Description

Lagerung der Abnahmewalze und des auf dieser angreifenden Abnahmemessers bei Trommelfiltern von größerer Länge Bei großen Filtern, insbesondere solchen mit größerer Längenausdehnung, zeigt sich bei der seitherigen Lagerung der Abnahmewalze sowohl wie des Abnahmemessers der Übelstand, daß die Walze nicht gleichmäßig auf die ganze Länge der Filterfläche aufdrückt und auch das Messer die Abnahmewalze demgemäß nicht gleichförmig bestreicht.Storage of the take-off roller and the take-off knife acting on it with drum filters of greater length with large filters, especially those with greater linear expansion, can be seen in the previous storage of the take-off roller as well as the drawdown knife the disadvantage that the roller is not evenly on the entire length of the filter surface and the knife presses the take-off roller accordingly not coated uniformly.

Dieser Übelstand wird dadurch hervorgerufen, daß die beiden Außenlagerstellen zu weit voneinander entfernt sind und daher eine Durchfederung der Walzenwelle eintritt. Etwa im Mittelteil der Filterfläche wird daher die Walze einen größeren Abstand von dieser erhalten, der je nach Beschaffenheit und Trockenheit des Materials noch erhöht wird.This disadvantage is caused by the fact that the two satellite camps are too far apart and therefore a deflection of the roller shaft occurs. The roller will therefore have a greater distance in the middle part of the filter surface obtained from this, depending on the nature and dryness of the material is increased.

Die Abnahme dieses durch die Walze ist daher ungleichmäßig und die Leistung des Filters wesentlich geringer. Ebenso wird das Messer infolge seiner weit auseinander liegenden Lagerung das Material von der Walze nicht voll erfassen, und die Abnahme ist nur eine teilweise.The decrease of this by the roller is therefore uneven and the Filter performance significantly lower. Likewise, the knife becomes as a result of it bearings that are far apart do not fully grasp the material from the roller, and the decrease is only partial.

Die nachstehend beschriebene Einrichtung, welche in Abb. I in einer Seitenansicht und in Abb. 2 (schematisch in verkleinertemMaßX-stabe) in einer Vorderansicht dargestellt ist hilft den genannten Übelständen ab. The device described below, which is shown in Fig. I in a Side view and in Fig. 2 (schematically on a reduced scale X-rod) in a front view is shown helps the abuses mentioned.

An der mit a bezeichneten Filtertrommel ist die an sich bekannte, in umgekehrter Richtung sich drehende Abnahmewalze b mittels des Lagers e in dem Lagerbock i und seinem Gleitrahmen d mittels Spindel und Handrad in bekannter Weise elastisch einstellbar gelagert. An den Lagern e sind gleichzeitig die Lagerarme el für das Abnahmemesser m starr befestigt und der Messerschaft 1 selbst in bekannter Weise in einem beweglichen Lager am Ende des Armes el gelagert. Diese Lageranordnung beider Teile, im besonderen derWalze, ist nun gemäß, der Erfindung nicht nur an beiden Enden der Filterfläche, sondern nochmals in der Mitte oder auch an mehr Stellen der Gesamtfläche vorgesehen (abt. 2), so daß zwei oder mehrere gänzlich von sich getrennte und gelagerte Abnahmewalzen von kleinerer Längenausdehnung vorhanden sind, welche einmal bei den Walzen idai Durchbiegen ausschließen und ein vollständig gleichmäßig bleibendes Anlaufen an die Filterfläche gewährleisten und das andere Mal bei den Messern die gleichmäßige Abnahme durch vollen Angriff auf der Walze sichern.On the filter drum marked with a is the per se known, in the reverse direction rotating take-off roller b by means of the bearing e in the Bearing block i and its sliding frame d by means of a spindle and handwheel in a known manner elastically adjustable mounted. The bearing arms are at the same time on the bearings e el for the acceptance knife m rigidly attached and the knife shaft 1 itself in known Way stored in a movable bearing at the end of the arm el. This bearing arrangement of both parts, in particular the roller, is now according to the invention not only on both ends of the filter surface, but again in the middle or in more places of the total area provided (abt. 2), so that two or more entirely by themselves there are separate and stored take-off rollers of smaller length, which once exclude the rollers from sagging and a completely uniform one Ensure permanent tarnishing of the filter surface and the other time with the The knives ensure that they are evenly removed by fully engaging the roller.

Die Abnahlhemesser stehen in bekannter Weise unter dem Einfluß von Gewichtshebeln t, n. The abutment knives are in a known manner under the influence of Weight levers t, n.

Die vorbeschriebene unterteilte Anordnung ermöglicht eine gute Vorpressung sowie eine intensive Anpressung der einzelnen selbständig angetriebenen Walzen, insbesondere bei großen Filtertrommeln, und bedingt eine höhere Leistung als die seitherige Lagerung der Walze und die gleichmäßige Abnahme des gefilterten Materials. The subdivided arrangement described above enables a good pre-compression as well as intensive pressure on the individual, independently driven rollers, especially with large filter drums, and requires a higher performance than that since then storage of the roller and the even removal of the filtered material.
