Portion is equipped with the support rod 88 for being fixedly connected on 2 top of furnace body, is fixedly connected between support plate 3 and connecting rod 89 and is looped around shunting
The elastic foldable film 9 of 82 outer ring of pipe.With the rotation of rotary table 31, the boiler tube 33 on the first station after the completion of sintering,
It takes out and replaces the boiler tube 33 in second station and be sintered, at this point, the boiler tube 33 of the first station needs to cool down, pass through isocon
82 carry out air blowing cooling, since the boiler tube 33 of each station is successively to leave sintering hole 21, there is the time difference between each other, right
33 cooling requirement of corresponding boiler tube is different, and when second station needs cooling, corresponding first station has cooled down a period of time
, therefore, cooling air-flow should be concentrated and feed to second station cooling, it can be seen that, pass through elastic foldable film 9 and air channel 87
Design, with the rotation of rotary table 31, air channel 87 clockwise is successively opened, and due to 87 mouthfuls of air channel
Diameter is sequentially reduced along clockwise direction, and then is adequately just effectively distributed cooling air-flow, and cooperation is poor cooling time, accomplishes to fill
Divide efficient cooling, cooling efficiency height, finally, the revolution of rotary table 31 is simultaneously after the cooling of whole boiler tubes 33 and replacing workpiece
Original state is come back to, just the sintering of next batch workpiece.
When in use, after corresponding boiler tube 33 is pushed into sintering hole 21 by telescopic cylinder 32, strut 47 is expressed on furnace body 2
It holds and jacks up the second sealing plate 45, at this point, taper sprue 48 is separated with the second through-hole 42, tracheae is connected to 33 inner cavity of boiler tube,
Pumping operation can be carried out, meanwhile, escape pipe 71 opens the first sealing plate 64, at this point, escape pipe 71 just connects with 33 inner cavity of boiler tube
It is logical, nitrogen is poured into boiler tube 33 by inflator pump 7 and is protected, the mode of lower end pumping is evacuated by upper end, so that boiler tube
Air is sufficiently discharged in 33, and nitrogen protection is abundant.
With the rotation of rotary table 31, the boiler tube 33 on the first station takes out after the completion of sintering and replaces second
Boiler tube 33 on station is heated, at this point, the boiler tube 33 of the first station needs to cool down, blow by isocon 82 cold
But, since the boiler tube 33 of each station is successively to leave sintering hole 21, there is the time difference between each other, to corresponding boiler tube 33
Cooling requirement is different, and when second station needs cooling, corresponding first station has cooled down a period of time, therefore, should
It is cooling that cooling air-flow concentration is fed into second station, it can be seen that, by the design of elastic foldable film 9 and air channel 87, with
The rotation of rotary table 31, air channel 87 clockwise are successively opened, and since 87 bore of air channel is along clockwise
Direction is sequentially reduced, and then is adequately just effectively distributed cooling air-flow, and cooperation is poor cooling time, is accomplished sufficiently efficient cold
But, cooling efficiency is high, finally, rotary table 31, which turns round, simultaneously to be come back to just after the cooling of whole boiler tubes 33 and replacing workpiece
Beginning state, the just sintering of next batch workpiece.
