PROBLEM TO BE SOLVED: To facilitate taking-out of floats by avoiding the situation of damage to equipment due to rubble and to easily and smoothly perform taking-out of sediments by sorting the sediments into large and small sizes.SOLUTION: A rubble sorting system includes a separating water tank Ta having a water tank body 1 into which the rubble G including the floats Gf floatable on water W and the sediments Gs sedimenting in the water W is thrown and in which the thrown-in floats Gf and the sediments Ga are separated due to specific gravity difference. The system provides a screen 10 which receives the sedimented sediments Gs on the side of a bottom part 4 of the water tank body 1, passes the sediments Gs of a prescribed size or less and filters off and removes them. The system discharges the water W and the sediments Gs passing through the screen 10 through a discharge pipe 13 to a storage tank Tb, and takes out the sediments Gs sedimenting in the storage tank Tb with a screw conveyor 40 so as to collect them.COPYRIGHT: (C)2013,JPO&INPIT【課題】 瓦礫による機器の損傷の事態を回避し、浮揚物体の取り出しを容易にするとともに、沈降物体を大小に分別できるようにしてこの沈降物体の取り出しも容易かつ円滑に行うことができるようにした。【解決手段】 水Wに浮揚可能な浮揚物体Gf及び水Wに沈降する沈降物体Gsを含む瓦礫Gが投入され、この投入された浮揚物体Gfと沈降物体Gaとを比重分離する水槽本体1を有した分離水槽Taを備え、水槽本体1の底部40側に、沈下した沈降物体Gsを受けるとともに所定の大きさ以下の沈降物体Gsを通過させて濾別するスクリーン10を設け、このスクリーン10を通過した水W及び沈降物体Gsを排出管13を介して貯留槽Tbに排出し、貯留槽Tb内に沈下した沈降物体Gsをスクリューコンベア40で取り出して集約できるようにした。【選択図】 図1
