Description

       

  (Zusatzpatent zum Hauptpatent 425 684)         Streusichter,    insbesondere zum Sichten von Zement    Die Erfindung     betrifft    einen     Streusichter    zur Tren  nung eines Gemisches von Grobgut und Feingut, insbe  sondere zum Sichten von Zement, nach dem Patentan  spruch des Hauptpatentes.  



  Eine Verbesserung des     Streusichters    nach dem Haupt  patent wird dadurch erreicht, dass bei Anordnung von  die Zapfen der     Leitschaufeln    miteinander verbindenden,  einen     Gleichlauf    der     Verdrehbewegung    der     Leitschau-          feln    bewirkenden Getriebeteilen eine diese Getriebeteile  umgebende Haube vorgesehen ist.  



  Die einzige Figur der Zeichnung zeigt als Ausfüh  rungsbeispiel einen     Axialschnitt    durch einen     Streusich-          ter    mit den Merkmalen des Hauptpatentes; bezüglich  der Bezugszeichen 1 bis 34 sei auf dessen Beschreibung  verwiesen.  



  Eine zusätzliche Verbesserung besteht darin, dass eine  die Getriebeteile 30, 31, 33 umgebende Haube 35 vor  gesehen ist.  



  Der von der Haube bzw. von einem Abschnitt des  inneren Gehäuses 3 umgrenzte Raum 36 ist über eine  Leitung 37 an eine nicht dargestellte Quelle von gefilter  ter Druckluft     anschliessbar.     



  Durch die Haube 35 werden die Getriebeteile 30, 31,  33 vor Zementstaub geschützt. Das Einbringen von ge  filterter Druckluft in den Raum 36 bringt einen zusätz  lichen Schutz, und es steht dafür in der Zementindustrie  ohnehin stets eine geeignete     Druckluftquelle,    beispiels  weise eine solche für eine pneumatische     Fördervorrich-          tung,    zur Verfügung. Die Vorteile der erfindungsgemäs-         sen    Massnahmen bestehen sowohl bei einer Anordnung  der Getriebeteile 30, 31, 33 in der     Abscheidekammer     18, wie in der Zeichnung dargestellt, als auch bei einer  Anordnung aussen am äusseren Gehäuse 1.



  (Additional patent to the main patent 425 684) Scatter sifter, in particular for sifting cement The invention relates to a scatter sifter for separating a mixture of coarse and fine material, in particular special for sifting cement, according to the claim of the main patent.



  An improvement of the spreader according to the main patent is achieved by providing a hood surrounding these gear parts with the arrangement of gear parts connecting the pins of the guide vanes to one another and causing the rotational movement of the guide vanes to run synchronously.



  The single figure of the drawing shows, as an exemplary embodiment, an axial section through a scatter filter with the features of the main patent; with regard to the reference numerals 1 to 34, reference is made to the description thereof.



  An additional improvement is that a hood 35 surrounding the gear parts 30, 31, 33 is seen.



  The space 36 delimited by the hood or by a section of the inner housing 3 can be connected via a line 37 to a source of filtered compressed air, not shown.



  The gear parts 30, 31, 33 are protected from cement dust by the hood 35. The introduction of filtered compressed air into the space 36 provides additional protection, and a suitable compressed air source is always available for this in the cement industry, for example one for a pneumatic conveying device. The advantages of the measures according to the invention exist both when the gear parts 30, 31, 33 are arranged in the separation chamber 18, as shown in the drawing, and when they are arranged on the outside of the outer housing 1.
