Description

  The present invention relates to a household garbage composting apparatus for processing and composting garbage generated from a household.

Conventionally, there are mainly the following methods for treating household waste, particularly raw garbage generated by cooking.
The most common garbage disposal method is a method in which the garbage is transported to a cleaning plant and incinerated in an incinerator. However, if only normal combustible waste is used, the furnace temperature is maintained at 700 ° C. or higher and stable combustion is performed. However, if garbage is contained, the furnace temperature decreases due to the moisture, and is not good. There is a problem that stable combustion occurs and dioxins are easily generated.
In addition, as another method for treating garbage, the method of directly burying garbage in the ground has a problem that a bad odor is generated due to decay, and further promotes the reproduction of harmful insects and is unsanitary.

  In recent years, attention has been focused on a method for composting, that is, composting household garbage. Composting mainly uses the action of aerobic microorganisms to decompose and reduce the organic matter in the garbage, and at the same time, reduces the amount of water in the garbage by the heat of fermentation accompanying the decomposition of the organic substance, and This method also performs sterilization of harmful bacteria. Compost is obtained by composting, and the compost can be effectively used to fertilize the soil. For composting, various devices and instruments are used for artificially preparing conditions under which microorganisms are likely to be active and promoting decomposition in a relatively short period of time (see Patent Documents 1 to 3).

  The aforementioned composting device, ie, the garbage composting device, is for promoting the life support and growth of microorganisms. Specifically, in order to maintain the reaction rate of the in-vivo enzyme of the microorganisms well, there are many containers having a structure that realizes maintenance of the optimum temperature, supply of oxygen, elimination of excess water, and the like. And most of the conventional garbage composting apparatuses proposed for home use plastic containers.

However, when garbage is treated in a plastic container, harmful insects are generated in the container, especially in the hot season, and a strange odor can enter. If you try to add garbage to the container in such a state, you will endure discomfort and bad odor, and you will end up getting tired of using the device.
Many of them are equipped with complicated electric and mechanical mechanisms for maintaining the temperature of the container, ventilating, adjusting the amount of water, stirring, etc., but these are very expensive products.

Therefore, in order to solve the problems of the conventional composting apparatus, that is, the garbage composting apparatus, there is a demand for a garbage composting apparatus suitable for home use that satisfies the following conditions (requests).
(1) It is possible to maintain the conditions for promoting composting of garbage without using complicated electrical and mechanical mechanisms and to obtain compost.
(2) It must be compact and installable in a narrow place.
(3) The manufacturing cost of the garbage composting apparatus itself is low and the operation cost is low.
(4) There is little work effort for processing, and it can process easily.
(5) Be clean (no odor and no harmful insects)

The applicant of the present application has already applied for a household garbage composting apparatus to satisfy the above-mentioned demand (see Patent Document 4). The household garbage composting device of Patent Document 4 includes a cylindrical body composed of a cylindrical paper tube provided with a plurality of stirring rods therein, a side surface portion, a fermentation container having a removable lid portion, a compost receiving tray, An installation base having a plurality of rollers for rotatably supporting the cylindrical body portion and a wedge for fixing the rotation of the fermentation vessel are provided.

Hereinafter, embodiments of the present invention will be described with reference to the drawings showing examples.
FIG. 1 is an overall perspective view of a household garbage composting apparatus 1 according to the present invention.
FIG. 2 is a longitudinal sectional view of the household garbage composting apparatus 1.
1 and 2, the household garbage composting apparatus 1 inputs raw garbage generated by cooking or the like at home and mixes it with a culture material containing microorganisms and nutrients to ferment the raw garbage. It is a device for decomposing and composting.

The household garbage composting apparatus 1 includes a fermentation container 2 that accommodates the garbage 31, and an installation base 3 that is installed below the fermentation container 2 and serves to support the fermentation container 2 rotatably.
The fermentation vessel 2 includes a cylindrical body 4 in which a cylindrical paper tube is disposed sideways (a direction in which the rotation axis is horizontal), and a pair of disk-shaped side portions that closes the left and right ends of the cylindrical body 4 in a sealed state. 5 and 5 and a lid portion 7 for closing the charging port 6 formed in a part of the cylindrical wall of the cylindrical body portion 4.

A cylindrical paper tube is used for the cylindrical body portion 4, but the side surface portion 5 is also preferably formed by processing a paper plate into a disk shape.
Further, the outer peripheral edge 5 a of the side surface portion 5 is configured to extend outward from the outer peripheral surface of the cylindrical body portion 4 over the entire periphery. That is, the outer circumferential circle of the side surface portion 5 is configured to have a larger diameter than the outer circumferential circle of the cylindrical body portion 4.

3 is a cross-sectional view taken along the line A-B-C-D in FIG. 2. In FIG. 3, 8 penetrates through the center of the cylinder part 4 and closes both end openings of the cylinder part 4 respectively. The bolts 8 are formed as headless bolts having screws threaded at both ends, and the side portions 5 and 5 are attached to the bolts 8 and both ends of the bolts 8. The wing screws 9, 9 are in pressure contact with the opening portions at both ends of the cylindrical body portion 4 and are detachably attached.
And the fermentation container 2 can be disassembled by removing the thumbscrews 9 and 9. That is, the pair of side surface parts 5 and 5 can be removed, and the inside of the cylinder part 4 can be opened.

  The insertion port 6 is formed by cutting a part of the cylindrical wall of the cylindrical body portion 4 into a predetermined contour shape, which is a rectangular shape in the drawing. A plate-like or sheet-like seal 10 is provided between the outer peripheral edge of the insertion port 6 and the lid portion 7 to ensure a sealed state. The seal 10 is attached to either the outer peripheral edge of the insertion port 6 or the lid portion 7.

  The installation base 3 includes a flat base plate 21 and four support rollers 22, 22... Projecting from the base plate 21. The support roller 22 is a roller projecting from the upper surface of the base plate 21. The support 21a is rotatably supported by the shaft. These support rollers 22, 22...

In the illustrated example, support rollers 22, 22... Are arranged so as to be in contact with the outer peripheral surface of the cylindrical body portion 4 in the vicinity of the inner sides of the side surface portions 5, 5 of the cylindrical body portion 4.
The rotating shaft of the support roller 22 is attached so as to be parallel to the rotating shaft of the cylindrical body portion 4. As described above, by supporting the fermentation vessel 2 on the support rollers 22, 22..., It is possible to manually rotate the cylindrical portion 4 of the fermentation vessel 2 manually. It can be rotated in either the forward or reverse direction.

  The cylindrical paper tube constituting the cylindrical body 4 is manufactured, for example, by rotating three mandrel appropriately arranged around the mandrel while spirally rotating the mandrel (iron core), although illustration is omitted. The A tube wall of a cylindrical paper tube is formed by three strips. They are bonded together by applying an adhesive to a part of each strip. It should be noted that an adhesive for adhering a plurality of paper layers of a cylindrical paper tube may be partially used in such a minimum amount as not to impair air permeability. The cylindrical paper tube that is wound and formed on the tube wall of the three-layer structure is extracted from the mandrel and cut into a desired length by a cutter to form the cylindrical body portion 4.

  For cylindrical paper tubes, a wide variety of products are commercially available depending on the purpose of use, such as diameter, length, paper quality, number of paper layers, thickness, strength, etc., and desired properties according to the order. Since the paper tube is generally manufactured, it is possible to easily select one having characteristics and dimensions suitable for the present invention.

FIG. 4 is an enlarged cross-sectional view of the main part of the lid portion 7. As shown in FIG. 4, the lid portion 7 is made of a transparent plate and is attached to the input port 6 so as to be freely opened and closed.
In the figure, 11 is a hinge for attaching the lid portion 7 to the cylindrical body portion 4 so as to be openable and closable, and 12 is a locking tool for locking the lid portion 7 to the cylindrical body portion 4.
The insertion port 6 is formed by cutting a part of the cylindrical wall of the cylindrical body part 4 into a predetermined contour shape, and it is preferable to use the piece cut at this time as the lid part 7 as it is.

Next, the usage method of the household garbage composting apparatus which concerns on this invention is demonstrated for every process according to FIG.
First step: The lid portion 7 of the fermentation vessel 2 is opened (indicated by a two-dot chain line in the figure), and garbage 31 is introduced from the inlet 6 as shown by arrow E, and an appropriate amount of culture material (not shown) is sprayed on this. The total amount of garbage 31 can be adjusted by the amount of the culture material. As the culture material, peat moss, firewood charcoal (raw rice husk), microorganism group (EM fungus), sawdust, etc. are suitable. It is more effective to add rice bran or deteriorated tempura oil.

Second step: After closing the lid portion 7 and locking with the locking tools 12 and 12 and closing the charging port 6 (shown by the solid line in the figure), the fermentation vessel 2 is rotated several times, and the internal garbage 31 And the culture material are stirred and mixed uniformly.
In addition, as many times as a day, whenever the garbage 31 is generated, it is put into the fermentation container 2 and rotated several times each time. The reason for rotating is to stir well the garbage 31 thrown in this time and the garbage 31 thrown in last time.

Third step: Leave for a predetermined period. During this time, the garbage 31 is decomposed by the action of microorganisms, and water vapor and carbon dioxide (not shown) are generated. However, it is preferable to rotate appropriately from time to time. Thereby, since the position where the garbage 31 contacts the cylinder part 4 inner surface can be changed, deterioration of the cylinder part 4 can be delayed and a lifetime can be extended. And after confirming that the thrown-in food waste composted by visual observation from the cover part 7, the pair of side surface parts 5 and 5 of the fermentation container 2 are removed, and the compost in which the food waste 31 changed is discharged | emitted. Thus, compost can be obtained from the garbage 31.
In the second step, the fermentation vessel can be directly placed on the floor surface or the ground and rotated without using the installation base 3.

The compost thus obtained can be used as a fertilizer after being mixed with soil in a field or the like for about one month.
The period from the first step to the third step is about one year when the amount of culture material is about one year. For about one year, every time the garbage 31 is generated, it can be continuously put into the fermentation vessel 2.
In addition, in the first step to the third step, in order to promote the activity of microorganisms responsible for composting, it is necessary that the outside air temperature is 10 to 40 ° C. (preferably 15 to 20 ° C.).

  Moreover, in the said household garbage composting apparatus 1, it is also possible to make the installation base 3 for supporting the fermentation container 2 unnecessary. At that time, instead of rotating the fermentation vessel 2 on the installation base 3, if the fermentation vessel 2 is directly rotated on the floor or the ground, the fermentation vessel 2 can be attached to the side portions 5 and 5. The outer peripheral edges 5a and 5a rotate in contact with the floor surface or the ground, and an effect substantially similar to the effect of the installation base 3 can be obtained.

  In addition, when the household garbage composting device of the present invention was installed in a kitchen and used, as a garbage composting device, no foul odor leaks and no harmful insects are generated, and smooth composting is performed in a clean state. Etc., very good results were obtained. In addition, it is convenient because the generated garbage can be immediately put into the apparatus for processing.

  In the household garbage composting apparatus 1, the cylindrical portion 4 is formed of a cylindrical paper tube, but may be formed of a cylindrical wooden tube instead of the cylindrical paper tube. Similar effects can be expected.
