Abstract

The invention discloses an environmental-friendly treating and screening device for contaminated soil. The environmental-friendly treating and screening device for contaminated soil comprises a feeding pipe, a stirring tank, a medicament adding tube, a pulverizer, a heater, a stirring motor, a revolving shaft, a stirring blade, an air collecting tank, an electrode bar, a screening box, a first sieve plate, a second sieve plate, a cam and a feed delivery pipe. The feeding pipe is arranged at the top end of the stirring tank. The pulverizer is arranged in the stirring tank. The medicament addingtube is arranged at the top end of the stirring tank. The heater is arranged on the inner wall of the stirring tank. The electrode bar is arranged in the stirring tank. The stirring motor is arrangedin a clapboard cabin. The top end of the stirring tank communicates with the air collecting tank through a breather pipe. The sieve plates are obliquely arranged in the screening box. The sieve plates are moveably connected with the inner wall of the screening box. The cam is arranged at the lower part of the sieve plates. The effect and efficiency of soil treatment are improved, and the environmental protection effect is improved. Soil is screened in classification, and soil with different particle sizes is used differently. The environmental-friendly treating and screening device for contaminated soil is simple in structure, convenient to use, and beneficial to popularizing.

Description

technical field [0001] The invention relates to an environmental protection equipment, in particular to a screening device for environmental protection treatment of polluted soil. Background technique [0002] Pollutants produced by activities enter the soil and accumulate to a certain extent, causing soil quality to deteriorate, and then causing some indicators in crops to exceed national standards, which is called soil pollution. There are various ways for pollutants to enter the soil. Pollutants contained in exhaust gas, especially particulate matter, settle to the ground and enter the soil under the action of gravity. Wastewater carries a large amount of pollutants into the soil. Pollutants in solid waste directly enter the soil or Its exudate enters the soil. Chief among these is soil pollution from sewage irrigation. Extensive use of pesticides and chemical fertilizers has resulted in a decrease in soil organic matter content and soil compaction, which is also one of...
