Double-circulation type soil pollution treatment device

Abstract

The invention discloses a double-circulation type soil pollution treatment device. The device comprises a processing shell, a liquid storage tank and a circulation cavity, a bottom plate is arranged at the bottom of the processing shell, an upper cover is arranged at the upper end of the processing shell, the middle of the upper cover is sequentially provided with a first motor, a stirring shaft,a spiral blade and crushing blades, and a spray pipe and high-speed wide-angle spray heads are arranged at the lower end of the upper cover; and the liquid storage tank is arranged on the right wall of the processing shell, walking wheels and a discharging pipeline are arranged at the lower end of the processing shell, a feeding pipeline and a liquid pump are arranged on the upper cover, the circulation cavity is formed in the left wall of the processing shell, the circulation cavity is provided with a second motor, a lifting rotating shaft and a circulating lifting blade, and a circulation material outlet and a circulation material return opening are connected between the circulation cavity and the processing shell. According to the device, soil can be efficiently crushed, the soil crushing and treating efficiency can be further improved through internal and external double lifting circulation, the high-speed wide-angle spray heads are used cooperatively to spray an agent, effective and full mixing can be achieved, and the treatment of soil pollution can be efficiently completed.

Description

technical field [0001] The invention relates to the field of soil pollution treatment, in particular to a double-cycle soil pollution treatment device. Background technique [0002] Due to the rapid growth of population and the rapid development of industry, solid wastes are continuously stacked and dumped on the soil surface, harmful waste water is continuously infiltrated into the soil, and harmful gases and floating dust in the atmosphere are also continuously falling into the soil with rainwater, resulting in soil pollution. Soil pollutants can be roughly divided into two categories: inorganic pollutants and organic pollutants. Inorganic pollutants mainly include acids, alkalis, heavy metals, salts, compounds of radioactive elements cesium and strontium, compounds containing arsenic, selenium and fluorine, etc. Organic pollutants mainly include organic pesticides, phenols, cyanides, petroleum, synthetic detergents, 3,4-benzopyrene, and harmful microorganisms brought by ...

AI Technical Summary

Problems solved by technology

[0003] In the existing devices, the treatment efficiency of soil pollution is relatively low, and the uniformity is poor. In many cases, the mixture of the treatment agent and the soil is not uniform enough, so the effect is relatively poor
