AI Technical Summary
In existing technologies, the mixing mechanism cannot adjust the spraying area and the mixing area in real time according to the degree and distribution of pollution in the bottom sediment, resulting in waste of reagents and low treatment efficiency. Furthermore, it cannot dynamically adjust the spraying intensity according to the heavy metal content, leading to unstable treatment results.
An adjustable rinsing intensity stirring mechanism was designed. By linking the vertical positions of the stirring mechanism and the spraying mechanism, a three-dimensional dynamic coupling between the eluent spraying area and the stirring action area is achieved. A heavy metal detector is used to monitor and adjust the spraying intensity and stirring position in real time to ensure accurate coverage and synchronous matching.
It achieves precise coverage of the processing space, avoids blind spots and regional misalignment, improves reagent utilization and processing efficiency, and ensures the stability and uniformity of the processing process.
