Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improved garbage disposal apparatus and method for treating garbage with microorganisms.

[0002]

2. Description of the Related Art Recently, garbage disposal apparatuses that can treat garbage for industrial use such as food and drink industry, poultry raising industry and pig raising industry have become widespread due to the problem of garbage disposal capacity of local governments. . As the garbage disposal apparatus, there are a garbage disposal apparatus capable of reusing garbage as fertilizer, and a garbage disposal apparatus capable of eliminating most of the garbage by microorganisms.
Among these, as for the garbage processing apparatus using microorganisms, microorganisms can be easily obtained in recent years due to the development of biotechnology, and various apparatuses are sold by home electric appliance manufacturers and the like.

[0003] The treatment apparatus utilizing microorganisms has an advantage that most of the raw garbage introduced is treated by microorganisms and can be easily introduced without any labor. This type of processing apparatus is useful for apartments and other apartment buildings and restaurants close to residential areas, and is also used for industrial and commercial purposes because it can be made larger.

[0004]

However, in the treatment of garbage by microorganisms, even if there is no odor, the odor is not so small immediately after putting in the garbage or until the garbage is processed. Met. Such a processing apparatus is often installed in a kitchen for convenience, and even a slight odor is a concern. Therefore, it must be installed outside the room, and the convenience is greatly impaired, and it is often not used at all at the end. Especially,
In a condominium or the like, there are many restrictions on the installation location outside the room, and in some cases, it may not be possible to install the garbage disposal apparatus at all. As a factor of the bad odor, in addition to the odor generated from the garbage itself, a fermentation odor when the garbage is decomposed by microorganisms can be considered. For this reason, conventionally, a countermeasure was taken by providing a deodorizing device or the like, but new problems have arisen, such as an increase in cost and a time-consuming replacement of the deodorant.

In the conventional processing apparatus, since the processing tank for storing the garbage is formed in a container shape from plastic or metal, the odor is easily trapped inside the processing tank, and the lid of the input section is easily trapped. There is a structural drawback in that the odor is emitted at the time of opening and closing. Furthermore, since the inside of the treatment tank has no air permeability and is structured to be stirred by a stirrer provided therein, the decomposition medium material and garbage become clay-like by stirring, and decomposition by microorganisms is hindered, It also caused the generation of putrefaction odor due to putrefaction.

[0006]

In view of the above problems, the present inventor has accomplished the present invention as a result of intensive studies. In a treatment apparatus for treating garbage with a decomposition medium material containing microorganisms, the stored contents are stirred by moving at least a part of a bottom part formed of a soft material and having air permeability and another part relatively up and down. A garbage storage container, a medium material storage container for storing the decomposition medium material, and an air suction device connected to the medium material storage container and sucking air in the garbage storage container through the filled decomposition medium material. That you did. Alternatively, in a processing apparatus for processing garbage by a decomposition medium material containing microorganisms, a structure in which at least a part of a bottom portion formed of a soft material and another portion are relatively moved up and down to stir the stored items. A measuring device for measuring the temperature inside the garbage container, and a control device for controlling the stirring device for the garbage container based on the value measured by the measuring device.

Further, according to the invention of the method, in a treatment method for treating garbage with a decomposition medium containing microorganisms, at least a part of a bottom part formed of a soft material and another part are relatively vertically moved. Based on the temperature inside the garbage storage container with a structure that stirs the stored items by
An object of the present invention is to control a stirring device of the garbage storage container so as to suppress decomposition heat.

[0008] Here, the "decomposition medium material" referred to in the present specification.
The term “carrier” refers to a carrier that holds soil microorganisms that degrade proteins, cellulose, and the like. The carrier is, for example, wood chips, wood flour or peat moss. The garbage is decomposed by mixing and stirring the decomposition medium material and the garbage. The garbage is decomposed into carbon dioxide gas and water vapor by microorganisms, and most of the garbage disappears.

The "garbage storage container" refers to a container or a bag-like container into which garbage is put. In the present invention,
At least the bottom portion is formed of a soft material and has a structure having air permeability. This container may be formed entirely of a soft material, or the upper frame and the cylindrical portion may be formed of a steel plate such as plastic or stainless steel, and the bottom portion formed of a soft material may be connected. Further, the inside of the container may be divided into a plurality of portions, or a plurality of containers may be provided in parallel.

[0010] The garbage storage container is usually filled with a decomposition medium material, and garbage is charged into the container for decomposition.
Alternatively, the garbage container may not be filled with the decomposition medium material, but may be brought into contact with a decomposition medium material filled in a medium material container described later. Stirring of the stored items in the garbage storage container is performed by moving at least a part of the bottom part and the other part relatively up and down. That is, in addition to lifting the bottom portion from below and pulling it from the inside, fixing the bottom portion and moving the upper portion of the storage container up and down, and simultaneously moving the bottom portion and the other portion up and down in the opposite direction Is the case. When the container is lifted from below, a pressing member is provided at a lower portion of the storage container, and the pressing member is driven so that at least a part of the bottom portion moves up and down.

As a method of pulling up the bottom portion of the storage container, for example, a string, a wire, a chain, or the like is connected, and this is stirred by moving it up and down. When the upper portion of the storage container is moved up and down, it is pushed up from below or suspended from above with a wire or a chain. As the soft material, for example, rubber, fabric such as canvas,
Any member, such as a sheet of polyvinyl chloride or polyethylene, a nonwoven fabric, a net, or a composite material thereof, which has flexibility and has sufficient restorability to stirring can be used.

In the stirring of the apparatus of the present invention, since a part of the storage container is moved up and down in a state where the storage items are stored, the weight may be in ton units for business use.
Requires considerable power. In such a case, a plurality of storage containers may be provided to reduce the weight of each storage container. When a plurality of storage containers are provided, the stirrer may be agitated by a vertically moving device that moves like a seesaw or a balance in which one is lowered when the other is lowered. The use of the vertical movement device has the advantage that the other storage device can be moved up and down using the weight of one processing device, and can be agitated with small power. For this reason, it is possible to operate even a large-scale machine for business use using a solar cell as a power supply. In the case of using the vertical movement device, a structure in which the inside of the storage container is divided into a plurality of parts is effective.

The garbage storage container may store garbage directly in the garbage container, or may store garbage in a separate bag. The material of the bag may be basically the same as the soft material described above, but it is convenient to carry out the entire bag when discarding the stored material, so that the sheet is made of inexpensive polyvinyl chloride or polyethylene. Is preferred. When a separate bag is used, the bag may be fixed with a hook-and-loop fastener or an adhesive so as not to move during stirring.

"Medium storage container" refers to a container for storing a decomposition medium. The medium storage container is provided so as to cover the air-permeable portion of the food storage container, and the air in the food storage container is brought into contact with the decomposition medium material by suctioning the intake device connected thereto. And exhaust it. In addition, if the processing apparatus main body has a sealed structure, the medium storage container may be provided anywhere inside the sealed portion, and the structure is not limited. In short,
Any material may be used as long as the air in the garbage storage container can be exhausted from the air-permeable portion through the decomposition medium material.

When the medium material storage container is provided so as to cover the air-permeable portion of the food waste storage container, the medium material storage container may be formed in a container or bag shape that covers the whole food waste storage container, and may be formed at the bottom portion of the food waste storage container. It may be tray-shaped or dish-shaped to cover only.
Further, in the case of a structure in which the upper portion of the garbage container is moved up and down to stir, the bottom may be formed in a columnar shape or a prism shape to support the bottom portion of the garbage container. The material may be formed of plastic, metal, or the like, or may be formed in a bag shape with cloth, rubber, or the like.

The "suction device" refers to a device for sucking air inside the garbage storage container through the decomposition medium material filled in the medium material storage container, thereby sucking the odor inside the garbage storage container. Examples of the intake device include a fan, an exhaust fan, and a vacuum pump. In addition to always operating the intake system,
It may be operated periodically or linked with a humidity sensor or a temperature sensor provided in the garbage container. The air containing the odor sucked in by the air intake device is deodorized by contacting the decomposition medium material, and is discharged with almost no odor.

"Measurement device" refers to a device for measuring the temperature in the garbage storage container. The temperature inside the garbage container is
The temperature may be measured by providing a temperature sensor inside or outside the storage container, or the temperature of the exhaust gas from the storage container by the intake device may be measured. The control device controls the stirrer based on the value measured by the measuring device. Alternatively, the outside air temperature may be measured by a measuring device, and the stirring device may be controlled based on the temperature difference from the temperature in the garbage storage container. In this way, by controlling the stirring device based on the temperature in the garbage storage container or the temperature difference from the outside air temperature, the heat of decomposition of garbage by microorganisms can be suppressed. In other words, the decomposition heat is the fermentation heat when the garbage decomposes,
By suppressing the fermentation heat, it is possible to reduce the fermentation odor which is one of the causes of the offensive odor.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail based on an embodiment shown in the drawings.

FIG. 1 shows an example of an embodiment of a garbage disposal apparatus 1 according to the present invention, in which a canvas, which is a soft material, is sewn inside a medium material container 2 having air permeability at the bottom. The garbage storage container 3 formed in this way is provided. The garbage storage container 3 is filled with a decomposition medium material 4, and the garbage 5 is put into the garbage for decomposition. The medium storage container 2 is also filled with the decomposition medium 4 so as to cover the air-permeable portion. Stirring of the stored items by the garbage disposal apparatus 1 is performed by moving the wire 6 connected to the bottom of the garbage container 3 up and down. That is, by repeating the state in which the bottom is pulled up by the wire 6 from the state shown in FIG. 7A to the state shown in FIG.

The medium material container 2 has a structure in which only the bottom portion has air permeability by being formed of canvas and the bottom portion being made of mesh. An air intake device I is connected to the air-permeable portion of the bottom, and air inside the garbage storage container 3 is sucked from the medium storage container 2 through the decomposition medium 4. Fresh air is supplied into the garbage storage container 3 by the suction by the air suction device I, and the odor generated from the garbage 5 is prevented from scattering. Further, when the sucked air comes into contact with the decomposition medium material 4 filled in the medium material storage container 2, the decomposition medium material 4 serves as a filter to remove most of the odor, and is released to the atmosphere in a deodorized state. Will be.

In the embodiment of the stirring structure of the garbage disposal apparatus 1, the wire 6 connected to the bottom of the garbage container 3 is moved up and down by a drive motor M as shown in FIG. The medium material storage container 2 shown in this embodiment is formed by plastic molding as shown in the figure. When replacing the disassembled medium material 4 filled in the medium material storage container 2, the garbage storage container 3 is first removed, and then the medium material storage container 2 is removed from the apparatus main body 7. In this case, it is preferable to use a flexible duct such as a bellows for the duct 8 connected to the intake device I, or to make the connecting portion to the bottom of the medium material storage container 2 easily detachable. Also, as shown in FIG. 1, if the medium material storage container 2 is formed in a bag shape with canvas or the like, it becomes inexpensive. Therefore, all of the medium material storage container 2 and the garbage storage container 3 are exchanged. Is also good.

As another embodiment of the stirring structure of the garbage storage container 1 according to the present invention, a medium storage container 2 is provided below the garbage storage container 3 as shown in FIG. With the storage container 2 supporting the bottom of the garbage storage container 3, the upper end of the garbage storage container 3 may be moved up and down to stir. In this case, the garbage storage container 3 of the device main body 7
Is closed, and suction is performed by the suction device I provided at the bottom of the medium storage container 2. Further, in this example, when the garbage storage container is lowered by making the top of the medium material storage container 2 projecting, the stored material does not remain on the top.

As another example of the embodiment of the garbage disposal apparatus 1 according to the present invention, as shown in FIG. 4, a temperature sensor 9 is attached to the outer bottom of the garbage storage container 3 and the value measured thereby is measured. This is input to the control device 10 to control the drive motor M of the stirring device. The purpose of controlling the stirring device by the temperature sensor 9 is to reduce the fermentation heat generated during the decomposition of the garbage 5 to suppress the fermentation odor generated during the fermentation.
For example, when the temperature of the garbage container 3 exceeds 20 ° C., the drive motor M is activated and the temperature inside the garbage container 3 is lowered by stirring. When the temperature is lowered, the rate of the decomposition treatment is reduced, but the fermentation is suppressed and the fermentation odor is almost eliminated, so that the source of the malodor can be cut off.

Since only the absolute temperature measurement in the garbage disposal container 3 depends on the installation period and the winter season and the summer season, the temperature is controlled based on the temperature difference from the outside air temperature as shown in FIG. Is also good. In the case of this example, the garbage disposal container 3
A temperature sensor 9 is provided in a duct 8 connected to the intake device I to measure the internal temperature based on the exhaust gas temperature. As described above, if the exhaust gas temperature is measured, the measurement can be performed without attaching the temperature sensor 9 to the garbage storage container 3 that is moved up and down and stirred, so that disconnection of the lead wire 11 can be prevented. Then, an external air temperature is measured by providing another temperature sensor 9 outside the device main body 7, and the control device 10 controls the stirring device based on a temperature difference calculated from the measured values of the two. The temperature difference should be kept within approximately 0 ° C to 7 ° C.

As another embodiment of the stirring method using the garbage container 3, as shown in FIGS. 6 (a) and 6 (b), the bottom and upper portions of the garbage container 3 are vertically moved in opposite directions. It may be. In this way, the moving distance in the vertical direction can be reduced, and the stirring efficiency can be increased to ensure the stirring.
