Description
Technical field
The utility model belongs to Fan Equipment field, and in particular to a kind of fan sealing device.
Background technology
Wind turbine is the capital equipment of timber industry Geldart-D particle, and sealing device is one of key device of wind turbine.In life
In producing line in Geldart-D particle flow process, fan sealing device can be used for effectivelying prevent pernicious gas and dust to leak.It is existing
Fan sealing device generally comprised the structures such as sealing ring, cause sealing device stability poor；And it is complicated, it is not easy to
Debugging and maintenance.
Invention content
The utility model aim is to provide a kind of fan sealing device for overcome the deficiencies in the prior art.
In order to achieve the above objectives, the technical solution adopted in the utility model is：A kind of fan sealing device, it includes：
Seal assembly, the seal assembly include graphite bushing, housing and discharge hole, and the graphite bushing includes at center
The set ontology of accommodating hole is offered, the first connection bulge loop of the set ontology circumferential surface end is integrally formed at and is opened in described
Connecting hole on first connection bulge loop, the housing is sheathed on the circumferential surface of the set ontology and its end face is connect with described first
Bulge loop is in contact, and the discharge hole runs through the set ontology and the housing and extends to and is connected with the accommodating hole；
One end of anti-fistulae, the anti-fistulae is connected with the discharge hole.
Optimally, the inner surface of the set ontology is formed with spaced multiple-sealed protrusion, and sealing described in per pass is convex
The axial line of the axial line risen and the set ontology overlaps.
Further, the end of the housing circumferential surface is formed with the second connection bulge loop, the second connection bulge loop and described
First connection bulge loop is located at the both sides of the discharge hole.
Since above-mentioned technical proposal is used, the utility model has following advantages compared with prior art：The utility model
Fan sealing device substitutes conventional plastic seal coil structures by using the graphite bushing of specific structure, is conducive to improve close
The stability of seal apparatus, it is safe and convenient for safeguard.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model fan sealing device；
Fig. 2 is the partial enlarged view of Fig. 1.
Specific implementation mode
The utility model preferred embodiment is described in detail below in conjunction with attached drawing：
Fan sealing device as shown in Figure 1 includes mainly seal assembly 1 and anti-fistulae 2 etc..
Wherein, seal assembly 1 includes graphite bushing 11, housing 12 and discharge hole 13, and graphite bushing 11 includes being opened at center
Equipped with accommodating hole 113（Graphite bushing 11 is used to be sleeved on the rotation axis of wind turbine so that accommodating hole 113 and rotation axis outer surface phase
Adaptation）Set ontology 111, be integrally disposed upon set ontology 111 circumferential surface end（Cover the end of 111 circumferential surface of ontology）First connection
Bulge loop 112 and the connecting hole 114 being opened on the first connection bulge loop 112, housing 12 be set on the circumferential surface of ontology 111 and
Its end face connect bulge loop 112 with first and is in contact, in this way by connecting hole 114 mounting screw graphite bushing 11 may be implemented
With the connection of housing 12；In the present embodiment, housing 12, graphite bushing 11 can be arranged respectively to two symmetrical pairing knots
Structure can utilize the docking of housing 12 to realize the quick disassembly and installation of seal assembly 1 in this way.And discharge hole 13 then runs through set originally
Body 111 and housing 12, and extend to and be connected with accommodating hole 113.One end of anti-fistulae 2 is connected with discharge hole 13, another
End, which is then extended to, to be connected with wind turbine and forms negative pressure will cover 111 remaining substance of ontology（Such as pernicious gas and dust）It inhales
It walks.Unique seal assembly 1 and anti-fistulae 2 carry out cooperation can preserve value sealing device sealing stability it is good, safe, just
In maintenance, consequently facilitating debugging and meeting environmental protection demand.
In the present embodiment, the inner surface of set ontology 111 is formed with spaced multiple-sealed raised 115, and per pass is close
The axial line of envelope protrusion 115 and the axial line of set ontology 111 overlap, to further increase the stability of sealing, such as Fig. 2 institutes
Show.The end of 12 circumferential surface of housing is formed with the second connection bulge loop 121, is fixed for housing 12 and the installation of other blower fan structures,
And the second connection bulge loop 121 and first connects the both sides that bulge loop 112 is located at discharge hole 13, they are being installed respectively in this way
When not will produce interference and ensure installation convenience.
Above-described embodiment is only the technical concepts and features for illustrating the utility model, and its object is to allow be familiar with technique
Personage can understand the content of the utility model and implement according to this, the scope of protection of the utility model can not be limited with this,
It is all according to equivalent change or modification made by the spirit of the present invention essence, should all cover the scope of protection of the utility model it
It is interior.
