GRAVITY SELECTION PURIFICATION APPARATUS USING NATURL GRAVITY SEDIMENTATION FOR FINE SOIL CONTAMINATED WITH HEAVY METAL

摘要

The present invention relates to an apparatus for separating and purifying contaminated soils containing heavy metals, and more specifically, to natural gravity sedimentation for soils contaminated with heavy metals, including arsenic, by splatters generated during the smelting process, such as soils around smelters. The present invention relates to a separation and extraction purification apparatus for heavy soils containing fine metals, which is capable of separating and purifying contaminated soils concentrated with heavy metals by using specific gravity selection characteristics. A main body consisting of a head; An inlet pipe and an outlet pipe installed at a lower side of the hopper part of the main body to introduce and discharge contaminated soil; A nozzle assembly provided to be movable up and down inside the body; Hose connected to the nozzle assembly; provides a specific gravity screening device by natural gravity sedimentation of heavy metal-containing fine soil comprising a.
