Description
Technical field
The utility model is related to mechanical structure field, more particularly to a kind of dragveyer inner guide pulley is with can the sealing changed of full water
Structure.
Background technology
Dragveyer is widely used in slagging-off field as a kind of conveying equipment.Now the inner guide pulley of current in the market has a variety of shapes
Formula, has bearing built-in, bearing external by structure type point, has hydrolock, oil seal type, packing seal etc. by seal form point
Deng.The sealing that existing external inner guide pulley is used mostly is water seal+rubber oil sea, and this seal form is in high concentration buck
Poor effect.Especially when water route is cut off the water supply, water seal does not have due effect.In gasification furnace submerged slag conveyor in use, due to
Guide wheel is long-term to be operated in the sewage of lime-ash, and working environment is severe, and clinker water enters in guide wheel, and the very high molecule of hardness is long
Time contacts with rubber oil sea, oil sealing can be ground away, and grey solid impurity particle enters stuck bearing in raceway, and abrasion is accelerated, caused
Inner guide pulley damages the service life for shortening equipment.The sealing structure of existing inner guide pulley need to be changed once for 1-2 weeks, be changed every time
Be both needed to emptying water body to change again, generally requiring 7-10 hour could change and finish, waste time and energy, maintenance cost it is high.
Utility model content
To solve drawbacks described above present in prior art, the utility model aims to provide one kind can be in dragveyer not draining
In the case of change sealing, can be under operating conditions from solid sealed dragveyer inner guide pulley with can the sealing structure changed of full water.
In order to realize above-mentioned utility model purpose, the utility model uses following technical scheme：A kind of dragveyer inner guide pulley
With can the sealing structure changed of full water, including set gradually near water end to far water end seal cage, outside framework oil seal structure and big
Grease sealed structure（Seal cage, outside framework oil seal structure and big grease sealed structure are prior art, be will not be repeated here, under
Together）；The sealing structure is additionally provided with mechanical dynamic seal structure, the machinery on the seal cage front end water body side closer near water end
Movable sealing structure is disposed with the ripple that the bearing structure being fixed in rotating shaft, left end are fitted in bearing structure bottom by left-to-right
The resin dynamic sealing that shape wave turn, left end are brought into close contact with Wave shape spring spring coil right-hand member and outer is matched with bearing structure endoporus
Ring, left end and resin rotary packing ring right-hand member are brought into close contact and are provided with the high intensity of at least two layers ptfe plastic sealing ring and seal surely
Ring；Wherein described resin rotary packing ring right-hand member determines sealing ring left end flatness with high intensity and is at least 5 μm；Wave shape spring spring coil
Compressive state is in when often.
Above-mentioned dragveyer inner guide pulley is with can be in the sealing structure changed of full water, and the resin rotary packing ring right-hand member is further fixed on
One layer of nano aluminium oxide and molybdenum disulfide mixed coating.
Above-mentioned dragveyer inner guide pulley with can in the sealing structure changed of full water, the resin rotary packing ring with bearing structure
The region of endoporus matching is additionally provided with least two layers ptfe plastic sealing ring.
Compared with prior art, the utility model has advantages below：Most common seal failure is former in the prior art
Because high temperature dirt impulsive force is larger, and the hydraulic pressure in watertight construction is not enough, causes buck to squeeze watertight construction, hardness is very
High molecule is contacted with rubber oil sea for a long time, oil sealing can be ground away, and grey solid impurity particle enters stuck axle in bearing housing
Hold, abrasion is accelerated, cause failure, the movable sealing structure that the utility model is used is calculated by sectional area, the pressure of most of buck
Power will act on bearing structure left end, and bearing structure is moved to right by Wave shape spring spring coil extrusion resin rotary packing ring, move resin
Sealing ring is determined sealing ring with high intensity and is more brought into close contact, and has blocked the passage that buck flows via fit clearance to bearing housing, by
In the secure seal of ptfe plastic sealing ring, therefore buck also cannot be introduced into Nei Dao, the more big then dynamic sealing knot of buck surge
Seal tighter at structure, in the operating condition with significantly from sealing effect, and preferred nano aluminium oxide and molybdenum disulfide are mixed
Close coating and greatly reinforced wearability and the anti-attrition of resin rotary packing ring, greatly improve this service life to friction pair
（About 70000 working hours or so are promoted to from 20000 working hours）, the high tenacity combination waveform turn of resin it is slow
Punching, makes the shock resistance of movable sealing structure be greatly improved；Buck it is unique possibly through region be from resin
Rotary packing ring, even if now flowing into a little liquid flow to inner chamber, can not also be broken through other several layers of close with being flowed into bearing structure gap
Seal structure, will not be impacted to bearing housing, and ptfe plastic sealing ring of being set up in this region preferably is even more to block this road, greatly
Enhance sealing effectiveness greatly；The utility model is in seal structure damage, even if not emptying water body, only the fortune of disabling faulty guide wheel
Turn, investigation can be also upside down from bearing housing and is out of order a little, then repairs, need not be stopped in maintenance process, other guide wheel work are just
Often, maintenance time and maintenance cost are greatly reduced.
