Description

Verfahren zum Ermitteln und Ausscheiden von unzerkleinerbaren Fremdkörpern aus vorzerkleinertem Rohgut Die Erfindung betrifft ein Verfahren zum Ermitteln und Ausscheiden von unzerkleinerbaren Fremdkörpern aus vorzerkleinertem Rohgut. Bei der Vorzerkleinerung von Rohgut tritt häufig der Fall ein, daß sich in diesem unzerkleinerbare Fremdkörper großer Abmessungen befinden, die einen Bruch an der Zerkleinerungsmaschine herbeiführen. Aus diesem Grunde werden derartige Maschinen mit einem Überlastungsschutz ausgerüstet, der die gefährdeten Teile der Maschine so weit ausweichen läßt, daß ein Zubruchgehen vermieden wird, wobei sich allerdings der Fremdkörper in der Maschine festsetzt. In einem solchen Fall wird dann die Zerkleinerungsmaschine außer Betrieb gesetzt, und der Fremdkörper muß in langwieriger und mühseliger Arbeit ausgeräumt oder sogar herausgebrannt werden. Es wird auf diese Weise die der Vorzerkleinerung nachgeschaltete Apparatur zwar vor Beschädigungen durch den Fremdkörper bewahrt, jedoch auf Kosten einer längeren Betriebsunterbrechung und eines zusätzlichen Arbeitsaufwandes.Procedure for identifying and eliminating foreign bodies that cannot be crushed from pre-shredded raw material The invention relates to a method for determining and Separation of non-shredded foreign bodies from pre-shredded raw material. at the pre-shredding of raw material often occurs that in this uncrushable Large foreign bodies are located that could break the shredder bring about. For this reason, such machines are provided with an overload protection equipped, which allows the endangered parts of the machine to evade so far that Breaking is avoided, although the foreign body is in the machine sets. In such a case, the shredding machine is then out of operation set, and the foreign body has to be cleared away in tedious and arduous work or even burned out. In this way, it becomes that of pre-shredding downstream equipment is protected from damage by the foreign body, but at the expense of a longer business interruption and additional work.

Nun gibt es aber auch Vorzerkleinerungsmaschinen mit Überlastungsschutz, bei denen Teile der Brechwerkzeuge so weit ausweichen können, daß der Fremdkörper von selbst wieder freigegeben wird. Eine solche Vorzerkleinerungsmaschine bleibt somit zwar im Betrieb, aber der freigegebene Fremdkörper gefährdet jetzt die nachgeschalteten Förder- oder Weiterbehandlungsaggregate, da diese für das normal vorgebrochene Gut ausgelegt sind.But now there are also pre-shredding machines with overload protection, in which parts of the breaking tools can move so far that the foreign body is released again by itself. Such a pre-shredding machine remains thus in operation, but the released foreign body now endangers the downstream Conveying or further processing units, as these are for the normally pre-broken goods are designed.

Hier greift nun die Erfindung ein. Sie besteht darin, daß der als Überlastungsschutz eingerichtete Teil einer Vorzerkleinerungsmaschine, die den Fremdkörper hindurchgehen läßt, bei Überschreiten einer bestimmten Stückgröße des Fremdkörpers einen Schalter od. dgl. betätigt, durch den der Antrieb des nachgeschalteten Förder- oder Weiterbehandlungsaggregates verlangsamt oder stillgesetzt wird, gegebenenfalls unter gleichzeitiger Abgabe eines Signals, oder durch den Einrichtungen betätigt werden, die den den Fremdkörper enthaltenden Gutstrom zeitweilig ablenken.This is where the invention comes in. It consists in the fact that the as Overload protection set up part of a pre-shredding machine that removes foreign matter can pass, if a certain piece size of the foreign body is exceeded a switch or the like operated, through which the drive of the downstream conveyor or further treatment unit is slowed down or shut down, if necessary with simultaneous delivery of a signal, or actuated by the devices that temporarily deflect the flow of material containing the foreign body.

Es handelt sich somit bei der Erfindung darum, den Überlastungsschutz bzw. die Ausweichbewegung des nachgiebig gestalteten Teiles der Zerkleinerungsmaschine dazu zu benutzen, um die Stückgröße festzulegen, bis zu der Fremdkörper die nachgeschalteten Einrichtungen passieren dürfen. Auf diese Weise wird das Bedienungspersonal auf den Fremdkörper aufmerksam gemacht und dessen Transport so gesteuert, daß er entweder vom Bedienungspersonal fortgeschafft werden kann oder automatisch durch Ausfahren oder Schwenken des Fördermittels, Einlegen eines Abstreichers oder Überbrückung der Einlaufrutsche der Weiterbehandlungsapparatur abgeleitet wird.The invention is thus concerned with overload protection or the evasive movement of the resiliently designed part of the shredding machine to use to determine the size of the piece, up to the foreign body the downstream Bodies are allowed to pass. In this way the operator gets on made the foreign body aware and controlled its transport so that it either can be carried away by the operator or automatically by extending or pivoting the conveyor, inserting a scraper or bridging the inlet chute of the further treatment apparatus is derived.

Als besonders für die Zwecke der Erfindung geeignete Vorzerkleinerungsmaschine hat sich ein Einschwingenbrecher mit hydraulisch abgestützter Brechschwinge erwiesen (deutsche Patentschrift 1069 994). Bei diesem stützt sich die Brechschwinge über eine Druckplatte an einer unter Flüssigkeitsdruck stehenden Traverse ab, deren Ausweichbewegung zur Einleitung der notwendigen Schaltbewegungen benutzt wird. Nach Ansprechen eines Zeitrelais wird dann der normale Betriebszustand wiederhergestellt.A single toggle crusher with a hydraulically supported crusher rocker has proven to be a particularly suitable pre-shredding machine for the purposes of the invention (German patent specification 1069 994). In this case, the crushing rocker is supported by a pressure plate on a cross-member under fluid pressure, the evasive movement of which is used to initiate the necessary switching movements. After a time relay has responded, the normal operating state is restored.
