Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to household and general incinerators, and more specifically to a furnace wall designed to reduce thermal shock and mechanical shock applied to the furnace wall and facilitate manufacturing. Is related to the structure of.

[0002]

2. Description of the Related Art Conventionally, the furnace wall of this type of incinerator is mainly made of iron or concrete, and in the former case,
There was a drawback that rust was generated within a short period of time, the surrounding living environment was damaged, and the life was short. In the latter case, the wall thickness of the furnace wall becomes unnecessarily thick, the weight increases, and further, when repeatedly subjected to expansion / contraction stress, cracks occur. In order to eliminate such drawbacks, it is effective to use a structure in which furnace walls made of materials such as chamotte, clay, and diatomaceous earth are combined in combination, but one furnace wall having different thermal expansion coefficients is used. In order to finish the insertion into another furnace wall, the dimensional accuracy is extremely strict and a high level of technology is required.

[0003]

SUMMARY OF THE INVENTION The present invention has been made to solve the drawbacks described in the prior art, and reduces the thermal shock and mechanical shock to the furnace wall, which has been difficult in the past. The purpose is to make the incinerator consisting of walls easy and practical.

[0004]

A buffer layer or a carbon fiber made of a fiber member such as carbon fiber, ceramic fiber, metal fiber or shape memory fiber is provided between a furnace inner wall having heat storage property and a furnace outer wall having heat insulation property, A buffer layer having slits made of fiber members such as ceramic fibers, metal fibers and shape memory fibers is interposed.

The inner wall of the furnace is composed of a block member formed by attaching a buffer layer made of the fiber member or a buffer layer made of the fiber member and having slits to the back surface.

The outer wall of the furnace is composed of a buffer layer made of the above fiber member or a block member made of the outer wall of the furnace made of the above fiber member and having a slit buffer layer attached to the inner surface thereof.

[0007]

The buffer layer made of the fiber member or the buffer layer made of the fiber member and having the slit absorbs the displacement caused by the thermal expansion or contraction of the furnace wall, and alleviates the thermal shock applied to the furnace wall. Further, the buffer layer made of a fiber member or the buffer layer made of a fiber member and having a slit absorbs mechanical impact force such as vibration applied to the furnace wall. By providing the slits in the buffer layer, it is possible to absorb and mitigate larger thermal shock and mechanical shock.

When the furnace itself is large, the temperature of the furnace can be controlled by providing a conductive fiber member such as carbon fiber with heat generating property and heat absorbing property. Further, the buffer layer made of the shape memory fiber member, by setting the original shape of the shape memory fiber member to return to the original shape at a temperature at which the force applied to the furnace wall from inside and outside the furnace is maximized, The furnace wall strength can be reinforced.

[0009]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring to the drawings showing an embodiment of the present invention, for example, in a furnace wall of an incinerator 12 including an inlet 9 for combustible waste, a chimney 10, legs 11, etc., diatomaceous earth, etc. A buffer layer 3 made of a fiber member such as carbon fiber, ceramic fiber, metal fiber or shape memory fiber between a furnace inner wall 1 made of fine ceramics and having a heat storage property, and a furnace outer wall 2 made of heat-resistant clay, chamotte or the like having heat insulating properties. Alternatively, a buffer layer 3 ′ made of a fiber member such as carbon fiber, ceramic fiber, metal fiber, or shape memory fiber and provided with slits 4 is interposed.

Further, in order to efficiently carry out the manufacturing and assembling, the buffer layer 3 which is divided at the manufacturing stage and is made of a fiber member.
A block member 5 formed by adhering to the back surface, or a block member 6 formed by adhering to the back surface a buffer layer 3 ′ made of a fibrous member and provided with slits 4, and assembling it,
The furnace inner wall 1 having heat storage properties may be configured.

In order to efficiently manufacture and assemble,
At the manufacturing stage, a block member 7 which is divided and a buffer layer 3 made of a fiber member is attached to the inner surface, or a block member 8 made of a fiber member and a buffer layer 3 ′ provided with a slit 4 is attached to the inner surface is produced. The furnace outer wall 2 having heat resistance may be configured by assembling them. The buffer layer 3,
In order to enhance the function of the fiber member forming 3 ', protrusions, stripes, voids, etc. may be provided on the surface of the fiber.

[0012]

[Effect] Since the present invention is configured as described above,
It has the following effects.

Since the inner wall of the furnace has a heat storage property, the temperature in the furnace chamber does not suddenly drop even if the amount of combustion products in the furnace decreases, so that stable combustion efficiency can be maintained.

Since the outer wall of the furnace has a heat insulating property, the surface temperature can be maintained at such a level that the human body is not damaged even if it comes into contact with it.

Since the furnace wall has a structure capable of absorbing thermal shock and mechanical shock, it is possible to prevent cracking and breakage of the furnace wall.

Since the outer wall of the furnace does not rust, it does not spoil the aesthetics of the surroundings.

It is economical because it is easy to process and assemble, the cost required for it can be reduced, and mass production is possible.

By imparting conductivity to the fibrous member forming the buffer layer, it is possible to give heat generation and heat absorption to the furnace wall, so that it can be used in a furnace that handles huge heat such as a large incinerator and a blast furnace. .

When the shape-memory property is imparted to the fiber member forming the buffer layer, the furnace wall can be reinforced at a predetermined furnace temperature. The present invention has the above-mentioned remarkable effects and has a high industrial utility value.
