protective layer, and the ceramic protective layer is compounded in the inwall of alumina silicate fiber felt base courage.Because the alumina silicate fiber felt poor thermal conductivity, thermal capacitance is little, thereby has guaranteed the heat-insulating property of flue; Simultaneously, basic courage has good dilatancy and toughness again, thereby it is broken that it is difficult for.
The utility model is because only need be bonding with basic courage and ceramic protective layer, so structure is very simple.Compare with existing ceramic flue, have characteristics such as wall is thin, light weight, good heat preservation performance.Broken owing to being difficult for simultaneously, so, can increase the service life exponentially.
Concrete structure of the present utility model is provided by the following drawings and embodiment.
Fig. 1 is a two-layer compound single core furnace courage three-dimensional cutaway view.
Fig. 2 is three layers of compound single core furnace courage three-dimensional cutaway view.
Fig. 3 is three layers of compound splicing formula, three core flue schematic perspective views.
Fig. 4 is three layers of compound splicing formula four-core stove schematic perspective view.
Do further describing of embodiment below in conjunction with accompanying drawing: this flue has an alumina silicate fiber felt base courage (1), and wall has one deck ceramic protective layer (2) again within it.The base courage (1) by alumina silicate fiber felt with resistant to elevated temperatures binder-impregnated after press forming; Protective layer (2) forms (also available other ceramic material) by assembly such as kaolin powder and quartz sands, directly be compounded on the inwall of basic courage, the two-layer compound flue.Protective layer mainly plays buffer action, promptly avoids adding when getting honeycomb briquette, produces contact friction with basic courage and damages.Be to improve effect of heat insulation, can compound again one deck thermal insulation layer (3) at the outer wall of basic courage (1), thermal insulation layer can adopt and the same material of protective layer, and also available other material is as iron sheet etc.
This flue can be processed into single core courage, perhaps three core courages, and perhaps four-core courage, three core courages adopt 3 semi-circular courages (4) to be spliced; The four-core courage adopts 4 semi-circular courages (4) to be spliced, and like this, in use in case aging damaged, burst is substituted easily.
Claims (4)
1, a kind of two-layer compound flue is characterized in that this flue is made up of an alumina silicate fiber felt base courage (1) and ceramic protective layer (2), and described ceramic protective layer (2) is compounded on the inwall of sial fiber base courage (1).
2, flue as claimed in claim 1 is characterized in that alumina silicate fiber felt base courage (1) outer wall has thermal insulation layer (3) again.
3, flue as claimed in claim 1 or 2 is characterized in that this flue is single core courage or three core courages or four-core courage.
4, flue as claimed in claim 3 is characterized in that described three core courages are made up of 3 semi-circular courages (4); The four-core courage is made up of 4 semi-circular courages (4).
