Description
Vorrichtung zur Waschung der Filterschicht bei Saugzellendreiiiiitern Das Waschen der Filterschicht bei Saugzellendrehfiltern erfolgt bisher. mittels Spritzrohre, die über der Filteroberfläche angeordnet sind und das Waschwasser aus einfachen Öffnungen entweder ausfließen lassen oder mittels Flüssigkeitsdruckes unter gleichzeitiger düsenartiger Ausbildung der Rohröffnungen auf die Filterschicht spritzen. Diese Spritzrohre haben den Nachteil, daß sie verhältnismäßig viel Waschflüssigkeit verbrauchen, trotzdem aber keine gleichmäßige Verteilung derselben über die Filterschicht be-. wirken, so daß eine völlige und restlose Auswaschung der Filterschicht nicht erzielt wird.Device for washing the filter layer in three suction cells The washing of the filter layer in suction cell rotary filters has so far been carried out. by means of Spray pipes, which are arranged above the filter surface and the washing water from simple openings either let it flow out or by means of liquid pressure with simultaneous nozzle-like formation of the pipe openings on the filter layer splash. These spray pipes have the disadvantage that they contain a relatively large amount of washing liquid consume, but still not evenly distribute the same over the filter layer loading. act so that a complete and complete washing out of the filter layer does not is achieved.
Gegenstand der Erfindung ist eine Vorrichtung zur Waschung der Filterschicht bei Saugzellendrehfiltern, welche diese Nachteile vermeidet und weiterhin den Vorteil großer Einfachheit besitzt. DieErfindung benutzt hierbei an sich bekannte Zerstäubungsvorrichtungen, die aus zwei konzentrisch ineinander angeordneten Rohren bestehen, von denen das innere zur Zufuhr der zu zerstäubenden Flüssigkeit, das äußere zur Zufuhr von Preßluft dient. Während aber bei den bekannten Vorrichtungen dieser Art der Austritt der zerstäubten Waschflüssigkeit axial am Ende der Rohre stattfindet, besteht das Neue des Erfindungsgegenstandes darin, daß beide Rohre iiber ihre Länge hin mit Öffnungen oder Düsen versehen sind, so daß die zerstäubte Flüssigkeit radial zu der Zerstäubungsvorrichtung austritt und die letztere eine Aneinanderreihung vieler Einzelzerstäuber bildet. The invention relates to a device for washing the filter layer with suction cell rotary filters, which avoids these disadvantages and continues to have the advantage possesses great simplicity. The invention uses atomization devices known per se, which consist of two concentrically arranged tubes, of which the the inner one for the supply of the liquid to be atomized, the outer one for the supply of compressed air serves. But while in the known devices of this type of the exit atomized washing liquid takes place axially at the end of the tubes, there is something new the subject of the invention is that both tubes have openings over their length or nozzles are provided so that the atomized liquid is radial to the atomizing device emerges and the latter forms a series of many individual atomizers.
Durch diese neue einfache Bauart der Zerstäubervorrichtung und durch die dabei angewandte Preßluftzerstäubung der Waschflüssigkeit, die bei Saugzellenfiltern bisher nicht verwandt wurde, wird eine sehr feine und gleichmäßige Verteilung der Waschflüssigkeit auf der Filterschicht und damit eine vollkommene und restlose Auswaschung der letzteren bei geringem Verbrauch an Waschflüssigkeit erzielt. With this new simple design of the atomizer device and through the compressed air atomization of the washing liquid that is used in the case of suction cell filters has not been used before, a very fine and even distribution of the Washing liquid on the filter layer and thus a complete and complete washing out the latter achieved with a low consumption of washing liquid.
Auf der Zeichnung ist der Erfindungsgegenstand in beispielsweiser Ausführungsform für ein Saugzellentrommeldrehfilter dargestellt. The subject of the invention is shown in the drawing by way of example Embodiment shown for a suction cell drum rotary filter.
Abb. 1 ist ein Längsschnitt durch einen Preßluftzerstäuber. Fig. 1 is a longitudinal section through a compressed air atomizer.
Abb. 2 ist ein Querschnitt dieses Zerstäuberg. Fig. 2 is a cross section of this atomizer hill.
Das Innenrohr I dient zur Zuführung der Waschflüssigkeit (Wasser) und ist mit feinen Öffnungen 2 versehen. Das Außenrohr 3 führt die Preßluft zu und besitzt ebenfalls feine düsenartige Öffnungen 4. Alle Öffnungen sind zweckmäßig gegeneinander versetzt. The inner pipe I serves to supply the washing liquid (water) and is provided with fine openings 2. The outer tube 3 supplies the compressed air and also has fine nozzle-like openings 4. All openings are suitable offset against each other.
Oberhalb der Filtertrommel 5 (Abb. 2) ist diese Zerstäubungsvorrichtung angeordnet, wobei natürlich je nach Erfordernis deren mehrere nebeneinander angeordnet sind. This atomizing device is located above the filter drum 5 (Fig. 2) arranged, with of course several arranged side by side depending on the requirements are.
