Respectively by being arranged on Yao Ding tops low temperature hot blast air draft pipe and being arranged on kiln bottom bottom low temperature hot blast air draft pipe with setting
Low temperature hot blast windlass main in kiln body side is connected；Last unit in the higher temperatures cooling zone adjacent with sub-cooled area
Section top is arranged side by side four upper blowpipes, bottoms and shifts to install four lower blowpipes, respectively by being arranged on kiln top
Portion's low temperature hot blast air supply duct and it is arranged on and kiln bottom bottom low temperature hot blast air supply duct and is arranged on the low temperature hot blast of kiln body side
Header pipe is connected；In the side of kiln body, blower fan is set, its air outlet is connected with low temperature hot blast header pipe, its suction opeing with it is low
Warm wind windlass main is connected.The hot blast in sub-cooled area is extracted out by blower fan, adjacent high-temperature cooling zone burner hearth is sent into, utilizes
Product is cooled down with the temperature difference in High-temperature cooling area.So in the unit section of high-temperature region first（Along the line of production）It is again provided with exhausting
Mouthful, its hot blast is extracted out by blower fan, is sent into cooling product in area's at higher temperature, so circulation.
The beneficial effects of the utility model are：Due to whole cooling section is divided into several different temperatures cooling zones, each
Temperature cooling zone is made up of several unit sections, and along the product direction of motion, the temperature of each warm area reduces step by step, is taken out by blower fan
The hot blast in sub-cooled area is sent into adjacent high-temperature cooling zone, and the hot blast for having the temperature difference with product directly purges product, makes full use of kiln
Itself interior waste heat cools down to product, so that product uniform decrease in temperature.With rational in infrastructure, easy to make, good cooling results,
The advantages that saving energy consumption, effectively solve cold wind and directly purge the problems such as glass tape influences product quality, so that product quality obtains
To increasing substantially.
The utility model is described in further detail below in conjunction with the accompanying drawings.
Brief description of the drawings：
Fig. 1 is the utility model sub-cooled area suction opeing schematic cross-section；
Fig. 2 is the utility model adjacent high-temperature cooling zone air outlet schematic cross-section；
Fig. 3 is the utility model cooling section local overlooking structural representation.
In figure：1 is low temperature hot blast header pipe, and 2 be low temperature hot blast windlass main, and 3 be bottom low temperature hot blast air draft pipe,
4 be top low temperature hot blast air draft pipe, and 5 be upper exhausting branch pipe, and 6 be lower exhausting branch pipe, and 7 be blower fan, and 8 be that top low temperature hot blast is sent
Wind pipeline, 9 be bottom low temperature hot blast air supply duct, and 10 be upper blowpipe, and 11 be lower blowpipe.
Embodiment：
As shown in Figure 1, Figure 2, Figure 3 shows, float glass process devitrified glass annealing furnace hot air cooling back installation is to draw whole cooling section
It is divided into multiple different temperatures cooling zones, each warm area is made up of some unit sections, and each warm area has temperature gradient, is transported along product
Line direction cools down, it is characterised in that：Be arranged side by side at the top of the first module section compared with low temperature cooling zone exhausting branch pipe 5 on four,
Bottom shifts to install four lower exhausting branch pipes 6, respectively by being arranged on Yao Ding tops low temperature hot blast air draft pipe 4 and being arranged on kiln
Bottom low temperature hot blast air draft pipe 3 is connected with being arranged on the low temperature hot blast windlass main 2 of kiln body side；With sub-cooled area
Four upper blowpipes 10, bottoms are arranged side by side at the top of last unit section of adjacent higher temperatures cooling zone and shift to install four
Lower blowpipe 11, respectively by being arranged on Yao Ding tops low temperature hot blast air supply duct 8 and being arranged on kiln bottom bottom low temperature hot blast
