Abstract

Das Auslaufteil 6 des Hydrozyklons mit zumindest in seinem Mittelteil 2 kegelstumpfförmig ausgebildetem Grundkörper schließt übergangslos in gerader Fortsetzung an das Ende mit dem kleineren Durchmesser des kegelförmigen Teils 2 an und ist zumindest in dem Bereich, wo das zentrale Leichtfraktionsabzugsrohr 5 verläuft, als gerader Zylinder ausgeführt, der das Leichtfraktionsabzugsrohr 5 konzentrisch umschließt. Vorzugsweise ist dabei der Auslaufteil 6 obenliegend angeordnet. Es kann damit eine relativ schwerere Gutstoff-Fraktion und eine relativ leichtere Leichtschmutz-Fraktion durch das zentrale Leichtstoffabzugsrohr 5 abgezogen werden. Im Einlaufbereich 3 des Hydrozyklons befindet sich zentral ein kegelförmiger Leitkörper 4, dessen Spitzenöffnungswinkel vorzugsweise zwischen 25° und 33° bemessen ist. Das gerade, zylindrische Auslaufteil 6 knickt vorzugsweise im scharfen Winkel rechtwinklig zu seinem Auslaufende 7 hin ab.The outlet part 6 of the hydrocyclone, with a base body formed in the shape of a truncated cone at least in its middle part 2, connects seamlessly in a straight continuation to the end with the smaller diameter of the conical part 2 and is designed as a straight cylinder, at least in the area where the central light fraction extraction pipe 5 runs. which concentrically surrounds the light fraction extraction pipe 5. The outlet part 6 is preferably arranged on top. A relatively heavier accept material fraction and a relatively lighter light dirt fraction can thus be drawn off through the central light material extraction pipe 5. A conical guide body 4 is located centrally in the inlet area 3 of the hydrocyclone, the tip opening angle of which is preferably between 25 ° and 33 °. The straight, cylindrical outlet part 6 preferably kinks at a sharp angle perpendicular to its outlet end 7.

Description

Die Erfindung betrifft einen Wirbelreiniger entsprechend dem Oberbegriff des Patentanspruchs 1. Ein solcher Wirbelreiniger ist bekannt aus der europäischen Patentanmeldung 0058484. Dabei ist gemäß der Variante nach Figur 1 dieser Schrift im oberen Bereich des im wesentlichen kegelförmigen Hauptkörpers ein zen­traler Leitkörper vorgesehen, der allerdings nur eine angenä­herte kegelförmige Ausbildung aufweist. An den unten angeordne­ten, den Auslauf aufweisenden kegelförmigen Teil mit dem gerin­geren Durchmesser schließt sich eine Auslaufkammer an, die einen im wesentlichen sehr viel größeren Durchmesser aufweist als das Auslaufende des kegelförmigen Teils beträgt und die von dem zentralen Abscheiderohr für die Leichtpartikel zentral durchsetzt wird. Auch die übrigen Varianten gemäß dieser Ver­öffentlichung zeigen diese Auslaufkammer.The invention relates to a vortex cleaner according to the preamble of claim 1. Such a vortex cleaner is known from European patent application 0058484. According to the variant according to FIG. 1 of this document, a central guide body is provided in the upper region of the essentially conical main body, but only one has approximately conical shape. An outlet chamber adjoins the conical part with the smaller diameter arranged at the bottom and has an essentially much larger diameter than the outlet end of the conical part and is penetrated centrally by the central separator tube for the light particles. The remaining variants according to this publication also show this discharge chamber.

Erfindungsgemäß ist erkannt worden, daß ein Weglassen dieser Auslaufkammer und eine gerade Fortsetzung des kegelförmigen Teils des Hauptkörpers in einem zylindrischen Teil, das von dem zentralen Abscheiderohr für die Leichtpartikel ein Stück durch­setzt ist und danach im wesentlichen knieförmig, vorzugsweise rechtwinklig abgeknickt ist, eine bessere Abscheidewirkung für die Leichtpartikel bewirkt.According to the invention, it has been recognized that an omission of this outlet chamber and a straight continuation of the conical part of the main body in a cylindrical part, which of the central separator pipe for the light particles is interspersed a little and then essentially knee-shaped, preferably kinked at right angles, brings about a better separation effect for the light particles.

Hierbei ist vorzugsweise vorzusehen, daß der Kegelwinkel des kegelförmigen Teils des Hauptkörpers zwischen 2° und 5°, d.h. der Kegelöffnungswinkel zwischen 4° und 10°, vorzugsweise der Kegelwinkel zwischen 2,5° und 4°, d.h. der Kegelöffnungswinkel zwischen 5° und 8° beträgt. Diese Neigungswinkel sind aber aus den bisherigen Konstruktionen der Wirbelreiniger bereits be­kannt.It should preferably be provided that the cone angle of the conical part of the main body is between 2 ° and 5 °, i.e. the cone opening angle between 4 ° and 10 °, preferably the cone angle between 2.5 ° and 4 °, i.e. the cone opening angle is between 5 ° and 8 °. However, these angles of inclination are already known from the previous designs of the vortex cleaners.

Nachfolgend wird die Erfindung anhand eines in der Zeichnung dargestellten Ausführungsbeispiels erläutert.The invention is explained below using an exemplary embodiment shown in the drawing.

Der Zyklon (Wirbelreiniger), der ja hier vorzugsweise zur Ab­scheidung von festen Verunreinigungspartikeln aus Fasersuspen­sionen dient, ist hier in der bevorzugten Einbaulage darge­stellt. Dabei befindet sich das Ende mit dem größeren Durchmes­ser, welches den Einlaufteil 3 aufweist, in der unteren Posi­tion und der Teil mit dem geringeren Durchmesser, an das sich das Auslaufteil 6 anschließt, in der oberen Lage, weil ja hier eine mit leichten Verschmutzungen angereicherte Fraktion abge­zogen werden soll, welche spezifisch leichtere Bestandteile aufweist, als das spezifische Gewicht der Suspension (Flüssig­keit) beträgt. Natürlich ist auch die umgekehrte oder eine ho­rizontale Einbaulage möglich.The cyclone (vortex cleaner), which is used here preferably for separating solid contaminant particles from fiber suspensions, is shown here in the preferred installation position. The end with the larger diameter, which has the inlet part 3, is in the lower position and the part with the smaller diameter to which the outlet part 6 is connected is in the upper position, because here a fraction enriched with light soiling is present to be subtracted, which has specifically lighter components than the specific weight of the suspension (liquid) Of course, the reverse or a horizontal installation position is also possible.

In diesem Fall ist der mittlere Teil 2 kegelförmig ausgeführt, während Einlaufende 3 und Auslaufende 6 im wesentlichen zylin­drisch ausgeführt sind. Dabei beträgt hier die Länge des zylin­drischen Einlaufteils 3 etwa das 0,6-fache des kegelförmigen Teils 2. Es ist jedoch auch ein kürzeres, zylindrisches Ein­ laufteil 3 möglich bzw. könnte die Kegelform bis in den oberen Bereich, wo sich der Leitkörper 4 befindet, durchweg vorhanden sein. In seinem Auslaufteil 6 verläuft zentral ein Abscheide­rohr 5 für die Leichtpartikel, vorzugsweise also leichte Verun­reinigungen, wie Styropor oder auch leichte klebende Verunrei­nigungen und leichter Schmutz anderer Art, auch Luft und Gase. Der Auslaufteil 6 ist dabei zunächst gerade ausgeführt, soweit ihn das zentrale Abscheiderohr 5 durchläuft und knickt dann im wesentlichen im rechten Winkel mit seinem Auslaufende 7 ab. Durch die Abzugsöffnung 8 des Auslaufteiles wird dann die spe­zifisch relativ schwerere Suspension abgezogen, die im wesent­lichen von den leichten Verunreinigungen befreit ist. Die Sus­pension wird dem Einlaufteil 3 tangential über das Einlaufrohr 1 zugeführt, wodurch es spiralig-wendelförmig den Leitkörper 4 umströmt. Dabei ist das Verhältnis zwischen dem größten Durch­messer des kegelförmigen Leitkörpers 4 und der lichten Weite des Einlaufteils 3 des Hauptkörpers zwischen D2/D1 = 0,45 und D2/D1 = 0,75, vorzugsweise zwischen D2/D1 = 0,55 und D2/D1 = 0,63.In this case, the middle part 2 is conical, while the inlet end 3 and outlet end 6 are essentially cylindrical. Here, the length of the cylindrical inlet part 3 is approximately 0.6 times the conical part 2. However, it is also a shorter, cylindrical one Running part 3 possible or the cone shape could be consistently present up to the upper area where the guide body 4 is located. A separator tube 5 for the light particles, preferably light impurities such as polystyrene or light adhesive impurities and light dirt of another kind, also air and gases, runs centrally in its outlet part 6. The outlet part 6 is initially straight as far as it passes through the central separator tube 5 and then kinks with its outlet end 7 essentially at a right angle. The specifically relatively heavier suspension, which is essentially freed from the light impurities, is then drawn off through the discharge opening 8 of the outlet part. The suspension is fed tangentially to the inlet part 3 via the inlet pipe 1, as a result of which it flows around the guide body 4 in a spiral-helical manner. The ratio between the largest diameter of the conical guide body 4 and the inside width of the inlet part 3 of the main body is between D2 / D1 = 0.45 and D2 / D1 = 0.75, preferably between D2 / D1 = 0.55 and D2 / D1 = 0.63.

Der Spitzen- oder Kegelöffnungswinkel des Leitkörpers 4 be­trägt dabei zwischen 22° und 38°, vorzugsweise zwischen 25° und 33°.The tip or cone opening angle of the guide body 4 is between 22 ° and 38 °, preferably between 25 ° and 33 °.

Das Verhältnis der Länge des geraden Teils des Auslaufteils 6 zu seinem Durchmesser beträgt zwischen L1/D3 = 4 und L1/D3 = 6, vorzugsweise zwischen L1/D3 = 4 und L1/D3 = 5. Dabei setzt sich der gerade, zylindrische Auslaufteil 6 ohne Übergänge, Kanten oder Sprünge unmittelbar als Verlängerung des kegeligen Teils 2 des Hauptkörpers fort. Es liegt dabei vorzugsweise ein Durch­messerverhältnis des zentralen Abscheiderohres 5 zur lichten Weite des geraden Auslaufteils 6 zwischen D4/D3 = 0,37 und D4/D3 = 0,43 vor. Hierbei erstreckt sich das zentrale Abschei- derohr 5 ein sehr geringes Maß in den kegligen Teil 2 des Hauptkörpers hinein, das zwischen nahezu Null und etwa 5 oder 10 mm betragen kann.The ratio of the length of the straight part of the outlet part 6 to its diameter is between L1 / D3 = 4 and L1 / D3 = 6, preferably between L1 / D3 = 4 and L1 / D3 = 5. The straight, cylindrical outlet part 6 settles without transitions, edges or jumps immediately as an extension of the conical part 2 of the main body. There is preferably a diameter ratio of the central separator tube 5 to the inside width of the straight outlet part 6 between D4 / D3 = 0.37 and D4 / D3 = 0.43. Here, the central separator tube 5 extends a very small dimension into the conical part 2 of the main body, which can be between almost zero and approximately 5 or 10 mm.

Wie bereits erwähnt, wird hier die umgekehrte wie sonst übliche Einbaulage gewählt, wie in der Zeichnung dargestellt. Es ist aber auch schon erwähnt worden, daß auch die andere Lage, näm­lich die übliche oder eine horizontale, das heißt waagerechte Einbaulage möglich ist.As already mentioned, the opposite installation position is chosen, as shown in the drawing. However, it has already been mentioned that the other position, namely the usual or a horizontal, that is to say a horizontal, installation position is also possible.
