Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a simple incinerator used for incinerating combustible waste such as kitchen garbage in general households, factories, shops, schools and the like.

[0002]

[Prior art]

 Conventionally used incinerators generally consist of a cylindrical combustion chamber and a chimney provided on the lid of the combustion chamber, and a grate is placed in the lower part of the combustion chamber. Then, an ignition port that opens above the roster and an air intake port that opens below the rostrut are formed in the lower part of the combustion chamber, and the lid of the combustion chamber is half opened to serve as a dust inlet.

[0003]

[Problems to be solved by the device]

 In the above-mentioned conventional incinerator, the lid is opened and dust is put in, and then the ignition port is opened to ignite and incinerate, so the dust burns from the bottom. Therefore, when a large amount of dust is pushed in and burned, there is not enough space in the dust to not only burn well, but also a large amount of colored, odorous and harmful incomplete combustion gas is generated. become. Therefore, in the conventional incinerator, a large amount of dust cannot be incinerated at one time, the incineration time is slow, the incineration efficiency is poor, and harmful gas may be generated. In addition, in the case of conventional incinerators, it is not uncommon to use auxiliary fuel to increase the combustion power. Therefore, an object of the present invention is to provide an incinerator capable of completely and quickly incinerating a large amount of dust without generating harmful gas and without using auxiliary fuel.

[0004]

[Means for Solving the Problems]

 According to the present invention, a bottom grate is arranged in the lower part of the combustion chamber, a vertical grate is installed upright in the central part of the bottom grate, and an ignition port and an air intake opening below the bottom grate are formed in the lower part of the combustion chamber. The above problem is solved by an incinerator having a chimney provided on the upper surface of the combustion chamber and having a lid that can be fully or partially opened attached to the upper surface of the combustion chamber. Preferably, a combustion suppressing cylinder is attached to the upper end of the vertical rostrul, and the diameter of the chimney with respect to the lid is wider than that of the vertical rostrul, and the re-combustion has a metal mesh layer inside. Intervene in the chamber.

[0005]

[Work]

 Since there is a vertical gust that serves as a combustion tube in the center, dust burns well from the inside, and incompletely burned gas reburns in the heated vertical grate. When the re-combustion chamber is provided, the metal mesh layer is heated within a short time after the start of combustion, so the incomplete combustion gas that could not be recombusted in the vertical loss is re-combusted there, and It becomes pollution gas and is discharged from the chimney.

【Example】

 A preferred embodiment of the present invention will be described with reference to the accompanying drawings. FIG. 1 is a partial sectional front view of an incinerator according to the present invention, FIG. 2 (a) is a plan view of a grate, and FIG. 2 (b) is a partial sectional front view thereof. In the figure, 1 is a metal combustion chamber similar to the conventional one, which is usually cylindrical. On the inner bottom of the combustion chamber 1, there is usually provided a bottom part strut 2 in which a large number of heat-resistant rods are radially arranged and the ends thereof are bent downward along the inner surface of the combustion chamber 1. It The central portion of the bottom portion 2 is recessed to form a shallow mortar shape.

At the center of the bottom grate 2, a vertical grate 3 is installed. The vertical rod 3 is made by arranging rod members similar to the above in a circular shape and standing upright, and the supporting member 4 is appropriately fixed to the inside or outside thereof and the cylindrical state thereof is maintained. The vertical rostrum 3 may be a porous oblong cylinder. Preferably, a combustion suppressing cylinder 5 is fitted on the upper end portion of the vertical rustle 3.

At the lower end of the combustion chamber 1, an openable ignition port 6 that opens to the lower surface side of the bottom loss 2 is installed, and preferably one or more air intakes 7 whose opening can be adjusted. Is installed. The ignition port 6 also serves as an outlet for the ash accumulated under the bottom roster 2. The upper surface of the combustion chamber 1 is covered with a lid 8 on which a chimney 10 is installed via a re-combustion chamber 9. The lid 8 may be a fully open type or a half open type.

The re-combustion chamber 9 is wider than the vertical rustle 3, and a combustion suppressing cylinder fitting portion 11 extending downward is formed in the lower surface opening thereof, and the upper end portion of the combustion suppressing cylinder 5 is fitted therein. To be done. Normally, this re-combustion chamber 9 is integrated with the lower end of the chimney 10. Reference numeral 12 is a metal mesh layer such as a thin iron wire provided from the upper part of the re-combustion chamber 9 to the lower part of the chimney 10.

In using the incinerator according to the present invention having the above-mentioned structure, the lid 8 is opened and dust is put into the combustion chamber 1. However, unlike the conventional incinerator, a large amount of dust may be pushed in. Absent. After closing the lid 8 and inserting an old newspaper or the like from the ignition port 6 to ignite, the dust is burned to the dust contacting around the vertical lostl 3, and the dust is burned from the inside. Therefore, the outer side surface of the combustion chamber 1 does not become so hot, so it is not dangerous. Since the air taken in from the air intake 7 flows into the vertical rostrur 3, the dust around the vertical rostrur 3 burns well.

A combustion suppressing cylinder 5 is fitted on the upper portion of the vertical rustle 3 to suppress the combustion of dust around it. As a result, the upper unburned debris collapses inwardly toward the vertical loss trough 3 as the debris around the lower vertical rostles 3 progresses.

[0012] After the start of combustion, the hot air again rises from the vertical grate 3 into the combustion chamber 9 and the vertical grate 3 and the metal net layer 12 are heated in a short time to reach a considerably high temperature. As a result, the incompletely combusted gas that has escaped into the vertical rustle 3 is recombusted there, and the gas that has not been completely combusted there is recombusted in the recombustion chamber 9. By the way, since the re-combustion chamber 9 has a wider diameter than the vertical rostrur 3, the gas rising in the vertical rostrur 3 temporarily stays in the vertical rostrur 3 without entering at once and not rising upward. By fully contacting the metal mesh layer 12 that has become

[0013]

[Effect of device]

 Since the present invention is as described above, it can be provided at a price that is not much different from the conventional one with a simple structure, and since it has a vertically extending grate not only at the bottom but also at the center, dust from inside can be collected. Combustion is performed in good condition, and the incompletely combusted gas is re-combusted and re-combusted (complete combustion) in the vertical loss chamber and the re-combustion chamber to be discharged as pollution-free gas.
