Description
15 20 25 30 35 40 7712674-6 a Det önskade resultatet erhålles genom att anord- ningen ges de kännetecken som framgår av det efterföljande patent- kravet 1. ' V En utföringsform av anordningen_eñligt§ü§pfinningen beskrives i det följande närmare med hänvisning till bifogade rit- ningar. The desired result is obtained by giving the device the features which appear from the appended claim 1. An embodiment of the device according to the invention is described in more detail below with reference to attached drawings.
Fig. 1 är en vy av anordningen sedd uppifrån.Fig. 1 is a view of the device seen from above.
Pig. 2 är en avkortad och delvis uppskuren sidovy av samma anordning.Pig. 2 is a truncated and partially cut-away side view of the same device.
Pig. 3 visar ett tvärsnitt enligt III - III i fin. 2 genom anordningen.Pig. 3 shows a cross section according to III - III in fin. 2 through the device.
Den illustrerade anordningen är ett skivsåll för flis med en stomme 1 som samtidigt bildar sållets hölje.The illustrated device is a disc sieve for chips with a body 1 which at the same time forms the cover of the sieve.
Ett flisinlopp 2 är anordnat i höljets ena gavel- ände och ett utlopp 3 för grovflis i dess motsatta gavelände. Nedåt har höljet en uttagsöppning U för material som fallit genom sållet, såväl prima flis som sållspån.A chip inlet 2 is arranged at one end of the casing and an outlet 3 for coarse chips at its opposite end of the housing. Downwards, the casing has an outlet opening U for material that has fallen through the sieve, both fine chips and sieve chips.
.(' Mellan inloppet 2 och utloppet 3 löper en passage 5, vilken nedåt är begränsad av ett stort antal i flera rader 6 anord- nade skivor 7. Skivorna 7 i varje rad är anordnade på en gemensam axel 8 och drivna via denna medelst på ritningen endast schematiskt antydda drivorgan 9. Skivorna i varje rad ingriper så med lämpligt spel i mellanrum mellan skivorna i den angränsande raden respektive de på_ömse sidor belägna angränsande raderna, att skivorna tillsam- mans'bi1dar ett självrensandë såIl.som sträcker sig utmed passagen.Between the inlet 2 and the outlet 3 runs a passage 5, which is delimited downwards by a large number of discs 7 arranged in several rows 6. the discs only schematically indicated drive means 9. The discs in each row engage with suitable clearance in the spaces between the discs in the adjacent row and the adjacent rows located on the opposite sides, so that the discs together form a self-cleaning sand so as to extend along the passage.
Skivradernas 6 axlar 8 är orienterade i passagens 5 genommatningsriktning för materialet och så placerade, i tvärsnitt enligt fig. 3 sett, att de lokaliserar skivorna i trågliknande formation. Passagens botten och - till olika höjd - dess sidor av- gränsas härigenom av skivraderna 6. ' I Skivorna är drivna i sådan rotationsriktning (enligt pilen A) att deras periferirörelse, där de avgränsar passagen 5, bibringar det på skivorna eller mot dessa anliggande flisflödet ge- nom passagen en omvälvningsrörelse tvärledes mot och uppåt utefter passagens ena sida (antydd med pilen B) under flisflödets samtidiga rörelse mot utloppet 3. Det upplyfta materialet faller inåt-nedåt mot skivorna och omvälvningsrörelsen upprepas så att grovflis, som ej kan falla ned genom sållet beskriver en skruvlinjeartad bana ge- nom passagen 5 och effektivt separeras från finare flis och sållspån.The shafts 8 of the disc rows 6 are oriented in the feed direction 5 of the passage 5 for the material and are placed, in cross section according to Fig. 3, so that they locate the discs in trough-like formation. The bottom of the passage and - to different heights - its sides are hereby delimited by the rows of discs 6. 'In the discs are driven in such a direction of rotation (according to arrow A) that their circumferential movement, where they delimit the passage 5, imparts through the passage a reversal movement transversely to and upwards along one side of the passage (indicated by the arrow B) during the simultaneous movement of the chip flow towards the outlet 3. The raised material falls inwards-downwards towards the discs and the reversal movement is repeated so that coarse chips which cannot fall through the sieve describes a helical path through the passage 5 and is effectively separated from finer chips and sieve chips.
Samtliga skivraderna är lämpligen inrättade gemensamtAll disc rows are suitably arranged together
