Heavy metal contaminated soil remediation device

Abstract

The invention discloses a heavy metal contaminated soil remediation device which comprises a storage barrel, a conveyor belt, a treatment seat, a connecting plate and a bucket, wherein two pairs of first traveling wheels are symmetrically arranged on two sides of the bottom end of an outer side wall of the treatment seat; and the connecting plate is welded on one side of the bottom end of the outer side wall of the treatment seat. A pulley matched with a guide seat is arranged on a connecting rod at one end of the screening bucket, and a movable sleeve is arranged on the outer side of a guiderod in a sleeving manner on the outer side wall of the screening bucket. On one hand, by utilizing guide of a bevel end of the guide seat, the screening bucket is matched with a reset spring at the other end of the screening bucket in a process of driving the screening bucket to rotate by a motor, so that the screening bucket can sway from side to side in the rotating and screening process, and the screening efficiency and the screening effect are improved; on the other hand, a second magnetic block having the same magnetism as a first magnetic block is arranged on the top of the movable sleeve, so that the movable sleeve enabling the screening bucket to rotate to a position just under the first magnetic block has a vibratory cleaning effect on the screening bucket, and blockage of sieve pores is avoided.

Description

technical field [0001] The invention relates to the technical field of soil remediation, in particular to a heavy metal contaminated soil remediation device. Background technique [0002] Pesticides, chemical fertilizers and mulch are important agricultural materials, which play a major role in promoting the development of agricultural production. However, long-term unreasonable application often leads to heavy metal pollution in the soil. Most of the pesticides are organic compounds, and a few are organic-inorganic compounds. Or pure minerals, individual pesticides contain heavy metals such as Hg, As, Cu, Zn in their composition, heavy metal elements are the most reported pollutants in fertilizers, nitrogen and potassium fertilizers contain low heavy metal content, and phosphate fertilizers contain more harmful Heavy metals, heavy metals in compound fertilizers mainly come from the masterbatch and the processing process. [0003] Soil heavy metal pollution has the characte...
