Background technology
Float glass lehr is that the glass tape of shaping is annealed in process of production, eliminates the big of glass internal stress
Type Thermal Equipment, it is to influence glass annealing quality and the key equipment of performance.Cool down the main medium that wind is glass annealing, float glass process
The annealing process of plate glass be exactly by 600 DEG C or so of high temp glass in annealing kiln according to glass annealing process requirement by
Gradually be down to the process of 70 DEG C or so of low temperature glass, this process be mainly by blower fan and Valve controlling cool down wind pressure and
The size of flow, glass is set to be cooled in annealing kiln by certain amplitude and speed.It is (also referred to as vertical along glass direction of advance
To) according to the 26S Proteasome Structure and Function of lear each several part it is divided into enclosed area, Re t areas and unlimited area.Annealed according to glass
Technological requirement, enclosed area are divided into A areas, B areas, C areas again;Unlimited area is divided into D areas, F areas.Enclosed area is glass annealing drop
The main region of temperature, glass annealing quality and performance mainly determine by enclosed area, is the most region of glass cooling, glass
Annealing cooling rely primarily on cooling wind and realize, the heat that the cooling wind of enclosed area absorbs in the glass annealing process is more, temperature
Degree is high;The cooling wind of enclosed area makes its own expanded by heating, from room temperature while glass annealing cooling is made by heat exchange
(about 40 DEG C) change into the high-temperature gas (300-550 DEG C) of hundreds of degree, and the High-temperature cooling wind of hundreds of degree is transported in the airduct of closure
The outdoor exhaust duct discharge in Hang Bingcongge areas.
Temperature highest when float glass enters annealing kiln A areas, heat are being moved back by being transmitted to hull outside inside annealing kiln
When fiery kiln internal heat reaches balance, roller both sides are because enclosure interior temperature and external temperature difference are larger, therefore shrinking away from theshell body sidewall
Nearer, glass tape heat-energy losses are bigger, and consequence is to cause that glass tape edge temperature is low, and edge temperature adds with the center section temperature difference
Greatly.
Utility model content
In order to solve the above technical problems, the purpose of this utility model is to provide a kind of float glass annealing kiln edge
Heat riser.
The utility model adopts the following technical scheme that to complete above-mentioned purpose：
A kind of float glass annealing kiln edge heat riser, described annealing kiln edge heat riser, which has, to be set
Airduct in annealing kiln；Described airduct is two groups in annealing kiln between glass tape both ends and annealing kiln side wall；Often
Group is setting up and down two；Airduct described in every group two is located above and below glass tape；Described airduct, which stretches out, to move back
Fiery kiln is connected by three-way pipe with the indoor fan outside annealing kiln；Described indoor fan is with being arranged on glass tape
Portion, the top cooler of bottom are connected with bottom cooler, the gas in the top cooler and bottom cooler of extraction；Institute
The top cooler stated connects the outdoor fan being arranged on outside annealing kiln, the cooling wind that outdoor fan is extracted with bottom cooler
By top cooler, bottom cooler to the upper and lower surface of annealing kiln and glass tape carry out uniformly cool after make itself by
Thermal expansion, and the gas after will heat up by indoor fan is heated by airduct to glass tape both ends.
One end of described three-way pipe is connected with described indoor fan, and the other end is connected with outdoor discharge pipe, the
Three ends connect described airduct by butterfly valve open in usual.
The utility model proposes a kind of float glass annealing kiln edge heat riser, using above-mentioned technical side
Case, glass tape edge and the middle temperature difference in annealing kiln are reduced, utilizes the waste heat of gas in lear intercooler, section
About energy consumption, reduce thermal pollution；The device improves annealing kiln edge glass temperature, transverse temperature difference is reduced, so that caused by glass
Internal stress does not influence yield rate, effective control to glass tape transverse temperature difference, hence it is evident that improve the yield rate of glass；The device
Using the electrical load that can reduce glass tape upper and lower part heater, it can not be opened when using the device or small guide vane makes
With glass tape upper and lower part heater；The device can effectively block the heat transfer inside annealing kiln and outside annealing kiln,
Play a part of heat bridge, ensure that glass tape edge and centre, surface and central temperature reach unanimity, be advantageous to the annealing of glass.
