초록 ▼

This invention relates to an improved method and device for removing liquid from a moving surface such as a continuous metal sheet or strip. The invention has particular application to the removing of lubricant and/or coolant from sheet or strip in a rolling operation or the backup rolls of the rolling mills. The invention comprises a vacuum unit to remove most of the liquid from the moving surface, an air knife to drive the liquid remaining on the surface toward the vacuum unit, and a vent maintained at a pressure intermediate between the low pressure of the vacuum unit and the high pressure of the air knife to minimize eddy current formation in the gas flow from the air knife to the vacuum unit. Eddy currents can cause the redeposition of liquid onto the essentially dry sheet or strip.

A method of removing a liquid from the surface of a moving strip comprising the steps of: (A) Directing the moving strip having liquid on a surface thereof past and in close proximity to a liquid removing device disposed across the width of said strip; (B) Establishing and maintaining across the width of the surface of the moving strip a partial vacuum through at least one slotted opening disposed across and adjacent the moving strip in order to aspirate and remove the bulk of the liquid on and from the surface of the moving strip; (C) Next moving the strip past a curtain of a high velocity gas while directing said gas in the form of a curtain generally perpendicular to and across the width of the moving strip\s surface so that a substantial portion of the perpendicularly directed gas curtain is redirected upon impact with the said strip\s surface parallel thereto and countercurrent to the movement thereof to remove liquid remaining on the moving surface; and (D) During passage of said strip from said partial vacuum area to said curtain of high velocity gas preventing the formation of eddy currents in the high velocity gas curtain by establishing a controlled confined gaseous stream and introducing said stream into the gas of the gas curtain intermediate said partial vacuum area and said high velocity gas curtain and maintaining said gaseous stream at a pressure intermediate the pressure level of the gas in the partial vacuum area and the pressure level of the gas in the high velocity gas curtain.
