Abstract
A kind of floating seal belongs to that oil is husky, oil shale rotary dry distillation technical field, containing outer simplified, inner barrel, inner barrel supporting, conveyance conduit, pipeline outer wall movable sleeving, seal receptacle, static seal A, dynamic seal, sunk screw, static seal B, sealing gland, spring, spring base, bolt, nut etc..Inner barrel is connected with conveyance conduit one end, equipped with pipeline outer wall movable sleeving on conveyance conduit, coordinate with dynamic seal endoporus spherical cambered surface outside pipeline outer wall movable sleeving, seal receptacle is connected with outer cylinder body through conveyance conduit, static seal periphery and seal receptacle fit inside, static seal makes conveyance conduit can seal at diverse location with outer cylinder body confluce with dynamic seal combination.Dynamic seal of the present invention floats with inner barrel change in location, and device sealing property is reliable, installs, adjusts and easy to maintenance, it is ensured that oil is husky, oil shale retorting is smoothed out.
Description
Technical field
The present invention relates to oil sand, oil shale rotary dry distillation technical field, a kind of rotary dry distillation stove urceolus
The internal high-temperature inner barrel body that is equipped with, in inside and outside cylinder, part material granular material needs with conveyance conduit through outer cylinder body
Outer helical carries out spike dry distilling in being transported to inner/outer tube body, its conveyance conduit and the one of outer cylinder body confluce
Sealing device.
Background technology
At present, application rotary dry distillation stove is as oil-sand. dry distillation method of oil shale, it usually needs design multilamellar revolution
Cylinder, passes through conveyance conduit around urceolus with semicoke in hot-engine sludge after dry distilling or dry distilling cylinder in retort process
External wall helical feed enters fire door blending to raw material, is not required to external source and makes oil-sand. and oil shale raw material reaches dry
Evaporate temperature, and inside and outside cylinder is due to furnace temperature equal reason when manufacture material and dry distilling, the conveying of conveying
Pipeline and the import of outer cylinder body confluce and outlet, expanded by heating before rotary dry distillation stove uses and during use
Its position can occur sizable change, a kind of method to be that inner barrel designs band expansion joint, inner barrel digest
The change in location that two cylinders cause because of thermal expansion difference, but large-scale inner barrel expansion joint manufacture difficulty is big；Another
The method of kind is to make dry distilling work with the floating seal of cylinder change at conveyance conduit with the design of outer cylinder body confluce
It is smoothed out.
Summary of the invention
It is an object of the invention to as semicoke in hot-engine sludge after solution rotary dry distillation stove dry distilling or dry distilling cylinder
Entering fire door by conveyance conduit around outer cylinder body outer wall helical feed to raw material to admix, conveyance conduit is handed over outer cylinder body
Hui Chu position changes with before using during rotary dry distillation stove uses, and requires conveyance conduit and urceolus
Body remains excellent sealing in this confluce, makes a material powder-material not leakage problem in outer cylinder body.
The technical solution adopted in the present invention is:
A kind of floating seal contains: outside the supporting of outer cylinder body, inner barrel, inner barrel, conveyance conduit, pipeline
Wall movable sleeving, seal receptacle, static seal A, dynamic seal, sunk screw, static seal B, sealing gland,
Spring, spring base, bolt, nut.Outer cylinder body is connected by inner barrel supporting with inner barrel, conveyance conduit one
End is connected with outer cylinder body, and the conveyance conduit other end is connected with inner barrel, pipeline outer wall movable sleeving endoporus and conveying
Pipeline lateral surface coordinates, and has identical spherical arc with dynamic seal endoporus outside pipeline outer wall movable sleeving, close
Envelope seat is connected with outer cylinder body through conveyance conduit, loads two static seal A, outside static seal A in seal receptacle
Week and seal receptacle fit inside, equipped with two dynamic seals static seal A in, two dynamic seal endoporus and
Outside pipeline outer wall movable sleeving, upper spherical arc cooperation is connected by sunk screw, and on dynamic seal, loading two is quiet
Sealing member B, static seal B periphery and seal receptacle fit inside, static seal B loads two and seals pressure
Lid, sealing gland coordinates with seal receptacle and is connected by spring, spring base, bolt, nut.It is contained in pipeline outer wall
Dynamic seal on movable sleeving can move radially with pipeline outer wall movable sleeving, again can be with pipeline outer wall movable sleeving
Out course arc oscillating, and dynamic seal is under certain spring pressure effect, in static seal A and quiet
Move axially with inner barrel and conveyance conduit between sealing member B, make conveyance conduit with outer cylinder body confluce all the time
Keep sealing.
In seal receptacle, two static seal A are vertical with two dynamic seals, two dynamic seals and two static seals
Part B is vertical, and two static seal B are vertical with two sealing glands；Static seal A, dynamic seal, quiet close
Sealing B, sealing gland end contact successively coordinates.
The invention has the beneficial effects as follows:
(1) pipeline outer wall movable sleeving and conveyance conduit are slidably matched and spherical arc outside pipeline outer wall movable sleeving
Contact with dynamic seal endoporus spherical arc, it is ensured that dynamic seal can move radially and swing；Quiet
Sealing member A and static seal B periphery coordinate with seal receptacle inner slide, static seal A, dynamic
Sealing member, static seal B coordinate to be adjusted by sealing gland, spring, spring base, bolt, nut
Joint, it is ensured that dynamic seal translates relative to static seal A and static seal B and laminating is good,
In outer cylinder body, granule powder-material does not leaks with outer cylinder body confluce at conveyance conduit；
(2) in seal receptacle, two static seal A, two dynamic seals, two static seal B and two are close
Sealed cover is disposed vertically composition end face seal each other, convenient to install and maintain.
(3) present invention solves conveyance conduit and the sealing of inside and outside cylinder confluce, from without at inner barrel
On manufacture and design the axially and radially thermal expansion that the expansion joint inside and outside cylinder of digestion causes because of temperature difference.
