Abstract

Bandpreßeinheit (1) und Verfahren zum Betrieb einer Bandpreßeinheit mit einem im Bereich eines Preßspaltes (4) durch Stützmittel (9) gelagerten umlaufenden Preßmantel (11), wobei ein aufbereitetes Fluid (12) zum Kühlen des Preßmantels (11) und zum Schmieren des zwischen dem Preßmantel (11) und den Stützmitteln (9) gebildeten Gleitlagers auf den Preßmantel aufgebracht und Fluid (12) an einer Abstreifstelle vom Preßmantel abgenommen wird, wobei das durch die Kühlung des Preßmantels (11) erwärmte Fluid (12) an der Abstreifstelle vollständig vom Preßmantel (11) abgenommen wird, bevor in Laufrichtung des Preßmantels (11) hinter der Abstreifstelle aufbereitetes Fluid (12) aufgebracht wird, um ein Vermischen des erwärmten Fluids mit dem aufbereiteten Fluid zu verhindern. Außerdem wird eine Fluidabstreifvorrichtung (13) für die Bandpreßeinheit mit einem direkt in Kontakt mit dem Fluid stehenden Abstreifelement und mit Anpreßmitteln (82) beschrieben, die das Abstreifelement (51) an einen Preßmantel (11) andrücken, wobei der Querschnitt des Abstreifelements (51) im Bereich des Preßmantels kreis-, ellipsenförmig oder eine beliebig daran angenäherte Freiform ist.

Figure 00000001
Belt press unit (1) and method for operating a belt press unit with a circumferential press jacket (11) mounted in the area of a press nip (4) by means of support means (9), a processed fluid (12) for cooling the press jacket (11) and for lubricating the between the press jacket (11) and the support means (9) formed slide bearing is applied to the press jacket and fluid (12) is removed from the press jacket at a stripping point, the fluid (12) heated by the cooling of the press jacket (11) being completely removed from the stripping point Press jacket (11) is removed before processed fluid (12) is applied behind the stripping point in the running direction of the press jacket (11) in order to prevent mixing of the heated fluid with the prepared fluid. In addition, a fluid wiping device (13) for the band press unit is described with a wiping element which is in direct contact with the fluid and with pressing means (82) which press the wiping element (51) against a press jacket (11), the cross section of the wiping element (51) in the area of the press jacket is circular, elliptical or any free form approximated to it.
