Description
Technical field
The present invention relates to heating furnace, particularly to a kind of be applied to energy-efficient aluminium bar mixing in Aluminum extrusion technique plus
Hot stove.
Background technology
At present, the many rod stoves occurring in market are mainly heated to the air in burner hearth by burner, using heat
Gas heats to many aluminium bars side by side.How there is preheating time length it is impossible to realize the defect of gradient-heated in excellent stove.Single rod
Stove using structure be single aluminium bar to be carried out individually by way of directly flame heating by the spray gun of body of heater both sides.Although single rod
Stove can shorten the pre-warmed time, but the high-temperature flue gas producing in heating process can be exhausted directly to outside body of heater, causes heat energy
Waste.
Content of the invention
In view of the above problems, it is an object of the invention to provide a kind of save energy consumption, heat loss is little, preheating time is short,
To the efficiency of heating surface height of aluminium bar, it is used in daily maintenance and maintenance, and can be to the energy-efficient aluminium bar of aluminium bar gradient-heated
Hybrid Heating stove.
For achieving the above object, a kind of energy-efficient aluminium bar Hybrid Heating stove that the present invention provides, wherein, including single rod
Stove, and the many rod stoves with single rod stove one.Single rod stove includes the first body of heater and the thermal treatment zone being provided with the first body of heater, and
One body of heater is respectively equipped with the spray gun of the single aluminium bar of heating up and down.How excellent stove includes being provided with and the first body of heater one in the first body of heater side
The second body of heater, and be provided with the preheating zone communicating with the thermal treatment zone in the second body of heater.It is provided with first body of heater and the second body of heater
The connection thermal treatment zone and the body of preheating zone, body is provided with pressure transducer.Thus, the Main Function of preheating zone is to utilize to add
The waste heat of hot-zone preheats to aluminium bars many in preheating zone.The process of preheating is lower further away from the aluminium bar temperature of the thermal treatment zone, more
Much higher, the trend that shape is gradually successively decreased near thermal treatment zone aluminium bar temperature, here it is preheat the working method successively decreased in excellent stove.
In some embodiments, it is provided with breach corresponding with aluminium bar diameter width between preheating zone and the thermal treatment zone.By
This, during use, aluminium bar just can pass through from the width of breach, and be less than the width knot of breach using the diameter width of aluminium bar
Structure, the thermal treatment zone and preheating zone are separated, and improve the efficiency of heating surface of single rod stove.
In some embodiments, it is provided between preheating zone and the thermal treatment zone and preheating zone and the thermal treatment zone are separated into two chambeies
The baffle plate of room.One of effect accordingly, for baffle plate is to separate the thermal treatment zone and preheating zone, improves the heating effect of single rod stove
Rate.
In some embodiments, the second body of heater is provided with the exhaustor of connection preheating zone.Thus, the effect of exhaustor
It is that the gas after preheating in preheating zone is discharged.
In some embodiments, the first body of heater side is provided with the detachable gate opening heating furnace.Thus, it is possible to it is very square
Just the thermal treatment zone and preheating zone are overhauled and safeguarded.
In some embodiments, spray gun is respectively arranged at the both sides of aluminium bar, and spray gun is the spray gun of scalable flame temperature.
Thus, the set location of spray gun can be also the both sides up and down in single rod stove in the left and right sides of single rod stove.Multiple spray guns can root
Adjust the temperature of flame according to aluminium bar different situations.Need to realize same aluminium bar have different temperature, that is, during gradient-heated, adjust
Heating-up temperature or the wherein several spray guns of closing.
In some embodiments, it is provided with heat exchanger between exhaustor and spray gun.
In some embodiments, heat exchanger is included the outer tube body being connected with exhaustor and connects supply with the body of spray gun
The interior tube body of combustion air.Thus, the effect of heat exchanger is to being supplied to using the waste heat entering in preheating zone in outer tube body
The combustion air of spray gun is preheated, and realizes the purpose of save energy further.
The invention has the beneficial effects as follows have saving that energy consumption, preheating time are short, high to the efficiency of heating surface of aluminium bar, be easy to day
Normal maintenance and maintenance, and can be to the effect of aluminium bar gradient-heated.First, the first body of heater and the second body of heater integrally connected, and
The thermal treatment zone is accordingly to connect with preheating zone.It is mainly characterized by single rod stove with how excellent stove is cleverly integrated in structure,
Remain all advantages and the performance of single rod stove.Using single rod stove heat area waste heat in advance to many rod stove preheating zones in aluminium bar
Heated, efficiently solve single rod stove smoke discharging residual heat cannot efficient recovery shortcoming, shorten the preheating time of many rod stoves,
The heat of loss 50%, reaches the purpose of energy-conserving and environment-protective less.In addition, having additional the pipe of the thermal treatment zone being interconnected and preheating zone
Pressure transducer on body, and body.The waste heat that the thermal treatment zone being in using the control of pressure transducer under heated condition is produced,
Be supplied to the aluminium bar in preheating zone to be preheated, can avoid because thermal treatment zone heating-up temperature too high, cause the waste of heat energy.Also
Have, between exhaustor and spray gun, be provided with heat exchanger, it is possible to use the waste heat entering in preheating zone helps to being supplied to spray gun
Combustion air is preheated, and plays combustion-supporting effect, further saves utilization and the heat loss of the energy.These measures are realized
Saving energy consumption and preheating time shorten feature, and to the efficiency of heating surface of aluminium bar very high.
Second, being provided with breach corresponding with aluminium bar diameter width between preheating zone and the thermal treatment zone or being provided with and will preheat
Area and the thermal treatment zone are separated into the baffle plate of two chambers, it is possible to use aluminium bar or baffle plate control remaining in single rod stove heat area well
The discharge of heat.The handling more flexible feature realized.
Third, being provided with, on the first body of heater side, the detachable gate that heating furnace can be opened, facilitate daily to single rod stove heat area
Overhauled and maintenance work with many rod stove preheating zones.
Fourth, spray gun is respectively arranged at the both sides of aluminium bar, spray gun is the spray gun of scalable flame temperature.Main purpose is to join
Close the extrusion equipment work of next procedure, such as, after aluminium bar enters extrusion equipment, extruding temperature in extrusion process, to aluminium bar
Degree needs to reach a certain constant temperature angle value, squeezes out aluminium section bar and is only optimal, the aluminium section bar otherwise squeezing out can not reach
Standard.Need to realize there are different temperature to same aluminium bar, i.e. gradient-heated.Adjust heating-up temperature or close wherein several
Spray gun is realizing the effect of gradient-heated.Such as, the spray gun near extrusion equipment heats required by aluminium bar temperature and extrusion equipment
Aluminium bar temperature corresponding, the spray gun heating aluminium bar temperature away from extrusion equipment is gradually successively decreased.I.e. extrusion equipment requires aluminium bar
Temperature be 500 DEG C, then near extrusion equipment spray gun heating aluminium bar temperature be 500 DEG C, the spray gun away from extrusion equipment adds
Hot aluminium bar temperature is 480 DEG C, 420 DEG C etc..So it is achieved that the effect of aluminium bar gradient-heated.Ensure that the extruding of next procedure
Steady temperature during equipment work.
