Existing rotary kiln volume and diameter are all very large, and all can affect the sealing of kiln body when kiln body produces small circular runout and axial float when rotating, cause material, dust and Leakage Gas, single sealing means can not meet higher seal request usually.
Common contact seal has flake type to seal and friction disk type sealing.Although flake type sealing device structure is simple, causes scale serious wear due to unlubricated, affect sealing effectiveness; Friction-type sealing generally uses oil lubrication friction plate, and pipeline is complicated, and under the environment that temperature is higher, lubricating oil easily evaporates and runs off, and lubricates insufficient, accelerates friction disc wear, and waste lubriation material, affects environment.
Common non-contacting seal has labyrinth sealing and vapour-pressure type sealing.All there is same problem in non-contacting seal: does not contact mutually between cylindrical shell with hermetically-sealed construction, and reserving gaps is comparatively large, and the material that leaks out is serious, and sealing effectiveness is poor.
Utility model content
Technical problem to be solved in the utility model is: provide a kind of good sealing effect, to the axial float of cylindrical shell and circular runout adaptability is good, friction loss is little pyrolysis rotary kiln hermetically-sealed construction.
The technical scheme adopted for solving the problems of the technologies described above the utility model is: pyrolysis rotary kiln hermetically-sealed construction, comprise cylinder of rotary kiln, the outer wall of cylinder of rotary kiln end is provided with air-cooled cover with being along the circumferential direction fixedly connected with, the cooperation of cylinder of rotary kiln end is provided with kiln hood, kiln hood end coordinates with air-cooled cover and is provided with labyrinth sealing, at least one group of friction-type sealing is provided with inside labyrinth sealing, friction-type sealing comprises retainer plate, elastic telescopic part, brake pad, drag ring, retainer plate is located at kiln hood inwall with being fixedly connected with, drag ring is located at air-cooled putting with being fixedly connected with, brake pad the inner and drag ring close contact, outer end is stretched in the groove of retainer plate, and the two sides of brake pad respectively with the two sides close contact of retainer plate groove, elastic telescopic number of packages amount is more than one piece, circumferencial direction interval along retainer plate is arranged, elastic telescopic part one end contacts with brake pad outer end, the other end contacts with the bottom portion of groove of retainer plate.
Further: friction-type number of seals is two groups, form the first air chamber between two groups of friction-type sealings, the first air chamber is filled with protection gas by air inlet pipe, makes the gas pressure in the first air chamber be greater than the gas pressure of the first air chamber both sides.
Further: cylinder of rotary kiln end is provided with dust block board.
Further: elastic telescopic part is elastic rubber or spring.
Further: elastic telescopic part is spring, elastic telescopic part two ends are also provided with pad.
Further: brake pad is graphite block.
Further: protection gas is steam.
The beneficial effects of the utility model are: by labyrinth sealing, friction-type sealing being combined, composition composite seal structure, efficiently solve the problem of sealing effectiveness difference, elastic telescopic part is provided with in friction-type sealing, can adapt to axial float and the circular runout of cylindrical shell, friction loss is less, in addition, further in conjunction with vapour-pressure type sealing, sealing effectiveness is better.
Accompanying drawing explanation
