DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a closed container for fermentation for treating garbage.

[0002]

2. Description of the Related Art As is well known, the disposal of garbage in Japan has relied on landfills for a long time. However, in recent years, the shortage of landfills has led to the reduction of garbage discharged from households as much as possible. Has been advocated.

One of such proposals is composting of garbage discharged from homes, and various proposals have been made (for example, Japanese Patent Publication No. 4-23600, Japanese Patent Application Laid-Open No. 62-65592, JP-A-61-141691
Gazette, JP-A-60-232301,
42934).

For example, in Japanese Patent Publication No. 4-23600 mentioned above, garbage discharged daily from home is put into a closed container, fermentation bacteria are added to the garbage, and the garbage is fermented on a short date and time to make the compost fully ripe. It is proposed to.

That is, in a closed container for fermentation for treating garbage, a filtering member, a fermentation promoting layer, and a garbage container are sequentially provided from the bottom in a container body provided with a drain port at the bottom and a closed lid at the top. The fermentation hermetic container is formed in such a manner that a storage room for the powdery fermentation promoter is provided in the closed lid, and a heat retaining jacket is provided in the container body.

In the proposed closed container for fermentation for treating garbage, the mouth of a synthetic resin filter bag is preliminarily opened in the container body, and garbage is sequentially charged into the bag. , Sprinkle powdered fermentation accelerator,
Keep at ~ 30 ° C. As a result, since 85% to 95% of the water contained in the garbage is taken out from the drain, the remaining shrunk garbage is fermented and decomposed into a mature compost. So you just have to take out this ripe compost with the bag,
It has been.

[0007]

However, unlike the bell-shaped compost container using the decomposition treatment method using aerobic microorganisms, such a fermented closed container for fermentation for treating garbage is used year-round even in snowfall areas. Although possible, there were the following problems.

Since the garbage is made into a fully matured compost, the garbage discharged daily is accommodated sequentially during the ripening period, so that the capacity of the container body is increased (for example, the bottom area is 16 m ² ). Since the temperature of the thermal insulation jacket is constantly controlled, it cannot be left unattended and is troublesome. The finished ripe compost is not always welcomed by farmers and eventually becomes self-supplied fertilizer.

Accordingly, the present invention has developed and implemented an extremely small, compact, and extremely easy-to-handle fermentation hermetic container which solves the problem of the proposed fermentable hermetic container for treating garbage. A problem has arisen between the closed vessel and the fermentation gas pressure, whose function is inconsistent with the above.

[0010]

SUMMARY OF THE INVENTION Accordingly, the gist of the present invention is as follows. 1) Powdered raw fertilizer fermented and adjusted by anaerobic microorganisms is added to household waste garbage which is successively charged into a container. Sprinkle, seal the container, and
A container used in a garbage disposal method in which the garbage is fermented to be composted by leaving it for a week, and the container is left in a place where sunlight does not reach, and the container is made of a small plastic bucket.

BRIEF DESCRIPTION OF THE DRAWINGS The invention will be described in more detail with reference to an embodiment shown in the accompanying drawings. FIG. 1 is an overall sectional view of an embodiment of the present invention, and FIG. 2 is a detailed enlarged view of a portion A in FIG.

First, the outline of the garbage disposal method using the closed container of the present invention will be described.

The garbage disposal method implemented by the present invention uses garbage as an organic fertilizer (composting).
It uses fermentation-synthetic microorganisms, but the inoculum to be added to this garbage includes lactic acid bacteria groups and photosynthetic bacteria that effectively ferment under anaerobic conditions, actinomycetes and filamentous fungi with antibacterial activity,
In other words, in order to increase the amount of this inoculum by using an anaerobic microorganism, the inoculum is added to rice bran, oil cake and the like, fermented, and then dried to obtain a powdery fermented raw fertilizer. 10-20 g of this fermented raw fertilizer per 1 kg of garbage put in a container
Sprinkle, close the container, and leave it for about 2 weeks to complete the low-temperature fermentation while generating fermentation gas. The fermented garbage thus produced is buried in the soil,
After a week, the compost becomes almost completely composted, sowing and planting it.

That is, according to the garbage disposal method of the present invention, a powdery raw fertilizer fermented by an anaerobic microorganism is sprinkled on garbage placed in a container, and the container is closed and left for about 2 weeks. This is a garbage disposal method in which low-temperature fermentation of garbage is almost completed, and then buried in the soil and then composted (for example, Japanese Unexamined Patent Publication No. Hei 6-72788, Agricultural use of microorganisms and environmental conservation by Teruo Higa). (See pages 208 to 211).

FIGS. 1 and 2 show a sealable container used for treating such garbage. Reference numeral 1 denotes a container body made of a synthetic resin (made of hard polypropylene) and having a diameter of about 34 cm and a height of about 40 cm, which is formed in a bucket shape. Is provided with a soft polypropylene sealing lid 4, and a filtering disk (also referred to as a snowboard) 5 is removably placed immediately above the bottom 2. About 16 liters of space is provided between the filtering disk 5 and the sealing lid 4. A garbage container 6 is formed.

A cylindrical leg 7 is integrally formed on the bottom 2 of the container body 1 in order to easily receive moisture from the drain port 3, and is provided on a front surface of the leg 7 in a vertical direction. Recess 7 in the direction
The drain port 3 is provided at a. The drain port 3 is for taking out the moisture of the garbage in advance or extracting the fermentation liquid during the garbage fermentation in order to shrink the garbage and improve the fermentation efficiency. The drain port 3 is formed of a stopper cock, and a cock body 9 with a knob is inserted into a cylindrical valve box 8.
An outlet 10 is provided in the valve box 8, and the outlet 10 is opened and closed by turning the cock body 9. The outlet 9 is provided with a small cap 11 in order to prevent dripping and insects.

A folded flange 12 is integrally provided around the upper opening of the container main body 1, and a ring-shaped convex portion 13 is provided on the entire periphery of the upper surface of the folded flange 12 at a substantially central portion in the radial direction. Have been. The ring-shaped projection 13 is opened in a funnel shape with a slight inclination. The soft closed lid 4
Abuts on the upper surface of the folded flange 12 to cover it. The lower surface of the sealing lid 4 is fitted to the ring-shaped convex portion 13 and the upper surface of the flange 12 A groove-shaped concave portion 14 that is in contact with the shore contact portions 14A and 14B is formed on the entire circumference. The groove-shaped recess 14 is inclined and provided so as to be parallel to the funnel-shaped ring-shaped protrusion 13.

Then, as shown in FIG. 2 in which the close fitting state is enlarged, a slight thickness (for example, between the outer diameter surface of the ring-shaped convex portion 13 and the outer diameter surface of the groove-shaped concave portion 14). 1.5m
When the wrap white 15 is formed and fitted into the concave and convex, the wrap white 15 is elastically deformed and fills the gap between the outer diameter surfaces, thereby completely sealing the container body 1 and the sealing lid 4. On the other hand, a space 18 is formed between the inner diameter surface of the ring-shaped convex portion 13 and the inner diameter surface of the groove-shaped concave portion 14 so that the ring-shaped convex portion 13 slightly escapes inside when fitted.

Here, when the garbage is fermented in the above-mentioned closed container, gas is generated.
That is, the pore 17 is provided at the position of the space 18. Therefore, when fermentation gas is generated in a closed container,
First, the central portion of the soft sealing lid 4 slightly swells, but when the fermentation gas further rises, the wrap sill 15 is fixed, the inner contact portion 14A is lifted, and the inside of the container and the pores 1 are removed.
7 communicates with each other through the space 18, the gas is released, and the gas pressure in the container decreases. As a result, the sealing lid 4 immediately returns to its original state, and is lifted, so that the contact portion 14A immediately contacts the upper surface of the flange 12.

Therefore, even if gas is generated in the closed vessel, the press-covered closed lid 4 does not come off and the gas is released, so that the anaerobic state for 1 to 3 weeks is maintained and stable fermentation is performed. be able to. In addition, in the container main body 1,
A carrying hand 16 is provided for carrying.

Next, the operation of this embodiment will be described. Regarding the treatment of garbage in general households, at least two closed containers of the present embodiment and a powdered raw fertilizer are prepared. Therefore, raw garbage (vegetable waste, fish bones, etc.) 25 discharged daily into one closed container is sequentially charged, and each time,
The powdered raw fertilizer is sprinkled, and the hermetic lid 4 is pressed against the container body 1 to hermetically seal it. Even though this closed container is small, the garbage 25 shrinks because the fermentation liquor collected in the bottom 2 is taken out from the drain port 3, so that the size of the garbage 25 can be reduced to about 1 to 3 weeks. When the garbage 25 accumulates in the sealed container for about eight minutes, the sealed container is placed in a dark place where sunlight does not reach, for about 1 to 1 minute.
Leave for 3 weeks. Meanwhile, the garbage 25 is fermented while generating a gas having a lactic acid fermentation odor, and when the gas accumulates in the closed container, it is automatically released through the pores 17,
The sealing lid 4 does not come off and does not cause anaerobic conditions. Since the odor of the gas is not the rotten odor of methane gas or the like, even if the gas is released indoors, the odor does not become so bad. Then, during this standing period, garbage is put in using another closed container.

When the generation of this gas stops, that is,
After the fermentation standing period of 1 to 3 weeks has passed, the fermentation of the raw garbage is substantially completed. When the fermented garbage is buried in the soil, complete compost is obtained in 1 to 3 weeks. Therefore, seeding or the like can be performed.

In this embodiment, a ring-shaped convex portion is provided on the folded flange 12. However, the present invention is not limited to this, and the periphery of the opening of the bucket body itself is a ring-shaped convex portion, and the groove provided on the lid is provided. A part of the recess shore outside the concave portion may be elongated to form a tongue piece, and the tongue piece may close a pore provided in the container body 1. In this case, the tongue is pushed open by the fermentation gas pressure, and the gas is released.

[0024]

According to the present invention, the following effects can be expected. In order to put the sequentially discharged garbage into the closed container each time, it is necessary to configure the lid as a closed lid that is extremely easy to handle such as opening and closing operations. That's why the gas is released by the pores that open and close with a part of the lid that deforms due to the fermentation gas pressure, so that the closed lid does not come off and the anaerobic state is not affected even if the closed container is left Absent. Therefore, the fermentation of the garbage can be stabilized and it does not become putrefactive. The closed container is placed in a dark place for a period of 1 to 3 weeks after the garbage is thrown in. However, since there are pores that open and close, management of the closed container becomes unnecessary, that is, the container can be left, and therefore, it can be left under the floor. We do not choose the setting place. Since it is only a part of the pores and the resin deformation, the safety valve and check valve are not particularly required because it is made of plastic in particular, and the sealing structure of the sealing lid is simplified, making it easier to handle. , And can be constructed inexpensively.
