The rotary kiln and the combined sealing device thereof not only ensure the normal sealing of the rotary kiln, but also have a better sealing function under the condition that the processing and manufacturing precision of the sealing device can not achieve a requirement, the losing, assembling and installing precision of the sealing material can not achieve the requirement; and the sealing effect is more effective and reliable than the ordinary sealing way.
Description
Technical field
The utility model relates to a kind of mechanically-sealing apparatus, more particularly, relates to a kind of combination sealing arrangement that is installed on the rotary kiln.
Background technology
At present, known sealing means generally has the sealing means such as packing ring, pad, filler, machinery, labyrinth, centrifugal, screw thread, pneumatic, waterpower, the sealing of these sealing devices when static by seal is more effective, and in case when dynamic part is sealed, these sealing devices are just very unreliable.Especially when needs to poisonous, harmful, inflammable, when explosion hazard gases seals, because the impact of the factors such as processing and manufacturing precision, seal material quality, assembling, installation accuracy, be difficult to accomplish positiver sealing, perhaps work long-time after, parts are impaired, must cause seal failure, sealed thing just may leak.
The utility model content
For deficiency of the prior art, one of the purpose of this utility model is to solve the one or more problems that exist in the above-mentioned prior art.
Of the present utility modelly provide a kind of combination sealing arrangement with good seal performance, the sealing device can be realized the normal sealing to gas in the rotary kiln, can realize again the excellent sealing to rotary kiln under abnormal condition.
To achieve these goals, the utility model provides combination sealing arrangement on a kind of rotary kiln on the one hand, and described combination sealing arrangement comprises: the rotating ring that is fixed on the rotary body of rotary kiln and rotates with rotary body; Be fixed on the stationary ring on the rotary kiln standing part, the end face of this stationary ring and the end face of this rotating ring seal applying each other, to form sealing surface; Be arranged on gas storage groove on the described sealing surface along the whole circumferencial direction of rotary body; Be communicated with described gas storage groove with in described gas storage groove, feed pressure more than or equal to rotary kiln in the air inlet of pressure of gas.
When rotary kiln runs well, by being sealed and matched of rotating ring and stationary ring, realized the normal sealing to gas in the rotary kiln, and pass into gas in the gas storage groove on the sealing surface between rotating ring and stationary ring, make gas pressure in this gas storage groove more than or equal to the pressure of gas in the rotary kiln, to further play sealing function, remedy the leakage that rotating ring and stationary ring end face seal may occur, guarantee the sealing of rotary kiln.
According to an embodiment of rotary kiln combination sealing arrangement of the present utility model, described air inlet is arranged on the described stationary ring.
According to an embodiment of rotary kiln combination sealing arrangement of the present utility model, the sealing surface of described gas storage groove between described rotating ring and stationary ring is annular.
According to an embodiment of rotary kiln combination sealing arrangement of the present utility model, described gas storage groove is positioned on the end face of described stationary ring.
Of the present utility modelly provide on the other hand a kind of rotary kiln, comprised rotary body and standing part, described rotary kiln also comprises aforesaid combination sealing arrangement.
Compared with prior art, the utility model had both guaranteed the normal sealing of rotary kiln, again can be at sealing device because the processing and manufacturing precision does not reach requirement, the strain of encapsulant material, assembling, installation accuracy does not reach in the situation of requirement, also can obtain preferably sealing effectiveness.

Description of reference numerals:
The rotary body of 1-rotating ring, 2-stationary ring, 3-gas storage groove, 4-air inlet, 5-rotary kiln, 6-rotary kiln standing part.
The specific embodiment
Hereinafter, in connection with accompanying drawing exemplary embodiment of the present utility model is described in further detail.
Fig. 1 is the cutaway view of the rotary kiln combination sealing arrangement of the utility model exemplary embodiment.Fig. 2 is the schematic diagram in A-A cross section of the rotary kiln combination sealing arrangement of the utility model exemplary embodiment.As depicted in figs. 1 and 2, the rotating ring 1 that the combination sealing arrangement of present embodiment comprises on the rotary body 5 that is fixed on rotary kiln and rotates with rotary body 5, be fixed on the stationary ring 2 on the rotary kiln standing part 6, the end face of the end face of this rotating ring 1 and this stationary ring 2 is sealed and matched each other, the seal face formation sealing surface that is fitted to each other; Sealing surface between described rotating ring 1 and stationary ring 2 is provided with the gas storage groove 3 along whole circumferential extension, certainly, this gas storage groove both can be arranged on the end face that is positioned at this stationary ring 2, can be arranged on again on the end face that is positioned at this rotating ring 1, namely as long as gas storage groove along the whole circumferencial direction of rotary body of the formation of the sealing surface between this rotating ring 1 and stationary ring 2 can, wherein, this gas storage groove can be the shape of any closure, as long as be provided with the whole circumferencial direction extension along rotary body on the sealing surface between described rotating ring 1 and the stationary ring 2, preferably, the sealing surface of described gas storage groove 3 between described rotating ring 1 and stationary ring 2 is annular, because annular is convenient to processing, and gas uniform is distributed.
Because during work, this rotating ring 1 is along with rotary body 5 rotations, and this stationary ring 2 is fixed on the rotary kiln, so preferably air inlet 4 is arranged on this stationary ring 2, by air inlet 4, with inert gas or other not with equipment in the gas that reacts of material pass in the described gas storage groove 3, pass into the pressure of gas more than or equal to gas pressure in the equipment.
During rotary kiln work, rotating ring 1 on the sealing device is along with the rotary body rotation of rotary kiln, and the rotary kiln standing part 6 that stationary ring 2 is fixed as one with it keeps maintaining static, rotating ring 1 and the stationary ring 2 of this combination sealing arrangement are sealed and matched each other, and gas in this rotary kiln device is normally sealed.
If because processing and manufacturing, installation, the assembly precision of this rotating ring 1 or stationary ring 2 are inadequate, gas may leak in the rotary kiln device, at this moment, except rotating ring 1 and stationary ring 2 be sealed and matched seal, gas in the gas storage groove on the sealing surface between rotating ring and stationary ring will play further sealing function, remedy the leakage that rotating ring 1, stationary ring 2 end face seals may occur, guarantee that gas can not leak in the rotary kiln device, reach reliable sealing effectiveness.
In sum, rotary kiln combination sealing arrangement of the present utility model is simple in structure, easy to manufacture, practical, compare with existing various sealing devices, and be a kind of combination sealing arrangement that integrates mechanical end face seal and air seal; By combination sealing arrangement of the present utility model is installed, not only can further strengthen the sealing of rotary kiln, and work as sealing device owing to processing and manufacturing, erection precision are inadequate, and the Leakage Gas situation that sealing device is long-time may to be occurred after using can play preferably sealing effectiveness to rotary kiln when occurring too.
Although the above illustrates and has described rotary kiln combination sealing arrangement of the present utility model in conjunction with the embodiments, but what those skilled in the art will appreciate that is, in the situation that does not break away from the spirit and scope of the present utility model that limit such as claims, can make the various changes on form and the details here.
