Method for renovating and repairing soil in iron ore area

Abstract

The invention discloses a method for renovating and repairing soil in an iron ore area. The method comprises the steps that a soil excavating device excavates the soil in the iron ore area; excavatedsoil is guided into the separation mesh enclosure by the guide plate, meanwhile, the separation mesh enclosure rotates and enables the soil to be smashed, so impurities such as stones are conveyed tothe direction of the discharging end of the separation mesh enclosure, and the other soil falls down through the discharging notch; impurities such as stones are discharged through the impurity discharging mechanism; soil and iron ore impurities fall down into the soil beating and crushing mechanism through the discharging notch to be beaten and crushed; the crushed soil downwards falls onto the mounting shell; meanwhile, the belt wheel connecting assembly pulls the soil to move through the scraping plate, the soil finally falls off and returns to the ground again, the iron ore impurities areattracted to the outer surface of the mounting shell through the magnetic plate, and when the iron ore impurities move to the position over the iron ore storage shell, the iron ore impurities can fallinto the iron ore storage shell downwards due to the fact that the non-magnetic plate replaces the magnetic plate at the moment.

Description

technical field [0001] The invention relates to the field of ecological environment restoration, in particular to a soil restoration method in an iron mining area. Background technique [0002] Soil is a natural shelter and purification treatment site for various wastes. Soil accepts pollutants. When there are too many pollutants contained in the soil, which affects or exceeds the self-purification ability of the soil, the natural environment in the area will deteriorate. Cause serious damage, such as the soil environment near the iron ore area, due to the impact of iron and steel smelting, the soil near the iron ore area is doped with a large amount of iron ore impurities, after the iron ore veins are used up, resulting in the near iron ore veins The soil cannot grow plants. In addition, the soil in this area can also enter rivers, lakes and groundwater through rainwater washing, which easily causes water pollution and poses a great threat to the ecological environment and ...
