Description
Technical field
The utility model relates to high temperature rotating kiln technical field of sealing technology, and especially a kind of high temperature huge revolving kiln controls sealing device automatically.
Background technology
Huge revolving kiln is when hot operation, body of heater rotates, input and output material fixed enclosure transfixion, in prior art, the sealing of this type high temp major diameter sealing device adopts two profiles formula: one is annular friction sheet press seal, friction plate selects graphite block usually, friction plate is in the process of running relatively, be easy to cause wearing and tearing, make service life reduction, simultaneously, the sealing effectiveness of sealing device in order to reach, usual employing minor diameter sealing realizes, and these factors cause sealing device to have significant limitation, and sealing effectiveness is undesirable; But adopting the sealing of scale cluster, easily wearing and tearing kiln main body, when kiln internal gas pressure is too high, sealing effectiveness is poor.Therefore, a kind of without limitation, the device that can meet the sealing of major diameter high temperature kiln cylindrical shell in the urgent need to developing, ensure sealing.
Through retrieval, application number be 201320278616.6 patent document disclose a kind of cylinder end sealing device of rotary kiln, adopt contact type sealing device, the sealing that can it be kept in Long-Time Service perfect, but higher to the material requirements of friction part, serious wear, maintenance is frequent, axial contact seal structure complex, inconvenient maintenance; Radial contact seal structure is simple, easy to maintenance, but quick abrasion, affect sealing effectiveness.
In view of the foregoing, the structure of existing kiln sealing device needs to improve.
Utility model content
The purpose of this utility model is to overcome deficiency of the prior art, a kind of high temperature huge revolving kiln is provided automatically to control sealing device, end face is adopted to compress mazy encapsulating method, major diameter kiln cylindrical shell can be met when variations in temperature generation is expanded with heat and contract with cold, the sealing effectiveness between the kiln cylindrical shell of rotation and fixed enclosure is made to reach perfect condition, during the cylindrical shell dilatation of kiln, control fluctuate hermetical ring by cylinder to move, the encapsulant ring of fluctuate hermetical ring and rotating seal ring both sides is compressed, structure is simple, easy for installation, production cost is low, sealing effectiveness is desirable, Long-Time Service is not fragile, failure rate is low, easy to maintenance.
The utility model to achieve these goals, adopt following technical scheme: a kind of high temperature huge revolving kiln controls sealing device automatically, be by: kiln, fluctuate hermetical ring, dividing plate, encapsulant ring, rotating seal ring, expansion joint, cylinder, fixed enclosure are formed; Kiln periphery arranges rotating seal ring, the both sides of rotating seal ring arrange encapsulant ring, the periphery of rotating seal ring and encapsulant ring arranges fluctuate hermetical ring, between the fixed enclosure of kiln side and fluctuate hermetical ring, expansion joint is set, at least two cylinders are set between the periphery fixed enclosure of expansion joint and fluctuate hermetical ring.
Described rotating seal ring is at least two; Arrange at least one piece of dividing plate in described fluctuate hermetical ring, make to form at least two seal cavities in fluctuate hermetical ring, described each rotating seal ring and the encapsulant ring of both sides are arranged in a seal cavity; Described rotating seal ring, between encapsulant ring and fluctuate hermetical ring, form labyrinth type space.
Cross section when arranging one piece of dividing plate in fluctuate hermetical ring is E shape, described dividing plate and fluctuate hermetical ring one-body molded.
The beneficial effects of the utility model are: the utility model adopts end face to compress mazy encapsulating method, major diameter kiln cylindrical shell can be met when variations in temperature generation is expanded with heat and contract with cold, make the sealing effectiveness between the kiln cylindrical shell of rotation and fixed enclosure reach perfect condition.During the cylindrical shell dilatation of kiln, control fluctuate hermetical ring by cylinder and move, the encapsulant ring of fluctuate hermetical ring and rotating seal ring both sides is compressed.When kiln intensification cylindrical shell extends, expansion joint elongated dynamic air cylinder extends automatically, and cylinder extends promotion fluctuate hermetical ring and moves, and the encapsulant ring of fluctuate hermetical ring and rotating seal ring side is compressed; When kiln cooling cylindrical shell shrinks, expansion joint contraction bands dynamic air cylinder shrinks automatically, and cylinder shrinks and pulls fluctuate hermetical ring to move, and the encapsulant ring of fluctuate hermetical ring and rotating seal ring opposite side is compressed.When the temperature that ensure that the utility model rises and declines, the sealing effectiveness between kiln and fixed enclosure.
Be not limited between fluctuate hermetical ring and fixed enclosure adopt cylinder, other device also can be adopted to adjust the movement of fluctuate hermetical ring, and the encapsulant ring controlling fluctuate hermetical ring and rotating seal ring both sides compresses.Encapsulant ring adopts nonabradable encapsulant, extends service life of the present utility model.
The utility model adopts the form of end face seal and labyrinth sealing combination, the sealing property requirement in elevated pressures situation can be ensured, achieve the dynamic seal (packing) of major diameter high temperature rotating kiln, because cylinder holds out against effect, pre-tightening seal is voluntarily realized in equipment runs, significant sealing affection, without the need to manual operation, can according to seal request, can adopt multi-stage sealed, ensure sealing effectiveness, that is: two or more rotating seal rings are set in kiln periphery, one piece or one piece are set in fluctuate hermetical ring with upper spacer, make to form two or more seal cavities in fluctuate hermetical ring, the encapsulant ring of a rotating seal ring and both sides is arranged in a seal cavity.The utility model structure is simple, and easy for installation, production cost is low, and sealing effectiveness is desirable, and Long-Time Service is not fragile, and failure rate is low is easy to maintenance, reduces production cost, enhances productivity, be applicable to applying.
