Arrangement for removing oil in a roll

Abstract

The roll comprises a stationary support construction ( ) and a roll mantle ( ) revolving around the construction, which mantle is supported from its inner face ( ′) on the support construction ( ) by at least one hydraulically loaded loading member ( ), by which the roll mantle ( ) is loaded against a backup roll ( ) which forms a nip (N) with the roll. The oil removing arrangement comprises an oil collecting equipment ( ) fitted in the space between the outer face ( ″) of the support construction ( ) and the inner face ( ′) of the roll mantle ( ), in which oil collecting equipment there is an oil guide plate ( ) which is supported at least on the support construction ( ), which is arc-shaped in the direction of the circumference and which forms a first oil guide face. At the lateral edges of the oil guide plate ( ), there are radial side walls ( ) directed towards the support construction, and at the curved rear edge there is a curved rear wall ( ). In the space between the oil collecting equipment ( ) and the outer face ( ″) of the support construction ( ), a flow passage is formed, along which the oil present in the roll is guided into oil guide arrangements passing out of the roll.
