eines Filters hindurchgedrückt wird.a filter is pushed through.
Patentiert im Deutschen Reiche vom 28. Mai 1910 ab.Patented in the German Empire on May 28, 1910.
Den Gegenstand der vorliegenden Erfindung bildet ein Verfahren zum Entwässern von Schlamm in der Weise, daß derselbe ununterbrochen durch die zentrale Öffnung eines Filters hindurchgedrückt wird. Das Neue bei diesem Verfahren besteht nun darin, daß als Filtermaterial ein Filterstein benutzt wird, der in an sich bekannter Weise an der Außenseite durch eine starke Umhüllung vorThe subject of the present invention is a method for dewatering Mud in such a way that the same continuously through the central opening of a Filter is pushed through. The novelty in this process is that as Filter material, a filter stone is used, which is in a known manner on the Outside by a strong cover
ίο dem Zerspringen gesichert und um den zentralen Schlammdurchfluß mit die Flüssigkeit abführenden Kanälen versehen ist.ίο secured against shattering and around the central Mud flow is provided with the liquid discharging channels.
Die kontinuierliche Entwässerung schlammiger Massen bietet insofern Schwierigkeiten, als die Filtersteine in doppelter Weise beansprucht werden, einmal senkrecht zur Vorwärtsbewegung der Schlammasse durch den Druck, welche die Entwässerung bewirkt, gleichzeitig aber auch durch den Reibungsdruck, welcher durch die Vorwärtsbewegung der Schlammassen entsteht. Diese besondere Kräftebeanspruchung hatte zur Folge, daß die gewöhnlichen Filterkörper keine Verwendung finden konnten.The continuous dewatering of muddy masses presents difficulties insofar as when the filter stones are stressed in two ways, once perpendicular to the forward movement the sludge mass due to the pressure that causes the dewatering, but at the same time also due to the frictional pressure, which is created by the forward movement of the sludge masses. This particular stress had the consequence that the ordinary filter bodies could not be used.
Aber die Anwendung der Filtersteine für den vorliegenden Zweck bietet insofern besondere Vorteile, als bei der Entwässerung von Abwasserschlamm eine vollständige Bakterienreinigung stattfindet, so daß das Wasser beinahe bakterienfrei den Apparat verläßt. Auch bei der Entwässerung von Torf bietet die Anwendung des Filtersteines besondere Vorteile insofern, als die feinen gallertartigen, schlammigen Bestandteile des Torfes durch den Filterstein zurückgehalten werden und infolgedessen eine Verstopfung des Filters vermieden wird, dann aber auch die entwässerten Torfmassen infolge ihres Gehaltes an den genannten Gallertmassen insbesondere für die Verkokung bedeutend wertvoller geworden sind.But the use of the filter stones for the present purpose offers something special Advantages than complete bacterial cleaning when draining sewage sludge takes place so that the water leaves the apparatus almost free of bacteria. Also provides for the drainage of peat the use of the filter stone has particular advantages in that the fine gelatinous, muddy components of the peat are retained by the filter stone and as a result, clogging of the filter is avoided, but also the drained ones Peat masses due to their content of the gelatinous masses mentioned, in particular for coking have become significantly more valuable.
Eine Ausführung für eine derartige Entwässerungsanordnung für kontinuierlichen Betrieb ist in Fig. 1 im Schnitt dargestellt.A design for such a drainage arrangement for continuous operation is shown in Fig. 1 in section.
A bedeutet die unter Druck zu filtrierende Masse. B ist ein Gußeisenkörper zur Stützung der künstlichen Steinplatten, welche als Filtermaterial benutzt werden; S1 sind Versteifungsrippen des ,Gußeisenkörpers B. In den Steinplatten C sind Ablaufkanäle D für das filtrierte Wasser vorgesehen. Die Platten C werden vorteilhaft durch eine Druckleitung E mit Zement gefüllt, so daß sie mit dem Gußeisen einen einheitlichen Körper bilden. Es wird nun zunächst durch eine Schlammpumpe der Innenraum A gefüllt und der Abfluß durch ein Überdruckventil verhindert. Durch die Anwendung des Druckes findet eine Entwässerung bzw. Trocknung des Materials statt, so daß nach relativ kurzer Zeit die innere Reibung der zu entwässernden Schlammassen so groß ist, daß sie einen Gegendruck am Austrittsende für die Schlammassen nicht mehr benötigt. Alsdann kann kontinuierlich der zu entwässernde Schlamm in den Apparat 6g gepumpt werden, während die abgeschiedene A means the mass to be filtered under pressure. B is a cast iron body to support the artificial stone slabs, which are used as filter material; S 1 are stiffening ribs of the cast iron body B. In the stone slabs C drain channels D are provided for the filtered water. The plates C are advantageously filled with cement through a pressure line E so that they form a unitary body with the cast iron. The interior A is now first filled by a sludge pump and the drainage is prevented by a pressure relief valve. The application of pressure causes dewatering or drying of the material, so that after a relatively short time the internal friction of the sludge masses to be dewatered is so great that it no longer needs a counterpressure at the outlet end for the sludge masses. The sludge to be dewatered can then be pumped continuously into the apparatus 6g, while the separated sludge
