Abstract

The breaker for crushing rocks and stone etc has a discharge conveyor device with associated magnetic belt separator. A switching element (12) is mounted in the conveyor direction (X) in front of the separator (7) or at its inlet edge. This is so that the discharge conveyor device is switched off when the material layer in front of the magnetic separator exceeds the designated spacing between the conveyor belt (6) of the discharge conveyor and the magnetic belt separator (7). The switch (12), which may be a sensor, is operated by a swivel mounted lever (11).

Description

Die vorliegende Erfindung bezieht sich auf eine Einrichtung zum Zerkleinern von Material, insbesondere Gestein, sowie Bau- und Straßenbaumaterial, mit einem Brechwerk zur Zerkleinerung des Materials und einer Förder- und Ausgabeeinrichtung für das zerkleinerte Material, wobei der Förder- und Ausgabeeinrichtung ein Magnetbandabscheider zugeordnet ist.The present invention relates to a device for shredding material, in particular stone, and construction and road construction material, with a crusher for shredding the material and a conveying and dispensing device for the shredded material, the conveying and dispensing device being assigned a magnetic tape separator .

Einrichtungen der gattungsgemaßen Art sind bekannt (vergleiche Firmenprospekt KLEEMANN + REINER: Raupenmobiler Universal-Prallbrecher MOBIREX, info 9230-d) und haben sich im Großen und Ganzen auch bewährt. Ein Problem tritt dann auf, wenn die Höhe der auf dem Förderband unter dem Magnetbandabscheider der vorbeigeführten Materialschicht höher als der Abstand des Magnetbandabscheiders zum Förderband ist wird und der Magnetbandabscheider und/oder das Austragsförderband beschädigt werden kann. Diese Gefahr besteht insbesondere dann, wenn auf dem Förderband Schrott, insbesondere Eisenknäuel befördert werden.Facilities of the generic type are known (see company brochure KLEEMANN + REINER: Crawler-mobile universal impact crusher MOBIREX, info 9230-d) and have also proven themselves on the whole. A problem arises when the height of the material layer on the conveyor belt under the magnetic belt separator is higher than the distance between the magnetic belt separator and the conveyor belt and the magnetic belt separator and / or the discharge conveyor belt can be damaged. This danger exists in particular when scrap, in particular iron balls, are transported on the conveyor belt.

Auszugehen ist dabei davon, daß der Magnetbandabscheider relativ zum Förderband in einem bestimmten Abstand aufgehängt werden muß, um seine bestimmungsgemäße Aufgabe erfüllen zu können, wenn Schrott unmittelbar vom Förderband ausgehoben werden soll. Andererseits hat der einem Aufgabetrichter der Brecheranlage nachgeordnete Zuführkanal eine Höhe, die im allgemeinen etwa doppelt so hoch wie der genannte Abstand des Magnetbandabscheiders ist, damit sich das in der Prallmühle zugeführte Material "ordnen" kann.It must be assumed that the magnetic belt separator must be suspended at a certain distance from the conveyor belt in order to be able to fulfill its intended purpose if scrap is to be lifted off the conveyor belt. On the other hand, the a feed channel arranged downstream of a feed hopper of the crusher system, a height which is generally approximately twice as high as the distance of the magnetic tape separator, so that the material fed into the impact mill can "order".

Die der vorliegende Erfindung zugrunde liegende Aufgabe besteht darin, eine Einrichtung der gattungsgemäßen Art so aufzurüsten, daß eine Beschädigung des Magnetbandabscheiders und auch des Förderbands aufgrund übergroßer Teile sicher ausgeschaltet wird.The object on which the present invention is based is to upgrade a device of the generic type in such a way that damage to the magnetic tape separator and also to the conveyor belt is reliably eliminated due to oversized parts.

Diese Aufgabe wird dadurch gelöst, daß in Förderrichtung (X) der Förder- und Ausgabeeinrichtung betrachtet vor dem Magnetbandabscheider (7) oder an dessen Zulaufkante ein Schaltelement (Schalter 12) angeordnet ist, über welches die Förder- und Ausgabeeinrichtung und der Magnetbandabescheider dann abgeschaltet wird, wenn die Materialschicht vor dem Magnetbandabscheider (7) das Abstandsmaß zwischen dem Förderband (6) der Förder- und Ausgabeeinrichtung und dem Magnetbandabscheider (7) überschreitet.This object is achieved in that, viewed in the conveying direction (X) of the conveying and dispensing device, a switching element (switch 12) is arranged in front of the magnetic tape separator (7) or at its inlet edge, via which the conveying and dispensing device and the magnetic tape separator are then switched off when the material layer in front of the magnetic belt separator (7) exceeds the distance between the conveyor belt (6) of the conveying and dispensing device and the magnetic belt separator (7).

Mit anderen als im Anspruch 1 gebrauchten Worten besteht der Kern der vorliegenden Erfindung darin, vor dem Magnetbandabscheider einen Schalter anzubringen, der dann, wenn beispielsweise ein zu großes Schrottknäuel vor dem Magnetbandabscheider auftaucht, das Förderband und den Magnetbandabescheider abschaltet, damit dann das Knäuel manuell entfernt werden kann.In other words, as used in claim 1, the essence of the present invention is to provide a switch in front of the magnetic tape separator, which switches off the conveyor belt and the magnetic tape separator when, for example, a too large ball of scrap appears in front of the magnetic tape separator, so that the ball is then removed manually can be.

Der Schalter selbst kann dabei als über einen Schwenkwinkel betätigtes Schaltelement (Anspruch 2) oder als Höhenabtaster (Anspruch 3) ausgebildet sein. Selbstverständlich sind auch andere Ausführungsbeispiel möglich, wie zum Beispiel ein Drucksensor oder dergleichen am Magnetbandabscheider selbst.The switch itself can be designed as a switching element actuated via a swivel angle (claim 2) or as a height scanner (claim 3). Of course, other exemplary embodiments are also possible, such as a pressure sensor or the like on the magnetic tape separator itself.

Die Erfindung wird im folgenden anhand der Zeichnung näher erläutert. Diese zeigt in

  • eine Prinzipdarstellung einer kompletten Brechanlage.
The invention is explained below with reference to the drawing. This shows in
  • a schematic diagram of a complete crushing plant.

Das zu zerkleinernde Material wird über einen ersten Aufgabetrichter 1 einem Vibrationssieb 2 zugeführt, das Grobmaterial und Vorsiebmaterial trennt. Das Grobmaterial wird einer Prallmühle 3 zugeführt, die das Material zerkleinert und über einen zweiten Aufgabetrichter 4 an einen - durchscheinend dargestellten - Zuführkanal 5 übergibt, dessen Unterseite durch das Fördermaterial 6 einer Förder- und Zuführeinrichtung gebildet ist. Über dieses Förderband 6 wird das zerkleinerte Material ausgetragen.The material to be shredded is fed via a first feed hopper 1 to a vibrating screen 2, which separates coarse material and pre-screen material. The coarse material is fed to an impact mill 3, which crushes the material and transfers it via a second feed hopper 4 to a feed channel 5 - shown through - the underside of which is formed by the conveying material 6 of a conveying and feeding device. The shredded material is discharged via this conveyor belt 6.

Etwa in der Mitte der Förderstrecke auf dem Förderband 6 liegt diesem im Abstand X ein Magnetbandabscheider 7 gegenüber, der etwaige magnetische Bestandteile des Förderguts aushebt und letztlich aussondert.Approximately in the middle of the conveyor section on the conveyor belt 6, at a distance X, there is a magnetic tape separator 7, which lifts out and ultimately separates out any magnetic components of the conveyed material.

Würde nun - wie in der Zeichnung schematische angedeutet - auf der Geröll- beziehungsweise Gesteinsschicht 8 ein größerer Schrottknäuel 9 mitgeführt, so würde dieser am Magnetbandabscheider 7 anstoßen und gegebenenfalls unter diesen hindurchgeschleppt und hindurchgepreßt werden. Dabei würden sowohl der Magnetbandabscheider 7 als auch das Förderband 6 gegebenenfalls stark in Mitleidenschaft gezogen.If - as indicated schematically in the drawing - a larger ball of scrap 9 were carried along on the scree or rock layer 8, this would knock against the magnetic tape separator 7 and, if necessary, be towed under it and pressed through it. Both the magnetic tape separator 7 and the conveyor belt 6 would be severely affected.

Um dies á priori zu verhindern, ist eine Art NOTABSCHALTUNG integriert, die sicherstellen soll, daß der Antrieb des Förderbands 6 abgeschaltet wird, wenn sich ein zu großer Metallknäuel oder auch eine zu dicke Materialschicht dem Magnetbandabscheider 7 nähert.To prevent this a priori, a kind of EMERGENCY SHUTDOWN is integrated, which is to ensure that the Drive of the conveyor belt 6 is switched off when a too large metal ball or too thick a material layer approaches the magnetic tape separator 7.

Diese Notabschaltung wird durch einen schwenkbeweglich (vergleiche 10) gelagerten Hebel 11 realisiert, der dann einen Schalter 12 betätigt, wenn er um einen dem Abstand X konjugierten Schwenkwinkel verschwenkt wird. (vergleiche Wirklinie B).This emergency shutdown is realized by a pivotably mounted lever 11 (see FIG. 10) which actuates a switch 12 when it is pivoted by a pivoting angle conjugate to the distance X. (compare line of action B).

Die Neuerung kann andererseits auch mit Hilfe eines Sensors als Höhenabtaster oder gegebenenfalls auch als Drucksensor am Magnetbandabscheider 7 realisiert sein. Wichtig ist, vor dem Magnetbandabscheider ein Schaltelement zu integrieren, über welches das Förderband 6 sicher stillgesetzt werden kann, wenn ein zu großes Teil zum Magnetbandabscheider 7 hin transportiert wird.On the other hand, the innovation can also be implemented with the aid of a sensor as a height scanner or, if appropriate, also as a pressure sensor on the magnetic tape separator 7. It is important to integrate a switching element in front of the magnetic tape separator, by means of which the conveyor belt 6 can be stopped safely if an excessively large part is transported to the magnetic tape separator 7.

Die Abschaltung selbst ist in der Zeichnung nur schematisch durch eine Wirklinie A zwischen einer mit dem Schalter 12 verbundenen Stromversorgung 13 und dem Antriebsmotor 14 für das Förderband 6 angedeutet.The shutdown itself is indicated only schematically in the drawing by an action line A between a power supply 13 connected to the switch 12 and the drive motor 14 for the conveyor belt 6.
