The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is further illustrated:
As shown in the figure, the antifreeze deicing technique of earth's surface, mine, a kind of severe cold area independence ore storage bin, by sealing unload chamber, ore deposit 9 and ore storage bin 10 in hot air source and hot blast transmission equipment are installed, to in ore storage bin 10 and go out mine mouth ore and carry out hot blast and heat, to prevent in ore storage bin 10 and to go out mine mouth ore, freeze, or icing ore is thawed.
Sealing unload chamber, ore deposit 9 and ore storage bin 10 in hot air source and the hot blast transmission equipment installed comprise high-temperature hot-air equipment 1, warm-air pipe 2, the flexibility parting bead 3 that keeps out the wind, hot blast manifold 4, high-temperature hot-air equipment 1 is arranged on and unloads chamber, ore deposit 9 inner orbit line one sides, at ore storage bin 10 top board places, make an opening through the individual through hole of N (N > 1), warm-air pipe 2 draws by 1 outlet of high-temperature hot-air equipment the individual through hole of N (N > 1) that is connected to ore storage bin 10 top boards, and warm-air pipe 2 outlets are introduced to ore storage bin 10 downwards through through hole, the flexibility parting bead 3 that keeps out the wind is arranged on longitudinal edge of ore storage bin 10 top boards, hot blast manifold 4 is drawn outdoor by warm-air pipe 2, along ore storage bin 10 exterior walls, lay to the opening part of vibration ore dumping machine 8, warm-air pipe 2 and hot blast manifold 4 are done insulation and are processed.
High-temperature hot-air equipment 1 can be selected various ways, as fuel hot air stove, steam heat-exchange fan, electric calorifier etc., can be according to mine existing resource situation, and that suits measures to local conditions selects most economical failure-free apparatus-form.If Newly-built mine selects electric calorifier plenum system more energy-efficient.This type of hot-air heater volume is little, and programming rate is fast, and heat efficiency is high, energy-conserving and environment-protective, and air quantity and range of temperatures can regulate and control separately, according to ore storage bin actual condition, can be interrupted or continual control use.
Warm-air pipe is selected many straight seam welded steel pipes built on stilts laying in parallel, and caliber and wall thickness are determined according to air quantity, blast.
The flexibility that is arranged on the longitudinal edge of the ore storage bin top board parting bead 3 that keeps out the wind is distinguished and admirable excessive for reducing.
By hot blast, heat, to prevent in ore storage bin and to go out mine mouth ore, freeze, or the process that icing ore is thawed comprise:
1), drying process: adopt when ore aqueous ingredients freezes more greatly and not yet in ore storage bin, according to ore storage bin volume and aqueous ingredients, regulate high-temperature hot-air device temperature and air quantity to make it, after the highest scope of drying efficiency, to be dried.
2), anti-freezing process: adopt while keeping ore not freeze in ore storage bin normal course of operation, high-temperature hot-air device temperature is adjusted to local heating of house temperature, air quantity regulates according to ore storage bin volume, makes equipment continue blowing to ensure that ore storage bin and surrounding space temperature are above zero.
3), thawing technique: adopt when ore or ore storage bin mouth ore have freezed adhesion in ore storage bin, regulate high-temperature hot-air device temperature and air quantity to make it, in the most effective scope of ice-melt, the regional sustained that freezes to be heated, until melt.
Process sequence comprises:
1) process sequence when, ore not yet freezes is: dry → antifreeze → ore storage bin mouth thaws.
2) process sequence that, ore has freezed is: and thaw in ore storage bin → ore storage bin mouth thaws → is dried → and antifreeze → ore storage bin mouth thaws.
During use: select different process sequences according to operating mode, when ore not yet freezes, first ore is dried to processing, start hot-air heater, system operation also promotes rapidly temperature and air quantity, by regulating pipe valve, temperature and air quantity are controlled to the highest scope of drying efficiency, at a high speed, the air-flow of high temperature heats ore, and its moisture content of being with is evaporated rapidly, the ore that drying is processed can be avoided freezing phenomenon.
Next process is that ore is carried out to antifreeze processing, regulate hot-air heater temperature to local heating of house temperature, according to ore storage bin volume adjustment air quantity, make equipment continue blowing to ensure that ore storage bin and surrounding space temperature are above zero, can make the entrained remaining moisture content of ore not freeze, reach antifreeze effect.
Because ore storage bin can not be accomplished to seal completely, contact with outside atmosphere going out mine mouth place ore especially, and the coefficient of volumetric expansion is little, top thermal current is difficult to pass through, easily cause freeze and with equipment adhesion.Hot blast manifold 4 can be drained to hot air the opening part of vibration ore dumping machine 8, directly to freezing ore, forces blowing ice-melt, the object of thawing to reach Hatch Opening.
The in the situation that in ore storage bin, ore just having freezed before dry, antifreeze, first to do the processing of thawing to ore in ore storage bin and ore storage bin mouth ore simultaneously, regulate hot-air heater temperature and air quantity to make it in the most effective scope of ice-melt, to freezing, regional sustained is heated, until melt, in ore storage bin and after ore storage bin mouth ore all thawed, the process sequence in the time of can repeating above-mentioned ore and not yet freeze.
