Description

Anpreßvorrichtung für endlose Kuchenabnahmebänder von Filtervorrichtungen mit umlaufender Filterfläche Die Erfindung betrifft eine Anpreßvorrichtung für endlose Kuchenabnahmebänder von Filtervorrichtungen mit umlaufender Filterfläche.Pressure device for endless cake removal belts from filter devices with a circumferential filter surface The invention relates to a pressing device for endless Cake removal belts from filter devices with a circumferential filter surface.

Man liennt bereits ru Vonichtungen zur Abnahme des Kuchens von umlaufenden Filterflächen, wie Filtertrommeln und Bandfilter, bei denen ein umlaufendes Ahnahmeband sich in der Umfangsrichtung der Filterfläche ein bestimmtes Stück an diese anlegt. Diese Einrichtungen stehen im Gegensatz zu Abnahmewalzen, bei denen nur eine lineare Berührung zwischen der Abnahmewalze und der Filterfläche und damit ein verhältnismäßig hoher Anpreßdruck gegeben ist. Kuchenabnahmebänder können so angeordnet werden, daß sie ein bestimmtes Stück des Umfanges der mit Kuchen bedeckten Filterfläche übe decken. Dadurch kann der spezifische Fl chendruck niedriger gehalten werden. D endlosen Abnahmebänder haben wiederu den Nachteil, daß sich ihr Anpreßdruck a@ die ganze Kuchenoberfläche verhältnismäß@ gleichmäßig verteilt. Bei verschiedenartige Filterkuchen ist es aber notwendige den Au preßdruck der Beschaffenheit des Kucher anzupassen. One already liennt directions for the removal of the cake from circulating Filter surfaces, such as filter drums and belt filters, with a circumferential detection band A certain piece is applied to the filter surface in the circumferential direction. These devices are in contrast to take-off rollers, which only have a linear one Contact between the take-off roller and the filter surface and thus a relatively high contact pressure is given. Cake removal belts can be arranged that they have a certain piece of the circumference of the filter surface covered with cake practice cover. This allows the specific surface pressure to be kept lower. D endless take-off belts again have the disadvantage that their contact pressure a @ evenly distributed over the entire surface of the cake. With different types Filter cake it is necessary to express the nature of the cake adapt.

Man kennt an sich Anpreßvorrichtunge@ die aus mehreren umlaufenden, dicht nebel einander angeordneten endlosen Bändern b@ stehen, deren Anpreßdruck auch einzeln rege bar ist. Diese Anpreßbänder drücken ul mittelbar auf die Kuchenoberfläche. Dam soll eine gleichmäßige Anpressung des Filte kuchens auf die Trommeloberfläche zwecks besserer Entwässerung erreicht werden. One knows pressure devices @ which consist of several rotating, Endless belts b @ are densely fogged with one another, their contact pressure can also be individually regulated. These pressure belts press ul indirectly onto the cake surface. Damage should be evenly applied to the filter cake on the Drum surface can be achieved for the purpose of better drainage.

Um den Anpreßdruck des endlosen Filterkuchenabnahmebandes über die Kuchenfläche gleichmäßig oder nach Belieben zu verteilen und zu verstärken, wird vorgeschlagen, die aus mehreren umlaufenden, dicht nebeneinander allgeordneten endlosen Bänder bestehende Anpreßvorrichtung als Andrückglieder fiir die umlaufenden endlosen Kuchenabnahmebänder zu verwenden. Auf der Filter bzw. Kuchenoberfläche liegen also zunäcllst die Abnahmebänder auf und erst hinter diesen liegen dicht nebeneinander die endlosen Anpreßbänder. Durch diese Bänder hat man es in der Hand, den Anpreßdruck zu verteilen und zu regeln, und zwar auf die gesamte Breite des Abnahmebandes in verschiedener Stärke. Es besteht auch die Möglichkeit, den Anpreßdruck dieser einzelnen Bänder in an sich bekannter Weise gemeinsam oder unabhängig voneinander zu regeln. To the contact pressure of the endless filter cake removal belt over the Distribute and strengthen the cake surface evenly or at will proposed that of several encircling, closely juxtaposed general-order endless Belts existing pressing device as pressing members for the endless revolving Use cake removal tapes. So lie on the filter or cake surface First of all, the removal tapes are on and only behind these are close together the endless pressure belts. With these straps you have it in your hand, the contact pressure to be distributed and regulated across the entire width of the acceptance belt in different strength. There is also the possibility of applying pressure to this individual To regulate bands in a known manner jointly or independently.

Die Erfindung ist in einem Ausführungsbeispiel auf der Zeichnung dargestellt. und zwar zeigen: Fig. 1 einen teilweisen Schnitl. The invention is shown in one embodiment in the drawing shown. namely show: Fig. 1 a partial section.

Fig. 2 eine teilweise Vorderansicht und Fig. 3 einen Schnitt nach der Linie a-b in Fig. 1. l ist die Filtertrommel. auf der iii bekannter Weise der Filterkuchen sich ansammelt. FIG. 2 shows a partial front view and FIG. 3 shows a section the line a-b in Fig. 1. l is the filter drum. in the manner known iii Filter cake accumulates.

Zu diesem Zwecke taucht die Filtertrommel in den Rohstoffbehälter.For this purpose, the filter drum is immersed in the raw material container.

Mit der Filteroberfläche 1 arbeitet das Kuchenabnahmeband 2 zusammen, welches in bekannter Weise über Umleitwalzen 3 hinweggeführt ist und sich im Bereich der Kuchenabnahmezone am Umfang der Filtertrommel 1 anlegt. The cake removal belt 2 works together with the filter surface 1, which is guided away in a known manner over diversion rollers 3 and in the area the cake removal zone on the circumference of the filter drum 1 applies.

Gegenstand der Erfindung ist die Verwendung von Andrückgliedern in Form von dicht nebeneinander angeordneten mitumlaufenden endlosen Bändern 4 hinter dem endlosen Abnahmeband 2, wobei diese Bänder über Umleitwalzen 5 laufen, die gegebenenfalls gleichzeitig als Andrückwalzen ausgebildet sein können. Die Andrückwalzen 5, die auch in einem bestimmten Abstand von der Filtertrommel I angeordnet sein können, geben den I>reßbändern 4 eine gewisse Spannung. The invention relates to the use of pressure members in Form of closely spaced co-rotating endless belts 4 behind the endless take-off belt 2, these belts running over deflection rollers 5, which optionally can be designed as pressure rollers at the same time. The pressure rollers 5, the can also be arranged at a certain distance from the filter drum I, give the tear strips 4 a certain tension.

Diese überträgt sich auf das Abnahmeband 2, und es entsteht damit ein Andrücken des Abnahmebandes 2 auf den Filterkuchen in verstärktem Maße. Der Anpreßdruck kann den verschiedenartigen Filterkuchen angepaßt werden. This is transferred to the removal belt 2, and it is created with it Pressing the removal tape 2 onto the filter cake to a greater extent. Of the Contact pressure can be adapted to the different types of filter cake.
