1, the first ring mechanism 2 is set on vacuum mixer side wall 5；Along the radial direction of the first ring mechanism 2, the first ring mechanism 2
The first groove 21 of inside setting, filler 6 are set in the first groove 21；It is provided on second ring mechanism 3 and the first groove 21
The protrusion 31 to match, protrusion 31 are set in the first groove 21 filled with filler 6；Third ring mechanism 4 is set to second
On ring mechanism 3.The application is by the way that the first ring mechanism 2 to be fixed on vacuum mixer side wall 5, and in the first ring mechanism
The first groove of radially setting 21 on 2, the interior setting filler 6 of the first groove 21, it is preferable that filler 6 is along the first groove 21
It is arranged radially；Compared with filler 6 is wound in rotary shaft 21 along axial direction, the problem of axial filler abrasion is not present in the application,
And it is squeezed by the filler 6 in 31 pair of first groove 21 of protrusion on the second ring mechanism 3, effectively reduces filler
6 rate of depreciation；And due to not using vacuum tank, but the gland seal device of the application is set on vacuum mixer side wall 5,
Efficiently avoid negative issue caused by vacuum tank.
First ring mechanism 2 is stationary ring, and the second ring mechanism 3 is floating ring, and third ring mechanism 4 is that driving compresses
Ring.It is bolted to connection between third ring mechanism 4 and the second ring mechanism 3.Preferably, the first ring mechanism 2, second
Ring mechanism 3, third ring mechanism 4 are set as split type structure, and split type structure includes two symmetrical semi-circular structures, and two
Semicircle mechanism is bolted to connection, and positioning pin or/and retaining mechanism are further arranged in semi-circular structure.This axle envelope dress
Setting stationary ring, floating ring and driving compression ring is split type structure, i.e. dissection type constructs, and compares integrated molding formula structure, seperated
The dismounting of formula mechanism is more convenient, and the greatly easy checking maintenance operation of gland seal device improves checking maintenance efficiency.
The gland seal device of the application further include: first be set between the first ring mechanism 2 and vacuum mixer side wall 5
Interrupter 7.First interrupter 7 plays the role of the first ring mechanism 2 is isolated with vacuum mixer side wall 5, effective to drop
The defect that sealing is deteriorated caused by the low deformation expanded with heat and contract with cold due to vacuum mixer 5 and impurity is extruded or enters.
The gland seal device of the application further include: the second interrupter being set between rotary shaft 1 and the second ring mechanism 3
8.In 5 operation process of vacuum mixer, circular runout inevitably occurs for rotary shaft 1, and the second interrupter 8 can buffer
Bearing is to the radial brinelling of the second ring mechanism 3, while the impurity outside can playing sealing function, stopping enters axle envelope
Inside device, the equal leakage of filler 6 can also be prevented.
In the gland seal device of the application, the second interrupter 8 is set in the second groove 32 of the second ring mechanism 3.
Labyrinth seal 22 is set on the inside of first ring mechanism 2 of 1 side of rotary shaft.Labyrinth seal 22 is used
In the outflow or inflow that prevent material.
The gland seal device of the application, the first interrupter 7 or/and the second interrupter 8 are O-ring.O-ring is rubber material
Material, it is flexible, it being capable of buffering collision of closed abrasion.This gland seal device by labyrinth seal 22, the first interrupter 7 or/and second every
It disembarks 8 auxiliary seal of structure, prevents impurity from entering inside gland seal device, prevented the problem of exogenous impurity is stained filler, greatly prolonged
The service life of filler, further lift-off seal effect are grown.
The gland seal device of the application is provided with stop pin 9 in the first groove 21.Stop pin 9 is in the second ring mechanism 3
It is pressed under effect in filler 6, therefore stop pin 9 plays the role of preventing 6 sliding transfer of filler, is further ensured that filler
6 it is tightly packed in the first groove 21, prevented filler occur in the process of running relative shift influence sealing effect the problem of.
The gland seal device of the application further include: the elasticity being set between the second ring mechanism 3 and third ring mechanism 4 passes
Motivation structure 10.
The gland seal device of the application, elastic driving mechanism 10 include: trundle 11 and spring 12, and trundle 11 is set to
Between two ring mechanisms 3 and third ring mechanism 4, and spring 12 is set on trundle 11.12 sets of spring on trundle 11,
It is sandwiched between the second ring mechanism 3 and third ring mechanism 4, spring 12 is in the oppression state after installing, and can either guarantee
Filler 6 and protrusion 31 fit closely guarantee sealing effect in real time, and can guarantee that filler 6 will not be damaged by excessive compression, if
It counts more scientific.
The gland seal device of the application, filler 6 are soft packing.The application is by embedding soft packing in the first ring mechanism 2, and
The convex portion 31 of two ring mechanisms 3 is fitted closely with soft packing, while third ring mechanism 4 being driven to pass through elastic driving mechanism
10 are connected with the second ring mechanism 3.It drives on the elastic driving mechanism 10 between third ring mechanism 4 and the second ring mechanism 3
Equipped with spring 12, the elastic potential energy of spring 12 is transferred to the embedded soft packing of the first ring mechanism 2 by the second ring mechanism 3,
So that forming the sealing surface fitted closely between the first ring mechanism 2 and the second ring mechanism 3, while guaranteeing that soft packing is pasted completely
Close 2 inner groovy of the first ring mechanism.So set, in gland seal device operational process sealing surface will not because of filler abrasion or
The circular runout of rotary shaft 1 and the phenomenon that leak air, ensure that the long term seal effect in use process；And this gland seal device
Only relying on the included lubricating fluid of soft packing can reach good long term seal effect, referred to as dry type self-lubricating seal, be not necessarily to
Additional addition supplemental lubrication liquid；And the soft packing of this gland seal device is not in contact due to being to radially fill with rotary shaft 1, and by
The big uniform force of power area, not will cause soft packing rapid wear, avoid 1 circular runout of rotary shaft to the extruding of filler 6 and
Abrasion, extends the service life of soft packing.
Emphasis describes the difference between each embodiment, difference between each embodiment in the application foregoing embodiments
As long as optimization feature non-contradiction, can combine to form more preferably embodiment, it is contemplated that style of writing is succinct, then no longer superfluous at this
It states.
The above description is only an example of the present application, is not intended to limit this application.For those skilled in the art
For, various changes and changes are possible in this application.All any modifications made within the spirit and principles of the present application are equal
Replacement, improvement etc., should be included within the scope of the claims of this application.
