[0027] The working principle of this utility model:
[0028] When light and heavy materials are discharged from the outlet at the tail end of the drum screen, a high-power fan is used to blow out light materials such as plastics and woven fabrics with low density from the mixture. The blown light materials fall into the light material belt conveyor under the action of wind and gravity and are transported away by it. Heavy materials such as bricks, tiles and stones with high density fall into the heavy material drop pit. In this way, light and heavy materials are separated and stored separately for the next step of utilization and processing.
[0029] When light materials such as plastics and woven fabrics fall from the screen outlet of the drum 1 together with heavy materials such as bricks, tiles and stones, the wind blown out by the high-power fan 2 blows out the light materials such as plastics and woven fabrics with lower density from the light and heavy mixture through the wind channel formed by the drum screen 1 and the front and rear windshields 4. These light materials fall into the light material belt conveyor under the action of wind, gravity and rigid mesh cover and are transported to the storage site by it. Heavy materials such as bricks, tiles and stones with higher density that cannot be blown by the wind fall directly into the heavy material belt conveyor or bounce on the light material belt conveyor and then fall on the heavy material belt conveyor, and are transported to the storage site by the conveyor and scraper. In this way, light and heavy materials are separated and stored in different places for the next step of utilization or processing.
