Description

The present invention relates to a simple and odorless organic waste composting and volume reducing device in the form of a water-permeable vertical cylinder.

The outline of the conventional technology and its problems are described below.
A simple composting and volume reduction device for organic waste called so-called garbage for household or personal use is commercially available. In one conventional example, an upside-down bucket-shaped plastic container with its bottom removed is placed on the ground, its upper opening is covered with a lid, and a compost outlet with a lid is provided at the bottom. In some cases, when the garbage is collected a little, the lid is opened and charged, and when the container is filled with compost, the compost is taken out from the lower outlet. In addition, the lid is provided with a pocket for holding a deodorant, and garbage fermentation promoters, deodorants, insecticides and the like are added as consumables (see, for example, Non-Patent Document 1). .

  However, composting of food waste has been slowed against expectations, filling containers in a short period of time, and complaining that food rots and stinks, causing discomfort to the family and the surrounding people Is often heard. This device has a sealed structure to prevent bad odors from leaking, and it is surmised that the main cause of this is a lack of air supply. Even if a lower outlet is provided, it is normally closed and the compost is compressed and stuck by the upper sediment, so it is difficult to take it out with a rake or the like, which is not very useful. Therefore, it was necessary to lift the entire container every time it was taken out.

Compost (garbage disposal container) manufactured by Iris Oyama Co., Ltd. Model No. IC-130

From the above, in order to eliminate the above-mentioned drawbacks of the prior art, the present invention is a simple and simple composting / reducing method using an inexpensive, permeable cylindrical body made of a concrete block or an inorganic sintered body. To provide a container.

  In order to achieve the above object, the organic waste composting and volume reducing device of the invention of claim 1 includes a water-permeable tubular body 50 formed in an upright tubular shape and an upper opening 51 of the tubular body 50. Covered with a roof 60 having a lid 61 for throwing in organic waste, a lower opening 52 for introducing air is provided in the lower part of the cylindrical body 50, and the lower opening 52 is thrown in above. While supporting solid waste made of organic waste or compost produced by fermentation thereof, air introduced from the lower opening 52 passes, and fine particles produced by composting the organic waste pass and fall. A possible lattice 70 is provided, and the cylindrical body (50) is a concrete block or a substantially rectangular parallelepiped-shaped concrete block made of a concrete block or an inorganic sintered body having a size that can be easily held by hand. Block (CB) is assembled It has been polygonal frame (F) is formed by stacked multiple stages so as to be tapered from the bottom to the top.

  In addition to the invention of claim 1, the invention of claim 2 is provided with a protrusion 17 projecting vertically and vertically on the side surface of one end of the concrete block CB in the longitudinal direction. When the square frame F is formed by the combination of the four concrete blocks CB, one of the two adjacent concrete blocks CB and CB is on the side where the protrusions 17 are not projected. An outer corner C1 of the end is configured to be fitted to an inner corner C2 of the base of the other protrusion.

According to a third aspect of the present invention, in addition to the configuration of the second aspect of the invention, the concrete block CB has one end of a rectangular parallelepiped main portion 11 having a reference length, the same cross section as the main portion 11, and an arbitrary section. The other end of the sub-portion 15 having a ridge 17 projecting in a hook shape perpendicular to the side surface thereof is joined directly or integrally through a connecting member J to one end of the rectangular portion 16 having the length of It is a thing.

  According to the first aspect of the present invention, the lower opening 52 is provided to the organic waste containing water, which is introduced from the upper part of the upright permeable cylindrical body, supported by the lower lattice 70, and deposited inside. Air necessary for the growth of aerobic bacteria is sufficiently supplied through the hollow and water-permeable cylindrical body constituting the cylindrical body 50, and excess water contained in the organic waste is discharged to the outside. Therefore, the organic waste that has been introduced from the upper part and has become appropriate moisture is fermented one after another by aerobic bacteria and composted. Accordingly, the organic waste containing water does not generate a foul odor associated with its decay, becomes reduced and finely composted, and falls from the lower lattice 70 to the opening 52. Can be easily removed.

  In addition, for example, for organic waste deposited in the central part of the water-permeable cylindrical body, a hollow tube having many small through holes on the side surface is provided on the lattice 70 in the water-permeable cylindrical body, for example. It is preferable that the air that has entered from the lower opening 52 is supplied to the organic waste through the many small through holes of the hollow tube, so that the composting is promoted. Further, for example, the upper opening 51 is not completely covered by the roof 60 but is provided with an air supply / exhaust port so that air can be supplied and exhausted. In addition, a net-like partition wall is provided so that no soot enters from there. Even if eggs are spawned unexpectedly due to the intrusion of cocoons, etc., when new raw garbage is thrown in, the eggs will hatch with the composting organic waste and die before the eggs hatch and emerge. To do.

  Further, in addition to the above-described effects, the inner surface of the water-permeable cylindrical body is tapered from bottom to top and spreads downward and outward, so that the degree to which the solid is pressed against the inner surface is extremely small. Therefore, since the degree of adhesion to the inner surface is extremely small, the organic waste thrown in from the top and deposited in the inside is composted, reduced in volume, and smoothly falls without causing shelf hanging.

  According to the first and second aspects of the present invention, the water-permeable cylindrical body has no special skills or tools by combining and stacking a plurality of concrete blocks that are inexpensive and easily held by hand. In addition, it can be easily formed and is extremely economical.

  According to the second aspect of the present invention, the plurality of square frames F constituting the water-permeable cylindrical body 50 are fixed by the four corner ridges 27 so as not to easily move and lose shape. Therefore, it is not necessary to fasten each square frame F with a wire band or the like for preventing the deformation of the shape.

According to the inventions of claims 1 and 2, if a simple formwork is prepared in the main part, which is a commercially available mass-produced and inexpensive concrete block of a standard length, raw concrete is injected into it. A desired length of concrete block is easily and inexpensively manufactured simply by joining the desired length sub-parts together. Accordingly, it becomes extremely easy to form square frames having different sizes by combining them, and it is also easy to form a tapered water-permeable cylindrical body by stacking them. In addition, it is preferable that rod-shaped reinforcing bars, such as a nail, are used as a joint reinforcement material of both.

  The first embodiment for carrying out the organic waste composting and volume reducing apparatus of the present invention will be described with reference to FIG. 1. As shown in FIGS. 1A and 1B, 50 is directed from the bottom to the top. A tapered and upright water-permeable cylindrical body in which a plurality of square frames F having different lengths on one side are stacked in seven stages. The square frame F is formed by combining four concrete blocks CB on the same horizontal plane with the surface through which the hollow portion H passes up and down, as shown in FIG. It is a thing. In addition, 100 is a foundation which supports the cylindrical body 50, and a plurality of concrete blocks CB are laid with the side faces up so that the hollow portion H penetrates horizontally.

  As a constituent member of the water-permeable cylindrical body 50, a commercially available concrete block is inexpensive and easily available, and preferably, but a fastening member such as a wire band is used so that the square frame F does not lose its shape. Therefore, a modified concrete block which does not require it, which will be described later, is more preferable. In addition, the integrated product or the block may be an inorganic sintered body such as clay clay unglazed.

  The upper opening 51 of the cylindrical body 50 is covered with a roof 60 having a lid 61 and an inlet 62 for introducing organic waste so that rainwater does not enter. Note that the side surface of the roof 60 is fixed to the cylindrical body 50 by a fastener 63, and a ventilation window 64 through which air can enter and exit the cylindrical body 50 is provided on the side surface. Further, a lower opening 52 for introducing air is provided in the lower portion of the cylindrical body 50. Above the lower opening 52, the solid waste made of the input organic waste or the compost produced by fermentation thereof is supported, and air introduced from the opening passes therethrough, and the organic waste is composted. A lattice 70 made of a plurality of rod-like bodies is provided through which fine particles generated by the above can pass and fall.

  In addition, in order to promote air supply to the organic waste deposited in the central portion of the cylindrical body 50, at least one hollow tube 80 having a large number of small through holes on the side surface is provided in the lattice 70 and the inside thereof. It is supported upright by a horizontal support bar 81 penetrating through it.

  To explain the operation, the water-permeable cylindrical body 50 can be used by an unfamiliar person without any special skills and tools even by an amateur by only stacking a plurality of square frames F, which is a combination of four inexpensive concrete locks CB. And can be easily assembled.

  The upright water-permeable cylindrical body 50 is inserted from the upper part and has not only the lower opening 52 and the ventilation window 64 of the upper roof 60 but also the hollow part H that constitutes the cylindrical body 50. Air that is necessary for the growth of aerobic bacteria is sufficiently supplied through the concrete block CB, which is rich in nature, and it is generated along with fermentation, including excess water contained in the organic waste introduced from above. Since water and carbon dioxide gas are discharged to the outside, organic waste that has become suitable moisture is fermented by aerobic bacteria one after another, and even after being put in, a small amount of dark brown and odorless after several months It is taken out as compost.

  Therefore, the input organic waste containing water does not rot and does not emit the bad odor accompanying it, and is reduced in volume and finely divided into a small amount of compost. Can be easily taken out to the outside through the opening 52, so that it contributes significantly to the recycling of organic waste and environmental conservation despite its simplicity. Normally, treatments such as addition of a fermentation accelerator, forced ventilation, and agitation, which are required for processing garbage, are completely unnecessary.

  In addition, the hollow tube 80 is supplied with the air that has entered from the lower opening 52 to the organic waste through many small through holes of the hollow tube 80, and is generated along with moisture contained in the organic waste and fermentation. In order to discharge moisture and carbon dioxide gas, the internal organic waste will be prevented from decay and composting will be promoted from the inside. In addition, insect venting nets are stretched on the ventilation window 64 to prevent intrusion of cocoons and the like, but even if cocoons and so on enter unexpectedly and lay eggs in organic waste, As the eggs are hatched and emerged, they fall with the organic waste that is being composted and die.

  Furthermore, since the inner surface of the water-permeable cylindrical body 50 is tapered from the bottom to the top and spreads downward and outward, the degree to which the solid matter is pressed against the inner surface is extremely small. Since the degree to which this is done is very small, the organic waste thrown in from the top and deposited inside is composted, reduced in volume, and falls smoothly without causing shelves.

  The concrete block CB, which is a modified version of the concrete block, will be described. As shown in FIG. 2, the concrete block CB is composed of one end of a rectangular parallelepiped main portion 11 (which is mass-produced and can be used as it is), and the same cross section as the main portion 11. And the other end of the sub-portion 15 in which the ridges 17 project in a hook shape perpendicular to the side surface of the rectangular portion 16 having a desired length, and a bar-like reinforcing bar such as a nail By being interposed as the joint reinforcing material J, they are joined together.

  As a result, one end of the side surface in the longitudinal direction is provided with a ridge 17 projecting vertically and in a bowl shape on the side surface, and the combination of the four forms a square shape as shown in FIG. When the frame F is formed, the corner C1 outside the end of the one CB of the adjacent two concrete blocks CB and CB on the side where the protrusion 17 is not provided is the protrusion 17 of the other CB. It is comprised so that it may be fitted by the corner | angular part C2 inside the base of.

  Explaining the operation, the plurality of square frames F constituting the water-permeable cylindrical body 50 are easily moved by the large friction between the surfaces that come into contact with each other, hooked on the four corner protrusions 17, respectively. It is fixed so as not to lose its shape, and it is not necessary to fasten each square frame F with a wire, band, or the like for preventing the loss of shape.

Moreover, if a simple formwork is prepared in the main part 11 which is a commercially available mass-produced and inexpensive standard-length concrete block, then raw concrete is injected into the main part 11 and a sub-part 15 of the desired length. The concrete blocks having a desired length can be easily and inexpensively manufactured by simply joining them together. Therefore, the formation of the square frame F having different sizes by the combination is remarkably facilitated, and the formation of the tapered water-permeable cylindrical body 50 by the stacking thereof is remarkably facilitated.
In this case, it is desirable that a rod-like reinforcing bar such as a nail is used as the joint reinforcing material J of the both 11 and 15.

The best form example for implementing the composting and volume reduction apparatus of the organic waste of this invention is shown, (a) is a front view, (b) is a side view, (c) is a frame used for it, and It is a concrete block top view which comprises it. It is a front view which shows the some concrete block from which the length which comprises the water-permeable cylindrical body of FIG. 1 differs, respectively.
