Description
Technical field
The utility model is related to technical field of sealing technology, and in particular to a kind of metal honeycomb seal structure.
Background technology
At present, various types of sealings can be used between rotatable parts and stationary parts, such as：Brush seal, labyrinth are close
Envelope and honeycomb seal etc., wherein, brush seal is that protrusion bristle is set on the supporting member along stationary parts, and makes bristle with turning
Dynamic component is in contact to reach sealed effect, under normal circumstances, the effect of brush seal is fine, but due to brush seal
The shortcoming of itself, it can not bear very high pressure difference, therefore not be suitable for the sealing of the high occasion of big pressure difference.And labyrinth seal be according to
The gap between rotatable parts and labyrinth seal is passed sequentially through by fluid to occur section inhibition effect to reach sealing effectiveness, but due to fan
Palace is sealed has gap between rotatable parts, and therefore, the anti-leak characteristic of labyrinth seal is not fine, and due to labyrinth seal
Tooth scrapes rotatable parts, and the damage to rotatable parts is larger.Honeycomb seal is compared with labyrinth seal, although on resistance leaking performance
There is larger improvement, but still suffer from seal clearance and be more easily damaged the disadvantage for causing leakage to increase.And more existing use
The sealing of part, not only requirement can bear larger pressure difference, and require to reduce the infringement to rotatable parts, and existing sealing shape
Formula, which is unable to reach, both ensures sealing effectiveness, and larger pressure difference can be born again and reduces the requirement damaged to rotatable parts.
Utility model content
The purpose of this utility model is to provide a kind of metal honeycomb seal structure, to solve existing metal honeycomb seal structure
The problem of cost height, poor sealing effectiveness, not dust-proof and big energy resource consumption.
For up to above-mentioned purpose, the technical scheme that the utility model is used is：A kind of metal honeycomb seal structure is provided, wrapped
Include seal, sealing shroud and gear bush；Seal groove is provided with inside sealing shroud, the top of seal is provided with shoulder, and shoulder is set
Put in seal groove, seal is provided with honeycomb seals and brush seal, honeycomb seals include axially arranged first
Cellular band and with vertically disposed second cellular band of the first cellular band, honeycomb seals both sides are provided with magnetic pole, and magnetic pole is located at close
Seal in the interior sealing end face of body and the hole of embedding sealing body；Brush seal is located at the both sides of honeycomb seals, brush seal
Bristle tuft fixed by supporting member, supporting member is fixed in the annular groove of seal.
It is preferred that, gear bush is fixed and is set on equipment rotating shaft.
It is preferred that, provided with sealing tooth between the first cellular band and the second cellular band, the material of sealing tooth is polyether-ether-ketone.
It is preferred that, supporting member is fixed by screws in the annular groove of seal.
It is preferred that, the height of the first cellular band is 5.5mm, and the height of the second cellular band is 4.8mm.
It is preferred that, magnetic pole is located on the inside of brush seal.
In summary, the utility model has advantages below：
1st, by setting brush seal on the side of seal, brush seal and the organic knot of honeycomb seals are made
Altogether, in use, brush seal is directly contacted with gear bush surface, it is to avoid honeycomb seals are directly contacted to equipment
The damage that rotating shaft is caused, and because honeycomb seals are clipped between brush seal, overcoming brush seal, to bear pressure difference small
Deficiency.The seal configuration is easy to assembly, and cost is low, is conducive to improving mechanical efficiency, reduces maintenance cost, saves the energy
And environmental protection.
2nd, the utility model can reach pair of choked flow and flow-disturbing by setting twice cellular band on honeycomb seal
Weight effect, and then good sealing effect.
3rd, the sealing tooth between the first cellular band and the second cellular band can make up by the dust granule isolation in medium outside
Labyrinth seal causes the not dust-proof defect of honeycomb seal because producing sub- asynchronous vibration and steam.

Embodiment
Embodiment of the present utility model is described in detail below in conjunction with the accompanying drawings.
In one embodiment of the present utility model, as shown in Figure 1 there is provided a kind of metal honeycomb seal structure, including it is close
Seal body 1, sealing shroud 2 and gear bush 9；The inside of sealing shroud 2 is provided with seal groove 8, and the top of seal 1 is provided with shoulder 4, shoulder
4 are arranged in seal groove 8, and seal 1 is provided with honeycomb seals and brush seal, and honeycomb seals include axially arranged
First cellular band 12 and with vertically disposed second cellular band 11 of the first cellular band 12, honeycomb seals both sides be provided with magnetic pole 7,
Magnetic pole 7 is in the interior sealing end face of seal 1 and the hole of embedding sealing body 1；Brush seal is located at the two of honeycomb seals
Side, the bristle tuft 6 of brush seal is fixed by supporting member 3, and supporting member 3 is fixed in the annular groove of seal 1.
Optimal enforcement example of the present utility model, gear bush 9 is fixed and is set on equipment rotating shaft 10；First cellular band 12 with
