AN ALIEN SUBSTANCE AND A DIFFERENTIAL CALCULUS REMOVAL DEVICE OF A CONSTRUCTION WASTE

摘要

A device for removing foreign materials and fine particles of the construction waste is provided to prevent fine particles from being frozen and deposited at the inside of a suction duct during discharging the fine particle separated from aggregates through the suction duct by the air supplied from a blower. A device for removing foreign materials and fine particles of the construction waste is composed of: vibrating screens(300,300') obliquely installed at the upper part of a transfer conveyor belt(500) in multiple stages; a blower(400) mounted between the vibrating screens; and a foreign material suction unit(100) installed at the upper part of the vibrating screens. The foreign material suction unit has a distributing tool(102) mounted on one side of a cover(101) covering the vibrating screens and a suction duct(103) installed on the other side. The distributing tool has an inclined panel(104) inclined upward and combined with the cover. Plural distributing plates(105) are combined with the inclined panel by a slide shaft. A blocking blade(107) is combined with a joining part of the cover corresponding to the lower end of the suction duct.
