Abstract

Um Nachteile durch temperaturbedingte Vereisungen zu vermeiden, weist die Leiste (2) über die durch das Förderband (1) vorgegebene Breite eine verschließbare Ausnehmung (10) auf, in der mindestens eine selbstregulierende Parallel-Heizleitung (8) bekannter Bauart verlegt ist.Conveyor belt scrapers consist essentially of a directed vertically from below against the conveyor belt and extending across the width of the conveyor belt strip which is provided at the upper end with a belt cleaning the carbide and releasably connected by means of a screw with a arranged between the support frame holder. In order to avoid disadvantages due to temperature-induced icing, the strip (2) has a closable recess (10) over the width predetermined by the conveyor belt (1), in which at least one self-regulating parallel heating line (8) of known type is laid.
Description
Die Erfindung betrifft einen Förderbandabstreifer, der im wesentlichen aus einer von unten senkrecht gegen das Förderband gerichteten und über die Breite des Förderbandes verlaufenden Leiste besteht, die am oberen Ende mit einer das Förderband reinigenden Hartmetallleiste versehen und mittels einer Schraubverbindung mit einer zwischen dem Traggerüst angeordneten Halterung lösbar verbunden ist.The invention relates to a Förderbandabstreifer, which consists essentially of a vertically directed from below against the conveyor belt and extending across the width of the conveyor strip, which provided at the upper end with a belt cleaning the carbide and by means of a screw with a support arranged between the support bracket is detachably connected.
Förderbandabstreifer dieser Gattung funktionieren unter Hinweis auf den entsprechenden Verschleiß bei den üblichen, beispielsweise in Deutschland herrschenden Sommertemperaturen. Wenn jedoch die Temperaturen weit unter den Gefrierpunkt fallen, und bei entsprechenden Stillstandszeiten von Gurtbandanlagen Vereisungen und Festfrieren von Gegenständen am Gurtband festgestellt werden, treten unvermeidbar Zerstörungen am Gurtband und Abstreifereinrichtungen auf.Conveyor belt scrapers of this type work with reference to the corresponding wear in the usual, for example in Germany prevailing summer temperatures. However, if the temperatures fall well below freezing, and icing and freezing of objects on the webbing are detected with appropriate downtime of webbing systems, inevitable damage to the webbing and wiper devices on.
Um derartige Nachteile zu vermeiden, hat man versucht, so genannte Einschraubheizkörper in die Traversen von Abstreifereinrichtungen einzubringen. Derartige Einschraubheizkörper sind mit über die Länge der Traversen versehenen Rohrheizkörpern ausgestattet. Die Einschraubheizkörper sind mit einem Stromanschluss versehen und sind von außen über einen Reglerknopf auf eine der Witterung angepaßte Temperatur einzustellen. Da sie unterhalb des eigentlichen Abstreifers in der Traverse, also entfernt von der benötigten Beheizung angeordnet sind, benötigen sie eine große Menge Strom. Sie sind in der Bauweise technisch aufwendig, von den Kosten her teuer und da ein wesentlicher Teil außerhalb der Traverse angeordnet ist, sind sie gegenüber Umwelteinflüssen sehr empfindlich.In order to avoid such disadvantages, attempts have been made to introduce so-called screw-in heating elements in the traverses of wiper devices. Such screw-in heaters are equipped with provided over the length of the trusses tubular heaters. The screw-in radiators are provided with a power connection and must be set externally via a regulator knob to a temperature adapted to the weather. Since they are located below the actual scraper in the Traverse, so away from the required heating, they need a large amount of electricity. They are technically complex in construction, expensive in terms of their cost and since a substantial part is arranged outside the traverse, they are very sensitive to environmental influences.

Demgegenüber hat sich die Erfindung die Aufgabe gestellt, einen Förderbandabstreifer zu schaffen, dessen Funktionsfähigkeit bei entsprechenden Temperaturverhältnissen dahingehend sichergestellt wird, dass die Beheizung eine konstruktiv einfache und äußerst wirtschaftliche Lösung darstellt.In contrast, the invention has set itself the task of creating a conveyor belt scraper whose operability is ensured at appropriate temperature conditions to the effect that the heating is a structurally simple and extremely economical solution.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass die Leiste über die durch das Förderband vorgegebene Breite eine durch die Halterung luft- und wasserdicht mittels der Schraubverbindung verschließbare Ausnehmung aufweist, in der mindestens eine selbstregulierende Parallel-Heizleitung bekannter Bauart verlegt ist.This object is achieved in that the bar on the predetermined by the conveyor belt width air-tight by the holder and has a sealable by means of the screw recess, in which at least one self-regulating parallel heating line of known type is laid.
Die verwendeten selbstregulierenden Heizleitungen bestehen aus zwei parallelen Versorgungsleitern, die in ein vernetztes und mit Kohlenstoffteilchen dotiertes Kunststoff-Heizelement eingebettet sind. Steigt die Temperatur im Betrieb, so dehnt sich der Kunststoff durch molekulare Expansion aus, und die Abstände zwischen den Kohlenstoffteilchen vergrößern sich. Der Widerstand steigt und die Leistung sinkt. Bei Abkühlung kehrt sich dieser Prozess um und die Leistung steigt.The self-regulating heating cables used consist of two parallel supply conductors, which are embedded in a crosslinked and with carbon particles doped plastic heating element. As the temperature rises during operation, the plastic expands through molecular expansion and the distances between the carbon particles increase. The resistance increases and the performance drops. When cooled, this process reverses and performance increases.
Die Heizleitungen sind kunstoffummantelt und in der vorgesehenen Ausnehmung luft- und wasserdicht verschlossen angeordnet. Ein besonderer Vorteil der Erfindung ist darin zu sehen, dass je nach benötigter Leistung und entsprechender Größe der Ausnehmung mehr als eine selbstregulierende Parallel-Heizleitung angeordnet werden kann. Um Temperaturverluste bei der Beheizung zu vermeiden, sind die Heizleitungen dicht an der Innenwand der Ausnehmung verlegt und der übrige Hohlraum ist z. B. mit Silikon, Polyurethanschaum oder Ähnlichem ausgefüllt. Die so ausgeführte Beheizbarkeit ist in ihrer Lage äußerst günstig und effektiv angeordnet und benötigt in sehr wirtschaftlicher Ausführung nur einen sehr geringen Energieaufwand.The heating cables are plastic-coated and air-tight and sealed in the recess provided arranged. A particular advantage of the invention is the fact that more than one self-regulating parallel heating cable can be arranged depending on the required power and corresponding size of the recess. In order to avoid temperature losses during heating, the heating cables are laid close to the inner wall of the recess and the remaining cavity is z. B. filled with silicone, polyurethane foam or the like. The heatability performed in this way is extremely favorable and effectively arranged in its position and, in a very economical embodiment, requires only a very small amount of energy.
Im Rahmen der Erfindung sind verschiedene Ausführungsbeispiele vorstellbar, bei denen die allseits dicht verschlossene Ausnehmung unterhalb oder oberhalb der Schraubverbindungen oder auch in der die Leiste tragenden Halterung angeordnet sein kann.In the context of the invention, various embodiments are conceivable in which the mutually tightly closed recess can be arranged below or above the screw or in the holder carrying the bar.
Mehrere Ausführungsbeispiele der Erfindung sind in den Zeichnungen dargestellt und werden im nachfolgenden näher erläutert.Several embodiments of the invention are illustrated in the drawings and will be explained in more detail below.
