Abstract

Bei einem Verfahren und einer entsprechenden Vorrichtung zum Abführen des innerhalb der Schlaufe eines umlaufenden Entwässerungssiebes (12) eines Formers, insbesondere eines Doppelsiebformers, einer Papiermaschine anfallenden Siebwassers (16) wird das Siebwasser durch ein innerhalb der Schlaufe angeordnetes Sammelbecken (14) aufgefangen, das aufgefangene Siebwasser durch Absaugen des Bereichs oberhalb des Sammelbeckens noch innerhalb der Siebschlaufe von der Luft getrennt und das Siebwasser über wenigstens einen sich an das Sammelbecken anschließenden, unterhalb dessen Wasserspiegels (N1) liegenden Kanal (24) aus dem Sammelbecken entfernt.

Figure 00000001
In a method and a corresponding device for removing the white water (16) accumulating within the loop of a circulating dewatering screen (12) of a former, in particular a twin wire former, of a paper machine, the white water is collected by a collecting basin (14) arranged inside the loop, the collected White water is still separated from the air within the sieve loop by suctioning off the area above the collecting basin and the white water is removed from the collecting basin via at least one channel (24) adjoining the collecting basin and below its water level (N 1 ).
