Description of drawings
Fig. 1 is a structure chart of the present utility model.
Fig. 2 is an application example figure of the present utility model.
The specific embodiment
Ask for an interview Fig. 1, the below sidepiece of the cylindrical shell 23 of stainless steel extends to be useful on introduces interface 231 with running water or frozen water as the medium of cooling medium, introducing interface 231 by this medium just can be incorporated into frozen water or running water in the chamber, tube seals by the upper and lower of chamber, after medium introducing interface 231 is introduced cooling medium, just draw interface 232 and draw, constitute and reflux by medium.The below of cylindrical shell 23 is a funnelform cylinder base 234, the bottom center of cylinder base 234 is narrow to have shortened the interface 235 of giving vent to anger into, the interface 235 of giving vent to anger is connected with circulating fan 1 by pipeline 4 by a by-pass connection 2353, give vent to anger and set up liquid level gauge 2352 on the interface 235, discharging valve 2351 continues below the interface 235 of giving vent to anger.At ordinary times, discharging valve 2351 cuts out, yet the steam productive set as soon as give vent to anger in the interface 235 is opened discharging valve 2351 according to the demonstration of liquid level gauge 2352 when covering or approaching the inlet of by-pass connection 2353, and the steam of institute's productive set in interface 235 cavity of resorptions of giving vent to anger is got rid of.
One group of quantity has up to a hundred pipes at least and the protective gas condenser pipe 22 that assembles is arranged in the tube chamber of cylindrical shell 23; every protective gas condenser pipe 22 is very very thin; so that it can embody function capillaceous; the pipe lower end port of protective gas condenser pipe 22 communicates with the interface 235 of giving vent to anger, and the pipe upper end is stretched out one section in cylindrical shell 23 and fixing with web 221.The lower end and web 221 sealing and fixing of shunting cover 21, the upper end is close solid by seal cover 211, and the mantle cavity 212 of shunting cover 21 communicates with the air inlet 222 of protective gas condenser pipe 22.When the side is connected to after high temperature protection gas that air inlet pipe interface 231 on the shunting cover 21 will come from burner hearth is incorporated in the shunting cover 21; protective gas promptly enters the tube chamber of protective gas condenser pipe 22 from air inlet 221; enter the interface 235 of giving vent to anger after the cooling of the cooling medium in cylindrical shell 23 (frozen water or running water), and then under the effect of circulating fan 1, send burner hearth back to by by-pass connection 2353.The fixedly ear 236 that is arranged on cylindrical shell 23 nearly middle parts is for installing and fixing usefulness.
Please continue to see Fig. 1 and in conjunction with Fig. 2, the applicant narrates operation principle of the present utility model.By Fig. 2 finding, circulating fan 1 of the present utility model is that burner hearth connects by the body of heater 6 of pipeline 5 and bell jar stove, and in like manner, air inlet pipe interface 231 is connected by pipeline 3 and body of heater 6.When after the bell jar stove has been finished sintering to electronic product, needing the cool electronic product, so start cycles blower fan 1 and starting continue medium introduce on the pipeline of interface 231 pump and to body of heater 6 in feeding as the nitrogen of protective gas.At this moment; under the effect of circulating fan 1; make the high-temperature gas in the body of heater 6 enter body of heater 6 again through air inlet pipe interface 231, shunting cover 21, air inlet 222, the tube chamber of protective gas condenser pipe 22, the interface 235 of giving vent to anger, by-pass connection 2353, circulating fan 1 in regular turn, form the process of circulating reflux from pipeline 3.Meanwhile; introduce running water or the frozen water that interface 231 is incorporated in the tube chamber of cylindrical shell 23 by medium and in the circulating reflux process, protective gas condenser pipe 22 is cooled off, previous about about 1000 ℃ high-temperature gas is being reduced to about 60 ℃ through temperature after the cooling of about 4-6h.In whole process, obtained recyclingly as the nitrogen of protective gas, neither cause waste, can not bring ambient influnence because of effluxing yet.
When discharging as required and to the accumulation thing in the cylindrical shell 23, then can carry on a shoulder pole retaining by standby discharging interface 233; When the hypomere of the interface 235 of giving vent to anger or when claiming the moisture content of below productive set to increase, then can get rid of by opening discharging valve 2351.
