Soil remediation and screening device

Abstract

The invention discloses a novel soil remediation and screening device. The soil remediation and screening device comprises a box body, and the box body is of an up-down penetrating structure. A first screening plate is arranged on one side wall in the upper portion of the box body in a downwards-inclining mode through first articulation pieces, a second screening plate is arranged on the other side wall in the lower portion of the box body in a downwards-inclining mode through second articulation pieces, and one side wall in the box body is parallelly opposite to the other side wall in the box body. A first discharging passageway is formed in the side wall, corresponding to a discharge end of the first screening plate, of the box body, and the discharge end of the first screening plate is exposed out of the first discharging passageway. A second discharging passageway is formed in the side wall, corresponding to a discharge end of the second screening plate, of the box body, and the discharge end of the second screening plate is exposed out of the second discharging passageway. According to the soil remediation and screening device provided by the invention, the screening effect is remarkable, the blocking phenomenon is avoided, and blocking clearing does not need to be conducted in the screening process.

Description

technical field [0001] The invention belongs to the technical field of soil restoration. Background technique [0002] According to the "National Soil Pollution Survey Bulletin" released in 2014, the overall soil environment in China is not optimistic, and the national soil pollution rate has reached 16.1%. While the soil environment problems of industrial and mining wasteland are prominent, the soil environment quality of cultivated land is even more worrying. Faced with the severe situation of soil pollution, the national legislation has been significantly accelerated. In addition to adding soil remediation to the new "Environmental Protection Law", the Ministry of Environmental Protection recently announced the new "Soil Environmental Quality Standards (Draft for Comment)", "Soil Pollution Prevention and Control Action Plan" (referred to as "Soil Ten Articles") ) formulation and implementation is also on the agenda. The large-scale soil pollution exceeds the standard an...
