Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an apparatus that is installed in a store, a general household, or the like and facilitates handling by reducing the capacity of discharged plastic such as plastic bottles and plastic containers discharged.
[0002]
[Prior art]
Waste plastics such as plastic bottles and plastic containers discharged in large quantities from ordinary households are collected for recycling.
[0003]
[Problems to be solved by the invention]
However, in particular, hollow containers such as PET bottles are very bulky, which makes collection and transportation very inconvenient. In addition, collection efficiency can be expected by collecting it at a convenient place for general consumers, such as a convenience store, but if the device itself is complex and large, it is difficult to install the collection device. It also hinders the spread. Therefore, it is necessary to make the recovery device compact.
[0004]
[Means for Solving the Problems]
The present invention provides a container (1), a heating unit (6) for dissolving the waste plastic (10) inside the container (1), and a net-like or fence-like shelf that bisects the inside of the container (1). It constitutes a waste plastic volume reduction device that forms part (2).
[0005]
With such a configuration, when a plastic bottle or the like is put into the container (1), the plastic waste (10) is temporarily held on the shelf (2) and is heated and melted by the heating means (6). The molten waste plastic (11) is dropped from the gap between the shelves and collected in the container (7) below the container (1) and solidified. The waste plastic (11) dissolved by the volume reduction treatment is not bulky, so it is very easy to handle and can be expected to improve the convenience of collection and transportation. In addition, even if an aluminum cap or the like is put in the mouth of a PET bottle or the like, the cap remains on the shelf (2), so that it is convenient for sorting during processing.
[0006]
DETAILED DESCRIPTION OF THE INVENTION
The present invention comprises, in the container (1), a heating means (6) for dissolving the waste plastic (10) product, and a fence-like or grid-like shelf that bisects the inside of the container (1). Waste plastic (10) Construct volume reduction device
[0007]
Embodiment 1
(A) The container (1) is a hollow body having an appropriate capacity, and is formed with a discharge hole (3) for the plastic waste (10) at the top, and an open / close lid (4) for the discharge hole (3). Provide. This is because the inside of the container (1) becomes hot and an odor may be generated, so that an open / close lid (4) is provided to prevent the spread of a strange odor.
[0008]
In addition, a container (7) in which waste plastic (11) that has been dissolved and dripped is stored is stored in the lower part of the container (1), and the container (7) can be taken out from the outside by providing means for taking out the container (7). And In the example shown in the drawing, a drawer-type container (7) is configured to be freely taken out at the lower part of the apparatus.
[0009]
Further, the main body of the container (1) is preferably manufactured from a material having heat insulation properties because the inside becomes high temperature. This is to eliminate the influence on the outside of the container (1) and increase the heating efficiency in the container (1). Further, as described above, odor may be generated in the container (1). Especially when this apparatus is installed indoors, the odor exhaust pipe (14) for odor removal from the container (1) to the outside. It is desirable to provide
[0010]
(B) A shelf (2) that bisects the inside of the container (1) is formed inside the container (1). The shelf (2) has a mesh shape.
[0011]
(C) The heating means (6) is formed inside the container (1). In the illustrated example, a surface heating element that generates heat when energized is provided on the side surface inside the container (1). In the present embodiment, the heating element is attached at a location where the container (1) includes an inner side surface and a shelf (2), and includes a portion where the inner surface is connected to the shelf (2). is doing. That is, in a state where the waste plastic (10) is on the shelf, the waste plastic (10) is formed at a location convenient for heating.
[0012]
The heating element is also provided in the lower part of the container (7). Such a configuration is a configuration for further heating the plastic dripped in the container (7) to achieve a more complete volume reduction.
[0013]
The heating element is not particularly limited as long as it can raise the inside of the container (1) to a temperature at which the waste plastic (10) is dissolved. For example, there is a method of heating by sending warm air.
[0014]
Waste plastic (10) configured as above When the waste plastic (10) such as a PET bottle is placed through the loading hole (3) of the volume reduction device, the waste plastic (10) is temporarily held on the shelf (2). And heated. Accordingly, since the entire surface of the waste plastic (10) can be heated from the top, bottom, left and right, it can be efficiently dissolved. When the waste plastic (10) is dissolved, it is dropped through the shelf (2). Since the dropped plastic plastic (10) is collected in the container (7) below the container (1) and solidified, the subsequent handling becomes extremely easy.
[0015]
Moreover, since the shelf (2) has a mesh shape, even if the cap (12) is attached to the plastic bottle, only the cap (12) is left on the shelf (2). The foreign matter such as the cap (12) can be prevented from being mixed, and the labor of sorting can be saved.
[0016]
Embodiment 2
The container (1) having the same configuration as (a), (b), and (c) in the embodiment 1 is constituted, and the container (1) is divided into the upper part and the lower part by the shelf (2) inside the container. By providing a drop door (5) that further bisects the upper part of the upper part, an upper input part (8) and a lower process part (9) are formed, and the lower face of the drop door (5), that is, the treatment The heating means (6) is formed on the surface on the part (9) side.
[0017]
When the drop door (5) is closed, the drop door (5) blocks the input section (8) and the processing section (9). When the waste plastic (10) is inserted, the drop door (5) opens to the processing unit (9) side, and the waste plastic (10) falls into the processing unit (9). Thereafter, the drop door (5) is closed again, so that even when the opening / closing lid (4) is opened during the heat treatment, accidental accidents or odors can be blocked and deterioration of heating efficiency can be prevented.
[0018]
Since the heating means (6) is formed on the lower surface of the drop door (5), in combination with the heating means (6) on the inner side surface of the container (1), it is possible to speed up the processing of the waste plastic (10). it can. As the heating means (6), a surface heating element is shown as an example, but the heating means is not particularly limited.
[0019]
Further, the volume can be further reduced by heating the plastic waste piece (13) that has fallen into the container (7) without being completely reduced in volume in the container (7). That is, the heating means (6) is formed in the container (7).
[0022]
In addition, by combining the first and second embodiments, it is possible to speed up the processing of the plastic waste (10).
[0023]
【The invention's effect】
According to the present invention, it is possible to reduce the volume of waste plastic such as a plastic bottle, and if it is installed in a store, its collection and transportation becomes very easy. Further, the structure is relatively simple, the size can be easily reduced, and it is easy to spread to a general household and is practical. Furthermore, foreign matters such as a cap can be prevented from being mixed into the waste plastic after melting, and the labor of sorting can be saved.
