Abstract
The invention belongs to the field of mechanical seal, and particularly relates to a multi-purpose type packaging double-end-face sealing device for an agitated vessel top. The multi-purpose type packaging double-end-face sealing device comprises a bearing part and a sealing part. The multi-purpose type packaging double-end-face sealing device is characterized in that the bearing part is used for achieving synchronization of a bearing and the sealing device; the sealing part is used for sealing a gap between a vessel shaft and a vessel. The multi-purpose type packaging double-end-face sealing device for the agitated vessel top has the advantages of being complete in performance, low in cost, convenient to operate and maintain, safe, reliable and capable of completely solving the problem that a traditional mechanical sealing device for a vessel is inconvenient to assemble, difficult to replace and unstable in service life. Practices have proved that the multi-purpose type packaging double-end-face sealing device can be used for production and scientific experiments of industries such as chemical engineering, medicine and foods, and is completely feasible in the technique, the economy and the environmental protection.
Description
Technical field
The invention belongs to mechanical seal field, particularly relate to multi-purpose type stirred tank still very useful unit loading type double seals device.
Background technique
Mechanical sealing element technology is widely used in the fields such as national defence, electric power, chemical industry, oil, metallurgy, communications and transportation, medicine, food, cosmetics, the application of multi-purpose type stirred tank still very useful unit loading type double seals device is an importance in mechanical seal field, belongs to a kind of unit loading type still seal arrangement.Vesselseals traditional both at home and abroad can not meet the needs of polytypic sealing configuration, and traditional vesselseals axially locating deviation easily occurs, the problems such as it is improper to assemble, and Packing spring power is uneven simultaneously, causes working life unstable, and changes not easily.Multi-purpose type stirred tank still very useful unit loading type double seals device overcomes the shortcoming of traditional mechanical sealing device for cauldron, spring is shared by Double End, adopt bearing inside and outside delineation position assembling mode and design independent bearing outside for bearing assemble, and innovation sealing-locking device, problems such as solving traditional vesselseals assembling inconvenience, change difficulty, working life is unstable, improve manufacturing efficiency, provide cost savings, ensured the safety of product, the prodution and development for chemical industry, medicine and food provides facility and ensures.
Summary of the invention
Main purpose of the present invention is the deficiency overcoming above-mentioned technology, and provides multi-purpose type stirred tank still very useful unit loading type double seals device.This device may be used for being tightly connected of still axle and still in the Industry Manufacturing Equipment such as chemical industry, medicine and food, technically, economically with environmental protection is all feasible.
The present invention for achieving the above object, by the following technical solutions: multi-purpose type stirred tank still very useful unit loading type double seals device, comprises bearing part and hermetic unit.It is characterized in that: described bearing part, for realizing the synchronous of bearing and seal arrangement; Described hermetic unit, for the sealing in gap between still axle and still.
Beneficial effect: multi-purpose type stirred tank still very useful unit loading type double seals device performance is perfect, cost is low, convenient operating maintenance, safe and reliable.Because the industries such as chemical industry, medicine and food are for the free of contamination strict demand of material in production process, utilize multi-purpose type stirred tank still very useful unit loading type double seals device, traditional mechanical sealing device for cauldron assembling inconvenience can be solved completely, change difficult, that working life is unstable problem.Facts have proved, this device may be used for industry production and the scientific experiments such as chemical industry, medicine and food, technically, economically with environmental protection is all feasible.Have the following advantages:
1. design of the present invention, adopt Double End to share spring structure, upper and lower dynamic and static ring is equal to, and can carry out static pressure test under bearing-free partial picture, decreases the sealing assembling test time, highly effective and safe, saves financial cost.
2. design of the present invention, adopt bearing inside and outside delineation position assembling mode, it is improper to avoid owing to assembling, and causes Packing spring power uneven, improves the working life of sealing.
3. design of the present invention, adopt independent bearing outside trim designs, the polytype bearing of easy replacing, as deep groove ball bearing, angular contact bearing, selfaligning bearing, tapered roller bearing etc., the support situation of multiple still axle can be adapted to, solve the sealing of still top and can only use single bearing type, the situation that bearing type must change seal casinghousing be changed, be convenient to install and change.
4. the locking device of the present invention's design adopts band to lengthen the lower lock collar of cover, is connected to bearing inner sleeve locates with screw thread and axle sleeve, is convenient to bearing location and sealing locking.
5. design of the present invention, is applicable to subzero 60 degrees Celsius to 300 degrees Celsius, vacuum-2.5Mpa pressure, rotating speed is maximum reaches 500r.p.m.
Accompanying drawing explanation
Accompanying drawing is structural drawing of the present invention, 1 independent bearing outside, and 2 utilize the inside and outside circle location and installation sealing of bearing, 3 threaded connection places, and 4 utilize the inside and outside circle location and installation sealing of bearing, and 5 share springs, the lower lock collar in 6 sealing-locking devices.
Embodiment
The specific embodiment of the present invention is described in detail below in conjunction with accompanying drawing and preferred embodiment.Its structural drawing is as shown in Figure of description.Multi-purpose type stirred tank still very useful unit loading type double seals device, comprises bearing part and hermetic unit.Described bearing part, for realizing the synchronous of bearing and seal arrangement, utilizing the inside and outside circle location and installation sealing 2 and 4 of bearing, adopting independent bearing outside 1 trim designs simultaneously; Described hermetic unit, for the sealing in gap between still axle and still, adopts Double End to share spring 5 structure, utilizes the lower lock collar 6 in sealing-locking device, be threaded connection place 3, positioning bearing part and hermetic unit.
The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the premise without departing from the principles of the invention; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
