Abstract

The invention discloses a device for treating heavy metal polluted soil, which includes a hopper and a feeding device, and the feeding device includes a fan, a fixing seat, a feeding pipe, a discharge pipe, a supporting seat, a connecting pipe, a top cover, a stirring device and Closing device, the bottom of the fan is fixed with a fixed seat, the output shaft of the fan is connected to one end of the feeding pipe, the other end of the feeding pipe is sealed, and a plurality of discharge pipes are equidistantly arranged on the feeding pipe, Therefore, both ends of the feeding pipe are fixed with support bases, the hopper is fixed on the end of the feeding pipe close to the fan through the connecting pipe, the top of the hopper is fixed with a top cover, and a stirring device is fixed on the top cover. For the device for the treatment of heavy metal polluted soil, a motor is fixed on the upper end of the top cover. The rotation of the motor can drive the rotating shaft to rotate, and then the improving agent can be stirred through the rotating shaft, so as to prevent the improving agent from clogging when feeding and ensure the feeding. Uniformity.

Description

technical field [0001] The invention relates to the technical field of soil treatment, in particular to a device for treatment of heavy metal polluted soil. Background technique [0002] Soil heavy metal pollution refers to the content of trace metal elements in the soil exceeding the background value and excessive deposition due to human activities, which are collectively referred to as soil heavy metal pollution. Heavy metals refer to metals with a specific gravity equal to or greater than 5.0. Such as Fe, Mn, Zn, Cd, Hg, Ni, Co, etc.; As is a metalloid, but because its chemical properties and environmental behavior are similar to heavy metals, arsenic is often included when discussing heavy metals. It is directly included in the scope of heavy metals. Due to the high content of iron and manganese in soil, it is generally considered that they are not soil pollution elements, but under strong reducing conditions, the toxicity caused by iron and manganese has also attracted...
