Embodiment Construction
[0019] The specific embodiment of the present invention is further described below in conjunction with accompanying drawing:
[0020] As shown in the figure, an antifreeze and deicing process for an independent ore bin on the surface of a mine in a severe cold area, by installing a hot air source and hot air transfer equipment in the sealed ore unloading chamber 9 and the ore bin 10, the ore in the ore bin 10 and the ore outlet Carry out hot air heating, to prevent the ore from freezing in the mine bin 10 and the ore outlet, or thaw the frozen ore.
[0021] The hot air source and hot air transfer equipment installed in the sealed ore unloading chamber 9 and the ore bin 10 include high temperature hot air equipment 1, hot air pipe 2, flexible windshield spacer 3, and hot air branch pipe 4. The high temperature hot air equipment 1 is installed in the ore unloading On one side of the track line in the chamber 9, N (N>1) through holes are drilled on the roof of the mine bin 10, an...

The invention provides an independent ore bin antifreezing deicing process at a mine earth surface in a severe cold region. The method comprises the step of performing hot air heating for the interior of an ore bin and ores at an ore outlet by mounting a hot air source and hot air conveying equipment in a sealed ore unloading bin and the ore bin, thus preventing the interior of the ore bin and the ores at the ore outlet from icing or unfreezing the iced ores. Compared with the prior art, the independent ore bin antifreezing deicing process at the mine earth surface in the severe cold region has the beneficial effects that the process method is simple, the investment is less, a high temperature hot air source is introduced, the anti-freezing deicing aim is achieved by a reasonable, scientific and efficient ore bin hot flow arrangement mode, so the ores in the ore bin can be smoothly stored and transferred and the smooth operation of the mining work is ensured.
Description
technical field [0001] The invention relates to an antifreeze optimization process for mine bins in severe cold areas, in particular to an antifreeze and deicing process for independent mine bins on the surface of mines in severe cold areas. Background technique [0002] Since the founding of the People's Republic of China, as the national economy has gradually entered the fast lane of high-speed development, the mining scale of metal and non-metal mines in my country has developed by leaps and bounds. All kinds of rebuilt and newly built mines are spread all over the country, and the annual new production capacity is nearly 100 million tons. my country has a vast territory, with completely different geological and geomorphological characteristics, and regional climates vary greatly. Therefore, the diversity of physical and chemical properties of mine ore is caused. The factors that have the greatest impact on surface mines are their moisture content and ambient temperatur...
