Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, for the sealing system of malleation rotary kiln, comprise cylinder of rotary kiln 1, kiln hood fixed cover 2 and sealing device 3; Described sealing device 3 comprises steam seal structure 31; Described steam seal structure 31 comprises support ring flat-plate 311, banded support ring flat-plate 312, annular pressure pad 313, steam pipe 314 and steam providing apparatus; Supporting ring flat-plate 311, banded support ring flat-plate 312 and annular pressure pad 313 is generally all be made up of metal material; Described support ring flat-plate 311 and the banded ring flat-plate 312 that supports are fixedly mounted on cylinder of rotary kiln 1 and kiln hood fixed cover 2 respectively; Supporting ring flat-plate 311 is generally the flat part that inner ring and cylinder of rotary kiln 1 circumference match, and is usually weldingly fixed on cylinder of rotary kiln 1; The banded ring flat-plate 312 that supports is in banded annular support member, is usually weldingly fixed on kiln hood fixed cover 2; Described annular pressure pad 313 one end is fixed on banded support ring flat-plate 312, and the other end is attached to and supports on ring flat-plate 311; Annular pressure pad 313 can be all-in-one-piece loop configuration, also can be partly overlapped each other the loop configuration formed by multiple parts; Annular pressure pad 313, generally by screw or be bolted to and bandedly support on ring flat-plate 312, certainly also to be welded and fixed, can also be made into integral structure with support ring flat-plate 312; Annular pressure pad 313 can have many places with the bonding position supporting ring flat-plate 311, such as: be fitted in and support on the annular outer surface of ring flat-plate 311 or side surface, be preferably in Fig. 1, annular pressure pad 313 is fitted in and supports the laminating type of ring flat-plate 311 on the side surface of kiln hood fixed cover 2 side; Described support ring flat-plate 311, the banded ring flat-plate 312 and the inner surface of annular pressure pad 313 and the outer surface of cylinder of rotary kiln 1 and kiln hood fixed cover 2 of supporting surround vapor chamber 315; Vapor chamber 315, for storing steam, seals rotary kiln; Described steam pipe 314 one end is arranged on steam providing apparatus, and the other end is communicated with vapor chamber 315.Steam pipe 314 is normally communicated with vapor chamber 315 through banded support ring flat-plate 312.
In running: when not passing into steam seal, support ring flat-plate 311, banded support ring flat-plate 312 and annular pressure pad 313 and form conventional seals, make the sealing effectiveness of steam seal structure 31 general.In vapor chamber 315, steam is injected by steam providing apparatus; When passing into a small amount of steam, although the pressure in vapor chamber 315 is less than or equal to the pressure of cylinder of rotary kiln 1 inside, but vapor chamber 315 is less than the pressure differential of outside air and cylinder of rotary kiln 1 inside with the pressure differential of cylinder of rotary kiln 1 inside, and steam seal structure 31 sealing effectiveness obviously strengthens; When passing into steam and making the pressure in vapor chamber 315 be greater than the pressure of cylinder of rotary kiln 1 inside, rotary kiln runs under being in negative relative state; Rotary kiln is in negative relative state and namely refers to that the pressure in the corresponding vapor chamber 315 of the pressure of cylinder of rotary kiln 1 inside is negative pressure; Now, under the protection of steam, prevent outside air to enter cylinder of rotary kiln 1, the gas or the dust that avoid cylinder of rotary kiln 1 inside are revealed, and sealing effectiveness is good, and reliability is high; And a small amount of condensate liquid that steam-condensation is separated out can also play lubrication.
As a kind of preferred version of the present utility model, described sealing device 3 also comprises the labyrinth seal structure 32 being arranged in vapor chamber 315; Described labyrinth seal structure 32 comprises the first labyrinth ring 321 be arranged on cylinder of rotary kiln 1 and the second labyrinth ring 322 be arranged on kiln hood fixed cover 2, described first labyrinth ring 321 and the second labyrinth ring 322 mutually embed overlappingly at least partly and can relatively rotate with respect to each other, as shown in Figure 1.The annular element of the first labyrinth ring 321 and the normally multiple annular composition of the second labyrinth ring 322, first labyrinth ring 321 and the second labyrinth ring 322 embed mutually, form the annular section or all overlapping of the first labyrinth ring 321 and the second labyrinth ring 322, and the first labyrinth ring 321 and the second labyrinth ring 322 can relatively rotate.Labyrinth seal structure 32 further increases sealing effectiveness, simultaneously cylinder of rotary kiln 1 expand, circular runout or axial float time labyrinth seal structure 32 influenced less, sealing reliability is higher.
Consider that the dust of cylinder of rotary kiln 1 inside may be leaked by the gap in labyrinth seal structure 32, in the gap between described first labyrinth ring 321 and the second labyrinth ring 322, be provided with airtight and watertight padding 323.Airtight and watertight padding 323 also has certain lubricant effect.
On the basis of the above, in order to improve sealing effectiveness again, described sealing device 3 also comprises the pressure pad sealing ring 33 being arranged in vapor chamber 315, described pressure pad sealing ring 33 is arranged on the outside of labyrinth seal structure 32, one end of pressure pad sealing ring 33 is fixed on kiln hood fixed cover 2, and the other end of pressure pad sealing ring 33 is attached on the annular surface of the most outer shroud of the first labyrinth ring 321.Pressure pad sealing ring 33 can be all-in-one-piece loop configuration, also can be the loop configuration become by multiple assembling parts; Pressure pad sealing ring 33 is generally fixedly mounted on kiln hood fixed cover 2 by screw.Concrete, one end that described pressure pad sealing ring 33 is attached to the first labyrinth ring 321 is cross section is lambdoid laminating end 331.Lambdoid laminating end 331 has certain elasticity, can absorb the radial direction of cylinder of rotary kiln 1, longitudinal dilatation and circular runout.
