Description

Schleudermaschine mit Spaltsiebtrommel und Austragschnecke Bei den bekannten Fliehkraftschleudertrommeln, die zur Entwässerung des Gutes aus einzelnen in Achsrichtung verlaufenden Stäben gebildet sind und zwischen sich für den Austritt des Wassers durchgehende Spalten aufweisen, sind die Stabinnenflächen glatt (eben) ausgebildet. Bei diesen Einrichtungen besteht der Nachteil, daß das Gut, je nach seiner Beschaffenheit, mehr oder weniger durch die Schnecke im Umfangssinne mitgenommen wird und daß ferner die Entwässerungswirkung durch die innen glatten Roststäbe, die die Ansammlung des Wassers begünstigen, hintangehalten wird. Es ist dies darauf zurückzuführen, daß die in geringen Abständen aneinandergereihten Spaltroststäbe mit den glatten Innenflächen praktisch innen glatte Trommeln bilden.Centrifugal machine with wedge wire drum and discharge screw For the known centrifugal drums, which are used to dewater the material from each axially extending rods are formed and between them for the exit of the water have continuous crevices, the inner surfaces of the rods are smooth (even) educated. In these facilities there is the disadvantage that the good, depending on its nature, more or less carried along by the snail in the circumferential sense and that furthermore the drainage effect through the grate bars, which are smooth on the inside, that promote the accumulation of water, is prevented. It's this on due to the fact that the slotted grating bars lined up at short intervals with the smooth inner surfaces practically form smooth drums on the inside.

Gemäß der Erfindung wird dieser Nachteil dadurch vermieden, daß bei einer solchen Schleudertrommel mit in der Achsrichtung verlaufenden Spaltroststäben die Innenflächen dieser Stäbe eine dachförmige Erhöhung über den die Durchtrittsspalten bildenden unten erhalten, wie dies bereits bei Siebstäben für andere Zwecke bekannt ist. Auf diese Weise wird praktisch eine innen rauhe (gerippte) Schleudertrommel gebildet, die dem eintretenden Gut eine Führung in der Achsrichtung gibt und seine Mitnahme im tangentialen Sinne verhütet und ferner die Ansammlung des Wassers verhindert und somit die Entwässerungswirkung des Gutes vervollkommnet.According to the invention, this disadvantage is avoided in that at such a centrifugal drum with slotted grate bars running in the axial direction the inner surfaces of these rods have a roof-shaped elevation over which the passage gaps obtained below, as is already known for sieve bars for other purposes is. This practically results in a centrifugal drum that is rough inside (ribbed) formed, which gives the incoming goods a guide in the axial direction and his Prevents entrainment in the tangential sense and also prevents the accumulation of water and thus perfect the drainage effect of the property.

Auf der Zeichnung ist ein Ausführungsbeispiel des Erfindungsgegenstandes in den Abb. i, 2 und 3 in Teilansicht, Quer- und Längsschnitt wiedergegeben.The drawing shows an embodiment of the subject matter of the invention in Figs. i, 2 and 3 shown in partial view, cross section and longitudinal section.

Die Schleudertrommel i g, in der sich unabhängig von ihr eine Förderschnecke mit den Gängen To dreht, setzt sich aus parallel nebeneinander in der Achsrichtung verlaufenden Roststäben 30 zusammen, die zwischen sich nach außen sich erweiternde Spalte 3 t aufweisen. Um die erwähnte ordnungsmäßige Führung des Schleudergutes und seine gute Entwässerung zu ermöglichen, erhalten die einzelnen Stäbe 30 einen derartigen Querschnitt, daß ihre Innenflächen dachförmige .`-Aufsätze 32 bilden.The centrifugal drum ig, in which a screw conveyor with the gears To rotates independently of it, is composed of grate bars 30 running parallel to one another in the axial direction, which have gaps 3 t widening outwards between them. In order to enable the aforementioned proper guidance of the material to be centrifuged and its good drainage, the individual rods 30 are given a cross-section such that their inner surfaces form roof-shaped attachments 32.
