INVENTION The present invention relates to relates to household garbage anaerobic treatment vessel capable of processing liquid fertilizer in a substantially odorless garbage of the waste, such as farms, such as garbage and pigs of the home kitchen .

[0002]

2. Description of the Related Art In recent years, various researches have been conducted to treat household garbage and sewage from breeding grounds using microorganisms to reduce the amount of released garbage and to reduce BOD and COD in rivers and sewage treatment plants.
For example, as a method for treating household garbage, a method has been developed in which a combined treatment tank is used to perform anaerobic treatment, then aerobic treatment, and then flow it to a river or sewage treatment plant. However, there is a problem that an installation place is required to install the combined processing tank, and an exhaust device for methane gas or the like is required, so that it is difficult to install the tank for general households. Therefore, recently, liquid fertilization of kitchen garbage and the like using a microorganism group concentrate (trade names: EM-2, EM-3, EM-4, sold by Nippon Food Industry Co., Ltd.) has been developed and spread.

[0003] Conventional liquid fertilization of garbage and the like will be described below. FIG. 7 is a schematic view showing a longitudinal section when a conventional liquid manure extraction type garbage disposal container is used. 51 is a bucket-shaped container made of synthetic resin, 52 is a drainage hole formed in the lower part of the container 51, and 53 is a drainage drainage collected at the bottom of the container 51 fixed to the drainage hole 52. Pipe, 54 is container 51
A mesh body 55 made of a square material or the like appropriately arranged in the inside, a mesh 55 made of a wire mesh surrounded by wires arranged on the mesh body 54, and an inner lid 56 for covering garbage , 57 is the container 5
Reference numeral 58a and 58b denote locking means such as hooks for locking the container 51 and the pipe 53, and reference numeral 59 denotes a base portion formed of a block and the like disposed below the container 51. A method of using the conventional garbage disposal container configured as described above will be described below. Two containers 51 are prepared. One container 51 is placed on a platform 59 composed of blocks. Garbage such as kitchen garbage is put on the net 55 of the container 51. Then, the microbial community concentrate (EM-2,
A solution obtained by diluting EM-3, EM-4) 100- to 200-fold, respectively, is evenly applied to the surface of the garbage. Next, push the garbage with a stick or the like so that there is no gap between the garbage.
6 is put on top to make it anaerobic, and the garbage is decomposed and liquefied by microorganisms. This is repeated and accumulated each time garbage comes out. Whenever the drained water or liquid fertilizer accumulates at the bottom of the container 51, the pipe 53 is knocked down to extract the liquid fertilizer, and the liquid fertilizer is diluted 50 to 100 times and used as a planter or a field fertilizer. When one container 51 is full of garbage, the garbage is put into another container 51 and the same operation as described above is repeated. 4-5 full garbage disposal containers 51
The garbage is left as it is for a week and almost all of the garbage is decomposed and fermented. The residue is buried in a field or the like, and then the container 51 is washed to remove the clogging of the net 55 to prepare a next garbage disposal container.

[0004]

However, in the above-described conventional configuration, since it is a simple configuration, it can be easily installed by anyone, but there are the following problems for continuous use, and improvement has been strongly desired. When pushing the garbage with a stick, the wire mesh bends and undegraded garbage falls to the bottom of the container, causing a problem that the fermented liquid of the garbage is spoiled and produces a bad smell, and the wire mesh is oxidized by acid or the like. Therefore, there is a problem that the durability is extremely short and cannot be used. In addition, there was a problem that the net made of synthetic resin was easily bent and could not be used. Since the net receiver is unstable, it falls down due to vibration or the like, and garbage leaks from the net to the bottom of the container, causing rot and causing a bad smell. The problem is that the drainage pipe is easy to fall down, the fermentation liquid flows out and pollutes the environment, and the air enters into the container and becomes aerobic, rots the garbage, emits a bad smell, and the fermentation liquid is contaminated with various bacteria and cannot be used as liquid fertilizer. was there. Because of the large number of parts, there is a problem that cleaning is difficult and dirty. There has been a problem that the accident that containers are dropped from the block table and the garbage is scattered when the garbage is thrown in or when an object hits the garbage is inevitable. Since all the garbage is collected on the wire net, there is a problem that it is difficult to drain the garbage and the garbage is not fermented and easily rot.

The present invention solves the above-mentioned conventional problems, and provides a household garbage disposal container capable of efficiently producing excellent liquid fertilizer which is easy to handle, easy to clean, has excellent durability and excellent fermentation efficiency. The purpose is to:

[0006]

Means for Solving the Problems To achieve this object, the garbage anaerobic disposal container for household use of the present invention has the following constitution. The household garbage anaerobic treatment container according to claim 1, wherein the outer container has a bottom portion and a peripheral side wall with an opening on one side, and a drainage portion including at least one stopcock is formed at a lower portion of the side wall; A one-sided opening accommodated in the outer container, having a bottom and a peripheral side wall, a straining portion formed of a plurality of 1 to 30 mm drainage holes formed in the bottom and a lower part of the peripheral side wall formed in a lattice shape.
An inner container in which a strainer for a peripheral wall for draining is formed, and a leg is formed outside the bottom, a lid disposed at an opening of the outer container, and A sealing portion made of a rubber material or the like formed on the contact surface with the opening of the outer container,
A mesh body disposed on the lower surface of the strainer at the bottom of the inner container,
Is provided. The garbage disposal container for household garbage according to claim 2 is characterized in that, in claim 1, a see-through portion for checking a liquid level is formed at a lower portion of a peripheral wall portion of the outer container and / or a leg portion is formed outside a bottom portion of the outer container. It has the configuration that has been done.

Here, the outer container and the inner container may be made of metal or synthetic resin, but are preferably made of synthetic resin from the viewpoint of integral molding and mass production. Further, it is preferable that the outer leg portion at the bottom of the outer container be at least as high as a basin or a small jar can enter below the drainage portion, because it is convenient to extract the fermentation liquid. The strainer consisting of a drain hole drilled at the bottom of the inner container and below the peripheral side wall is preferably 1 to 30 mm.
Holes of 5 to 15 mm are appropriately formed in consideration of drainage efficiency. In addition, a metal or synthetic resin mesh body is disposed outside the bottom, and the engagement method is such that a synthetic resin-made press ring or a leg inner side is cut from the inner container leg side. It is preferable that the projections or hooks are formed so as to be detachably engaged with the projections or the hooks, because the cleaning operation can be performed extremely easily. Depending on the content of the garbage (such as kitchen garbage and garbage in the breeding ground), the inner lid for the inner container can effectively prevent the generation of flies, etc., when the outer container is made large and multiple inner containers are placed inside, or depending on the contents of the garbage (garbage and garbage at the breeding ground). preferable. In particular, when the garbage is garbage garbage and contains cow dung, it is preferable to dispose the net in the strainer. It is possible to prevent the feces from being finely dispersed and falling into the fermentation liquid and causing the fermentation liquid to spoil. One or more transparent portions are used to confirm water or fermentation liquid level accumulated at the bottom of the outer container by making the wall thickness thin or the like. The seal portion of the lid portion only needs to be one that can prevent invasion of outside air to some extent and can exhaust CO ₂ gas and the like generated during fermentation of garbage.

[0008]

With this configuration, the stiffness of the strainer at the bottom of the inner container is extremely high, so that the garbage can be pushed in very easily and the inside of the garbage can be put in an anaerobic state. It can be fermented and decomposed to obtain excellent liquid fertilizer. Since the fermentation efficiency is high, garbage can be treated hygienically without producing putrefaction odor and the like. The stopcock can keep the inside of the outer container hermetically closed, and at the same time, can drain water when putting garbage and drain fermented liquid (liquid fertilizer) at any time. The garbage can be prevented from being infiltrated by the drained water or the fermentation liquid by the legs of the inner container. The liquid level of the drained water and the fermentation liquid can be confirmed by the see-through portion, so that the infiltration of garbage can be prevented. Since the outer container has legs, the fermentation solution can be transferred to the jar without the need for a separate block or the like. The anaerobic state can be maintained by the sealing portion of the lid.

When the garbage is formed, the odor can be prevented even if the garbage rots, so that the inner lid 12 need not be used.

[0010] For household garbage anaerobic treatment vessel of the embodiment constructed as described above will be explained how to use. First, the stopcock 6 of the outer container 1 accommodating the inner container 7 is closed, the lid portion 5 is taken out, and kitchen garbage and garbage from the breeding place are put into the inner container 7. The water in the garbage is removed by the strainer 7 on the side wall and bottom.
a, 9a. Egg shells are crushed and garbage is pushed in with sticks for deaeration. Bottom strainer 9
Is integrally formed with the inner container 7 and the hole 9a for liquid strainer is formed relatively large, so that it can be easily pushed in with a stick or the like and can be sufficiently drained. The fine garbage that has passed through the hole 9a for liquid straining is captured by the net 10, so that it is prevented from falling to the bottom. Furthermore, since the inner wall 7 is provided with the peripheral wall strainer 7a, the drainage can be quickly performed, and the garbage can be made anaerobic in a simple and short time. The level of the drained water can be confirmed by the see-through portion 4, so that the stopcock 6 can be opened and drained to an appropriate level. Next, a microbial concentrate for decomposition and fermentation or the like is sprinkled over the garbage, the inner lid 12 is covered, and the lid 5 is covered. This is repeated until the inner container 7 is almost full, and the fermented liquor that has flowed down is appropriately opened by opening a stopcock and diluted 100 to 500 times to obtain liquid fertilizer, which is applied to plants such as planters and fields. When the inner container 7 is full, leave it for about a week to ferment the garbage that was last added, then drain the fermentation liquor as liquid fertilizer, and bury the residue in the inner container 7 in a field or in a garbage bag. Put it in and throw it away. When the last garbage is fermented, garbage is put into another garbage disposal container and the fermentation is performed in the same manner as in the related art.

As described above, according to the present embodiment, the strainer is formed integrally with the inner container with the legs, and is doubled. So that the garbage does not fall into the fermentation liquor,
It is possible to produce an odorless and hygienically excellent fermentation liquid without causing spoilage. The see-through part checks the condition of the draining water and the accumulation of the fermentation liquor, and can be removed at any time with a stopcock, so that garbage can be fermented and decomposed with high efficiency without immersing the garbage in the fermentation liquor. Garbage can be processed in a short time of 1/2 to 1/3. Furthermore, since the outer container and the inner container are configured differently, each can be separately washed.
Also, since the net of the straining part is also detachable, the net can be removed and the straining part can be easily washed, thereby greatly improving the cleaning workability. The number of the see-through portions may be increased or may not be provided depending on the size of the garbage disposal container or the thickness of the peripheral side wall. In addition, the outer container is formed in a size that can accommodate two or more inner containers, and a stopcock is formed at the lower part of the front wall of each inner container storage part. If the garbage is stored in the next inner container, the garbage can be efficiently fermented and decomposed without taking up space.
