Description
Technical field
The utility model belongs to smelting non-ferrous metal equipment, particularly a kind of aluminium alloy smelting saving furnace.
Background technology
Melting cast aluminum alloy equipment is mainly take electric furnace class and Fuel Furnace class as main, and its thermal efficiency of resistance-type crucible furnace in the electric furnace class is low, burn-off rate is slow, and cost is high again.Although frequently the induction furnace burn-off rate is fast for the electricity in the electric furnace class, aluminium alloy is subject to the stirring action homogeneous chemical composition of magnetic force, and is easily air-breathing and be involved in oxide inclusion, and operating cost is also high.The combustion-type crucible furnace thermal efficiency of Fuel Furnace class is low, cost is high, although and the preheating limit, tower reverberatory furnace furnace charge limit of Fuel Furnace class is toward the trailing edge fusing, the thermal efficiency is high, burn-off rate is fast, but can only the melted alloy ingot, can not carry out the alloying component adjustment, moreover the equipment one-time investment is larger, is difficult to satisfy the process requirements of aluminium alloy casting melting.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned technical deficiency, provides a kind of simple in structure, and operation is convenient, can guarantee again the aluminium alloy smelting saving furnace that the aluminium water quality is good.
the technical scheme that the utility model technical solution problem adopts is: the aluminium alloy smelting saving furnace comprises body of heater, crucible, blower fan, three-way valve, hot air duct, the stove that is characterized in the body of heater upper end along on the crucible supporting plate is housed, crucible supporting plate pop-up dress crucible, be provided with burner hearth between crucible and body of heater, the body of heater lower right side is equipped with burner, burner nozzle is housed in burner, burner nozzle is placed on the position of corresponding crucible bottom outer rim tangent line, on the body of heater of burner top, the annular-heating plate is housed, annular-heating plate lower end connects pre-hot bellows, pre-hot bellows encloses and is contained in the upper of furnace body periphery, hot bellows is suitable for reading in advance is communicated with crucible is suitable for reading, above pre-hot bellows, stay-warm case is housed, pre-hot bellows connection hot air duct upper end, the hot air duct lower end is communicated with the upper end interface of three-way valve, the left end interface of three-way valve is communicated with burner nozzle, the right-hand member interface of three-way valve is gas inlet, pre-hot bellows right lower quadrant is communicated with blower fan.
The beneficial effects of the utility model are: the aluminium alloy smelting saving furnace is simple in structure, easy to use, can use the fuel such as kerosene, diesel oil, natural gas, liquefied petroleum gas, the thermal efficiency is high, good energy-conserving effect, solve aluminium water and produced secondary oxidation, an air-breathing difficult problem that causes the aluminium water quality to descend because of turnover, provide guarantee for producing the fine aluminum alloy-steel casting.
Description of drawings
Illustrate with embodiment below in conjunction with accompanying drawing.
Fig. 1 is that figure cuts open in the aluminium alloy smelting saving furnace structure office of overlooking.
The A-A cutaway view of Fig. 2 Fig. 1.
In figure, the 1-burner; The 1-1-burner nozzle; The 2-three-way valve; The 2-1-gas inlet; The pre-hot bellows of 3-; The 4-blower fan; The 5-crucible; The 6-burner hearth; The 7-hot air duct; 8-annular-heating plate; 9-crucible supporting plate; The 10-stay-warm case; The 11-body of heater.
The specific embodiment
Embodiment, with reference to accompanying drawing 1,2, the stove of body of heater 11 upper ends of aluminium alloy smelting saving furnace along on crucible supporting plate 9 is housed, support crucible 5 on crucible supporting plate 9 is provided with burner hearth 6 between crucible 5 and body of heater 11.Body of heater 11 lower right side are equipped with burner 1, the in-built burner nozzle 1-1 of burner 1, burner nozzle 1-1 is placed on the position of corresponding crucible 5 bottom outer rim tangent lines, on the body of heater 11 of burner 1 top, annular-heating plate 8 is housed, annular-heating plate 8 lower ends connect pre-hot bellows 3, and pre-hot bellows 3 encloses that to be contained in body of heater 11 tops peripheral.Hot bellows 3 is suitable for reading in advance is communicated with crucible 5 is suitable for reading, above pre-hot bellows 3, stay-warm case 10 is housed, pre-hot bellows 3 is communicated with hot air duct 7 upper ends, hot air duct 7 lower ends are communicated with the upper end interface of three-way valve 2, the left end interface of three-way valve 2 connects burner nozzle 1-1, the right-hand member interface of three-way valve 2 is gas inlet 2-1, and pre-hot bellows 3 right lower quadrants are communicated with blower fan 4.
The using method of aluminium alloy smelting saving furnace is: fuel enters three-way valve 2, burner nozzle 1-1 by gas inlet 2-1, light flame and enter 6 pairs of crucibles 5 of burner hearth and heat, and can regulate fuel feeding or air demand control combustion temperature by burner nozzle 1-1.The cold wind that produces by blower fan 4 obtains abundant preheating through pre-hot bellows 3, hot bellows 3 is suitable for reading in advance is communicated with and makes pre-hot bellows 3 obtain certain heat with crucible 5 is suitable for reading, annular-heating plate 8 directly is connected with burner hearth 6 can obtain abundant heat, and pre-hot bellows 3 becomes cold wind into warm-air supply burner 1.The crucible 5 that fills aluminium water in aluminum alloy smelting furnace can directly hang out from stove casts, and has reduced like this aluminium water turnover, solved aluminium water because of around produce secondary oxidation, an air-breathing difficult problem that causes the decline of aluminium water quality.
