TECHNICAL FIELD OF THE INVENTION
The present invention relates to an improvement in a garbage disposal apparatus that treats garbage with microorganisms.
[0002]
[Prior art]
Recently, garbage processing apparatuses that can easily process garbage in ordinary households due to the problem of the garbage disposal capacity of each local government are becoming widespread. As the garbage processing apparatus, there are a garbage processing apparatus that can reuse garbage as a fertilizer, and a garbage processing apparatus that almost completely removes 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 processing apparatus using microorganisms has the advantages that almost all of the input garbage is eliminated and that odors and insects are not generated, and it is a factor that can be easily introduced without much labor. It is particularly useful for condominiums and other condominiums, and recently there are condominiums and detached houses equipped with such a processing device as standard.
[0004]
[Problems to be solved by the invention]
However, a conventional garbage processing apparatus using microorganisms generally includes a processing tank for storing a decomposition medium material containing microorganisms and garbage, and a stirring device for stirring the decomposition medium material and garbage inside the processing tank. At present, the apparatus itself has to be expensive. It is considered that this factor is mainly due to the structure of the conventional stirring device. In the garbage processing method using microorganisms, it was necessary to mix the decomposition medium material and the garbage and to supply oxygen by periodically stirring the decomposition medium material and the garbage in order to enhance the processing capacity. . For this reason, in the garbage disposal apparatus using microorganisms, although the stirring device is indispensable, the structure is too complicated.
[0005]
A conventional general stirrer has a structure in which a rotating shaft is provided inside a processing tank and stirring blades are attached to the rotating shaft to perform stirring. Therefore, the processing tank needs to be integrally molded by plastic molding or the like in order to hold the stirring device inside, which is expensive. In addition, there are various problems such as sealing between the processing tank and the rotating shaft, installation of a stirrer in the processing tank, strength of the processing tank for rotatably supporting the stirrer, and the cost is high. It will be. Further, there is a problem that maintenance such as cleaning the inside becomes difficult due to the presence of the stirring device inside the processing tank.
[0006]
[Means for Solving the Problems]
In view of the above problems, the present inventor has accomplished the present invention as a result of intensive research, and the feature of the present invention is that in a treatment apparatus for treating garbage with a decomposition medium material containing microorganisms, the decomposition is carried out. At least a bottom portion of the processing tank for storing the garbage as a medium material is formed of an outer member and a flexible portion formed of a soft material having air permeability and at least partially moved inward by a mixing device. A double structure constituted by an inner member provided in a portion, wherein air is blown between the inner member and the outer member by a blower.
[0007]
Here, the term "decomposition medium material" as used herein refers to a carrier holding soil microorganisms or the like that decompose proteins and cellulose. The carrier is, for example, wood chips, wood flour or peat moss. The garbage is decomposed by mixing and stirring the decomposition medium and the garbage. The garbage is decomposed by the microorganisms into carbon dioxide and water vapor, and most of the garbage disappears.
[0008]
The “treatment tank” refers to a container or a bag-shaped container for storing a decomposition medium material, mixing garbage into this portion, and mixing the garbage to decompose the garbage. In the present invention, at least a bottom portion of the processing tank has a double structure including an inner member and an outer member. Of these, at least the inner member is formed at least in part of a material having air permeability or a material provided with air permeability, and at least a bottom portion is provided with a soft portion formed of a soft material. In this case, the outer member may be formed entirely of a steel plate such as plastic or stainless steel, or may be formed of a soft material for the entire or bottom portion.
[0009]
As such a treatment tank, for example, a combination of an inner tank having air permeability and having a soft portion at least in a bottom portion and an outer tank having a soft portion at least in a bottom portion, or a conventional treatment tank, This is a case where an inner bag having gas permeability and having a soft portion at least in the bottom portion is loaded in the tank. In addition, the processing apparatus body may be provided with an exterior part formed of a non-permeable member such as plastic or stainless steel, and may have a structure that partially covers the outer surface side of a processing tank having permeability and at least a soft part at a bottom part.

The “soft part” refers to a part of the inner member such as the processing tank or the inner bag formed of all or a part of the soft material. In the present invention, the inner member of the double structure portion needs to have air permeability. In other words, this is because oxygen is supplied to the decomposition medium material through the air-permeable inner member by sending air between the double structure portions. The portion for providing air permeability to the inner member is not particularly limited as long as it is provided on the entire inner member. However, it is preferable to provide it in a soft portion which is a portion for containing and mixing the decomposition medium material. The flexible portion having air permeability may be formed of a material having air permeability, such as the above-described cloth such as canvas, or may be a non-permeable plastic sheet or the like which is partially provided with air holes to allow air to flow. . In the case where the flexible portion is provided on the outer member of the double structure portion, it is not particularly limited, but it is preferable that the flexible member be formed of a non-permeable soft material in order to improve the permeability of the inner member.

Further, a heat insulating material may be provided between the double structure portions. The heat insulating material is used to insulate the contents such as the decomposition medium material charged into the processing tank and the inner tank. In the present invention, the double structural portion may be integrally deformed by the mixing device, and in such a case, it is necessary to use a heat insulating material that can cope with the repeated deformation. When only the soft portion of the inner member is moved inward by the mixing device, use a shape-preserving heat insulating material or separate the heat insulating material with a net or a breathable member. Need to be retained. In any case, the heat insulating material needs to have a structure that allows at least the supplied air to reach the entire double structure portion. As the heat insulating material, any member may be used as long as the air layer is made resident by keeping the space between the double structural parts, for example, glass wool, sponge, non-woven fabric, a plurality of protrusions, a net, a three-dimensional net. And so on. In addition, a plurality of protrusions or ribs may be integrally formed on the outer surface of the inner member or the inner surface of the outer member.
[0014]
"Mixing device" refers to a device for moving at least a part of the flexible portion of the inner member inward. That is, any material may be used as long as at least the soft portion of the inner member is pushed inward or pulled up to mix the stored decomposition medium material and garbage. As the mixing device, for example, a pressing tool that moves up and down is disposed below the processing tank and the inner tank, and the contents are mixed by pushing up and down the soft part of the processing tank and the inner bag with the pressing tool. . Further, the mixing device may be arranged on the side of the processing tank or the inner tank and pressed from the side, or a string, a wire, a chain, or the like is provided at the bottom of the processing tank or the inner tank, and these are provided. It may be of a structure that can be lifted. The mixing device may be provided only at one place, or may be provided at a plurality of places and operated simultaneously or alternately.

If the heater 17 is provided in the air blowing port 7 between the outer bag 5 and the inner bag 4, the entire area of the double structure portion can be heated simply by blowing in the air. Needless to say, the same effect can be obtained by providing the heater 17 on the pressing tool 11 side, or by providing the heater 17 on the surface of the outer bag 5 as shown in FIG.
[0026]
In the use state of the garbage processing apparatus 1 according to the present invention, since the processing tank 2 is provided separately from the mixing apparatus 10, the processing tank 2 can be easily removed from the processing apparatus 1. In this case, if the blower port 7 and the blower duct 18 can be connected when the processing tank 2 is placed on the pressing tool 11 as in the above-described example, it takes almost no time to attach and detach the processing tank 2. Even if the duct 20 is connected to the air outlet 7, the duct 20 may be lengthened or may be detachable with a single touch as shown in FIG. Can be easily performed. In this case, if the inner bag 4 can be removed from the outer bag 5, regardless of the outer bag 5 to which the duct 20 is connected, only the inner bag 4 is removed from the processing apparatus main body as shown in FIG. Disposal and the like can be performed.
[0027]
Although each of the above-described examples shows an example in which each of the outer member and the inner member of the processing tank 2 is formed of a soft member, only the inner member may be formed of a soft member.
