Den Gegenstand der Erfindung bildet ein Verfahren zum Entwässern von Torf ο. dgl. unter gleichzeitiger Anwendung von Preßdruck und Vakuum oder unter abwechselnder An-Wendung von Preßdruek und Vakuum, wobei der Preßdruek und das Evakuieren oder jeder Arbeitsvorgang für sich zeitweise unterbrochen werden.The subject of the invention is a method for dewatering peat ο. like with simultaneous application of pressure and vacuum or with alternating application of press pressure and vacuum, with press pressure and evacuation or each Work process can be temporarily interrupted.
Das Wesen der Erfindung besteht darin,The essence of the invention is
ίο daß der gleichzeitige Preßdruek und das Evakuieren oder jeder Arbeitsvorgang für sich während der Unterbrechung auf Null oder nahezu auf Null bzw. Atmosphärendruck zurückgehen. ίο that the simultaneous pressure and evacuation or each work process for itself during the interruption to zero or go back to almost zero or atmospheric pressure.
Die bisher bekannt gewordenen Verfahren dieser Art haben nicht befriedigende Ergebnisse gezeitigt, denn es hat sich herausgestellt, daß die in der Masse enthaltene Feuchtigkeit ^ bei Anwendung eines auch noch so starken Druckes aus der Masse nicht herausgepresst wird, sondern teilweise in den geknickten Zellen der Masse eingeschlossen bleibt.The methods of this type which have become known to date have not produced satisfactory results timed, because it has been found that the moisture contained in the mass ^ not squeezed out of the mass when applying pressure, no matter how strong but remains partially enclosed in the kinked cells of the mass.
Dieser Nachteil soll durch die Erfindung beseitigt werden.This disadvantage is to be eliminated by the invention.
Bei Ausübung des Verfahrens gemäß der Erfindung wird erreicht, daß die beim, ersten Zusammenpressen der Masse etwa umgeknickten und nicht ganz aufgebrochenen, die Feuchtigkeit enthaltenden Zellen beim Zurückgehen des Druckes auf Null oder nahezu Null wieder ihre normale Lage einnehmen, worauf dann beim nächstfolgenden Preßdruek ein anderer Teil derselben aufgebrochen und ausgepreßt wird.When practicing the method according to the invention it is achieved that the first Compressing the mass if it is bent or not completely broken up, the moisture containing cells when the pressure is reduced to zero or near zero resume their normal position, whereupon another press at the next press Part of the same is broken open and squeezed out.
, Selbstverständlich wird der Erfolg des neuen Verfahrens um so vollkommener sein, je öfter die Unterbrechung der Preß wirkung stattfindet bei ein und derselben gesamten Zeitdauer der Behandlung der Masse.Of course, the more often the new procedure will be the more successful the interruption of the pressing action takes place at one and the same total period of time Treatment of the crowd.
Durch die Wirkung des Vakuums wird diejenige des Preßdruckes insofern erhöht, als die durch die Pressung aus den Zellen herausgedrückte Feuchtigkeit rascher abgesaugt wird, wobei das Zurückgehen des Vakuums auf Null oder nahezu Null das Zurückkehren der Zellen in ihre normale Lage erleichtert.By the effect of the vacuum that of the pressing pressure is increased insofar as the moisture squeezed out of the cells by the pressure is sucked off more quickly, with the return of the vacuum to zero or near zero the return of the cells relieved into their normal position.
Auf der Zeichnung ist eine Vorrichtung zur Ausübung des neuen Verfahrens beispielsweise in Fig. ι in einem lotrechten Schnitt und inIn the drawing, a device for performing the new method is for example in Fig. Ι in a vertical section and in
Fig. 2 in einer Draufsicht bei abgenommenem Deckel dargestellt.Fig. 2 is shown in a plan view with the cover removed.
Die Vorrichtung besteht aus zwei ineinanderliegehden Behältern α und b, zwischen welchen ein Hohlraum c vorgesehen ist. Der Behälter a ist an den Seitenwänden und am Boden durchlöchert und trägt in der Richtung der Pressung verlaufende durchlöcherte Röhren d, die in den Hohlraum c zwischen den Behältern α und b münden, e ist der im inneren Behälter α wirkende durchlöcherte Kolben zur Ausführung der mechanischen Pressung; f ist ein Anschlußstutzen für die Erzeugung des Vakuums im Innern des Behälters b, während g ein Ablaßstutzen für das Wasser ist.The device consists of two nested containers α and b, between which a cavity c is provided. The container a is perforated on the side walls and at the bottom and carries perforated tubes d running in the direction of the compression, which open into the cavity c between the containers α and b , e is the perforated piston acting in the inner container α for the execution of the mechanical Pressing; f is a connection piece for creating the vacuum inside the container b, while g is a drainage piece for the water.
