Definitions

  • the present invention relates to cleaning apparatus and, more particularly, to improved apparatus for applying liquid onto and/or cleaning foreign material from a cylindrical surface while it is moving at a rapid rate of speed.
  • FIG. 1 portrays diagrammatically one arrangement of equipment which has been satisfactorily employed for practicing the present invention.
  • FIGS. 2 and 3 illustrate modifications of the embodiment illustrated in FIG. 1.
  • Roll 11 may be a paper machine roll or it may be a backing roll of a coating machine or any other type of roll which may require constant or frequent cleaning to keep the surface of the roll free of undesirable foreign material such as wet broke, coating composition, or other miscellaneous matter that would produce undesirable characteristics in the finished paper.
  • both of these objects are achieved by providing a piece of open cell or porous sponge-like material 12 enclosed in a suitable housing. Disposed within or in contact with the sponge-like material is a perforate conduit 14 for uniformly distributing a liquid cleaning material such as water or the like into the sponge-like material at a rate regulated by valve 14a from a suitable source (not shown).
  • the sponge-like material contacts the rotating surface of roll 11 and applies thereon a regulated quantity of liquid which is uniformly distributed onto the rotating roll surface a continuous film extending along the entire extent of the roll.
  • a doctor 16 is spaced apart from the sponge-like material 12 in the direction of rotation of roll 11 and functions to maintain a film 15 of the liquid solvent uniformly distributed along the face of roll 11 between doctor 16 and he sponge-like material. Concomitantly the doctor removes from said surface the film of liquid containing said foreign material and causes the liquid containing said material to overflow at the ends of the roll. This overflow liquid is collected and removed by any convenient means (not shown).
  • the apparatus of the invention as illustrated and described has been found to be very satisfactory and effective for cleaning the surface of roll 11 and removing foreign material therefrom. Additionally, due to the relative movement between the surface of roll 11 and sponge-like material 12, the sponge-like material exerts a scrubbing action which is very effective in cleaning the surface of the roll. Unexpectedly, the film 15 remains in contact with the surface of roll 11 at surface speeds ranging, for example, up to about 3,500 feet per minute on a 36-inch diameter roll even though, it can be shown, that a drop of liquid traveling at such speed on the roll surface is subjected to an acceleration many times that of gravity. It is believed that use of apparatus of the present invention results in the cooperative combination of cohesive and adhesive forces of the thin continuous film of the liquid with the forces resulting from a change in the momentum of said liquid which oppose the centrifugal force resulting from said rotation.
  • the uppermost edge of docotr 16 is disposed adjacent to and/or may be connected to housing 13.
  • FIG. 3 differs from the embodiment of FIG. 2 in that the lower edge of doctor 16 is not in contact with the roll surface but is closely spaced therewith.
  • the cleaning action of the spongelike material 12, solvent film 15 and doctor 16 is substantially, as described above, in connection with the foregoing embodiments.
  • conduit 14 may be disposed outside housing 13 with its perforations in registry with openings in housing 13 and directed inwardly toward sponge-like material 12.
  • sponge-like includes resilient materials such as open celled porous polyurethane, foam rubber, real sponge and the like. It is desirable, although not essential, that such sponge-like material be somewhat resistant to abrasion to withstand the rubbing engagement with the roll surface.
  • Apparatus for cleaning the surface of a rotating roll wherein said surface is moving at speeds ranging from about 250 to and including about 3,500 feet per minute comprising in combination means forming and uniformly distributing a continuous film of film-forming liquid on said moving surface,
  • said forming and distributing means includes perforate conduit means connected to said supply means and uniformly delivering said liquid into the interior of open-celled cellular and sponge-like material positioned adjacent and in rubbing engagement with said surface and extending lengthwise relative to said roll.
  • said cellular and sponge-like material is polyurethane.
