Abstract
Description
Die Erfindung bezieht sich auf eine Vorrichtung zum Filtrieren eines Fluids, insbesondere eines verflüssigten Kunststoffes, gemäß dem Oberbegriff des Hauptanspruches.The invention relates to a Device for filtering a fluid, in particular a liquefied one Plastic, according to the preamble of Main claim.
Im nachfolgenden wird der Begriff „Siebträger" in Verbindung mit dem Begriff „Filterelemente" benutzt, wobei darauf hinzuweisen ist, daß der Begriff „Filterelement" die verschiedenartigsten Siebe, Filter und andere Rückhalteeinrichtungen für Verschmutzungen betrifft.In the following the term "portafilter" is used in connection with the term "filter elements" used, whereupon it should be noted that the Term "filter element" the most diverse Sieves, filters and other retention devices for dirt concerns.
Eine gattungsbildende Einrichtung
ist in der
Sind die Anlagen sehr klein ausgebildet, kann ein relativ schnelles Verschieben des Siebträgers erfolgen, d. h. die Schwankung im Prozeßdruck ist wirklich nur kurzzeitig. Sind die Anlagen sehr groß, wird für das Verschieben des Siebträgers lange Zeit benötigt, da ein großer Weg und hohe Gewichte zu bewältigen sind und damit wird eine relativ lange Schwankung im Prozeßdruck bedingt, der dann für die nachfolgenden Aggregate besonders nachteilig ist.Are the systems very small, can a relatively rapid displacement of the portafilter takes place, d. H. the fluctuation is in process pressure really only for a short time. The plants are very large for the Moving the portafilter long time there a big one Way and handle heavy weights are and therefore a relatively long fluctuation in the process pressure is caused, then for the subsequent aggregates is particularly disadvantageous.
Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung zum Filtrieren eines Fluids, insbesondere für kunststoffverarbeitende Anlagen zu schaffen, bei welcher auch beim Verschieben des Siebträgers zum Zwecke des Siebwechsels der Durchfluß des verflüssigten Kunststoffes vom Zufuhrkanal zum Abfuhrkanal voll aufrechterhalten wird, so daß eine Schwankung im Prozeßdruck vermieden wird.The invention has for its object a Device for filtering a fluid, in particular for plastics processing To create systems in which also when moving the portafilter to Purpose of changing the flow of the liquefied plastic from the feed channel to the discharge channel is fully maintained, so that a fluctuation in process pressure is avoided.
Diese der Erfindung zugrundeliegende Aufgabe wird durch die Lehre des Hauptanspruches gelöst.This is the basis of the invention Task is solved by teaching the main claim.
Mit anderen Worten ausgedrückt wird vorgeschlagen, daß der Austrittskanal jedes Siebraumes langgestreckt ausgebildet ist, und zwar langgestreckt in Richtung des Siebträgers bzw. der Verschieberichtung des Siebträgers gesehen, und daß auch der Abfuhrkanal siebträgerseitig, also zur Reinsiebseite des Siebes hin gerichtet, in Längsachse des Siebträgers gesehen langgestreckt ausgebildet ist und sich dann aber zu seinem freien Ende hin kreisförmig verjüngt, wobei schließlich die Anordnung so getroffen wird, daß die in dem Siebträger ausgebildeten Siebräume so nahe in Verschieberichtung des Siebträgers hintereinander liegen, daß bei Ausschieben eines Siebes aus dem Gehäuse zum Zwecke des Siebwechsels stets eine Verbindung zwischen Zufuhrkanal und Abfuhrkanal unter Zwischenschaltung eines Siebes aufrechterhalten bleibt, da der Austrittskanal des einen bzw. des anderen Siebraumes stets eine Verbindung mit dem Abfuhrkanal sicherstellt und weiterhin der Zufuhrkanal zum einen bzw. zum anderen Sieb auch hier stets eine Verbindung sicherstellt.In other words suggested that the Exit channel of each screen space is elongated, and elongated in the direction of the portafilter or the direction of displacement of the portafilter seen, and that too the discharge channel on the filter holder side, So directed towards the pure sieve side of the sieve, in the longitudinal axis seen the portafilter is elongated and then becomes free End circular tapered, being finally the arrangement is such that those formed in the portafilter Siebräume like this lie close together in the direction of displacement of the portafilter, that at Ejecting a sieve from the housing for the purpose of changing the sieve always a connection between the feed channel and the discharge channel Interposition of a sieve is maintained since the outlet channel of the one or the other screen space always a connection with the discharge channel and the supply channel on the one hand or to the other sieve also always ensures a connection here.
Gemäß einem wesentlichen Merkmal der Erfindung wird weiterhin vorgesehen, daß der Zufuhrkanal sich im Gehäuse in je zwei Zufuhrteilkanäle aufteilt, die zu den Sieben führen. Auch hier könnte der Zufuhrkanal in Längsachse des Siebträgers gesehen oval ausgebildet sein, aber aus strömungstechnischen und fertigungstechnischen Gründen ist es vorteilhaft, Zufuhrteilkanäle zu schaffen.According to an essential feature the invention further provides that the supply channel in the housing in each divides two feed subchannels, that lead to the seven. Here, too Longitudinal feed channel of the portafilter seen to be oval, but from fluidic and manufacturing establish it is advantageous to create feed subchannels.
Der Abfuhrkanal ist vorzugsweise in einem an das Gehäuse anschließbaren Anbauteil ausgearbeitet, wodurch sowohl die Bearbeitung des eigentlichen Siebträgers bei seiner Herstellung, wie auch die Ausbildung des Abfuhrkanales in Anpassung an die ovale Gestalt des Austrittskanales fertigungstechnisch erleichtert wird.The discharge channel is preferred in one to the case connectable Attachment worked out, which allows both the processing of the actual portafilter in its manufacture, as well as the formation of the discharge channel in terms of production technology in adaptation to the oval shape of the outlet channel is facilitated.
Grundsätzlich ist darauf hinzuweisen, daß es durchaus möglich ist, sowohl den Austrittskanal wie auch den Abfuhrkanal durch einzelne, reihenartig angeordnete Bohrungen auszubilden und daß es durchaus ebenfalls im Rahmen der Erfindung liegt, auch den Zufuhrkanal in einem an das Gehäuse anschließbaren Anbauteil auszuarbeiten.Basically, it should be pointed out that it is quite possible is, both the outlet channel and the discharge channel through individual, train holes arranged in rows and that it is quite is also within the scope of the invention, the feed channel in one to the case connectable Elaborate attachment.
