Property, general radiation pipe and heating tube are using integral type heat resisting steel material-structure, and under long-time hot operation state, heating tube makes
There was only 1 year or so with the service life, the later period has the problems such as maintenance blowing out number is frequent, and maintenance cost is high.
Utility model content
In place of the purpose of this utility model is to overcome above-mentioned deficiency, to provide a kind of annular furnace heating radiation seal of tube
Radiant tube and heating tube are separated, and improve the sealing performance of radiant tube by structure, reduce the maintenance cost of equipment.
According to technical solution provided by the utility model, annular furnace heating radiation tube seal structure includes furnace body, radiant tube
And heating tube, it is characterized in that: being equipped with radiant tube in furnace body, radiant tube is equipped with locking end face, locks the upper and lower side difference of end face
Equipped with sealing flange and locking flange, sealing flange and locking flange will lock end face and clamp up and down and pass through multiple internal locking spiral shells
Bolt locks sealing flange and locking flanged joint；Sealing flange upper end is equipped with flange end cap, and flange end cap is by sealing flange pressure
Flange end cap, sealing flange and furnace body are tightly connected into locking in furnace body upper surface and by multiple outer locking bolts；The heating
Pipe protrudes into radiant tube after flange end cap and sealing flange.
Further, radiant tube is integrally formed using silicon carbide ceramics micro mist.
Further, multiple outer locking bolts are uniformly distributed along flange end cap circumferencial direction.
Further, gasket seal is equipped between flange end cap and sealing flange.
Further, multiple internal locking bolts are uniformly distributed along sealing flange circumferencial direction.
Compared with the prior art the utility model has the advantage that
The utility model structure is simple, compact, reasonable, and radiant tube is integrally formed using ceramic material, with heat-resisting steel spoke
It penetrates pipe to compare, service life extends 2 times or more；Radiant tube uses upper and lower two flange seal clampings, improves furnace gas air-tightness；Add
Heat pipe is separated with radiant tube, it is ensured that radiant tube makes full use of, and is beneficial to reduce maintenance cost, in not blowing out, quickly more
Radiant tube is changed, furnace outage time is reduced, guarantees the continuity of equipment work.
Detailed description of the invention
