DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a relatively small amount of plastic garbage, such as packaging materials for perishable foods and the like that frequently occur in homes, especially kitchens, and packaging materials and the like generated in small business establishments and stores. The present invention relates to a small and easily usable plastic waste disposal apparatus .

[0002]

2. Description of the Related Art Most household waste is generated from around kitchens. Looking at the breakdown, the volume is about 8
It is said that plastic is used for packaging such as fresh food, and about half of the weight is food waste such as cooking waste and leftover food. It is a general method that these treatments are performed by a collection vehicle going to a place for a predetermined time and collecting them, and intensively performed in a treatment facility such as an incineration plant or a landfill. Therefore, in general households, it is necessary to keep the garbage until a predetermined date when the collection is performed, and it is necessary to transport the garbage to a predetermined place when the collection is performed.

[0003] In order to eliminate such inconveniences, there have been proposed some devices and methods for treating refuse at (near) a place where the refuse is generated. A typical example is a so-called disposer. This is a method in which the garbage is made finer by mechanical force and flows into the sewage together with water.
It is only for garbage and cannot be applied to the treatment of plastic waste. Other methods include a heating combustion method using a heater or the like, a refrigeration method for eliminating odor, a microwave heating combustion method, and the like. However, these are all garbage processing apparatuses, and a small-sized plastic garbage processing apparatus suitable for homes, small business establishments, and the like has not yet been put to practical use.

[0004]

[0006] To reiterate, plastic waste occupies a small weight in the whole waste but has a large volume. This is because plastic food trays, containers, bottles, packaging bags, wrap films, and the like are discharged in large amounts as garbage, and this is a main cause of an increase in garbage storage space at home. In addition, chlorine-based plastics are usually mixed in the garbage, and these plastic garbage, which avoids the generation of chlorine-based gas during combustion, are treated as noncombustibles (garbage that must not be burned) and used for landfill. It is often turned around, causing an increase in the amount of waste at the final landfill site.

On the other hand, regarding conventional waste treatment apparatuses, most disposers, incinerators, refrigeration systems, etc. are garbage disposers, and there is no effective means for plastics. Especially, plastic refuse treatment equipment for domestic use is still in a state of general use, and it has been an issue to realize it at an early stage.

[0006] One of the realizing methods is to soften and compress plastic waste to reduce its volume. However, when plastics are heated, a characteristic odor is generated. In addition, garbage and the like adhered to the plastic also generate a bad smell when heated. Therefore, this type of refuse treatment apparatus requires a means for removing an odor generated during heating. This is a new challenge.

SUMMARY OF THE INVENTION The present invention solves this problem and reduces the weight (volume reduction) of plastic garbage generated in kitchens and the like for packaging of perishable foods by a simple configuration and simple operation.
It is an object of the present invention to provide a refuse treatment apparatus which eliminates a bad smell generated during operation of a treatment apparatus mainly suitable for home use.

[0013]

According to the present invention, there is provided an apparatus for easily and sanitarily treating plastic waste by the above-described structure and mechanism. That is, for example, the plastic waste put in the waste container is heated by a heater to a predetermined temperature (100 to 1).
About 50 ° C). When a certain kind of plastic refuse such as a foamed material reaches a sufficient temperature, its volume can be greatly reduced by an operation of heating alone. As described above, the plastic loses its elasticity due to a rise in temperature due to heating, and cannot maintain its original shape. As a result, the apparent volume is greatly reduced. However, the material is rarely specified as plastic refuse, and it is common that various materials are mixed to become refuse. At that time, heating at a certain temperature often still has sufficient elasticity depending on the material. In such a case, it is necessary to achieve a consolidation by adding a compression operation after heating. A variable-volume waste container is forcibly operated to reduce its internal volume and compress plastic waste. At this point, since the plastic waste is softened or partially melted in accordance with the temperature rise due to the heating, the plastic waste is easily compressed with a change in the internal volume of the waste container, and the volume is greatly reduced. This compression step may be repeated several times during heating.

In this way, the amount of waste and the volume of waste can be reduced, but during this heating, in most cases, an odorous gas is generated from the heated processing space. Since the pressure in the processing space having a certain volume increases due to heating, the generated odorous gas flows out of the processing space to the outside through the gaps between the devices. The outflow gas containing the malodorous component is guided to the deodorizer by using a blower or draft force together with the surrounding air, and is discharged to the outside of the apparatus after passing through the deodorizer, thereby achieving deodorization. Alternatively, an outflow channel is formed in advance from the processing space to the outside, a deodorizer is installed on the outflow channel, and similarly, deodorization is achieved by discharging the gas to the outside of the apparatus through the deodorizer. At this time, a blower is installed on the flow path together with the deodorizer, and the malodorous gas is guided to the deodorizer using the pressure of the blower. In addition, the hot air generator for heating the plastic waste is composed of a heating unit and a blower, and the odor gas generated during heating flows out of the processing space where hot air circulates to the outside at the position immediately after the blower. An outflow passage is provided to guide the odorous gas to the deodorizer using the pressure of the blower.

[0015]

Embodiments of the present invention will be described below with reference to the drawings.

[0016] Figure 1 is a first embodiment of a deodorizing device according to the invention
It is a principal part longitudinal cross-sectional view which shows an example . Reference numeral 1 denotes a refuse container in which plastic refuse is put in its internal space 2. Reference numeral 3 denotes a container body. Reference numeral 4 denotes a blower, and 5 denotes a heater, both of which constitute a hot air generator. The hot air generated in the same portion is guided from the hot air outlet 7 to the inner space 2 to heat the plastic waste. Thereafter, the hot air is returned from the hot air suction port 6 to the hot air generating section, and circulates in the processing space. In this way, the plastic waste placed in the waste container 1 is heated. Reference numeral 8 denotes a lid, in which the blower 4, the heater 5, and the like are housed. The lid 8 is engaged with the main body 3 by a hinge 15 and can be opened and closed with the same portion as a fulcrum, and is opened and closed when dust is taken in and out. 13 is an inner packing and 14 is an outer packing.

Further, a deodorizing section composed of a blower 9 and activated carbon 10 is formed inside the lid 8, and sucks odor components leaking out of the processing space 2 and air in the vicinity during the heat treatment of the plastic waste. It has a mechanism to adsorb and deodorize odor components. Air is sucked from the air inlet 11 and the air outlet 1
Exhausted from 2. Here, the deodorizing section is constituted by the honeycomb-shaped activated carbon 10 and the blower 9 and has a mechanism utilizing an adsorption reaction. However, a method utilizing an oxidative decomposition reaction with a catalyst (and a heater) or an ozone (and a catalyst) is employed. Alternatively, a mechanism utilizing a similar oxidation reaction to deodorize the air may be used, and a mechanism for collecting the odor using a blower may be used. Also,
The adsorbent is not limited to the activated carbon shown in the present embodiment, and various types such as those using inorganic materials such as silica gel can be used, and can be selected from a wide range according to the purpose and the like. The shape of the activated carbon can be appropriately selected from a granular shape, a fibrous shape, a corrugated shape obtained by molding them, and the like. Generally, plastics lose elasticity by heating, and soften or shrink.

The plastic waste treatment apparatus having the above structure is suitable for treating a foamed material made of a material such as polystyrene or polyethylene. In particular, expanded polystyrene generates a peculiar odor when heated, so that a deodorizing operation is effective. Further, other organic components, sewage, and the like are usually attached to the plastic waste, and when heated, they also cause odor. However, the deodorizing mechanism described in this embodiment is sufficiently effective for such odors. The heating temperature is 1
A temperature of about 00 to 150 ° C. is appropriate and may be determined according to the physical properties of the target plastic waste. In that case, a method of attaching a temperature detector (not shown) near the hot air outlet 7 to control the outlet temperature is preferable.

FIG. 2 is a longitudinal sectional view of a main part of an apparatus according to a second embodiment of the present invention. Portions that are the same as those in the first embodiment shown in FIG. 1 are denoted by the same reference numerals, and description thereof is omitted. FIG.
The different part is the configuration of the deodorizing section and the method of collecting the odor component in the deodorizing section. In the present embodiment, the deodorizing section utilizing the activated carbon adsorption reaction is located above the lid 8. In the present embodiment, the collection of the odor component in the activated carbon 16 which is the deodorizing section is performed by using the updraft (draft) force of the air. Therefore, a lower body air opening 17 is provided at the lower part of the main body 3, an upper body upper opening 18 is provided at the upper part of the main body 3, a lower body lower opening 19 is provided at the lower part of the lid 8, and an activated carbon 16 at the upper part of the lid is provided at the upper surface. Exhaust port 20
Is provided.

When the plastic waste placed in the waste container 1 is heated, the waste container 1 is naturally heated and its temperature rises.
At this time, heat is radiated from the outer wall of the refuse container 1 to air near the outside thereof, and the air temperature rises. As a result, the air density decreases and an updraft occurs. Therefore, it is introduced from the lower body air opening 17 and the upper body opening 1
8. An air flow exhausted from the exhaust port 10 is formed by sequentially passing through the lower cover opening 19 and passing through the activated carbon 16 on the upper cover. The odor component leaking from the processing space gets on the airflow and passes through the activated carbon 16, so that it is deodorized in the same part and discharged to the outside. In this way, deodorization is achieved. The setting of the heating temperature, the selection of the deodorizing material, the configuration of the deodorizing section, and the like have the same degrees of freedom as in the first embodiment, and therefore can be selected according to the conditions of the processing target and the like.

FIG. 3 is a longitudinal sectional view of a main part of an apparatus according to a third embodiment of the present invention. Reference numeral 21 denotes a refuse container in which plastic refuse is put in an inner space 22 thereof. 23 is a main body. Reference numeral 24 denotes a blower, and reference numeral 25 denotes a heater, both of which constitute a hot air generator. The hot air is introduced into the inner space from the hot air outlet 27 to heat the plastic waste, and the hot air suction port 6
From the hot air generating section and circulates in the processing space. At this time, the processing space indicates a space in which hot air circulates. In this way, the plastic waste placed in the waste container 21 is heated. Reference numeral 28 denotes a lid, in which a blower 24, a heater 25 and the like are housed. The lid 28 is engaged with the main body 33 by a hinge 35 and can be opened and closed with the same portion as a fulcrum, and is opened and closed when dust is taken in and out.

Reference numeral 33 denotes an inner packing, and reference numeral 34 denotes an outer packing. Further, a blower 29 and activated carbon 30
A deodorizing unit is configured to absorb the odor component leaking from the processing space and the nearby air during the heat treatment of the plastic garbage, and adsorb and deodorize the odor component.
Air is sucked in from the air inlet 31 and discharged from the air outlet 32. Here, the deodorizing section is constituted by the honeycomb-shaped activated carbon 30 and the blower 29 and has a mechanism utilizing an adsorption reaction. However, a method utilizing an oxidative decomposition reaction with a catalyst (and a heater) or an ozone (and a catalyst) is employed. 1 and 2, a mechanism utilizing a similar oxidation reaction to deodorize the air and collecting the odor with a blower may be used.
This is the same as in each embodiment shown in FIG. Other types of adsorbents, or other forms of adsorbents, are also available.

In this embodiment, a plastic dust compression mechanism is added. Plastics lose elasticity by heating and soften. At this time, volume reduction can be surely achieved by applying a compressive force. Here, the compressive force is generated using air pressure. Reference numeral 38 denotes an air pump for pumping air to generate a compressive force, 39 denotes a compressed air intake, 42 denotes an on-off valve, 43 denotes a valve exhaust port, and 44 denotes a lower exhaust port. 36 is a garbage container 21
A bottom plate 37, which can move up and down inside, is a bag and is fixed to the lower part of the trash container 21 with a fixing tool 41. 40 is an air supply port.

The plastic waste put in the waste container 21 is sufficiently heated by hot air, softened and then compressed. At the time of compression, the air pump 38 is operated. When the on-off valve 42 is in a closed state, the air introduced from the compressed air intake 39 is fed through the air supply port 40 into the bag 37 under pressure. The bag 37 gradually expands in volume and starts to bulge upward. This force acts as a compressive force and acts on the plastic waste placed in the waste container 21 to reduce the volume of the waste. In this way, the volume reduction process can be achieved more reliably than when only heating with hot air. In this case, the bag body 37 needs to have flexibility and airtightness, and a material such as a plastic sheet having relatively good heat resistance, rubber, or a sheet in which rubber is bonded to a fibrous woven fabric is used. Alternatively, a plastic material, a rubber material, or the like molded into a bellows shape instead of a bag shape can be used.

In this embodiment, the air pump 38 is used as the air pump for compression. However, a high-pressure generating fan may be used. The property is not so strict, and a material such as a woven fabric can be used. After compression, it is desirable to keep the compressed waste in a compressed state until it is cooled to some extent. By doing so, the compression volume reduction processing becomes more reliable. The exhaust opens the on-off valve 42, and the compressed air in the bag 37 is supplied to the air supply port 40 and the on-off valve 42.
And is exhausted from the valve exhaust port 43. Thereafter, the air is exhausted from the lower exhaust port 44 to the outside of the machine. The lower exhaust port 44 is not always necessary because the main body 23 itself is generally not so airtight.

While the on-off valve 42 is open, the bag 37 is slowly shrunk by the weight of the plastic waste in the waste container 21 and the bottom plate 36, and the compressed waste is discharged from the waste container 21.
Move to the bottom of. Therefore, it is also possible to use such a method that the plastic waste is continuously supplied after the treatment is completed and the treatment is performed again when the waste is full, and the compressed and reduced plastic waste is taken out after a plurality of continuous treatments. The greater the pressure during compression, the greater the compression effect and the more effective,
Since the strength of the device itself is required, it is determined in consideration of those conditions. Usually 0.05 ~
It is sufficient to decide between about 0.5 kg / cm ² .

In this embodiment, odorous gas is generated from the processing space to the outside at the time of heating when the gas volume in the processing space expands and at the time of compression when the internal temperature is still high after the heating. . However, in the same manner as in the first embodiment, the odorous substances are guided by the blower 29 together with air to the activated carbon 30 in the deodorizing section, where they are adsorbed and deodorized.

FIG. 4 is a longitudinal sectional view of a main part of an apparatus according to a fourth embodiment of the present invention. Portions that overlap with the third embodiment shown in FIG. 3 are denoted by the same reference numerals, and description thereof is omitted. FIG.
The different part is the configuration of the deodorizing section and the method of collecting the odor component in the deodorizing section. In the present embodiment, the deodorizing section utilizing the oxidative decomposition reaction of the catalyst is located inside the lid 28.
In this embodiment, the odor components are collected in the deodorizing section by sucking the air directly from the opening 46 opened in the processing space 22 by the blower 44, passing the catalyst 45, and exhausting the exhaust gas through the exhaust port 47. 48
Is a catalyst heater for heating and activating the catalyst 45. Here, a seam heater in which the surface similar to the heater 25 is insulated and coated is used.

In this embodiment, since the odor component is directly collected from the processing space 22 to be collected and deodorized, the deodorization is more reliably achieved. As the oxidation catalyst for deodorization, a honeycomb-shaped ceramic carrier made of a component such as lime aluminate is surface-treated with an alumina-based material, and a noble metal-based metal catalyst is dispersed and fixed thereon, and is used in this embodiment. However, the present invention is not limited to this, and activated carbon carriers, other ceramic carriers, and the like can be used.

FIG. 5 is a longitudinal sectional view of a main part of an apparatus according to a fifth embodiment of the present invention. 55 is a blower, 56 is a heater, and both constitute a hot air generator. Reference numeral 57 denotes a temperature detector for controlling the temperature of the hot air. However, it is unnecessary when the heater 56 is of a self-temperature control type. 71 is a hot-air outlet composed of a large number of through holes,
61 is a suction port. These are integrated into the exterior body 54
It is fixed on the upper part of. Reference numeral 53 denotes an outer cylindrical container which is opened upward and has a packing material 59 provided thereon. 6
Reference numeral 2 denotes a bag made of a heat-resistant material, which is made of a plastic sheet material here.

Reference numeral 58 denotes a frame body, which is pushed into the inside of the bag 62, clamps the bag with the packing material 59, and is fixed to the upper portion of the outer cylindrical container 53. The frame body 58 has a U-shaped cross-section, a recessed portion facing the suction port 61, and an air vent 60 at the bottom.
Is provided. The garbage container 51 is suspended from the inner rising portion of the frame 58. The garbage container 51 includes a plurality of cylindrical bodies 51a, 51b, 51c having different diameters and a bottom plate 51d having a vent hole 51e. Make up. Also, the height of the side wall of the bottom plate 51d is adjusted to the cylindrical bodies 51a to 51c.
Is smaller than the side wall height. In this way, it is configured in a multi-node shape so as to be expandable and contractible, and as a result, the internal volume is variable. Plastic waste is put into the inner space 52. Further, the refuse container 51 is made of a metal material, but a heat-resistant plastic material, an FRP material, or the like can also be used.

Reference numeral 63 denotes an air pump used as an air pressure feeding means. The air pump sucks outside air from a suction port 64 and projects air from a protrusion port 65 into an air chamber 72 formed by the outer cylinder 53 and the bag 62. , Pressurized garbage container 5 from outside bag 62
Compress 1 upward. The bag 62 is a constituent material of the air chamber 72 as described above, and also plays a role of receiving moisture, dirt, and the like adhering to the plastic garbage put in the garbage container 51. The frame 58 is configured to be detached and easily replaced when it becomes dirty or when a part of the air chamber 72 cannot be maintained airtight due to damage. The air pump 63 may be configured to be attached to the exterior 54 and communicate with the air chamber 72 by an elastic hose. When the set pressure during pressurization is reduced, a high-pressure fan can be used instead.

As described above, the outer cylindrical container 53 and the packing material 5
9, bag 62, frame 58, trash container 51, air pump 63
Constitute a compression unit, and are fixed on the vertical movement mechanism 66 as a whole. By operating the vertical movement mechanism 66, the hot air generating unit and the compression unit can be freely separated from each other, and when the hot air generating unit and the compression unit are joined, the hot air from the hot air generating unit is connected to the inside of the dust container 51 and the dust container 51. The space 73 formed between the bag 62 and the bag 62 is circulated as a passage. The compression unit including the vertical movement mechanism 66 includes a wheel 67.
And can be pulled out in the left direction in the figure, and is used when throwing refuse.

Incidentally, reference numeral 68 denotes a honeycomb-shaped catalyst body, which is provided with an air supply port 69 opened toward the hot air outlet 71 side,
The exhaust port 70 forms a deodorizing section.

At the time of processing, first, the compression unit is pulled out and plastic waste is put into the waste container 51. Thereafter, the unit is pushed into the exterior main body 54, and the vertical movement mechanism 67 is operated to join the hot air generation unit. Next, the heater 56 and the blower 55 are operated. The generated hot air is blown out from a hot air outlet 71 and supplied to the inside of the garbage container 51 to heat the injected plastic garbage.
Is discharged outside. The discharged air passes through the space 73 and the air inlet 60 of the frame, is sucked into the blower 55 from the inlet 61 again, becomes hot air, and circulates inside and outside the garbage container 51. The plastic waste put into the waste container 51 in this way is heated and its temperature rises. The heating temperature of the plastic refuse is controlled while detecting the temperature of a temperature detector 57 provided near the hot air outlet 71. The compression operation is started when the temperature of the plastic waste rises.

This embodiment, like the other embodiments, utilizes air pressure for the compression operation. When air pressure is used, a large compression force can be obtained with a small pressure, and this is an advantageous method from the viewpoint of safety and the like. First, when the air pump 63 is started, outside air flows from the suction port 64 through the protruding port 65, and
2 and pressurized. The air pressure causes the bag 62 to start shrinking, pushing up the bottom of the refuse container 51, and the refuse container 51 is compressed in the vertical direction to reduce its internal volume. At the same time, the plastic waste put in the waste container 51 is compressed. This compression step may be repeated multiple times during the heating. The cooling during the compression holding may be natural air cooling.
5 or a dedicated cooling fan (not shown) reduces the processing time. The plastic lump that has become a small lump is pulled out of the compression unit, taken out of the litter container 51 and discarded.

By the way, the odor generated during heating or compression is deodorized in the deodorizing section and exhausted, so that the air supply port 69 of the deodorizing section is located immediately after the blowing section. That position is where the static pressure is highest in the processing space. A method may be employed in which the pressure is used to exhaust the gas through the catalyst 68 from within the processing space. Therefore, when the air supply port 69 is opened at this position, there is an effect that a blower for suction becomes unnecessary. In this embodiment, since a catalyst having an oxidizing activity at a relatively low temperature prepared by dispersing a noble metal component in an activated carbon carrier is used, a heater for activating the catalyst is not required.

The above-described first to fifth embodiments can be individually operated, and at the same time, the respective elements can be replaced or combined to form a new embodiment.
