Technical field
The present invention relates to mechanically-sealing apparatus technical field, especially a kind of rotating ring and stationary ring are using pressure balanced design New enamel reaction kettle single-end surface machine sealing.
Background technology
Enamel reaction still is a kind of excellent corrosion resistant apparatus, it have glass stability and metal high intensity it is dual Advantage, enamel reaction still pressure-bearing is relatively low, and corrosion resistance is strong, low cost, be widely used in chemical industry, oil, medicine, pesticide, The industries such as food, since the anti-impact force of enamel is excessively poor, any metal, hard object, which hit it, can cause enamel broken Damage, therefore prevent that any metal, hard object contact during enamel still use；Therefore a kind of not easy to wear, sealing is provided The enamel reaction still single-end surface machine sealing haveing excellent performance is the technical issues of those skilled in the art are badly in need of solving.
Invention content
The technical problem to be solved in the present invention is to provide it is a kind of it is simple in structure, nonabradable New enamel reaction kettle is single-ended The working method of face machine envelope.
In order to solve the above technical problems, New enamel reaction kettle single-end surface machine sealing provided by the invention, including：It cooperates The stationary ring and rotating ring of sealing, enamel flange, isolation ceramic ring, pressing plate, stationary ring mounting base；In the through-hole of the enamel flange center It is embedded bushing, annular boss, the upper end of the lower face of the annular boss and the enamel flange are set in the middle part of the outer wall of the bushing Face paste closes setting；The ceramics shading ring is nested on the bushing, the lower face of the ceramics shading ring and the annular boss Upper surface fitting setting；The outer wall nesting pressing plate and stationary ring mounting base of the ceramics shading ring, the stationary ring are embedded described In stationary ring mounting base, the upper surface of the stationary ring and the lower face sealing of the rotating ring coordinate, and the pressing plate is pacified with the stationary ring Multiple counterbalance springs are set between dress seat, multiple spacer pins are set between the stationary ring mounting base and the pressing plate, so that described Counterbalance spring can push stationary ring to keep sealing with the rotating ring when rotating ring is rotated with shaft；Benefit is set by the way of stationary ring compensation Spring is repaid, sealing effect can be improved.The working method of the New enamel reaction kettle single-end surface machine sealing, including：Deform screw When screwing, holding circle stress deformation, and then the shaft being arranged in holding circle is clamped.When occur reaction kettle mouth with stirring When the case where axis out of plumb, stationary ring may be implemented adaptively to be bonded with rotating ring.
Further, New enamel reaction kettle single-end surface machine sealing further includes the clamping ring being fixedly linked with the rotating ring, the folder The inner wall of tight ring is arranged holding circle, and multiple deformation screws are arranged on the clamping ring, and each head for deforming screw passes through the clamping The side wall of ring is in contact with the outer wall of holding circle, when so that the deformation screw screwing, holding circle stress deformation, and then to setting Shaft in holding circle is clamped.
Further, the first O-ring seal is set between the inner wall of the rotating ring and the shaft of reaction kettle and baffle ring progress is close Envelope, the upper surface of the baffle ring are bonded setting with the inner face of the holding circle, the lower face of the baffle ring and described first O-shaped Sealing ring fitting setting, to obtain better seal effect.
Further, the bushing is polytetrafluoroethylene bushing, and the baffle ring is polytetrafluoroethylene (PTFE) baffle ring, is had excellent resistance to Mill property and lubricity, avoid metal material from being in contact with enamel reaction still.
Further, the stationary ring inner wall with it is described be isolated between the outer wall of ceramic ring the second O-ring seal is set, with obtain Better seal effect.
Further, New enamel reaction kettle single-end surface machine sealing further includes the locating piece for controlling counterbalance spring decrement, The locating piece carries out pushing limit to the stationary ring pedestal, and before which pulls out, spring can not stretch, and stationary ring is static；This is fixed After position block is pulled out, spring retractable, for driving stationary ring along enamel flange axial displacement.
The technique effect of invention：（1）The New enamel reaction kettle single-end surface machine sealing of the present invention is adopted compared with the existing technology It is in contact with reaction kettle with the enamel flange of non-metallic material, isolation ceramic ring and polytetrafluoroethylene bushing, avoids metal material It contacts, can prolong the service life in deep-etching or enamel reaction still operating mode application；（2）It is arranged between stationary ring and pressing plate and mends Spring is repaid, stationary ring is compensated in rotary course, sealing effect can be improved；（3）Rotating ring and stationary ring use pressure balance Design, can meet the application of the higher operating mode of pressure；（4）The verticality of enamel reaction still agitating shaft and reaction kettle mouth under normal circumstances It is not very high, the not high service life for influencing mechanical seal of verticality, the mechanical seal counterbalance spring of the application is arranged in stationary ring In the following, stationary ring has enough floating spaces；When there is reaction kettle mouth with the case where agitating shaft out of plumb, stationary ring may be implemented certainly Adaptation is bonded with rotating ring, reaches longer service life.
