Technical field
The present invention relates to a kind of grinding roller pull rod seal device.
Background technology
In powder processing production equipment, each grinding roller both sides of usual Vertical Mill are designed with pull bar, every pull bar it is another
One end is ined succession hydraulic cylinder, pull bar by mill it is outdoor through water conservancy diversion pedestal 12 to enter mill indoor, and pull bar is controlled by hydraulic means, come
Realize the rising of grinding roller and push.Grinding machine can produce powder granule 14 in process of lapping, to prevent powder granule from pull bar and lead
Spilt in gap between stream pedestal, because the lifting of grinding roller is driven by pull bar, grinding roller pull bar can lift simultaneously when working
Also move forward and backward, pull bar is dynamic relative to water conservancy diversion pedestal, and water conservancy diversion pedestal is static, and gap between the two is real
Now reliably sealing, sealing difficulty is big, and the sealing effectiveness of common sealing such as rubber-like is poor, and powder drains to mill outdoor, seriously
Pollute production environment.
The content of the invention
The present invention has made improvements in view of the above-mentioned problems of the prior art, i.e., the technical problems to be solved by the invention are
A kind of grinding roller pull rod seal device is provided, can meet that pull bar moves, can ensure reliably to seal again, to realize cleaning life
Production.
In order to solve the above-mentioned technical problem, the technical scheme is that：A kind of grinding roller pull rod seal device, sealing dress
Put on the pull bar of grinding roller of vertical mill, including one enters the indoor seal pipe of mill, the pull bar from mill is outdoor through water conservancy diversion pedestal
Through seal pipe, the ring packing pressing plate being set on pull bar, the sealing clamp are provided with the seal pipe top nozzle
External diameter be more than seal pipe internal diameter, the pull bar top is provided with the elasticity being pressed in sealing clamp all the time on the seal pipe mouth of pipe
Pressurizing unit.
Further, the internal diameter of the seal pipe is more than pull bar external diameter, so that gap between the two meets that pull bar is rising
Drop moves forward and backward required space.
Further, the sealing clamp is made using stainless steel plate.
Further, the elastic squeezing unit includes a retainer ring being set on pull bar, in addition to one is arranged on admittedly
Determine the spring between ring and sealing clamp.
Further, it is provided with lock-screw on the fixed ring-side wall.
Further, the sealing clamp madial wall is in the arc protruded to center position.
Further, the internal diameter of the sealing clamp is equal with pull bar external diameter.
Further, the seal pipe is weldingly fixed on water conservancy diversion pedestal.
Further, the internal diameter of shown seal pipe and pull bar external diameter ratio are 1.6:1.
Compared with prior art, the invention has the advantages that：
1st, special sealing structure, the leakage of powder can be prevented well, realizes clean manufacturing；
2nd, the steel plate end face gluing, sealing used, the problem of without General Purpose Rubber seal aging, good reliability, the longevity is used
Life length；
3rd, it is simple in construction, it is easily fabricated；
4th, good sealing effect, no powder leakage, the phenomenon that system will not leak out in process of production, beneficial to product matter
The stability of amount, while also a saving the energy consumption of blast system；
5th, clean manufacturing, environmental protection.
The present invention will be further described in detail with reference to the accompanying drawings and detailed description.

Embodiment
Embodiment one：As shown in figs. 1 to 6, a kind of grinding roller pull rod seal device, the sealing device are arranged on the grinding roller of Vertical Mill 1
On 11 pull bar 13, including one enters the indoor seal pipe of mill from mill is outdoor through water conservancy diversion pedestal 12, and the pull bar passes through seal pipe
2, the ring packing pressing plate 3 being set on pull bar is provided with the seal pipe top nozzle, and the external diameter of the sealing clamp is big
In the internal diameter of seal pipe, the pull bar top is provided with the elasticity extruding dress being pressed in sealing clamp all the time on the seal pipe mouth of pipe
Put.
In the present embodiment, the internal diameter of the seal pipe is more than pull bar external diameter, so that gap between the two meets that pull bar exists
Lifting moves forward and backward required space.The internal diameter of shown seal pipe is 1.6 with pull bar external diameter ratio:1.
In the present embodiment, the sealing clamp is made using stainless steel plate.The problem of without General Purpose Rubber seal aging,
Good reliability, service life length.
In the present embodiment, the elastic squeezing unit includes a retainer ring 5 being set on pull bar, in addition to one is arranged on
