Description
Hochdruck-Filter insbesondere für Farbspritzanlagen Die Erfindung betrifft ein Hochdruckfilter, insbesondere für Farbspritzanlagen. High pressure filter especially for paint spraying systems. The invention relates to a high pressure filter, especially for paint spray systems.
Bei derartigen Farbspritzanlagen wird zur Dämpfung der Druckspitzen eine besondere Vorrichtung verwendet, welche in die @aitung für die Med@umzufuhr zum Spritzwerkzoug eingesetzt wird. Dabei war man bisher gezwungen die Filterein-@ichtung und den Druckspitze@dämpfer als gesonderte Hochdruckgeräto hintereinander zu schalten. Dadurch entstand ein kosteuverursachander Aufwand, Insbosondere auch, weil die hohen Mediumdrücke besondere bauliche Maßnahmen, z.B.In such paint spraying systems, the pressure peaks are attenuated a special device used, which in the @aitung for the med @ umzufuhr is used for the Spritzwerkzoug. Up to now, one was forced to install the filter and to switch the pressure peak damper in series as a separate high-pressure device. This resulted in a costly effort, especially because of the high Medium pressures special structural measures, e.g.
bezüglich der Abdichtung, erforderlich machen.with regard to the sealing, make it necessary.
Die Aufgabe der Erfindung besteht darin, die genannten Mängel zu beheben, also ein Hochdruckfilter mit einem Gerät zur Druckspitzendämpfung so zu kombinieren, daß der bauliche Aufwend gegenüber bisher geringer ist, wobei auch bezüglich des Bedarfs an Einbauraum eine Verbesserung orzielt ist.The object of the invention is to remedy the deficiencies mentioned, So to combine a high pressure filter with a device for pressure peak damping in such a way that that the structural effort compared to so far is lower, also with regard to the The need for installation space is an improvement orzielt.
Nach der Erfindung wir die bei einem Hochdruckfiltergerät der eingangs angegebanen Art dadurch erreicht, daß in dem, die Filtereinrichtung enthaltenden, vom Druckmittel durchströmten Hochdruckraum zugleich eine Vorrichtung zur Durckspitze@dampfung vorgenehen ist, weiche aus einem die Filter einrichtung umgebenden, sich @m der Gefäßwand abstützenden, Mantel gebildet wird. der aus sin@m elastisch kompressiblen Werkstoff besteht.According to the invention, we at the beginning of a high pressure filter device indicated type achieved in that in the, the filter device containing, The high pressure chamber through which the pressure medium flows is also a device for pressure peak @ attenuation is done, soft from a device surrounding the filter, @m the Vessel wall supporting, jacket is formed. the one from sin @ m which is elastically compressible Material.
Dadurch ist das Hochdruckfilter mit den Mitteln zur Druckdämpfung in einer Weise kombiniert, bei welcher für beide Vorrichtungen nur ein einziges Hochdruckgefäß mit Anschlüssen und Dichtungen benötigt wird, wodurch eine spürbare Kostensenkung für die Herstellung und eine Verkleinerung des benötigten inbauraumes.: erreicht ist.This gives the high pressure filter the means for pressure damping combined in a manner in which only one for both devices High pressure vessel with connections and seals is needed, creating a noticeable Reduction of costs for the production and a reduction of the required installation space .: is reached.
in diesem Sinne ist nach der Erfindung der Hochdruckraum als zylindrischer Raum ausgebildet, in dessen Achse ein den Deckel und den Boden mit der Gefäßwand verspannender Bolzen verläuft, wobei in dem Hochdruckraum ein zylindrischer, den Bolzen konzentrisch umgebender Filterkörper so eingesetzt ist, daß die Flüssigkeit den Filterkerper von aussen nach innen durchströmt und aus einem durch den zentralen Bolzen begrenzten Ringraum abgeführt wird.In this sense, according to the invention, the high pressure chamber is cylindrical Space formed, in the axis of which a lid and the bottom with the vessel wall bracing bolt runs, wherein in the high pressure chamber a cylindrical, the Bolt concentrically surrounding the filter body is inserted so that the liquid flows through the filter cartridge from the outside to the inside and from one through the central one Bolt limited annulus is discharged.
Nach einem weiteren vorteilhaften Vorschlag der Erfindung ist über den zentralen Bolzen ein Stützkörper geschoben, auf welchem sich der Filtermantel abstützt und welcher mit axial durchgehenden rillenartigen Ausnehmungen für die Flüssigkeitsabführung versehen ist.According to a further advantageous proposal of the invention is over the central bolt pushed a support body on which the filter jacket rests and which with axially continuous groove-like recesses for the Liquid drainage is provided.
In der eichnung ict ein Ausführungsbeispiel der Erfindung dargestellt.In the drawing ict an embodiment of the invention is shown.
Es zeigt: Fig. 1 einen Längsschnitt durch das Gerät Fig. 2 den Schnitt ADA aus Fig. 1 In dem zylindrischen Gefäß 1 ist zwischen den beiden Flanschen 2 und 3 ein zylindrischer Ringraum 4 vorgesehen, welcher mit einem elastisch kompressiblen Werkstoff, z.B. Schaumgummi 5> ausgefüllt, ist. Win zwischen dem Deckel 6 bzw. dem Boden 7 und dem Gefäß 1 eingeklenmter biegsamer schlauch 8 trennt den Raum 9 für die chemisch aggressive Hochdruckflüssikeit von der Einlage 5. Der Deckel 6, in welchem das Anschlußsttick 12 für das Manometer 10 eingesetzt ist, und der Boden 7 sind durch einen zentralen Bolzen 11 miteinander verbinden. dieser Bolzen ist einerseits im Boden 7 und andererseits in das Anschlußstück 12 für das Manometer eingeschraubt. Das Anschlußstück ist mit einem schraubkopf 13 versehen, welcher zum Festziehen und Losen des Bolzens 11 dient.It shows: FIG. 1 a longitudinal section through the device. FIG. 2 the section ADA from FIG. 1 In the cylindrical vessel 1 is between the two Flanges 2 and 3, a cylindrical annular space 4 is provided, which with an elastic compressible material, e.g. foam rubber 5> is filled. Win between that Lid 6 or the base 7 and the vessel 1, a flexible hose 8 that is inserted into the cycle is separated the space 9 for the chemically aggressive high pressure liquid from the insert 5. The Cover 6, in which the connector 12 is inserted for the pressure gauge 10, and the bottom 7 are connected to one another by a central bolt 11. this Bolt is on the one hand in the bottom 7 and on the other hand in the connecting piece 12 for the Screwed in manometer. The connection piece is provided with a screw head 13, which is used to tighten and loosen the bolt 11.
Der Filterkörper 14 ist einerseits über einen Haltering 15 am Anschlußstück 12 und andererseits über einen Haltering 16 am Boden 7 befestigt. Über den Bolzen 11 ist ein dtützkörper 17 geschoben, dessen innere Mantelfläche am Bolzen 11 anliegt und dessen äussere Mantelfläche mit rillenförmigen axial verlaufenden Ausnehmungen 18 versehen ist, auf deren spitzen sich der Filtermantel 19 abstützt. Die Ausnehmungen 18 münden in einen Ringraum 20, welcher über einen Kanal 21 mit der Abflußbohrung 22 verbunden ist, Die Druckflüssigkeit, z.B. Farbe, wird über eine Ansohlußbohrung 23 zugeführt und. gelangt über den Kanal 24. in den Hochdruckraum 9. Dort werden die auftretenden Druckspitzen von der Einlage 5 elastisch aufgenommen und kompensiert, während das Medium von Raum 9 durch den Piltermantel 19 hin..The filter body 14 is on the one hand via a retaining ring 15 on the connection piece 12 and on the other hand attached to the floor 7 via a retaining ring 16. About the bolt 11 a support body 17 is pushed, the inner surface of which rests on the bolt 11 and its outer jacket surface with groove-shaped, axially extending recesses 18 is provided, on the tips of which the filter jacket 19 is supported. The recesses 18 open into an annular space 20, which via a channel 21 with the drain hole 22 is connected, The pressure fluid, e.g. paint, is supplied via a Ansohlußbohrung 23 supplied and. reaches the high pressure chamber via channel 24 9. There the pressure peaks that occur are elastically absorbed by the insert 5 and compensates, while the medium from space 9 through the pilter jacket 19.
