Damit wird minimaler Wasserverbrauch bei vorgegebener Reinigungsqualität erreicht.This enables cyclical operation, with the endless belt being acted on in strips in each detent position. This ensures minimal water consumption with a specified cleaning quality.

Description

Die Erfindung betrifft eine Reinigungsvorrichtung für ein Endlosband mit einem quer zum Endlosband axial verschiebbaren Spritzrohr mit mehreren Spritzdüsen und einer Antriebsvorrichtung für das Spritzrohr, wobei die Spritzdüsen einen vorgegebenen Abstand A und eine Spritzbreite S haben.The invention relates to a cleaning device for an endless belt with a spray tube which can be displaced axially transversely to the endless belt and has a plurality of spray nozzles and a drive device for the spray tube, the spray nozzles having a predetermined distance A and a spray width S.

Endlosbänder werden beispielsweise bei Bandfilterpressen eingesetzt, und von Zeit zu Zeit ist es erforderlich, eine Reinigung der verwendeten Siebbänder durchzuführen. Hierzu sind Spritzrohre bekannt, die senkrecht zur Bewegungsrichtung des Endlosbandes verlaufen und in denen mehrere Düsen eingebracht sind, die einen Wasserstrahl auf die Oberfläche des Endlosbandes spritzen. Dabei bewegt sich das Spritzrohr kontinuierlich um eine vorgegebene Strecke in seiner Längsachse, damit die Spritzdüsen möglichst alle Stellen des Endlosbandes erfassen.Endless belts are used for example in belt filter presses, and from time to time it is necessary to clean the sieve belts used. For this purpose, spray pipes are known which run perpendicular to the direction of movement of the endless belt and in which several nozzles are introduced which spray a water jet onto the surface of the endless belt. The spray tube moves continuously by a predetermined distance in its longitudinal axis so that the spray nozzles capture as many positions of the endless belt as possible.

Es hat sich jedoch herausgestellt, daß bei der bisher verwendeten Betriebsart, bei welcher das Spritzrohr langsam oder schnell bewegt wird, immer wieder ungereinigte Leerstellen auf dem Band verbleiben.However, it has been found that in the operating mode used hitherto, in which the spray tube is moved slowly or quickly, uncleaned empty spaces always remain on the belt.

Aufgabe der Erfindung ist es, eine derartige Reinigungsvorrichtung so zu verbessern, daß eine zuverlässigere Reinigung des Endlosbandes erzielt wird.The object of the invention is to improve such a cleaning device so that a more reliable cleaning of the endless belt is achieved.

Erfindungsgemäß wird diese Aufgabe dadurch gelöst, daß der Abstand der Spritzrohre ein Mehrfaches der Spritzbreite beträgt, und daß das Spritzrohr auf seinem Verschiebeweg n = A/S Rastpositionen aufweist, deren Abstand etwa der Spritzbreite oder einem Bruchteil davon entspricht.According to the invention, this object is achieved in that the distance between the spray pipes is a multiple of the spray width, and that the spray pipe has n = A / S locking positions on its displacement, the distance of which corresponds approximately to the spray width or a fraction thereof.

Mit einer derartigen Anordnung ermöglicht die erfindungsgemäße Lösung einen Taktbetrieb in dem Sinne, daß bei feststehendem Spritzrohr in einer seiner Rastpositionen die Spritzdüsen das Endlosband streifenweise beaufschlagen und dort eine gründliche Reinigung durchführen und danach das Spritzrohr in die nächste Rastposition verschoben wird und die Spritzdüsen dann benachbarte Streifenbahnen beaufschlagen.With such an arrangement, the solution according to the invention enables a cycle operation in the sense that when the spray tube is stationary in one of its locking positions, the spray nozzles act on the endless belt in strips and carry out thorough cleaning there and then the spray tube is moved into the next locking position and the spray nozzles then adjacent strip paths act upon.

Diese Lösung kann auf die verschiedensten Anwendungsbereiche und Reinigungungserfordemisse einfach abgestimmt werden und ermöglicht einen minimalen Wasserverbrauch bei vorgegebener Reinigungsqualität.This solution can be easily adapted to a wide range of applications and cleaning requirements and enables minimal water consumption with a given cleaning quality.

Ein Ausführungsbeispiel der Erfindung wird anhand der Schemazeichnung näher erläutert:

  • Ein Spritzrohr 10 ist an seinen beiden Enden in Lagern 11 und 12 axial verschiebbar gehalten und wird über eine Leitug 14 mit Spritzwasser versorgt. Das Spritzwasser wird über Düsen S1...S5 nach unten abgegeben und beaufschlagt dort ein Endlosband 20, das um eine Walze 21 geführt ist. Der Abstand des Spritzrohres 10 von der Oberseite des Endlosbandes 20 und der Spritzwinkel α ist derart gewählt, daß sich bei einem vorgegebenen Abstand A der Spritzdüsen S1...S5 untereinander eine Spritzbreite S ergibt, die einen Teil des Endlosbandes 20 abdeckt.
An embodiment of the invention is explained in more detail using the schematic drawing:
  • A spray tube 10 is axially displaceably held at its two ends in bearings 11 and 12 and is supplied with spray water via a conduit 14. The spray water is discharged downwards through nozzles S1 ... S5 and there acts on an endless belt 20 which is guided around a roller 21. The distance of the spray tube 10 from the top of the endless belt 20 and the spray angle α is chosen such that, given a predetermined distance A of the spray nozzles S1 ... S5, there is a spray width S which is part of the endless belt 20 covers.

Zur axialen Verschiebung des Spritzrohres 10 ist dieses in eine Antriebsvorrichtung 13 geführt, die hydraulisch, pneumatisch oder elektrisch ausgestaltet sein kann und die eine Raststellung R aufweist, die mit zwei Raststellungen R 1, R 2 auf dem Spritzrohr 10 zusammenarbeitet. Der Abstand x der beiden Raststellungen Rl, R2 ist dabei beim dargestellten Ausführungsbeispiel gleich groß gewählt wie die Spritzbreite S.For the axial displacement of the spray tube 10, it is guided into a drive device 13 which can be designed hydraulically, pneumatically or electrically and which has a locking position R which cooperates with two locking positions R 1, R 2 on the spray tube 10. The distance x between the two locking positions Rl, R2 is chosen in the illustrated embodiment to be the same size as the spray width S.

Die Reinigungsvorrichtung arbeitet wie folgt:

  • Nachdem in der dargestellten Position eine ausreichende streifenweise Beaufschlagung des Endlosbandes 20 durchgeführt worden ist, wird die Antriebsvorrichtung 13 angesteuert, und diese verschiebt das Spritzrohr 10 nach rechts, bis dessen Rastposition R1 in Eingriff mit der Rastposition R der Antriebsvorrichtung 13 kommt. In dieser Position beaufschlagen dann die fünf Spritzdüsen S1...S5 die bisher freigebliebenen Streifen des Endlosbandes 20 und reinigen diese Bereiche.
The cleaning device works as follows:
  • After a sufficient strip-wise loading of the endless belt 20 has been carried out in the position shown, the drive device 13 is actuated, and this moves the spray tube 10 to the right until its locking position R1 comes into engagement with the locking position R of the drive device 13. In this position, the five spray nozzles S1 ... S5 then act on the strips of the endless belt 20 which have been left free until now and clean these areas.

Beim dargestellten Ausführungsbeispiel sind fünf Spritzdüsen und zwei Rastpositionen dargestellt. Es versteht sich jedoch von selbst, daß die Anzahl der Spritzdüsen und die Anzahl der Rastpositionen auf die jeweiligen Erfordernisse ohne weiteres angepaßt werden kann.In the illustrated embodiment, five spray nozzles and two locking positions are shown. However, it goes without saying that the number of spray nozzles and the number of latching positions can be easily adapted to the respective requirements.
