JPH06183507A - Disposal method and device for household refuse - Google Patents

Abstract

PURPOSE:To deform refuse into an easily collected shape at home by placing the refuse, containing a thermoplastic resin product, in a vessel compressed in a condition heated to a specific temperature. CONSTITUTION:A home refuse disposal machine A is vertically set up, to put normal refuse and thermoplastic resin product refuse from a refuse input port 3. When the refuse containing this thermoplastic resin product is increased to a part in the vicinity of the refuse input port, after heating a piston up to 80-150 deg.C by electrifying an electric heater 24, a motor 21 is electrified, and a rotary unit 22 is rotated to move the piston 2 downward. Then, the refuse containing the thermoplastic resin product is heated, and the thermoplastic resin product is melted, compressed and contracted by adhesion of thermoplastic resin. The refuse, left as placed in this condition, is cooled by interrupting electrification of the heater 2. Thereafter, the motor 21 is electrified, and after moving the piston 2 in an upward direction, a bottom wall 4 is opened to be rotated with a rotary shaft 41 serving as the center, to take out the refuse 5.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a domestic waste disposal method and a domestic waste disposal apparatus. More specifically, the present invention relates to a household waste treatment method including a thermoplastic resin product and a household waste treatment apparatus used in this waste treatment method.

[0002]

2. Description of the Related Art Conventionally, household waste has been collected and processed by local governments.

[0003]

However, since various kinds of household waste are included, it is difficult to collect and dispose of them.

In particular, thermoplastic resin products such as an ethylene resin film used as a bag and a styrene resin foam used as a cushioning material are bulky and have been difficult to recover.

Therefore, an object of the present invention is to provide a domestic waste treatment method and a household used in this waste treatment method, which can easily form the waste containing such a thermoplastic resin product at home. An object of the present invention is to provide a garbage disposal device.

[0006]

The present invention has been made to solve the above problems and achieve the above objects, and the method of the present invention is to put dust containing a thermoplastic resin product in a container,
The dust is compressed while being heated to 80 to 150 ° C.

Further, in the apparatus of the present invention, a dust inlet is provided on the side wall of the tubular body, and a piston for moving the inside of the tubular body from one to the other with the dust inlet being provided is provided, and the other side of the tubular body is provided. The bottom wall is attached to the end face of the openable and closable, and the electric heater is attached to at least one of the bottom wall, the piston, and the side wall.

In this apparatus, if the inner surface of the side wall of the cylindrical body, the inner surface of the bottom wall, and the inner surface of the piston are coated with a resin having a good mold release property such as a fluororesin such as Teflon resin or a silicone resin, the molten heat will It is convenient because no plastic resin is attached.

The dust containing the thermoplastic resin product in the present invention refers to a mixture of dust such as paper and the thermoplastic resin product, but those containing 50% or more of the thermoplastic resin product are small when the dust is heated and compressed. Therefore, it is preferable that the thermoplastic resins adhere to each other or the thermoplastic resin and the dust such as paper adhere to each other sufficiently, and when they are cooled, they do not grow again.

[0010]

The operation of the domestic waste treatment method of the present invention will be described. Since the softening point or melting temperature of a commonly used thermoplastic resin product such as an ethylene resin film or a styrene resin foam is 80 to 150 ° C, Put the dust containing the thermoplastic resin product in a container, and put this dust at 80 to 150 ° C.
When heated, the thermoplastic resin product softens or melts. As described above, when the dust containing the thermoplastic resin product in the heated state is compressed, it can be easily compressed with a small pressure, and the thermoplastic resins are adhered to each other or the thermoplastic resin and the dust such as paper are adhered, and the volume is extremely large. Get smaller.

When the dust having a reduced volume is cooled, it solidifies while the volume is reduced. Therefore, when the dust is taken out, the dust containing the thermoplastic resin product can be easily collected.

Further, the operation of the household waste disposal device of the present invention will be explained. Since the side wall of the tubular body is provided with a dust input port, dust containing a thermoplastic resin product is input from this dust input port. .

After that, since a heater is attached to at least one of the bottom wall, the piston, and the side wall of the tubular body, the heater is energized to heat the tubular body to a temperature of 80 to 150 ° C. To do.

In the household waste disposal device of the present invention, since the piston capable of moving from one side to the other inside the tubular body sandwiching the dust input port is provided, when the piston is moved from one side to the other in this state. The thermoplastic resin product in the dust is heated to 80 to 150 ° C. to be softened or melted, the dust containing the thermoplastic resin product can be easily compressed, and the thermoplastic resin products can be compressed with each other or with the thermoplastic resin and the paper. The dust adheres and the volume becomes extremely small.

In this state, the heating is stopped and it is left for a while. Then, the dust containing the thermoplastic resin product is solidified in a compressed state, and the volume becomes extremely small. Further, in the household waste disposal device of the present invention, since the bottom wall is rotatably attached to the other end surface, the dust containing the thermoplastic resin product thus solidified is rotated on the bottom wall. It can be taken out easily by opening it.
