Efficient soil purification device for heavy metal pollution

Abstract

The invention discloses an efficient soil purification device for heavy metal pollution, the efficient soil purification device comprises a bottom plate, the upper surface of the bottom plate is fixedly connected with a support frame, the inner wall, close to the top, of the support frame is fixedly provided with a mixing box, the top in the mixing box is fixedly connected with a fixing sleeve, and the surface of the fixing sleeve is sleeved with a second gear; a fixing frame is fixedly connected to the top of the mixing box, a second motor is fixedly mounted at the top in the fixing frame, amounting rod is connected to an output shaft of the second motor, the end, close to the mixing box, of a spiral feeding pipe extends into the mixing box, and a crushing box is connected to the upper surface of the end, away from the mixing box, of the spiral feeding pipe. By means of turnover and rotation of stirring rods and shape setting of the stirring rods, the mixing range is widened, meanwhile, the mixing strength is improved, and therefore the soil purification efficiency of chemical agents is greatly improved.

Description

technical field [0001] The invention relates to the technical field of soil treatment, in particular to a high-efficiency soil purification device for heavy metal pollution. Background technique [0002] Soil purification refers to the measures and processes to reduce or eliminate pollutants and toxins in the soil through physical, chemical, and biological effects. The soil itself reduces the concentration of soil pollution and disappears through adsorption, decomposition, migration, and transformation. Process, soil heavy metal pollution refers to human activities, the content of trace metal elements in the soil exceeds the background value, and the excessive content caused by excessive deposition is collectively referred to as soil heavy metal pollution. The heavy metals in polluted soil mainly come from pesticides, wastewater, sludge and atmospheric deposition, etc. Excessive heavy metals can cause plant physiological dysfunction and nutritional imbalance; heavy metal pol...

AI Technical Summary

Problems solved by technology

The heavy metals in polluted soil mainly come from pesticides, wastewater, sludge and atmospheric deposition, etc. Excessive heavy metals can cause plant physiological dysfunction and nutritional imbalance; heavy metal pollutants have little mobility in the soil, are not easy to leach with water, and are not degraded by microorganisms. After entering the human body through the food chain, the potential hazards are extremely great. Special attention should be paid to prevent heavy metals from polluting the soil. The existing soil purification devices for heavy metal pollution have low stirring degree and low efficiency when mixed with chemical agents.
