Description
Technical field
The utility model relates to rotary kiln technology more particularly to a kind of rotary kiln end face seal structures.
Background technique
Rotary kiln is the commonly used equipment in chemical industry.It is inevitable between the kiln body and kiln tail cover of rotary kiln rotation to obtain
There is gaps, leak from kiln hood to prevent in outside air sucking rotary kiln and prevent kiln gas from from carrying material,
Setting seal member is needed on rotary kiln.There are many kinds of the sealing means of rotary kiln, but all there is different degrees of poorly sealed, leakage
Wind problem, when being especially positive atmosphere inside rotary kiln, the gas leak in rotary kiln can pollute air, cannot
Meet the requirement of environmental protection.Why the sealing of rotary kiln will appear poorly sealed problem, be primarily due to existing sealing means
The radial beat error generated when rotary kiln rotation cannot be eliminated.Radial beat error is since rotary kiln inclines during rotation
There are biggish radial-plays and kiln body in manufacture, installation, operation process that own form error generates for the kiln body tiltedly installed,
It is even more big that its margin of error reaches 15mm.Rotary kiln kiln body can also generate axial float in rotary course, lead to seal member
It is deformed by significantly bending, to leak out.In addition, the play of rotary kiln kiln body axially and radially is easy to cause sealing
Breakage rate is high for component, and maintenance rate is high, and maintenance difficulty is big, increases production cost.
Utility model content
In order to solve the above-mentioned prior art problems, the utility model provides a kind of rotary kiln end face seal structure.
To achieve the above object, the utility model provides the following technical solutions: a kind of rotary kiln end face seal structure, including
Static components and moving ring assembly, the static components include at least two stationary rings；Two neighboring stationary ring forms a U-shaped seal chamber
Room；The side of static components is equipped with sliding ring；The sliding ring slides axially sealing on ring support；It is described
Ring support is fixed in the kiln hood of rotary kiln；The moving ring assembly includes rotating ring；The quantity of the rotating ring and U-shaped sealing
Chamber quantity is consistent；The rotating ring is fixed at the external side of rotary kiln；The U-shaped seal chamber of rotating ring ring body insertion corresponding thereto
It is indoor；Radial clearance is equipped between the insertion end of rotating ring and U-shaped sealed chamber corresponding thereto；The both ends of the surface of rotating ring and and its
The first packing sealing ring is equipped between opposite U-shaped sealed chamber side.
Preferably, the outside of the sliding ring is equipped with the second packing sealing ring；The ring support is equipped with U-shaped recessed
Slot；The ring body of second packing sealing ring is inserted into U-shaped groove；It is equipped with to be slidingly sealed on the outside of the insertion end of second packing sealing ring and open
Tight device.
Preferably, the moving ring assembly further includes rotating ring flange；Rotating ring flange is set to the external side of rotary kiln；Rotating ring passes through
Rotating ring fixing bolt is fixed on rotating ring flange.
When rotary kiln works, rotating ring, which is fixed in kiln body, to be moved with kiln body and rotates in U-shaped sealed chamber.The two of rotating ring
The U-shaped sealed chamber side of end face corresponding thereto forms sealing surface.Radial clearance is adapted to production when the rotation of rotary kiln kiln body
Raw radial beat error, it may be difficult to which the radial beat error of solution is converted to controllable end face Run-out error, eliminates sealing
Component is because leaking out and wearing caused by radial beat error.Sliding ring is set by the sealing that slides axially of the second packing sealing ring
In on ring support, so that the stationary ring being fixedly connected with sliding ring can overcome friction between rotating ring, stationary ring to generate
Make the active force of stationary ring rotation and only slided with the axial float of rotary kiln, because axial float is to close when eliminating rotary kiln rotation
The adverse effect that seal structure generates, enhances the leakproofness of sealing structure, extends the service life of sealing structure.
The utility model seal member is less, and structure is simple, can efficiently solve the radial direction generated when rotary kiln rotation
Air Leakage, the wear problem to seal member, improve seal member significantly caused by Run-out error and axial float
Sealing reliability extends the service life of seal member, provides guarantee for the functional reliability of rotary kiln.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is enlarged diagram at A in Fig. 1.
In figure: 1U type groove, 2 are slidingly sealed tensioning apparatus, 3 stationary rings, 4 ring bolts, 5 ring supports, 6 are slidingly sealed
Ring, 7 rotating rings, 8 rotating ring flanges, 9 cool wind hoods, 10 first packing sealing rings, 11 radial clearances, 12 second packing sealing rings, 13 kilns
Hood, 14 kiln bodies.
Specific embodiment
The embodiments of the present invention are further illustrated with reference to the accompanying drawing.
Referring to Fig. 1-2, a kind of rotary kiln end face seal structure, including static components and moving ring assembly.The static components
Including two stationary rings 3.Two stationary rings 3 form a U-shaped sealed chamber by two connections of ring bolt 4.The side of static components
Equipped with sliding ring 6.The moving ring assembly includes rotating ring 7 and rotating ring flange 8.Rotating ring flange 8 is fixed at rotary kiln kiln body
14 9 outside of cool wind hood.In the specific implementation, adjustment flange can be used in rotating ring flange 8.Rotating ring 7 is solid by rotating ring fixing bolt
It is scheduled on rotating ring flange 8.7 ring body of rotating ring is inserted into U-shaped sealed chamber.It is equipped between the insertion end of rotating ring 7 and U-shaped sealed chamber
