Description
Technical field
The utility model relates to a kind of efficient energy-saving metal regeneration smelting system.
Background technology
The existing regenerated metal particularly regeneration smelting system of aluminium adopts many stoves integrated structure mostly, wherein using more is four stoves or five stove built-up types, many stoves are connected in some way, its outstanding feature is exactly the problem that has solved maintenance blowing out, has improved to a certain extent the utilization ratio of smelting furnace.But, the existing many stoves smelting system that comprises that smart group is box-like, because its unitized construction itself exists certain irrationality, blast furnace, aluminium bits stove and the division of labor separately of corresponding holding furnace are relatively more fixing, function singleness, and this has just determined that its whole smelting system combines the aspects such as the handiness of coordination, reasonableness, function and likes certain restriction.Particularly its each smelting furnace of existing smelting system is regardless of function, regardless of its job specification and task, its heating unit structure is set and all there is certain defect in each corresponding this body structure of heating unit, make system thermal waste larger, and then running cost is increased.
Utility model content
The purpose of this utility model is the deficiency existing for prior art, and a kind of efficient energy-saving metal regeneration smelting system is provided.This efficient energy-saving metal regeneration smelting system is simple and reasonable for structure, and working efficiency is high, energy consumption is low, and running cost is low, and operation combination is flexible, convenient, simple.
The technical scheme of the utility model efficient energy-saving metal regeneration smelting system comprises blast furnace, two aluminium bits stoves and two holding furnaces, described blast furnace, aluminium bits stove and holding furnace interconnect by a communicating valve, described two aluminium are considered to be worth doing between stoves, between two holding furnaces and aluminium is considered stove to be worth doing and between holding furnace, interconnects respectively by corresponding control valve accordingly, between described blast furnace and aluminium bits stove, be provided with gas phase closed tube, described blast furnace is provided with heat-storage type burner, and described holding furnace is respectively equipped with aluminium bits stove the thermophore being connected with the heat-storage type burner of described blast furnace.
In described holding furnace and the aluminium bits thermophore of stove and the heat-storage type burner of blast furnace, be respectively equipped with the heat exchange coil being mutually connected in series.
Described holding furnace is provided with permanent-magnet type mixer.
The utility model efficient energy-saving metal regeneration smelting system is with its distinctive many stoves combined connecting structure, can form intellectual one or more groups built-up type smelting system or a melting ingot casting system, and there is more fully composition and adjust room and time, particularly its blast furnace, aluminium are considered the Rational structure of the heating unit of stove and holding furnace to be worth doing, have fundamentally improved operational efficiency and the energy-saving effect of smelting system.
Accompanying drawing explanation
Fig. 1 is the utility model efficient energy-saving metal regeneration smelting system structural representation.
Embodiment
Now by embodiment, the utility model is described in further detail by reference to the accompanying drawings, as shown in Figure 1, efficient energy-saving metal regeneration smelting system is considered stove 2 and holding furnace 3 each Liang Tai and a blast furnace 1 to be worth doing by aluminium and is formed, and each holding furnace 3, aluminium bits stove 2 and blast furnace 1 interconnect by the communicating valve 8 of a multi-channel type.Meanwhile, two aluminium are considered to be worth doing between stoves 2 and by corresponding control valve 10, interconnect respectively between two holding furnaces 3, and by control valve 10, interconnect between holding furnace 3 and corresponding aluminium bits stove 2.Between blast furnace 1 and two aluminium bits stove 2, by gas phase closed tube 7 its tops (gas phase), interconnect, with pressure and/or the temperature between balance blast furnace 1 and two aluminium bits stove 2.In the furnace chamber of holding furnace 3, be provided with permanent-magnet type mixer 9 simple in structure, to be easy to control, by permanent-magnet type mixer 9, can make the aluminium liquid uniform ingredients of holding furnace 3, to improve ingot quality.
Blast furnace 1 is provided with heat-storage type burner 6, and then makes blast furnace 1 form the smelting furnace of an active heating-type.Aluminium bits stove 2 and holding furnace 3 are respectively equipped with thermophore 4, and aluminium bits stove 2 and holding furnace 3 form passive type smelting furnaces by thermophore 4 respectively, and each thermophore 4 of holding furnace 3 and aluminium bits stove 2 is accepted the waste heat that heat-storage type burner 6 and/or smelting system provide.Between aluminium bits stove 2 and the thermophore 4 of holding furnace 3 and the heat-storage type burner 6 of blast furnace 1, by corresponding medium channel, interconnect respectively; Meanwhile, the thermophore 4 of aluminium bits stove 2 and holding furnace 3 can be connected with the bootstrap system (as the heat recovery system of ingot casting device) of smelting system simultaneously.
The thermophore 4 of aluminium bits stove 2 and holding furnace 3 is respectively equipped with corresponding heat exchange coil 5, a wherein port of the two-port after each heat exchange coil 5 is connected in series is mutually connected with the smoke outlet of heat-storage type burner 6, another port is connected with the smoke exhaust pipe 11 of smelting system, the flue gas that heat-storage type burner 6 smoke outlets are discharged after thermophore 4 heat exchange through aluminium bits stove 2 and holding furnace 3 by the outer row of smoke exhaust pipe 11 of smelting system.
