Description
Die Erfindung betrifft ein Verfahren zum Ermitteln und Ausscheiden von unzerkleinerbaren Fremdkörpern aus vorzerkleinertem Rohgut, wie es in der Hauptpatentanmeldung W 29231III/50 c beschrieben ist. Bei dem Verfahren nach der Hauptpatentanmeldung betätigt der als Überlastungsschutz eingerichtete Teil einer Vorzerkleinerungsmaschine, die den Fremdkörper hindurchgehen läßt, beim Überschreiten einer bestimmten Stückgröße des Fremdkörpers einen Schalter od. dgl., durch den der Antrieb des nachgeschalteten Förderers oder Weiterbehandlungsaggregates verlangsamt oder stillgesetzt wird, gegebenenfalls unter gleichzeitiger Abgabe eines Signals, oder es werden hierbei Einrichtungen betätigt, die den den Fremdkörper enthaltenden Gutstrom zeitweilig ablenken, um den Fremdkörper aus dem Verfahrensgang auszuscheiden.The invention relates to a method for determining and removing foreign bodies that cannot be comminuted from pre-shredded raw material, as described in the main patent application W 29231III / 50 c is. In the process according to the main patent application, the one set up as overload protection operates Part of a pre-shredding machine that allows the foreign body to pass through when it crosses a certain piece size of the foreign body a switch od. Like., Through which the drive of the downstream Conveyor or further processing unit is slowed down or shut down, if necessary with simultaneous delivery of a signal, or it is operated here facilities that the Temporarily deflect the flow of material containing foreign bodies to remove the foreign body from the process to be eliminated.
Handelt es sich bei dem Fremdkörper um ein Eisenstück oder ein sonstiges magnetisch beeinflußbares Material, so geschieht das Herausholen zweckmäßigerweise mit Hilfe einer Magnettrommel oder mittels eines Aushebemagneten. Es wäre nun unzweckmäßig und wirtschaftlich nicht vertretbar, wenn derartige Magnetscheider im Hinblick auf die gelegentlich auftretenden übergroßen Eisenteile ständig unter Spannung gehalten würden. In weiterer Ausgestaltung des Gedankens der Hauptpatentanmeldung besteht daher die Erfindung darin, daß der vom Überlastungsschutz der Vorzerkleinerungsmaschine betätigte Schalter einen Eisenausscheider (Magnetrolle, Aushebemagnet) einschaltet, der dann nach Abwerfen des ausgehobenen Eisenteiles über ein Zeitrelais wieder geschlossen wird. Auf diese Weise ist der Eisenausscheider nur von Fall zu Fall in Betrieb.If the foreign body is a piece of iron or something else that can be influenced magnetically Material, the removal is expediently done with the help of a magnetic drum or by means of a lifting magnet. It would be inexpedient and economically unreasonable if such magnetic separators with regard to the occasionally occurring oversized iron parts constantly would be kept under tension. In a further development of the idea of the main patent application The invention is therefore that of the overload protection of the pre-shredding machine actuated switch switches on an iron separator (magnetic roller, lifting magnet), which then follows Discarding the excavated iron part is closed again via a time relay. That way is the iron separator is only in operation on a case-by-case basis.
Die Erfindung kann weiterhin dahingehend ausgestaltet werden, daß in dem Fall, in welchem die Magnettrommel oder der Aushebemagnet ständig in Betrieb gehalten wird, um aus dem auf dem Fördermittel bewegten Gut laufend Eisenteile auszuheben, der vom Überlastungsschutz betätigte Schalter die Felderregung des Eisenausscheiders kurzzeitig erhöht, wenn ein übergroßes Eisenstück durch die Vorzer-The invention can also be designed in such a way that in the case in which the Magnet drum or the lifting magnet is kept in constant operation to get off the conveyor Moving goods continuously to dig out iron parts, the switch actuated by the overload protection the Field excitation of the iron separator is briefly increased when an oversized piece of iron is
