Abstract
The utility model discloses a kind of preheating closure assemblies, wherein, it including the smoke exhaust pipe for connecting aluminum-bar heating furnace smoke outlet, the smoke exhaust fan being equipped on the end of smoke exhaust pipe, is equipped on smoke exhaust fan and extends to the waste heat recovery pipe of aluminum-bar heating furnace side aluminium bar input terminal, and be equipped with the cover body covered on the aluminium bar input terminal of aluminum-bar heating furnace side on waste heat recovery tube end.The utility model has waste heat recovery, and improves the effect of the pre- thermal efficiency of aluminium bar.
Description
Technical field
The utility model is related to a kind of preheating closure assemblies applied on aluminum-bar heating furnace.
Background technology
Currently, the aluminum-bar heating furnace occurred in market mainly heats the air in burner hearth by burner, it
Aluminium bar is heated using hot gas afterwards.Existing aluminum-bar heating furnace mainly ensures fully burning, heating process in burning
The high-temperature flue gas of middle generation can be exhausted directly to outside furnace body, and the waste heat of smoke evacuation still has 150 DEG C -400 DEG C can not be fully utilized, and causes
The waste of thermal energy.
Utility model content
In view of the above problems, the purpose of this utility model is to provide a kind of waste heat recoveries, and improve the pre- thermal efficiency of aluminium bar
Preheating closure assembly.
To achieve the above object, a kind of preheating closure assembly provided by the utility model, wherein including connecting aluminum-bar heating furnace
The smoke exhaust pipe of smoke outlet, the smoke exhaust fan being equipped on the end of smoke exhaust pipe, on smoke exhaust fan be equipped with extend to aluminium bar heating
The waste heat recovery pipe of stove side aluminium bar input terminal, and it is equipped on waste heat recovery tube end that cover in aluminum-bar heating furnace side aluminium bar defeated
Enter the cover body on end.Cover body includes the fixed seat being equipped on the aluminum-bar heating furnace of aluminium bar input terminal, be equipped in fixed seat with
Waste heat recovery pipe is connected to and the annular air guiding sleeve of internal diameter open type, and is equipped on annular air guiding sleeve and extends outwardly and avoid coordinating
Aluminium bar input terminal reduces the arc-shaped cover that cold wind is brought into.
In some embodiments, circular enclosure replacement can be used in arc-shaped cover.
In some embodiments, it is provided with heat exchanger on smoke exhaust pipe.
The utility model has the beneficial effects that tool waste heat recovery, and improve the effect of the pre- thermal efficiency of aluminium bar.Due to will be original
The waste heat flue gas of smoke exhaust pipe emptying is entirely used for aluminium bar preheating.Namely it is arranged in aluminum-bar heating furnace side aluminium bar input terminal a set of
Waste heat flue gas will be blown into the aluminium bar that aluminium bar input terminal is heated in annular air guiding sleeve by cover body, aluminium bar under smoke exhaust fan effect.Separately
Outside, arc-shaped cover or circular enclosure are outward extended on annular air guiding sleeve, such air inlet air duct lengthens, and cold blast rate is reduced, can be with
Improve preheating zone pre- heat utilization efficiency, this compared with prior art after, utilization rate of waste heat improves 10-15% after improvement, section
Energy 8-10% realizes waste heat recovery, and improves the effect of the pre- thermal efficiency of aluminium bar.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model application；
Fig. 2 is the structural schematic diagram of the utility model.
Specific implementation mode
Utility model is described in further detail below in conjunction with the accompanying drawings.
As shown in Figs. 1-2, a kind of preheating closure assembly, including connect the smoke exhaust pipe 2 of 1 smoke outlet of aluminum-bar heating furnace, discharging fume
Smoke exhaust fan 3 that the end of pipe 2 is equipped with is equipped on smoke exhaust fan 3 and extends to 1 side aluminium bar input terminal 4 of aluminum-bar heating furnace
Waste heat recovery pipe 6, and be equipped on 6 end of waste heat recovery pipe and cover in cover body on 1 side aluminium bar input terminal 4 of aluminum-bar heating furnace
7.Cover body 7 includes the fixed seat 71 being equipped on the aluminum-bar heating furnace 1 of aluminium bar input terminal 4, is equipped in fixed seat 71 and waste heat
Recovery tube 6 is connected to and the annular air guiding sleeve 72 of internal diameter open type, and is equipped on annular air guiding sleeve 72 and extends outwardly and avoid matching
It closes aluminium bar input terminal 4 and reduces the arc-shaped cover 73 that cold wind is brought into.Circular enclosure replacement can be used in arc-shaped cover 73.It is arranged on smoke exhaust pipe 6
There is heat exchanger 8.
In application, a set of cover body 7 is arranged in 1 side aluminium bar input terminal 4 of aluminum-bar heating furnace, aluminium bar 5 is acted in smoke exhaust fan 3
Under, waste heat flue gas will be blown into the aluminium bar 5 of heating aluminium bar input terminal 4 in annular air guiding sleeve 72.In addition, on annular air guiding sleeve 72 to
Outer to be extended with arc-shaped cover 73 or circular enclosure, such air inlet cold air duct lengthens, and cold blast rate is reduced, and can improve the pre- of preheating zone
Heat utilization efficiency, this compared with prior art after, utilization rate of waste heat improves the energy saving 8-10% of 10-15% after improvement.
Above-described is only some embodiments of the utility model.For those of ordinary skill in the art,
Without departing from the concept of the present invention, various modifications and improvements can be made, these belong to practical new
The protection domain of type.
