Description

KAISERLICHESIMPERIAL

PATENTAMT.PATENT OFFICE.

Die im Handel befindlichen Filterapparate, bei denen das zu filtrierende Wasser durch einen porösen Filterkörper dringen muß, leiden daran, daß sich die feinen Poren des Filterkörpers durch die Unreinlichkeiten des Wassers zu früh verstopfen. Um dieses zu verhüten, ist gemäß vorliegender Erfindung ein Vorfilter in Gestalt des Einsatzzylinders T angeordnet worden, welches zwecks seinerThe filter apparatus available on the market, in which the water to be filtered has to penetrate through a porous filter body, suffer from the fact that the fine pores of the filter body clog up too early due to the impurities in the water. To prevent this, according to the present invention, a pre-filter in the form of the insert cylinder T has been arranged, which for the purpose of his

ίο Reinigung aus drei auseinandernehmbaren Teilen a, b und d besteht und dessen Hohlraum mit grobkörniger Filtermasse ausgefüllt ist. Der Einsatzzylinder T mit dem Gummiring g verwehrt dem bei E und E1 eintretenden Wasser den direkten Zutritt zum Filterkörper C und zwingt es, seinen Lauf durch das Vorfilter erst nach unten zu nehmen; auf diesem Wege wird das Wasser schon vorgereinigt. Nachdem es aits dem Vorfilter T unten ausgetreten ist, ändert es seine Richtung und steigt jetzt erst nach oben an den Filterkörper heran, den es nun durchdringt, um bei Ä als vollständig gereinigtes Wasser herauszutreten. Durch das Vorfilter und den damit erzielten Gegenstrom wird erreicht, daß das Wasser zunächst vorgereinigt wird und außerdem auch auf dem durch den Gegenstrom erzielten längeren Weg im Filterapparat mehr Gelegenheit findet, verunreinigende Bestandteile abzusetzen.ίο cleaning consists of three dismantled parts a, b and d and the cavity is filled with coarse-grained filter material. The insert cylinder T with the rubber ring g prevents the water entering at E and E 1 from direct access to the filter body C and forces it to first take its course downwards through the pre-filter; the water is pre-cleaned in this way. After it has exited the pre-filter T at the bottom, it changes its direction and only now rises up to the filter body, which it now penetrates, in order to emerge at Ä as completely purified water. The pre-filter and the countercurrent achieved with it ensure that the water is first pre-cleaned and also has more opportunity to deposit contaminating constituents on the longer path in the filter apparatus achieved by the countercurrent.
