[Prior art]

 In general, most of the raw garbage is not recycled and used effectively at each home, but most of it is left to the waste collection truck. Therefore, recently, the garbage disposal capacity has reached the limit in any local government, and this garbage disposal problem has been highlighted as one of the environmental problems.

On the other hand, conventionally, it has been attempted to incinerate garbage in each house by using a small incinerator without sending out the garbage for garbage collection. However, such an incineration method has a problem that not only there are restrictions in terms of equipment, cost and space, but also the environment is deteriorated due to air pollution. On the other hand, recently, there is also a device in which a disintegrator called a disposer, which disintegrates raw garbage and discharges it rawly into sewage, is installed in a kitchen set, but this is contrary to the idea of recycling garbage. There was a problem of doing.

Therefore, as a measure to overcome the above problem, it is required to develop a garbage disposal method that can meet the request for recycling without incineration or disposer. On the other hand, there is a need for a new technology that decomposes and reduces the amount of garbage by using aerobic bacteria, converts it into organic compost, and reuses it for planting trees and growing vegetable gardens.

A main object of the present invention is to provide a simple device that can easily convert raw garbage into organic compost at each home. A specific object of the present invention is to provide a garbage composting device which is reliably reduced in weight, does not emit a bad odor, and is easy to handle.

[Embodiment of device]

 With the above-structured raw garbage composting device of the present invention, the lid at the entrance is opened and the drained raw garbage is put into the storage basket, and then an anti-eclosion agent (such as flies that prevents pupae from becoming adults) Then, add mulch and sawdust to promote microbial activity and close the entrance lid. If there is an appropriate humidity and air supply there, aerobic bacteria in the mulch will decompose the garbage. This makes it possible to easily reduce the volume of raw garbage, which was previously mostly collected in each household for garbage collection, by composting raw garbage, and the organic compost thus obtained can also be used directly for horticulture. Therefore, it can be safely and effectively used as leaf soil for composting.

An embodiment of the present invention will be described below, but the present invention is not limited to this embodiment. FIG. 1 is a schematic cross-sectional view showing an embodiment of the garbage composting device according to the present invention. The garbage composting device of the present invention shown in this figure is composed of a container body made of foamed resin, which comprises a storage part 1 and a lid part 2, and a storage basket 3 which is detachably stored in the main body storage part. ing.

Here, the container body is preferably a box-shaped container made of a material having heat insulating and heat retaining properties, and more preferably, it is made of a foamed resin such as styrene foam or polyethylene foam that can be easily obtained and easily manufactured. To be done. By using this type of adiabatic and heat-retaining container, it is possible to prevent the heat of fermentation from being dissipated in the composting device for raw garbage during the low temperature period, and to maintain the raw heat decay environment that is the same as during the warm period. it can. That is, if the container body is configured in this way, it is possible to maintain a temperature environment suitable for the growth and activity of microorganisms, regardless of the outside air temperature.

In such a container body, the storage section 1 has a plurality of ridges 4 on its inner wall and inner bottom surface. In addition, a plurality of air holes 5 are provided in the upper part of the storage part 1, and a drain hole 6 is provided in the lower end of the side wall. Further, the inner bottom surface of the storage part 1 is formed so as to be inclined downward toward the drain hole 6 for collecting water. On the other hand, the lid portion 2 has a structure in which a medium-height inclined surface is formed on the inner wall surface of the lid portion 2, and water droplets flow down toward the inner side wall of the storage portion 1 along the inclined surface.

The storage basket 3 is formed with a large number of holes for draining and venting, the top of which is open. As such a basket, for example, a resin-coated wire mesh or a stainless steel wire mesh is used as a material, a resin net or a rough fiber cloth is attached to a frame, or a porous body is used as a material. It can be used as long as it can drain water and aerate.

In the device configuration as described above, the air holes 5 are holes for sucking and exhausting oxygen (air) which is indispensable for the survival of microorganisms. Oxygen inhaled from the air holes 5 passes through a large number of aeration holes formed in the storage basket 3 and is supplied into the mixture of garbage and aerobic bacteria to promote the action of microorganisms. As a result, the garbage is decomposed and fermented by the action of the microorganisms and converted into organic compost. In particular, if oxygen does not reach the inside of the garbage stored in the storage basket 3, it may cause spoilage. In this case, it is desirable to mount a plurality of porous cylinders 7 in the storage basket 3 as shown in FIG. 2, which can assist the oxygen supply to the inside of the garbage and prepare the microbial environment. .

Proper humidity is also required for the reproduction and activity of such microorganisms. However, when the decomposition and fermentation of raw garbage by these microbes progresses, heat is generated, and the heat evaporates the water in the raw garbage, forming water droplets on the inner wall surface of the top lid and dropping it again onto the raw garbage. In this case, there is a problem that the water content in the garbage increases, which hinders the survival of microorganisms. In this respect, according to the present invention, as shown in FIG. 1, the lid portion 2 has an inner wall surface formed with an inclined surface having a height of 16 °, preferably an inclination angle of 16 °. It is configured so as to flow down toward the inner side wall of the storage unit 1 along. Then, the water droplets are discharged to the outside of the apparatus through the water draining hole 6 provided at the lower end of the side wall of the storage unit 1 together with the water directly discharged from the garbage.

Thus, the supply of oxygen and the maintenance of appropriate humidity are important for the reproduction and activity of microorganisms. Therefore, in this invention, in order to supply oxygen and maintain an appropriate humidity, as shown in FIG. 1, the storage part 1 of the container body is provided with a plurality of protrusions 4 on its inner wall and inner bottom surface. Moreover, the inner bottom surface is inclined downward toward the drainage hole 6.

That is, the ridges 4 prevent the storage basket 3 from contacting the inner side wall and the inner bottom surface of the main body, and when the air (oxygen) taken in from the air holes 5 is supplied to every corner of the storage basket 3. Together, they play a role of forming a passage for guiding the water droplets flowing down along the inner wall surface of the lid portion 2 or the water directly discharged from the garbage to the drainage hole 6. It is desirable that such ridges 4 be provided in the vertical direction where the flow of water and the air (oxygen) are well ventilated or toward the drainage holes 6, and the number of ridges 4 should be stable support of the storage basket 3 and seats. From the standpoint of preventing bending, it is desirable to provide at least one on each wall surface.

The air holes 5 and the water draining holes 6 described above are used to prevent insects such as flies from entering from the outside and prevent the generation of lines and the like, as shown in FIG. Should be provided.

When raw garbage is treated using the raw garbage composting device having such a configuration, the capacity thereof decreases and aerobic bacteria continue to grow. Therefore, raw garbage is stored in the storage basket 3. It is possible to add more wastes one after another and react repeatedly until the storage basket 3 becomes full, and the volume reduction of raw garbage can be easily realized by composting the raw garbage.

The present invention is not limited to the above embodiment, and the material and shape of each part are arbitrary except the material and shape specified in the present invention.
