BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a food waste extinguishing stirring apparatus for decomposing food waste with microorganisms, and more specifically, mixing and agitating food waste and microorganisms while supplying water and air to the food waste. The invention relates to a stirrer for eliminating food waste that decomposes into carbon dioxide gas.

[0002]

2. Description of the Related Art Food waste is inevitably discharged in daily life and production activities of human beings. BACKGROUND ART Conventionally, the amount of food waste generated from households and other food and drink businesses has been incinerated or landfilled in landfills and disposed of at treatment facilities provided in urban areas. However, recently, the amount of food waste has sharply increased with the improvement of living standards and economic growth, and in the case of incineration and landfill disposal, the increase in fuel costs and labor costs for incineration and the disappearance of landfill disposal sites alone. It is difficult to process it. For this reason, a food waste extinguishing stirring device has been developed that can be disposed of by being decomposed into water and carbon dioxide using microorganisms for disposal by ordinary households and other food and drink businesses.

For example, Japanese Patent Application Laid-Open No. 8-108166 discloses a skeleton frame, a microbial activation treatment tank in which a kneading barrel having a substantially U-shape is formed, and a heating device capable of adjusting the temperature. A food waste disposer has been proposed in which a horizontal shaft type rotary shaft with an arm rod having a stirring blade is horizontally installed at the center of the inside of the chemical treatment tank. In this food waste disposer, an arc-shaped breathable member is further stretched on the bottom of the kneading barrel to supply air for microorganisms and discharge generated water.
As a result, it is possible to provide an economical food waste disposer that has a simplified structure and is compact as the entire device. In addition, for example, in Japanese Patent Laid-Open No. 9-254563, a tubular garbage fermenter is arranged in a vertical direction, and a stirrer is provided in the fermenter to stir and mix raw garbage, etc. There has been proposed a food waste processing apparatus having a stirring means in which a stirring blade that pushes upward and a stirring blade that pushes downward are attached to one vertical stirring shaft. As a result, it is possible to provide a food waste processing device that uniformly mixes food waste and compost and continuously ferments. Furthermore, for example, in Japanese Patent Laid-Open No. 10-118620, a fermentation tank, a control unit including a control substrate, an upper lid to which a sealing material is adhered, and the like are provided, and a garbage throwing opening for throwing garbage into the fermentation tank, This is a garbage disposal device provided in a processing tank and equipped with a carrier and a stirring blade for stirring food waste. As a result, the kitchen waste is mixed and processed by the stirring blade and discharged from the residue extraction port at the bottom of the fermentation tank.

[0004]

However, the above-mentioned food waste processing apparatus and the like have the following problems. When a horizontal screw type stirring blade such as the one disclosed in Japanese Patent Laid-Open No. 8-108166 is used, the efficiency of stirring the garbage in the microorganism activation treatment tank is not necessarily high. When agitated by rotating the horizontal axis, the food waste in the microbial activation treatment tank is sent in the direction opposite to the stirring direction of the stirring blade and pressed against the wall surface in the treatment tank, so that along the inner wall surface in this treatment tank. Therefore, there is a problem that the food waste locally stays and the stirring efficiency of the food waste becomes low. Further, in a vertical processing tank such as the above-mentioned food waste treatment apparatus proposed in Japanese Patent Laid-Open No. 9-255463, the food waste is compacted in the lower part, and it is difficult to uniformly mix the food waste with the microorganisms. Garbage that stagnates without mixing may occur. Furthermore, there are problems that the air and water are not sufficiently supplied to the microorganisms, the active environment of the microorganisms is impaired, and odor is generated because the garbage cannot be decomposed. Further, in a semicircular fermentation tank or processing tank such as the food waste disposer disclosed in JP-A-10-118620, a large load is applied to the stirring blade when a large kitchen waste is thrown in, so the stirring motor is energized. It may stop. In this case, there is a problem that it is necessary to separately remove the kitchen waste caught on the stirring blade.

The present invention has been made in view of the above problems, and an object thereof is to improve the mixing property of the microorganisms in the microorganism activation treatment tank and the garbage by stirring and to increase the temperature of the microorganism activation treatment tank. Another object of the present invention is to provide a food waste extinguishing agitator capable of maintaining a constant humidity environment and efficiently performing decomposition processing in a short time without generating odor. In addition, it facilitates air supply and water replenishment / drainage to prevent the reduction of microorganisms, enhances the activity, and reduces the number of times of microorganism replenishment.
An object of the present invention is to provide a food waste extinction stirring device having high extinction processing capacity. Further, it is another object of the present invention to provide a food waste extinction stirring device having a microbial activation treatment tank which can be smoothly rotated even if a large amount of food waste is thrown in, without imposing a heavy load on the stirring blade.

FIG. The regular polygon includes a regular triangle, a regular quadrangle, a regular hexagon, and the like. In particular, a regular hexagon or more is preferable in order to effectively use the volume. On the other hand, when a large amount of garbage is thrown in, the larger the difference between the diameter of the inscribed circle and the diameter of the circumscribed circle of the regular polygon, the larger the gap between the stirring blade 13 and the microbial activation treatment tank 12. Moreover, the rotation of the microorganism activation treatment tank 12 can be made smooth. Particularly, the regular polygon is preferably a regular dodecagon or less. Therefore, the regular polygonal microbial activation treatment tank 12 is preferably a regular hexagon or a regular dodecagon, and more preferably a regular hexagon. This is because the regular hexagonal honeycomb structure makes it possible to disperse the weight of food waste inside and the force such as impact from the outside, which makes the structure stronger.
