In dress inner groovy, described sealing ring is positioned at described sealing ring and installs inner groovy, and described sealing ring is corresponding to described guide ring
Position is provided with indent escape groove, and a sidewall of described sealing ring is close to the respective side outer wall of described other pressure roller, described sealing ring
Another sidewall be close to correspondence position described sealing ring install inner groovy end wall, it is right that the outer circumferential surface of described sealing ring is close to
The outer shroud inwall of inner groovy installed by the described sealing ring answering position.
It is further characterized by
Described sealing ring installs the back-up ring structure being provided with convex on the outer shroud inwall of inner groovy, the outer shroud of described sealing ring
Side face is provided with indent outer groove corresponding to back-up ring structure, and the width of described indent outer groove is more than the width of described back-up ring structure
Degree, the sidewall of the described indent outer groove of correspondence position, back-up ring are close in the side of the close described other pressure roller of described back-up ring structure
Structure and indent outer groove make material cannot enter in bearing along the direction, it is ensured that sealing property；
Described sealing ring is provided with escape groove corresponding to the position of described bearing set screw, it is simple to bearing set screw
Install.
After using technique scheme, a sidewall of sealing ring is close to the respective side outer wall of described other pressure roller, described sealing
Another sidewall of ring is close to the end wall of the described sealing ring installation inner groovy of correspondence position, and the outer circumferential surface of described sealing ring is close to
The outer shroud inwall of inner groovy installed by the described sealing ring of correspondence position, and sealing ring is provided with corresponding to the position of described guide ring
Indent escape groove, guide ring and indent escape groove ensure that material cannot pass through sealing ring and enters in bearing, it makes side
In the course of the work, material will not enter in bearing pressure roller, and then guarantees the normal work of other pressure roller.
Accompanying drawing explanation
Fig. 1 is front view structural representation of the present utility model；
Fig. 2 is partial enlargement structural representation at the A of Fig. 1；
In figure, the title corresponding to sequence number is as follows:
Other pressure roller 1, installation axle 2, bearing 3, mounting post 4, guide ring 5, sealing ring 6, sealing ring install inner groovy 7, indent
Escape groove 8, back-up ring structure 9, indent outer groove 10, bearing set screw 11, escape groove 12.
Detailed description of the invention
The sealing structure of a kind of filter, is shown in Fig. 1, Fig. 2: it includes that other pressure roller 1, other pressure roller 1 are set in installation axle 2, peace
Dress axle 2 is supported in two mounting posts 4 of frame by the bearing 3 of both sides, and bearing 3 is positioned at the position, outside of the mounting post 4 of correspondence
Putting, in the other pressure roller 1 cavity between two mounting posts 4, other pressure roller 1 is respectively arranged with projection towards the both sides of bearing 4
Guide ring 5, the central shaft of guide ring 5 coincides with the central shaft installing axle 2, installs axle 2 corresponding to other pressure roller 1 and corresponding installation
Being set with sealing ring 6 at the interstitial site of post 4, mounting post 4 has sealing ring installation inner groovy 7 corresponding to the side of guide ring 5,
The raised position of guide ring 5 is goed deep into the sealing ring of correspondence position and is installed in inner groovy 7, and sealing ring 6 is positioned at sealing ring and installs indent
In groove 7, sealing ring 6 is provided with indent escape groove 8 corresponding to the position of guide ring 5, and a sidewall of sealing ring 6 is close to other pressure roller 1
Respective side outer wall, another sidewall of sealing ring 6 be close to correspondence position sealing ring install inner groovy 7 end wall, sealing ring 6
Outer circumferential surface is close to the outer shroud inwall of the sealing ring installation inner groovy 7 of correspondence position.
Sealing ring installs the back-up ring structure 9 being provided with convex on the outer shroud inwall of inner groovy 7, the outer circumferential surface of sealing ring 6
Back-up ring structure is provided with indent outer groove 10, and the width of indent outer groove 10 is tied more than the width of back-up ring structure 9, back-up ring
The sidewall of indent outer groove 10 correspondence position, back-up ring structure 9 and indent outer groove 10 are close in the side near other pressure roller 1 of structure 9
