Apparatus and method for removing low-specific waste and manufacturing circulating soil using rotary vortex during the intermediate treatment process of construction waste

摘要

The present invention relates to the removal of low-specific gravity foreign substances using rotating vortices during the intermediate treatment process of construction waste and to an apparatus and method for producing recycled soil. The present invention relates to a device and method for removing low-specific gravity foreign substances attached to recycled soil through physical impact and to removing low-specific gravity foreign substances using subsequent vortices. The purpose is to increase the removal efficiency of foreign substances and produce high purity recycled soil. The device for removing low-specific gravity foreign matter and producing circulating soil using a rotating vortex during the intermediate treatment process of construction waste according to the present invention includes a case (10) provided with an inlet at the circumference and an outlet for foreign matter and soil at the top and bottom; a liner 14 lining the lower inner peripheral surface of the inlet as the inner peripheral surface of the case; a rotating dispersion plate (20) rotatably installed inside the case below the inlet and rotating the soil input into the case to collide with the liner to primarily drop low-specific gravity foreign substances attached to the soil; It has a cylindrical structure and is equipped with a vortex wing on the inner peripheral surface, and is rotatably installed on the upper part of the inlet as the inside of the case to form a vortex at the upper part of the rotary dispersion plate, thereby forming a vortex at the top of the rotary dispersion plate, so that the bottom is separated from the soil and sand by the rotary dispersion plate. It includes a vortex rotor 30 that guides heavy foreign matter to the upper outlet in a secondary way and discharges it to the outside.
