The present invention relates to a method and apparatus for sorting household waste using wind power, and more particularly, to classify household waste that is simply landfilled or incinerated into renewable energy and other renewable resources by type using wind power before landfilling or incineration; Relates to a device.

Generally, most of the household waste is disposed of by landfill or incineration.

However, in the case of landfills, there are problems of securing and reclaiming large-scale land for processing large amounts of waste at once, and soil environment problems due to leachate before stabilization.

In the case of incineration, it is possible to treat domestic waste in a relatively small site, but excessive facility costs as well as disposal of incineration residues have to be relied on for landfill, and there are problems with the atmospheric environment due to incineration.

Therefore, in order to solve such problems, the amount of landfill or incineration needs to be reduced, and most of these household wastes are classified at home, so if such efforts are not made to reduce household waste or correct classification, such a purpose can be achieved. Becomes difficult.

In the end, landfills or incinerators have to deal with domestic waste before final landfill or incineration, but it is difficult to process them mechanically, so that only selective classification is made by hand, and the rest cannot be landfilled or incinerated.

However, such household waste contains a lot of vinyl or plastic that can be used as a RDF (Refused Drived Fuel), and a lot of recycled materials such as steel.

For reference, RDF has higher calories and cheaper price than anthracite coal, making it a good resource for alternative fuels and heating fuels of industrial and public institutions. As a result, local governments have recently attempted to use heating fuel using RDF, and the marketability is very bright.

Therefore, there is a need for a method of classifying vinyl or plastic to be supplied to a domestic waste fueling facility, but there is a problem that a systematic classification facility is not yet provided.

An object of the present invention for solving the above problems is to classify the household wastes that are simply landfilled and incinerated by type (non-combustible, flammable, size, scattered weight) recycled materials and RDF (Refused Drived Fuel; renewable energy) Solid fuel) to be incinerated to produce only the remaining landfills, and to reduce landfill and incineration targets by domestic wastes, to provide methods and devices for classifying household wastes using wind power to prevent soil and air pollution. have.

The present invention, which achieves the object as described above and the problem to remove the conventional drawbacks is an apparatus means for classifying by size and means for classifying by scattering weight as a device configuration for treating and recycling the domestic waste which is buried or incinerated The device means for sorting by the size is inclined at various angles according to the type of household waste supplied, consisting of an integrated vibration supply hopper and trommel sorting device configured to be formed at the same angle as the supply hopper and trommel screen The apparatus for sorting by scattering weight is characterized in that it comprises an air conveyor having a configuration for sorting the falling household waste according to the scattering weight.

In addition, the sorting method of the present invention having the configuration as described above supplies the municipal waste to the hopper to treat the municipal waste to be buried or incinerated and rotates through a trommel screen having a rubber net installed at the same angle or less to a certain size Discharging organic matters such as food and water having a size to the bottom and discharging the rest to sort by size;

After the sorting, it consists of the step of sorting the household waste discharged to the end of the trommel screen according to the scattering weight using wind power,

The sorting of the wind based on the scattering weight using the wind may include: a first sorting step of sorting the household waste that has fallen from the wind and falls into recyclables and landfills that cannot be recycled;

A second sorting step of selecting household wastes having heavy scattering weight from the household wastes introduced into the air conveyor by the wind as recycled materials and recycling materials for manufacturing RDF such as vinyl or plastic;

It consists of a three-stage sorting step of sorting and processing the household waste lightly scattered among the household waste introduced into the air conveyor by the wind as recycled materials and recycled materials for manufacturing RDF such as vinyl or plastic. It is characteristic of thought.

Hereinafter, the configuration and the operation of the embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a schematic plan view showing a configuration according to an embodiment of the present invention, Figure 2 shows a schematic front view showing a configuration according to an embodiment of the present invention, as shown the device configuration of the present invention Is integrally configured to be adjusted at the same angle to supply the household waste and the integrated vibration hopper (1) and trommel screen (2) for sorting by size;

A trommel discharge conveyor (3) for transporting household waste water of a predetermined size or more discharged from the integrated vibration hopper and the trommel screen;

A blower (4) installed by extending the blow nozzle (41) to the end of the trommel discharge conveyor to provide wind power for classifying household waste falling from the trommel discharge conveyor according to the scattering weight;

An air conveyor (5) at which the outlet openings (51, 52) having a lower opening are separated by a predetermined distance so as to sort household wastes scattered by wind at the end of the trommel discharge conveyor according to the weight of the waste;

A food discharge conveyor 6 for discharging organic matters such as food installed under the trommel discharge conveyor;

A primary sorting conveyor 7 installed between the trommel discharge conveyor and the air conveyor to separate living waste that has fallen from the wind and falls into recyclables and landfills that cannot be recycled;

A secondary sorting conveyor (8) installed at a lower portion of the outlet of the discharge holes installed in the air conveyor to discharge heavy household waste and sorting into recycled materials for recycling RDF manufacturing such as vinyl and plastics;

Among the outlets installed in the air conveyor, the scattering weight is installed at the lower portion of the outlet for discharging light household waste, and is composed of a tertiary sorting conveyor 9 for sorting with recycled materials such as recycled materials and RDF manufacturing materials such as vinyl or plastic.

The reason for moving the integrated vibration hopper and the trommel screen at the same angle in the above it is necessary to sort by various types above all in order to increase the degree of recycling of household waste having a variety of properties. To this end, the installation angles of the oscillating hopper as the input device and the trommel screen as the sorting device are adjusted to be the same. In the related art, since the angle of the input device and the sorting device is adjusted separately, its adjustment range is limited. However, in the present invention, the oscillating hopper and the trommel sorting device, which are input devices, are integrally installed on the same frame 101, and the input device and the sorting device can be simultaneously controlled by adjusting only the angle of the frame 101. Angle adjustment is to adjust the angle using a hydraulic or pneumatic cylinder, the specific configuration is omitted.

Accordingly, the range of angle adjustment of the frame has also been expanded to effectively perform screening according to various types of waste.

In other words, light waste is controlled at a high angle (8 degrees to 15 degrees) and heavy waste is adjusted at a low angle (1 degrees to 8 degrees) to effectively sort various types of waste by size.

The reason for limiting the value of the angle adjustment according to the weight as above is that if the light household waste is less than 8 degrees, the frictional force is large, and unless there is a forced conveying device such as a conveyor, the household waste does not move to the next position, If it is larger than 15 degrees, it is not sequential sorted and slid down.

In the case of heavy household waste, if it is larger than 8 degrees, it cannot be classified sequentially but slid downward. If it is smaller than 1 degree, the household waste does not move to the next position unless there is a forced conveying device such as a conveyor. Because it is not.

Trommel screen, the sorting device is composed of a rubber net in contact with the household waste. In addition, the rubber net is a sorting net for sorting wastewater with high moisture content. The sorting net at the inlet side has a large size, and the sorting net at the outlet side has a small size. This configuration prevents clogging of the sorting network and facilitates sorting so that waste can be effectively sorted by size.

In Trommel screen, its size is less than 50mm, and water or household waste of size that is difficult to discriminate from wind or water is selected and discharged to the food discharge conveyor located at the bottom.

In the food discharge conveyor, organic matter such as food and small-sized irons are selected. That is, the food discharge conveyor (6) is transported a small size (less than 50mm) sorted on the trommel screen and recycled by separating the steel materials by a permanent magnet drum (not shown) installed at the end, and glassware is separated and recycled And the rest is organic waste such as food waste landfill.

In the vibrating hopper and the trommel screen, the domestic waste from which a certain size (less than 50mm-wind or water difficult to sort) of household waste is removed is a bottom of a trommel discharge conveyor for sorting and separating recycled materials according to the scattering weight using wind power. A blower is installed at the end and the blower nozzle 41 at the end thereof is installed at the end of the trommel discharge conveyor. At this time, the wind generated from the blower blade is connected to the tent 42 to be discharged from the end of the blow nozzle (41).

The blower may be configured to further include a device for adjusting the wind power according to the type of waste by installing a damper (not shown) to control the wind power in the suction line of the blower.

The household waste falling from the end of the trommel discharge conveyor drops to the lower part through the blowing force or is scattered by the blowing force and flows into the air conveyor passage.

That is, wastes (wind, glass, heavy wood, iron, household appliances, etc.) that beat the wind are dropped into the primary sorting conveyor, so that wood, household appliances, and recycled products are sorted and iron is installed at the ends of the primary sorting conveyor. Wastes that are difficult to separate using permanent magnet drums (not shown) and which are difficult to recycle are discharged through a primary discharge conveyor to landfill.

In addition, heavy wastes (fibers, light weight wood, plastics, etc.) among the wastes scattered by the wind are sorted and recycled from the secondary sorting conveyor at the bottom through an outlet formed at one point of the air conveyor. The remaining combustible waste, which is difficult to recycle, is installed by compressing the compressor (not shown) at the end of the secondary screening conveyor and transported to an incinerator, or manufactured by RDF with an RDF maker and recycled as a cement kiln fuel.

In addition, the lightest waste (paper, vinyl, plastic, etc.) discharged by wind power is separated from the three-way conveyor at the bottom through the discharge hole formed at the end of the air conveyor. The rest of the combustible waste is installed by compressing by installing a compressor (not shown) at the end of the tertiary sorting conveyor and transporting it to an incinerator, or by manufacturing an RDF with an RDF maker and recycling it as a cement kiln fuel.

The air conveyor is connected to the suction line (not shown) of the blower by covering the upper part of the air conveyor with a cover and forming a flow path (not shown) to the right to prevent the blowing wind is discharged to the outside and to recycle.
