Rapid treatment device with automatically soil turning and spraying functions for heavy metal contaminated soil

Abstract

The invention discloses a rapid treatment device with automatically soil turning and spraying functions for heavy metal contaminated soil. The rapid treatment device comprises a fixing plate and a soil turning spraying roller, wherein a pushing handle is arranged on the right side of the upper end of the fixing plate; a first fixing shaft is arranged on the left side of the soil turning spraying roller; a roller body of the soil turning spraying roller is provided with soil turning knifes which are distributed in an array mode, each array-distributed spraying head is arranged at the position,arranged on a gap between the soil turning knives, on the soil turning spraying roller, the inner sides of the spraying heads communicate with communicating pipes, and the inner sides of the communicating pipes communicate with a second liquid passing cavity; a second rotating shaft is fixed to the right side of the soil turning spraying roller, a second fixing rod is arranged on the second rotating shaft, and the right side of the second rotating shaft is inserted into a fixing frame in a penetrating mode; and the fixing frame communicates with a first connecting pipe, the right side of the first connecting pipe communicates with a second connecting pipe, the upper end of the second connecting pipe communicates with a pumping pump, and the left side of the pumping pump communicates with achemical box through a connecting pipe. According to the rapid treatment device, the heavy metal contaminated soil can be rapidly treated, meanwhile, the treated chemicals treat the soil more easilythrough the turned soil, so that the problem that surface caking treatment effect of the soil is poor is avoided.

Description

technical field [0001] The invention relates to a device for rapid treatment of heavy metal polluted soil, in particular to a device for rapid treatment of heavy metal polluted soil with automatic soil turning and spraying. Background technique [0002] Soil is an important part of the human environment and the basis of people's life and production. However, due to the rapid development of cities and industries in recent years, soil pollution has become one of the prominent environmental problems in our country. In particular, soil heavy metal pollution is the most serious. Soil heavy metal pollution mainly comes from the three wastes of industrial production such as mining and metal smelting, as well as the unreasonable application of sewage irrigation, pesticides, and chemical fertilizers. Soil heavy metal pollution not only leads to soil degradation, crop yield and quality reduction, but also heavy metals in the soil will be absorbed by plants, and when accumulated to a c...
