Spaltfilter, vorzugsweise für hochviskose FlüssigkeitenGap filter, preferably for highly viscous liquids
Die Erfindung bezieht sich auf ein Spaltfilter nach dem Oberbegriff des Hauptanspruchs.The invention relates to a slot filter according to the preamble of the main claim.
Bei einem derartigen aus der DE-PS 30 46 388 bekannten Spaltfilter ist die Spaltöffnung von außen durch ein federnd gegen den Filterkörper angedrücktes Verschlußteil abspenbar. Die Schmutzabfuhrrinne wird bei geschlossener Spaltöffnung durch Rückspulen bei geöffnetem Absperrventil gesäubert Zu diesem Zweck hat die Schmutzabfuhrrinne eine Durchgangsöffnung, die mit axialem Abstand zur Schmutzauslaßöffnung angeordnet ist Derartige Spaltfilter funktionieren bei niedrigviskosen Flüssigkeiten wie beispielsweise Schmierölen oder Dieselbrennstoff für Kraftfahrzeuge zufriedenstellend. Besteht jedoch die Aufgabe darin, hochviskose Flüssigkeiten wie schwere Heizöle zu filtern, so ergeben sich Probleme, weil sich die Schmntzabfuhrrinne nicht mehr ohne weiteres freispülen läßt und schließlich mit den abgefilterten Bestandteilen verstopftIn such a gap filter known from DE-PS 30 46 388, the gap opening can be removed from the outside by a closure part pressed resiliently against the filter body. The dirt drainage channel is cleaned when the gap opening is closed by rewinding with the shut-off valve open. For this purpose, the dirt drainage channel has a through opening which is arranged at an axial distance from the dirt outlet opening. However, if the task is to filter highly viscous liquids such as heavy heating oils, problems arise because the waste discharge channel can no longer be flushed out easily and eventually clogs up with the filtered components
Der Erfindung liegt die Aufgabe zugrunde, bei der im Oberbegriff des Hauptanspruchs beschriebenen bekannten Filterausführung das sichere Abführen von in der Schmutzrinne abgelagerten Verunreinigungen zu gewährleisten.The invention has for its object to ensure the safe removal of contaminants deposited in the dirt channel in the known filter design described in the preamble of the main claim.
Die Lösung der Aufgabe ist mit den kennzeichnenden Merkmalen des Hauptanspruchs erreichtThe object is achieved with the characterizing features of the main claim
Der abgedichtet in der Schmutzabfuhrrinne geführte Kolben schiebt den dort abgelagerten Schmutz bei geöffneter Schmutzauslaßöffnung mit seiner Reinigungsbewegung sich» in die Schmutzabfuhrleitung. Irgendein Verstopfen der Schmutzabfuhrrinne durch dort abgelagerte Verunreinigungen kann nun auch bei hochviskosen Flüssigkeiten nicht mehr eintreten.The piston, which is sealed in the dirt drainage channel, pushes the dirt deposited there with its cleaning movement into the dirt drainage line when the dirt outlet opening is open. Any clogging of the dirt drainage channel due to impurities deposited there can no longer occur even with highly viscous liquids.
Die Unteransprüche beinhalten Vorschläge über einen zweckmäßigen Antrieb des Kolbens und eine mit ihm gekoppelte Steuerung für das Absperrventil sowie über die Anordnung eines Rückschlagventils in der Schmutzabfuhrleitung.The subclaims contain proposals for an expedient drive of the piston and a control for the shut-off valve coupled to it, as well as for the arrangement of a check valve in the dirt discharge line.

An inlet channel (14) for the dirty liquid opens into the jacket of the filter housing (11). while from the bottom of the filter housing (11) an outlet channel (15) for the filtrate opens.
Im Filtergehäuse (11) ist ein hohlzylindrischer Filteikörper (16) angeordnet, der aus einer auf einen Stützkörper (17) aufgebrachten, Filterspalte (19) belassenden Drahtwicklung (20) besteht. Der Filterkörper (16) ist im Filterbetrieb radial von außen nach innen durchströmt und trennt einen von ihm umschlossenen Filtratraum (21), der von dem Stützkörper (17) in eine Vielzahl von Sektoren (22) unterteilt ist, von einem ihn umgebenden Schmutzflüssigkeitsraum (23) ab.A hollow cylindrical filter body (16) is arranged in the filter housing (11) and consists of a wire winding (20) which is applied to a support body (17) and leaves filter gaps (19). The filter body (16) is flowed through radially from the outside inward during filter operation and separates a filtrate space (21) enclosed by it, which is divided into a plurality of sectors (22) by the support body (17), from a dirty liquid space (23) surrounding it ).
Mt dem Gehäusedeckel (13) sind eine Spannplatte (24) und über Spannschrauben (25,26,27) ein Spannstück (29) verdrehsicher verbunden, das mit seinem Ansatz (30) abgedichtet in eine Einpaßbohrung (31) des Auslaßkanals (15) hineinragLMt the housing cover (13) are a clamping plate (24) and a clamping piece (29) connected by means of clamping screws (25,26,27), which with its attachment (30) seals into a fitting bore (31) of the outlet channel (15)
Der Filterkörper (16) ist mit der oberen Stirnseite abgedichtet in der Spannplatte (24) und mit der unteren Stirnseite abgedichtet im Spannstück (29) drehbar gelagert Eine Antriebsachse (32), die den Gehäusedeckel (13) durchsetzt ist über eine Rutschkupplung (33) mit der Abtriebswelle (34) eines üb» Arme (36) verdrehsicher am Gehäusedeckel (13) festgelegten Getriebemotors (35) verbunden. Die Drehrichtung der Abtriebswelle (34) des Getriebemotors (35) und damit des Filterkörpers (16) entspricht dem Pfeil (37).The filter body (16) is sealed with the upper end face sealed in the clamping plate (24) and sealed with the lower end face in the clamping piece (29). A drive shaft (32) which passes through the housing cover (13) via a slip clutch (33) connected to the output shaft (34) of a geared motor (35) secured against rotation on the housing cover (13). The direction of rotation of the output shaft (34) of the geared motor (35) and thus of the filter body (16) corresponds to the arrow (37).
Eine U-förmig ausgebildete Schmutzabfuhrrinne (40) ist mit ihrem Hinterschenkel (41) als ständig am Außenumfang des Filterkörpers (16) anliegender, einen Schaber darstellender Schmutzabstreifer (42) ausgebildet Am unteren stimseitigen Ende mündet die Schmutzabfuhrrinne (40) in eine Schmutzauslaßöffnung (43), die in eine Schmutzabfuhrleitung (44) übergeht. Die Schmutzabfuhrleitung enthält ein aus einem Absperrventil (45) und einem Rückschlagventil (46) zusammengesetztes, absperrbares Durchgang-Rückschlagventil (47).A U-shaped dirt drainage channel (40) is designed with its rear leg (41) as a dirt scraper (42), which constantly rests on the outer circumference of the filter body (16) and represents a scraper ), which merges into a dirt discharge line (44). The dirt drainage line contains a lockable through-way check valve (47) composed of a shut-off valve (45) and a check valve (46).
Der Vorderschenkel (50) der Schmutzabfuhrrinne (40) bildet mit dem Filterkörper (16) eine Spaltöffnung (51), die den abgesetzten Schmutz beim Drehen des Filterkörpers (16) in Richtung des Pfeils (37) zum Schinutzabstreifer (42) hin durchläßt Die Schmutzabfuhrrinne (40) ist an zwei Blattfedern (53,54) befestigt, die sich an den Spannschrauben (26, 27) abstützen und die Schmutzabfuhrrinne (40) radial gegen den Filterkörper (16) andrücken.The front leg (50) of the dirt drainage channel (40) forms a gap opening (51) with the filter body (16) which allows the deposited dirt when the filter body (16) is rotated in the direction of the arrow (37) towards the protective scraper (42) (40) is attached to two leaf springs (53, 54), which are supported on the tensioning screws (26, 27) and press the dirt drainage channel (40) radially against the filter body (16).
