Exhaust gas oil bath processing unit in the present invention be arranged to inside and outside structure, silicone oil, outer tube are placed in the outer tube 21
21 and inner tube 22 connected by communicating pipe 24, at least have the advantages that：
1. inner tube 22 is introduced into along air inlet from the exhaust gas mixed gas of sintering furnace discharge, after inner tube 22 is full of, along
Enter communicating pipe 24 positioned at one end port of the communicating pipe 24 of bottom, enter the silicone oil oil bath in outer tube 21 via communicating pipe 24
In, so set, being compared to the exhaust end of exhaust pipe 12 being inserted directly into the mode of silicone oil, it is straight with silicone oil to avoid exhaust pipe 12
Contact, when sintering furnace pressure has mutation, the space in inner tube 22 is as the turbulent space of buffering, and there is no off-gas flows jump
The danger moved and cause silicone oil to rock；
2. communicating pipe 24 and the setting of inner tube 22, avoid exhaust pipe 12 and are contacted with the direct of silicone oil, due to being high in sintering furnace
Vacuum negative pressure condition, and the external world is normal pressure or positive pressure environment, exhaust pipe 12 in sintering furnace with connecting, if there is misoperation
Or during gas leakage, extraneous positive pressure environment can be handled air along the connecting tube in gas ignition device and with exhaust gas oil bath
Device gas outlet connection connecting tube push back in exhaust gas oil bath processing unit, at this time into outer tube 21 ambient atmos along
Silicone oil is fallen to press in meeting inner tube 22 by communicating pipe 24, and the amount of the silicone oil held in outer tube 21 most senior general's inner tube 22 is full of, without
Silicone oil is pushed back directed along air inlet and exhaust pipe 12 in sintering furnace, cause security incident, moreover, in silicone oil by along even
When siphunculus 24 pushes back inner tube 22, operating personnel can clearly see, can also prevent the generation of such case in time；It is compared to
The exhaust end of exhaust pipe 12 is inserted directly into the mode of silicone oil, when such a situation occurs, silicone oil is directly just overwhelmed by the external world and is depressed into
Enter along exhaust pipe 12 in furnace body, cause security incident；
3. communicating pipe 24 and the setting of inner tube 22, have elongated the path that hydrogen is discharged in residual gas, have equally also elongated hydrogen
The path of tempering, in firing device, hydrogen is fuel gas, if directly inserted using the existing exhaust end by exhaust pipe 12
Entering the mode of silicone oil, the hydrogen lighted can be sometimes directly entered in silicone oil along the connecting tube in firing device, then along
Air inlet enters in furnace body, causes security incident, even and if the hydrogen lighted in the present invention sometimes can be along in firing device
Connecting tube and the connecting tube that is connected with the gas outlet of exhaust gas oil bath processing unit enter in exhaust gas oil bath processing unit, at this time
Hydrogen or the hydrogen lighted can only exist inside outer tube 21, more will not be along air inlet without being directly entered in inner tube 22
Into in furnace body.
During high temperature sintering furnace sintering work of the present invention, in-furnace temperature can reach 1600 DEG C -1900 DEG C, furnace interior part
It is all or part of to be made of refractory metal material, such as molybdenum, tungsten etc..
Module or unit in device of the embodiment of the present invention can be combined, divided and deleted according to actual needs.
The above disclosure is only the preferred embodiments of the present invention, cannot limit the right model of the present invention with this certainly
Enclose, one of ordinary skill in the art will appreciate that realize all or part of flow of above-described embodiment, and will according to right of the present invention
Made equivalent variations are sought, still falls within and invents covered scope.
