Abstract

The invention provides a self-cleaning heat exchange type tailing dam comprising a dam body and aqueducts pre-buried at the bottom of the dam body; the aqueducts are provided with a plurality of heatexchange units in the length direction; each heat exchange unit comprises a heat exchange pipe, an end cover and a U-shaped water seepage drainage pipe; the bottom of the water seepage drainage pipe communicates with the aqueducts, and the top of the water seepage drainage pipe penetrates the dam body so that an open end is formed; the water seepage drainage pipe is provided with a plurality of water seepage drainage holes; the heat exchange pipe is internally arranged in the water seepage drainage pipe in a sleeving manner; the end cover is arranged outside the heat exchange pipe in the sleeving manner, and can be slid in the water seepage drainage pipe along the heat exchange pipe; the end cover is provided with a clean sleeve; the inside wall of the clean sleeve is provided with a brushradially extending inward; the brush abuts against the peripheral surface of the heat exchange pipe; and the dam body is provided with a driving device used for driving the end cover to slide. According to the self-cleaning heat exchange type tailing dam provided by the invention, the heat exchange pipe is arranged in the water seepage drainage pipe in the sleeving manner, and facilitates heat exchange.

Description

technical field [0001] The invention relates to the field of tailings dams, in particular to a self-cleaning heat-exchanging tailings dam. 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] Since the tailings pond requires seepage drainage, the tailings dam has the function of seepage drainage, and there is water flowing in the tailings dam all year round, which can...
