Abstract

Short slow moving air impervious covers as fitted to vacuum drum filters to increase their effectiveness, esp. for sludge drainage in effluent purification, and tending to creep sideways are kept running true over two rollers. The roller bearings to one end of the rollers are pivoted, while at the control end they are firmly connected, so that both rollers must shift together. The tendency of the belting to wander is detected by a feeler, which actuates an electric or hydraulic motor for the automatic shifting of the rollers.

Description

Bandregelung für Vakuum-Filtermaschinen PATENTANMELDUNG In der Abwasserreinigung werden zur Entwässerung der anfallenden Schlämme Vakuum-Filtermaschinen eingesetzt. Belt control for vacuum filter machines PATENT APPLICATION In wastewater treatment vacuum filter machines are used to dewater the sludge produced.

Diese Vakuum-Filtermaschinen sind zum Teil mit luftundurohlässigen Abdeckbändern ausgestattet, um einen hohen Entwässerungsgrad zu erreichen. Diese Abdeckbänder haben das Bestreben, verursacht insbesondere durch ungleichmäßige Schlammanlagerungen auf dem Filtertuch, seitlich abzuwandern.Some of these vacuum filter machines are air-permeable Masking tapes equipped to achieve a high degree of drainage. These Masking tapes tend to be caused in particular by uneven sludge deposits on the filter cloth to wander sideways.

In vielen Fällen wird die Regelung dieser Bänder von Hand vorgenommen. Ein Fortschritt gegenüber dieser Handregelung bedeutet die automatische Bandregelung mit Regeleinrichtung.In many cases these bands are adjusted manually. The automatic belt control is a step forward compared to this manual control with control device.

Bei diesen Regeleinrichtungen wird, insbesondere bei schnell laufenden Bändern der Papierindustrie, die Bandabweichung abgetastet und entweder elektromechanisch oder elektrohydraulisch korrigiert. Die Korrektur erfolgt in der Weise, daß eine Leitwalze einseitig beweglich gelagert und auf der Regelseite in Längsbewegung des Bandes automatisch verschoben wird.With these control devices, especially with fast-running Belts of the paper industry, the belt deviation is scanned and either electromechanical or corrected electrohydraulically. The correction is made in such a way that a Guide roller mounted movably on one side and on the control side in longitudinal movement of the Is automatically moved.

Bei der Regelung längslaufender Abdeckbänder von Trommel-Filtermaschinen ist dieses Verfahren in der jetztigen Form nicht anwendbar. Bei Verstellung nur einer Walze erfolgt eine einseitige Dehnung und Deformierung des Bandes. Die Regelung des Bandes muß durch 2 Walzen erfolgen, die, gemäß Zeichnung, hintereinander liegend zusammen verstellt werden.When regulating the longitudinal cover strips of drum filter machines this procedure is not applicable in its current form. With adjustment only a roller is a one-sided stretching and deformation of the tape. The regulation of the belt must be done by 2 rollers, which, according to the drawing, lie one behind the other adjusted together.

Dadurch wird 1. eine einseitige Längung des Bandes und damit eine Verzerrung desselben vermieden.This results in 1. a one-sided elongation of the belt and thus a Distortion of the same avoided.

2. wird durch den Einsatz zweier hintereinander liegender Walzen, die jeweils paralellogrammartig von der Regeleinheit bewegt werden, eine sichere Bandführung gewährleistet und Bandabwanderung vermieden, Gegenstand der Erfindung ist eine Regelung des Bandes mittels 2 Walzen. Diese beiden walzen sind auf der ochiebeseite in Ihren Lagerungen fest verbunden und werden zwangsläufIg miteinander verstellt. Die hintere Seite dieser Walzen ist gelenkig gelagert.2. is achieved through the use of two consecutive rollers, each of which is moved by the control unit like a parallel gram, a safe one Belt guidance ensured and belt drift avoided, the subject of the invention is a regulation of the belt by means of 2 rollers. These two reels are on the The sliding side is firmly connected in your storage and are inevitably connected to each other adjusted. The rear of these rollers is articulated.

Die Verstellung kann nach seitlicher Abtastung des Bandes durch Elektromotor oder durch Hydraulikkolben in bekannter Weise erfolgen. Die Verstellung der Walzen wird dabei durch das Verbindungsgestänge (Fig.1) oder über eine gemeinsame Grundplatte betätigt.The adjustment can be made after scanning the belt sideways Electric motor or by hydraulic pistons in a known manner. The adjustment of the rollers is done by the connecting rods (Fig. 1) or via a common base plate actuated.
