Specifically, insulating layer 110 provided in this embodiment is made of heat-preservation cotton, and is also enclosed in heat-preservation cotton outer layer
One layer of aluminium skin.It should be noted is that the package of aluminium skin is on the one hand to carry out limited support, in addition a side to heat-preservation cotton
Face makes it more resistant to corrosion, to extend exhaust gas bleeder also for protection exhaust gas bleeder road 120 and main pipeline 140
The service life in road 120 and main pipeline 140.
It is emphasized that in other embodiments, it is not limited in above structure insulating layer provided in this embodiment
110, the thermal insulation material that other structures material is constituted is can also be, as long as heat preservation and Corrosion Protection can be reached.
The present embodiment also provides a kind of system 10 for inhibiting annealing kiln to fall object comprising above-mentioned inhibition annealing kiln is fallen
The device 100 of object, annealing kiln system 12 and provide the supply unit of mains power for the device 100 for inhibiting annealing kiln to fall object
14。
It should be noted that supply unit 14 falls the exhaust gas discharge suction unit of the device 100 of object with inhibition annealing kiln
130 are electrically connected, and cooling duct and the inhibition annealing kiln of kiln system 12 of annealing fall each exhaust gas discharge branch of the device 100 of object
Pipeline 120 is connected to, and therefore, has the advantages that above-mentioned inhibition annealing kiln falls the every of the device 100 of object.
Incorporated by reference to referring to FIG. 1, FIG. 2 and FIG. 3, the work of the system 10 provided in this embodiment for inhibiting annealing kiln to fall object is former
Reason is：
Exhaust gas is discharged in each exhaust gas bleeder road 120 by the cooling duct for the system 10 that inhibition annealing kiln falls object
Portion, then under the swabbing action that exhaust gas discharges suction unit 130, to which exhaust gas bleeder road 120 enters main pipeline 140
It is interior, and be finally discharged.
It should be noted that since the device 100 that inhibition annealing kiln provided in this embodiment falls object is set in main pipeline 140
Set exhaust gas discharge suction unit 130 (wind turbine 132) so that inhibit the system 10 that annealing kiln falls object that will can timely and effectively move back
The waste gas exhaust in the fiery each area in kiln top surface goes out, and to effectively inhibit the generation for pouring in down a chimney phenomenon, avoids the vibrations of cooling duct, prevents
Stop falling for cooling duct foreign matter, ensure that the quality of glass plate process.Therefore, inhibition annealing provided in this embodiment
Kiln falls the device 100 of object and annealing kiln is inhibited to fall the system 10 of object, can improve the quality of production of 3D glass processings, for public affairs
Department creates value, has higher application value.
Second embodiment
Fig. 4 is please referred to, the present embodiment provides the devices 200 that a kind of inhibition annealing kiln falls object, are carried with first embodiment
The device 100 that the inhibition annealing kiln of confession falls object is roughly the same, the difference is that, inhibition annealing kiln provided in this embodiment falls
The air outlet 241 of the main pipeline 240 of the device 200 of junk is in the different of first embodiment.
Specifically, it is provided with gas control valve 242 at the air outlet 241 of main pipeline 240 provided in this embodiment.It needs
It is bright, by gas control valve 242, it is not only able to effectively be precisely controlled the emission flow of exhaust gas in main pipeline 240, and
Ambient pressure can be reduced for air pressure in its main pipeline 240 by turning outlet speed down when extraneous air pressure change is larger
Influence so that inhibit annealing kiln fall the device 200 of object for preventing annealing kiln from falling the better of foreign matter.
Further, bidirectional modulation valve is preferably used as gas control valve 242 in the present embodiment.It needs to illustrate
It is that bidirectional modulation valve can be to the inside and outside carry out bidirectional bearing of main pipeline 240, therefore, the gas as the present embodiment introduction
Body regulating valve 242 has superior effect.
It is emphasized that in other embodiments, it is not limited in above-mentioned Bidirectional adjusting valve provided in this embodiment
This is a kind of for door, can also be other types of gas control valve 242.
3rd embodiment
Fig. 5 is please referred to, the present embodiment provides the devices 300 that a kind of inhibition annealing kiln falls object, are carried with second embodiment
The device 200 that the inhibition annealing kiln of confession falls object is roughly the same, the difference is that, inhibition annealing kiln provided in this embodiment falls
The wind turbine 332 of the device 300 of junk is different with first embodiment.
Specifically, wind turbine 332 provided in this embodiment is by two three-phase unusual fluctuation electric motor operations.It needs to illustrate
It is that the work of two three-phase unusual fluctuation machines can ensure the power stability output of wind turbine 332, while also can effectively share separate unit three
Work load when phase unusual fluctuation electric motor operation, making it, the service life is longer, reduces its rate of breakdown.
In conclusion the inhibition annealing kiln that the utility model embodiment provides falls the device of object by being arranged in main pipeline
Exhaust gas discharges suction unit so that the system that inhibition annealing kiln falls object can be timely and effectively by the useless of each area in annealing kiln top surface
Gas pumps out, and to effectively inhibit to pour in down a chimney the generation of phenomenon, avoids the vibrations of cooling duct, it is therefore prevented that cooling duct foreign matter
It falls, ensure that the quality of glass plate process；Match by the way that gas control valve is arranged, and with exhaust gas discharge suction unit
It closes so that inhibit the device that annealing kiln falls object that the effect of cooling duct vibrations is inhibited to further strengthen.Therefore, the utility model
The inhibition annealing kiln that embodiment provides falls the device and its system of object, exhaust gas can be excluded workshop by the draft of wind turbine
Outside, influence of the climate change (such as strong wind weather) for air pressure in main pipeline is prevented, the formation for pouring in down a chimney phenomenon is avoided, to subtract
The fluctuation of few annealing kiln temperature, finally improves the quality of production of 3D glass processings, and higher value is created for company, therefore its
With important application value.
The above descriptions are merely preferred embodiments of the present invention, is not intended to limit the utility model, for this
For the technical staff in field, various modifications and changes may be made to the present invention.It is all in the spirit and principles of the utility model
Within, any modification, equivalent replacement, improvement and so on should be included within the scope of protection of this utility model.
