Handgerät zum Filtern von Wasser Handheld device for filtering water
BeschreibungDescription
Das Gerät filtert Roh- bzw. Brackwasser mittels handelsüblicher Filterkerzen zu entkeimtem, klarem Trinkwasser.The device filters raw or brackish water using commercially available filter candles to produce disinfected, clear drinking water.
Durch Herausziehen der abgedichteten Filterkerze aus dem Zylinderrohr wird Rohwasser durch ein Rückschlagventil (5) in den Zylinderraum eingesaugt. Anschließendes Eindrücken der Filterkerze bewirkt einen Oberdruck im Zylinder, der ein Durchströmen des Wassers durch die Filterkerze in einen beliebigen Auffangbehälter zur Folge hat.By pulling the sealed filter candle out of the cylinder tube, raw water is sucked into the cylinder chamber through a check valve (5). Subsequently pressing in the filter candle creates an overpressure in the cylinder, which causes the water to flow through the filter candle into any collecting container.
Die Verwendung der Filterkerze mit Dichtung als Kolben hat eine äußerst kompakte und leichte Bauweise zur Folge und kommt mit wenigen BauteilenThe use of the filter candle with seal as a piston results in an extremely compact and lightweight design and requires only a few components
Die Konstruktion ermöglicht den Einsatz eines Federspeichers zum selbsttätigen Filtrieren jeweils eines Hubvolumens.The design allows the use of a spring accumulator for automatic filtering of one stroke volume at a time.
Die üblichen Handfiltergeräte benutzen die Filterkerze ruhend und erzeugen den notwendigen Druck über unabhängig wirkende Pumpen.The usual hand-held filter devices use the filter candle at rest and generate the necessary pressure via independently acting pumps.
