Description
Vorrichtung zur Abnahme von Filterrückständen bei Trommelfiltern, bei denen sich die Rückstände auf ein über dem Filtertuch angeordnetes endloses und grobmaschiges Band absetzen.Device for removing filter residues from drum filters, in which the residues are on an endless arranged above the filter cloth and remove the wide-meshed tape.
Die Erfindung betrifft eine Vornichtung zur Abnahme von Filterrückständen bei Trommelfiltern, bei denen sich die Rückstände auf einem über dem Filtertuch angeordneten endlosen und grobmaschigen Band absetzen. The invention relates to a device for removing filter residues with drum filters where the residue is on a filter cloth the arranged endless and coarse-meshed belt.
Das Neue der Erfindung besteht danin, daß das endlose netzartige Abnahmeband derart über den Filterbelag geführt wird, daß zwischen dem Filterbelag und dem Abnahmeband ein Zwischenraum entsteht, so daß sich die Filterrückstände auf beiden Seiten des Bandes absetzen und von Idiesem weiterbefördert werden können. The novelty of the invention consists in that the endless network-like Removal tape is guided over the filter pad in such a way that between the filter pad and the removal tape creates a gap so that the filter residues set down on both sides of the belt and can be transported further by this.
Abb. I ist eine Seitenansicht der Vorrichtung. Fig. I is a side view of the device.
Abb. 2 ist ein Schnitt nach 66 der Abb. I. Fig. 2 is a section along 66 of Fig. I.
Abb. 3 ist ein Querschnitt durch den Kranz der Trommel. Fig. 3 is a cross-section through the rim of the drum.
In dem Fiftertrog 26 befindet sich eine drehende Trommel 21, auf welcher ein Filterbelag, z. B. ein Filtertuch, befestigt ist; mit der Trommel bewegt sich ein endloses Abnahmeband 22, das aus einem Drahtnetz 23 hergestellt ist und an den Seiten durch Ketten 24 in Stellung gehalten wird. - Die Ketten 24 stehen mit Zähnen 25 der Trommel in Eingriff. Die im Behälter 26 befindliche zu entwässernde Masse wird ungehindert durch das Abnahmeband 22 gesaugt, während die Flüssigkeit durch den Filterbelag der Trommel in das Innere derselben eingezogen wird. Das endlose Abnahmeband 22 kommt beim Eintauchen in die zu filtrierende Flüssigkeit mit der Trommel in Berührung, so daß sich der Filterrückstand gut in den Maschen auf beiden Seiten des Abnahmebandes festsetzen kann. A rotating drum 21 is located in the Fiftertrough 26 which a filter pad, z. B. a filter cloth is attached; moved with the drum an endless removal belt 22 made of a wire mesh 23 and is held in place by chains 24 on the sides. - The chains are 24 meshed with teeth 25 of the drum. The in the container 26 to be dewatered Mass is sucked unhindered through the removal belt 22, while the liquid is drawn through the filter lining of the drum into the interior of the same. The endless one Removal tape 22 comes when immersed into the liquid to be filtered with the drum in contact, so that the filter residue is well in the mesh can set on both sides of the removal tape.
Über der Trommel ist ein endloses Band 30 vorgesehen, das iiber Rollen 29 geführt wird, die in einem Rahmen 28 gelagert sind und teilweise unter Federdruck stehen, um das endlose Band gegen die Filterrückstände zu drücken und diese auszupressen. Dann werden dieselben mit dem Abnahmeband 22 über Rollen 33 einer Vorrichtung 34 zugeführt, in welcher die Rückstände, welche die Form eines dünnen, breiten Streifens haben, von dem Abnahmeband in trockenem Zustande entfernt werden. An endless belt 30 is provided over the drum, which over rollers 29 is performed, which are mounted in a frame 28 and partially under spring pressure stand to press the endless belt against the filter residue and squeeze it out. Then the same with the removal tape 22 over rollers 33 of a device 34 fed, in which the residues, which take the form of a thin, wide strip must be removed from the removal tape in a dry state.
Wie aus Abb. 3 ersichtlich ist, wird das Abnahmeband 23 im Abstand Z von dem Fil terbelag über die Trommel geführt, so daß sich die Rückstände auf beiden Seiten des Abnahmebandes ansetzen können und letzteres in dem Filterrückstand eingebettet, gewissermaßen einen Verstärkungsstre.fen für die Filterrückstände bildet. Im Gegensatz zu bekannten Einrichtungen dient also das Abnahmeband lediglich zur Abführung der Filterrückstände, während das Filtertuch oder der Filterbelag 12 fest auf der Trommel sitzt und nicht in Bandform mit dem Abnahmeband bewegt wird. As can be seen from Fig. 3, the removal tape 23 is spaced Z passed from the Fil terbelag over the drum, so that the residues on both sides of the removal tape and the latter in the filter residue embedded, to a certain extent a reinforcement strip for the filter residues. In contrast to known devices, the removal tape is only used for Removal of the filter residue while the filter cloth or the filter pad 12 is fixed sits on the drum and is not moved in the form of a belt with the removal belt.
