Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a container for treating organic waste, and more particularly to an organic waste treatment suitable for treating organic waste by feeding insect larvae having the property of escaping at the end of life. For containers.

[0002]

2. Description of the Related Art In recent years, livestock dung (cow dung, poultry dung, etc.), which is a typical organic waste, is generated in large quantities with the expansion of livestock production, and its disposal method has become a problem. In particular, in recent years, environmental standards have become strict, and it is not allowed to easily dump unsanitary animal dung that emits offensive odor.

In order to solve the problem of treating animal dung, it has been considered to use an insect biotreatment method in which animal dung is fed to insect larvae to make the harmless or low harmful. This is because animal manure treated with insects can be used as a useful organic fertilizer, and larvae and pupae of insects grown on animal manure can be used as industrial raw materials. If what is obtained by the insect biotreatment can be reused as an organic fertilizer or industrial raw material, the treatment cost of the insect biotreatment can be reduced, and the insect biotreatment is expected to be a practical treatment measure against the animal dung problem.

[0004]

However, in the case of the conventional insect biotreatment, there is a problem that it takes time to separate the treated animal dung and insect larvae. At the time of completion of the insect biotreatment, animal dung and insect larvae remain mixed in the same container, so that an operation of separating animal dung and insect larvae is required. However, the work of separating a large amount of small insect larvae from a large amount of animal dung requires not only a great deal of labor but also a very poor working environment. Unless insect larvae and animal droppings are separated, there is a risk of another problem that unnatural mass outbreaks of insects may occur when used as organic fertilizer.In addition, larvae and pupae of insects are used as industrial raw materials And the processing cost cannot be reduced.

Accordingly, an object of the present invention is to provide an organic waste treatment container capable of separating insect larvae from organic waste that has been treated with insect biomass without any hassle. An object of the present invention is to provide a container for treating organic waste which can separate and collect insect larvae from the treated organic waste without any trouble.

[0006]

The above object is achieved by the invention described in each claim. That is, the characteristic configuration of the container for treating organic waste according to the present invention is to store the organic waste to be treated by insect biotreatment, which is treated by feeding on insect larvae having the property of escaping at the end of life. A possible top-open pallet-shaped container, wherein at least a part of the container side wall has an inclination angle inclined in a direction of falling outward.

[0007] With this configuration, the organic waste to be treated with insects is placed on the bottom of the organic waste during treatment, and is fed to insect larvae, thereby rendering the organic waste harmless or less harmful. On the other hand, insect larvae that reached the end of life after eating organic waste naturally crawled out from the side wall of the container that is inclined to fall outward according to the nature of escape at the end of life, resulting in insect biotechnology Since the insect larvae have already naturally separated from the organic waste at the end of the treatment, the separation of the organic waste and the insect larvae that have undergone insect biotreatment requires little effort. In other words, the present inventor tilts the container side wall in the direction of falling outward and sets it to a predetermined ascending slope, and the insect larva that has finished the feeding period crawls out of the container, and if there is a slope in the front, this slope is They found the use of the property of climbing a plane, and completed the present invention.

In the container for treating organic waste of the present invention,
2. The container according to claim 1, wherein the side wall has an inclination angle of 10 to 45 degrees.
For organic waste disposal.

With this configuration, the side wall of the container is inclined in a direction of falling outward at an angle in the range of 10 to 45 °, so that insect larvae can be extremely easily crawled out, and the organic material treated with insect bio is completed. Separation of waste and insect larvae proceeds rapidly. In this case, if the inclination angle is lower than 10 °, the insect larvae that have completed the feeding period do not always climb the side wall, and even the insect larvae before reaching the end of life may be out of the container. Not preferred. Conversely, if the angle of inclination is higher than 45 °, the insect larva that has reached the end of life, when climbing the side wall, tries to crawl only by peristaltic movement, so the speed of crawling out of the container will be slow, and it will be out of the container. It is not preferable because it may be difficult.

It is preferable that the inclination of the container side wall is formed over the entire circumference of the container side wall.

With this configuration, the insect larvae can easily crawl from anywhere on the side wall of the container.
The separation of the organic waste and the insect larvae that have undergone the insect biotreatment proceeds quickly and is convenient.

Further, it is preferable that the insect larvae having the property of escaping at the end of life are housefly larvae, and the organic waste to be subjected to insect biotreatment is animal dung.

With this configuration, the housefly maggot (larva) eats organic waste to make it harmless or less harmful, while the maggot that has reached the end of its final age (ripe age) falls outward. It easily crawls out of the container side wall that is inclined at an angle by itself, so that maggots can be separated from the organic waste that has been treated with insects with little effort. House flies have strong fertility and repeat outbreaks throughout the year in short cycles, and maggots have a strong appetite, so the insect biotreatment itself progresses rapidly and the property of fleeing at the end of life is remarkable, Separation of the organic waste from the housefly larva also proceeds efficiently.

Further, the characteristic structure of the container for treating organic waste according to the present invention is that the container for treating organic waste according to any one of claims 1 to 4 is an inner container, and is separated from the periphery of the inner container. A composite container comprising a pallet-shaped outer container having a size that can be accommodated and stored in an upper surface opening type pallet, and combining the inner container with the outer container, wherein a wall structure for preventing the insect larvae from crawling out on a side wall of the outer container. Is formed over the entire circumference.

According to this structure, in the inner container according to any one of claims 1 to 4, wherein the outer container is provided with a margin at the periphery thereof, the insect biotreatment proceeds, and at the end of life. Insect larvae that have reached and crawled from the inner container to the outer container, but the outer container has a wall structure around the entire wall that prevents the insect larvae from crawling. By staying inside, the insect larvae are naturally collected in the outer container, and as a result, the insect larvae can be separated and collected from the organic waste that has been subjected to the insect biotreatment with little effort. Therefore, the larva becomes a pupa in the outer container, and useful substances such as chitosan and protein can be collected from the pupa or its shell, or can be used for fishing bait or the like.

Further, the wall structure for preventing the insect larva from crawling out has a side wall rising substantially vertically from a bottom portion, and a return portion which falls down inward is formed around the entire inner surface of the side wall. Preferably.

With this configuration, the insect larvae crawling out of the inner container are further reduced by the side wall that rises vertically and the inwardly-facing return formed over the entire inner surface of the side wall. Since it is possible to reliably prevent the larvae from escaping and escaping, the handling becomes easy, and the insect larvae and pupae can be reliably recovered.
