Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an improvement of a garbage disposal apparatus for treating garbage with microorganisms.
[0002]
[Prior art]
Recently, due to the problem of garbage disposal capacity of each local government, garbage disposal apparatuses that can treat garbage not only for general households but also for industrial use such as food and beverage industry, poultry farming and pig farming are becoming widespread. As a garbage disposal apparatus, there are an apparatus that makes it possible to reuse garbage as fertilizer, and an apparatus that eliminates most of the garbage by microorganisms. Among them, a garbage processing apparatus using microorganisms has recently become readily available due to the development of biotechnology, and various apparatuses are sold by home appliance manufacturers and the like.
[0003]
A processing apparatus using microorganisms has advantages that most of the input garbage disappears and that no odors or insects are generated, which is a factor that can be easily introduced without much trouble. It is particularly useful for apartment houses such as condominiums and restaurants in the vicinity of residential areas, and recently there are apartments and detached houses that are equipped with this processing device as standard equipment.
[0004]
[Problems to be solved by the invention]
However, in the method of treating garbage with microorganisms, the processing capacity is greatly affected by the type, input amount, and input frequency of garbage, and even though it has excellent functions for garbage treatment, However, it was difficult to fully utilize its functions. This is considered to be mainly due to the fact that the progress of garbage decomposition is difficult to judge objectively. For example, in a conventional garbage processing apparatus using microorganisms, a decomposition tank containing normal microorganisms and a processing tank for storing garbage are provided, and an agitator for stirring the decomposition medium and garbage in the processing tank. It was comprised, and it was only what was grasping | ascertaining the process condition with time progress only by stirring with a stirring apparatus regularly.
[0005]
Further, in the conventional processing apparatus, there is a processing apparatus provided with a humidity sensor or the like for the purpose of preventing the storage medium such as the decomposition medium material and the garbage in the processing tank from becoming a clay or drying. However, the humidity sensor can measure only a partial moisture content of the stored item due to its property, and there is a problem that the entire moisture content inside the treatment tank cannot be grasped. Moreover, it is impossible to mix the whole by simply stirring with a stirrer provided inside the treatment tank, in particular, moisture tends to accumulate in the lower part of the treatment tank, and the moisture content varies depending on the measurement site. Become. For this reason, in the judgment based on partial measurement values, means such as temperature setting and water addition for the purpose of displaying the input timing of garbage and activating microorganisms will be adversely affected. .
[0006]
Furthermore, there is a method of measuring the weight with a weight sensor or the like as means for grasping the entire state in the processing tank. Since most of the garbage is decomposed into water and carbon dioxide by biodegradation, this moisture is accumulated in the treatment tank, and the weight increases as the treatment of the garbage proceeds. And after that, water tends to evaporate and become dry and light. However, the conventional apparatus has a structure equipped with a stirrer inside the processing tank, and the processing tank itself is made of plastic or metal such as stainless steel, so the weight of the contents stored in it is measured. Was extremely difficult in terms of structure and technology, and was practically infeasible.
[0007]
[Means for Solving the Problems]
Therefore, the present inventor has achieved the present invention as a result of intensive studies in view of the above-mentioned problems. The feature of the present inventor is that in a processing apparatus for processing garbage with a decomposition medium material containing microorganisms, By forming at least the bottom portion of the processing container for storing the decomposition medium material and the garbage with a soft material, the stored item is agitated by relatively moving up and down at least a portion of the bottom portion and the other portion. In addition to the structure to be performed, there is provided a detection device that detects a change in the weight of at least the bottom portion of the processing container in which the stored item is stored.
[0008]
Here, the “decomposition medium material” in the present specification refers to a carrier holding a soil microorganism or the like that decomposes protein, cellulose and the like. Examples of the carrier include wood chips, wood flour, and peat moss. The garbage is decomposed by mixing and stirring the decomposition medium material and the garbage. Garbage is decomposed into carbon dioxide and water vapor by microorganisms, and most of it disappears.
[0009]
The “processing container” is a portion for storing a decomposition medium material, and refers to a container shape or a bag shape for putting garbage into the decomposition medium for decomposition processing. In the present invention, at least the bottom portion of the processing container is formed of a soft material. That is, the whole processing container may be formed of a soft material, or the upper frame or the cylindrical portion is formed of a steel plate such as plastic or stainless steel, and the bottom is formed of a soft material. Further, the inside of the processing container may be divided into a plurality of parts, or a plurality of processing containers may be provided in parallel.
[0010]
In the present invention, since the bottom portion of the processing container is formed of a soft material, another member may be provided for reinforcement. In this way, it is possible to sufficiently handle large machines for business use. However, when it is necessary to ensure the air permeability of the bottom portion, it is preferable to partially provide a reinforcing material. For example, a plurality of ropes and belts may be provided or wrapped with a net. In addition to directly storing the garbage in the processing container, the processing container may be configured to store the garbage in a separate bag. The material of the bag body may be basically the same as the soft material described later, but it is inexpensive because it is convenient to dispose of the bag body when disposing the contents, such as when the decomposition medium is outdated. A sheet of polyvinyl chloride or polyethylene is preferred. When using a separate bag, it may be fixed with a hook-and-loop fastener or an adhesive so that it does not move during stirring.
[0011]
As a processing container, it is good also considering the part formed with at least a soft material as a double or more composite structure. Various effects are produced by using a composite structure. For example, protection in the case where a portion storing raw garbage is torn, for keeping warm in the cold season, preventing the spread of odor by sucking air from the composite structure portion, supplying fresh air to microorganisms, and the like. The composite structure part may be moved up and down by being formed entirely of a soft material, or only the inner container may be moved up and down. For this reason, only the innermost container may be formed of a soft material, and the outer portion may be formed of plastic, stainless steel, or the like as in the past.
[0012]
In the conventional garbage processing apparatus, it is necessary to provide a discharge port at the bottom of the processing tank in order to remove the stored contents in the processing tank, for example, when the degraded decomposition medium material is replaced. However, in the present invention, the processing vessel is not equipped with a stirring device or the like, and has a structure in which stirring is performed by moving at least a part of the bottom portion formed of a soft material up and down, so that the processing vessel can be easily removed. This makes it very easy to remove and clean the stored items. In particular, if the decomposition medium material and the garbage are stored separately in a bag body made of polyethylene or the like, the bag body can be taken out and processed, and handling becomes even easier. However, the processing container in the present invention can be provided with an openable / closable opening at the bottom thereof, which is effective when the processing container is large. In addition, a partial discharge port may be provided in a part of the peripheral surface of the cylindrical portion at the top of the processing container so that contents such as seeds that cannot be decomposed are partially discharged. The cylindrical portion may be formed of a plastic molded product.
[0013]
The “soft material” refers to a member that has flexibility and has sufficient resilience against repeated deformation when formed into a bag shape. Examples of such a soft material include a fabric such as rubber and canvas, a sheet such as polyvinyl chloride, polyethylene, and polypropylene, a non-woven fabric, a net, or a composite material thereof. The soft material does not require water resistance or water retention, and any material that can store and hold the decomposition medium material and the garbage can be used. Moreover, you may make it raise the activity of microorganisms by providing a heater in the inside and surface of the part formed with the soft material, and heating. All or the bottom of the processing container is formed by molding or sewing into a container shape or bag shape with such a soft material.
[0014]
Stirring of the contents in the processing container is performed by relatively moving up and down at least a part of the bottom part of the processing container and the other part. This is because the bottom part is lifted from below, pulled up from the inside, the bottom part is fixed and the upper end part of the processing vessel is moved up and down, and the bottom part and other parts are moved up and down simultaneously in the opposite direction. This is the case. In the case of lifting from below, a pressing member is arranged in the lower part of the processing container, and this is driven so that at least a part of the bottom part moves up and down. The method of pulling up the inside of the processing container is performed by, for example, connecting a wire or chain from the processing container to the bottom and pulling it up. In this case, it is also possible to stir with a vertical movement device as described above using a pulley or the like. When the upper end portion of the processing container is moved up and down, it is pushed up from below or suspended from above by a wire or a chain.
[0015]
In the agitation by the apparatus of the present invention, a part of the processing container is moved up and down in a state in which the stored items are stored, so that it may be a ton unit weight for business use and requires considerable power. In such a case, a plurality of processing containers may be provided to reduce the weight of each processing container. In addition, when a plurality of processing containers are provided, stirring may be performed by a vertical movement device that moves like a seesaw or a balance that rises when one is lowered. If this vertical movement apparatus is utilized, the other processing apparatus can be moved up and down using the weight of one processing apparatus, and there exists an advantage which can be stirred with small power. For this reason, even a large machine for business use can be operated with a solar cell as a power source. In the case of using a vertical movement device, a structure in which the inside of the processing container is divided into a plurality of parts is also effective.
[0016]
The “detection device” refers to a device that detects a change in the weight of at least the bottom portion of the processing container in which the stored item is stored. Examples of the detection device include a pressure transducer and a pressure sensor. Thus, the weight of the bottom portion of the processing container is detected as a pressure, and this is converted into a voltage or current that is an electric quantity, thereby controlling the stirring device, the heater, or the like. Moreover, the ammeter etc. which detect the electric current value of the drive motor of a stirring apparatus as a detection apparatus may be used. That is, it is a method of grasping the internal state of the processing container by the driving resistance of the stirring device.
[0017]
“Biosolution” refers to a liquid solution containing microorganisms for treating garbage. For example, the bottom part of the processing container is immersed in a solution containing about 10 ¹⁰ / cc of microorganisms such as a high concentration bio solution, and the microorganisms are supplied to the inside through the bottom part. The bio-solution may be adjusted to culture conditions such as addition of nutrients such as medium and molasses, oxygen supply, and the like.

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, the present invention will be described in detail based on embodiments shown in the drawings.
[0019]
FIG. 1A shows an example of an embodiment of a garbage processing apparatus 1 according to the present invention, in which a pressure sensor is provided at a substantially central portion of a lower portion of a processing container 2 formed by molding rubber which is a soft material. 3 is provided. The agitation method of the garbage processing apparatus 1 is performed by connecting the wire 4 from the inside of the processing container 2 to the bottom portion thereof and moving the wire 4 up and down by the drive motor M as shown in the figure. Accordingly, it is possible to measure the weight very accurately by providing a structure in which the bottom portion of the processing container 2 formed of a soft material is moved up and down and stirred, and the pressure sensor 3 is provided in the lower portion thereof. Moreover, it can implement similarly even if the pressure sensor 3 is provided in the pressing tool 5 made to stir from the lower part of the processing container 2 like the figure (b).
[0020]
The measurement data obtained by periodically measuring the weight of the processing container 2 with the pressure sensor 3 is used as a judgment material for the processing status of the garbage by temporally judging the comparison between the increase amount and the decrease amount. For example, the reduction data after throwing in the garbage is compared with the optimum data by the microcomputer, and the determination of the decomposition ability is displayed as a numerical value, or is displayed as an indicator as a biocondition. It can also be used to display warnings, warnings, bio supply, and media replacement time due to abnormal values. Furthermore, as a preventive measure against overhumidity, the air volume of the blower for ventilation or exhaust can be adjusted early.
[0021]
As the detection device, in addition to the pressure sensor 3, the above-described display may be performed by data such as an ammeter that measures the current value of the drive motor 5. In this case, it is not necessary to provide the lower part of the processing container 2 like the pressure sensor 3. For example, a container filled with a biosolution or a stirring device that presses the bottom part of the processing container 2 from below is provided. Effective.
[0022]
FIG. 2 shows another example of the embodiment of the processing container 2, and a belt-like reinforcing band 6 is attached to the outer surface from the top to the bottom. In this example, a hole is formed in the bottom of the processing vessel 2, a part of the reinforcing band 6 is formed in a ring shape and protrudes into the inside, and a chain or a wire is hooked on this. The hole is sealed with the patch 7 from the outer surface side. Thus, by providing the reinforcing band 6, the strength of the processing container 2 becomes extremely high, which is effective for a large-sized machine having a large storage capacity for business use.
[0023]
The processing container 2 may have a triple structure as shown in FIG. 3 in addition to a simple double structure. In this case, the inner bag 8 is made of a fine air-permeable cloth so that the medium dust does not come out, and the outer bag 9 is made of a strong and breathable cloth so as to support the whole. A reinforcing band 6 may be further sewn on the outer bag 9. The inner partition member 10 is formed of a non-breathable cloth or plastic sheet, so that the sucked air easily flows from the top to the bottom of the processing container 2 and enhances the breathability of the stored items. is there.
[0024]
Further, as shown in FIG. 4, the processing container 2 is provided with an opening in a part of the upper peripheral surface and a mesh-like lid 11 is attached. Thereby, only the powder in the medium material in the processing container 2 is discharged from here by the vertical movement of the processing container 2 and stored in the dust bag 12 provided on the outer surface side. Moreover, if the lid | cover 11 is removed, the medium material in it can be discharged | emitted from an opening part, and replacement | exchange of a medium material will become easy. If the pressure sensor 3 is also provided on the cradle of the dust bag 12, the replacement time of the dust bag 12 can be displayed.
[0025]
FIG. 5 shows an example in which an electrode 13 is provided on the processing container 2 in order to measure the humidity of the stored item in the processing container 2. FIG. 6A shows a state where the processing container 2 is provided at an upper position that does not significantly affect the vertical movement of the processing container 2, and is for preventing disconnection of the lead wire 14. In this case, the electrode 13 is energized with the bottom of the processing container 2 lifted. And the humidity of a stored item is determined by measuring the resistance value. FIG. 2B shows the processing container 2 having a double structure, in which only the inner bag 8 is moved up and down. The electrode 13 is exposed to the inside and outside of the bottom of the inner bag 8 and is energized through an electrode plate 15 provided on the outer bag 9 that contacts the electrode 13 when the inner bag 8 is lowered. Structure.
[0026]
FIG. 6 shows still another example of the embodiment of the garbage processing apparatus 1 according to the present invention, in which the bottom portion of the processing container 2 is fixed and the top is moved up and down to stir the structure. is there. In the case of this example, the bottom portion of the processing container 2 is the discharge port 16. That is, the discharge pipe 17 is fixed to the discharge port 16 provided in the bottom portion, and the agitation is performed in a state where the stored items are stored at a position below the discharge port 16. When discharging the stored item, the stored item is discarded from the discharge pipe 17 through the discharge port 16 by raising the upper end of the processing container 2 so that the discharge port 16 is at the lowermost position.
[0027]
Such a structure can be implemented in the same manner even if the pressing tool 5 that presses the bottom portion of the processing container 2 from below is provided with the function of the discharge pipe 17. In these cases, if a lid is provided on the discharge port 16 or the discharge pipe 17, stirring can be performed above the discharge port 16. The lid may be a valve structure that can be opened and closed from the outside.
[0028]
FIG. 7 shows still another example of the embodiment of the garbage processing apparatus 1 according to the present invention. FIG. 7 (a) shows a vertically moving member that performs a seesaw motion on the lower part of each processing container 2 provided side by side. 18 is provided. In this case, the cam is rotated by the motor M so as to alternately move up and down. FIG. 4B shows a combination of the pulley 20 and the wire 4 that is moved up and down. In these cases, there is a difference in the processing speed of each processing container 2 depending on the type of garbage that is input. Therefore, if the vertical movement device 18 can be moved freely except during driving, the vertical movement The device 18 can be used as a sensor. For example, since the processing container 2 with the faster garbage disposal is lighter than the slower one, if the indicator lamp is lit on the ascending side of the vertical movement device 18, the one that is lit You can make it throw in garbage. Further, even when the vertical movement device 18 is driven, a difference occurs in the driving torque due to the difference in weight, and this may be detected. In this case, it is not necessary to leave it free. Further, when the vertical movement device 18 is used, the other processing container 2 is raised using the weight of one processing container 2, so that even a large machine can be driven with small power. Therefore, it is possible to use a solar cell as a power source, which is extremely useful from the viewpoint of energy saving.
[0029]
FIG. 8 shows still another example of the embodiment of the garbage processing apparatus 1 according to the present invention, in which a container 22 containing a bio solution 21 containing microorganisms is provided in the lower part of the processing container 2. is there. By immersing the bottom of the processing container 2 in the biosolution 21, microorganisms are supplied into the processing container 2. In this case, the bottom portion is formed of a material such as a cloth through which the biosolution 21 is transmitted. Normally, microorganisms are replenished to the decomposition medium material used as a carrier for microorganisms in the processing container 2, but the processing can be performed simply by putting garbage into the processing container 2 without interposing this decomposition medium material. Is possible.
