Abstract
A head and tail sealing device for a rotary kiln comprises a plurality of sealing blocks I and sealing blocks II, wherein the sealing blocks I and the sealing blocks II are mutually connected. Each of the sealing blocks I and the sealing blocks II comprises an elastic sheet and a wheel mounting block arranged at one end of the inner side of the elastic sheet. The wheel mounting blocks are provided with rectangular grooves inside, and bidirectional wheels are mounted in the rectangular grooves. The head and tail sealing device for the rotary kiln further comprises a plurality of fixed blocks fixed on the back of the elastic sheets. The head and the tail of the rotary kiln are sealed by the aid of the sealing blocks with the flexible bidirectional wheels, and the requirement for sealing under the condition of complicated motions such as rotation, swing and axial runout of the rotary kiln can still be met, air seepage and dust leakage coefficients are decreased, and energy resources are indirectly saved. Meanwhile, original sliding friction is changed into rolling friction, friction loss is reduced, and service life of the sealing device is prolonged.
Description
Technical field
The utility model relates to seal of rotary kiln technical field, is specifically related to a kind of rotary kiln end kiln tail sealing device.
Background technology
In cement manufacture plant, the sealing of rotary kiln end, kiln tail is extremely important, if kiln hood, kiln tail seal bad, can strengthen the load of high-temperature blower and tail exhaust blower, not only cause the waste of coal electricity, in rotary kiln, also can produce malleation and make combustion instability, the too high kiln head cover top that even burns out of temperature of kiln head.A large amount of entering of cold wind have been strengthened hear rate, have wasted coal electricity, bring hidden danger to clinker quality; A large amount of hot flying dust splash everywhere, have greatly affected safety in production and environmental protection.
The sealing device of rotary kiln end, kiln tail, adapt to the process environments of high temperature, high dust, negative pressure, at present, what generally adopt is the sealing means of flap, but there is the compound movements such as revolution, swing and axial float due to cylinder of rotary kiln, between pivoting part and fixed part, have the radial and axial gap constantly changing, the sealing means of flap exists and leaks out, leaks grey technical problem, can not meet the requirement of production technology.
Utility model content
Adopt the sealing means of flap to exist in order to solve the kiln hood, kiln tail of rotary kiln in prior art and leak out, leak grey technical problem, the purpose of this utility model is to provide a kind of flexible bidirectional rolling type kiln head and tail sealing device that adopts, sealing device can adapt to the kiln head and tail sealing under the complicated operating condition of rotary kiln, has reduced to leak out, leaked grey coefficient.
To achieve these goals, the utility model has adopted following technical scheme:
A kind of rotary kiln end kiln tail sealing device, comprise the interconnective sealing block I of polylith and sealing block II, described sealing block I and sealing block II comprise flexure strip and are arranged on the roller mounting blocks of flexure strip inner face one end, in described roller mounting blocks, be provided with rectangular channel, two-way roller is installed in rectangular channel; Described rotary kiln end kiln tail sealing device also comprises the multiple fixed blocks that are fixedly installed on the flexure strip back side.
Further, the width of the flexure strip of described sealing block II is greater than the width of roller mounting blocks, and the flexure strip of sealing block II is overlapped in the flexure strip of sealing block I.
Further, be also disposed with one deck elevated-temperature seal felt and one deck fish scale diaphragm seal at the described flexure strip back side, described fixed block is fixedly installed on fish scale diaphragm seal.
Further, between described sealing block I and sealing block II, by bolt and nut, flexure strip is fixedly connected with.
Further, described fixed block is fixed on fish scale diaphragm seal by bolt and nut.
Useful technique effect of the present utility model is:
The sealing device of rotary kiln end kiln tail of the present utility model, adopt and with the sealing block of the two-way roller of flexibility, rotary kiln end kiln tail is sealed, the in the situation that of there is the compound movements such as revolution, swing and axial float at cylinder of rotary kiln, still can meet seal request, reduced to leak out, leaked grey coefficient, indirect saving the energy; The sealing device of rotary kiln end kiln tail of the present utility model adopts flexible bidirectional rolling type sealing simultaneously, original sliding friction is become to rolling friction, reduce frictional dissipation, increased sealing device service life, in prior art, the service life of fish scale strip type seals is generally in 1-2 years, and can bring up to more than 5 years the service life of the sealing device of rotary kiln end kiln tail of the present utility model, reduce the cost of maintenance of equipment; Meanwhile, the sealing device structure of rotary kiln end kiln tail of the present utility model is simple, it is easy for installation to process, and cost is low.
