Abstract
The invention discloses an energy-saving top charge hot-air-drying device for a submerged arc furnace. The device comprises a central bin (4), wherein one end of a 1# belt (1) is connected to a distribution station, the other end is connected with an inlet end of a fork hopper (2), an outlet end of the fork hopper (2) is connected with a 2# belt (3) connected with a feed end of the central bin (4), and a bottom discharge end of the central bin (4) is connected with a material pipe (5). The problems that moisture carried by raw materials directly entering the furnace can take away a lot of heat during vaporization, dust sticks to a bag of a dry dust collector easily, and though a traditional furnace material drying system can transfer the link of decomposition of O2 with high-valence manganese oxides to the outside, the system occupies a large area, is high in investment, cannot realize hot material entrance, causes energy waste and the like in the prior art are solved.

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.
Summary of the invention
The technical problem to be solved in the present invention: 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 solution of the present invention:
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.
Beneficial effect of the present invention:
Owing to have employed technique scheme, compared with prior art, the present invention 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 present invention, 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 present invention 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, shortens the heat, and reduces alloy product specific energy consumption, improves efficiency of energy utilization and mineral hot furnace production efficiency, improves 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.
Accompanying drawing explanation
