Apparatus and process for reclaiming wood from debris

摘要

Wood is removed from debris in processes alternately conducted in a pair of side-by-side water filled tanks. Each tank includes an inclined bottom defining a deep end where sinking materials settle and a shallow end. Water jets along two adjacent sides of each tank creating a flow of surface water and floating wood toward one corner of the shallow end where the wood accumulates and is removed. Runways along two sides of each tank support debris handling equipment. A conveyor under one runway transfers the sinking materials away from the tanks. The wood is comminuted and sized for use as fuel.
