Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a domestic incinerator capable of incinerating garbage generated in general households, particularly kitchen garbage and wet garbage such as food packaging materials.

[0002]

2. Description of the Related Art Conventionally, in order to incinerate garbage generated in general households, water has been drained and naturally dried. There are many problems such as the generation of odors and insects due to putrefaction during drying, and most of the garbage is incinerated or buried by the administrative recovery system, and the disposal cost is enormous. Forced combustion with a burner etc. is possible, but the installation place is limited in general households and there is a problem in terms of fire prevention.

In general households, dry combustible dust such as paper dust and wood dust is also generated. Proposals have been made to use the heat of combustion of combustible waste to help dry wet waste. Of course, if you simply mix the two and incinerate them, the wet trash will wet the dry trash, and the burning heat of the dry trash will be directly absorbed by the nearby wet trash, extinguishing the fire as a whole. I will end up.

For example, in Japanese Utility Model Application Laid-Open No. 59-29528, the upper and lower chambers are constructed so that the heat of burning dry combustible dust in the lower chamber dries the raw dust in the upper chamber and rotates the room partition. To move the dried raw garbage to the lower combustion chamber,
A device to incinerate is proposed. However, since the two chambers are vertically stacked, the water droplets from the raw garbage on the top wet the dry combustible waste on the bottom, making it difficult to incinerate, and if the partition plate is made of a non-breathable plate to prevent it from getting wet, There is a problem that heat transfer from the lower chamber becomes weak and the garbage is not sufficiently dried.

Further, Japanese Utility Model Laid-Open No. 1-61524 proposes that a shelf for placing raw garbage is provided in the furnace, and the raw garbage is dried and incinerated by the heat generated by the combustion of the dry combustible dust in the lower part.
However, here again, the problem that the dripping water from the raw garbage wets the dry combustible waste below, and that this internal structure cannot put the waste into the upper part of the furnace, and it becomes a large-scale furnace, etc. There is.

[0006] In Japanese Utility Model Laid-Open No. 4-115227, two chambers are horizontally formed by partitioning in the vertical direction to form a garbage drying chamber and a combustion chamber. Although it is possible to prevent the dry dust from getting wet with the dripping water from the raw dust, the combustion heat of the dry dust is transferred through the partition wall between the two chambers, and the drying efficiency of the raw dust is very poor. Further, there is a problem in workability such that it is necessary to visually check the dry state of the garbage and move it to the combustion chamber.

[Problems to be Solved by the Invention] [0007] The present invention aims to provide a home-use incinerator that addresses the above-mentioned situation and is small and simple, capable of incinerating wet dust. is there.

[Means for Solving the Problems] The present invention is
The following measures are taken to achieve the above object.
That is, the incinerator is partitioned by the substantially vertical partition plate 5 to have a two-chamber structure, and the grate 11 of the chamber A for burning the dry combustible dust is used.
A ventilation port 10 is provided through the partition plate 5 at a position higher than the grate 12 of the chamber B that burns wet dust, and an openable dust inlet is provided at each of the upper portions of the two chambers. It is also used as a smoke outlet provided, and further, a removable bottom tray 8 is provided, and further, at least one of the grates 11 and 12 of the two chambers has a rotatable structure of 60 ° or more. ,.

The above invention will be described in detail below with reference to the drawings. FIG. 1 shows an example of the present invention. It is an incinerator divided into two chambers by a partition plate 5 positioned almost vertically,
Chamber A is a space for burning dry and combustible dust such as paper dust and wood dust. Room B is kitchen garbage such as raw garbage and food packaging materials,
This is a space for burning garbage that cannot be burned by itself, such as pruning debris from garden trees that gets wet or damp.

In the lower part of the chamber A, an intake port 9 is provided on the front side surface 1, and a rotating grate 11 is located above it. The rotating grate 12 is provided above the grate 11 also in the chamber B. A ventilation port 10 that penetrates the partition plate 5 is provided at a height between both grate. At the time of incineration, the lid 6 of the chamber A is closed and the lid 7 of the chamber B is open.

The dry combustible dust introduced into the chamber A is sucked into the intake port 9
The flame that is ignited and burned from
Wet trash such as raw trash filled in is dried and burned, and smoke is exhausted from the trash input port in the upper part of the chamber B.

The dripping water from the wet dust thrown into the chamber B does not fall onto the bottom tray 8 and does not wet the dry combustible dust in the chamber A, and the burning of the dry dust is completely affected by the wet dust. Absent. Since the flame from the chamber A directly heats the wet dust, it is quickly dried and burned. It is not necessary to move the wet dust to the incinerator after waiting for it to dry, as seen in the conventional example.

It is desirable to attach a grid or a crosspiece to the vent hole 10 so that the combustible dust in the chamber A does not drop into the chamber B.

As in this example, it is desirable to provide an openable / closable lid 7 on the upper part of the chamber B to serve both as a dust inlet and a smoke outlet, but a chimney may be used. The lid 6 of the chamber A is opened at the time of throwing in combustible dust and at the initial stage of ignition, or at the time of adding additional combustible dust, but is normally closed at the time of incinerating wet dust.
Let the flame of the room flow into the room B. It is also possible to place a wire mesh near the smoke exhaust port to capture and re-burn the scattered substances that accompany the smoke emission. The handle 13 opens and closes each lid.

The bottom pan 8 is attached to the main body by a stopper 16 as a separate pan from the main body. As seen in many commercial products, an ash outlet may be provided on the lower side of the chamber A or B, but the ash scraping work pollutes the surroundings and the ash removal is insufficient and takes time. Since workability is poor, it is convenient to use a separate type as in this example.
After the completion of the incineration, it can be left to cool, the stopper 16 can be removed, the main body can be lifted to separate the tray 8, and the tray 8 can be carried as it is to the ash disposal site.

In the incinerator having this structure, the air permeability of the grate affects the incineration efficiency. To prevent clogging of the grate, it is desirable to take vibrational or rotary clogging prevention measures.
By rotating the grate horizontally from the grate surface at an angle of 60 ° or more, preferably 90 ° or more, it is possible to almost completely drop the clogging material on the grate to the bottom, eliminating clogging. I can. The handle 14 is attached to the end of the rotating shaft of the grate having the rotating shaft 17 penetrating the right side surface 2 and the left side surface 4, and is manually rotated from the outside of the main body. The angle of the grate surface is controlled by fixing the rotating position of the handle.

On the main body, a hanging handle 15 is attached to the right side surface 2 and the left side surface 4. This is convenient when removing the bottom tray 8 or moving the main body. The shape of the hanging hand does not matter.

In FIG. 1, the main body has a prismatic shape, but it may have a cylindrical shape or a conical shape with a wide lower portion. Vent 1 provided in the partition plate 5 such as a corrugated cardboard-like object thrown into the chamber A
Vents may be obstructed by covering 0. For this reason,
You can also make the partition plate uneven or curved to help the passage of the flame. It is valid.

The material of the furnace is not particularly limited as long as it is a commonly used heat-resistant material, but heat-resistant metal is desirable for weight reduction, and chromium-plated steel or stainless steel is particularly desirable material from the viewpoint of rust prevention. is there.

[0020]

Function: Dry combustible waste is put into the chamber A, and wet waste such as kitchen waste is put into the chamber B. With the lid 7 of the chamber B and the lid 6 of the chamber A open, the dry combustible dust is ignited from the intake port 9, and the lid 6 of the chamber A is closed after the fire becomes strong, so that only the upper portion of the chamber B emits smoke. To do so. If the timing of charging to the chamber B is set as early as possible by ignition, draining and natural drying will proceed to facilitate combustion. When it is necessary to add dry combustible dust to help the burning of wet dust, the lid 6 of the chamber A can be sequentially opened. During incineration, when a weakening of the fire due to clogging of the grate is observed, the grate 11 or 12 is vibrated or rotated to eliminate the clogged state. After the incineration is completed, the grate 11 and 12 are rotated to drop the incineration residue on the bottom tray 8, and the stopper 16 is removed to separate the tray and carry it to the ash disposal site for disposal. At this time, it is possible to separate and dispose of the incineration residue in both rooms, and for example, only the ash in the room A can be used as fertilizer for the vegetable garden.

EXAMPLE An example of a columnar incinerator similar to FIG. 1 will be described. Table 1 shows the main specifications of the incinerator. In each example, the grate and the vent crosspiece have a diameter of 3 mm to 10 mm.
mm SUS304 round bar is welded and used.
A SUS304 plate material having a thickness of 0.6 mm to 1.0 mm was used.

[Table 1]

The first embodiment is an example of a square type or a medium type, and FIG.
The structure is shown in. The depth of the dry combustible garbage incinerator chamber A is 15 cm, and the depth of the wet garbage incinerator chamber B is 20 c.
m. Room B has no chimney or ash outlet. Figure 2
It is a top view of the grate of the chamber A. A 12 cm × 30 cm rectangular rod having a diameter of 5 mm was welded. The rotating shaft 17 has a diameter of 10 mm. Approximately 1 kg of kitchen trash consisting of raw trash and food packaging material scraps such as trays was put into the chamber B, and about 1 kg of dry combustible trash consisting of paper scraps and cardboard scraps was put into the chamber A and incinerated. Approximately 10 seconds after ignition of the chamber A, the charging port lid of the chamber A was closed and the flame started to be passed into the chamber B. About 1 minute later, room B
A red flame came to be seen from the upper charging port, and the burning of kitchen waste in the room B was observed. After that, good combustion continued, and the incineration was completed after about 13 minutes. Therefore, when the incineration residue in both chambers was observed, there was almost no residue, and it appeared as ash that had fallen to the bottom tray. The grate in both chambers was rotated, the remaining residue was received by a tray, separated from the main body, and landfilled. It was possible to incinerate raw garbage only with the garbage generated in general households without using a blower or a burner, and the workability during incineration and cleaning up was good.

The second embodiment is an example of a square type and a large type. Since the weight became heavier, the bottom tray was fixed to the main body, and the ash extraction port was provided on the rear side surface 4 of the chamber B. Further, a chimney for promoting combustion is attached to the upper part of the rear side surface 4 of the chamber B. About 1.5 kg of kitchen trash and about 2 kg of dry and combustible trash were thrown in and incinerated. The charging port lid 7 and the ash removal port lid of the chamber B are closed. About 7 minutes after ignition, weakening of combustion was observed, so the grate 11 in the chamber A was rotated to remove the residue, and then about 1 kg of new dry dust was additionally charged. It ignites without reigniting, and the combustion state in chamber B gains momentum again and becomes about 1
The incineration was completed after 0 minutes. After allowing to cool, both grate were rotated to remove the incineration residue, and the residue was scraped from the intake port 9 of the chamber A and the ash extraction port of the chamber B to dispose of it.

The third embodiment is an example of a round type and a small type. Although the outer shape of the main body is cylindrical, the basic structure is similar to that of FIG. The partition plate passes through the central axis of the main unit and
It is divided into equal parts. The grate of this example will be described with reference to FIG. The shape is a circle with a diameter of 29 cm and a height of 11.5 cm. When the grate is attached horizontally so that the distance from the inner wall of the body is 3 cm, and the rotary shaft 17 welded at the height of the missing circle of 3 cm is rotated as a center, the grate can be rotated up to about 120 °. Even in this example, the incineration of kitchen waste was good. Since it is lightweight, it is easy to move the incinerator, and it can be used as a garbage container near the kitchen, and when it is full, it can be moved to the incinerator and incinerated.

[0026]

As described above, according to the incinerator of the present invention, wet or damp dust such as kitchen dust and pruning waste of garden trees generated in general households can be treated with a burner, a blower or the like. There is an effect that it can be simply and cleanly incinerated by utilizing the incineration heat of general household waste such as paper waste and wood waste without any equipment.
