Field of the Invention The present invention relates to an incinerator of an assembling type which is most suitable for use at home, and more particularly to an incinerator of an assembling type which can easily connect and disassemble a side wall forming block in a vertical direction.

[0002]

2. Description of the Related Art Conventionally, many incinerators used in homes are made of iron plate. However, combustion heat is added to air oxidation and rust progresses rapidly. Since it is high, it has various drawbacks such as a very high possibility of burns and nearby ignition.

[0003]

To solve such disadvantages, an incinerator made by assembling concrete blocks, bricks and the like is disclosed in, for example, Japanese Patent Application Laid-Open No. 2-157507. Already developed.

In this incinerator, as a means for vertically connecting the side wall forming block, a vertical hole penetrating up and down is formed in the block. The upper end of the gripping member, which is penetrated so as to be able to protrude and retract in the vertical direction so as to be able to protrude and retract in the vertical direction, and protrudes upward from the insertion hole formed on the upper surface of the vertical hole of the block installed in the lower stage, It is configured to be fitted into an insertion hole formed on the lower surface of the vertical hole of the installed block.

[0005] As a result, the upper and lower blocks are connected via the gripping members. However, through vertical holes having insertion holes on both upper and lower surfaces are formed, and the gripping members are bent.
Various processes such as insertion and assembling of the gripping member into the vertical hole are required, and at the same time, a gripping member that has been subjected to a bending process is required. There is a point.

The upper and lower surfaces of the corner block 3 are formed with arc-shaped or cylindrical concave portions 5 and 5, respectively, at mutually facing surface contact portions.
For example, the space 6 formed by
Is a circular shape, the connecting member 7 made of a metal sphere 7A as shown in FIG. 7 is used. If the space 6 is a box-shaped one, a connecting member 7 is made of a cylindrical body 7B as shown in FIG. Each of the connecting members 7 intervenes, and the connecting members 7 prevent positioning of the upper and lower corner blocks 3 and 3 and prevent vertical connection and horizontal sliding.

That is, in the vertical connecting method, the first-stage side wall portion is formed by abutting an L-shaped corner block 3 and an intermediate block 8 to be described later, and an arc-shaped portion formed on the upper surface of the corner block 3 The sphere 7A or the columnar body 7B as a connecting member is dropped into the cylindrical concave portion 5.
Next, the second-stage corner block 3 is placed on the corner block 3 and is slid in the horizontal direction, so that the concave portion 5 formed on the lower surface thereof is fitted into the upwardly projecting portion of the spherical body 7A or the cylindrical body 7B. By connecting.

Reference numeral 8 denotes a cubic intermediate block installed between the corner blocks 3 and 3, which is formed of porous concrete similarly to the corner block 3, and has two types of a long intermediate block 8A and a short intermediate block 8B. It is composed of And, at the bottom, bottom plate 2
The inside wall of the upper flange 2A, the intermediate block 8 is sequentially stacked thereon to form a side wall main body 4B having a desired height, and the side wall main body 4B and the corner side wall 4A as a whole form The side wall part 4 of a square tube shape is formed.

The corner block 3 and the intermediate block 8
End faces 3A, 8C and intermediate block 8 in the lateral direction with
Although not shown, interlocking concavo-convex portions or corrugated concavo-convex portions are respectively formed on the horizontal joining end faces 8C of the competitors, and the connection in the horizontal direction of the same step requires the concavo-convex portions to be fitted to each other. This prevents the intermediate block 8 to be joined from being positioned in the lateral direction and prevents the side wall 4 from sliding in and out (in the horizontal direction).

Reference numeral 9 denotes a top plate for closing the upper opening of the rectangular cylindrical side wall portion 4. The top plate 9 is made of fire-resistant concrete made of alumina cement, which has the highest fire and heat. Is formed. Reference numeral 10 denotes a dust inlet formed at a position near one side of the top plate 9, and a cylindrical portion 11 for attaching a chimney is integrally formed at a position near one edge on the rear side in a protruding state. I have. And the trash input port 10
A lid 12 with a handle 12A is attached so as to be detachable, and a lower end of a chimney 13 is inserted into the cylindrical portion 11, and is fixed by tightening with a band from above.

14A is a ventilation port and a residual ash removal port.
As shown in FIG. 3, when the U-shaped opening forming member 14 made of metal is installed in the notch 2B of the bottom plate 2, as shown in FIG. This is formed by disposing the intermediate block 8 between the three. Reference numerals 14B, 14B denote outer flanges formed on both side edges of the opening forming member 14, and intermediate portions of the side ends 3B of the corner blocks 3, 3 from the bottom to the second stage and the third stage shown in FIG. The lower surface 8D of the block 8 is fitted between the outer flanges 14B. In the figure, reference numeral 15 denotes a metal grate.

Reference numeral 16 denotes a gap for air supply, which is formed on each of the right and left and rear side walls 4 of the side wall 4, and in the illustrated embodiment, between the blocks 3 and 8 from the bottom to the second stage. It is provided. By forming the gap 16, the stable supply of oxygen into the incinerator 1 can be constantly performed without being affected by the direction and strength of the wind. Since stress concentration can be avoided, the durability of each of the blocks 3 and 8 and the durability of the incinerator 1 are improved.

[0016]

As described above, the assembling type incinerator according to the present invention is composed of the L-shaped corner block and the cubic intermediate block, and the horizontal direction between the corner block and the intermediate block in each stage. Is a connection structure by interlocking or fitting of unevenness, and the vertical connection is to form an arc-shaped or rectangular cylindrical concave portion on each of the opposed joint surfaces of the corner block. As a connecting structure in which a connecting member made of a sphere or a column is inserted into a space extending over both the upper and lower steps, a side wall is constructed by connecting the corner block and the intermediate block in the horizontal and vertical directions, The lower part of the side wall is equipped with a ventilation and ash removal port, and the upper part of the side wall is equipped with a top plate equipped with a garbage inlet and a chimney mounting part. Ri, yet assembled and disassembled can also be easily performed by amateur, structure after assembly also robust. Further, by providing a gap for air supply between the blocks at the lower part of the side wall, it is possible to always supply a stable supply of oxygen into the incinerator without being affected by the direction and strength of the wind. When the combustion condition is improved, stress concentration due to high temperature can be avoided, so that the durability of each block and the durability of the incinerator are improved. Furthermore, each block is made of porous concrete without using fire-resistant concrete or fire-resistant bricks whose manufacturing process is complicated and the raw material is high, so that expansion due to heat can be reduced and deterioration such as cracks due to combustion can be prevented. Can,
It can be provided at low cost while improving durability and fire resistance. There are various effects.
