CN2401800Y - Composite structured integral stove body - Google Patents

Abstract

The utility model relates to a manufacture technology of a briquette coal stove the stove body of which is a composite integration structure formed by a casing, a thermal insulation layer, and a stove core, wherein, the external layer casing is an iron sheet structure, the middle layer is composed of casting materials of vermiculite, perlite, and cement, the internal layer is the stove core which is made of fireclay, the external layer casing and the internal layer stove core are compounded together by the middle thermal insulation layer, and a composite structured integral stove body is formed. When the utility model which is a composite structured integral stove body is used, the root defect of burning loss of the stove body can be avoided. The phenomena of loosening, sinking, gas leakage, and wind leakage of the stove body are eliminated through experiment, the long-term use effect of the stove body is guaranteed, and the service life of the stove body is extended.

Description

The monolithic devices body of heater of composite construction

The utility model belongs to the honeycomb briquette stove manufacturing technology, mainly proposes a kind of monolithic devices body of heater of composite construction.

Along with rapid economic development, family's cooking is fuel used also to develop into liquefied gas, coal gas, natural gas gradually from fire coal; But the user of coal furnace is still a lot, and will keep a stage, especially in the place of some small-sized cities and towns gas supply difficulties such as (rural areas).And in coal furnace, the removable honeycomb briquette stove of small-sized iron sheet housing has its unique distinction, and cost is low, be convenient to move (move the portable indoor and outdoor of being convenient to) also has the characteristics of economizing on coal in addition.Its furnace binding of the honeycomb briquette stove of existing iron sheet housing is: outer is the iron sheet housing, and internal layer is the seat clay combustion chamber, and middle news is filled the insulation material of discrete particles shape or heat-preservation cotton and so on.This structure is because the effect of thermal stress, burning a period of time combustion chamber cracking, sink, under the effect of gravity, strengthened the cracking degree of combustion chamber and gravity is concentrated act on the outsourcing iron sheet, 1/2 high-temperature region, coal stove top is local or all be higher than 380 ℃ high temperature etch, quickened the oxidizing process (from the lining and outside) of iron sheet, again owing to the effect of gravity, descended by the iron sheet bearing capacity of high temperature etch, quickened the damage of iron sheet, therefore the plate the earth has reduced the service life (the discarded coal stove first half damages, and Lower Half is then also intact) of coal stove.

Its purpose of monolithic devices body of heater that the utility model proposes composite construction promptly is to overcome the existing existing above-mentioned defective of honeycomb briquette body of heater, the service life of improving coal stove.

The utility model is finished the technical scheme that its invention task takes: its body of heater is for by housing, heat-insulation layer and the compound integrative-structure of seat clay combustion chamber, and outer casing is an iron sheet structure, and middle heat-insulation layer is

Stone, perlite and cement material, internal layer are the seat clay combustion chamber; Outer casing and internal layer combustion chamber are combined with each other by the material feeding of watering of middle heat-insulation layer, constitute the monolithic devices body of heater of composite construction.

Adopt the monolithic devices body of heater of the utility model composite construction, can avoid the essential defect of coal stove scaling loss.The body of heater of this structure is through the test non-loosening, sinks and gas leakage, runs the wind phenomenon, and coal stove first half high-temperature region does not have the local anomaly high temperataure phenomena, stove outer wall exothermic temperature unanimity in the same warm area, and maximum exothermic temperature (outer wall) is less than 100 ℃.Because the bonds well performance that the middle heat-insulation layer of compound body of heater has outstanding resistance to elevated temperatures and has in hot environment, thereby guaranteed that the seat clay combustion chamber can not enlarge at the impaired crackle that produces of stress that produces because of thermal balance, guarantee that it has good result of use, has prolonged the service life of body of heater.

Do not play the load-bearing effect at the compound body of heater ectomesoderm of the utility model iron sheet housing,, thereby can adopt thin iron sheet, saved cost of manufacture thus only in order to decoration.

Embodiment:

Accompanying drawing 1 is the utility model furnace binding schematic diagram.

In conjunction with the accompanying drawings its structure is further specified:

Structure as shown in drawings, its body of heater 5 are that outer casing 4 is an iron sheet structure by the compound integrative-structure of housing 4, heat-insulation layer 2 and seat clay combustion chamber 3, and middle heat-insulation layer 2 is

Stone, perlite and cement water material feeding, internal layer is a seat clay combustion chamber 3; Outer casing 4 and internal layer combustion chamber 3 are combined with each other by the material feeding of watering of middle heat-insulation layer, constitute the monolithic devices body of heater 5 of composite construction.

1 is furnace upper cover among the figure.

Claims (1)

1, a kind of monolithic devices body of heater of composite construction, include iron sheet housing (4), middle heat-insulation layer (2) and internal layer seat clay combustion chamber (3), it is characterized in that body of heater (5) is by housing (4), heat-insulation layer (2) and the compound integrative-structure of seat clay combustion chamber (3), outer iron sheet housing (4), internal layer combustion chamber (3) are combined with each other by the material feeding of watering of middle heat-insulation layer (2), constitute the monolithic devices body of heater (5) of composite construction.
