Technical problem to be solved in the utility model is achieved by the following technical programs:
This axle end sealing device includes rotary shaft and fixing change hub on the rotary shaft, on described change hub at least one
Place's annular groove；Coordinate with change hub determines ring hub, described determines on ring hub at least annular protrusion at, determines the convex annular of ring hub
Rise and match mutually with the annular groove of described change hub.Labyrinth passage together with being formed between groove with projection.Described change hub
On the height of annular groove and width be respectively greater than height and the width of the described annular protrusion determined on ring hub, in labyrinth channel
Leave narrow and small gap.
Further, described change hub and the labyrinth passage determining the formation of ring hub are not limited to the profile of tooth at right angle, it is also possible to
It is the trapezoidal of obtuse angle, it is also possible to be waveform, and the passage of other complications.
Further, the described change hub groove mutually coincideing and the quantity determining ring hub protruding are the most, and sealing effectiveness is the best.
Further, the gap of described labyrinth channel invades the outside logistics in port side from foreign object and goes out port side and gradually become
Little.
Further, described ring hub is determined by screw or be bolted on the fixture of datatron shell.
Further, described change hub can be integrated casting with rotary shaft, it is also possible to is fixed together by welding.
Further, the end of described rotary shaft is provided with a bearing.
Further, described bearing is roller bearing.
Further, described determine to be provided with between ring hub and rotary shaft the first outside framework oil seal.
Further, it is provided with the second outside framework oil seal between last portion and the fixture of described rotary shaft axle head.
This utility model additionally provides a kind of innoxious degradation treatment machine, including degraded groove, is arranged on stirring in degraded groove
Mixing structure, the temperature control system being arranged on degraded groove and control system, its stirring structure employs described axle end sealing device, institute
State degraded groove and be additionally provided with dog-house, discharging opening and Waste gas outlet.
This utility model has the advantages that
By mazy shaft end seal passage, the path of oozing out of exudate becomes full of twists and turns, during oozing out, oozes
Go out the resistance suffered by thing to be greatly increased, such that it is able to effectively stop exudate to ooze out from axle head；When further equipment runs
Labyrinth passage internal pore can be filled up by the Organic substance degraded, and makes how the liquid in machine is instant also cannot ooze from axle head again
Go out；And the gap of labyrinth channel is avoided that change hub and determines to produce between ring hub metal friction, reduce the abrasion between device, increase
Add the service life of machine；The roller bearing of axle head can make axle end sealing device preferably bear the effect of main shaft tangential force.
Employing the innoxious degradation treatment machine of described axle end sealing device, its sealing effectiveness is more preferable, and parts
Between abrasion less, maintenance cost is lower, and service life is longer.
Accompanying drawing explanation
Fig. 1 is this axle end sealing device schematic diagram；
Fig. 2 is the enlarged diagram in Fig. 1 at A.
Detailed description of the invention
With embodiment, this utility model is described in detail below in conjunction with the accompanying drawings.
As shown in Figure 1, 2, a kind of axle end sealing device, including rotary shaft 1, change hub 2, determine ring hub the 3, first outside framework oil seal
4, the second outside framework oil seal 5, bearing 6, fixture 8.Change hub 2 is fixed in rotary shaft 1, and rotates with rotary shaft 1；Determine ring
Hub 3 is linked together with fixture 8 by screw, and the shell of fixture 8 and datatron connects；Described change hub 2 is towards determining ring
The side of hub 3 is provided with at least one annular groove, and described to determine ring hub 3 recessed with described annular towards being provided with on change hub 2 side
At least one annular protrusion that groove is corresponding, described annular groove matches with annular protrusion and forms the labyrinth of complications between the two
Passage 7.On change hub 2, height and the width of annular groove are respectively greater than height and the width determining annular protrusion on ring hub 3, thus
Narrow and small gap is left in making labyrinth channel 7.The gap of labyrinth channel 7 invades the outside logistics in port 71 side from foreign object and goes out port
72 sides taper into.First oil tight skeleton 4 is arranged to be determined between ring hub 3 and rotary shaft 1, and the second outside framework oil seal 5 is arranged at rotation
The axle head end portion of rotating shaft 1, between rotary shaft 1 and housing mount 8.Bearing 6 is arranged at the axle head of rotary shaft 1, and determines ring
Hub 3 is adjacent, between fixture 8 and rotary shaft 1.
When machine operationally, mazy passage increase degradation product infiltration road, degradation product first breaks through change hub 2
And the gap determined between ring hub 3, enter labyrinth channel 7, be blocked in labyrinth channel 7 under stopping on the passage of complications
Come, and strengthen the invasion resistance of invader below.The gap of labyrinth channel 7 invades port 71 side outside thing outflow end from foreign object
Mouth 72 sides taper into, and after penetrant invades labyrinth channel 7, penetrant nearer it is to flow out port, and suffered resistance is more
Greatly.Lubricating oil can be added to reduce friction and to strengthen the resistance of infiltration in labyrinth channel 7.When labyrinth is led to by the Organic substance of degraded
After road 7 internal clearance is filled, the effect sealed can be strengthened further, it is to avoid the grease of high temperature is through innoxious degradation treatment
The axle head seepage of machine.
Close gap in labyrinth channel 7, moreover it is possible to avoid producing between two structural members metal friction, reduce the mill of machine
Damage, increase the service life of equipment.
As further improvement of the utility model, it is also possible to by the bearing 6 of this sealing device rotary shaft 1 end by originally
Ball bearing of usheing to seat becomes roller bearing, and after using roller bearing, equipment can preferably bear generation when rotary shaft 1 works
Main shaft tangential force.
A kind of innoxious degradation treatment machine, the stirring structure including degraded groove, being arranged in degraded groove, is arranged on degraded groove
On temperature control system and control system, described rabbling mechanism and temperature control system be connected with control system, and described degraded groove is arranged
Having dog-house, discharging opening and Waste gas outlet, connecting at described Waste gas outlet has odor removal；Top at described degraded groove
It is provided with spray system；Described stirring structure employs described axle end sealing device so that this datatron sealing effectiveness is more preferable,
Maintenance cost is lower.
Embodiment described above only have expressed embodiment of the present utility model, and it describes more concrete and detailed, but also
Therefore the restriction to this utility model the scope of the claims can not be interpreted as, as long as using equivalent or the form institute of equivalent transformation
The technical scheme obtained, all should fall within protection domain of the present utility model.
