Description

Description: FIELD OF THE INVENTION The present invention relates to a waste treatment device that heats and incinerates waste generated at home.

2. Description of the Related Art A general waste treatment device incinerates waste with gas,
There were those that were compressed and crushed, those that were fermented, etc., but all of these were unsuitable for home use due to reasons such as noise, foul odor, and degree of weight loss.

Therefore, the present inventors have considered a waste treatment device that uses a heater. Hereinafter, this garbage disposal will be described with reference to FIG. In the figure, 1 is a furnace material 2 having a heat insulating property.
Is a frame body having an inner surface, and has a lid 4 for closing the opening for introducing dust. Further, a convex portion formed so as to enclose the heater 3 is provided at the bottom of the processing container 5. The dust 6 thrown into the processing container 5 from the lid 4 is dried and incinerated by heating the heater 3. At the time of combustion, the required air flows in through the air supply port 7 by the blower 14, and the exhaust gas generated by combustion is heated from the exhaust port 9 into the purifier 10 by the purification heater 12 and purified by the catalyst 8 and discharged. It was

Problems to be Solved by the Invention In such a conventional configuration, even if the air required for combustion is supplied into the frame body 1 by the blower 14, as shown in FIG. The space between the side surface of the frame 5 and the frame 1 was mixed and discharged with the exhaust gas in many cases, and the air could not be efficiently taken into the processing container 5. As a result, the supply of oxygen necessary for combustion is insufficient and the ignition performance deteriorates, so it takes time to process, and unburned gas is generated from the smoldered state, causing explosion, odor, and smoke There was a problem that

The present invention solves the above-mentioned problems, and suppresses the generation of unburned hydrocarbon gas and carbon monoxide gas as well as accelerating the processing by improving the combustion in the processing container,
The purpose is to provide a waste treatment device that is free of explosion, odor, and smoke.

Means for Solving the Problems In order to achieve the above-mentioned object, the present invention provides a frame body having a lid that is openably and closably provided in an opening for throwing in dust, and a heater projecting from an inner bottom portion of the frame body. And a processing container for dust injection having a convex portion on the bottom surface for covering the heater, an exhaust port communicating with the frame body, and an air supply port for introducing air, and a plurality of ventilation holes are provided at the bottom of the processing container. A mouth is provided, and the vent hole and the air supply port are connected by an air supply passage.

Action With this configuration, air flows from the air inlet through the air inlet to the inside of the processing vessel through the ventilation port at the bottom of the processing vessel, and is not completely mixed with exhaust gas or discharged as it is, and is completely burned. It is used as air and can be converted into clean exhaust gas by complete combustion, which can reduce the size of the purification unit and prevent explosion.

Embodiment An embodiment of the present invention will be described below with reference to FIGS. 1 and 2. The same parts as those of the conventional structure are designated by the same reference numerals, and the description thereof will be omitted.

In the figure, a frame 1 having a lid 4 and having a furnace material 2 on the inner surface thereof
The processing container 5 having the heater 3 protruding from the inner bottom portion thereof and the convex portion 16 for enclosing the heater 3 formed on the bottom surface is disposed in the frame body 1. A wire mesh 15 having air permeability is provided on a side surface of the convex portion 16 of the processing container 5. Inside the convex portion 16, the heater 3
Is located, and the other end of the air supply passage 11 to which one end is connected is inserted. The air supply port 7 is connected to the blower 14.

In the above configuration, the dust 6 is put into the processing container 5 with the lid 4 opened, the lid 4 is closed, and when the heater 3 is energized, the dust 6 is heated through the processing container 5 and dried. When the drying is completed, the temperature rises above the boiling point, reaches the ignition point, and ignites. At this time, the air required for combustion is blown by the blower 14 through the air supply passage 11 into the convex portion 16 at the inner bottom portion of the processing container 5. As shown in FIG. 2, the blown air is heated by the nearby heater 3 and flows into the processing container 5 through the wire mesh 15 on the side surface of the protrusion 16 and is then heated without being mixed with the exhaust gas. Is supplied to the normally dried refuse 6. That is, since the heated hot air is directly applied to the dust in the processing container 5, the combustion state in the processing container 5 can be improved. When combustion starts, exhaust gas is generated, but the exhaust gas enters the purifier 10 through the exhaust port 9, is heated by the preheated heater 12 for heating exhaust gas, and is then purified and discharged by the catalyst 8. .

In this embodiment, the convex portion is provided with the wire mesh, but as shown in FIG. 3, a plurality of vent holes may be provided in the side wall of the convex portion 16, and as shown in FIG. As described above, a plurality of vent holes 18 may be provided on the entire bottom surface of the processing container 5, and the vent holes 18 and the air supply passage 11 may be connected.

EFFECTS OF THE INVENTION As is apparent from the above examples, according to the present invention, by supplying air from the bottom of the processing container to the inside of the processing container, the supplied air is opposed to the heat rise of the exhaust gas, or the exhaust gas is left as it is. Combustion can be improved by effectively mixing the exhausted air into the container and discharging it as it is. Further, it is possible to provide a waste treatment device that suppresses inflammable gas that is not present and that has little odor or smoke and does not explode.
