And the occasion such as slag has obtained widely applying；Grinding roller is as Vertical Mill core component, its sealing
The quality of energy directly affects the normal operation of Vertical Mill；Traditional grinding roller sealing using aeroseal or
The method of seal sealing, aeroseal need to use seal fan and pipeline, and cost is higher；And
Using seal, such as graphite packing sealing or oil sealing sealing, it is short service life to be present, sealing
Effect is poor, changes the problems such as complicated.
The content of the invention
The technical problems to be solved by the invention are to provide a kind of easy processing, it is not necessary to change, seal
Novel vertical mill grinding-roll sealing device of good performance.
In order to solve the above technical problems, the present invention realizes as follows：Design is a kind of new
Type vertical mill grinding roll sealing device, it is by A sealing rings, hold-down bolt, felt collar, lubricating cup, B
Sealing ring and pressing plate composition；B sealing rings in a ring and are sheathed on shaft of grinding roller, its rear portion with it is upper
Rocking arm forms contact connection, and B sealing rings underside of forward is radially interval with ring shaped axial sealing
Groove；A sealing rings in a ring and are sheathed on shaft of grinding roller, and its front end is provided with and axial seal grooves phase
The ring shaped axial sealing tooth of cooperation；Also be arranged with felt collar on A sealing rings front end, felt collar bottom surface with
A sealing rings leading exterior surface, which is formed, to be tightly connected；The ring-like pressing plate that felt collar is provided with by its right side
Form and be fastenedly connected with B sealing rings with hold-down bolt；A sealing rings on shaft of grinding roller contact surface with going back
It is interval with radial seal groove.
Further, in order to preferably realize sealing, the B sealing rings contact with shaft of grinding roller
A sealing ring is also equipped with face.
Further, in order to preferably realize lubrication and sealing, gone back inside the B sealing rings
Provided with the oil duct being connected with axial seal grooves, opening of the oil duct in B sealing rings upper end is pacified
Equipped with lubricating cup.By lubricating cup toward lubricating grease is filled in gap, so as to reach the purpose of sealing.
Further, in order to preferably realize lubrication and sealing, fill and set in the axial seal grooves
There is lubricating grease.
The positive effect of the present invention：In technical solution of the present invention, there is provided a kind of easy processing, it is not necessary to
Change, the novel vertical mill grinding-roll sealing device of favorable sealing property；And its cost is relatively low and does not relate to
And influence problem of the sealed material to sealing effectiveness, and be applied in engineering project, obtain
Good effect.
