Description
Technical field
The present invention relates to a kind of stirrer mechanical seal device.
Background technology
It is also growing day by day to the demand of power consumption now with China's rapid development of economy and industrialized constantly propulsion, all trades and professions；About 75% electric power comes from coal in the whole power industry in China, but, the content of sulphur is up to 1% ~ 2% in coal, the sulfur dioxide for causing coal burning to be discharged has accounted for the 93.9% of total emission volumn, national sulfur dioxide annual emissions are up to more than 20,000,000 tons, occupy first place in the world, if sulfur dioxide gas caused by burning coal is exhausted directly in air without processing, very big harm will be caused to health and atmospheric environment, State Environmental Protection Administration has taken compulsory measure, it is required that newly-built and built coal-fired power plant must pass through flue gas desulfurization device before fume emission.Wherein, gypsum wet FGD systems（Abbreviation FGD）Process operation good reliability, it is current technology maturation, the sulfur removal technology being most widely used the most to the strong adaptability of coal type change.And the sidepiece agitator mechanical seal of FGD systems absorption tower is due to its severe operating mode（Seal cavity volume is small, without outer flushing and interior flushing, medium particle containing slurry solids 30% ~ 40%）, mechanical seal is easily failed, it is difficult to ensure that service life.The mixed slurry viscosity of the media such as MgCl2, MgSO4, CaSO4 is generally very big, and the acid medium liquid medium that PH values are 3~3.5 is once a leak occurs, easily cause the pollution and destruction to environment.
Because the agitating shaft of general agitator is longer, degree of disturbing is larger, and operating mode is severe in addition, the situation of dynamic and static ring fragmentation easily occurs.So many agitator mechanical seals carry bearing arrangement, aligning effect is played, reduces influence of the agitating shaft degree of disturbing to mechanical seal.And present agitator mechanical seal, bearing trim designs, its structure are generally：Including axle sleeve, rotating ring and stationary ring are provided with outside axle sleeve, seal receptacle is provided with outside stationary ring, bearing and bearing gland, typically brearing bore close-fitting is directly sleeved in axle sleeve outer rim, bearing outer rim is also directly to be inserted in seal receptacle, assemble extremely difficult, mechanical seal goes wrong in use, remove, repaired, bearing is not torn open not get off yet, because agitator mechanical seal dynamic and static ring typically all uses SiC materials, this material is fragile, so in assembling and maintenance all easily mechanical seal dynamic and static ring and other damage parts, mechanical seal damage parts and mechanical seal is caused not to use.
The content of the invention
The present invention provides a new pattern for agitator mechanically-sealing apparatus product scope, including axle sleeve, rotating ring and stationary ring are provided with outside the axle sleeve, is provided with seal receptacle, bearing and bearing gland outside stationary ring, the seal face of the rotating ring and stationary ring fits, spring is installed between the stationary ring and seal cavity, the spring one end is fitted with stationary ring, and the other end is arranged in seal receptacle, and the moving ring sleeve is on axle sleeve, and be connected with axle sleeve, seal is installed therebetween.Bearing inner sleeve is connected with bearing, bearing gland using small―gap suture, and bearing inner sleeve uses mode connects for screw with axle sleeve, driving conical ring.
Brief description of the drawings
Accompanying drawing is the structural representation of the present invention, wherein：1st, axle sleeve 2, rotating ring 3, stationary ring 4, seal receptacle 5, spring locating shaft 6, spring 7, rotating ring stop pin 8, stationary ring stop pin 9, bearing gland 10, lip envelope 11, end ring 12, bearing 13, jump ring 14, bearing inner sleeve 15, limit locking pieces 16, driving conical ring 17, soket head cap screw 18, soket head cap screw 19, jackscrew 20, positioning screw 21, soket head cap screw.
Embodiment
Embodiments of the invention are described below in detail, the example of the embodiment is shown in the drawings.The embodiments described below with reference to the accompanying drawings are exemplary, is only used for explaining the present invention, and is not construed as limiting the claims.
Embodiment of the present invention：1st, arranged using spring external, compensation mechanism is not influenceed by slurry, ensures the stability of sealing operating；2nd, using hardness and wearability more preferably SSIC entirety end face, frictional heat is reduced, ensures relatively low PV values, effectively increases the service life；3rd, dynamic and static ring full-floating type design, using packaging type Flexible Transmission, the damage sealing of the factors such as startup-shutdown, vibration, play is avoided；4th, built-in self-lubricating bearing, influence of the stirring shaft deflection to sealing is reduced；5th, integrated form designs, easier for installation quick.6th, it is simple in construction, convenient disassembly.Before mechanical seal assembling, first bearing and bearing gland, inner sleeve are fitted together, then assembled again with axle sleeve, rotating ring, stationary ring etc..Because the process for assembling bearing is individually to assemble, so not interfering with the other parts of mechanical seal.
Embodiment one：As shown in drawings, mechanical seal main body educates bearing portions split design, while bearing portions combines to form cartridge seal with mechanical seal injection body part, and while accurate positioning is ensured, dismounting is again very convenient.The seal face of rotating ring 2 and stationary ring 3 fits.Spring 6 is installed between stationary ring 3 and seal receptacle 4; spring locating shaft 5 is installed between stationary ring 3 and spring 6; the one end of spring 6 fits with spring locating shaft 5; the other end is arranged in seal receptacle 4; stationary ring stop pin 8 is located at the side of stationary ring 2 and is provided with elastomer; played when transmitting moment of torsion and slow down effect, protection stationary ring 3 is unaffected, and seal is provided between stationary ring 3 and seal receptacle 4.Rotating ring 2 is sleeved on axle sleeve 1）On, and rotating ring stop pin 7 is connected between axle sleeve 1, rotating ring stop pin 7 is located at the side of rotating ring 2 and is provided with elastomer, is played when transmitting moment of torsion and slows down effect, and protection rotating ring 2 is unaffected, and seal is provided between rotating ring 2 and axle sleeve 1.Bearing inner sleeve 14, bearing 12 are connected with bearing gland 9 using small―gap suture, and lip is provided between bearing 12 and bearing gland 9 and seals 10 end rings 11, outside is spacing with jump ring 13.Bearing inner sleeve 14 is connected with axle sleeve 1 using positioning screw 20, and bearing inner sleeve 14 is connected with driving conical ring 16 using soket head cap screw 21, and seal receptacle 4 is connected with bearing gland 9 using soket head cap screw 17.Mechanical seal main body and the integrated of bearing portions are realized that driving is realized using jackscrew 19, driving conical ring 16 and soket head cap screw 21 by positioning screw 20, limit locking pieces 15, soket head cap screw 18.
The foregoing is only a preferred embodiment of the present invention, not makees any formal limitation to the present invention.The those of ordinary skill of all industry, can be shown in by specification accompanying drawing and described above, swimmingly implements the present invention.But all those skilled in the art, technical solution of the present invention scope is not being departed from, is being equivalent embodiment of the invention when the equivalent variations for a little variation, modification and evolution made using disclosed above technology contents；Meanwhile all variation, modification and evolution of any equivalent variations for being made to above example of substantial technological according to the present invention etc., still fall within the scope of technical scheme.
