Detailed Description of the Invention

[0001]

INDUSTRIAL APPLICABILITY The present invention has a simple structure and can be easily used for wastes having a relatively low water content such as papers and plastics generated in homes, stores, offices, businesses, etc. The present invention mainly relates to a waste treatment device suitable for home use.

[0002]

2. Description of the Related Art It has been a long time since people have been calling for a reduction in the amount of waste, but in order to do so, it is necessary to understand the contents of the waste. For example, looking at the breakdown of household waste, except for recyclable items such as cans, bottles, and newspapers, garbage generated around the kitchen, plastics for packaging foods, and other miscellaneous papers It can be roughly classified into three types of garbage. The volume occupied by food waste is small, and it is said that plastic and paper waste account for 90% or more of the total volume. It is a general method that these treatments are carried out intensively at a treatment facility such as an incineration site or a landfill site by collecting trucks that go to a place for a predetermined time and collecting them. Therefore, in general households, it is necessary to store the garbage until a predetermined date when the collection is performed, and it is necessary to transport it to a predetermined place at the time when the collection is performed. In order to eliminate these inconveniences, some devices and methods have been proposed for treating waste at (near) the place where it is generated. For example, the disposer is a system that atomizes food waste by mechanical force and flows it into the sewage together with water.As other methods, a heating and combustion system using a heater,
There are a refrigeration system and a microwave heat combustion system to prevent odor. However, these are all processing devices for food waste and cannot be used for reducing the weight of plastics and papers.

[0003]

[Problems to be Solved by the Invention] Plastic waste and paper waste are small in weight but large in volume as a whole. This is because food trays, containers, bottles, packaging bags, wrap films, etc. are discharged as plastic waste, and packaging paper, advertising paper, OA equipment paper, and other paper waste is discharged in large amounts, especially at home. This is the main cause of the increase in space. In addition, vinyl chloride and vinylidene chloride containing chlorine are usually mixed in the plastic waste as chemical components, and avoid the generation of chlorine-based gas during combustion. These plastic wastes are non-combustible materials (do not burn). It was often treated as landfill waste and sent to landfill, which also caused an increase in the amount of landfill waste. Further, although paper waste is normally burnt, it requires a large space for storage because it is bulky in volume.

On the other hand, looking at the conventional waste disposal equipment, most of the disposers, incinerators, freezers and the like are waste disposal equipments, and there is no effective means for plastics and papers. However, a practical waste treatment device for them is still in a state that is not yet available on a general-purpose level, and it has been a problem to realize it at an early stage.

The present invention solves the above-mentioned problems and is mainly used for garbage having a relatively low water content in papers and plastics generated in homes, offices, businesses, etc., which has a simple structure and can be easily used. It is an object of the present invention to provide a processing device suitable for home use.

SUMMARY OF THE INVENTION In order to solve the above problems, the present invention provides a waste container having a variable internal volume for storing the waste and a waste container in which the internal volume of the waste container is forcibly changed. The waste treatment device has a configuration including a compression mechanism using air pressure for reducing the volume.

[0007]

The present invention has the above-described structure and mechanism to remove dust having a relatively low water content such as plastic dust and paper dust.
(EN) Provided is an apparatus having a simple structure and capable of easily processing. That is, first, put plastic waste, paper waste, etc. in the waste container. Next, air pressure is used to forcibly operate the dust container with a variable internal volume, reduce the internal volume and compress the dust. The waste stored along with the change in the internal volume of the waste container is easily compressed and the volume is greatly reduced. This compression step may be repeated multiple times. In this way, the volume and volume of waste can be reduced with an extremely simple structure and operation.

EXAMPLES Specific examples will be described in detail below. FIG. 1 is a longitudinal sectional view of essential parts showing a first embodiment of a waste treatment apparatus according to the present invention. Reference numeral 1 denotes a waste container, which has a multi-node shape and is configured to be expandable and contractable by sliding a node portion, and as a result, the internal volume is variable. Dust such as plastic and paper is put inside this. Although the dust container 1 is made of a plastic material here, other than this, an FRP material, a metal material, or the like can be used. Reference numeral 2 is a main body container, and 3 is a door that opens and closes when taking in and out trash. Both of them and the dust container 1 have a structure having a mechanical strength enough to resist the force applied to the portion. Further, the lid 3 has a mechanism (not shown) that can be closed against the internal force formed by the main body container 2. Reference numeral 4 denotes a bag provided outside the multi-nodular waste container 1, which is made of a flexible plastic material, but can also be made of a rubber material. Reference numeral 11 is a pedestal on which the dust container 1 is placed, and 12 is a packing for keeping airtightness inside. Reference numeral 8 is an air pump, 9 is a suction port, and 10 is a projecting port. The airtight space 13 formed by the main body container 2, the bag 4, and the packing 12, and the air pump 8 constitute a compression mechanism utilizing air pressure. Reference numeral 5 is an exhaust pipe, 6 is an exhaust inlet, and 7 is an exhaust outlet.

Next, the operation will be described. Waste such as plastic and paper is put into the waste container 1 and the lid 3 is closed. Next, the air pump 8 is operated. Air is sucked in through the suction port 9 and introduced into the airtight space 13 through the projecting port 10. Then, the bag 4 is compressed from the outside and pressed against the dust container 1, and further pushes up the dust container 1. The force causes the nodes of the waste container 1 to slide and reduce itself. At this time, the dust contained in the dust container 1 is compressed and its volume is reduced. When the dust container 1 is contracted, the air therein is exhausted from the exhaust port 7 through the exhaust pipe 5 to the outside of the device. In this way, a reduction in the amount of waste can be achieved very easily. When the set pressure during pressurization is reduced, a high-pressure fan can be used instead of the air pump. Here, since the set pressure at the time of pressurization is 0.2 kg / cm ² and the lateral cross-sectional area of the waste container is about 300 cm ² , a high total compression force of about 60 kg can be exerted. The set pressure can be further increased, and a compressive force about 20 times the above can be easily generated when an air pump is used, and a higher pressure can be obtained by using an air compressor. Therefore, it is possible to select an appropriate compression force in a wide range according to the purpose etc.However, the above compression force is sufficient when targeting general dust, and from the viewpoint of equipment safety and special The above setting is advantageous also in that a withstand voltage configuration is unnecessary and an inexpensive configuration is possible.
