Technical field
The utility model relates to a kind of sealing device, is specifically related to a kind of seal of rotary kiln device.
Background technology
Rotary kiln is the capital equipment that the industries such as metallurgy, chemical industry and cement heat loose unpacked material.Cylinder of rotary kiln is rotary part, in itself and rotary kiln fixed part connection between inevitably there is gap, carrying material to stop the extraneous air gas be inhaled in cylinder of rotary kiln or in cylinder of rotary kiln to leak, hermetically-sealed construction must be set between cylinder of rotary kiln and the connection of fixed part and seal.
Traditional seal of rotary kiln device mainly comprises fish scale lamellar seal, labyrinth sealing, fish scale chip and labyrinth type combination sealing.But these hermetically-sealed constructions all need multiple parts to form, complex structure, installing engineering amount are large, and maintenance rate is higher, sealing effectiveness general, there is problems such as leaking ash, leak out, are unfavorable for the stable operation of rotary kiln.
Utility model content
The technical problems to be solved in the utility model is to provide the simple and good a kind of seal of rotary kiln device of sealing effectiveness of a kind of structure.
In order to solve the problems of the technologies described above, the utility model provides a kind of seal of rotary kiln device, comprises cylinder of rotary kiln, intermediate seal ring and kiln head cover; Described intermediate seal ring is arranged on cylinder of rotary kiln, and the outer surface of intermediate seal ring is provided with outer groove; The cover mouth of described kiln head cover is provided with annular insert plate, and described annular insert plate embeds in outer groove and cylinder of rotary kiln and kiln head cover are sealed connected together, and cylinder of rotary kiln can move relative to kiln head cover; Described annular insert plate is matched in clearance with coordinating between outer groove, and annular insert plate is provided with at least one oil filler point, and described oil filler point makes outer groove be in communication with the outside.
Further, the cylinder of rotary kiln outer wall between described cylinder of rotary kiln and intermediate seal ring is provided with annular friction cover.
Further, described intermediate seal ring is movably arranged on cylinder of rotary kiln, and the inner surface of intermediate seal ring is provided with inner groove, and the inside of intermediate seal ring is also provided with at least one oilhole being communicated with outer groove and inner groove.
Further, described oilhole is two or more, and uniform ringwise along the circumference of intermediate seal ring.
Further, described oilhole is straight hole, and arranges along the radial direction of intermediate seal ring.
Further, described oil filler point is two, and is symmetricly set on the both sides up and down of annular insert plate.
The beneficial effects of the utility model are: sealed by set intermediate seal ring and annular insert plate, seal member is less, and structure is simple; Annular insert plate embeds outer groove and connects, and in outer groove, injects lubricating oil by oil filler point, makes this structure have better sealing effectiveness, also reduces friction simultaneously.Annular friction cover can protect cylinder of rotary kiln, avoids it to wear and tear.When the activity of intermediate seal ring is installed, lubricating oil enters in inner groove the sealing effectiveness improved further between this intermediate seal ring and cylinder of rotary kiln from oilhole, also can reduce friction simultaneously, can also prevent cylinder of rotary kiln expansion, circular runout or axial float from hermetically-sealed construction was lost efficacy, improve the service life of hermetically-sealed construction.The utility model structure is simply convenient to processing and manufacturing, transport, installation, and later maintenance cost is low, and rotary kiln running is stablized, and is suitable for applying.
Accompanying drawing explanation
Fig. 1 is enforcement structural representation of the present utility model;
Be labeled as in figure: cylinder of rotary kiln 1, intermediate seal ring 2, outer groove 21, inner groove 22, oilhole 23, kiln head cover 3, annular insert plate 31 and oil filler point 311.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, a kind of seal of rotary kiln device, comprises cylinder of rotary kiln 1, intermediate seal ring 2 and kiln head cover 3; Described intermediate seal ring 2 is arranged on cylinder of rotary kiln 1, and the outer surface of intermediate seal ring 2 is provided with outer groove 21; Intermediate seal ring 2 is the annular seal part matched with cylinder of rotary kiln 1; Intermediate seal ring 2 can be fixedly installed on cylinder of rotary kiln 1, also can be movably arranged on cylinder of rotary kiln 1, and movable setting refers to that intermediate seal ring 2 can rotate or slide axially on cylinder of rotary kiln 1; Outer groove 21 is the annular grooves being positioned at intermediate seal ring 2 outer surface; The cover mouth of described kiln head cover 3 is provided with annular insert plate 31, and described annular insert plate 31 embeds in outer groove 21 and cylinder of rotary kiln 1 and kiln head cover 3 are sealed connected together, and cylinder of rotary kiln 1 can move relative to kiln head cover 3; In order to make kiln head cover 3 can move relative to cylinder of rotary kiln 1, intermediate seal ring 2 can be made to be movably arranged on cylinder of rotary kiln 1 or to make annular insert plate 31 be matched in clearance with outer groove 21, also can implementing simultaneously; Described annular insert plate 31 is matched in clearance with coordinating between outer groove 21, and annular insert plate 31 is provided with at least one oil filler point 311, and described oil filler point 311 makes outer groove 21 be in communication with the outside.During sealing, generally from oil filler point 311, in outer groove 21, inject lubricating oil, namely improve sealing effectiveness, also reduce the friction between annular insert plate 31 and intermediate seal ring 2 simultaneously.The annular inner portion of annular insert plate 31 is embedded in the outer groove 21 of intermediate seal ring 2 and forms sealing; Be matched in clearance between annular insert plate 31 and outer groove 21, namely annular insert plate 31 can rotate or axially-movable relative to intermediate seal ring 2.
In order to protect the outer wall of cylinder of rotary kiln 1, avoid itself and intermediate seal ring 2 to rub impaired, cylinder of rotary kiln 1 outer wall between described cylinder of rotary kiln 1 and intermediate seal ring 2 is provided with annular friction and overlaps 11.
On the basis of the above, in order to improve the sealing effectiveness of sealing structure further, described intermediate seal ring 2 is movably arranged on cylinder of rotary kiln 1, and the inner surface of intermediate seal ring 2 is provided with inner groove 22, the inside of intermediate seal ring 2 is also provided with at least one oilhole 23 being communicated with outer groove 21 and inner groove 22, as shown in Figure 1.Intermediate seal ring 2 activity is installed and is referred to that intermediate seal ring 2 can rotate or slide axially on cylinder of rotary kiln 1.Lubricating oil is set like this and can enters inner groove 22 from oilhole 23 sealing effectiveness improved further between intermediate seal ring 2 and cylinder of rotary kiln 1, also can reduce the friction between them simultaneously, but also can prevent that cylinder of rotary kiln 1 from expanding, circular runout or axial float make hermetically-sealed construction lose efficacy, and improves the service life of hermetically-sealed construction.
Enter in inner groove 22 for the ease of lubricating oil and be evenly distributed, to reach sealing and lubricant effect preferably, described oilhole 23 is two or more, and uniform ringwise along the circumference of intermediate seal ring 2.
