Description
Transportables Trinkwasserfilter Die bisher im Gebrauch bekannten transportablen Filterapparate sind entweder Saug filter mit verhältnismäßig weitporigem Filterkörpern die eine unzureichende Reinigung das Wassers bewirken, oder Druckfilter mit feinporiger Filtermaterial, die aber lein sehr häufiges und auf der Reise unbequemes Auswechseln der Filterkerzen erfordern, da diese sich bei stärker verunreinigtem Wasser bald verstopfen.Portable drinking water filter Those previously known in use Portable filter devices are either suction filters with relatively wide pores Filter bodies that cause insufficient cleaning of the water, or pressure filters with fine-pored filter material, which is very common and uncomfortable when traveling Require changing the filter cartridges, as these will be more contaminated Clog water soon.
Die nachstehende Erfindung hilft diesen Mängeln dadurch ab, daß eine selbsttätige Rückspülung bei jedem neuen Benutzen des Filterapparates durch das Herausziehen des Kolbens erfolgt. Durch Vorschalten eines zweiten Filters werden ferner die groben Verunreinigungen des Wassers vom Hauptfilter ferngehalten. Eine Verschlammung des Hauptfilters wird so verhütet. The following invention remedies these shortcomings by providing a automatic backwashing with each new use of the filter device by the Pulling out the piston takes place. By connecting a second filter upstream Furthermore, the coarse impurities in the water are kept away from the main filter. One This prevents the main filter from clogging up.
In der beiliegenden Zeichnung ist ein Filterapparat gemäß der Erfindung dargestellt, und zwar in Abb. I im Querschnitt, in Abb. 2 in Aufsicht; die Abb. 3 bis 5 zeigen Einzelteile, und zwar Abb. 3 den Filterkörper, Abb. 4 und 5 das -Vorfilter. In the accompanying drawing is a filter apparatus according to the invention shown, namely in Fig. I in cross section, in Fig. 2 in plan view; the fig. 3 to 5 show individual parts, namely Fig. 3 the filter body, Fig. 4 and 5 the pre-filter.
Der Filterapparat setzt sich zusammen aus einem zylindrischen Gefäß a und einem darin wirksamen hohlen Kolben, bestehend aus dem Kolbenrohr b, an dessen oberem Ende sich der Auslauf c befindet. Mit dem Kolbennohr ist die Kolbendichtungsplatte d verbunden. Das Kolbenz, ohr ist am unteren Ende durch einen Gewindestutzen f abgeschlossen. Darüber befindet sich im Kolbenrohr ein Schlitz e, durch weibchen das Wasser nach dem Durchdringen des Filters in das Kolbenrohr eintritt. Zwischen die Dichtungsscheiben g und ii ist der Filterkörper 1 gelagert. Auf den Gewinde stutzen / wird die untere Kolbenführungsscheibei aufgeschraubt, welche durchbrochen ist und deren Durchbrechungen durch feines Drahtgewebe oder anderes geeignetes Material k verkleidet sind, ein Vorfilter bildend. The filter apparatus consists of a cylindrical vessel a and a hollow piston effective therein, consisting of the piston tube b, on its spout c is located at the top. With the piston nose is the piston sealing plate d connected. The piston ear is closed at the lower end by a threaded connector f. Above this there is a slot e in the piston tube through which the water flows enters the piston tube after penetrating the filter. Between the sealing washers g and ii, the filter body 1 is mounted. Cut / become the lower one on the thread Piston guide washer screwed on, which is perforated and its perforations are covered by fine wire mesh or other suitable material k, a Forming pre-filter.
Wird das Gefäß a mit Wasser gefüllt und der Kolben eingesetzt, so muß das Wasser zunächst durch das Vorfilter k hindurchgehen, wobei die gröbsten Verunreinigungen ausgeschieden werden. Der weitere Weg des Wassers führt durch den Filterkörper 1 und den Schlitz e, das Kolbenrohr b zum Auslauf c. If the vessel a is filled with water and the flask is inserted, so the water must first pass through the prefilter k, the coarsest Impurities are excreted. The further path of the water leads through the Filter body 1 and the slot e, the piston tube b to the outlet c.
Beim Tiefststande des Kolbens ist alles Wasser filtriert. Um das Gefäß wieder zu füllen, muß der Kolben herausgezogen werden. Hierbei bildet sich unterhalb des Kolbens im Gefäß ein Vakuum, welches das im Kolbenrohr befindliche filtrierte Wasser durch den Filterkörper in das Gefäß zurücksaugt, wobei eine Rückspülung des Filterkörpers bzmr. Reinigung der Poren des Filterkörpers von den eingedrungenen Verunreinigungen stattfindet. When the flask is at its lowest point, all the water is filtered. To that To refill the vessel, the plunger must be pulled out. This forms below the piston in the vessel a vacuum, which is located in the piston tube filtered water is sucked back through the filter body into the vessel, with a backwash of the filter body bzmr. Cleaning of the pores of the filter body from the penetrated Contamination takes place.
Aus der britischen Patentschrift 7I55 vom Jahre 1891 ist bereits ein transportables TrinExvasserfilter bekannt, das aus einem zylindrischen Hohlgefäß besteht, in welches ein mit einer Filterkerze oder Filterplatte versehener Kolben eingesetzt ist. Bei diesem bekannten Filter wird ebenfalls beim Niederdrücken des Kolbens das Wasser durch die Filterkerze oder Filterplatte filtriert, und es läuft das Filtrat durch die hohl ausgebildete Kolbenstange ab. Am Boden des zylindrischen Gefäßes ist jedoch ein Ventil vorgesehen, das sich beim Niederdrücken des Kolbens schließt, beim Hochziehen des Kolbens sich aber öffnet, wobei erneut Rohwasser in das zylindrische Gefäß eingesaugt wird. From the British patent 7I55 from 1891 is already a portable TrinExvasserfilter known, which consists of a cylindrical hollow vessel consists, in which a piston provided with a filter candle or filter plate is used. In this known filter, when the Flask filters the water through the filter candle or filter plate, and it runs the filtrate through the hollow piston rod. At the bottom of the cylindrical However, a valve is provided in the vessel, which is opened when the piston is depressed closes, but opens when the piston is pulled up, with raw water again in the cylindrical vessel is sucked in.
Die ganze Vorrichtung wirkt somit als Pumpe; eine Rückspülung des Filters im Sinne der vorliegenden Erfindung ist infolgedessen bei diesem bekannten Filter nicht möglich. The whole device thus acts as a pump; backwashing the Filters within the meaning of the present invention is consequently known in this case Filter not possible.
