Embodiment 1

[0022] see Figure 1~3 , in an embodiment of the present invention, a treatment device for soil heavy metal pollution used for ecological restoration, including a base substrate 2 and an upper bracket 1 arranged on the base substrate 2, a liquid medicine tank 15, a liquid collection tank 18 and a collection tank 19. The lower ends of the two poles of the upper bracket 1 are fixedly connected to the end faces of the base substrate 2 and the poles of the upper bracket 1 are provided with conveying rollers 3, and the conveying rollers 3 are surrounded by a conveying mesh belt 21, one of which conveys The wheel 3 is driven by the motor to rotate and drive the conveying mesh belt 21 to rotate around the winding wheel to convey the soil. The middle part of the upper support 1 is also provided with two side baffles 4 located at the sides of the conveying mesh belt 21 and the ends of the side baffles 4 It is fixedly connected with the support rod of the upper bracket 1, and the guide ...

Embodiment 2

[0028] The difference between the embodiment of the present invention and embodiment 1 is that the vertical shaft 6 is slidingly fitted with the rotating sleeve 5 and the upper bracket 1 is provided with an adjusting screw 25 whose end is rotatably connected thereto. A threaded sleeve 27 cooperating with it is provided, and a connecting sleeve 26 which is rotatably connected with it is set on the vertical shaft 6. The side of the connecting sleeve 26 is provided with a push-pull rod 28 whose end is hinged thereto. 27. The outer wall is hinged. The upper bracket 1 is also provided with a transmission rod shaft 30 and the transmission rod shaft 30 is driven to rotate by the stirring motor 7. The lower end of the transmission rod shaft 30 is provided with an incomplete bevel gear 31 and the incomplete bevel gear 31 is arranged on the adjustment wire. The two rotating bevel gears 29 on the rod 25 mesh alternately. When the stirring motor 7 drives the transmission rod shaft 30 to ro...

Abstract

The invention discloses a soil heavy metal pollution treatment device for ecological restoration, which comprises a base substrate, and an upper bracket, a liquid medicine box, a liquid collecting boxand a material collecting groove, which are arranged on the base substrate; two side baffles located on the side portions of the conveying mesh belt are further arranged in the middle of the upper support, wherein the ends of the side baffles are fixedly connected with upper support supporting rods; a storage box and a stirring assembly used for stirring soil on the conveying mesh belt are arranged at the top of the upper support, the storage box is located at one ends of the side baffles, and a discharging channel is formed in the bottom end of the storage box. The upper support is further provided with a liquid medicine spraying assembly, and the liquid medicine spraying assembly is connected to the liquid outlet end of a pump body arranged in the liquid medicine box through a liquid guide pipe. The device is simple in structure, soil is conveyed on the conveying mesh belt so that heavy metal treatment can be conducted continuously, the treatment effect is improved by increasing mixing of liquid medicine and the soil through stirring, heavy metal mixed liquid and the soil can be separated conveniently, efficiency is high, and operation is convenient.

Description

technical field [0001] The invention relates to the technical field of soil remediation treatment, in particular to a treatment device for soil heavy metal pollution used for ecological restoration. Background technique [0002] Soil heavy metal pollution is one of the major global environmental hazards and may enter the human food chain through crops. Unlike pollution from other organic compounds, heavy metal pollution is difficult to degrade naturally. Many organic compounds can be detoxified or eliminated through the physical, chemical or biological purification of nature itself. However, heavy metals are enriched. For example, when heavy metals such as lead and cadmium enter the soil environment, they will accumulate for a long time and destroy the self-purification ability of the soil, making the soil a "reservoir" of pollutants. Planting crops on this kind of land, heavy metals can be absorbed by plant roots, resulting in crop yield reduction or the output of heavy m...
