The present invention collects and washes soil contaminated with various contaminants such as organic matter, oil and heavy metals, and cleansed soil which can be reused as a land cover at the place where it was originally collected or reclaimed for other requirements. It is about.

Conventional contaminated soil washing equipment includes organic soil contaminated soil washing apparatus for washing soil contaminated with organic substances such as dioxins and pesticides, oil contaminated soil washing apparatus for washing soil contaminated with oil such as oil and heavy metals. The heavy metal contaminated soil washing apparatus for washing the soil was constructed separately to wash the contaminated soil.

The conventional contaminated soil washing apparatus as described above not only requires a lot of facility investment costs due to the complicated equipment, but also contaminants adsorbed on the micro-contaminated soil having a small particle size because various contaminants are strongly compressed onto the surface of the micro-soil. The separation and separation of the material is difficult, so there was a disadvantage in that the conventional soiling process cannot effectively clean the contaminated soil.

In order to solve the above problems, the present invention not only can wash soil contaminated with various pollutants such as organic matter, oil and heavy metals, but also, especially, the soil is strongly adsorbed on the surface of micro soil having small particle size. It is an object of the present invention to provide a contaminated soil washing apparatus that can easily wash materials, discharge the washed soil by size, and have a simple structure and excellent washing efficiency of contaminated soil.

In order to achieve the above object, the present invention has a particle diameter of 10 mm in the primary screen 2 having a diameter of 10 mm that is vibrated by the vibration motor 1 and washes the soil by the water sprinkler 17. The above soil is screened and supplied to the secondary screen 7 having a diameter of 10 mm,

Soil less than 10 mm in diameter that passed through the primary screen 2 having a diameter of 10 mm is washed with a rotary washing device 4 in which a rotating hole 12 in which a pin 13 protrudes from the outside is rotated and stirred. To the secondary screen 7 having a diameter of 10 mm,

The soil having a diameter of 10 mm or more supplied from the primary screen 2 having a diameter of 10 mm and the soil smaller than 10 mm of the particle size supplied from the rotary washing machine 4 are vibrated by the vibration motor 6, and then sprayed by the sprinkler 17. The soil is washed with a secondary screen (7) having a diameter of 10 mm to wash the soil, and the soil having a particle diameter of 10 mm or more is discharged to the outside, and the soil having a particle size of less than 10 mm is supplied to the tertiary screen (8) with a diameter of 3 mm.

Soil less than 10 mm in diameter that passed through the secondary screen 7 having a diameter of 10 mm is washed with a tertiary screen 8 having a diameter of 3 mm, and soil having a particle size of 3 mm or more is discharged to the outside, and soil less than 3 mm in diameter is It is configured to discharge to the discharge pipe 10 through the hopper (9).

In addition, a protective cap 18 is attached to the pin 13 mounted on the outer circumferential surface of the rotary hole 12.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.
