Soil cleaning apparatus using variable draft tube agitator

Abstract

The present disclosure relates to a soil cleaning apparatus using a variable draft tube agitator, capable of improving the efficiency of cleaning contaminated soil and of increasing the capacity of cleaning treatment of contaminated soil, by optimizing a vertical agitating method using a draft tube, for the cleaning of contaminated soil. According to the present disclosure, the soil cleaning apparatus using a variable draft tube agitator comprises: a reaction tank which provides a space for cleaning contaminated soil and a space for attaching the variable draft tube; a variable draft tube which is provided in the reaction tank to induce vertical agitation of the contaminated soil, and which has a lower end of which the height can be selectively adjusted; and an impeller which is attached to the inner space of the variable draft tube.
