X-ray clean coal gangue inorganic sulfur water-free separation equipment

Abstract

The invention discloses an X-ray clean coal gangue inorganic sulfur water-free separation equipment. The technical gist of the present invention is that it includes programmable electrical interlocks arranged at four different altitudes, raw coal lump coal supply system, large-grain linear vibrating screen system, small-grain linear vibrating screen system, gangue inorganic sulfur conveyor , Classified coal queuing system, desulfurization and gangue discharge conveyor, coal dust removal unit, photoelectric effect detection shielding room, X-ray photoelectric effect recognition and sorting instrument, wind coal separator, clean coal gangue inorganic sulfur conveyor. The invention adopts modular production and forms a water-free separation raw coal or lump coal production line. It processes raw coal or lump coal into low-sulfur, low-ash fine lump coal and low-sulfur, low-ash fine coal at the coal mine wellhead by using an anhydrous process and low coal preparation cost The fine coal can greatly improve the economic benefits of coal mines and the environmental benefits of coal-fired users; the invention can also use an anhydrous process to separate ferrous metal mineral products and non-ferrous metal mineral products.

Description

technical field [0001] The invention belongs to coal mine wellhead or ground coal transportation line, which uses photoelectric effect and water-free technology to remove medium coal, gangue and inorganic sulfur in raw coal or lump coal, and processes raw coal or lump coal into low-sulfur, low-ash refined lump coal and low-sulfur coal. The invention relates to a separation equipment for low-carbon fine coal, in particular to a water-free separation equipment for inorganic sulfur in coal gangue in X-ray clean coal in civil non-power nuclear technology. Background technique [0002] So far, wet gravity coal washing machines have been widely used at home and abroad for coal preparation. The demand for circulating water is large, and the water taken away by clean coal is also large, resulting in water shortage in Shanxi, Mongolia, Shaanxi, Gansu and Ningxia The seven provinces of Qinghai, Qinghai and New Zealand have not yet built a large-scale coal preparation industry.

[0002] So far, wet gravity coal washing machines have been widely used at home and abroad for coal preparation. The demand for circulating water is large, and the water taken away by clean coal is also large, resulting in water shortage in Shanxi, Mongolia, Shaanxi, Gansu and Ningxia, which are cold and cold in northwest my country. The seven provinces of Qinghai, Qinghai and New Zealand have not yet built a large-scale coal preparation industry

However, the wind coal separator used in China can only use the anhydrous process to separate small-grained coals that are easy to separate, and cannot select medium-sized coals and hard-to-separate coals without water, which makes its market share very small.

And use 241 Am and 238 The intelligent anhydrous coal separator built by Pu can only process fine coal into easy-to-separate fine coal, and cannot enable coal mines to sell low-sulfur and low-ash fine fine coal to coal-fired users
