An alien matter of a reclaiming earth removing device using specific gravity difference

摘要

The subject innovation relates to a method of removing the foreign material removing apparatus and screened gravel with a difference in specific gravity to allow embedding again after removing the foreign objects within the range allowed by the laws, regulations and the re-digging earth and sand or gravel embedded. To this end, at a predetermined height inside the water is filled in the tank 10 to be screened gravel is put; Once the head is in the tank 10, the other end tank 10 is screw-transferring apparatus 30 provided inclined so as to be exposed to the outside; Is installed in parallel to the lower sumyeonwa is locked on the surface of the water of the tank 10, a rotatable cylindrical brush (42); In contact with the tank 10, rotating collection tank 40, which is floating foreign matter collected is conveyed by the brush 42; And it is provided in the surface region an air nozzle 22 is provided so as to discharge the air toward the brushes 42; is provided.
