The flat spring I 7 of arcuate structure, the middle part of flat spring I 7 are fixed on seal holder ring I 4, and the both ends of flat spring I 7 are pressed on pressing plate I
On 6；The side wall that the seal holder ring II 5 is connected by side compresses the outer face of packing 3, and the opposite side of seal holder ring II 5 is set
There is gland 8, be provided with rubber seal ring 9 in the toroidal cavity between the side wall and gland 8 of seal holder ring II 5, on rubber seal ring 9
Pressure is provided with pressing plate II 10, and arc flat spring II 11, flat spring are provided with the toroidal cavity between pressing plate II 10 and seal holder ring II 5
II 11 middle part is fixed on seal holder ring II 5, and the both ends of flat spring II 11 are pressed on pressing plate II 10.
In order that the present invention has more preferable implementation result, rubber is additionally provided between described rubber seal ring 9 and gland 8
Sealing gasket 12.The rubber seal ring 9 has multiple lips 13, on seal holder ring II 5 along the circumferential direction spaced set have it is more
Individual oil filling pipe 14, lip of the oil filling pipe 14 through pressing plate and the circular hole by being arranged on rubber seal ring 9 and rubber seal ring 9
Gap connection between 13.Rubber seal ring 9 contains 2-6 bars lip 13, and the length of lip 13 differs.The oil filling pipe 14 passes through
Nut 16 is locked on the outer peripheral face of seal holder ring II 5.
The middle part of flat spring I 7 and flat spring II 11 is separately fixed at seal holder ring I 4 and sealing by regulating bolt 15
On seat ring II 5.The side of seal holder ring II 5 is fixed by gland 8, is consolidated between seal holder ring II 5 and gland 8 by bolt
It is fixed.
Flat spring I 7 is fixed on center hole on the shaft shoulder of the end of regulating bolt 15, with packing ring and split pin by flat spring
I 7 are connected with regulating bolt 15；Regulating bolt 15 is arranged on the nut of the outer circumference surface of seal holder ring I 4 welding, and uses locking screw
Mother's locking；Flat spring II 11 is fixed on the end shaft shoulder of regulating bolt 15, is fixed with pad and split pin；Regulating bolt 15 is installed
On the nut welded on the periphery of seal holder ring II 5, and locked with locking nut.
View A-A and view B-B reflect packing sealing structure and rubber seal ring sealing structure from axial direction respectively：
Several uniform same spring compression mechanisms, pressing plate are provided with gap to there is certain adjustment between any two on circumferencial direction
Surplus；
In view B-B, pressing plate II 10 reserves larger gap to arrange oil filling pipe 14 between any two；The one end of oil filling pipe 14 is deep
Enter to see in the gap of lip 13 of rubber seal ring 9 view C-C and D-D to being refueled in lip 13 and the cylindrical rubbing surface of cylinder,
The other end connects the oil circuit of centralized lubricating system.
Described seal holder ring II 5 has the roof platform of " T " shape structure with the joint of packing 3, and the platform end top of roof platform is located at
Packing side, the other end are connected with the body of seal holder ring II 5.
Using packing_seal form, and in the outer cylinder of packing 3, the pressing device of flat spring I 7 that can adjust is set so that
Packing 3 can follow bounce with cylinder circular runout, and after the concentrated wear of packing 3, can adjust crush, continue it
Keep compressing the outer cylinder of rotating cylinder 1.Between packing 3 and flat spring I 7, the pressing plate I 6 consistent with the cylindrical radian of packing is set,
To by the thrust of flat spring I 7 be evenly distributed on packing 3 it is cylindrical on.Flat spring I 7 is arc, and centre passes through regulating bolt
15 are fixed on seal holder ring I 4, and both ends are pressed on pressing plate I 6, and the effect of flat spring I 7 is as barrel body rotation produces radially
During bounce, there is appropriate thrust to pressing plate I 6 all the time.Due to the elasticity of packing 3 itself and the elasticity of flat spring I 7, packing 3 begins
Whole hold-down barrel is cylindrical, ensure that the cylindrical sealing between packing 3 of cylinder.Packing 3 is to solid particle in kiln and High Temperature Gas
Body has preferable buffer action.
Packing 3 seal outside, set one of rubber seal ring 9 seal, rubber seal ring 9 it is cylindrical on, equally
There is provided pressing plate II 10 and the hold-down mechanism of flat spring II 11, is deformed to compensate rubber seal ring 9 caused by cylinder circular runout,
So that rubber seal ring 9 is pressed on cylinder periphery and has good resilience all the time.Install and adjust on seal holder ring II 5
Save bolt 15, the middle part of flat spring II 11 is fixed on regulating bolt end, regulating bolt, certain to flat spring II 11 during 1 installation
Pretightning force so that during cylinder circular runout, packing 3 and rubber seal ring 9 do not depart from cylinder external cylindrical surface all the time；And in packing 3
After being worn with rubber seal ring 9, the thrust of flat spring II 11 is reconciled by screwing regulating bolt, it is ensured that outside packing 3 and cylinder
Always there is appropriate thrust between circle rubbing surface, rubber seal ring and cylinder rubbing surface, it is ensured that sealing effectiveness.When packing has one
When wearing surely, regulating bolt crush so that flat spring, pressing plate persistently compress packing on cylinder is cylindrical.
Rubber seal ring is more structures of lip 13, and containing 2-6 bars lip 13, the length of lip 13 differs, resilience have compared with
Wide scope, can so ensure there is 1 to 2 lip all the time that hold-down barrel is cylindrical all the time and has good resilience.
Several oil filling pipes 14 of spaced set, oil filling pipe 14 pass through between pressing plate II 10 on the circumference of seal holder ring II 5
Gap, connected by the gap between the circular hole on rubber seal ring 9, and the lip 13 of rubber seal ring 9, set multiple spot
Centralized lubricating system at regular time and quantity by gap of the oil filling pipe to sealing ring lip, between lip and cylinder periphery fill moisten
Consistent lubricant, lubricating grease both play sealing function, reduce the friction of rubber seal ring again, extend the service life of rubber seal ring.
