Description
Vorrichtung zumr Ausscheiden von Holz- und Eisenstücken aus Fördergut In den Brikettfabriken der Braunkohlenindustrie werden in. großem Umfange Bänder verwendet, welche die 'Rohkohle aus der Grube Zerkleinerungsmaschinen, Sieben u. d-1. zuführen. Die Rohbraunkohle enthält dabei je nach der natürlichen Kohlenbeschaffenheit und den zur Verwendung gelangenden Gewinnungsgeräten Komgrößenanteile in den verschiedensten Ausmaßen. Der sog. Lignit,o,der das Kohlenholz fällt dabei in langen Stücken an. Es ist auch nicht zu vermeiden, daß größere Eisenstücke, z. B. Eimerzinken, Nageleisen u. dgl., mit der Kohle ankommen. Diese Kohlen- und Eisenstücke können zu erheblichen Störungen führen.Device for separating pieces of wood and iron from conveyed goods In the briquette factories of the lignite industry, ribbons are produced on a large scale used, which the 'raw coal from the pit crushing machines, sieves u. d-1. respectively. The raw lignite contains depending on the natural properties of the coal and the extraction devices used in the most varied of grain sizes Dimensions. The so-called lignite, oh, the coal wood, falls in long pieces. It is also inevitable that larger pieces of iron, e.g. B. Bucket prongs, nail irons and the like, arrive with the coal. These pieces of coal and iron can become significant Malfunctions.
Ein Eisenstück beispielsweise kann nach beiliegender Zeichnung durch den Vorbrecher lz, dessen Rollen federnd und nachgiebig gelagert sind, hindurchgelangen, ohne im - Vorhrecher selbst Zerstörungen anzurichten. Wenn der Abstand. der Brecherwalzen über dem darunterliegenden Band i jedoch aus baulichen Gründen nicht genügend ,groß ist, dann wird dieses in strichpunktierten Linien dargestellte Eisenstück b eine etwa senkrechte Lage einnehmen und in dieser Stellung das Förderband! aufschlitzen.A piece of iron, for example, can go through according to the accompanying drawing the primary crusher lz, the rollers of which are spring-loaded and flexible, can pass through it, without causing damage in the Vorhrecher himself. When the distance. the crusher rollers above the volume i below, however, for structural reasons, it is not large enough is, then this iron piece b shown in dash-dotted lines becomes a assume an approximately vertical position and in this position the conveyor belt! slit open.
Die großen Holzstücke, die im Vorbrecher zwar verkleinert werden, sind in der zerkleinerten Kohle aus Fabrikationsgründen unerwünscht, außerdem belasten sie den Vorbrecher /t.The large pieces of wood that are reduced in size in the primary crusher are undesirable in the crushed coal for manufacturing reasons, and also pollute they the primary crusher / t.
Das Ausscheiden derartiger Beimengungen, die eine größere- Länge als das Fördergut haben, erfolgt ;gemäß der Erfindung mittels einer einfachen Vorrichtung, welche dadurch gekennzeichnet ist, daß an der Abwurfstelle, eines Förderers eine leicht drehbare Rolle angeordnet ist.The excretion of such admixtures that are longer than have the conveyed, takes place; according to the invention by means of a simple device, which is characterized in that at the dropping point, a conveyor a easily rotatable roller is arranged.
Die Kohle wird durch ein Transp!ortbanid a mit einer bestimmten Geschwindigkeit herangeschafft und vor Kopf in einer Wurfparabel abgegeben, deren Gestalt von der Geschwindigkeit des Bandes ,a abhängig ist. Im Abstandy, der beispielsweise 70o mm betragen kann, befindet sich eine kleine, leicht drehbare Rolle/, die zweckmäßig von Kugellagetn getragen wird. Die Mittelachse dieser Rolle, liegt in der ,gleichen Höhe wie die, Mittelachse der Bandtrommel c.The coal is transported by a transp! Ortbanid a at a certain speed brought up and delivered in front of the head in a trajectory parabola, the shape of which depends on the Speed of the belt, a is dependent. At a distance of y, for example 70o mm, there is a small, easily rotatable Role/, which is expediently carried by ball bearings. The central axis of this role lies at the same height as the central axis of the belt drum c.
Kommen nun im Kohlenstrom g, wie vorher geschildert, unerwünschte B:eimen;guing:,n mit größerer Länge an, so wird der Kohlenstrom zwischen der Rolle f und ,der Bandrolle c hindurchgeschleust, während die längeren Stücke b, die auf der Kohle schwimmen, über. die Rolle f durch die öffnung e der Schurre d ausgeschleust werden. Dicr richtige Abstand der Rolle f von .der Trommel c muß durch Versuche festgelegt werden. Zu diesem Zwecke sind die Lager der Rolle f in waagerechter Richtung einstellbar angeordnet.Now come in the coal stream g, as previously described, undesirable B: eimen; guing:, n with greater length, the coal flow between the roll f and, the tape roll c passed through, while the longer pieces b, which are on the coal swim over. the roll f is discharged through the opening e of the chute d will. The correct distance between the roller f and the drum c must be carried out through experiments be determined. For this purpose, the bearings of the roller f are in the horizontal direction adjustable arranged.
