Abstract
The utility model relates to a heated air circulation mechanism for continuous annealing furnace to solve the problems of the prior heated air dual circulation manner of annealing furnace including non-uniform work piece heating and relatively high cost. The heated air circulation mechanism comprises a blower with a volute chamber, an air inlet passage, and an air return passage, wherein the air comes out from one side of the volute chamber and enters the furnace cavity from the top of the furnace cavity through the air inlet passage, then enters the air return passage from the bottom of the furnace cavity after passing through the material in the furnace cavity, and then enters the inlet of the blower. In the single-direction laminar flow air circulation manner, air only comes out from one side of the blower and returns from the bottom of the blowers to form a heated air circulation. The heated air flows in the furnace in vertical and horizontal manner, which is helpful for uniformly heating the work piece with complex structure in the furnace. The utility model not only saves wind guiding material (about 1/3), but also remarkably improves the uniformity of the temperature in the furnace.
Description
Technical field
The utility model relates to continuous annealing furnace hot air circulation mechanism.
Background technology
Domestic existing continuous annealing furnace hot air circulation mode adopts two Recycle design mostly, and referring to Fig. 4, blower fan 1 is at roof of the furnace, spiral case 2 is to the two-way air-out in both sides, two circulation air paths 3,4 are arranged, so need there be the bidirectional guide device also will design specially, cost is higher.In addition, this pair of Recycle design, it is big to take up room, not energy-conservation, and heated parts is non-uniform temperature during complex-shaped workpieces especially.
Summary of the invention
What the utility model solved is exactly that the two Recycle design of existing annealing furnace hot blast are for inhomogeneous, the cost problem of higher of workpiece heating.
This continuous annealing furnace hot air circulation mechanism comprises the blower fan that has volute, air inlet duct, and air-return duct, the two ends of air inlet duct communicate with sidepiece, the roof of the furnace of volute respectively; One end of air-return duct communicates with burner hearth bottom, the other end communicates with the inlet of blower fan.Wind comes out from a side of volute, enters burner hearth through air inlet duct from roof of the furnace, enters air-return duct from this burner hearth bottom behind the material in this burner hearth of flowing through, and enters the population of blower fan again.
This unidirectional advection wind formula Recycle design only needs unidirectional air-out, promptly at blower fan one side air-out, from bottom return air, constitutes hot air circulation.Hot blast becomes to be level, perpendicular flow in stove, more help complex-shaped workpieces even heating in stove.Not only save wind-guiding material about 1/3, and can greatly improve the homogeneity of temperature in the stove.
As further improvement, above-mentioned continuous annealing furnace hot air circulation mechanism, described burner hearth bottom communicates with the bottom of another burner hearth, and an end of air-return duct communicates with the top of another burner hearth.After wind comes out from described burner hearth bottom, enter the bottom of another burner hearth again, enter air-return duct from another roof of the furnace behind the material in another burner hearth of flowing through.Adopt this advection wind formula structure, reduced the consumption of material, saved furnace inner space, make equipment inner structure compacter.
Continuous annealing furnace hot air circulation mechanism for above-mentioned is provided with the air quantity regulating mechanism in the air inlet duct.The air quantity regulating mechanism belongs to prior art, but as the adjustable plate of two relatively sliding that can be in air inlet duct, respectively has ventilation hole on these two adjustable plates; During two adjustable plate relatively sliding, can regulate the overlap ratio of ventilation hole on two adjustable plates, regulate air quantity with this.

Figure 22 is the right view of Figure 21.
Fig. 3 be among Fig. 1 volute overlook enlarged view (rotation).
Fig. 4 is the existing chamber structure that continuous annealing furnace is arranged.
Embodiment
Among Fig. 1, continuous annealing furnace hot air circulation mechanism, comprise the blower fan 6 that has volute 5, wind comes out from a side of volute (referring to Fig. 3), enter burner hearth 8 through air inlet duct 7 from roof of the furnace, enter the bottom of burner hearth 9 in the burner hearth 8 of flowing through behind the material from burner hearth 8 bottoms again, enter air-return duct 10 from burner hearth 9 tops behind the material in the burner hearth 9 of flowing through, enter the population of blower fan 6 again, finish a circulation.
Referring to Figure 21,21, be provided with the air quantity regulating mechanism in the air inlet duct, but the i.e. adjustable plate 11,12 of two relatively sliding respectively has ventilation hole 13 on these two adjustable plates; During two adjustable plate relatively sliding, can regulate the overlap ratio of ventilation hole 13 on two adjustable plates, regulate air quantity with this.
Adopt this advection wind formula structure, reduced the consumption of material, saved furnace inner space, make equipment inner structure compacter, make that to be heated workpiece each several part temperature even.
