AI Technical Summary
During the drainage process of existing mine drainage tanks, silt and sand are likely to accumulate at corners, affecting the drainage effect, and silt and sand containing minerals will cause mineral waste when discharged.
A mining underground drainage tank was designed, and the dredging components were used to include metal sensors, filters, baffles, motors, screws and levers. The metal sensors were used to detect whether the silt contained metal minerals. The filters and baffles controlled the silt to temporarily exist in the installation frame. The motor drove the screws and lever to unblock or transport the silt to the storage box to realize dredging and mineral collection at corners.
It effectively reduces the chance of blockage at the corners of the drain tank, and can collect and store mineral-containing silt and sand for subsequent screening and reduce mineral loss.
