Description
Die Erfindung betrifft einen Hackschnitzelreiniger nach dem Oberbegriff des Anspruchs 1.The invention relates to a wood chip cleaner the preamble of claim 1.
In bekannten Hackschnitzelreinigern dieser Art erfolgt das Anreichern des schweren Materials durch Rütteln und Luft einblasen oder Einblasen von Wasser. Hierbei ist ein beträchtlicher Energieaufwand erforderlich. Bei Verwendung von Wasser ergibt sich ein Anstieg der Hackschnitzelfeuchte, wobei zudem das Wasser gereinigt werden muß.This is done in known wood chip cleaners of this type Enrich the heavy material by shaking and air blowing or blowing water. Here is a considerable energy expenditure required. Using of water there is an increase in the wood chip moisture, the water must also be cleaned.
Der Erfindung liegt die Aufgabe zugrunde, einen Hackschnitzel reiniger der eingangs angegebenen Art so auszubilden, daß er mit einem geringeren Energieaufwand betrieben und auf die Verwendung von Wasser verzichtet werden kann.The invention has for its object a wood chips to train cleaners of the type specified at the beginning, that he operated with less energy and the use of water can be dispensed with.
Diese Aufgabe wird durch die Merkmale im Kennzeichen des Anspruchs 1 gelöst. Hierdurch kann das in dem Hackgut vor handene schwere Material äußerst effektiv mit geringem Energieaufwand angereichtert und aus dem reinen Hackschnitzel strom entfernt werden.This task is characterized by the characteristics of the Claim 1 solved. This can be done in the wood chips existing heavy material extremely effective with little Energy expenditure enriched and from the pure wood chips electricity are removed.
Die Erfindung wird nachfolgend anhand der Zeichnung bei spielsweise näher erläutert. Es zeigtThe invention is described below with reference to the drawing explained in more detail, for example. It shows
Fig. 1 das Hackschnitzelsieb in Seitenansicht, Fig. 1, the Hackschnitzelsieb in side view,
Fig. 2 das Hackschnitzelsieb in einer Draufsicht, und Fig. 2, the wood chip screen in a plan view, and
Fig. 3 einen Schnitt längs der Linie III-III in Fig. 2. Fig. 3 is a section along the line III-III in Fig. 2.
Der Hackschnitzelreiniger besteht aus einem kastenartigen Hauptsieb 1 mit Siebebenen 2, 3, wobei das Großsieben des Hackgutes durch eine kreisförmige Siebbewegung in der Horizontalebene stattfindet. Anschließend an das Hauptsieb folgt ein Schwermaterialanreicherer 4, in dem das schwere Material angereichtert und von dem reinen Hackschnitzelstrom getrennt wird. Der Schwermaterialanreicherer 4 stellt eine mit dem Hauptsieb in der Horizontalebene mitbewegte Ebene dar, in deren einer hinteren Ecke eine Abscheide öffnung 7 für das schwere Material angeordnet ist. In dieser Ebene sind vor einer querverlaufenden Schwelle 8 Leisten 6 so schrägliegend angeordnet, daß sie das schwere Material zu der Abscheideöffnung 7 leiten, während sich das reine Hackschnitzelmaterial über die Schwelle zur Austrittsöffnung 9 des Hackschnitzelsiebs bewegt.The wood chip cleaner consists of a box-like main sieve 1 with sieving levels 2, 3 , the bulk sieving of the wood chips taking place by means of a circular sieving movement in the horizontal plane. Following the main sieve is a heavy material enrichment device 4 , in which the heavy material is enriched and separated from the pure stream of wood chips. The heavy material enricher 4 represents a plane moving with the main sieve in the horizontal plane, in the rear corner of which a separating opening 7 for the heavy material is arranged. In this plane 8 strips 6 are arranged obliquely in front of a transverse threshold that they guide the heavy material to the separating opening 7 , while the pure wood chip material moves over the threshold to the outlet opening 9 of the wood chip screen.
Dadurch, daß das vom Hauptsieb 1 in den Anreicherer 4 gelangende Hackgut sowohl durch Siebbewegung in der Hori zontalebene als auch die Wirkung der Leisten 6 in eine Rüttelbewegung versetzt wird, erfolgt eine sehr effektive Anreicherung des schweren Materials aus dem Hackschnitzelstrom. Das schwere Material kommt an der Schwelle 8 zum Stillstand und wird mit Hilfe der schrägen Leisten 6 zur Abscheideöffnung 7 geleitet. Der reine Hackschnitzelstrom bewegt sich über die Schwelle 8 hin weg und von dort weiter zur Austrittsöffnung 9 des Hack schnitzelsiebs.Characterized in that the wood chips coming from the main sieve 1 into the enricher 4 are moved both by sieve movement in the horizontal plane and the effect of the strips 6 in a shaking movement, a very effective enrichment of the heavy material from the wood chip stream takes place. The heavy material comes to a standstill on the threshold 8 and is guided to the separation opening 7 with the aid of the inclined strips 6 . The pure stream of wood chips moves away over the threshold 8 and from there further to the outlet opening 9 of the wood chip screen.
Mit 10 ist ein Rüttler bezeichnet, der zur Erhöhung der Anreicherungswirkung die Kreisbewegung des Anreicherers 4 in der Hoirzontalebene durch eine vertikale Rüttelbewegung überlagert.With 10 a vibrator is designated, which overlaps the circular movement of the enrichment 4 in the horizontal plane to increase the enrichment effect by a vertical shaking movement.
