Description
Technical field
This utility model relates to mechanically-sealing apparatus field, particularly relates to a kind of Double End integrated mechanical sealing device.
Background technology
nullAt present，In the slurry medium that concentration is higher (slurry concentration reaches more than 60%)，General mechanical seal is difficult to meet and uses requirement，Higher because of concentration of medium in the course of the work，Mechanical seal easily blocks，Mechanical seal is caused to be lost efficacy，Simultaneously,Mechanical seal runs in the medium that concentration of medium is higher，Machine's sealing is the fastest，The speed that mechanical seal was lost efficacy is accelerated,It is typically less than one month and just lost efficacy，Production requirement cannot be met，Greatly reduce production efficiency,In order to solve this problem,The general equipment that (slurry concentration reaches more than 60%) uses in the slurry medium that concentration is higher，All use packing seal，But packing seal is easy to leakage，Affect environmental protection，The replacement frequency of filler is the highest，Within general several days, it is accomplished by changing once，Bother very much，Have a strong impact on production，Reduce production efficiency.
Utility model content
This utility model provides a kind of Double End integrated mechanical sealing device, it is therefore an objective to for solving the problems of the prior art, it is provided that the Double End integrated mechanical sealing device that a kind of service life is long, quick and easy for installation.
The technical solution of the utility model is:
A kind of Double End integrated mechanical sealing device, it is characterized in that: there is axle sleeve, seal receptacle it is arranged with outside axle sleeve, space is had between seal receptacle and axle sleeve, space between seal receptacle and axle sleeve is sequentially provided with media end rotating ring from left to right, media end stationary ring, atmosphere end stationary ring, the right side of the outer atmosphere end stationary ring of axle sleeve is arranged with atmosphere end rotating ring, driving ring it is arranged with outside atmosphere end rotating ring, ring is driven to be connected by screw and atmosphere end rotating ring are fixing, the surface that described media end rotating ring contacts with seal receptacle is provided with helicla flute, gap it is provided with between helicla flute and seal receptacle, helicla flute connects with medium.
Described media end rotating ring, media end stationary ring and seal receptacle surround lubricating cavity, fill up grease in lubricating cavity, media end rotating ring, are connected and sealed by grease between media end stationary ring and seal receptacle.
It is provided with sealing ring between described seal receptacle and media end stationary ring.
It is provided with sealing ring between described seal receptacle and atmosphere end stationary ring.
It is provided with sealing ring between described axle sleeve and media end rotating ring.
It is provided with sealing ring between described axle sleeve and atmosphere end rotating ring.
The beneficial effects of the utility model: owing to media end rotating ring excircle is provided with helicla flute, helicla flute on media end rotating ring excircle produces and pressure medium opposite effect power, both active force basic neutralisations, medium will not flow to media end rotating ring and media end stationary ring, media end rotating ring does not contacts with medium with media end stationary ring, therefore, work under conditions of media end rotating ring and media end stationary ring are just relatively clean at one, the service life of mechanically-sealing apparatus can be greatly prolonged, decrease the frequency changing mechanical seal, the utilization rate making mechanical seal reaches to maximize, save production cost.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
nullSuch as Fig. 1、A kind of Double End integrated mechanical sealing device shown in Fig. 2，There is axle sleeve 1，Seal receptacle 2 it is arranged with outside axle sleeve 1，Space is had between seal receptacle 2 and axle sleeve 1，Space between seal receptacle 2 and axle sleeve 1 is sequentially provided with media end rotating ring 3 from left to right、Media end stationary ring 4、Atmosphere end stationary ring 5，The right side of the outside atmosphere end stationary ring 5 of axle sleeve 1 is arranged with atmosphere end rotating ring 6，Driving ring 7 it is arranged with outside atmosphere end rotating ring 6，Ring 7 is driven to be connected by screw 8 is fixing with atmosphere end rotating ring 6，The surface that described media end rotating ring 3 contacts with seal receptacle 2 is provided with helicla flute 9，It is provided with gap between helicla flute 9 and seal receptacle 2，Helicla flute 9 connects with medium，Described media end rotating ring 3、Media end stationary ring 4 and seal receptacle 2 surround lubricating cavity 10，Grease 11 is filled up in lubricating cavity 10，Media end rotating ring 3、It is connected and sealed by grease 11 between media end stationary ring 4 and seal receptacle 5.
Between described seal receptacle 2 and media end stationary ring 4, between seal receptacle 2 and atmosphere end stationary ring 5, between axle sleeve 1 and media end rotating ring 3, between axle sleeve 1 and atmosphere end rotating ring 6, it is equipped with sealing ring 12.
nullIn the course of the work，Axle sleeve 1 rotarily drives media end rotating ring 3 and rotates，Owing to media end rotating ring 3 excircle is provided with helicla flute 9，Helicla flute 9 on media end rotating ring 3 excircle produces and pressure medium opposite effect power，Both active force basic neutralisations，Medium will not flow to media end rotating ring 3 and media end stationary ring 4，Media end rotating ring 3 does not contacts with medium with media end stationary ring 4，Therefore，Work under conditions of media end rotating ring 3 and media end stationary ring 4 are just relatively clean at one，The service life of mechanically-sealing apparatus can be greatly prolonged，Simultaneously，Media end rotating ring 3、It is connected and sealed by grease 11 between media end stationary ring 4 and seal receptacle 5 and can not only reach better seal effect，Intercept medium and flow to media end stationary ring 4 from media end rotating ring 3，And can also good lubricating screw groove 9、Media end rotating ring 3 and media end stationary ring 4，Reduce the frictional dissipation between each parts，Decrease the frequency changing mechanical seal，The utilization rate making mechanical seal reaches to maximize，Save production cost.
Owing to media end rotating ring 3 and seal receptacle 2 all have employed high abrasion corrosion-resistant material, the service life of this mechanical seal can be the longest, General Life can reach half a year more than, and well solving mechanical seal can not (slurry concentration reaches more than 60%) uses in the slurry medium that concentration is higher problem.This mechanically-sealing apparatus also can run (double mechanical seal cooling effect is preferable) under higher temperature and pressure, and packaging type structure design and installation is also convenient for fast.
