A kind of the problems such as big two rotate against body and carry out sealing and can cause leakage, there is provided the rotatory sealing that axial-radial is automatically adjusted
Mechanism.
To achieve the above object, institute is the present invention using technical solution：The rotation that a kind of axial-radial is automatically adjusted
Sealing mechanism, including static housing and rotary barrel, also include ceramic cotton, transition ring flat-plate and support ring frame, described pottery
Porcelain cotton one end is fixed on static housing by cotton pressing plate, and the ceramic cotton other end is fixed on transition rings by cotton pressing plate
Plate side, described transition ring flat-plate is circumferentially provided with multiple connecting springs, and transition ring flat-plate passes through multiple connecting springs and support ring
The inner ring of frame is connected, and multiple herein is three or more than three, and described rotary barrel is fixed by spring press roll component
In transition ring flat-plate opposite side.
The KmTBCr12 cast iron layers of anticorrosive anti-wear are provided between described transition ring flat-plate and rotary barrel contact surface.
Described spring press roll component includes screw rod, pressure roller shaft, pressure roller and leading screw axle sleeve, and described screw rod is welded on transition
On ring flat-plate, the roller of the pressure roller is connected by the axle of pressure roller shaft with leading screw axle sleeve, and described leading screw axle sleeve is hollow ring set,
Leading screw axle sleeve is nested with screw rod near transition ring flat-plate end, and the described screw rod other end is provided with bolt, described leading screw axle sleeve and
Spring is provided between bolt.
Compared with prior art, the beneficial effects of the invention are as follows：

Specific embodiment
Below in conjunction with brief description of the drawings, the present invention is described in further detail with specific embodiment.
Referring to Fig. 1 to Fig. 2, the rotary sealing mechanism that a kind of axial-radial is automatically adjusted, including static housing 1, rotating cylinder
Body 6, ceramic cotton 3, transition ring flat-plate 4 and support ring frame 7.Described one end of ceramic cotton 3 is fixed on fixation by cotton pressing plate 2
On casing 1, the other end of ceramic cotton 3 is fixed on the side of transition ring flat-plate 4 by cotton pressing plate 2.Described transition ring flat-plate 4 is circumferential to be set
It is equipped with multiple connecting springs 8, transition ring flat-plate 4 is connected by multiple connecting springs 8 with the inner ring of support ring frame 7, herein many
Individual is three or more than three；I.e. excessive ring flat-plate 4 is suspended in the middle of support ring frame 7 in the presence of the pullling of connecting spring 8.Institute
The rotary barrel 6 stated is fixed on the opposite side of transition ring flat-plate 4 by spring press roll component 5, that is, cause rotary barrel 6 in spring pressure roller
Component 5 is close to the opposite side of transition ring flat-plate 4 under fixing.Therefore, static housing 1 and rotating box 6 are in ceramic cotton 3, transition
In the presence of ring flat-plate 4, support ring frame 7 and spring press roll component 5, foring one can be axially and radially all self-adjustable close
Envelope system；And ceramic cotton 3 is the resistant to elevated temperatures material with certain flexibility, when larger relative displacement is produced, ceramic wool
Cloth 3 can keep good being tightly connected property.
The KmTBCr12 cast iron layers of anticorrosive anti-wear are provided between described transition ring flat-plate 4 and the contact surface of rotary barrel 6, and
KmTBCr12 cast irons are with acidproof Corrosive Materia, so as to increased service life.
Referring to Fig. 3, described spring press roll component 5 includes screw rod 11, pressure roller shaft 13, pressure roller 14 and leading screw axle sleeve 9.It is described
