Description
In der älteren Patentanmeldung P 1285454.5-27 ist als Abnahmevorrichtung des Kuchens von dem ablaufenden Filtertuch im Bereich einer mit sinusförmigen Erhöhungen versehenen Walze vorgeschlagen, daß die sinusförmigen Erhöhungen im Tal der Sinuskurve auf dem Walzenmantel der Umlenkwalze aufliegen und sich bis zum Erreichen des oberen Scheitels der Sinuskurve vom Mantel entfernen. In the older patent application P 1285454.5-27 is used as a removal device of the cake from the draining filter cloth in the area of one with sinusoidal elevations provided roller suggested that the sinusoidal increases in the valley of the sinusoid rest on the roll shell of the deflection roll and move up to the top Remove the apex of the sinusoid from the mantle.
Der Erfindung liegt die Aufgabe zugrunde, eine übermäßige Abnutzung des Filterbandes auszuschalten. It is an object of the invention to prevent excessive wear of the filter belt.
Die Erfindung schlägt zur Lösung vor, daß die Oberfläche der sinusförmigen Erhöhungen von drehbar gelagerten Formkörpern umgeben ist. The invention proposes to solve the problem that the surface of the sinusoidal Elevations is surrounded by rotatably mounted molded bodies.
Die Erfindung ist nunmehr an Hand der Ausführungsbeispiele in den Zeichnungen erläutert. Es zeigt Ab b. 1 die Abnahmewalze im Aufriß mit zwei vollständigen Erhöhungen, A b b. 2 einen Teilausschnitt einer Erhöhung mit zwei Formkörperarten, Ab b. 3 und 4 einen Bereich einer Erhöhung mit zwei weiteren Formkörperarten, die von einem Schlauch umgeben sind, und A b b. 5 einen Bereich einer Erhöhung mit Kugeln in einem Käfig von einem Schlauch umgeben. The invention is now based on the exemplary embodiments in FIG Drawings explained. It shows Ab b. 1 the take-off roller in elevation with two complete ones Increases, A b b. 2 a partial section of an elevation with two types of moldings, From b. 3 and 4 show a region of an elevation with two further types of shaped bodies that are surrounded by a hose, and A b b. 5 an area of an elevation with balls in a cage surrounded by a tube.
Die Abnahmewalze 1 weist sinusförmige Erhöhungen 2 auf. Auf den sinusförmigen Erhöhungen 2 sind kleine Rohrstücke oder auch gelochte Perlen 3 angebracht. The take-off roller 1 has sinusoidal elevations 2. On the sinusoidal Elevations 2 are small pieces of pipe or perforated beads 3 attached.
In Ab b. 2 haben die Bohrungen 4 dieser Rohrstücke oder Perlen 3 einen größeren Durchmesser, als der Durchmesser des Rundeisens für die sinusförmigen Erhöhungen 2 vorgesehen ist. Gemäß Ab b. 3 bis 5 kann man auch an Stelle der aufgeschobenen Perlen oder kleinen Rohrstücke einen Schlauch 5 um jedes Rundeisen vorsehen und im Zwischenraum Kugeln 6,8 oder Walzen 6, gegebenenfalls die Kugeln 8 mit einem Kugelkäfig 7 anordnen. Auf diese Weise wird die Reibung des Tuches auf den Rundstäben, die die sinusförmigen Erhöhungen bilden, vermindert. In Ab b. 2 have the bores 4 of these pipe pieces or beads 3 a larger diameter than the diameter of the round bar for the sinusoidal ones Elevations 2 is provided. According to Ab b. 3 to 5 can also be used in place of the deferred Provide a tube 5 around each round bar and bead or small pieces of pipe in the gap balls 6,8 or 6 rollers, possibly the balls 8 with a Arrange ball cage 7. In this way, the Friction of the cloth on the rods, which form the sinusoidal peaks is reduced.
