In stating, the accompanying drawing of required use is briefly described, it should be apparent that, the accompanying drawing in describing below is only the utility model
Some embodiments, for those of ordinary skill in the art, on the premise of not paying creative work, can also basis
These accompanying drawings obtain other accompanying drawing.
Fig. 1 is overall structure schematic diagram of the present utility model.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of the utility model, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of making creative work
The every other embodiment being obtained, broadly falls into the scope of the utility model protection.
With reference to shown in Fig. 1, a kind of self-adapting seal rotary furnace, including body of heater 1, body of heater surface configuration has rotating driving device
2, body of heater two ends are all arranged with kiln head cover 3, and kiln head cover surface configuration has kiln feeding relief portion 4, kiln head cover inwall and body of heater side
It is additionally provided with labyrinth seal structure 5 between face, the corresponding kiln head cover of labyrinth seal structure is additionally provided with gas access conduit 6,
It is additionally provided with installation baffle plate 7 bottom kiln head cover, baffle plate is installed and is positioned between kiln head cover interior side and labyrinth seal structure setting
Having graphite packing 8, opposite side being evenly arranged with some hold-down mechanisms 9, hold-down mechanism passes through installs baffle plate and by graphite packing
It is pressed on labyrinth seal structure.Body of heater two ends are the passage through with air, and this is set by kiln head cover cover at two, and passes through stone
Disc root realizes sealing, and the compacted all the time mechanism of graphite packing is pressed on the labyrinth seal structure of body of heater, and therefore body of heater rotates
