Abwasser nimmt alsdann den Weg durch das zentrale Einführungsrohr c und strömt'durch'das nach unten mündende bzw. trichterförmige Ende in den mittleren Teil des Sammelbehälters d.
Durch die schalenförmige Prellwand bzw. das trichterförmige Ende desEinführungarohres erfolgt ein Auseinanderströmen des Abwassers nach allen Richtungen nach oben hin, wie dies die Pfeile in der Zeichnung angeben. Infolge der dadurch verringerten Geschwindigkeit des Abwassers heim Austritt aus dem Einführungsrohr c finden die fett-bzw. ölhaltigen Teilchen Zeit und Gelegenheit, sich ruhig abzuscheiden und sich zu einer Schwimmschicht s zu vereinigen, die sich , t1hniihlich auf dem Wasserspiegel w ansammelt und von Zeit zu Zeit abgenommen werden muss.
Das seiner spezifisch leichteren Schwimmstoffe entledigte Abwasser nimmt nun die Richtung mit wachsender Geschwindigkeit nach unten und strömt samt den noch darin enthaltenen Sinkstossen nach dem Trichterende zu ab, um durch das in der Bodenmitte ansetzende Abflussrohr g selbsttätig abgelassen zu werden. Das selbsttätige WeiterschaSen der im Sammelbehälter d befindlichen feineren Sinkstoffe geschieht durch den während des Betriebes entstehenden Wasser- überdruck, da der Ablauf des Fettfängers tiefer als der Einlauf liegt.
Eine besondere Bedeutung kommt der zentralen Ein-und Ableitung des Abwassers zu, und zwar insofern, als einerseits, da der Abstand zwischen der Austrittsöffnung des Einführungsrohres und den Wänden des Sammelbehälters d für jede wagerechte Ebene gleich ist, allseits eine gleichmässige Abminderung der Geschwindigkeiten nach allen oberen Richtungen hin erreicht
EMI2.1
für die abfliessenden Wasserströme gleiche itrömungsverhältnisse und eine gleichmässige Ver- grössejung der Geschwindigkeiten erzielt werden. Nur bei dieser Gestaltung des Behälters d ist eine vollkommene Abscheidung und Trennung der Schwimmstoffe von den Sinkstoffen und eine völlig gleichmässige Ausnutzung aller Wasserräume gewährleistet.
Der neue Fettfänger gestattet demnach nicht nur eine ruhige und vollkommene Abscheidung der Schwimmstoffe aus den Abwässern, sondern er verhindert auch durch die sich immer wiederholende Abwasserzufuhr das Faulen des Abwassers in den Räumen a und d, so dass lästige Geruchsentwickelungen vermieden werden, insbesondere deshalb, weil der an solchen Geruchs-

sowohl in der Kammer a als auch im Sammelbehälter d findet, sondern stets mit dem entfetteten Wasser abgeschwemmt wird. Ausserdem aber liefert der Fettfänger infolge Fehlens des sonst üblichen Sinkschlammsumpfes weitaus reinere Fett- und Ölprodukte und somit wirtschaftlich höhere Werte als andere Fettfänger. bei denen ein Sinkschlammsumpf vorhanden ist.
PATENT-ANSPRÜCHE :
1. Fett- und dgl. Fänger. in dessen Fettabscheideraum das von groben Sperr-und Sink- stoss'eu befugte Abwasser durch ein senkrecht und zentral von oben nach unten gegen eine Prellwand mündendes oder unter Hinweglassung derselben von unten nach oben gerichtetes Ein- fühi ungarohr eingeleitet wird und nach allen oberen Richtungen hin mit sich vermindernder

Wastewater then takes its way through the central inlet pipe c and flows through the downwardly opening or funnel-shaped end into the middle part of the collecting container d.
Through the bowl-shaped baffle wall or the funnel-shaped end of the introduction pipe, the sewage flows apart in all directions upwards, as indicated by the arrows in the drawing. As a result of the reduced speed of the wastewater coming out of the inlet pipe c, the fat or. oily particles time and opportunity to separate calmly and to unite to form a floating layer, which collects, similar to the water level, and has to be removed from time to time.
The wastewater, which has got rid of its specifically lighter floating matter, now takes the direction downwards with increasing speed and flows off to the end of the funnel together with the sinking thrusts it still contains, in order to be automatically drained through the drainage pipe g in the middle of the bottom. The automatic transfer of the finer suspended matter in the collecting container d occurs due to the excess water pressure created during operation, since the drainage of the grease trap is lower than the inlet.
The central inlet and outlet of the wastewater is of particular importance insofar as, on the one hand, since the distance between the outlet opening of the inlet pipe and the walls of the collecting container d is the same for every horizontal level, there is a uniform reduction in the speeds on all sides reached upper directions
EMI2.1
the same flow conditions and an even increase in speed can be achieved for the outflowing water flows. Only with this design of the container d is a complete separation and separation of the floating matter from the suspended matter and a completely uniform utilization of all water spaces guaranteed.
The new grease trap therefore not only allows a calm and complete separation of floating matter from the waste water, but also prevents the waste water from fouling in rooms a and d due to the repeated supply of waste water, so that annoying odors are avoided, especially because who at such odor
EMI2.2
takes place both in the chamber a and in the collecting tank d, but is always washed away with the degreased water. In addition, however, due to the lack of the otherwise common sinking sludge sump, the grease trap delivers far cleaner fat and oil products and thus economically higher values than other grease traps. where there is a sinking sludge sump.
PATENT CLAIMS:
1. Fat and similar catchers. in whose fat separator the waste water authorized by coarse blocking and sinking impulses is introduced through an inlet pipe that opens vertically and centrally from top to bottom against a baffle wall or, omitting it, from bottom to top, and in all directions above with diminishing
