[0005]

To achieve this object, the incinerator of the present invention has the following constitution. That is, the incinerator according to claim 1 is a frame body composed of one or a plurality of layers of wire netting, and a metal plate or the like for fixing the periphery of the wire netting by welding or the like or sandwiching the end portions of the wire netting or the like. And a vent furnace wall provided with a perforated plate such as a metal plate, a ceramic plate, or a composite plate thereof having a large number of through holes formed of one to a plurality of layers. It has a structure provided on one furnace wall. The incinerator according to claim 2 is the incinerator according to claim 1, wherein the mesh of the wire mesh body of the ventilation furnace wall has 2.5 mesh to 60 mesh, and / or the wire diameter thereof is 1.5 mmφ to 0. It has a structure having 15 mmφ. The incinerator according to claim 3 is the incinerator according to claim 1, wherein the diameter of the perforated plate of the ventilation furnace wall is 1.5 mm to 20 mm.
It has the structure formed in. The incinerator according to claim 4 is the incinerator according to any one of claims 1 to 3, wherein a reflecting portion for incinerating heat made of a metal plate or the like is provided at least at a predetermined portion on the inner wall side of the ventilation furnace wall. Have a configuration. The incinerator according to claim 5 is the incinerator according to any one of claims 1 to 4, wherein an inlet for an incinerator opened in a ventilation furnace wall forming the furnace body and the inlet for opening and closing the inlet. And a lid portion for freely opening and closing the lid.
The incinerator according to claim 6 is a vent according to any one of claims 1 to 5, wherein each furnace wall around the furnace body is rotatably or detachably connected through a joining member. It has a structure formed by a furnace wall. The incinerator according to claim 7, wherein the furnace body is formed of a polygonal metal plate having a substantially isosceles trapezoidal shape or a substantially square shape, and one of an upper side portion, a lower side portion, or both side portions of the furnace wall. A plurality of substantially isosceles trapezoids that are detachably or rotatably connected to the above-mentioned side portions, or a plurality of polygonal shapes in which the intersection angle between the bottom side portion and the side side portion has at least one orthogonal portion. And a ventilation furnace wall according to any one of 5 to 5. The incinerator according to claim 8 is the incinerator according to any one of claims 1 to 7, wherein the grate is detachably disposed in the furnace body, and / or is disposed below the grate. And an ash receiver that has been removed.

Here, the wire mesh of the ventilation furnace wall has a mesh of 2.5 mesh to 60 mesh, preferably 12 mesh to 40 mesh, more preferably 12 mesh to 3 mesh.
0 mesh with a wire diameter of 1.5 mmφ to 0.15 mmφ, preferably 1.1 mmφ to 0.25 mmφ, and more preferably 1.
Those having a diameter of 02 mmφ to 0.304 mmφ are preferably used.
As the mesh size becomes larger than 30 mesh and the wire diameter becomes smaller as the wire diameter becomes smaller than 0.304 mmφ, the wire diameter becomes small, so it depends on the kind of combustible material (synthetic resin etc.). Generally, it tends to be oxidized by a flame and tends to lack durability, which is not preferable. As the material of the wire net body, austenitic stainless steel, high manganese steel stainless steel, and austenite-ferritic stainless steel are preferably used. This is because it has excellent heat resistance and resistance to residual stress. Although the number of the wire mesh may be one layer, it is preferable to stack two or more wire meshes because the secondary combustion efficiency can be increased and the mechanical strength of the furnace wall surface can be increased. In addition, when a plurality of sheets are stacked, the mesh may be increased as the number of stacked sheets increases, and when the number of layers is one or two,
It is preferably 12 mesh or more. By reducing the opening ratio of the mesh of the ventilation furnace wall, it is possible to enhance the secondary combustion effect and prevent ash from blowing out from the wire mesh body.

A steel plate sheet is preferably used as the frame surrounding the wire netting. As the material, the same material as the wire mesh body is preferably used from the viewpoint of durability and the like, and whether the circumference of the wire mesh body is welded from one side of the wire mesh body with a frame having a width of 2 mm to 100 mm, preferably 6 mm to 40 mm Alternatively, it is formed by sandwiching the end portions of the wire mesh body or further fixing the sandwiching portions with screws or the like. As the width becomes narrower than 6 mm, the welding strength, the sandwiching strength, etc. become insufficient, and the durability tends to decrease.
As the width becomes wider, it depends on the thickness of the steel sheet forming the frame and the size of the furnace wall, but the weight tends to increase and the transportability tends to be poor.

As another metal plate (for example, punch metal) of a perforated plate or a ceramic plate constituting the ventilation furnace wall,
The diameter of the through hole is 1 mm to 20 mm, preferably 2 mm to 7 mm. As the diameter of the through holes becomes smaller than 2 mm, the air permeability tends to be poor depending on the formation density of the through holes and the thickness of the metal plate, and as it becomes larger than 7 mm,
The secondary combustion efficiency in the through holes tends to decrease and the amount of smoke tends to increase, which is not preferable. As the material of the metal plate, the same material as the material of the steel plate sheet is preferably used.

The shape of the furnace wall around the furnace body is an isosceles triangle, a right triangle, a square such as a square or a rectangle, or an isosceles trapezoid. For isosceles triangles and quadrangular shapes, three or more ventilating furnace walls are provided with a connecting portion on each side wall portion and are connected to each other, and one ventilating furnace wall is made openable to be incinerated. It may be used as a charging port, or an opening may be formed in the wall of one ventilation furnace to serve as a charging port for the incineration product. It is desirable to form an opening / closing door at the charging port. This is to prevent blowing up of sparks. The furnace body is formed in an incinerator having a substantially pyramid shape or an upper pyramid shape and a lower part having a box shape. The entire furnace wall may be an aeration furnace wall, but a part of the furnace wall may be replaced with a metal plate, a ceramic plate, a ceramic-coated metal plate, or the like. Furthermore, a part or part of the ventilation furnace wall may be replaced with a metal plate or the like to form a reflection part for incineration heat. By providing the reflecting portion on a part of the ventilation furnace wall, the combustion efficiency of the incinerated material can be increased by the reflected heat of the radiant heat and the incinerated heat. The reflective portion is formed with 40% or less of the area of the furnace wall, preferably 20% or less. This is to ensure breathability. In addition, the surface strength of the ventilation furnace wall can be reinforced by providing a reflecting portion or the like.

When forming the top plate portion, it is preferable to use the ventilation furnace wall such as the wire mesh body or the perforated plate as the top plate,
In addition to the wire net body, a metal plate or a ceramic plate may be used.
This is because the combustion efficiency is increased by the radiant heat and the reflected heat. As the connecting portion, hinges, hooks, hanging fittings, bolts and nuts, clippers, and other known fasteners are used.

[0011]

With this construction, at least the entire or part of the surrounding furnace wall is formed by the aerated furnace wall, so that the air permeability is remarkably excellent, the combustion speed is extremely high, and the incineration workability can be improved. Since the combustibility is extremely high, the amount of smoke generated can be suppressed. Further, since the wire mesh body and the perforated plate of the ventilation furnace wall are red-hot due to a strong flame, it is possible to secondarily burn smoke and incompletely combusted gas, and substantially completely oxidize and decompose it to eliminate smoke. Further, since the mesh and the hole diameter of the ventilation furnace wall are small, it is possible to prevent the ash from being blown to the outside, which is excellent in fire prevention and can prevent the work environment from being contaminated. Since the flame loses heat when passing through the wire mesh of the ventilation furnace wall, it prevents the flame from blowing out from the ventilation furnace wall, and since it falls below the ignition temperature of the outside air flow like the safety light of Wolf, it is a transitional fire. Etc. can be prevented and the safety can be remarkably enhanced. Since the furnace wall is connected at the connecting part so that the surroundings can be detached or folded,
It is possible to freely disassemble / assemble or fold / assemble by removing the connecting part or bending at the connecting part. When a furnace wall made of a metal plate or the like is partially used or a reflecting portion is provided, combustion efficiency can be improved while maintaining air permeability by the radiant heat or reflected heat.

As shown in FIG. 1, the incinerator 1 in which the respective oven walls are alternately bent and folded is assembled as shown in FIG. When there are many incinerated materials, the ventilation furnace wall 4a on the front side is opened as shown in FIG. Next, the ventilation furnace wall 4a
Is closed, the input port lid part 7 is opened, and fired paper waste is input into the incinerator 1 through the input port part 6. Ventilation furnace wall 4 around the entire circumference of the furnace body
Since it is made of wire mesh, air enters from the entire circumference and it has excellent breathability, and the flame spreads all over the incineration at a stretch, and the air is further sucked from each ventilation furnace wall 4 by the upward flow due to the burning flame, so the combustion Since the inside of the furnace has a high temperature and the ventilation furnace walls 4a, 4b, ... Are made of metal, it reflects heat and absorbs the heat of the flame to generate radiant heat, which further increases the temperature inside the furnace, resulting in moisture. It is possible to incinerate kitchen garbage, which is often used. In addition, since the shape of the furnace body is a quadrangular pyramid, air is sufficiently supplied and the draft effect is high, so even if a tray made of synthetic resin is burned, complete combustion will occur and thin smoke will be recognized in the furnace, but this thin Smoke also ventilated furnace walls 4a, 4b ...
Is heated to a high temperature, it is possible to be secondarily combusted when passing through the wire netting of the ventilation furnace wall, and almost smokeless. The flame at the time of incineration is deprived of heat when passing through the wire mesh on the ventilation furnace wall, and is cooled to a temperature below the ignition temperature of the outside airflow like a safety light of Wolf. Therefore, the ventilation furnace wall does not blow out a flame to the outside and can prevent the transfer fire. Since the mesh of the wire mesh on the ventilation furnace wall is small, it is possible to prevent the leakage of sparks. After the incineration, the ventilation furnace wall is made of wire mesh and has a high thermal conductivity, so that it is cooled in a short time, and even if the ventilation furnace wall 4a on the front side is opened, there is no risk of burns. Drop the ash into the ash container 11. Next, the connecting portions 5a and 5b are removed, and the connecting portion 5c is folded as shown in FIG. 4 and stored in a warehouse or the like. Although the folding type is described in the present embodiment, it may be a disassembling type.
In this case, the connecting portion 5c can be easily achieved by using a detachable hanging metal fitting.

As described above, according to the present embodiment, the shape is substantially a quadrangular pyramid, the air permeability is excellent, and the draft effect is high, so that even a flame-retardant material can be completely burned. In particular, it has been found that large lumps of combustible materials such as wood chips discharged at construction sites and civil engineering sites can be easily ashed in a short time. Also, since the incinerator can be assembled freely, it can be stored in a small space, and can be easily transported to the site, which is excellent in storability and transportability. Especially in civil engineering work and construction sites, waste materials have been brought back for incineration.
According to the incinerator of this example, even if it is incinerated, it does not emit flames or powders, there is no danger of fire and it is excellent in safety, so incineration can be performed on site, especially in remote areas such as mountains. It is possible to significantly improve the workability of post-processing work such as construction work on site.

The incinerator 70 of the fifth embodiment differs from the incinerator of the fourth embodiment shown in FIGS. 9 and 10 in that a top plate portion 71 made of a metal plate is rotated on the rear side wall 60 via a rotating portion 72. The top plate 71 has a smoke stack support 73 for holding a smoke stack 74 in the center, and the top plate 71 has a front inclined furnace wall 75 made of one or a plurality of wire mesh members and a rotating part 76. The point is that they are rotatably connected in series. Since the incinerator of the fifth embodiment is configured as described above, it is possible to reflect the flame by the top plate portion 71 and raise the temperature inside by radiant heat.
Further, since the smoke cylinder 74 is provided, the combustion efficiency can be remarkably improved due to the strong draft effect in combination with the wire mesh of the surrounding ventilation furnace wall.

Since the present invention is constructed as described above, it is possible to realize an incinerator having the following excellent effects. a. Since at least one of the furnace walls around the incinerator is formed by a ventilation furnace wall made of a wire netting or a perforated plate, it has excellent air permeability and can perform a large amount of incineration treatment in a short time. b. When smoke and volatile components pass through the ventilation furnace wall, the mesh of the wire netting and the hole diameter of the perforated plate are small, and secondary heat is generated by the radiant heat, so that almost no odor and no smoke can be achieved. c. Since the ventilation furnace wall is made of metal or ceramic, the temperature inside the furnace is raised by reflected heat or radiant heat, so that the combustion efficiency can be further improved. d. Since the ventilation furnace wall is a wire mesh or a perforated plate, ash does not scatter even if the wind blows, preventing fire and polluting the work environment, and it is excellent in safety and workability. e. Since the ventilation furnace wall has a mesh of meshes and a small hole diameter of the perforated plate, it is possible to prevent the flame from being blown out from the meshes like the safety light of Wolf and it is excellent in safety. f. When a metal plate is combined with the ventilation furnace wall or when a metal plate or the like is installed on a part of the furnace wall, the combustion efficiency can be further improved by the reflected heat and the radiant heat of the metal plate. g. Since it can be folded, disassembled and assembled freely, the whole is compact and does not take up space when storing or moving,
It has excellent storability and transportability.
