KLASSE 85: Wasserleitung.CLASS 85: aqueduct.
Die vorliegende Erfindung bezieht sich auf Schlammentwässerungsapparate, bei denen ein Filtrirband gegen eine rotirende Trommel geprefst wird, während der zu entwässernde Schlamm in möglichst gleichmäfsiger Vertheilung zwischen die Trommel und das Filtrirband an der Stelle, wo letzteres auf die Trommel aufläuft, eingeführt wird, und an der Stelle, wo das Filtrirband die Trommel wieder verlassen · hat, als eine verhältnifsmäfsig trockene Masse von der Trommel wieder abgenommen wird.The present invention relates to sludge dewatering apparatus in which a Filtrirband is pressed against a rotating drum while the to be dewatered Sludge distributed as evenly as possible between the drum and the filter belt is introduced at the point where the latter runs onto the drum, and at the point where the filter belt has left the drum again as a relatively dry mass is removed from the drum again.
Bei Apparaten dieser Art zeigt sich eine grofse Neigung des Filtrirgurtes, seitwärts von der Trommel herunterzulaufen, dadurch hervorgerufen, dafs gelegentlich die Schlammlage zwischen Trommelmantel und Filtrirband auf der einen Seite der Trommel dicker ist als auf der anderen. Die vorliegende Erfindung besteht nun in Einrichtungen, um dieses Seitwärtslaufen des Bandes zu verhindern.In apparatus of this type there is a great inclination of the filter belt, sideways from running down the drum, caused by the occasional layer of mud between drum jacket and filter belt is thicker on one side of the drum than on the other. The present invention now consists in means for eliminating this sideways walking to prevent the tape.
Fig. ι zeigt den Schlammentwässerer in einer seitlichen, Fig. 2 in einer vorderen Ansicht.; Der Filtrirgurt α läuft um den unteren Theil der Trommel b, welche auf der waagrechten Achse c montirt ist, und wird durch die an einem Hebel montirte und durch ein Gewicht oder durch eine Feder belastete Spann-· rolle; d gegen die Trommel geprefst. Das Band λ ist in gleichmäfsigen Entfernungen mit Querleisten a1 versehen, welche zu beiden Seiten etwas über das Band hinausragen und an denen die an den Stirnwänden bl der Trommel b angeordneten Mitnehmer b2 angreifen und das Band mit herumführen, wobei zweckmäfsig nur die Scheiben b1 fest auf der Achse c sitzen, während die Trommel b selbst lose auf letzterer angeordnet ist und nur durch die von der Schlammschicht vermittelte Reibung zwischen ihrem Mantel und dem Filtrirband mit her'umgenommen wird. Die Mitnehmer b2 können Zahnform haben und fest auf den Scheiben b1 sitzen, oder sie können, wie in der Zeichnung angedeutet, radial verschieblich angeordnet sein, wobei sie entweder durch ihr eigenes Gewicht oder durch eine Feder in ihre wirksame Stellung gebracht werden, während kurz vor dem.Ablaufen des Bandes von der Trommel eine geneigte Fläche b& (Fig. 1) so auf die an ihren inneren Enden angeordneten Rollen έ4 einwirkt, dafs die Mitnehmer b'2 nach innen geschoben werden und aufser Eingriff mit den Querleisten a1 kommen, so dafs das Band ungehindert von der Trommel ablaufen kann. Hat sich das Filtrirband schief gezogen, so dafs die Querleisten a1, wie in Fig. 2 durch Punktirung angedeutet, eine schräge Lage bekommen haben, so werden nur die zurückgebliebenen Enden der Querleisten durch die Mitnehmer der betreffenden Trommelseite in Anspruch genommen und dadurch das Band selbsttätig wieder zurechtgerückt.Fig. 1 shows the sludge dewaterer in a side view, FIG. 2 in a front view. The filter belt α runs around the lower part of the drum b, which is mounted on the horizontal axis c , and is tightened by the tensioning roller mounted on a lever and loaded by a weight or a spring; d pressed against the drum. The belt λ is provided with transverse strips a 1 at equal distances, which protrude slightly beyond the belt on both sides and on which the carriers b 2 arranged on the end walls b l of the drum b engage and guide the belt around, with only the disks expediently b 1 sit firmly on the axis c , while the drum b itself is loosely arranged on the latter and is only entrained by the friction between its jacket and the Filtrirband mediated by the sludge layer. The driver b 2 can have a tooth shape and sit firmly on the disks b 1 , or they can, as indicated in the drawing, be arranged to be radially displaceable, whereby they are brought into their operative position either by their own weight or by a spring shortly before dem.Ablaufen the tape from the drum an inclined surface b (FIG. 1) so έ on which are arranged on their inner ends rollers 4 is applied, that the carrier b '2 inwardly to be pushed and besides engagement with the transverse strips a 1 so that the tape can run off the drum unhindered. If the filter belt has been drawn at an angle so that the transverse strips a 1 , as indicated by dots in FIG automatically adjusted again.
Damit die Mitnehmer radial über das Band zu beiden Seiten desselben hinausgreifen und eine sichere Führung für dasselbe bilden können, so lange es um die Trommel läuft, ist erförderlich, dafs das Band bereits in der richtigen Lage ausläuft, und dazu sind ein Paar Führungsschienen d1 angeordnet, zwischen denen die äufseren Enden der Querleisten a1 entlang gleiten.So that the drivers reach out radially over the belt on both sides of the same and can form a safe guide for the same as long as it runs around the drum, it is necessary that the belt already runs out in the correct position, and a pair of guide rails d 1 are required for this arranged, between which the outer ends of the transverse strips slide along a 1.
Die verschieblichen Mitnehmer haben vor festen Zähnen den Vorzug, dafs sie die Ab-The displaceable drivers have the advantage over fixed teeth that they
nähme des entwässerten Schlammes mit Hülfe eines mit Querleisten i versehenen Transportbandes h (Fig. 2) gestatten. Bei der dargestellten Ausführungsform des Apparates ist der Antrieb dieses Transportbandes ein continuirlicher und wird von der Hauptantriebswelle aus mit Hülfe einer senkrechten Zwischenwelle h- durch eine Gruppe von Kegelrädern h1 vermittelt.would allow the dewatered sludge with the aid of a conveyor belt h (Fig. 2) provided with transverse strips i. In the illustrated embodiment of the apparatus, the drive of this conveyor belt is continuous and is conveyed from the main drive shaft with the aid of a vertical intermediate shaft h- through a group of bevel gears h 1.
A-Ar1Zc2Ar3A:4 ist eine durch Stifte 66 bewegte Einrichtung zum Abklopfen der an dem von der Trommel ablaufenden Filtrirgut haften gebliebenen Schlammtheile.A-Ar 1 Zc 2 Ar 3 A: 4 is a device, moved by pins 6 6 , for knocking off the sludge particles that have adhered to the filtered material running off the drum.
