To implement the process with a washing or rinsing machine, filtering means (20), means (18) for guiding the used washing or rinsing solution from the washing or rinsing machine (10) through the filtering means (20), a reservoir (32) for storing the filtered washing or rinsing solution and means (36) for feeding the stored washing or rinsing solution to an inlet (12) of the washing or rinsing machine (10) during an ulterior washing or rinsing operation are disclosed.

Description

% Diese in den Abfluß geleiteten Laugen stellen eine erhebliche Umweltbelastung dar. Sie belasten Kläranlagen , und Gewässer. Die Wasch- und Spülmaschinen haben einen- großen Wasserbedarf. Das stellt einen nicht unerheblichen Kostenfaktor dar. Außerdem geht Energie verloren, wenn heiße Lauge in den Abfluß geleitet wird und für einen u.U. unmittelbar anschließenden Wasch- und Spülvorgang erneut kaltes Frischwasser erwärmt werden muß. % These leaches, which are discharged into the drain, represent a considerable environmental pollution. They pollute sewage treatment plants and water bodies. The washing machines and dishwashers have a large water requirement. This is a not inconsiderable cost factor. In addition, energy is lost when hot alkali is led into the drain and may be immediately after washing and rinsing cold fresh water must be heated again.
Offenbarung der ErfindungDisclosure of the invention
Der Erfindung liegt daher die Aufgabe zugrunde, ein gegenüber den üblichen Wasch- und Spülmaschinen umweltschonenderes und kostengünstigeres Verfahren zum Waschen oder Spülen von Teilen zu schaffen.The invention is therefore based on the object of creating a more environmentally friendly and cost-effective method for washing or rinsing parts than conventional washing machines and dishwashers.
Erfindungsgemäß wird diese Aufgabe dadurch gelöst, daß nach dem Wasch- oder Spülvorgang die Wasch- oder Spüllauge durch ein Filter geleitet wird, welches Fett und/oder Schmutz aus der Wasch- oder Spüllauge entfernt, und die so gefilterte Wasch- oder Spüllauge mit dem darin enthaltenden Wasch- oder Spülmittel anschließend zur Verwendung bei einem weiteren Wasch- oder Spülvorgang gespeichert wird.According to the invention, this object is achieved in that, after the washing or rinsing process, the washing or rinsing liquor is passed through a filter which removes grease and / or dirt from the washing or rinsing liquor, and the washing or rinsing liquor filtered in this way containing detergent or dishwashing liquid is then stored for use in another washing or rinsing process.
Eine Vorrichtung zur Durchführung des Verfahrens mit einer Wasch- oder Spülmaschine ist gekennzeichnet durch Filtermittel, Mittel zum Hindurchleiten der verbrauchten Wasch- oder Spüllauge aus der Wasch- oder Spülmaschine durch die Filtermittel, einen Speicher zum Speichern der gefilterten Wasch- oder Spüllauge und Mittel zum Zuführen der gespeicherten Wasch- oder Spüllauge zu einem Einlaßanschluß der asch- oder Spülmaschine bei einem anschließenden Wasch- oder Spülvorgang. Verfahren und Vorrichtung zum Reinigen von verschmutzten TeilenA device for carrying out the method with a washing machine or dishwasher is characterized by filter means, means for passing the used washing or rinsing solution out of the washing machine or dishwasher through the filter means, a memory for storing the filtered washing or rinsing solution and means for supplying the stored washing or rinsing solution to an inlet connection of the ash or dishwasher in a subsequent washing or rinsing process. Method and device for cleaning dirty parts
Technisches GebietTechnical field
Die Erfindung betrifft ein Verfahren zum Reinigen von verschmutzten Teilen mittels einer ein wasch- oder Spülmittel enthaltenden Wasch- oder Spüllauge bei erhöhter Temperatur.The invention relates to a method for cleaning dirty parts by means of a washing or rinsing solution containing a washing or rinsing agent at elevated temperature.
Die Erfindung betrifft ferner eine Vorrichtung zur Durchführung dieses Verfahrens.The invention further relates to an apparatus for performing this method.
Zugrunde liegender Stand der TechnikUnderlying state of the art
In Waschmaschinen zum Wäschewaschen wird zulaufendem Frischwasser ein Waschmittel zugesetzt. Dieses Waschmittel löst Fette und sorgt für eine bessere Benetzung des Gewebes. Durch eine mit einem solchen Waschmittel versetzte und auf erhöhte Temperatur erwärmte Waschlauge in Verbindung mit einer mechanischen Bewegung der Wäsche wird Schmutz aus der Wäsche herausgelöst. Dieser Schmutz ist dann in der Waschlauge suspendiert. Nach Beendigung des Waschvorganges wird diese verbrauchte Waschlauge in den Abfluß geleitet.In washing machines for washing laundry, a fresh detergent is added to the incoming fresh water. This detergent dissolves fats and ensures better wetting of the tissue. A wash liquor mixed with such a detergent and heated to an elevated temperature in conjunction with a mechanical movement of the laundry removes dirt from the laundry. This dirt is then suspended in the wash liquor. At the end of the washing process, this used washing liquor is led into the drain.
In ähnlicher Weise arbeiten Geschirrspüler. Auch hier wird dem zulaufenden Frischwasser ein Spülmittel zugesetzt, das fettlösend und benetzend wirkt. Die Spüllauge wird auf erhöhte Temperatur erhitzt und durch Düsen im Umlauf gegen das zu reinigende Geschirr gesprüht. Grobe feste Teile setzen sich dabei in einem Sieb ab. Die verbrauchte Spüllauge wird auch hier nach dem Spülvorgang in den Abfluß geleitet. Nach der Erfindung wird somit die verbrauchte Wasch- oder Spüllauge nicht in den Abfluß geleitet sondern gefiltert und zur Wiederverwendung gespeichert. Die Erfindung beruht auf der Erkenntnis, daß die Wasch- oder Spüllauge die durch die Wasch- oder Spülmittel erteilte Reinigungskraft auch nach dem Wasch- oder Spülvorgang behält. Sie braucht nur von den gelösten Fetten und festen Verunreinigungen befreit werden. Dann kann die Wasch- oder Spüllauge mit gleicher Wirkung erneut benutzt werden. Es ist jedenfalls möglich, mit einem Vorrat an Wasch- und Spüllauge eine Mehrzahl von Wasch- oder Spülgängen vorzunehmen. Dadurch wird Frischwasser und Wasch- oder Spülmittel gespart. Die Umweltbelastung wird erheblich vermindert. Wenn mehrere Wasch- oder Spülgänge unmittelbar nacheinander stattfinden, wie dies insbesondere bei gewerblichen Wäschereien oder in Gastwirtschaften die Regel ist, wird auch die in der verbrauchten Wasch- oder Spüllauge gespeicherte Wärme zu einem großen Teil zurückgewonnen, so daß sich eine erhebliche Energieeinsparung ergibt.Dishwashers work in a similar way. Here too, a detergent is added to the incoming fresh water, which has a fat-dissolving and wetting effect. The detergent solution is heated to an elevated temperature and sprayed against the dishes to be cleaned by nozzles in circulation. Coarse solid parts settle in a sieve. The used soapy water is also discharged into the drain after the rinsing process. According to the invention, the used washing or rinsing liquor is therefore not passed into the drain but filtered and stored for reuse. The invention is based on the knowledge that the washing or rinsing liquor retains the cleaning power imparted by the washing or rinsing agent even after the washing or rinsing process. It only needs to be freed from the dissolved fats and solid impurities. Then the washing or rinsing water can be used again with the same effect. In any case, it is possible to carry out a plurality of wash or rinse cycles with a supply of wash and rinse water. This saves fresh water and detergents or detergents. The environmental impact is significantly reduced. If several washing or rinsing cycles take place immediately after one another, as is the rule in particular in commercial laundries or in restaurants, the heat stored in the used washing or rinsing liquor is also largely recovered, so that considerable energy savings result.
Vorteilhafterweise enthalten die Filtermittel in Reihe geschaltet ein erstes Filter, welches Fett durch Adsorption bindet, und ein zweites Filter, welches in der verbrauchten Wasch- oder Spüllauge enthaltene feste Bestandteile herausfiltert.Advantageously, the filter means, connected in series, contain a first filter, which binds fat by adsorption, and a second filter, which filters out solid constituents contained in the used washing or rinsing liquor.
Kurze Beschreibung der ZeichnungBrief description of the drawing
Ein Ausführungsbeispiel der Erfindung ist nachstehend unter Bezugnahme auf die zugehörige schematische Zeichnung näher erläutert, die eine Vorrichtung zum Waschen- oder Spülen von Teilen zeigt. Bevorzugte Ausführung der ErfindungAn embodiment of the invention is explained in more detail below with reference to the associated schematic drawing, which shows a device for washing or rinsing parts. Preferred embodiment of the invention
Mit 10 ist eine Wasch- oder Spülmaschine bezeichnet, der über einen Einlaßanschluß 12 Frischwasser oder, wie noch erläutert wird, gefilterte Wasch- oder Spüllauge zugeführt wird. Über eine Zugabeeinrichtung 14 kann ein Wasch- oder Spülmittel zugegeben werden. Aus einem Auslaßanschluß 16 tritt nach Beendigung des Wasch- oder Spülganges die verbrauchte Wasch- oder Spüllauge aus. Diese enthält Schmutz in Form von festen Bestandteilen sowie Fette. Die Wasch- oder Spüllauge wird nun nicht, wie bisher üblich, in den Abfluß geleitet, sondern wird von einer Pumpe 18 durch Filtermittel 20 gedrückt. Die Filtermittel 20 enthalten in Reihe geschaltet ein erstes Filter 22, in welchem der Wasch- oder Spüllauge die Fette durch Adhäsion entzogen werden, und ein zweites Filter 24, welches Feststoffe zurückhält. Das Filter 22 hat schwammartige Kosistenz. Das darin zurückgehaltene Fett kann durch Zusammendrücken des Filters 22 mittels einer Press- Vorrichtung 26 wieder aus dem Filter herausgedrückt werden und fließt dann über einen Ablauf 28 weg.10 with a washing machine or dishwasher is referred to, the fresh water or, as will be explained, filtered washing or rinsing solution is supplied via an inlet connection 12. A washing or rinsing agent can be added via an addition device 14. The used washing or rinsing liquor emerges from an outlet connection 16 after the washing or rinsing cycle has ended. This contains dirt in the form of solid components as well as fats. The washing or rinsing liquor is now not discharged into the drain, as was previously the case, but is pressed by a pump 18 through filter medium 20. The filter means 20 contain, connected in series, a first filter 22, in which the fats are removed from the washing or rinsing liquor by adhesion, and a second filter 24, which retains solids. The filter 22 has a sponge-like consistency. The grease retained therein can be pressed out of the filter again by compressing the filter 22 by means of a pressing device 26 and then flows away via an outlet 28.
Es hat sich gezeigt, daß an einem Auslaßanschluß 30 der Filtermittel eine ziemlich saubere Flüssigkeit austritt, welche von Fetten und festen Verunreinigungen befrei-t ist und in Lösung das weiterhin aktive Wasch- oder Spülmittel enthält. Diese gefilterte Wasch- oder Spüllauge wird in einem Speicher 32 gespeichert. Zur Speicherung der Wärme, die in der gefilterten Wasch- oder Spüllauge noch enthalten ist, ist der Speicher mit einer Wärmeisolation 34 versehen. Aus dem Speicher kann die Wasch- oder Spüllauge über ein Umschaltventil 36 wieder auf den Einlaßanschluß der Wasch- oder Spülmaschine 10 geleitet werden. Das Ventil 36 kann aber den Einlaßanschluß 12 auch mit einem Frischwasseranschluß 38 verbinden. It has been found that a fairly clean liquid emerges from an outlet connection 30 of the filter medium, which is freed of greases and solid impurities and contains the active washing or rinsing agent in solution. This filtered washing or rinsing liquor is stored in a memory 32. To store the heat that is still contained in the filtered washing or rinsing liquor, the memory is provided with thermal insulation 34. From the memory, the washing or rinsing liquor can be passed back to the inlet connection of the washing machine or dishwasher 10 via a changeover valve 36. The valve 36 can also connect the inlet connection 12 to a fresh water connection 38.
