Scab seriously and rugged environment proposes higher requirement to sealing property；It is applied to revolution at present
Several sealing devices of kiln, sealing can be divided into static seal and movable sealing two kinds, and its movable sealing is divided into again and connecing
Touch type movable sealing and non-contact seal.The most domestic sealing device on rotary kiln mainly has fan
Palace formula sealing device and contact type sealing device, it addition, also graphite block formula sealing device；Sheet type
Sealing device；Wearing piece carries material sealing device and hermetically sealing device etc.；Labyrinth-type excluder is tied
Structure is simple, is not in contact with face, there is not wear problem, is not affected by cylinder vibration simultaneously.In order to
Dynamic and static sealing ring is avoided to come in contact at the volley, it is contemplated that the expanding with heat and contract with cold of cylinder, vibration, curved
The factors such as song, circular runout, no matter labyrinth sealing all can not be too at radial and axial preset clearance
Little, therefore labyrinth sealing disadvantage is that sealing effectiveness is undesirable, is only applicable to the occasion that pressure is little
Or be used in combination with other sealing；Contact type sealing device can keep it kind close in life-time service
Feng Xing.But higher to friction part material requirements, serious wear, maintenance is frequently.Axial contact seals
Structure is complicated, inconvenient maintenance；Radial contact seal simple in construction, easy to maintenance, but quick abrasion,
Affect sealing effectiveness.
This utility model is contemplated to solve above asking, topic and the improvement that carries out.
