Blowing branch pipe 24d two ends.During work, cold wind enters upper horizontal air feed pipe 24a, and respectively by upper horizontal air feed pipe 24a
Longitudinal air feed pipe 24f on the air feed pipe 24b and second of longitudinal direction on the first of the upper transverse direction air feed pipe 24a both sides of portion's flow direction;Into first
Upper longitudinal air feed pipe 24b cold wind air feed branch pipe connection 24c along along first enters up-draught branch by up-draught branch pipe 24d one end
Pipe 24d;On into second longitudinal air feed pipe 24f hot blast along along second air feed branch pipe connection 24e by the another of up-draught branch pipe 24d
One end enters up-draught branch pipe 24d;Due to being uniformly drilled with multiple apertures on up-draught branch pipe 24d, can directly it be aligned by aperture
Quenching above product, and air feed can both ensure that air quantity is sufficient, can also ensure that each hole is blown simultaneously on up-draught branch pipe 24d both sides
The air quantity that goes out, blast are uniform, reduce chilling area top section temperature difference.
The lower air feed pipe group 25 includes lower horizontal air feed pipe 25c, is divided into the of the lower horizontal air feed pipe 25c both sides
The longitudinal air feed pipe 25d of longitudinal direction air feed pipe 25b and second time once, multiple the on described first time longitudinal direction air feed pipe 25b
Once air feed branch pipe connection 25a and multiple second time air feed branch pipe connections on described second time longitudinal air feed pipe 25d
25e, first time air feed branch pipe connection 25a and second time air feed branch pipe connection 25e are connected to lower blowing by flexible pipe respectively
Branch pipe 25f two ends.During work, cold wind enters lower horizontal air feed pipe 25c, and is flowed respectively by lower horizontal air feed pipe 25c middle part
First time longitudinal direction air feed pipe 25b of downward transverse direction air feed pipe 25c both sides and second time longitudinal air feed pipe 25d;It is vertical into first time
Lower blowing branch pipe is entered by lower blowing branch pipe 25f one end to air feed pipe 25b hot blast along first time air feed branch pipe connection 25a
25f;Into second time longitudinal air feed pipe 25d cold wind along second time air feed branch pipe connection 25e by the another of lower blowing branch pipe 25f
End enters lower blowing branch pipe 25f;Due to being uniformly drilled with multiple apertures on lower blowing branch pipe 25f, production can be directly directed at by aperture
Quenching below product, and air feed can both ensure that air quantity was sufficient simultaneously on lower blowing branch pipe 25f both sides, can also ensure each hole blowout
Air quantity, blast it is uniform, reduce the chilling area lower section temperature difference.
From the foregoing, it will be observed that the utility model forms the pipeline structure for reclaiming hot blast by efficient continuous, relay mode, will be each
Cooling heat during stage cooling ceramics is all recycled, and significantly reduces the dry, burnup of sintering process;Meanwhile, this reality
Without high warm air air is discharged into new, is effectively reduced thermal source pollution on the environment, product quality can be improved again.
Specifically, the hot blast of uniform temperature is produced after tail cold-zone cooling product(100 DEG C or so), the hot blast is by taking out hot blast
Machine 39 is extracted out and is sent in slow cooling area heat exchange manifolds;In slow cooling area(Temperature in slow cooling area is between 400 DEG C~600 DEG C), heat
Wind postpone cold-zone heat exchange manifolds one end feed the other end extract out, in transmitting procedure, the heat in slow cooling area postpone cold-zone heat
The tube wall for exchanging branch pipe is passed in pipe, raises the hot blast temperature in slow cooling area heat exchange manifolds pipe(Hot blast temperature can be more than 250
℃), and extracted out through heat-exchange fan 36;Heat-exchange fan 36 is extracted out after hot blast, and a part of hot blast is sent to drier and dries base
Body, reduces and dries burnup, and another part hot blast is delivered to combustion fan 14 after being filtered through filter;The hot blast that combustion fan 14 is exported
In chilling area(Temperature is more than 600 DEG C in chilling area)After chilling area heat exchange manifolds 20g again heat temperature raising(Maximum temperature
Up to 350 DEG C)The burner 23 of kiln is sent to, realizes combustion-supporting, combustion-supporting air temperature is further improved, can substantially reduce and burn till combustion
Consumption.Therefore, in total, the hot blast that the outlet of air-heater 39 is taken out in tail cold-zone heats remittance by Duo Gen slow cooling area heat exchange manifolds
The General Logistics Department is connected with the entrance of heat-exchange fan 36 in slow cooling area, and its outlet is connected with the entrance of combustion fan 14, this " to connect pushing belt
The relay air supply mode of drawing " can reduce the resistance in running, and reduction blower fan is born and power saving.Simultaneously as slow cooling area
Hot blast in heat exchange manifolds has tail cold-zone to pump, and is not contacted directly with product in slow cooling area heat exchange manifolds,
The type of cooling is gentle much compared with directly drying or being cooled down indirectly using normal temperature air, allows quartz at " 573 DEG C "
Crucial crystal formation transfer point slowly carry out(Because of Volume Changes drastically, temperature control is improper to produce stress cracking to this point), reduction
" wind is shied " defect, product yield is substantially improved, and improves Ceramics Enterprises benefit.
In addition, by intensive arrangement slow cooling area's heat exchange manifolds and chilling area heat exchange manifolds 20g in stove, between
The mode of heat exchange is connect, hot blast can be made not enter in stove, be conducive to pressure control, it is ensured that stove cooling is uniform, and the temperature difference is small, can prevent
Only because the temperature difference greatly caused by product cracking and deformation defect.Further, in order to reduce the section temperature difference in stove, according to kiln knot
Structure feature, slow cooling area heat exchange manifolds take longitudinal direction(It is parallel with the length direction of stove)The mode of intensive stringing, chilling area heat
Exchange branch pipe 20g and take transverse direction(It is parallel with stove section)The mode of intensive stringing, both can uniformly heat hot blast, also can be uniform
Product is cooled down, product cooling quality is ensure that while wind-warm syndrome is improved.
Correspondingly, in order to strengthen quenching effect, chilling area separately sets chilling blower fan 26, passes through the up-draught through both sides kiln wall
Branch pipe 24d and lower blowing branch pipe 25f, product quenching is directly directed in the upper and lower of product.In order to reach preferable sealing
Effect, in addition to segmenting branch pipe, main air-valve takes slide valve.
The above is preferred embodiment of the present utility model, it is noted that for the ordinary skill of the art
For personnel, on the premise of the utility model principle is not departed from, some improvements and modifications can also be made, these improve and moistened
Decorations are also considered as protection domain of the present utility model.
