The present invention relates to a sorting system for separating the waste contained in the soil and drying the sorting waste to remove the foreign matter to reduce the weight, more specifically, the soil separated from the sorting system is separated waste is discharged mixed waste Blowing up and dropping the soil and rubbish to separate the mixed waste into waste concrete, rubble and other small incineration and recycled waste to increase the recycling rate of waste and re-inject the sorting waste into the drying separator. The present invention relates to a waste sorting device that can be efficiently processed by reducing and sorting the wastes by recycling and incineration or landfill by separating and removing foreign substances.

In general, among the construction wastes generated at the construction site or the wastes that are already buried in landfills, recyclable resources are landfilled as they are not sorted. Therefore, the amount of reclaimed land is increased and the weight of garbage is high even after sorting. In addition, this causes excessive waste disposal costs, as well as leachate, odor, and scattering dust from landfilled waste, causing environmental pollution and waste of recyclable resources.

Therefore, the construction wastes and general wastes generated at the construction site are separated and sorted into recyclable resources, combustible incineration wastes and landfills, and only the waste which is not recyclable can be incinerated or landfilled, thereby greatly reducing the throughput of wastes and sorting garbage. It is necessary to efficiently process by minimizing the amount of incineration or landfill by re-injecting into the drying separator and drying and removing foreign substances to reduce the amount.

The present applicant separates and recycles the soil and aggregate from the construction waste or landfill waste, and separates the landfill waste and the waste for recycling and combustible incineration from the sorted waste waste so that only minimal waste can be reclaimed. As a technology to significantly reduce the amount of landfill and prevent environmental pollution, the Korean Patent No. 0404147 (a waste sorting device) has been registered and proposed.

The "preparation device for garbage separation" of the above-mentioned technology is installed with a venturi tube-type waste sorter using the wind speed of the blower to prevent the scattering of dust and the like, and the earth and recyclable materials that cannot be separated from the first sorter and By separating and reclaiming landfill waste, it is possible not only to prevent environmental pollution, but also to remove high-quality earth and sand through the sediment sorter with small particle size, while maintaining the amount of waste sorting work. It is configured to separate and sort the recycling waste made of metal material.

However, the pre-registered technology applies strong wind speed with the blower to the garbage falling from the first sorter to separate the light and heavy garbage into landfill and separate and sort the landfill waste, and at the same time, Although small stones are separated and sorted through a venturi tube-shaped sorting canister in the waste sorting machine, the separation effect of the light waste and heavy waste is reduced in the waste falling from the first sorting machine, and a lot of manpower is inputted. While sorting is difficult, it causes a problem that the conveyor is easily damaged by heavy waste.

The present invention is a technology devised to solve the problems according to the existing waste sorting device, the waste is a heavy waste weight by applying a blow while transporting and dropping the soil and rubbish is mixed waste that is separated and discharged from the sorting system By separating and sorting the waste into incineration and recycled wastes with low specific gravity, such as concrete, rubble, etc., the waste recycling rate is increased.
