Abstract
The utility model belongs to a flue gas discharging chimney for a tower-type aluminum melting furnace. The flue gas discharging chimney is characterized in that a support wind box (1) is made to be round-shaped, an empty air passage (4) is disposed in the center of the support wind box (1), the support wind box (1) is fixed on the upper end of a flue steel plate (7), the inner side of the flue steel plate (7) is equipped with a flue insulating layer (10), the inner side of the flue insulating layer (10) is equipped with a flue thermal insulating layer (9), the inner side of the flue thermal insulating layer (9) is equipped with a refractory layer (8), the refractory layer (8) is internally provided with a flue gas passage (5), and an air inlet (2) is welded at the center of the left side of the support wind box (1) while a plurality of air outlets (3) are uniformly arranged at the right side of the support wind box (1). By using the flue gas discharging chimney provided by the utility model, waste heat of the flue gas is fully utilized, thereby saving energy; and the weight of the steel structure is also saved, with no need of utilizing an expensive refractory steel structure, thereby reducing costs of the chimney.
Description
Technical field
The utility model belongs to the parts of stove and accessory, particularly a kind of tower molten aluminium fire grate chimney.
Background technology
At present, small-sized aluminium melting and heat preservation stove generally all adopts tower molten aluminium machine, and material enters from the top exhaust opening, and the flue gas of rising plays the effect that adds thermal material.The smoke evacuation cylinder plays the smoke evacuation effect and works again to support the top enclosure.The smoke evacuation cylinder flue gas of tower molten aluminium stove is directly discharged, and not only fume afterheat does not take full advantage of, and it is higher to support top enclosure part steel construction temperature.In order to prevent thermal deformation, have to adopt heavier steel construction or adopt the heat resisting steel structure, wasted the energy, improved the cost of stove and accessory.
Summary of the invention
The object of the invention is to overcome above-mentioned technical deficiency, provide and utilize waste heat, save fuel, a kind of tower molten aluminium fire grate chimney reduced costs.
The technical scheme that the utility model technical solution problem adopts is: a kind of tower molten aluminium fire grate chimney, it is characterized in that supporting bellows and make circle, the center of supporting bellows is provided with sky wind passage, support the upper end that bellows are fixed on the flue steel plate, the flue layer is equipped with in the inboard of flue steel plate, the flue thermal insulation layer is equipped with in the inboard of flue layer, and the flue flame retardant coating is equipped with in the inboard of flue thermal insulation layer, in the flue flame retardant coating, is provided with exhaust gases passes; Support an air inlet of center, left side welding of bellows, right side is provided with a plurality of air outlets uniformly.
The beneficial effects of the utility model are: this utility model can be utilized fume afterheat fully, has saved the energy; Save the weight of steel construction, need not select valuable heat resisting steel structure, reduced the cost of chimney.
The accompanying drawing explanation
Below in conjunction with accompanying drawing, with embodiment, illustrate.
Fig. 1 is a kind of front view of tower molten aluminium machine smoke evacuation cylinder;
Fig. 2 is the A-A cutaway view of Fig. 1.
In figure: 1-supports bellows; The 2-air inlet; The 3-air outlet; The empty wind passage of 4-; The 5-exhaust gases passes; The 6-adpting flange; 7-flue steel plate; 8-flue flame retardant coating; 9-flue thermal insulation layer; 10-flue layer.
The specific embodiment
Embodiment, with reference to accompanying drawing, a kind of tower molten aluminium fire grate chimney, it is characterized in that supporting bellows 1 and make circle, the center of supporting bellows 1 is provided with sky wind passage 4, supports the upper end that bellows 1 are fixed on flue steel plate 7, flue layer 10 is equipped with in the inboard of flue steel plate 7, flue thermal insulation layer 9 is equipped with in the inboard of flue layer 10, and flue flame retardant coating 8 is equipped with in the inboard of flue thermal insulation layer 9, is provided with exhaust gases passes 5 in flue flame retardant coating 8; Support an air inlet 2 of center, left side welding of bellows 1, left side is provided with three air outlets 3 uniformly.Adpting flange 6 of welding on support bellows 1, for connecting the top enclosure.Support the inboard of bellows 1 directly to contact with flue flame retardant coating 8, can utilize like this waste heat in exhaust gases passes 5 that air is better heated, hot-air is discharged for burner from air outlet 3, or discharges the heat supply heating; The quantity of air outlet 3 is determined according to the quantity of burner.Exhaust gases passes 5 and air duct 4, make circle.
