Device.
Background technology
In daily industrial and agricultural production, including the use of the graininess material storage storage such as raw coal, mineral powder is extremely popularized, its
Effect can not be underestimated.But the generation of feed blocking phenomenon is often had during warehouse discharging is stored, have a strong impact on equipment
Normal work.The particularly run coal bin and coke-oven plant's coal tower of large-size thermal power plant configuration unit pulverized-coal system, power plant
Once lower coal occurs to block, generating set will be forced promptly to drop output removal of load, or even boiler combustion shakiness occur and cause greatly
Amount throws oil, and more serious meeting causes boiler extinguishment, unit unplanned outage.Coke-oven plant blocks once lower coal occurs, whole coal blending
Ratio occurs as soon as imbalance, causes defeated coal to interrupt when serious.Run coal bin chute blockage problem turns into a professional problem.It is such to solve
Problem, people control to block in run coal bin adds rotary cleaner.
Outer rotary cleaner can largely solve blockage problem, and outer rotary cleaner is using process
In, higher is required to its sealing property, conventional sealing structure is divided into dynamic sealing and static seal, and dynamic sealing is divided into reciprocation sealing again
And rotatory sealing.But conventional sealing is used in outer rotary cleaner and easily produces seal failure, so as to cause to leak, so
Work to whole outer rotary cleaner produces large effect, can also influence the motion of other executing agencies.
The content of the invention

There is sylphon seal device, one end contact of the sylphon seal device is on the end face of the abutment sleeve, and in the ripple
The other end of tube sealing device is provided with arresting disc, and sealing fastener is provided with the groove of the arresting disc, and the sealing is tight
Firmware is located at the outside of the axis body, and is provided with bearing A, the bearing A in the sealing fastener and is arranged on the axle
The outside of body；Packing seal is installed in one end of the bearing A, and the side of the packing seal and sealing fastener it
Between form gap, the rotating ring on axis body is provided with the gap, and oil absorbent material is installed on the sidewalls in the gaps；
Stationary ring is installed in the side of the rotating ring, bearing B, the bearing B are installed in one end of the stationary ring and are arranged on the axle
On body, and spiral seals are installed in one end of the bearing B.
Further, formed with compensation gap between the sealing fastener and axis body, and bearing A one end contact is in institute
State on the inner face of sealing fastener.
Further, the bearing A is taper roll bearing, and the bearing B is ball bearing.
Further, the oil absorbent material is bonded on the internal face of the sealing fastener.
Compared with prior art, the beneficial effects of the utility model are：The utility model at work, using bellows
Sealer, sealing fastener, rotating ring, stationary ring and spiral seals form the compensation sealing structure of combination, and axis body is working
During produce deflection deformation, by being provided with bearing A and bearing B in sealing fastener, can to axis body produce radially about
Shu Zuoyong, axis body is set to keep concentric structure with sealing fastener, so as to eliminate influence of the beat of axis body to sealing effectiveness,
The sealing structure that the utility model uses, using the teaching of the invention it is possible to provide good sealing effectiveness, prevent seal failure.
