Vertical Mill is as a kind of main milling equipment, at grinding raw material, cement, coal dust, slag
And the occasion such as slag has obtained applying widely；Grinding roller as Vertical Mill core component, its sealing
The quality of energy directly affects the properly functioning of Vertical Mill；Traditional grinding roller seal use aeroseal or
The method that sealing member seals, aeroseal needs with seal fan and pipeline, relatively costly；And
Use sealing member, such as graphite packing sealing or oil sealing sealing, all there is service life short, seal
Weak effect, changes the problems such as complicated.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of easily processing, it is not necessary to change,
The Novel vertical mill grinding-roll sealing device of favorable sealing property.
For solving above-mentioned technical problem, this utility model realizes as follows: design one
Kind of Novel vertical mill grinding-roll sealing device, it is by A sealing ring, hold-down bolt, felt collar, lubricating cup,
B sealing ring and pressing plate composition；B sealing ring ringwise and is sheathed on shaft of grinding roller, its rear portion with
Upper rocker arm constitutes contact and connects, and it is close that B sealing ring underside of forward is radially interval with ring shaped axial
Sealing groove；A sealing ring ringwise and is sheathed on shaft of grinding roller, and its front end is provided with and axial seal groove
The ring shaped axial matched seals tooth；Felt collar, felt collar bottom surface also it is arranged with on A sealing ring front end
Constitute with A sealing ring leading exterior surface and be tightly connected；Felt collar is ring-like by be provided with on the right side of it
Pressing plate and hold-down bolt are fastenedly connected with B sealing ring composition；A sealing ring and shaft of grinding roller contact surface
On be also interval with radial seal groove.
Further, in order to preferably realize sealing, described B sealing ring contacts with shaft of grinding roller
A sealing ring it is also equipped with on face.
Further, in order to preferably realize lubrication and seal, described B sealing ring is internal also
It is provided with the oil duct being connected with axial seal groove, the oil duct opening part peace in B sealing ring upper end
Equipped with lubricating cup.In gap, fill grease by lubricating cup, thus reach the purpose sealed.
Further, in order to preferably realize lubrication and seal, fill in described axial seal groove and set
There is grease.
Good effect of the present utility model: in technical solutions of the utility model, it is provided that one easily adds
Work, 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 be not related to the sealed material problem that affects on sealing effectiveness, and answered in engineering project
With, achieve good effect.
