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 suitable for incinerating household articles such as books, magazines and plastics.

[0002]

2. Description of the Related Art Generally, a medium-scale incinerator installed in a business establishment or a public facility is provided with an incinerator inlet on the upper surface or side surface of a rectangular parallelepiped furnace body composed of bricks or blocks. The incinerator charged through the charging port is configured to be mixed and burned while forcibly supplying oxygen in the outside air. In this case, the oxygen required for combustion is the ash outlet (also serves as the air intake) provided at the bottom of the furnace body.
The outside air is sucked in from the outside and is replenished through the bottom of the furnace body.

In the incinerator having such a structure, the incinerated substances such as paper, wood, plastic, etc. are first vaporized or liquefied by the heat in the oven, and are mixed with air and burned. ing. In addition, small-scale incinerators for garbage disposal installed in condominiums and the like are slightly different in that the furnace body is made of a metal cylindrical body and is compact,
The combustion mechanism is the same as in a rectangular incinerator.

[0004]

The above conventional incinerator has the following problems.
Air intake tends to be over or under,
It had a drawback that the temperature in the furnace did not rise sufficiently and did not reach complete combustion. This phenomenon is considered to occur by the following mechanism. The materials to be incinerated from the charging port spread like a face plate in the furnace and accumulate in a state like an "inner lid", shielding the air supplied from the lower side of the grate and creating an oxygen-deficient state. Will end up. In order to prevent air shortage, the air intake is made too large compared to the normal amount of the burned material, and the cooling action due to air inflow cannot be ignored.

As a result of such excess or deficiency of air, for example,
When a wet book or magazine is burned, the core may be left unburned due to insufficient temperature rise. This invention
It is an object of the present invention to provide an incinerator inner pot capable of eliminating such an imbalance in air supply and completely burning a material to be burned.

[0006]

In order to achieve the above object, the incinerator inner pot of the present invention is provided with a ventilation passage at an appropriate position of a cylindrical body which is in close contact with the inner wall surface of the furnace body, facing the inner wall surface. The folding curved surface to be formed is provided, and an appropriate number of air holes are provided in the folding curved surface so that the air can be stably supplied without excess or deficiency.

Further, the cylindrical body corresponds to a furnace body having a rectangular cross section, and the bent surface is provided so as to face each corner portion of the furnace body, and the corner portion is ventilated. By using it for roads, a high-efficiency inner pot suitable for a medium-scale incinerator can be constructed.

[0008]

When a material to be incinerated such as paper, wood, or plastic is introduced through the charging port, the material to be incinerated spreads and accumulates in a face plate shape in the furnace. As a result, the air supply from the lower side of the grate is temporarily insufficient, but the air supply from the air holes of the multiple air passages formed by the inner wall surface of the furnace body and the folded curved surface of the inner pot facing each other. Is uninterrupted. Therefore, the combustion in the furnace can be continued without interruption, and the temperature rise and smokeless combustion due to complete combustion are promoted.
