Description
Filterkörper aus mindestens zwei im Abstand voneinander spiralig gewickelten Filterstoffb ändern Die Erfindung betrifft einen Filterkörper aus mindestens zwei im Abstand voneinander spiralig gewickelten Filterstoffbändern mit zwischen diesen eingewickelten, gewellten und insbesondere streifenförmigen Abstandshaltern. Es ist bekannt, solche Abstandshalter aus gewelltem Karton herzustellen. Um biegesteif zu sein, muß der Karton jedoch solch eine Stärke haben, daß er unverhältnismäßig viel Platz beansprucht. Es sind auch Abstandshalter aus biegesteifen Metallfolien bekannt; deren Dicke hält sich zwar in brauchbaren Grenzen, sie sind aber verhältnismäßig teuer und können mit ihren harten I Kanten leicht die Filterbänder verletzen. Filter body from at least two spirally spaced apart The invention relates to a filter body made of at least two at a distance from each other spirally wound filter cloth bands with between these wrapped, corrugated and, in particular, strip-shaped spacers. It is known to manufacture such spacers from corrugated cardboard. To be rigid However, to be, the carton must be so thick that it is disproportionate takes up a lot of space. There are also spacers made of rigid metal foils known; their thickness is within usable limits, but they are proportionate expensive and can easily damage the filter belts with their hard I edges.
Diese Nachteile werden nach der Erfindung dadurch vermieden, daß die Abstandshalter aus dünnem, nicht biegesteifem Werkstoff hergestellt sind, dem besondere Mittel beigegeben sind, welche die Wellung der Abstandshalter auch nach dem Einbau aufrechterhalten. These disadvantages are avoided according to the invention in that the spacers are made of thin, non-rigid material, the special means are added, which also after the corrugation of the spacers maintained after installation.
Ein Ausführungsbeispi.el der Erfindung ist in der Zeichnung dargestellt. An Ausführungsbeispi.el the invention is shown in the drawing.
Ein gewickelter Filterkörper 1 besteht aus zwei Filterstoffbändern 2 und 3, zwischen die in der Nähe der Ränder wechselweise abdichtende Streifen 4 und 5 und Abstandshalter 6 und 7 eingewickelt sind. Die Abstandshalter sind gewellt. Erfindungsgemäß sind sie aus zwei übereinandergelegten Streifen 8 und 9 eines dünnen, aber festen Papiers hergestellt. Zwischen diesen Streifen liegen parallel zu den Streifenrändern und nicht weit von diesen entfernt zwei dünne, aber biegesteife Metalldrähte 10 und 11, insbesondere Stahldrähte. Zwischen diesen läuft ein Faden 12, zwischen jedem Draht und dem Streifenrand je ein weiterer Faden 13 und 14. Die Streifen 8 und 9 sind zusammengeklebt, wobei besonders die Fäden als Träger eines Klebstoffes benutzt werden, die in diesem Zustand zwischen die gegebenenfalls unbestrichenen Streifen einlaufen und beim darauffolgenden Durchgang zwischen Druckwalzen die Streifen miteinander fest verbinden und damit auch die Drähte in ihrer Lage festhalten. Der fertigeWickel kann mit solchen Abstandshaltern beträchtlichen Drücken widerstehen. A wound filter body 1 consists of two filter cloth bands 2 and 3, between the strips 4 which alternate sealing near the edges and 5 and spacers 6 and 7 are wrapped. The spacers are corrugated. According to the invention, they are made up of two superimposed strips 8 and 9 of a thin, but made of solid paper. Between these strips are parallel to the Strip edges and not far from these two thin but rigid Metal wires 10 and 11, in particular steel wires. A thread runs between these 12, between each wire and the edge of the strip a further thread 13 and 14. Die Strips 8 and 9 are glued together, especially the threads as a carrier Adhesive used in this state between the optionally unpainted Stripes run in and the stripes in the subsequent passage between pressure rollers Connect them firmly to one another and thus also hold the wires in their position. Of the finished wrap with such spacers can withstand considerable pressures.
Die zu filtrierende Flüssigkeit tritt an einer Stirnseite des Wickels an dem Abstandshalter 6 vorbei in den Wickel ein, durchdringt die Filterstoffbänder 2 und 3 und verläßt den Wickel an demAbstandshalter7 vorbei. Der Abstandshalter 6 ist höher gewellt und der Streifen 4 dicker als die entsprechenden Teile 7 und 5. So entsteht auf der Einströmseite ein größerer Raum als auf der Ausströmseite. The liquid to be filtered occurs at one end of the roll past the spacer 6 into the roll, penetrates the filter cloth bands 2 and 3 and leaves the roll past the spacer 7. The spacer 6 is more corrugated and the strip 4 is thicker than the corresponding parts 7 and 5. This creates a larger space on the inflow side than on the outflow side.
Diese Vergrößerung des Zulaufraumes gegenüber dem Filtratraum bei einem aus zwei im Abstand voneinander spiralig gewickelten Filterstreifen bestehen- den Filterkörper ist bereits Gegenstand eines älteren Rechtes, wobei analog den Streifen 4 und 5 Fäden verwendet sind. This enlargement of the inlet space compared to the filtrate space consisting of two filter strips wound spirally at a distance from each other the Filter body is already the subject of an older law, whereby the strip is analogous 4 and 5 threads are used.
Statt der Drähte können auch andere Mittel verwendet werden, um zu verhindern, daß die Abstandshalter flach gedrückt werden. Zum Beispiel können ihre Erhebungen an gestreckten Papierstreifen angeklebt werden. Instead of wires, other means can be used to prevent the spacers from being pressed flat. For example, theirs can Bumps are glued to stretched paper strips.
Statt des Papiers können für die Abstandshalter auch andere Werkstoffe, wie z. B. dünne Kunststofffolien, verwendet werden. Instead of paper, other materials can also be used for the spacers, such as B. thin plastic films can be used.
PATENTANSPPECCIIE 1. Filterkörper aus mindestens zwei im Abstand voneinander spiralig gewickelten Filterstoffbändern mit zwischen diesen eingewickelten, gewellten und insbesondere streifenförmigen Abstandshaltern, die aus dünnem, nicht biegesteifem Werkstoff hergestellt sind, dadurch gekennzeichnet, daß den gewellten Abstandshaltern selbst besondere Mittel beigegeben sind, welche mit dem Abstandshalter gewellt sind und die Wellung der Abstandshalter unabhängig von den Filterstoffbändern auch nach dem Einbau aufrechterhalten. PATENT APPLICATION 1. Filter body made of at least two spaced apart filter cloth tapes wound spirally from each other with wrapped between them, corrugated and in particular strip-shaped spacers made of thin, not Rigid material are made, characterized in that the corrugated Spacers themselves are given special means, which with the spacer are corrugated and the corrugation of the spacers is independent of the filter cloth bands Maintained even after installation.
