Description

[Detailed Description of the Invention] This invention relates to a compost generating container that promotes aerobic decomposition of food waste.

Compost is generally a self-sufficient fertilizer made by accumulating and fermenting straw, fallen leaves, wild flowers, etc. It is loaded in a building and reloaded as appropriate, and ammonium sulfate, lime nitrogen, fermentation bacteria, etc. may be added to accelerate ripening. many. Most organic materials can be used as raw materials for compost, so if food waste generated by farmers and households can be composted, it is possible to process food waste and produce fertilizer for gardening at the same time, which is a win-win situation. However, in the case of outdoor composting, it has been impossible to compost food waste in general households due to hygienic problems due to the loss of components and the problem of odor generation due to the start of fermentation.

This invention proposes to create a container that facilitates composting of food waste, and to further improve this container. Therefore, the purpose of this invention is to provide a compost producing container that promotes the fermentation of garbage through aerobic decomposition by installing a perforated plate inside the container.

Next, to explain based on the drawings of this invention, the first
The figure shows a compost generating container 1 according to this invention. The container 1 consists of a relatively large plastic cylinder 2 with both upper and lower end faces open, and the cylinder is generally cylindrical or prismatic in shape with a diameter that gradually decreases toward the top. On the upper end surface of the cylinder 2, a lid 4 with a handle 3 formed in the center is placed so as to be openable and closable. It may be attached to the cylindrical body 2 via a It is preferable to provide diametrically opposed recesses 5, 5 above the outer peripheral surface of the cylinder 2, which recesses are used when transporting the container 1. The lower part 6 of the cylindrical body 2 substantially entirely bulges outward, and its lower end forms a flange part 7 bent further outward. The compost outlet 8 is provided in a substantially rectangular shape in the lower part 6 of the cylindrical body, and the upper side of the outlet is located at the upper step of the lower part 6 of the cylindrical body, and the lower side thereof is located in the flange part 7.
It is preferable to position it above. A lifting lid 9 is removably fitted into the compost outlet 8, and the horizontal cross section of the lid has a radius of curvature approximately equal to that of the cylindrical body 2;
It is held on both side edges of the pull-up lid 9 by the shoulders on both sides of the outlet 8.

Further, a circular porous plate 10 is provided along the inner circumferential surface of the lower part 6 of the cylinder.
However, as shown in FIG. 2, it is preferable to remove the outlet 8 from the porous plate 10. The porous plate 10 has a large number of through holes 1.
1 and/or blind holes are provided so as to be distributed over the entire surface, and are fixed to the back surface of the cylinder body 2 by adhesive or other suitable means.

This compost generating container 1 is placed on the ground, and it is preferable to dig the ground flat by about 3 cm and place the container 1 so that the flange portion 7 is embedded so that the container 1 is stable. container 1
Any organic matter such as kitchen scraps, fallen leaves, wild grass, etc. can be thrown into the container.For example, when the thickness of the introduced organic material reaches about 20 cm, an appropriate amount of fermentation accelerator can be sprinkled. In the container 1, the pores 11 of the porous plate 10 contain air, that is, oxygen, so that even if the input organic matter is loaded in layers, aerobic decomposition proceeds, which is biologically the most energy efficient method. This is an advantageous form of decomposition and therefore eliminates the need for artificial transshipment of organic layers. Further, promoting the fermentation of food waste through aerobic decomposition is preferable in terms of deodorization because it does not generate methane gas, sulfide, etc. as is the case with anaerobic decomposition, and organic matter can be composted more quickly. After spraying the fermentation accelerator, when the thickness of the input organic matter reaches about 20 cm again, the fermentation accelerator can be sprayed again, and this operation can be repeated. After 2 to 3 months have elapsed after the addition of the organic matter, the composting from the bottom of the organic matter layer will be completed, so it is only necessary to open the lifting lid 9 and take out the compost from the outlet 8. Porous plate 10
It is preferable to make it removable so that it can be cleaned or replaced if the holes 11 become clogged with organic matter after long-term use.

FIG. 3 shows a modification of this invention, in which a perforated plate 1 is installed along the inner peripheral surface of the lower part 6 of the cylindrical body 2.
2 is a corrugated plate which is approximately circular as a whole but further has a corrugated longitudinal section.
As a result, a large number of air chambers 13 are formed between the inner peripheral surface of the lower part 6 of the cylinder and the outer surface of the corrugated plate 12, and each air chamber communicates with the inside of the container 1 through the through hole 14. There is. The corrugated plate 12 is fixed to the back side of the compost 2 by adhesive or other suitable means, and the upper part 1 of the plate is fixed as shown in FIG.
5 is preferably partially bent toward the inner peripheral surface of the cylinder. When the corrugated plate 12 is installed, each of the air chambers 13 and the through holes 14 contain air, so that the input organic matter loaded in layers comes into better contact with the air, and aerobic decomposition proceeds more quickly. I will do it.

With the composting container of this invention, large amounts of food waste generated by farmers and households, as well as fallen leaves and wild plants, can be easily composted, which is beneficial in terms of waste disposal and fertilizer production. In the container of this invention, a perforated plate is installed inside the cylinder, so that the aerobic decomposition of the input organic matter progresses rapidly.
This is preferable because there is almost no odor caused by methane gas, sulfides, etc. As a result of such deodorizing treatment, the container of this invention can be placed near the kitchen of a household or in the garden, and has the advantage of not receiving complaints from nearby residents.
