Description
Technical field
The present invention relates to crude tailings Paste mixers, more particularly to a kind of shaft end seal knot of crude tailings Paste mixer
Structure.
Background technique
At present in fields such as ore dressing, chemical industry, coal washing, wastewater treatment, tailings glass, the application of crude tailings Paste mixer is very
Extensively.In these areas, blender key equipment is related to the structural strength of filling material, pack effectiveness etc..But use process
In often there is shaft end spillage leak, cause the component wears such as axle end bearing damage, cause parts thereof to fail, cause equipment
Failure is caused to shut down and be stopped production.Therefore, crude tailings paste body filling agitator shaft end seal problem is badly in need of as those skilled in the art
It solves the problems, such as.
Due to horizontal mixer work when, often take two groups of sealings, before one group be rotary shaft to the close of working media
Envelope, rear set is the sealing of bearing, enters bearing bearing working face to prevent the working medias such as mortar.Between two groups of sealings also
It must be isolated.
When agitating shaft rotary work, working media (mortar) is easy to rotate into rotating contact pair with axis, because high
The circular runout that the axis of load is inevitably generated when stirring and rotating, this circular runout make the dynamic clearance of sealing surface
It increases, and then causes leakage to aggravate, and hold remoter place off axis, circular runout is bigger, thus large-size horizontal stirs arbor
End sealing faces very big challenge due to circular runout problem.
Solution commonplace at present is using mechanical labyrinth sealing+packing+floating sealing ring sealing means, this side
It is to convert the radial cylindrical surface sealing of the rotation of axis between axial end face by floating sealing ring to seal that case, which is theoretically said, to advise
It keeps away and seals risk brought by shaft run-out, do so, add sealing effect obviously good many on the surfaces of revolution than simple,
But it due to causing the basic reason i.e. circular runout of seal failure not improved, is arranged so in the road surfaces of revolution Shang Qian disk
Often service life is short for root sealing, and after its failure, superfine tailings slurry is just easy to destroy under rotary motion promotion floating
The end face seal of seal ring, in addition floating sealing ring is since the design feature of itself is to processing, installation requirement height, and repair demolition is very not
Just.Thus there is also certain shortcomings for this technology path.
