Self-derusting tailings dam drainage system

Abstract

The invention provides a self-derusting tailing dam drainage system. The self-derusting tailing dam drainage system comprises a water guide pipe horizontally arranged; multiple U-shaped seepage drainage pipes are arranged on the water guide pipe in the length direction; the bottoms of the seepage drainage pipes communicate with the water guide pipe, and the tops upwards extend to form opening ends; multiple seepage drainage holes are formed in the outer peripheral surfaces of the seepage drainage pipes; derusting modules are mounted in the seepage drainage pipes, and comprise rails, grinding wheels, support tables and motors; one ends of the rails are inserted in from one ends of the seepage drainage pipes, and are inserted out from the other ends of the seepage drainage pipes; the other ends of the rails are free ends; the support tables slidingly sleeve the rails; the grinding wheels are rotationally connected with the support tables, and can slide in the seepage drainage pipes alongthe rails; and power output ends of the motors are in transmission connection with the grinding wheels. The self-derusting tailing dam drainage system polishes the inner walls of the seepage drainagepipes through the grinding wheels to prevent rust from blocking the seepage drainage holes to improve the drainage function of the seepage drainage pipes.

Description

technical field [0001] The invention relates to the field of tailings dams, in particular to a self-derusting tailings dam drainage system. Background technique [0002] The tailings dam is a structure formed by tailings accumulation and rolling to protect the tailings pond. It is divided into a tailings accumulation dam and an initial dam. The initial dam can be made into a permeable dam (which is conducive to the drainage and consolidation of tailings. In recent years used more) and impermeable dams (used more in the early stage in China), which play a great role in the protection and management of the mine environment. ore or other industrial waste. Unlike reservoirs, reservoirs require anti-seepage, while tailings ponds require seepage drainage, otherwise debris flows will easily form. [0003] In order to facilitate the drainage of tailings dams, seepage pipes are pre-buried in the existing tailings dams. The water flowing in the tailings dam is highly corrosive; aft...

Problems solved by technology

The existing drainage pipe does not have the function of derusting. After the drainage pipe is corroded, only the drainage pipe can be replaced
