Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a garbage disposal device. More specifically, the present invention relates to a food waste processing apparatus that can easily and easily dispose of food waste on the spot, and can reduce the burden on the surrounding environment.

[0002]

2. Description of the Related Art Conventionally, raw garbage discharged from homes, for example, has been separately collected, incinerated, and then discarded. However, in recent years, this waste treatment has developed into a social problem and the protection of the global environment has been demanded, and it is difficult to deal with such conventional waste treatment alone.

[0003] Therefore, there has been a growing search for raw garbage treatment in consideration of environmental protection, and an attempt has been proposed to treat raw garbage in a place where raw garbage is generated such as at home. For example, as an example thereof, a garbage disposal as schematically shown in FIG. 3 has been developed so far. This garbage processing machine has a charging port (A) for charging the garbage at the top, and this charging port (A) is provided with a lid body (A) that can be opened and closed by rotating upward. There is. Inside, there is a processing tank (c) that decomposes raw garbage.
By lifting the lid (a) upward and opening the charging port (a), raw garbage to be processed can be charged into the processing tank (c). The processing tank (c) is filled with, for example, wood chips in which microorganisms are parasitic as a garbage processing material.

[0004] In such a garbage disposal, in the processing tank (c), the pre-filled garbage disposal material and the garbage (d) introduced through the inlet (a) are mixed. , Microorganisms in raw garbage processing materials decompose raw garbage (D) to the extent that it does not affect the environment (fermentation)
To do. Therefore, inside the treatment tank (c), a stirring blade (e) that thoroughly mixes and mixes the garbage processing material and the garbage (d) rotates the rotating shaft (f) arranged horizontally. It is also rotatably arranged as the center of.

Further, as schematically illustrated in FIG. 4, it has also been possible to install a garbage crusher (ki) called a disposer for crushing raw garbage (d) in, for example, a sink part (h) of a sink. Has been proposed to. In this case, the garbage (d) generated by cooking or the like is put into the disposer (ki), and after finely crushing the garbage with the disposer (ki), the crushed garbage can be discharged together with water.

[0006]

However, most of the garbage disposal shown in FIG. 3, for example, is installed outdoors alone, and therefore the user is in the kitchen (ke). After draining the raw garbage (D) at a place where the raw garbage (D) is generated, the user himself / herself has to carry it to the raw garbage processing machine installed outdoors. As described above, the garbage disposal has a drawback in that the convenience is not substantially improved from the conventional garbage box.

On the other hand, the disposer (g) illustrated in FIG. 4 can be easily treated at the same time as the garbage (d) is generated in the sink part (h) of the sink and can be discharged outdoors. Have advantages. However, in the case of the disposer (ki), since the garbage (d) is crushed and discharged together with water, there is a problem that the wastewater contains high-concentration organic substances and a large amount of solids. If this is discharged as it is, the burden on the water environment, the sewage treatment facility, etc. will be increased, and this will have an adverse effect.

Therefore, in order to solve the problem of the treatment of organic matter and solids in the wastewater of the disposer, for example, as shown in FIG. 5, a solid-liquid separator (K) and a water treatment device (support) are used. ) Is considered to be combined with the disposer (ki). However, in this case, it cannot be put to practical use unless the problems of recovering solids from the solid-liquid separator (K) and treating sludge discharged from the water treatment device (K) are solved. .

In addition to the above, an apparatus for physically or mechanically treating food waste (D) based on the dehydration method, the combustion method, the drying method, etc. has been provided so far. The reality is that it is not sufficient in terms of cost, maintenance and convenience. The present invention has been made in view of the circumstances as described above, and eliminates the drawbacks of the conventional garbage treatment, and more easily and easily treats garbage at the place where households or the like generate it. It is an object of the present invention to provide a new food waste treatment device that can reduce the burden on the surrounding environment.
