Die Anlage nach den Fig. 1 und 2 arbeitet in bezug auf den Preßvorgang taktweise. Zu dieser Anlage gehört zunächst eine längs eines Verfahrabschnittes auf Laufschienen 1 oder dergleichen hinundher bewegbare Entwässerungsplattenpresse 2 mit Pressenoberteil 3 und Pressenunterteil 4 sowie mit oberer und unterer Pressenplatte 5. Zur Anlage gehört fernerhin ein durch die Entwässerungsplattenpresse 2 und über stationär angeordnete Umlenktrommeln 6 geführtes, angetriebenes Siebband 7 für die Aufnahme der Feststoffmatte M. Dieses Siebband 7 mag weiter links von der Figur mit dem Preßgut bestreut werden und eine Benetzungsstation für das Preßgut passieren, was nicht gezeichnet wurde. Man erkennt fernerhin ein endlos um das Pressenunterteil 4 geführtes über Umlenkeinrichtungen 8 umlaufendes Lattenrostband 9, welches zwischen Siebband 7 und unterer Pressenplatte 5 verläuft. Dazu wird auf den vergrößerten Ausschnitt B in der Fig. 1 verwiesen. In diesem erkennt man auch ein endlos um das Pressenunterteil 4 geführtes, über Umlenkeinrichtungen 10 umlaufendes Abdichtungsband 11, welches zwischen Lattenrostband 9 und unterer Pressenplatte 5 verläuft. Die Anlage arbeitet so, daß die Streueinrichtung, die das Siebband 7 mit dem Preßgut belegt, kontinuierlich arbeitet. Folglich ist die Anordnung fernerhin so getroffen, daß die Entwässerungsplattenpresse 2 beim Preßvorgang nach Maßgabe der Transportgeschwindigkeit des Siebbandes 7 verfahrbar und danach zum Pressen eines folgenden Abschnittes im geöffneten Zustand zurückbewegbar ist. Das wurde durch einen Doppelpfeil im Pressenoberteil 3 der Fig. 1 verdeutlicht.The system according to FIGS. 1 and 2 operates intermittently with respect to the pressing process.
