Description

Die Erfindung betrifft einen Schlackenbrecher mit einem Druckgehäuse, einer durch das Druckgehäuse hindurchgeführien drehbaren Welle mit mehreren, darauf im Abstand befestigten, im Betrieb rotierenden Schneidmessern, die auf der Welle winkelversetzt angeordnet sind, und mit mehreren, unter der Welle nebeneinander angeordneten feststehenden Schneidmessern, wobei jedes rotierende Schneidmesser im Brecherbereich zwischen zwei benachbarten feststehenden Schneidmessern hindurchgeführt ist. Der Schlackenbrecher kann am Auslauf eines Strahlungskühlers oder Vergasungsreaktors mit Quenchensektion mit einem unter Wasser stehenden Druckgehäuse angeordnet sein.The invention relates to a slag crusher with a pressure housing, one by the Rotatable shaft passed through the pressure housing with several, spaced thereon attached, rotating cutting blades that are angularly offset on the shaft are arranged, and with several, arranged side by side under the shaft fixed cutting knives, each rotating cutting knife in Crusher area between two adjacent fixed cutting knives is passed through. The slag crusher can be at the outlet of a radiation cooler or gasification reactor with a quench section with an underwater Pressure housing may be arranged.

Ein solcher Schlackenbrecher ist aus WO-A-86/05198 bekannt. Die rotierende Welle ist hierbei auf der vertikalen Mittellinie des Druckgehäuses, d.h. zentrisch angeordnet. Bei einem von der Anmelderin entwickelten ähnlichen Schlackenbrecher stauten sich die unzerkleinerten und zu großen Schlackenbrocken oberhalb der rotierenden Messer und wurden durch die zu kleine Öffnung zwischen den beidseitigen Leitblechen immer wieder nach oben gedrückt und den Messern nicht zugeführt. Es kam zu einem Materialstau oberhalb der rotierenden Welle, der zu einer Unterbrechung des Materialstromes und zur Beeinträchtigung einer geregelten Schlackenabfuhr und Schlackenzerkleinerung führte.Such a slag crusher is known from WO-A-86/05198. The rotating shaft is here on the vertical center line of the pressure housing, i.e. centrally arranged. at a slag crusher developed by the applicant was dammed up uncrushed and too large chunks of slag above the rotating knives and were always due to the too small opening between the baffles on both sides pushed up again and not fed to the knives. One came Material jam above the rotating shaft, which leads to an interruption of the Material flow and to impair regulated slag removal and Slag crushing led.

Die Aufgabe der Erfindung besteht daher darin, die Schneidwerkzeuge so anzuordnen, dass sowohl kleine als auch große Schlackenstücke vollständig erfasst werden und eine geregelte Zerkleinerung und Abfuhr der Schlacke aus dem Schlackenbrecher erfolgt.The object of the invention is therefore to arrange the cutting tools in such a way that both small and large pieces of slag are completely covered and one controlled crushing and removal of the slag from the slag crusher.

Die Lösung der Aufgabe erfolgt durch die Merkmale des Patentanspruchs 1, die Unteransprüche stellen vorteilhafte Ausgestaltungen der Erfindung dar.The problem is solved by the features of claim 1, the Subclaims represent advantageous embodiments of the invention.

Durch die erfindungsgemäße Anordnung und Ausführung der rotierenden und feststehenden Messer ist eine geregelte Materialzufuhr zu den Brechstellen gewährleistet. Durch die An- und Zuordnung der Schneid- und Festmesser und deren Abstände zueinander wird ein gutes Brechergebnis sowie eine hohe Brechleistung erreicht. Due to the arrangement and design of the rotating and fixed knife is a controlled material supply to the breaking points guaranteed. By assigning and assigning the cutting and fixed knives and their Distances to each other are a good crushing result as well as a high crushing performance reached.

Die feststehenden Schneidmesser weisen einen langen und einen kurzen Schenkel auf. In das feststehende Schneidmesser ist auf der Seite des langen Schenkels eine in eine Gerade übergehende kreisbogenförmige Ausnehmung und auf der Seite des kurzen Schenkels nur eine kreisbogenförmige Ausnehmung, bezogen auf die vertikale Mittelachse des Druckgefäßes, eingebracht. Die feststehenden Schneidmesser sind innerhalb des Druckgefäßes auf Konsolen lösbar befestigt; die Dimensionierung des langen und kurzen Schenkels ist von der Lage des Festmessers zur Außenwand des Druckgefäßes abhängig, wobei die Länge eines jeden feststehenden Messers von der Anordnung zur Mittelachse sowie zur Anordnung gegenüber der runden Wand des Druckgefäßes in der Schneidposition innerhalb des Druckgefäßes abhängig ist.The fixed cutting knives have a long and a short leg. In the fixed cutting knife on the side of the long leg is one in one Straight merging circular arc and on the side of the short Leg only an arcuate recess, based on the vertical Center axis of the pressure vessel introduced. The fixed cutting knives are releasably attached to consoles within the pressure vessel; the dimensioning of the long and short leg is from the position of the fixed knife to the outer wall of the Pressure vessel dependent, the length of each fixed knife of the Arrangement to the central axis and to the arrangement opposite the round wall of the Pressure vessel is dependent in the cutting position within the pressure vessel.

Sowohl die Schneid- als auch die Festmesser sind im Schneidbereich einem großen Verschleiß ausgesetzt. Both the cutting and the fixed knives are large in the cutting area Exposed to wear.

Aus diesem Grunde werden diese Bereiche mit einem Verschleißschutz versehen. Dieser Verschleißschutz kann durch eine Auftragsschweißung oder durch einen mechanisch aufgebrachten Verschleißschutz erzielt werden. Natürlich können sämtliche Messer auch als komplette Einheit ausgetauscht werden, wenn durch langanhaltenden schleißenden Betrieb ein Verschleiß der Grundkörper der Messer aufgetreten ist.For this reason, these areas are combined with a Wear protection provided. This wear protection can by build-up welding or by mechanical applied wear protection can be achieved. Of course, all knives can also be complete Unit can be replaced when long-lasting abrasive operation a wear of the main body of the Knife has occurred.

Die Durchtritte der Antriebswelle durch das Druckgefäß werden durch spezielle Stopfbuchsen mit einem Schmier- bzw. Spülsystem abgedichtet. Die Lagerung und Antrieb der Antriebswelle ist außerhalb des Druckgefäßes angeordnet. Die durch das Druckgehäuse hindurchgeführte Welle ist im Abstand "a" zur vertikalen und zur horizontalen Mittelachse angeordnet.The drive shaft passes through the pressure vessel are replaced by special glands with a lubricating or flushing system sealed. The storage and drive the drive shaft is outside the pressure vessel arranged. The led through the pressure housing Wave is at a distance "a" to the vertical and to the horizontal central axis.
