Abstract
The utility model discloses a sealing device of a coal dry distillation rotation device. The sealing device comprises a moving ring set arranged on a rotation body and a sealing sleeve ring arranged on a motionless body, the moving ring set and the sealing sleeve ring are connected in a sealing manner via a scale set, a steam chamber is formed between the rotation body and the motionless body via the moving ring set, the sealing sleeve ring and the scale set, and the sealing sleeve ring is provided with steam inlets communicated with the steam chamber. A scale sealing mode is employed to achieve flexible sealing and a certain bounce of the rotation body can be tolerated; meanwhile, the steam in the steam chamber plays a role of sealing so that gas leakage can be prevented.
Description
Technical field
The utility model relates to a kind of mechanical seal device, is specifically related to a kind of coal destructive distillation turning round equipment seal arrangement.
Background technique
Existing coal destructive distillation turning round equipment seal arrangement mainly contains sound dish seal arrangement, packing_seal device and scale sealing device.
Wherein sound dish seal arrangement is mainly utilize rotating ring and stationary ring to solid of rotation and do not seal between kinetoplast, this type of sealing configuration because of rotating ring and and stationary ring between easy to wearly often can cause gas leakage, and be difficult for maintenance.
The packing_seal device mainly by solid of rotation and and the mode that Sealing is not set between kinetoplast and holds out against spring reach the purpose that is tightly connected, the problem that this type of seal arrangement exists is, when solid of rotation and when not coaxial between kinetoplast, equipment can shake and beat, the packing displacement is easy-regulating not, causes leakage.
Scale sealing device is by in solid of rotation and kinetoplast joint not, the scale diaphragm seal being installed, because of the mounting type between the elasticity of scale diaphragm seal self and itself and main equipment, this type of sealing configuration has relative advantage aspect the characteristic of " the tolerance solid of rotation is beated and the equipment distortion of expanding with heat and contract with cold ", but because its Sealing that adopts is not monolithic construction, so the easy leakage problem of ubiquity coal gas.
Summary of the invention
The coal destructive distillation turning round equipment seal arrangement that the purpose of this utility model is to provide a kind of good airproof performance, circular runout and the axial deformation of solid of rotation had higher tolerance.
For this reason, the coal destructive distillation turning round equipment seal arrangement that the utility model provides is the solid of rotation of coal destructive distillation turning round equipment and the seal arrangement between kinetoplast not, it comprises the rotating ring group that is installed on solid of rotation and is installed on sealing ring on kinetoplast not, be connected by the scale group between described rotating ring group and sealing ring, and rotating ring group, sealing ring and scale group are at solid of rotation and be not enclosed to form vapor chamber between kinetoplast, offer on described sealing ring with vapor chamber in the steam inlet that communicates.
The described rotating ring group that is installed on solid of rotation comprises the first rotating ring that is installed on solid of rotation and the second rotating ring that is installed on the first rotating ring; Be connected by the first scale group between described the first rotating ring and sealing ring, and the first rotating ring, sealing ring and the first scale group be at solid of rotation be not enclosed to form the first vapor chamber between kinetoplast, offer on described sealing ring with the first vapor chamber in the gas inlet that communicates; Be connected by the second scale group between described the second rotating ring and sealing ring, and the second rotating ring, sealing ring and the second scale group are at solid of rotation and be not enclosed to form the second vapor chamber between kinetoplast, offer on described sealing ring with the second steam cavity in the gas inlet that communicates.
Described the first rotating ring is provided with cold passageway.
Described the second rotating ring is provided with cold passageway.
Described the first scale group is provided with spring outward and opens into wire rope.
Described the second scale group is provided with the tight part of sealing pressing outward.
Seal arrangement of the present utility model has following features:
(1) utilizing the method for scale sealing to carry out flexible sealing tolerable solid of rotation has necessarily and beats;
(2) adopt the way that steam passes into to guarantee that coal gas does not leak outside.
