Description

The foreign material quality sorting system which is contained in construction waste}

The present invention relates to a foreign matter sorting device included in the earth and sand of the construction waste, and more specifically, to be able to filter out the soil from the various kinds of construction waste supplied to the sorting device for the wet sorting, and to include it in the soil By collecting the foreign substances such as styrofoam, vinyl, paper or wood with low specific gravity from the soil by the blowing means and / or the suction means, the soil contained in the construction waste can be sorted and recycled without going through the wet sorting device. In order to increase the sorting efficiency of the wet sorting device, the sorting cost can be reduced.

In general, various construction wastes of various sizes and materials generated from rubble and construction sites of various buildings are sent to a separate wet sorting device for recycling so that they can be partially recycled by their size.

As such, the construction waste supplied to the wet sorting device for recycling is composed of soils having a small particle size of about 30 to 50%, and the rest constitutes various types of wastes having a certain size. Even small soils were sent to the wet sorting device together with various wastes in the form of agglomerate to perform wet sorting or to separate the soils separately.

However, when the soil having a small particle size is classified by the wet sorting device, the soil is deposited on the inner bottom of the tank of the wet sorting device. Therefore, the efficient sorting of the construction wastes is required. Not only can it be done, but the waste sorting takes much time, so the sorting cost of construction waste becomes expensive, and the soil sorting system causes frequent breakdown of the wet sorting equipment. There was a problem such as the need to stop the operation of the equipment from time to time, and in the case of classifying soils containing foreign matters from construction wastes, various foreign matters are still included in the classified soils. We cannot recycle and just throw up earth and sand The problem was that such should be disposed of.

Therefore, an object of the present invention is to classify the soil in advance before the wet classification of various construction waste for recycling as described above, blowing and / or foreign matter such as low-specific vinyl, styrofoam, paper and wood contained in the soil It is possible not only to recycle pure soil, but also to make sure that the soil is classified as pure soil without going through the wet sorting device by obtaining the pure soil that can be recycled from the soil by suction means. It is to provide a foreign matter sorting device included in the earth and sand of the construction waste that can effectively prevent the fall of the classification efficiency of the wet sorting device to be more efficiently and economically classified as a construction waste.
