The rotary body center easily occurred in the rotatory sealing that the present invention is particularly in medium-and-large-sized equipment for rotatory sealing
Beat bring it is poorly sealed, sealing effectiveness is poor, seal member short life the problem of, creatively by rotary body and fixed body it
Between rotatory sealing done resolution process, i.e., the rotatory sealing between rotary body and seal assembly is decomposed into by rotatory sealing, it is close
Flexible bounce sealing between sealing assembly and fixed body.So by original rotation, bounce, twisting, sliding, concentrate in together
Complexity sealing, is changed into a single rotatory sealing and the multinomial motion beated, twist, slid is changed into an absorption by one
Bounce, twisting, the flexible sealing of the flexible variety of sliding；Both sealings, which can all reach, to be fully sealed.
In the rotary body seal assembly provided circumferentially about being rotatably connected with rotary body, seal assembly and rotary body connect
Touch, during seal assembly and rotary body contact is ensured, realize the good rotatory sealing between seal assembly and rotary body,
The seal assembly is connected by flexible connection body with the fixed body, and flexible connection body one end is connected with seal assembly, another
End is connected with the fixed body, during rotary body rotates, seal assembly and rotary body relative motion, but it is relative
During motion, radially as rotary body is beated up and down, and seal assembly is during bounce, with the fixed body
It is to be connected by flexible connection body, flexible connection body itself is soft, can occurs on various deformation, particularly radial direction
Deformation, the change in location on seal assembly will not be transmitted on fixed body, it is possible to realize fixed body it is motionless with it is close
Sealing assembly bounce long-term co-existence, be independent of each other, seal assembly between ideal axis and actual dynamical axis position it is frequent
Dynamic change, can be by flexible connection body by itself flexible automatic digestion, and flexible connection body may insure fixed body and sealing group
It is non-interference on position between part, the reliable sealing between fixed body and seal assembly can be realized again.
In the design process of rotatory sealing, how the theory of person of ordinary skill in the field allows rotation if all being concentrated on
Center bounce in the rotary course of body is smaller, or preferably in one very small scope, to adapt to fixed body and rotation
The deformation of seal between body, that is to say, that the bounce to reduce rotary body in all its bearings is the technology of art
The psychological direction of propulsion of technology of the personnel when doing rotatory sealing design, this is the most important side of skilled artisan
To.And the center in the rotary course of rotary body is beated when can not reaching ideal dimensions, the skill of art
Art personnel are usually to try every possible means to increase the deformation size and deformability of seal, allow the deformation of seal to become large-sized, with suitable
The pivot bounce amplitude of rotary body is answered, reduces gas leakage as much as possible.What is more important, the thinking designed in rotatory sealing
On either large scale equipment or small-sized setting, it is more compact between rotary body and fixed body, smaller spacing be realize all seal
The starting point and foothold, so more precision manufactureing material, more high-end designs technique with preferably reduce rotary body center bounce
It is direction with increase seal deformation size.Absolute not will recognize that goes to allow with a kind of with the altogether irrelevant part of rotatory sealing
With the bounce of compensation rotary body center bounce, that is to say, that what the present invention did the rotatory sealing between rotary body and fixed body
Resolution process, i.e., be decomposed into the rotatory sealing between rotary body and seal assembly by rotatory sealing, seal assembly and fixed body it
Between flexible bounce sealing, it with the conventional design of person of ordinary skill in the field is entirely different design direction, institute to be
Category those skilled in the art do not have any reason to obtain being connected the technical inspiration of rotatory sealing with flexible connection body, are used for
Solve the problems, such as the rotatory sealing between rotary body and fixed body in rotary body hopping process.
In addition, particularly surprising, in the rotary course of rotary body, flexible connection body can not only adapt to rotary body and exist
When center is beated, seal assembly allows seal assembly to be beated in radial direction with rotary body in the tripping problems of radial direction, close to ensure
The axiality problem of sealing assembly and rotary body, the pressure and deformation suffered by seal assembly inner seal liner is improved in normal range (NR)
The life-span of its sealing effectiveness and seal.Meanwhile, during the rotation of rotary body, the seal in seal assembly is revolved
In the friction of swivel, the power being subject in the circumferential, meeting off-load to flexible body, seal assembly can also become in circumferential position
The characteristics of change, flexible connection body itself, determines, can also allow seal assembly that certain twisting change occurs in circumferential position,
This friction revolving force is by flexible body, and final off-load causes the reaction force of twisting on fixed body, and reaction force leads to again
Crossing flexible body makes seal assembly limited in rotation, can only be in a small range.And in seal assembly after rotating in a circumferential direction, inevitable band
The a certain degree of distortion of dynamic flexible connection body, this distortion can change the pulling force suffered by flexible connection body, and this pulling force is limited again
Seal assembly processed continues rotating in a circumferential direction, so flexible connection body is used in seal assembly circular runout and the synthesis circumferentially rotated
Under, it is allowed to seal assembly circular runout, restriction is circumferentially rotated, and the sealing between seal assembly and fixed body is completed again, is to be in
Critical component in dynamic rotary sealing.
What is more important, the fixed body connected as flexible connection body and follow-up supporting mechanism, seal assembly, rotation
Body, flexible connection body and follow-up supporting mechanism are the combinations of matching, respectively the larger center bounce of corresponding rotation body, sealing group
Part and the more stable spacing of rotary body, less frictional force, the normal deformation of seal and preferable sealing effectiveness, only its compared with
Small frictional force could be met the change of seal assembly radial direction and pining down for circumference by flexible connection body, so the present invention is one
Dynamic entirety innovation system is the technology that mutually supports between each part under opening one's minds based on rotatory sealing into
Really.
More peculiar, the rotary body and fixed body beated at center are during work, rotatory sealing of the present invention
Mechanism is actually not intended to limit the center bounce of rotary body, and allows the bounce of rotary body center in the case of not influenceing sealedly by soft
Property connector compensation center bounce, make bounce stop conducting to fixed body, it is allowed to seal assembly with rotary body center beat, will
Center is beated and two power of circumferential friction are effectively eliminated with flexible connection body, passes through the operation of a period of time, the center of rotary body
Bounce amplitude is unexpectedly gradually reduced, and can be slowly easier to one in the range of controlling, and this speed is not compared to being
For the rotary body of seal member liberation, speed is very fast, it might even be possible near more than twice.Although the shape of big-and-middle-sized kiln body
Also local deformation can slowly occur during rotation, shape is more beneficial for completing rotary body closer to preferable rotary body
Rotation, but as this speed closer to rotary body, strictly make people unexpected.Because the knot of big-and-middle-sized rotary body
Structure is generally metal structure form, and the scale of construction is very big, internal to carry more material again, and along with high-temperature chemical reaction process,
Cylindrical shape can be such as during rotation for the big-and-middle-sized rotary body or apparatus for rotating for not expecting in High Temperature Rotating high-mechanic
This is fast to deform upon, and is more beneficial for rotation, center bounce is also smaller, is also more conducive to seal.
By setting circumferential spacing component on seal assembly and setting limiting component on fixed body, make described
Seal assembly is radially beated with the rotary body along center line and circumference is motionless.The circumferential limiting component can use a variety of shapes
Formula, achievable seal assembly is circumferential motionless during radial floating, and the circumferential limiting component is circumferential to seal assembly
Progress is spacing, and the direct off-load of rotation friction that seal assembly is produced when rotary body is rotated is on fixed body, so as to avoid
The frictional resistance that seal assembly is produced passes to flexible connection body, the flexible connection body is had longer service life.Flexibility is even
Junctor can use rubber, flexible stronger, can effectively ensure that flexible connection body is deformed with the rotation of rotary kiln, swung
And play, by the compound movement of flexible connection body, change in location between compensation fixed body and rotary body solves seal assembly
The effect of circumferential torsion may be produced to flexible connection body during rotatory sealing, flexible body is reduced stress as far as possible,
Solve the problems produced in the rotatory sealing that rotary body bounce is brought well simultaneously.The circumferential limiting component is set
It on fixed body, can also be arranged on other fixed bodies, or even be provided in flexible connection body, as long as can be to sealing group
The effect of part applying power, prevents its circumferential movement.
The present invention is provided with follow-up supporting mechanism on the seal assembly, is limited and sealed by the follow-up supporting mechanism
The axiality of component and the rotary body so that can not between two pivots of seal and rotary body in seal assembly
There is big deviation, so that ensure that the center of the sealing ring in seal assembly and the pivot of rotary body can not have big deviation,
Just evenly, the normal sealing compensation gap ability of sealing ring is guaranteed for seal assembly and rotary body peripheral distance, is servo-actuated branch
Support mechanism had both ensured there is appropriate gap with rotary body, it is impossible to produce catching phenomenon in some contact site, while servo-actuated support machine
Gap again can not be excessive between structure and rotary body, to ensure sealing；If without follow-up supporting mechanism or follow-up supporting mechanism with
Gap is excessive between rotary body, and seal assembly is impossible to ensure coaxial with rotary body, between seal assembly and rotary body periphery
Serious non-uniform phenomenon occurs in gap, and the center of the sealing ring of seal assembly and the center offset distance of rotary body are excessive, sealing ring
Sealing may produce two kinds of phenomenons simultaneously, on the one hand, at the position that gap is too small, sealing ring gross distortion, or even sealing ring
Lip is by squeeze crack, heavy wear, on the other hand, at the excessive position in gap, between the maximum compensation ability of sealing ring can not be filled up
Gap, causes the gas leakage at the position.Follow-up supporting mechanism has a variety of ways of realization, seal assembly both sides or it is middle set slide or
Person's rolling mechanism, is always ensured that with rotary body circumferentially opposed motion is occurring for seal assembly always, ensure always seal assembly with
Axiality between rotary body within the specific limits because the presence of follow-up supporting mechanism so that seal assembly is in rotary body footpath
To direction always as rotary body center is beated, during being beated at center therewith, axiality between the two is in certain model
In enclosing, both relative motions are unaffected, the need for the compensation ability of sealing ring fully meets seal clearance, realize both
Reliable sealing.
The seal assembly includes setting sealing ring, sealing ring locating ring, sealing ring in sealing support body, the sealing frame body
Gland.
Flange is set between the fixed body and the flexible connection body, is easy to the installation of equipment.
The grey part of gear is set, is to enter the position between seal assembly and rotary body to reduce dust, to mitigate to sealing
The abrasion of circle, additionally is able to play fine heat-blocking action, can mitigate in kiln body high temperature to flexible connection body and the hot spoke of sealing ring
Penetrate, protection flexible connection body and sealing ring.Preferably, heat sink is set between the cylinder and rotary body, can cool down into
Enter seal area gas, be more beneficial for reduction to the requirement of the heatproof of flexible connection body and sealing ring material, improve flexible connection body and
The life-span of sealing ring.More preferably, in the outside of heat sink, i.e., away from fixed body close to the position of sealing ring, in kiln hood outer wall
A upper affixed back-up ring, is advisable between this back-up ring and shell flange with not producing friction, back-up ring and heat sink rise jointly gear ash,
Thermal radiation resistant is acted on.
