Abstract

The novel separator for settling and/or floating materials, such as for example starch or fats, has to be refilled with fresh water after disposal of the separator contents. To avoid back-contamination from the separator, the fresh-water inlet possesses a free-fall section with a collecting funnel. This funnel, which is not filled during the operation of the separator, constitutes a source of odour. According to the invention, the fresh-water inlet is therefore equipped with a winding odour seal which always remains filled with water and preferably has the shape of a double U or a circular pipe and exhibits a large intake capacity upon admission of fresh water. <IMAGE>

Description

Die Neuerung bezieht sich auf einen Abscheider für Sink- und/oder Schwimmstoffe, insbesondere jedoch auf einen Stärke- oder Fettabscheider, wie er in Großküchen und Lebensmittel verarbeitenden Betrieben zum Abscheiden von Fett und Stärke eingesetzt werden muß.The innovation relates to a separator for sinking and / or floating materials, in particular, however, to a starch or fat separator, as it must be used in commercial kitchens and food processing plants to separate fat and starch.

Derartige Abscheider, die als im wesentlichen horizontal durchströmtes Beruhigungsbecken ausgebildet sind, besitzen zum Wiederbefüllen nach dem Entsorgen des Abscheiderinhalts einen Frischwasser-Rohranschluß, meist im Bereich der Auslauftauchwand. Um eine Rückverseuchung vom Abscheider aus zu vermeiden, ist vorgeschrieben, in den Frischwasser-Zulauf eine Freifallstrecke einzubauen. Der Rohranschluß endet dann außen offen in Form eines Trichters, der das Füllwasser auffängt. Das Abscheiderinnere hat dann aber neben der vorgeschriebenen Entlüftung über Dach einen offenen Ausgang, durch den üble Gerüche austreten können. Die Aufgabe, diesen Nachteil zu beseitigen wird gemäß der Neuerung dadurch gelöst, daß der Frischwasseranschluß nach der Freifallstrecke und dem Auffangtrichter einen Geruchverschluß aufweist. Als Geruchverschluß eignet sich besonders ein vertikal gewundenes Kreisrohr, das bis zum oberen Scheitel gefüllt bleibt, oder ein Doppel-U-Rohr. Diese Rohre haben die Eigenschaft, auf das zulaufende Wasser eine Heberwirkung auszuüben, so daß die Schluckmenge vergrößert und die Füllzeit entsprechend verringert wird. Wegen der hohen Strömungsgeschwindigkeit des Füllwassers kann sogar ein Spüleffekt erzielt werden, indem der Frischwasserstrahl gezielt auf die auslaufseitige Behälterwand und die Auslauftauchwand gerichtet wird. Hierzu ist eine Leiteinrichtung vorteilhaft, die als offene Rinne mit verjüngten Rinnenzweigen ausgebildet ist.Such separators, which are designed as a settling basin with essentially horizontal flow, have a fresh water pipe connection for refilling after the contents of the separator have been disposed of, usually in the area of the discharge immersion wall. In order to avoid back-contamination from the separator, it is mandatory to install a free-fall section in the fresh water inlet. The pipe connection then ends open on the outside in the form of a funnel that collects the fill water. The inside of the separator has but then in addition to the prescribed ventilation via the roof, an open exit through which bad smells can escape. The task of eliminating this disadvantage is solved according to the innovation in that the fresh water connection has an odor trap after the free fall section and the collecting funnel. A vertically wound circular pipe, which remains filled up to the top part, or a double U pipe is particularly suitable as an odor trap. These pipes have the property of exerting a lifting effect on the incoming water, so that the amount of swallowing is increased and the filling time is reduced accordingly. Because of the high flow rate of the fill water, a rinsing effect can even be achieved by directing the fresh water jet onto the outlet-side container wall and the outlet diving wall. For this purpose, a guide device is advantageous, which is designed as an open channel with tapered channel branches.

In den Zeichnungen sind bevorzugte Ausführungen der Neuerung dargestellt. Bei der Bauart nach Fig. 1 mündet der Füllanschluß 1 in der Nähe der Auslauftauchwand 2. Er ist als in den Deckel 3 einsetzbare Baueinheit mit Fußplatte 4 ausgebildet. Der mit einem Schließventil 5 versehene Zuflußstutzen 6 wird durch eine auf der Fußplatte befestigte Strebe 7 im richtigen Freifall-Abstand 6' über dem Auffangtrichter 8 gehalten. An das nachfolgende Handsperrventil 9 schließt sich innerhalb des Gehäuses 10 der kreisrohrförmige Geruchverschluß 11 an, dessen Auslauf vertikal nach unten gerichtet ist.Preferred designs of the innovation are shown in the drawings. In the design according to FIG. 1, the filling connection 1 opens in the vicinity of the outlet diving wall 2. It is designed as a unit with a base plate 4 that can be inserted into the cover 3. The inflow nozzle 6 provided with a closing valve 5 is held above the collecting funnel 8 by a strut 7 fastened to the base plate at the correct free-fall distance 6 '. The circular manual odor trap 11, whose outlet is directed vertically downward, connects to the subsequent manual shut-off valve 9 within the housing 10.

Bei der Bauform nach Fig. 2/3 mündet der Zulaustutzen 12 viertelbogenförmig von der Seite in die auslaufseitige Wand 13 des Abscheidergehäuses. Dieser Bogen ist schon Teil des sich innen fortsetzenden Doppel-U-Bogens 14, der noch über dem Klarwasserauslaufschacht 15 endet. Wie aus Fig. 3 (Draufsicht in Fig. 2) zu ersehen ist, schließt sich an den Auslauf des Geruchverschlusses 14 eine Verteilrinne 16 an, die zwei in die Gehäuseecken gerichtete Rinnenzweige 17, 19 und einen gegen die Auslauf-Tauchwand 2 zielenden Abzweig 18 enthält. Die richtige Aufteilung des Spülstrahls wird durch eine entsprechende Neigung der Rinnenabschnitte erreicht.In the design according to FIG. 2/3, the inlet connection 12 opens out in a quarter-arc shape from the side into the outlet-side wall 13 of the separator housing. This bow is already part of itself inside continued double U-bend 14, which still ends above the clear water outlet shaft 15. As can be seen from FIG. 3 (top view in FIG. 2), the outlet of the odor trap 14 is followed by a distribution channel 16 which has two channel branches 17, 19 directed into the corners of the housing and a branch 18 directed towards the discharge baffle 2 contains. The correct division of the flushing jet is achieved by an appropriate inclination of the channel sections.

Die Ausrichtung des Spülstrahls in die auslaufseitigen Ecken des Gehäuses hat den Vorteil, daß das Spülwasser auch den ganzen geneigten Boden des Abscheiders erfaßt und diesen von Sinkstoffen freispült.The alignment of the flushing jet in the outlet-side corners of the housing has the advantage that the flushing water also covers the entire inclined bottom of the separator and flushes it out of suspended matter.
