Description

  

  Zerkleinerungseinrichtung.    Die Erfindung     betrifft    eine Zerkleinerungs  einrichtung mit einer     Schneidvorrichtung    für  von einer Flüssigkeit mitgeführte feste Stoffe,  wobei eine bevorzugte Anwendung diejenige  für Abwasseranlagen ist.  



  Die Erfindung besteht darin, dass eine in  axialer Richtung fördernde     Schneidvorrich-          tung    vorgesehen ist, an welche sich auf deren  Druckseite ein Gehäuse mit um einen zen  tralen Teil angeordnetem     Sammelkanal    mit  seitlichem Austritt anschliesst.  



  Auf der Zeichnung ist ein Ausführungs  beispiel der Erfindung schematisch dargestellt.       Fig.    1 zeigt die Zerkleinerungseinrichtung  zum Teil im Längsschnitt,       Fig.    2 einen Schnitt nach Linie     II-11    in       Fig.    1 durch das Gehäuse.  



  Die Zerkleinerungseinrichtung ist mit dem  Saugstutzen 1 an eine Leitung oder einen  Schacht (nicht gezeichnet) angeschlossen, durch  welchen die feste Stoffe mitführende Flüssig  keit zugeführt wird. Das Gehäuse 2, das als  Ringgehäuse mit radialem Austritt 3 ausge  bildet ist, ist auf der Druckseite des in axi  aler Richtung fördernden, auf der Welle 4       aufgekeilten        Schneidmessers    5 vorgesehen.  Durch die Mutter 6 festgehalten, arbeitet das       Schneidmesser    5 mit dem Rost 7 mit den  Öffnungen 8 zusammen. Die Welle 4 ist in  dem Längslager 9 gelagert und am Austritt  aus dem Gehäuse 2 durch die Stopfbüchse 10  abgedichtet.

   Die Laterne 11 mit den Öffnun  gen 12 enthält ein     Spurlager,    durch welches  das     Messer    5 axial gehalten ist     und    das    durch Drehen des Handrades 13 zum Ein  stellen des Spiels zwischen Messer 5 und  Rost 7 axial verschoben werden kann. Das  Gegenmesser 14 ist mittels der Schrauben 15  einstellbar.  



  Beim Zerkleinern der festen Stoffe aus  Abwässern ist die Beanspruchung der Schneid  vorrichtung sehr verschieden, wobei Stösse,  die das     Schneidmesser    und dessen Antriebs  welle schlagartig belasten, oft vorkommen  und sogar das Messer plötzlich blockiert wird.  In dem letztgenannten Fall muss meist das  Gehäuse geleert werden, was zuerst durch  Spülen geschieht und darnach mit der Hand  durch Reinigungsöffnungen.  



  Das den zentralen Teil des Gehäuses 2  bildende Längslager 9 stützt sich mittels  kräftiger Rippen 16 auch auf der Seite des  rotierenden Messers gegen den äussern Teil  des Gehäuses 2, so dass im Gegensatz zu be  kannten Anordnungen jegliche schlagartigen  Beanspruchungen unmittelbar an der Ent  stehungsstelle aufgenommen und auf das Ge  häuse 2 bzw. über den Stutzen 17 aufs Fun  dament bei waagrechter Anordnung abgeleitet  werden.

   Vor allem ergibt sich der grosse  Vorteil sowohl durch das axial fördernde       Schneidmesser    5 als auch durch das Ring  gehäuse 2, dass die Länge der Welle 4 bis  zum Ende 18, auf welches die Kupplung des  Antriebsmotors     aufgekeilt    wird, so kurz als  möglich gestaltet werden kann und die Welle  4 praktisch ausschliesslich auf     Torsion    bean  sprucht wird, Zudem ermöglicht der kleine      Rauminhalt des Gehäuses 2 ein leichteres  und rascheres Reinigen und somit eine Kür  zung des     Betriebsunterbruches.     



  Anstatt dass das Gehäuse ein Ringgehäuse  mit radialem Austritt ist, kann auch ein       Spiralgehäuse    mit     tangentialem    Austritt ver  wendet werden.



  Shredding device. The invention relates to a comminution device with a cutting device for solid substances carried along by a liquid, a preferred application being that for sewage systems.



  The invention consists in providing a cutting device which is conveying in the axial direction and to which a housing with a collecting channel arranged around a central part and a lateral outlet is connected on its pressure side.



  In the drawing, an embodiment example of the invention is shown schematically. Fig. 1 shows the comminution device partly in longitudinal section, Fig. 2 shows a section along line II-11 in Fig. 1 through the housing.



  The shredding device is connected with the suction nozzle 1 to a line or a shaft (not shown) through which the solids entrained liquid is fed. The housing 2, which is formed out as a ring housing with a radial outlet 3, is provided on the pressure side of the cutting knife 5 wedged onto the shaft 4, which is conveying in the axial direction. Held by the nut 6, the cutting knife 5 works together with the grate 7 with the openings 8. The shaft 4 is mounted in the longitudinal bearing 9 and sealed at the outlet from the housing 2 by the stuffing box 10.

   The lantern 11 with the openings 12 contains a thrust bearing through which the knife 5 is held axially and which can be moved axially by turning the handwheel 13 to set the game between knife 5 and grate 7. The counter knife 14 is adjustable by means of the screws 15.



  When comminuting the solids from waste water, the stress on the cutting device is very different, with shocks that suddenly load the cutting knife and its drive shaft, often occur and even the knife is suddenly blocked. In the latter case, the housing usually has to be emptied, which is done first by rinsing and then by hand through cleaning openings.



  The longitudinal bearing 9, which forms the central part of the housing 2, is supported by means of strong ribs 16 on the side of the rotating knife against the outer part of the housing 2, so that, in contrast to known arrangements, any sudden stresses are recorded and applied directly to the point of origin the Ge housing 2 or via the nozzle 17 on the Fun dament can be derived with a horizontal arrangement.

   Above all, there is the great advantage of both the axially conveying cutting knife 5 and the ring housing 2 that the length of the shaft 4 to the end 18, on which the coupling of the drive motor is keyed, can be made as short as possible and the shaft 4 is practically exclusively based on torsion bean, In addition, the small volume of the housing 2 enables easier and faster cleaning and thus a shortening of the interruption of operation.



  Instead of the housing being an annular housing with a radial outlet, a spiral housing with a tangential outlet can also be used.
