An environmental protection soil treatment device

Abstract

The invention discloses an environment-friendly soil remediation device. The soil remediation device comprises a box body, the upper portion of the box body communicates with a feeding pipe, a spiralfeeding roller is arranged in the feeding pipe, the bottom of the spiral feeding roller is fixedly connected with a throwing disc, a hitting plate is arranged at the position, located on the outer side of the throwing disc, of the box body, a smashing screen cylinder is arranged below the throwing disc, a center shaft is arranged in the smashing screen cylinder, a smashing knife and a scraping plate are fixedly connected to the center shaft, an annular spraying pipe is arranged below the smashing screen cylinder, and nozzles which are circumferentially distributed are arranged on the annular spraying pipe. Through the throwing disc and the hitting plate, soil blocks are hit and smashed, and subsequent soil smashing is facilitated; through the smashing screen cylinder, the scraping plate and the smashing knife, the soil can be subjected to further smashing and screening, and the soil particle smashing effect is ensured; the annular spraying pipe and the atomizing nozzles are arranged, asoil repairing agent and falling soil particles can be sufficiently mixed, the mixing effect is improved, and the use amount of the repairing agent can be reduced.

Description

technical field [0001] The invention relates to the field of environmental protection, in particular to an environmental protection soil treatment device. Background technique [0002] Soil pollution in China has threatened the sustainable use of land resources and the ecological security of agricultural products. The farmland polluted by organic pollutants in the country has reached 36 million hectares. The types of pollutants include petroleum, polycyclic aromatic hydrocarbons, pesticides, and organic chlorine. It also pollutes a large area of ​​land; in the Shenfu petroleum sewage irrigation area, the content of polycyclic aromatic hydrocarbons in the surface layer and bottom soil both exceeds 600mg / kg, causing serious pollution of crops and groundwater. There are 20 million hectares of land polluted by heavy metals across the country, of which more than 700,000 hectares are seriously polluted, and 130,000 hectares of which have been abandoned due to excessive cadmium co...

Problems solved by technology

[0003] The traditional heterotopic soil treatment method is to use a stirring mechanism to fully mix the soil remediation agent with the soil, but the mixing effect is not good, and the amount of remediation agent is consumed.
