Abstract
The utility model relates to a mechanical seal for a dry run kettle. The mechanical seal comprises a flange fixing plate, wherein a rotating shaft is arranged in the middle of the flange fixing plate; a static ring is arranged between the flange fixing plate and the rotating shaft; a moving ring is arranged at the top of the static ring; a moving ring assembly is arranged at the outer side of the moving ring; a strutting piece assembly is arranged above the moving ring assembly; a spring is arranged between the moving ring assembly and the strutting piece assembly; the strutting piece assembly and a strutting piece above the strutting piece assembly are fixedly connected through screws; a fixing ring is arranged at the top end of the strutting piece; a sealing ring is arranged at the position, close to the rotating shaft, of the moving ring and the strutting piece. After the structure is adopted, a cooling jacket and a bearing are omitted, liquid such as water or oil cannot enter the mechanical seal to pollute materials, the size is small, the weight is lightened, and the carry by operators is facilitated.
Description
Technical field
The utility model relates to a kind of mechanical seal, especially relates to a kind of dry operation vesselseals that is applied to glassed steel reaction vessels.
Background technique
At present, glassed steel reaction vessels is by the glass containing high silicon dioxide in the prior art, lining is at the internal surface of Steel Vessel, through high temperature sintering and securely adherence becomes composite product on metal surface, it has the stability of glass and the two-fold advantage of metal strength, it is a kind of good corrosion resistant apparatus, existing vesselseals is all with cooling jacket and bearing, to pass into cold water and reach cooling effect in cooling jacket, and bearing must add lubricant oil, so just have an opportunity to the material contamination in reactor, and this mechanical seal volume and weight is all very large, be inconvenient to carry.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of dry operation vesselseals, and it does not have cooling jacket and bearing, can not add the little convenient carrying of unnecessary material contaminated materials and volume.
The technical scheme in the invention for solving the technical problem is: a kind of dry operation vesselseals, comprise flange plate, the centre of flange plate is provided with rotating shaft, be provided with stationary ring between described flange plate and rotating shaft, top at stationary ring is provided with rotating ring, the outside at rotating ring is provided with moving ring assembly, be provided with support body assembly above moving ring assembly, be provided with spring between moving ring assembly and support body assembly, support body assembly is connected by screw fastening with supporting element above it, on the top of supporting element, is provided with retaining ring; Position in rotating ring and the close rotating shaft of support body assembly is provided with seal ring.
In order further to make mechanical seal reach better sealing effect, be provided with O type circle between described stationary ring and seal ring; Be provided with O type circle between described seal ring and rotating shaft.
Fastening in order conveniently mechanical seal to be carried out, described supporting element is provided with fixed plate, and fixed plate is connected with flange plate by screw.
In order to facilitate the handling machinery sealing, described flange plate is provided with hanging ring.
The beneficial effects of the utility model are: after having adopted said structure, because removed cooling jacket and bearing, not there will be the liquid of water or an oily class to enter the mechanical seal contaminated materials, and smaller volume, weight lightens, easy-to-operat personnel's carrying.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1, stationary ring; 2, rotating ring; 3, flange plate; 4, hanging ring; 5, moving ring assembly; 6, seal ring; 7, support body assembly; 8, supporting element; 9, fixed plate; 10, retaining ring; 11, rotating shaft; 12, spring.
Embodiment
A kind of dry operation vesselseals as shown in Figure 1, comprise flange plate 3, the centre of flange plate 3 is provided with rotating shaft 11, be provided with stationary ring 1 between described flange plate 3 and rotating shaft 11, be provided with rotating ring 2 at the top of stationary ring 1, be provided with moving ring assembly 5 in the outside of rotating ring 2, be provided with support body assembly 7 above moving ring assembly 5, be provided with spring 12 between moving ring assembly 5 and support body assembly 7, support body assembly 7 is connected by screw fastening with supporting element 8 above it, on the top of supporting element 8, is provided with retaining ring 10; Be provided with seal ring 6 in rotating ring 2 and the position of support body assembly 7 close rotating shafts 11; Be provided with O type circle between described stationary ring 1 and seal ring 6; Be provided with O type circle between described seal ring 6 and rotating shaft 11; Sealing effect is better; Described supporting element 8 is provided with fixed plate 9, and fixed plate 9 is connected with flange plate 3 by screw; Described flange plate 3 is provided with hanging ring 4, and the easy-to-operat personnel carry the lifting reactor.
This kind of sealing when in use, contacts as the dry grinding type, without cooling jacket and bearing, is applicable to very much glassed steel reaction vessels and uses, and running efficiency is high, pollutes little.
It is emphasized that above is better implementation column of the present utility model, and any simple modification, equivalent variations and modification that every foundation technical spirit of the present utility model is done above embodiment, all still belong in the scope of technical solutions of the utility model.
