Abstract

PURPOSE:To make skilled technique unnecessary at all, require no complicated mold frame, permit efficient works regardless of the size and/or configuration, permit the expansion and/or contraction of a volume and the like easily and save a cost largely as result. CONSTITUTION:A flange 2 for connection is attached to the outer surface of a heat insulating casing member 1 and anchor members are attached to the inside of the same member 1, then, mold frame is assembled at the inside of the heat insulating casing member 1 to place refractory material 6 and form a segment 7 while the flanges for connection 2 of the segment 7 are connected and fixed sequentially.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an incinerator, and more particularly to an incinerator for incinerating industrial waste, and to a novel method for constructing the furnace wall.

[0002]

2. Description of the Related Art Conventionally, in the construction of a furnace wall of an incinerator described above, generally, an outer casing is assembled, and refractory bricks are piled up and fixed to the inner surface of the outer casing, or an irregular refractory is driven by forming a formwork. In some cases, there is also adopted a method in which only an irregular refractory material is molded as a block and the block is assembled to the outer casing using bolts or the like.

[0003]

However, according to the above-mentioned conventional construction method, when using refractory bricks, skilled skill of brickworking is required, and no one can execute it. In the case of refractory materials, a large-scale formwork is required depending on the shape and scale, and all of them are expensive, so refractory construction is limited to the installation site. Further, in the case of a cylindrical or other deformation furnace, the labor and cost are increased as compared with the rectangular one.

[0004]

SUMMARY OF THE INVENTION Therefore, the present invention has been made by paying attention to the problems of the prior arts described above, and it is necessary to solve the problems, to eliminate the need for skilled skill and to form a large formwork. A method of constructing a furnace wall of an incinerator that can be efficiently constructed regardless of size and shape, can be easily expanded and contracted in volume, and can greatly reduce costs, even if it is not. Is intended.

[0005]

In order to achieve this object, in the method of constructing the furnace wall of the incinerator according to the present invention, a flange for connection is attached to the outer surface of the heat insulating casing material, and an anchor member is attached to the inside. After that, a mold is assembled on the inner side of the heat insulating casing material, a refractory material is driven in to form a segment, and the connecting flanges of the segment are sequentially connected and fixed.

[0006]

With the above-mentioned structure, the construction of the furnace wall can be speeded up efficiently, and it can be completed without any special skill, so that the cost can be greatly reduced and the construction can be achieved. The construction does not depend on the size or shape, and the complexity at the installation site is eliminated.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will now be described with reference to the drawings. FIG. 1 is a sectional view showing a part of a furnace wall constructed by carrying out the present invention.

In FIG. 1, reference numeral 1.1 indicates a casing material made of a heat insulating material. In the present embodiment, each of the heat insulating casing materials 1 is formed as a flat plate, and it is planned to construct a rectangular incinerator, but in the case of a cylindrical incinerator, the furnace wall It may be bent in an arc shape to form a part.

A connecting flange 2.2 is fixed to one side surface which is an outer surface of the above-mentioned heat insulating casing material 1.1.
The connecting flanges 2.2 are provided with upper and lower connecting bolt insertion holes 3 ... and brackets 4 ... That fasten the adjacent connecting flanges 2.2.

Further, the above-mentioned heat insulating casing material 1.1
Y studs 5, 5 as anchor members on the inner surface of the
A plurality of ... Are embedded and fixed at the base. After that, a mold is assembled on the inner surface side, and the irregular shaped refractory 6.6 is placed in the state where the Y studs 5 and 5 are embedded, and if necessary, vibration is applied to achieve the denseness. To be

The segments 7 and 7 are formed in this manner. The segments 7 and 7 have different contact strengths between adjacent ones and the widths of the above-mentioned irregular-shaped refractories 6 and 6 are changed in order to prevent positional displacement. Is configured in a stepped shape.

The above-described molding of the segments 7 and 7 can be sufficiently performed not only at the installation site but also at the factory, and the molded segments 7 and 7 can be transported to the installation site and only assembled there. It will be possible. This assembly is performed by fastening the above-mentioned connecting flanges 2.2 or brackets 4, 4, ... Using bolts 8 etc., but an expansion margin due to heat is secured between the contact surfaces of each segment 7, 7. Therefore, the heat-resistant cushion material 9 is sandwiched.

The method for constructing the furnace wall of the incinerator according to the present embodiment is constructed as described above, and it is similarly executed even in the case of a cylindrical incinerator or the size difference.
Further, in this embodiment, the Y stud 5
Although 5 is used, it goes without saying that other members can be used without being particular to this, and the unit size of each segment 7, 7 ... Is not limited.

[0014]

The method for constructing the furnace wall of the incinerator according to the present invention is configured as described above. Since it is constructed by a segment that integrates an insulative casing material with an irregular shaped refractory and a connecting flange, no skill is required, and a large formwork is not required, and repeated use is possible. Also,
Repairs can be performed for each segment, the scale can be easily changed, and quality control can be performed with high accuracy. Further, since only assembling is required at the installation location, efficient segmentation at a factory or the like can be facilitated, and transportation and assembling work can be facilitated, resulting in a large reduction in overall cost. Furthermore, it is easy to dismantle the product after its useful life has passed.
