Description

Die Erfindung betrifft eine Textilreinigungsmaschine mit einer die zu reinigende Ware aufnehmenden Behandlungstrommel, die in einen Trockungsluft-Kreislauf geschaltet ist, an den ein von der Luft durchströmter Flusenfilter angeschlossen ist, dem in einer Bypass-Schaltung über eine Flusen-Absaugdüse und eine Absaugleitung ein Zyklonabscheider nachgeordnet ist, der über eine mit einem Gebläse bestückte Absaugleitung wieder an den Trocknungsluft-Kreislauf angeschlossen ist.The invention relates to a textile cleaning machine with a treatment drum receiving the goods to be cleaned, which is connected to a drying air circuit to which an air-flowed lint filter is connected, to which a cyclone separator in a bypass circuit via a lint suction nozzle and a suction line subordinate, which is connected to the drying air circuit again via a suction line equipped with a blower.

In einer Chemischreinigungsmaschine wird zur Trocknung der in der Behandlungstrommel befindlichen Ware über ein Gebläse Trocknungsluft in einem geschlossenen Kreislauf nacheinander über eine Heizung zur Erwärmung der Trocknungsluft, durch die Behandlungstrommel und über einen Kühler zur Abscheidung des Lösemittels geführt. Die mit Lösemittel beladene Trocknungsluft wird auf einem Kälteregister abgereichert und wieder der Beheizung zugeführt. Derartige Maschinen umfassen ferner üblicherweise eine Destillierblase. Hinsichtlich des allgemeinen Aufbaus sowie der Wirkungsweise dieser Maschinen wird verwiesen z. B. auf die DE-OS 32 34 105. Eine Vorrichtung zum Ausräumen und Reinigen von Destillierblasen von Textilreinigungsmaschinen ist in der DE-PS 33 38 332 beschrieben.In a dry cleaning machine, drying of the goods in the treatment drum is carried out in succession via a blower of drying air in a closed circuit via a heater for heating the drying air, through the treatment drum and via a cooler for separating off the solvent. The drying air loaded with solvent is depleted on a cold register and returned to the heating system. Such machines typically also include a still. With regard to the general structure and the mode of operation of these machines, reference is made, for. B. on DE-OS 32 34 105. A device for clearing and cleaning stills of textile cleaning machines is described in DE-PS 33 38 332.

Der eingangs beschriebene, gattungsbildende Stand der Technik ergibt sich aus einer offenkundigen Vorbenutzung. Der Zyklonabscheider muß nach einer bestimmten Betriebszeit gereinigt werden. Hierfür ist es bisher erforderlich, den Zyklonabscheider zu öffnen, um die abgeschiedenen Flusen, Schmutzpartikel und dergleichen zu entfernen. Zur Aufrechterhaltung des Betriebes kann auch ein Austausch des mit Abscheidungen angereicherten Zyklonabscheiders gegen einen gereinigten Abscheider vorgesehen werden.The generic state of the art described at the beginning results from an obvious prior use. The cyclone separator must be cleaned after a certain operating time. So far, it has been necessary to open the cyclone separator in order to remove the separated lint, dirt particles and the like. To maintain operation, an exchange of the cyclone separator enriched with separations can be provided for a cleaned separator.

Der Erfindung liegt die Aufgabe zugrunde, die eingangs beschriebene Maschine in ihrer Handhabung unter Berücksichtigung des Umweltschutzes und des Schutzes der Bedienungspersonen sicherer zu gestalten.The object of the invention is to make the machine described in the introduction more secure in its handling, taking into account environmental protection and the protection of the operators.

Diese Aufgabe wird gemäß der Erfindung dadurch gelöst, daß der Zyklonabscheider in seinem oberen Gehäusebereich einen ventilgesteuerten, an eine Lösemittelpumpe angeschlossenen Spülanschluß und an seinem Gehäuseboden einen ventilgesteuerten Schmutzablauf aufweist, der mit einer Maschinendestillierblase verbunden ist.This object is achieved according to the invention in that the cyclone separator has a valve-controlled flushing connection connected to a solvent pump in its upper housing area and a valve-controlled dirt drain on its housing base, which is connected to a machine still.

Dadurch wird erfindungsgemäß erreicht, daß auch die Säuberung bzw. Entleerung des Zyklonabscheiders in einem vollständig geschlossenen System durchgeführt werden kann. Denn erfindungsgemäß kann die Reinigung nunmehr durch zeitgesteuerte Spülungen mit Lösemittel erfolgen, das alle Ablagerungen aus dem Zyklonabscheider herausspült und unmittelbar in die Destillierblase pumpt.It is thereby achieved according to the invention that the cleaning or emptying of the cyclone separator can also be carried out in a completely closed system. Because, according to the invention, cleaning can now be carried out by time-controlled rinsing with solvent which rinses all deposits out of the cyclone separator and pumps them directly into the still.

Weitere Vorteile der Erfindung ergeben sich aus der Beschreibung eines Ausführungsbeispiels.Further advantages of the invention result from the description of an exemplary embodiment.

In der Zeichnung ist eine als Beispiel dienende Ausführungsform der Erfindung schematisch dargestellt.An exemplary embodiment of the invention is shown schematically in the drawing.

Von einer Textilreinigungsmaschine ist lediglich im Ausschnitt eine die zu reinigende Wäsche aufnehmende Behandlungstrommel 1 dargestellt, die in einen Trocknungsluft-Kreislauf 2 geschaltet ist, der unter anderem über einen Luftkühler 3 geführt ist. In den Strömungsweg der Luft ist ein Flusenfilter 4 geschaltet, der im Ausführungsbeispiel ein von einem Motor 5 angetriebener, aus Metallgaze bestehender Rotations-Flusenfilter ist, der an seinem oberen Ende eine Flusen-Absaugdüse 6 aufweist. An letztere ist über eine mit einem Absperrventil 7 bestückte Absaugleitung 8 ein Zyklonabscheider 9 angeschlossen, der mit seinem Gehäuse einen in der Rotationsachse des Gehäuses liegenden Filtereinsatz 10 umschließt. Die von dem Flusenfilter 4 kommende Absaugleitung 8 mündet oben in das Gehäuse des Zyklonabscheiders 9 und zwar in den vom Filtereinsatz 10 und dem Gehäuse gebildeten Ringraum. An das obere Ende des Filtereinsatzes 10 ist für die gereingte Luft eine Absaugleitung 11 angeschlossen, die über ein Gebläse 12 und ein nachgeschaltetes Absperrventil 13 oberhalb des Flusenfilters 4 an den Trocknungsluft-Kreislauf 2 angeschlossen ist.Of a textile cleaning machine, a treatment drum 1, which holds the laundry to be cleaned, is shown only in the detail, which is connected to a drying air circuit 2, which is guided, inter alia, via an air cooler 3. In the flow path of the air, a lint filter 4 is connected, which in the exemplary embodiment is a rotary lint filter which is driven by a motor 5 and is made of metal gauze and which has a lint suction nozzle 6 at its upper end. A cyclone separator 9 is connected to the latter via a suction line 8 equipped with a shut-off valve 7 and its housing encloses a filter insert 10 lying in the axis of rotation of the housing. The suction line 8 coming from the lint filter 4 opens at the top into the housing of the cyclone separator 9, specifically into the annular space formed by the filter insert 10 and the housing. For the cleaned air, a suction line 11 is connected to the upper end of the filter insert 10 and is connected to the drying air circuit 2 via a blower 12 and a downstream shut-off valve 13 above the lint filter 4.

Das Gehäuse des Zyklonabscheiders 9 weist in seinem oberen Bereich einen in den vorstehend genannten Ringraum mündenden Spülanschluß 14 auf, der über ein Absperrventil 15 an eine in der Zeichnung nicht näher dargestellte Lösemittelpumpe angeschlossen ist.The housing of the cyclone separator 9 has in its upper region a flushing connection 14 opening into the aforementioned annular space, which is connected via a shut-off valve 15 to a solvent pump, not shown in the drawing.

Der Gehäuseboden des Zyklonabscheiders 9 ist als ein sich nach unten verjüngender Trichter 16 ausgebildet, der über einen mit einem Absperrventil 17 bestückten Ablauf 18 mit einer nicht näher dargestellten Maschinendestillierblase verbunden ist.The bottom of the housing of the cyclone separator 9 is designed as a funnel 16 which tapers downwards and is connected to a machine still, not shown, via an outlet 18 equipped with a shut-off valve 17.

Über das Gebläse 12 werden aus der den Flusenfilter 4 durchströmenden Trocknungsluft Flusen und Schmutzpartikel über die Flusen-Absaugdüse 6 abgesaugt und in den Zyklonabscheider 9 eingespeist, wo sich Flusen 19, Schmutzpartiekel oder dergleichen im Ringraum zwischen dem Zyklonabscheidergehäuse und dem Filtereinsatz 10 absetzen und im Trichter 16 bzw. Bodenbereich sammeln. Das Gebläse 12 saugt dann die so gereinigte Luft durch den Filtereinsatz 10 hindurch und drückt sie hinter dem Absperrventil 13 in den Trocknungsluft-Kreislauf 2. In bestimmten ggf. automatisch gesteuerten Zeitintervallen wird nach Öffnung der Absperrventile 15,17 Lösemittel in den genannten Ringraum des Zyklonabscheiders 9 gepumpt. Hierdurch erfolgt eine Reinigung der Gehäuseinnenwandung des Zyklonenabscheiders 9 sowie der Außenfläche des Filtereinsatzes 10; vor allem aber werden Flusen, Schmutzpartikel und dergleichen in den Bereich des Ablaufs 18 geschwemmt und von dort in die Maschinendestillierblase gepumpt.Via the blower 12, fluff and dirt particles are sucked out of the drying air flowing through the fluff filter 4 via the fluff suction nozzle 6 and into the cyclone separator 9 fed where lint 19, dirt particles or the like settle in the annular space between the cyclone separator housing and the filter insert 10 and collect in the funnel 16 or bottom area. The blower 12 then sucks the air cleaned in this way through the filter insert 10 and presses it behind the shut-off valve 13 into the drying air circuit 2. At certain time intervals that are automatically controlled, after opening the shut-off valves 15, 17, solvent is introduced into the annular space of the cyclone separator 9 pumped. As a result, the inner wall of the cyclone separator 9 and the outer surface of the filter insert 10 are cleaned; but above all, fluff, dirt particles and the like are washed into the area of the outlet 18 and pumped from there into the machine still.

Erfindungsgemäß wurde somit ein sich im geschlossenen System selbstreinigender Flusenfilter geschaffen. Aus der Destillierblase lassen sich dann die Rückstände in ein Entsorgungsfaß abpumpen, das keinerlei manuelle bedienbare Öffnungen mehr aufzuweisen braucht.According to the invention, a lint filter which is self-cleaning in the closed system was thus created. The residues can then be pumped out of the still into a disposal barrel which no longer has to have any manual openings.
