Abstract
The invention discloses a rotary sealing device for a reaction kettle stirring bar. The rotary sealing device comprises the stirring bar, a standard connector arranged at the lower portion of the stirring bar, a rotor arranged at the middle portion of the stirring bar, and a lock nut arranged at the upper portion of the stirring bar. An inner guiding casing pipe is arranged between the standard connector and the stirring bar, and a loosening nut is arranged at the outer portion of the standard connector. The rotor comprises a top rotor body and a bottom rotor body, a glass bearing seal is arranged in the bottom rotor body, and a bearing seal is arranged in the top rotor body. A lock hoop is arranged in the lock nut. The rotary sealing device for the reaction kettle stirring bar is high in corrosion resisting capability, resistant to the high temperature and long in service life, the vacuum degree in a reaction kettle can be high through the rotary sealing device, extremely few friction scraps are generated in the using process, and even a small number of friction scraps are generated, the scraps cannot fall into the reaction kettle, and purity and cleanliness of materials in the reaction kettle can be effectively guaranteed.
Description
Technical field
The present invention relates to sealing device technical field is and in particular to a kind of rotatory sealing of reactor stirring rod fills.
Background technology
Generally, most of acid, alkali chemical reaction are to be completed by stirring in glass reaction kettle under uniform temperature, certain vacuum degree.When carrying out chemical reaction under vacuo, due to poorly sealed at stirring rod, can leak air at the sealing of stirring rod so that vacuum does not reach requirement, impact reaction.In order to solve the stirring rod sealing problem in the middle of reacting, in prior art, generally improve sealing effectiveness using the sealing stirring plug that fluororubber (for example: politef) is made.Teflon stir plug mainly includes the static seal part contacting with reaction bulb bottleneck portion, connecting with static sealing portion split-phase and being located at has a dynamic sealing medium o type rubber ring thereon, and the block being connected by rib-loop with dynamic sealing medium, and the centre bore putting stirring rod through whole plug.
Teflon stir plug in use there is problems in that (i) when reactor temperature is higher and system in containing acid, alkali chemical reagent when, can to rubber ring produce corrosion.When stirring rod installs out of plumb, friction can be produced to rubber ring in stirring rod high-speed rotation, easily make rubber ring deformation, abrasion, these all can lead to rubber ring to lose sealing function, once annular seal space is revealed, serious pollution will be caused to the external world, seriously jeopardize the environment in the external world and the person of staff.(), after rubber ring loses sealing effectiveness, in reactor, vacuum occurs decline, needs the rubber ring damaging is changed.Some vacuum chemical reaction times are longer, have up to more than 20 hours, and stirring in experimentation, must be carried out continuously.Experiment therefore can not be stopped rubber ring being changed so that vacuum does not reach requirement, impact experiment during whole reaction.
And of the prior art former similar stirring sealing there is problems:
1. former similar stirring sealing, has that chemical resistance is poor, service life is short, the defect such as vacuum difference.
2. former similar stirring sealing, is used mostly fluororubber as raw material, has certain toxicity, can have certain impact on reaction result.
3. former similar stirring sealing, in use, stirring rod with sealing ring directly contact and produces friction, easily produces friction chip in use.Chip is scattered after entrance reactor, and the quality of the impact purity of reaction mass and cleanliness factor or impact reaction product or directly result in is reacted unsuccessfully.
Content of the invention
For above-mentioned the deficiencies in the prior art, it is an object of the invention to provide a kind of corrosion resistance is strong, high temperature resistant, the rotary sealing appts of long service life reactor stirring rod.It is high that it enables in reactor vacuum, few in use produce friction chip, even and if produce a small amount of chip that rubs, chip also will not fall behind purity and the cleanliness factor that material in reactor can be effectively ensured in reactor.
For solving problems of the prior art, the concrete technical scheme of employing is:
A kind of rotary sealing appts of reactor stirring rod include stirring rod, the modular connection being arranged on stirring rod bottom, the lock nut being arranged on rotor in the middle part of stirring rod, being arranged on stirring rod top；It is provided with internal guide thimble between described modular connection and stirring rod, be provided with outside modular connection and unclamp nut；Described rotor includes top rotor and bottom rotor, and bottom rotor is internally provided with glass bearing seal, and described top rotor is internally provided with bearing seal；Described lock nut is internally provided with locking clip.
Preferably technical scheme, the rotary sealing appts of described reactor stirring rod also include sealing, and this sealing is located between lock nut and stirring rod, and are located at below described locking clip.
Further preferred technical scheme, is provided with precision sealing between described stirring rod and bearing seal, and this precision sealing bottom extends downward modular connection upper end, and this precision sealing bottom and modular connection upper end offset.
The material used in above-mentioned sealing device, all using peek material, has the features such as high-purity, low volatility and avirulence.
By adopting such scheme, compared with prior art, it has the technical effect that a kind of rotary sealing appts of reactor stirring rod of the present invention
1. due to being rotary seal between the stirring rod of the sealing device of the present invention and stirring rotating seal, the sealing member of rotor rotates together with stirring rod, rubs thus without producing.
2. the produced friction of the motion of whole sealing device, is only limitted to the periphery of sealing device, even if there being slightly chip, also will not fall in reactor, the material in reactor not being had any impact.
3. the sealing device of the present invention can make that the vacuum of reactor is high, corrosion-resistant, no abrasive dust falls in kettle, therefore can be widely used for biology, chemical pharmacy, fine chemistry industry, the research and development in the field such as nanosecond science and technology and among producing.Contrast traditional sealing, this sealing device can also use in the very high laboratory of hygienic requirements and gmp workshop.
