Description

Technical Field

[0001] The utility model relates to the technical field of heavy metal soil treatment, and more specifically to a heavy metal soil pollution treatment device. Background Art

[0002] Heavy metal soil pollution refers to the phenomenon of soil pollution caused by excessive deposition of heavy metal elements in the soil due to human activities, which exceeds the background value. These heavy metal elements mainly include mercury, cadmium, lead, copper, chromium, arsenic, nickel, etc.

[0003] At present, when treating soil contaminated by heavy metals, the contaminated soil can be placed in a barrel, and by adding chemicals and clean water for mixing and stirring, the heavy metal substances on the soil surface are transferred to the aqueous solution, thereby achieving the purpose of washing and cleaning the soil. In order to promote the full contact between the heavy metal substances on the soil surface and the chemicals, stirring is usually used to promote the reaction. However, the traditional stirring device is usually fixed in the barrel, and its effective stirring range is small. In order to promote the full reaction, it usually takes a lot of time, which is not convenient for improving the treatment efficiency of heavy metal substances on the soil surface. In view of this, we propose a heavy metal soil pollution treatment device. Utility Model Content

A motor 1 can drive a rotating seat to rotate, so that a half-toothed ring 1 meshes with a gear 1 and drives the gear 1 to rotate, thereby driving the rotating shaft to rotate, thereby driving the stirring component to swing toward one side through the rotation of the rotating shaft. As the rotating seat rotates, the half-toothed ring 1 disengages from the gear 1 and simultaneously makes the half-toothed ring 2 mesh with the gear 1, thereby making the gear 1 rotate in the opposite direction, thereby driving the rotating shaft to rotate in the opposite direction, so that the stirring component swings toward the other side, which is beneficial to improving the effective stirring range of the stirring component and achieving the effect of reciprocating swing stirring on both sides of the stirring component, solving the problem that a traditional stirring device is usually fixed in a barrel, has a small effective stirring range, usually takes a lot of time to promote the full reaction, and is not convenient for improving the treatment efficiency of heavy metal substances on the soil surface.

With the rotation of the rotating seat, the half-toothed ring 1 disengages from the gear 1 and simultaneously makes the half-toothed ring 2 mesh with the gear 1, thereby making the gear 1 rotate in the opposite direction, thereby driving the rotating shaft to rotate in the opposite direction, so that the stirring component swings toward the other side, which is beneficial to improving the effective stirring range of the stirring component and achieving the effect of reciprocating swing stirring on both sides of the stirring component, solving the problem that the traditional stirring device is usually fixed in the barrel, its effective stirring range is small, in order to promote the full reaction, it usually takes a lot of time, and it is not convenient to improve the treatment efficiency of heavy metal substances on the soil surface.
