Abstract
An arrangement of equipment in connection with a variable crown roll provided with loading shoes to prevent foaming of fluid. The arrangement includes a separate guide and a face that guides the fluid in order to guide the fluid smoothly away from the inner face of the roll mantle of the roll and into a collecting trough.
Claims20
An arrangement of equipment in connection with a variable-crown roll provided with loading shoes for the prevention of foaming of fluid, characterized in that the arrangement of equipment comprises a separate guide (13) and therein a face (13a) that guides the fluid smoothly away from the inner face (11′) of the roll mantle (11) and into a collecting trough (19), in which arrangement of equipment the guide (13) has been fitted separate from the loading shoes (20).
An arrangement of equipment as claimed in the preceding claim, characterized in that the stationary axle (12) includes a piston device (16,17), by whose means the guide (13) is pressed into contact with the inner face (11′) of the roll mantle.
An arrangement of equipment as claimed in the preceding claim, characterized in that the fluid space (17) of the piston device has been formed into the stationary axle (12), and the piston (16) has been fitted into said fluid space (17), and further the piston (16) is coupled with the guide (13).
An arrangement of equipment as claimed in the preceding claim, characterized in that the spring (22,24) has been fitted around the spindle (21,25), which spindle (21,25) is fitted by means of a glide fitting in the hole (n) in the stationary axle (12) or in the loading shoe (20), in which connection the spindle (21,25) can be displaced in a way similar to a slide, and in which connection the spring (22,24), when it acts between the guide (13) and the stationary axle (12) or between the guide (13) and the loading shoe (20), presses the guide (13) into contact with the inner face (11′) of the roll mantle.
An arrangement of equipment as claimed in the preceding claim, characterized in that the spindle (21) has been fitted in connection with the side face of the displaceable loading shoe (20), in which connection the guide (13) coupled with the spindle (21) always follows the deformations of the roll mantle produced by the loading shoe (20).
An arrangement in a variable-crown roll having loading shoes, a stationary axle from which the loading shoes project and bearing means supporting the roll from an inner face of a roll mantle, the arrangement comprising:
- a fluid guide structured and arranged in connection with the inner face of the roll mantle, said fluid guide having a face portion thereon,
- a trough located substantially beneath said fluid guide, said face portion of said fluid guide structured and arranged to guide a fluid away from the inner face of the roll mantle and into said trough.
