DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is used in an apparatus for easily processing garbage generated in homes, restaurants, shops and the like.

[0002]

2. Description of the Related Art Conventional waste treatment apparatuses include a mechanical treatment apparatus called a disposer and an incinerator using gas, liquid fuel or electric heating. The former uses a rotary blade to grind kitchen waste and treats it by flowing it into sewage. The latter burns fuel using a burner and incinerates garbage using the heat. Disposers emit large amounts of solids into wastewater to mechanically dispose of kitchen waste. Therefore, clogging of the sewer system occurs, which is a major social problem.

[0003] Further, an apparatus for compressing refuse in a bag has been proposed. The volume of the refuse becomes extremely small because the refuse is contracted using a motor and a gear.

[0004]

SUMMARY OF THE INVENTION The present invention relates to an apparatus for reducing the volume by placing refuse in a container and applying pressure. In the conventional method, since the dust is shrunk using a motor, the mechanism is complicated and the compression force is insufficient.
For this reason, the device is large in size for the storage capacity of the refuse. In addition, it was difficult to clean the device when it became dirty.

[0005]

Means of the present invention for solving the above problems are as follows. A bottomed cylindrical container that is inserted into and taken out of the main body, an air pump provided in the main body, a telescopic air tube that connects the air pump and the cylindrical container, and provided in the cylindrical container. Allows internal volume in the vertical direction
With a storage container for garbage to be changed, after pulling out the cylindrical container with the sliding means and inserting garbage,
The cylindrical container is pushed into the main body, and the upper part of the storage container is pressed against the ceiling of the main body by the air pump to compress dust in the storage container.

For heat-softening refuse such as plastic, a main body having a hot air generating means at an upper portion, a bottomed cylindrical container to be taken in and out of the main body, and air provided in the main body are provided. A pump, a telescopic air tube connecting the air pump and the cylindrical container, and a trash storage container provided in the cylindrical container and having a variable internal volume in a vertical direction.
And a lifting mechanism for the cylindrical container,
While pulling out the cylindrical container and putting garbage, at the time of processing, the cylindrical container is pushed into the main body and lifted, the opening of the cylindrical container is brought into close contact with the hot air generating means, and the garbage is heated to a predetermined temperature. At the same time, the upper part of the storage container is pressed against the ceiling of the main body by the air pump to compress dust in the storage container.

[0007]

The storage container is completely separated from the main body and is connected only by an air pipe. Since the storage container can be easily put in and out of the front and back, it is convenient to put in and out garbage. Also. The body strength against air pressure is strong. Further, since there is no mechanical part by air pressure, the effective volume is large, and the compressive force becomes strong in proportion to the size of the container.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A first embodiment of the present invention will be described below with reference to the accompanying drawings. In FIG. 1, reference numeral 1 denotes a bag made of a heat-resistant plastic such as PBT, which is placed in a bottomed cylindrical container 2 and whose opening is held at the upper part of the cylindrical container 2.

An air pump 4 supplies air to a pressurizing chamber 3 between a cylindrical container 2 and a bag 1 through an air pipe 5.
Inside the cylindrical container 2 is provided a telescopic storage container 6 which is vertically expandable and contractible.

The operation of the above structure will be described. Garbage such as paper, empty bottles, empty cans, etc. is put into the storage container 6. The storage container 6 is returned to the main body 7. After such a state, the air pump 4 is operated to send air to the pressurized space 3 between the cylindrical container 2 and the bag 1. The differential pressure between the inside and outside of the bag 1 is 0.05 to 0.5 kg / cm ²
In this case, the bag 1 is compressed by air pressure and becomes the state shown in FIG.

Dirt adheres most to the inner surface of the bag 1, and if the inexpensive bag 1 is replaced, no dirt remains on the apparatus. Storage container 6
If the compressed waste is put into the dirty bag 1 and discarded, the bag 1 is not wasted. The odor and oil also adhere to the outer wall of the storage container 6, but since the storage container 6 is detachable, dirt can be removed by washing with water.

A rotating part 12 having a slide base 9 at the lower part of the cylindrical container and provided at the front and having wheels below,
Rotating part 1 fixed to bottom plate 13 of main body 7 and having wheels above
4 can slide back and forth while the cylindrical container 2 is placed.

Hereinafter, a second embodiment of the present invention will be described with reference to the accompanying drawings. In FIG. 3, the bag 1 is placed in a cylindrical container 2 having a bottom and an opening is held at an upper portion of the cylindrical container 2. A structure in which pressurized air is sent from the air pump 4 to the pressurized chamber 3 via the air pipe 5. Inside the cylindrical container 2 is provided a telescopic storage container 6 which is vertically expandable and contractible.

FIG. 4 shows the lower part of the cylindrical container 2. Two pins 8 of the cylindrical container 2 are fitted to three tapers 10 provided on the upper part of the slide base 9. By rotating the lever (also used as a pin) 11, the cylindrical container 2 is raised.
The slide base 9 is a rotating part 12 having wheels on the lower front side and downward.
And the rotating part 14 having wheels in the upward direction fixed to the bottom plate 13 of the main body 7 can slide back and forth while the cylindrical container 2 is placed thereon. FIG. 5 shows a state in which the cylindrical container 2 is pulled out forward.

The refuse is put into the storage container 6 from above.
The cylindrical container 2 containing the refuse is pushed into the main body 7 and further lifted, so that the opening 15 is in close contact with the hot air generating means of the main body (FIG. 3 is in a state of close contact). The hot air generating means is provided with a discharge hole 16 at the center bottom, a suction hole 17 around the discharge hole, and a circulating blower 18 and a heater 19 between the two.
And a temperature detector 2 near the discharge hole 16.
0, a catalyst 21 is provided. The air hole 22 and the suction hole 17 between the storage container 6 and the bag 1 are in communication with each other through a packing 23 having a hole when the cylindrical container 2 is inserted into the main body 7.

The operation of the above structure will be described. Heater 19
And the blower 18 is operated, and the air for circulation passes through the lower air hole 24 while heating the refuse in the storage container 6 from the discharge hole 16, the space between the bag 1 and the storage container 6, and the air hole 2.
2, suction hole 17, blower 18, heater 19, catalyst 21,
Circulates through the temperature detector 20. The air hole 24 is provided on the bottom or the side wall of the bottom.

200 ° C. with chloride plastic
If the temperature exceeds, a very large amount of chloride is decomposed. Therefore, the temperature of the discharge hole 16 of the heater 19 is from
The temperature is controlled to be less than ℃. At a temperature in this range, the amount of decomposition of the plastic is small. Although the refuse is heated from the upper part, the amount of air circulated is large enough to circulate the heat and the lower part is also heated rapidly.

In addition, most dirt adheres to the inner surface of the bag 1, and if the inexpensive bag is replaced, no dirt remains in the apparatus. Also,
If the refuse heated in the storage container 6 is put into the dirty bag 1 and discarded, the bag is not wasted at all. The odor and oil also adhere to the outer wall of the storage container 6 similarly.
Can be removed so that dirt can be removed by washing with water.

The refuse is heated by the convection of the hot air and becomes soft,
After such a state, the air pump 4 is operated to send air to the pressurized space 3 between the cylindrical container 2 and the bag 1. Assuming that the differential pressure between the inside and outside of the bag 1 is 0.05 to 0.5 kg / cm ² , the bag 1 is compressed by air pressure and becomes the same state as shown in FIG. The storage container 6 compresses and plastically deforms a hard plastic material which is heated to a glass transition temperature or higher and softened. Although this pressurization is not expected to shrink food-based refuse, the bulk of the plastic refuse can be reduced to about one-tenth or less by deformation.

The hot air that is heating the refuse and the air inside the bag 1 that is pushed out when the bag is compressed are pushed out of the apparatus through the catalyst 21. The catalyst 21 is heated at about 500 ° C.
Is maintained at the activation temperature, and the odor generated by the garbage in the exhaust gas is oxidized by the catalyst 21 to become odorless. After the compression process is completed, the pressure chamber 3 is depressurized from the inside of the bag 1 by reversing the operation of the air pump 4 or by using the blowing pressure of a blower 18 that separately pressurizes the inside of the bag 1. The bag 1 is inflated and the bottom is lowered so that it is easy to put the next refuse.

If the shrinkage and expansion of the bag 1 are repeated during heating, the position of the dust is changed, and hot air is sucked from the catalyst 21, the dust can be uniformly heated. At the same time, since the deformation pressure is repeatedly applied, the total volume of the waste is further reduced. That is, the heating and drying time of the lower refuse can be shortened by such stirring.

A microwave may be used as a heating source,
In this case, the cylindrical container 2 must be made of a microwave-reflective material, and the bag 1 must be microwave-permeable. Microwaves are particularly suitable for heating garbage with a high moisture content, and are therefore an advantageous heating method when the garbage content is high.

[0023]

According to the present invention, garbage is reduced in volume and storage at home becomes easier. In addition, transportation and collection by local governments will be easier, and securing landfills will be easier.
