Description
Technical field
The utility model belongs to mineral hot furnace raw material system, particularly relates to a kind of mineral hot furnace top filling hot blast energy-saving drying device.
Background technology
Mineral hot furnace top charging appts (feed bin) is a kind of storage facilities of even furnace charge, mainly plays material storing, buffering and proportionality action.Raw material directly enter the moisture that stove brings into will take away a lot of heat when vaporizing, and easily cause nonaqueous dust cleaner to stick with paste bag phenomenon to occur; The O of manganese ore thermal decomposition release
2easily cause totally-enclosed mineral hot furnace furnace atmosphere to worsen, or cause explosion accident to occur.Although traditional furnace charge drying system can by the decomposition O of value Mn oxide
2link is transferred to outside stove, but system footprint area is large, and investment is large, and cannot realize heat and expect, into stove, to cause energy waste.
Utility model content
The technical problems to be solved in the utility model: a kind of mineral hot furnace top filling hot blast energy-saving drying device is provided, directly enter the moisture that stove brings into and will take away a lot of heat to solve prior art raw material when vaporizing, although and easily cause nonaqueous dust cleaner to stick with paste bag phenomenon to occur and traditional furnace charge drying system can by the decomposition O of value Mn oxide
2link is transferred to outside stove, but system footprint area is large, and investment is large, and cannot realize heat and expect, into stove, to cause the problems such as energy waste.
Technical solutions of the utility model:
A kind of mineral hot furnace top filling hot blast energy-saving drying device, it comprises center feed bin, 1# belt one end is connected to proportioning station, the other end is connected with bifurcated hopper arrival end, bifurcated hopper outlet end is connected with 2# belt, 2# belt is connected with the feeding end of center feed bin, and center bin bottom discharge end is connected with material pipe.
Heat exchanger is provided with in the feed bin of center.
Feed bin side, center is provided with airduct, and hot-blast stove is connected with airduct by high-temperature blower.
Hot-blast stove is connected with coal gas gathering-device.
Bifurcated hopper is positioned at 2# belt top, and 2# belt is positioned at feed bin top, center.
Material pipe quantity is greater than one.
The beneficial effects of the utility model:
Owing to have employed technique scheme, compared with prior art, the utility model is specially adapted to, in the raw material system of large-scale totally-enclosed In The Sub-mergedfurnace of The Ferroalloys, also to improve on mineral hot furnace original structure.Pass through the utility model, the storage of mineral hot furnace raw material system, cloth and dry three kinds of functions are melted into a whole by mineral hot furnace top filling hot blast energy-saving drying device, apparatus structure is compact to design, reduced investment, save traditional raw material stoving system investments, do not take the land resource of plant area's preciousness, the separating twice in process had bad luck by minimizing furnace charge.The utility model effectively make use of the Gas Resource that totally-enclosed mineral hot furnace reclaims, and carry out drying and forewarm to furnace charge, heat expects can improve the working of a furnace into stove, shorten the heat, reduce alloy product specific energy consumption, improve efficiency of energy utilization and mineral hot furnace production efficiency, improve output.Dry the generation of expecting to avoid sticking with paste during dry-method dust removal of coal gas bag phenomenon into stove, the decomposition O of value Mn oxide
2link is transferred to outside stove, has ensured the processing safety of totally-enclosed mineral hot furnace.Solve prior art raw material directly to enter the moisture that stove brings into and will take away a lot of heat when vaporizing, although and easily cause nonaqueous dust cleaner to stick with paste bag phenomenon to occur and traditional furnace charge drying system can by the decomposition O of value Mn oxide
2link is transferred to outside stove, but system footprint area is large, and investment is large, and cannot realize heat and expect, into stove, to cause the problems such as energy waste.

Detailed description of the invention
A kind of mineral hot furnace top filling hot blast energy-saving drying device, it comprises center feed bin 4,1# belt 1 one end is connected to proportioning station, the other end is connected with bifurcated hopper 2 arrival end, bifurcated hopper 2 port of export is connected with 2# belt 3,2# belt 3 is connected with the feeding end of center feed bin 4, and center feed bin 4 bottom discharge end is connected with material pipe 5.
Heat exchanger 9 is provided with in center feed bin 4.
Center feed bin 4 side is provided with airduct 8, and hot-blast stove 6 is connected with airduct 8 by high-temperature blower 7.
Hot-blast stove 6 is connected with coal gas gathering-device.
The furnace charge mixed at proportioning station is delivered to bifurcated hopper 2 by 1# belt 1, furnace charge is transported to 2# belt 3 under bifurcated hopper 2 acts on, finally enter center feed bin 4, the material pipe 5 that furnace charge connects through bottom after center feed bin 4 completes heating, drying joins in mineral hot furnace burner hearth to be smelted.
The coal gas of totally-enclosed mineral hot furnace collected by coal gas gathering-device, after the coal gas collected burns in hot-blast stove 6, hot blast blasts the heat exchanger 9 in center feed bin 4 under high-temperature blower 7 acts on through airduct 8, hot blast completes heat exchange in heat exchanger 9, furnace charge is gradually by heating, drying, and tail gas is back to hot-blast stove 6 and is reheated utilization.
Bifurcated hopper is positioned at 2# belt top, 2# belt is positioned at feed bin top, center, adopt such arrangement, the present invention adopts this structural design, has compact advantage, the storage of mineral hot furnace raw material system, cloth and dry three kinds of functions are melted into a whole, apparatus structure is compact to design, reduced investment, saves traditional raw material stoving system investments, do not take the land resource of plant area's preciousness, the separating twice in process had bad luck by minimizing furnace charge.
Material pipe quantity is greater than one, preferably reaches more than 5, the discharging of material pipe can be made to be evenly distributed in stove, can improve the working of a furnace, shorten the heat, reduce alloy product specific energy consumption, improve efficiency of energy utilization and mineral hot furnace production efficiency, improve output.
