DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for odorless decomposition of garbage for eliminating garbage such as cooking waste discharged from general households and the food and beverage industry and processed waste discharged from the food and feed industries. It is about.

[0002]

2. Description of the Related Art Conventionally, in Japan, garbage generated at home is processed by local governments, and food waste generated in the food industry is processed as industrial waste by a specialized trader. At that time, garbage is treated by landfilling and incineration. In the past, pig farmers had collected them as feed, but now most do not do so because they have switched to compound feed.

In addition, due to the limitations of municipal garbage disposal capacity, municipal governments have been conducting self-treatment of garbage at homes for as long as possible for about 10 years. In other words, a plastic container with a bottomless lid is placed on the soil, garbage is put into the container, and the decomposition is performed by a natural method. Furthermore, recently, "garbage disposal equipment" which can decompose garbage by soil bacteria having an organic matter decomposing action and use the processed material with various fertilizers
Has been developed by various manufacturers.

[0004]

However, the conventional garbage processing method has the following problems. (A) Landfill processing includes landfill reclamation, landfill in mountainous valleys, and underground burial. Any of these methods will lead to the destruction of natural phenomena. In addition, the occurrence of pests and odor pollution on local residents is inevitably involved. Therefore, such a treatment method is not desirable in these days when the problem of environmental protection is attracting attention internationally. Furthermore, the biggest problem with the landfill method is that there is naturally a limit in the small and limited land area as in Japan.

[0005] (b) Incineration treatment involves high equipment costs and is not economical, and there are numerous problems such as generation of carbon dioxide gas and scattering of harmful substances in the incineration process.

(C) In-house treatment of garbage in each household has the following disadvantages. Requires soil. The odor increases daily. Accompanied by the occurrence of maggots and flies. Although it is naturally decomposed, its volume is only slightly reduced, and the input garbage increases and overflows every day. Inexpensive containers are easily damaged. The plastic container is completely lacking in weather resistance due to the composition at the time of production. Dogs and cats cause garbage scattering pollution.

(D) Conventional garbage processing apparatuses developed by various manufacturers have the following disadvantages. In a processing apparatus that promotes the growth of anaerobic microorganisms, there is a great risk of odor generation. Some are equipped with a heater so that they can be used even in winter, but they are not so desirable from the viewpoint of energy saving and economics. In the case of a horizontal stirring mechanism, the size of the apparatus is increased. The conventional vertical stirring mechanism can save space compared to the horizontal stirring mechanism, but it has been difficult to uniformly stir the powder at the bottom and the powder at the upper layer. There are a large number of operation panels, the operation method is complicated, and the operation is difficult, and there is no one developed from an ergonomic point of view.

The present invention has been made in order to solve the above problems.
An object of the present invention is to provide a method for odorless decomposition of garbage, which can decompose garbage odorlessly, sanitarily, and efficiently.

[0009]

In order to achieve the above object, according to the present invention, a garbage decomposing medium for filling a processing tank body with a garbage decomposing medium in which aerobic bacteria have been implanted in tree flour. ZaiTakashi Hama process and a garbage-on step of turning to open the garbage put a lid provided on the dust inlet garbage in garbage turned portion, the press-fitting blades to start the closure of the garbage introduced lid, stirring The lower side of the garbage disposal tank for the garbage thrown in by the wings
A garbage press-in / diffusion process in which the body is pressed and diffused into the treatment tank body, and a certain amount of air is supplied into the treatment tank body,
An air supply step of supplying and permeating air to the entire area of the garbage decomposition medium, and in the air supply step, external air
From the gap between the garbage input lid and the garbage input port,
In the garbage disposal tank body with garbage odor in the garbage input section
The garbage is fed into the garbage disposal tank , and the garbage that has been injected and diffused into the garbage disposal tank body is rotated by the stirring blades . <br/> The garbage in the lower layer is mixed with the garbage decomposition medium. A garbage decomposition process in which the garbage is uniformly stirred by the rotation of the stirring blades around the central axis while moving to the upper tank, and a garbage decomposition tank is decomposed in the garbage processing tank body and adsorbed and accumulated in the garbage decomposition medium. And a discharge step of discharging the processed garbage to the outside of the machine.

[0010]

[Function] First, the garbage input palate is opened with the input palate hinge as a fulcrum, and garbage is input from the garbage input port. When the garbage input lid is closed, the automatic start / stop sensor provided in the garbage press-in unit operates, and the press-in wing drive and stirring blade drive automatically operate. After a few seconds have passed after the agitator drive has been activated, the orbital drive is activated.

The garbage put into the garbage press-in unit is
Due to the rotation of the press-fitting wings, they are evenly spread and press-fitted into the garbage treatment tank main body. And, in the garbage processing tank body,
The garbage at the bottom is moved to the upper layer together with the garbage decomposing medium by the rotation of the inner stirring blade and the outer stirring blade, and is uniformly and efficiently stirred and decomposed by the revolving motion around the central axis. .

On the other hand, since fresh oxygen must always be supplied to maintain the odorless decomposition for a long period of time, it is provided from the air supply device to the middle part of the heat insulating material on the back side of the garbage disposal tank main body. A certain amount of air is sent into the garbage disposal tank main body from the opening through the air supply pipe.

At the same time, by operating the intake door, the outside air penetrates the whole area of the garbage decomposing medium through the mesh of the meshed seat plate from the air inlet / emergency drain. Then, the air is discharged to the outside from the air outlet through the gas inlet opening and the gas decomposition agent case.

The outside air is also sucked from the groove in the gap between the garbage inlet and the garbage press-in unit, passes through the gap between the garbage dissolving medium, and reaches the opening of the top plate for intake. Is discharged. Therefore, the odor of the garbage attached to the input port is also drawn into the treatment tank main body, and the odor from the input port is completely eliminated. As described above, since the supply of oxygen is always forced into the garbage processing tank main body, the activity of microorganisms is activated, and the amount of garbage can be eliminated and eliminated several tens times faster than natural decomposition.

By using a garbage decomposition medium agent,
Decomposed water generated from garbage is absorbed by the garbage decomposition medium agent, and at the same time, is evaporated and eliminated by the ventilation of the garbage processing tank body by the air supply unit and the intake door, and there is no drainage. . In the unlikely event that a large amount of garbage with a high water content such as juice is thrown in by mistake and exceeds the water content of the garbage decomposing medium, the excess decomposed water will naturally pass through the gap between the garbage decomposing medium. It sinks and is discharged to the outside from the emergency drain through the mesh of the seat with mesh.

[0016] By the action of the garbage decomposing medium, garbage such as leftovers and vegetables is eliminated within one week,
Even hard bird bones, etc., disappear in about 10 days. After a considerable period of time (about 2 months) after the garbage is put, nitrogen, phosphoric acid, potassium, etc., such as the three major nutrients contained in the garbage, are adsorbed and accumulated in the garbage decomposition medium, and the fertilizer effect It becomes a soil improver with high.

The garbage decomposing medium 39 used in the process of filling the garbage decomposing medium is obtained by extracting and cultivating the organic matter decomposing microorganisms existing in the soil by applying the principle of elimination and elimination of buried soil. It has been implanted in tree flour instead of soil. Since the short-day decomposition by the method of underwater decomposition is mechanically costly, the same principle as that of soil burial in nature is adopted, and instead of soil, wood flour is used. The harmful substances are detoxified and sterilized by heating at 130 ° C to improve the implantation and growth temperature of the decomposing bacteria. At the same time, the germination inhibiting ligninsan is decomposed to be ineffective, so that it can be used as an organic fertilizer. Has increased safety.

Further, the configuration may be such that all the driving mechanisms are stopped simultaneously with the opening of the garbage input lid 13.

[0038]

According to the present invention, the following excellent effects can be obtained.

(1) Since fresh oxygen is forcibly supplied into the main body at all times, odorless decomposition can be continued for a long time, anaerobic microorganisms cannot survive, and aerobic microorganisms can survive. Oxidation and odorless decomposition of garbage can be completely performed.

(2) Since the spiral stirring blade in the garbage decomposing tank is rotated and revolved at the same time, the stirring is performed uniformly, the stirring efficiency is improved, and the garbage decomposing capacity is further improved. improves.

There are various types of garbage in the lifestyle of each household, but there is an experimental result that most food waste can be easily decomposed by using the present invention. Even in the original form of the head of a large salted salmon, as well as the eggshell, fish bone, crab shell, etc., it becomes completely indistinguishable after one week. After a considerable period of time (about two months) after the garbage is thrown, nitrogen, phosphate, potassium, etc., such as the three major nutrients contained in the garbage, are adsorbed and accumulated in the garbage garbage decomposition agent, and fertilizer is added. It is a highly effective soil conditioner.

(3) The outside air is sucked from the groove in the gap between the garbage inlet and the garbage press-in unit, passes through the gap of the garbage decomposition medium, and reaches the opening of the top plate for intake. Since the air is discharged from the air outlet, the odor of the garbage attached to the inlet is also drawn into the treatment tank main body, and the odor from the inlet is completely eliminated.

(4) When the garbage is thrown in and the garbage feeding lid is closed, the garbage is automatically stirred together with the garbage decomposing medium in the treatment tank body, so that no human labor is required. Also, the operation is simple because the user only needs to open and close the lid.
