Production needs through being difficult to meet emerging industry.It is that all conglomeraties realize heavy industrialization to develop a kind of completely new production equipment
Prerequisite.
Vacuum equipment is made to realize enlargement, main technical barrier is sealing problem.The contact of two objects generally divides
For point contact, line contact, face contact, wherein be most difficult to realize with face contact especially, because can not possibly accomplish the substantially flat of two faces,
Also it is impossible to accomplish to be bonded completely.Similarly, the sealing of vacuum equipment is exactly the core difficult point of whole equipment.The difficult point is not only
It is the sealing in two faces, the sealing between also dynamic and static face.Dynamic face follows kiln body to rotate together, and quiet face is other equipment
With the junction of kiln body.
Since kiln body intracavitary is vacuum, the pressure between sound face is very big, and frictional force between the two also can be very big, moves
The life problems of quiet plane materiel material are exactly a big difficulty.The material of short life can greatly influence to produce, if value is higher
Product, each replacement sound contact sealing material are exactly a greatly loss, it is impossible to which continuous production affects production.
Substance in nature follows the rule expanded with heat and contract with cold mostly, kiln body be heated after be dilatable, but due to true
Empty relationship, both ends have very big power compressing kiln body.The safety for ensureing kiln body is a difficult point of design again.
In view of the above shortcomings, the designer, is actively subject to research and innovation, forged to found a kind of turned round for vacuum
The end face seal structure of firing, to solve above-mentioned technological difficulties.

Cylinder 300 is identical with 402, two structures of the stationary ring 401 on the end of dynamic cylinder 200 and rotating ring and is oppositely arranged and is held on stationary ring
Wear ring 403 between 401 and rotating ring 402.
The utility model is by making one of 403 follower sleeve 200 of wear ring rotate together, another wear ring 403 is quiet
Only, two 403 phase mutual friction of wear ring, after vacuum kiln body 100 is heated, due to expanding with heat and contract with cold, vacuum kiln body 100 is drawn to both ends
It stretches, static wear ring 403 is by the thrust of wear ring 403 rotated；When in vacuum kiln body 100 being negative pressure, in atmospheric pressure
Under effect, the wear ring 403 of rotation by static wear ring 403 thrust, in this way, can be mutual between two wear rings 403
It squeezes, reaches end face seal effect, ensure that vacuum rotary calciner can be continuously run.
To make stationary ring 401 and rotating ring 402 that can steadily clamp two wear rings 403, the wear ring 403 of the utility model
Both ends are respectively the first ring portion and the second ring portion, and the first ring portion forms ladder axle sleeve structure with the second ring portion；Stationary ring 401 and dynamic
The both ends of ring 402 are respectively the first support ring and the second support ring, and the first support ring forms ladder axle sleeve with the second support ring
Structure, the step between the first support ring and the second support ring support one be relatively large in diameter in the first ring portion and the second ring portion；
The diameter of one being relatively large in diameter in first ring portion and the second ring portion, which is less than in the first support ring and the second support ring, to be relatively large in diameter
The diameter of one, and the step between the first ring portion and the second ring portion is equipped with and compresses the flange 409 of wear ring 403, flange
409 are locked at by bolt 410 on one be relatively large in diameter in the first support ring and the second support ring.In the present embodiment, second
The diameter of ring portion is more than the diameter of the first ring portion, and the diameter of the first support ring is more than the diameter of the second support ring, and the first support
The diameter of ring is more than the diameter of the second ring portion, in this way, wear ring 403 is sleeved in the second support ring, and abuts the second ring portion
In the first support ring, flange 409 compresses the second ring portion, and bolt 410 passes through 409 and first support ring of flange, thus will be wear-resisting
Ring 403 is locked at stationary ring 401, on rotating ring 402.
For protection stationary ring 401, rotating ring 402 and two wear rings 403 between the two, the utility model is on stationary ring 401
It is connected with the protective plate 411 for covering 401, two wear rings 403 of stationary ring and rotating ring 402.
The utility model is related to vacuum rotary calciner, be set on chassis 600, including cylindricality horizontal vacuum kiln body
100, the both ends of vacuum kiln body 100 are rotatably connected to the dynamic cylinder 200 communicated therewith, and dynamic cylinder 200 is socketed with quiet cylinder 300, quiet cylinder 300
Above-mentioned end face seal structure 400 is equipped with the socket place of dynamic cylinder 200, the support platform 602 of chassis 600, which is equipped with, supports quiet cylinder
300 rolling assembly.In two quiet cylinders 300, one of them quiet cylinder 300 be used as feeding cylinder, another as discharge barrel, and
As on the quiet cylinder 300 of feeding cylinder set feed inlet, as on the quiet cylinder 300 of discharge barrel set discharge port 301.In addition, vacuum
Kiln body 100 is electrical heating type, and the vacuum rotary calciner of the utility model can be applied to molecular sieve roasting, inertia/reducing atmosphere
The fields such as roasting, noxious material harmless treatment.
Secondly, using the rolling assembly for supporting quiet cylinder 300, when static wear ring 403 is by the wear ring 403 rotated
During thrust, which can pass to rolling assembly, so as to which quiet cylinder 300 be made to move outward so that between two wear rings 403
Energy phase mutual friction when mutually squeezing, when in vacuum kiln body 100 being negative pressure, atmospheric pressure applies active force, the effect to quiet cylinder 300
Power passes to rolling assembly, so as to move inward quiet cylinder 300, makes mutually squeeze between two wear rings 403.That is, rolling
Wheel assembly can support quiet cylinder 300 to move along its axis.Under the action of expanding with heat and contract with cold, 100 expanded by heating of vacuum kiln body can phase
It should extend, setting roll wheel assembly can prevent the power of elongation generation and damage equipment.In the utility model, rolling assembly include with it is quiet
The stent 501 of 300 connection of cylinder, stent 501 are connected with bearing 502, and 502 bottom of bearing is connected with multiple pulleys 503, in addition, branch
Support platform 602 is equipped with the sliding slot that coordinates with each pulley 503, and when rolling assembly is by thrust, pulley 503 is along support platform
602 slide.Since 602 upper part of support platform has support platform 602 downward active force, the too big frangibility branch of active force
Platform 602 is supportted, therefore, the utility model is connected with channel steel 601 between support platform 602 and chassis 600, and channel steel 601 plays
The effect of reinforcement.
Extruding force in order to prevent between rotating ring 402 and stationary ring 401 is excessive and is damaged, and the utility model is in quiet cylinder
300 are circumferentially uniformly arranged multiple gussets 404 with the end of dynamic cylinder 200, each gusset 404 support respectively corresponding stationary ring 401 with
Rotating ring 402.
In order to rotate cylinder 200, the utility model sets motor 204 on chassis 600, and rolling is arranged on dynamic cylinder 200
Circle 203, motor 204 is sequentially connected with rolling ring 203, you can the dynamic cylinder 200 of driving rotates.
In order to which further smoothly branch racking cylinder 200 rotates, the utility model is equipped on chassis 600 and supports each dynamic cylinder
200 support roller 201 is arranged with the wheel belt 202 contacted with support roller 201 on each dynamic cylinder 200.
To sum up, the end face seal structure of the utility model by the way that one of wear ring follower sleeve is made to rotate together, it is another
A wear ring is static, and two wear rings mutually squeeze, rub, and reach end face seal effect, ensure that vacuum rotary calcining
