Furnace. Further, the incinerator device has a simple structure of the furnace main body, can be easily moved and installed, and can be used indoors as a fireplace.

The incinerator body has an outer cylinder having an exhaust port at the upper part and an open lower part, a bottomed inner cylinder attached so as to provide a circumferentially spaced gap inside the outer cylinder,
It is preferable that the outer cylinder has a ventilating exhaust port at the upper part and the entire lower part is open. At the bottom, the air supply hole for supplying outside air is large and easy to secure evenly, and the inner cylinder performs the function of guiding outside air from the air supply hole, and furthermore, the attachment and detachment of the inner cylinder and the outer cylinder However, the convenience of installation, construction such as transportation, storage, installation, and removal is high. The upper part may be formed in a cylindrical body narrowed toward the exhaust port. Specifically, if the funnel-shaped umbrella whose center is open is turned upside down and put on the top of the outer cylinder and locked,
The uniform burning action inside the incineration chamber is ensured, and the cylindrical part and the shade part can be manufactured in a divided state, and can be assembled and used, so the outer cylinder can be easily formed and the manufacturing cost is low, Moreover, it is convenient for transportation, loading, storage and the like.

The bottomed inner cylinder is slightly smaller than the outer cylinder, and is preferably a cylindrical body having a bottom which is entirely open and has high fire resistance, for example, a bottom made of fire brick or concrete. Various incineration materials are put into the bottomed inner cylinder and incinerated. In addition, if the bottom portion of the inner cylinder is provided with legs to keep the bottom surface floating, the lower opening of the outer cylinder is not closed, so that a large amount of outside air is introduced from the lower opening. If an opening for ashes is provided in a part of the lower part of the bottomed inner cylinder, the ashes after garbage incineration can be easily performed. It is preferable that the outer cylinder and the bottomed inner cylinder be formed in a circular shape in a plan view from a heat-resistant steel plate or the like because it is easy to manufacture, but the material and dimensions are not limited to this, and any shape such as a polygon can be used. May be formed.

The incinerator body is composed of the above-mentioned outer cylinder and bottomed inner cylinder. The incinerator body is covered with the bottomed inner cylinder installed on the ground or the like so that the lower opening of the outer cylinder is inserted from above. Contains a bottomed inner cylinder. Then, an incineration chamber is formed inside the incinerator body, and an incineration airflow generated when incineration dust is burned is exhausted from an exhaust port at an upper portion of the outer cylinder. At this time, it is important that a separation gap is provided circumferentially inside the outer cylinder, and the outside air is supplied to the incineration chamber inside the incinerator body while flowing through the gap. Since the gap is easy to form and has a simple structure, the manufacturing cost of the incinerator body is kept low.

In other words, the upper portion of the gap communicates with the incinerator and the lower portion communicates with the outside air, so that the inner cylinder is double-walled inside the outer cylinder. The air is supplied to the inside of the incineration chamber while flowing from the gap so that the outside air is sucked up by the negative pressure. Therefore, not only is a large amount supplied to the incineration chamber from the gap formed in the outer periphery of the bottomed inner cylinder, but also is supplied evenly into the incineration chamber. There is no need to provide a power unit or the like.

A plurality of openings communicating with the gap are formed in the peripheral wall of the bottomed inner cylinder, and a portion of the outside air flowing through the gap is efficiently supplied into the bottomed inner cylinder. It is desirable that the holes are arranged so as to be scattered over the entire peripheral wall, and the opening should be large enough to have air permeability and to prevent incineration dust from jumping into the gap. For example, the peripheral wall may be formed by simply perforating a polygonal or circular shape, or a V-shaped cut may be made in the peripheral wall and the top portion thereof may be extruded outward to provide high air permeability along the flow of the outside air. An opening is formed. The openings may be arranged at arbitrary intervals on the peripheral wall of the inner cylinder, and the shape of the openings may be arbitrarily formed as long as the outside air can be sufficiently supplied into the incinerator.

A straight pipe having a rostral rod radially provided therein is provided vertically in the bottomed inner cylinder, and receives incineration refuse introduced into the incineration chamber from an input port above the incineration refuse to burn the refuse. The refuse can be efficiently burned while dropping the residue downward from the gap between the rostral rods that spread radially. The upper surface of the straight pipe communicates with the incineration chamber, and the lower surface of the straight pipe communicates with the outside air. It is supplied directly to the room to completely burn incineration waste. It is preferable that the straight pipe pipe is fixed by penetrating the bottom with high fire resistance because the supporting strength is secured, and one end upper part of the hollow straight pipe pipe is in the incinerator and one end lower part is in the bottom of the bottomed inner cylinder. It is open.

The incinerator body has a charging opening at least above the height of the bottomed inner cylinder, and the upper part of the bottomed inner cylinder is secured as a charging opening through which incineration dust can pass. From here, incineration waste etc. is put into the incineration chamber. As the shape of the opening, it is preferable that the opening is in the form of a vertically elongated rectangle from the vicinity of the upper end of the incinerator body side, and if it is provided to the vicinity of the lower end of the incinerator body, ash removal after incineration becomes possible from here. . The present invention is not limited to this, and an input opening and an ash-like opening through which incineration dust can pass may be separately provided.

A door which is detachably and freely openably and closably attached to the input opening is mounted. The door is opened when dust is input, dust is input from the opening, and when incinerated, the opening is closed to close the opening. It is possible to put. It is only necessary that the opening can be freely opened and closed, and the size of the door can be arbitrarily formed in accordance with the opening. Also, the door body can be used as an open opening that is disengaged from the incinerator body and in this case, the incinerator device can be installed indoors and used as a fireplace while using it as an incinerator. is there. That is, for example, a heating effect can be obtained indoors by the heat generated by incinerating while incinerating garbage as needed.

A combustion cylinder is provided above the exhaust port of the incinerator so as to form a combustion chamber communicating with the flue.
The incineration airflow exhausted from the exhaust port of the incinerator body can be completely burned in the combustion cylinder and exhausted to the flue. That is, since the combustion auxiliary plate is provided in the combustion cylinder and located at a position separated upward from the exhaust port and having a surface that intersects with the flow of the incineration airflow from the incineration chamber,
The incineration airflow that rises from the exhaust port of the incinerator into the combustion cylinder collides with the intersecting surface of the auxiliary combustion plate, causing turbulence and promoting secondary combustion. At this time, the outside air is taken in from the outside air intake opening provided at a position lower than the combustion auxiliary plate, and efficiently mixed with the turbulent incineration airflow to completely burn the unburned gas,
May reduce smoke and soot. Thus, even if the incinerator device is installed indoors, it does not pollute the air and can be used as an incinerator that can be used as a fireplace.

The combustion cylinder is connected so as to communicate with the flue on the inverted upper surface side, and can flow through a flue, for example, a tubular chimney, to naturally exhaust the incineration airflow into the outside air. If this chimney is detachable on the upper surface side, it can be easily assembled even on site. The combustion cylinder is formed in a cylindrical shape, and the large opening on the lower surface side covers the upper exhaust port of the incinerator body. Is locked in the same manner. Since the outside air intake opening is formed as a circumferential air supply opening for circumferentially communicating the combustion chamber with the outside air, the outside air is efficiently supplied in large amounts from the surroundings while being mixed with the flow of the incineration airflow. The peripheral air supply opening is formed in the shape of a donut by the size of the opening on the lower surface side that is larger than the exhaust port. preferable.

A water receiving / draining portion for collecting and discharging water entering the incineration cylinder is provided on the periphery of the exhaust port, so that rainwater containing dust soaked in from a flue or the like drops. It is possible to discharge to the outside of the incinerator body, and since the outer periphery of the incinerator body is not stained by raindrops or the like, the appearance is maintained.
Further, since the incinerator body is protected from corrosion due to oxidation, the durability is maintained for a long time, and the repair cost can be reduced. Specifically, it is preferable to provide a collar, for example, in the form of a collar around the upper exhaust port periphery of the incinerator body, so that it is easy to attach it.Water accumulates in the formed inner groove. If one end is connected outside the incinerator body, water can be discharged through the pipe. In addition, a U-shaped drain groove other than the pipe pipe may be provided so as to be able to drain outward.

In other words, the incinerator body can be disassembled into an outer cylinder and a bottomed inner cylinder, and can be easily transported as a single unit in a lightweight state, and can be easily assembled and moved on site or in a factory. It is possible to easily perform maintenance and inspection of the inside and replace it as a repair unit. Furthermore, the outer cylinder and the inner cylinder of the incinerator body are cooled by the outside air passing through the gap, so that the heat resistance of the incinerator body can be increased and the durability can be maintained.

A combustion cylinder is provided above the exhaust port of the incinerator body so as to form a combustion chamber leading to a flue.
A combustion auxiliary plate is provided in the combustion cylinder, and is located at a position separated upward from the exhaust port and has a surface that intersects with the flow of the incineration airflow from the incineration chamber. By providing an outside air intake opening at a position lower than the plate, the combustion or incineration airflow rising into the combustion cylinder from the upper exhaust port of the incinerator body collides with the combustion auxiliary plate to form a turbulent flow, and a primary stagnation state, In this state, by further supplying oxygen from the outside air intake opening, secondary combustion is performed at a high combustion temperature in the combustion cylinder, and the incineration can be completely incinerated. This also makes it possible to reduce smoke, soot and toxic components in exhaust gas. In addition, rainwater that enters from the flue etc. and drops is received by the combustion auxiliary plate at any time, flows outside the exhaust port, and the incineration chamber is always kept in a dry state suitable for combustion to burn garbage even in rainy weather. Enable.

Further, the combustion cylinder is formed in an inverted cup shape in which the inverted upper surface side is connected to the flue and the inverted lower surface side is opened larger than the exhaust port. Is formed as a circumferential air supply opening for circumferentially communicating the combustion chamber and the outside air, so that an outside air intake opening is formed in a circumferential shape, and the outside air is taken in from all circumferential directions, whereby The air is supplied to the turbulent incineration air stream and mixed efficiently to completely combust the unburned gas contained in the exhaust stream to reduce smoke and soot. Can also be used.

Further, the incinerator body has a charging opening provided at least above the height of the bottomed inner cylinder,
A door body which is detachably attached to the charging opening and which is openably and closably mounted is mounted, so that the door body can be opened and closed, and incineration garbage can be thrown into the incinerator through the charging opening, and used as an incinerator. It can be used as an incinerator that can also be used as a fireplace while being installed indoors, removing the door, and injecting incinerated garbage, waste materials, and other combustibles from the opening as needed.

Further, a water receiving / draining portion for collecting and discharging water entering the incineration cylinder is provided on the periphery of the exhaust port, so that the combustion auxiliary plate allows the water to flow outside the exhaust port. The collected incinerator body receives rainwater containing dust and discharges the water so as not to be transmitted down the outer periphery of the incinerator body, so that the appearance of the incinerator body can be maintained without being stained with raindrops. Further, the incinerator body is protected from corrosion, and the maintenance cost of the incinerator is maintained at a low price for a long time.

Further, a plurality of openings communicating with the gap are formed in the peripheral wall of the bottomed inner cylinder, so that the combustion air flows from the gap through the plurality of openings of the inner cylinder peripheral wall in the incineration chamber. By uniformly supplying oxygen from around the incineration waste, the incineration waste can be efficiently burned.

Further, a straight pipe pipe having a rostral rod radially provided therein is provided vertically in the bottomed inner cylinder, and an upper surface of the straight pipe pipe communicates with the incineration chamber, and a lower face thereof is connected to outside air. Combustion state of garbage by functioning as a Rostor rod while simultaneously flowing air for combustion through the straight pipe tube and supplying oxygen directly to the burning central part of the incineration chamber Can be optimally maintained.
