Description

A uniform stirring device for contaminated soil treatment

technical field

The utility model relates to the technical field of stirring equipment, in particular to a uniform stirring device for the treatment of polluted soil.

Background technique

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, cyanide, petroleum, synthetic detergents, and harmful microorganisms brought by urban sewage and sludge. When the soil contains too many harmful substances and exceeds the self-purification capacity of the soil, It will cause changes in the composition, structure and function of the soil, inhibit the activity of microorganisms, and gradually accumulate harmful substances or their decomposition products in the soil through "soil → plant → human body", or indirectly through "soil → water → human body" absorbed by the human body , to the extent of endangering human health, that is soil pollution. During soil treatment, it is necessary to adjust the treatment agent for stirring and mixing to adjust the soil, so it is necessary to use a stirring device, such as a polluted soil treatment disclosed by Authorized Announcement No. CN206561033U The uniform stirring device includes a first box body and a second box body, the second box body is provided at the left end of the first box body, the left end of the second box body is provided with a second motor, and the right end of the first box body is provided with a second motor. There is a first motor, the inner side of the second box body is provided with a rotating shaft connected with the second motor, the inner side of the first box body is provided with a rotating drum connected with the first motor, and the outer side of the rotating drum is evenly provided with a plurality of stirring blades, The inner side of the second box body is provided with a spiral blade on the rotating shaft, and the inner side of the rotating drum is provided with a plurality of pulverizing knives evenly staggered on the rotating shaft, which can be used for rapid and uniform stirring of the contaminated soil treatment and improve the effect of the contaminated soil treatment.
