Jig 172183 KLASSE 12 d. Jig 172183 CLASS 12 d.

Die Erfindung betrifft eine Vorrichtung zum Entwässern feuchter Stoffe, bei welcher das zu entwässernde Gut in einen von sich drehenden Siebwalzen umschlossenen Raum von den Walzenenden her unter Druck eingeführt und nach der Entwässerung durch Austrittsspalten zwischen den Walzen herausbefördert wird.The invention relates to a device for dewatering moist substances, in which the material to be dewatered in a space enclosed by rotating screen rollers Introduced under pressure from the roll ends and, after dewatering, conveyed out through exit gaps between the rolls will.

Fig. ι der Zeichnung zeigt die Vorrichtung in Seitenansicht und teilweisem Schnitt und Fig. 2 dieselbe in Vorderansicht und teilweisem Schnitt.Fig. Ι of the drawing shows the device in side view and partial section and FIG. 2 the same in front view and partial section.

Die Filterkammer wird durch drei oder mehr Trommeln, deren Umfang aus fein geschlitzten Metallsieben besteht, gebildet. Die Zeichnung zeigt vier Walzen U1, a.2, a3, av The filter chamber is formed by three or more drums, the circumference of which consists of finely slotted metal sieves. The drawing shows four rollers U 1 , a. 2 , a 3 , a v

Das Paar αγ und a2 hat feste Drehachsen und ihre Umfange liegen dicht aneinander, die Walzen a3 und αά berühren einander ebenfalls, doch sind ihre Achsen in vertikaler Richtung verstellbar, so daß zwischen den vier Trommeln ein Raum mit zwei verstellbaren Spalten für den Austritt der entwässerten Stoffe gebildet ist. ,The pair α γ and a 2 have fixed axes of rotation and their circumferences are close to each other, the rollers a 3 and α ά also touch each other, but their axes are adjustable in the vertical direction, so that between the four drums a space with two adjustable gaps for the outlet of the dehydrated substances is formed. ,

Vier ineinander greifende Stirnräder verbinden die Trommeln untereinander, von denen die Walze a.2 durch das Rad c angetrieben wird und so die anderen ebenfalls in Bewegung setzt.Four intermeshing spur gears connect the drums to one another, of which the roller a. 2 is driven by wheel c and thus also sets the others in motion.

Die beiden Kopfenden der Filterkammer sind durch den Kreuzteil d des Gestelles der Maschine geschlossen und durch ihre abgedrehten Flächen abgedichtet.The two head ends of the filter chamber are closed by the cross part d of the frame of the machine and sealed by their turned surfaces.

In der Mitte eines jeden der beiden Kreuzteile mündet je ein eine Transportschneckee mit rechts- und linksgängigen' Schneckenflügeln einschließendes Rohr. Beide Rohre münden mittels der Verbindungsrohrstücke g in ein zweites, ebenfalls mit einer Transportschnecke/ ausgerüstetes Zuführungsrohr mit Einwurftrichter. In the middle of each of the two cross parts opens a tube enclosing a transport screw with right and left-hand screw blades. By means of the connecting pipe pieces g, both pipes open into a second feed pipe with a feed funnel, which is also equipped with a screw conveyor.

Der Vorgang der Entwässerung ist folgender: The process of drainage is as follows:

Die zu entwässernden Stoffe werden ununterbrochen in den Trichter des oberen Zuführungsrohr eingeworfen, durch die erste Schnecke/ zur Hälfte nach rechts und nach links fortbewegt Und gelangen durch die zweite Schnecke e in die durch Trommeln gebildete Filterkammer.The substances to be dewatered are thrown continuously into the funnel of the upper feed pipe, moved by the first screw / half to the right and to the left and pass through the second screw e into the filter chamber formed by drums.

Durch entsprechende Drehungsgeschwindigkeit der beiden Schnecken wird der Druck und das Zusammenpressen der Stoffe schon oberhalb der Filterkammer erreicht und durch Engstellen der Trommelspalten der gewünschte Druck in der Filterkammer hergestellt, so daß das Wasser, welches aus den Stoffen entfernt werden soll, keinen anderen Weg findet als den durch die feinen Sieböffnungen der vier Trommeln. Im Innern jeder Trommel können Kammern und Kanäle (in Fig. 1 bei den Trommeln ax und a.2 dargestellt) vorgesehen werden, die bei kontinuierlicher Drehung unter Vakuum gesetzt werden können und in die das Wasser durch die hohlen Wellen h abgesaugt wird.The pressure and compression of the substances above the filter chamber is achieved by the corresponding speed of rotation of the two screws and the desired pressure is established in the filter chamber by narrowing the drum gaps so that the water that is to be removed from the substances finds no other way than through the fine sieve openings of the four drums. Inside each drum chambers and channels (shown in Fig. 1 for drums a x and a. 2 ) can be provided, which can be placed under vacuum with continuous rotation and into which the water is sucked off through the hollow shafts h.

Die hohlen Wellen sind mit einem Hauptrohr i verbunden, welches in die Saugpumpe mündet.The hollow shafts are connected to a main pipe i which opens into the suction pump.

Die auf den Walzen zurückbleibenden entwässerten Stoffe werden, nachdem sie zutage getreten sind, durch Schaber oder durch die Bürstenzylinder k abgestrichen, dabei werden zugleich die Sieböffnungen der Trommeln gereinigt.The dewatered substances remaining on the rollers are scraped off by scrapers or the brush cylinders k after they have emerged, while the screen openings of the drums are cleaned at the same time.

ίο In dieser Anordnung dient der Apparat zur Entwässerung von porösen, körnigen Stoffen, z. B. Rübenschnitzel der Zuckerfabriken. Sollen dagegen schlammige Stoffe entwässert werden, so können die Siebtrommeln mit Filtertuch bekleidet werden; bei schleimigen Stoffen, die eine ständige Waschung der Filtertücher nötig machen, wird für jede Filtertrommel ein endloses Filtertuchband aufgelegt und beliebig lang aus dem Apparat geführt, so daß eine mechanische Waschung auf dem Rückgang zur Trommel stattfinden kann.ίο In this arrangement the apparatus is used for draining porous, granular Substances, e.g. B. Beet pulp from sugar factories. Should on the other hand muddy fabrics are drained, the sieve drums can be covered with filter cloth; with slimy substances that are a constant Make it necessary to wash the filter cloths, becomes an endless one for each filter drum Filter cloth tape put on and out of the apparatus as long as desired, so that a mechanical Washing can take place on the return to the drum.

Diese endlosen Filtertuchbänder sind . in Fig. ι durch punktierte Linien / angedeutet.These endless belts of filter cloth are. in Fig. ι indicated by dotted lines /.
