Abstract

The support and guide rails and where applicable the side rails of the conveyor are coated with a layer of hard metal solder between 2 and 10 mm thickness. The solder pref. consists of high carbon chromium steel or materials according to DIN 8555 from alloy gp. 10. The heads of the scraper bolts of the conveyor can also have a similar coating. The conveyor is used to move anhydrite and reactive gypsum. USE/ADVANTAGE - Quieter running of trough chain conveyor esp. for hot abrasive materials.

Description

Die Erfindung betrifft Trogkettenförderer mit speziellen Führungs- und gegebenenfalls speziellen Seitenschienen sowie deren Verwendung.The invention relates to trough chain conveyors with special Guide and, if necessary, special side rails as well as their use.

Trogkettenförderer, vorzugsweise die Zweistrangketten­ ausführung, sind geeignet, Schüttgüter verschiedenster Konsistenz horizontal, fallend und steigend bis etwa 30°C Neigung zu fördern.Trough chain conveyor, preferably the two-strand chain design, are suitable for bulk goods of all kinds Consistency horizontal, falling and rising to about Promote 30 ° C inclination.

Derartige Trogkettenförderer, auch Redler genannt, sind hinlänglich aus der Literatur bekannt (Brockhaus Enzyklopädie, Elfter Band, Seite 649; Lueger, Lexikon der Technik, Band 15 (1971), Seite 217 bis 219, Deutsche Verlags-Anstalt GmbH Stuttgart; Schüttgutförderer, DJ Gest. Salzer, Kratzer- und Trog­ kettenförderer, Kap. 4 vo. Morrit Wäspi, Seite 95 bis 110, Krauskopf-Verlag 1968). Such trough chain conveyors, also called Redler, are well known from the literature (Brockhaus Encyclopedia, Eleventh Volume, page 649; Lueger, Lexikon der Technik, Volume 15 (1971), page 217 until 219, Deutsche Verlags-Anstalt GmbH Stuttgart; Bulk material conveyor, DJ gest. Salt, scratch and trough chain conveyor, chap. 4 vo. Morrit Wäspi, page 95 to 110, Krauskopf Verlag 1968).  

Der Einsatz der Trogkettenförderer hat sich auf vielen Gebieten, insbesondere beim Transport heißer abrasiver Medien (Schüttgüter), bewährt.The use of trough chain conveyors has changed on many Areas, especially when transporting hot abrasive Media (bulk goods), proven.

Nachteilig bei den Trogkettenförderern ist jedoch, daß bei ihrem Betrieb häufig hohe Lärmgeräusche (insbesonde­ re Quietschgeräusche) auftreten.A disadvantage of trough chain conveyors, however, is that Frequently high noise levels during their operation (in particular right squeaking noises) occur.

Aufgabe war es daher, Trogkettenförderer zur Verfügung zu stellen, bei denen während des Betriebes die Lärm­ emission gering ist, die aber gleichzeitig hohe Stand­ zeiten aufweisen.The task was therefore to provide trough chain conveyors to make noise during operation emission is low, but at the same time high level have times.

Die Aufgabe konnte nun mit einer speziellen Ausführungs­ form der an sich bekannten Trogkettenförderer gelöst werden.The task could now be carried out with a special execution form of the well-known trough chain conveyor solved become.

Gegenstand der Erfindung sind Trogkettenförderer, ins­ besondere Zweistrangtrogkettenförderer, mit auf Schienen laufenden bzw. gleitenden Ketten, die dadurch gekenn­ zeichnet sind, daß sie Trag- bzw. Führungsschienen und gegebenenfalls Seitenschienen mit Hartmetallauftrag­ schweißung in Form einer 2-10 mm dicken Schicht im Ober­ trum aufweisen.The invention relates to trough chain conveyors, ins special double-strand trough chain conveyor, with on rails running or sliding chains, which are characterized are characterized in that they support and guide rails and if necessary, side rails with hard metal application welding in the form of a 2-10 mm thick layer in the upper have strum.

Vorzugsweise besteht die Hartmetallauftragsschweißung aus einer Auftragsschweißung mit hoch gekohltem Chrom­ stahl oder Werkstoffen nach DIN 8555 aus der Legierungs­ gruppe 10.The hard metal cladding is preferably used from a build-up weld with high-carbon chrome steel or materials according to DIN 8555 from the alloy group 10.

Nach Auftragschweißung der Führungs- und/oder Seiten­ schienen des Trogkettenförderers mit hoch gekohltem Chromstahl (z. B. Vautid® der Firma Verschleißtechnik - Dr. Ing. H. Wahl GmbH & Co, Stuttgart-Ruit) konnte die Lärmemission beträchtlich vermindert werden.After welding the guide and / or sides rails of the trough chain conveyor with high carbon  Chrome steel (e.g. Vautid® from Wear Technology - Dr. H. Wahl GmbH & Co, Stuttgart-Ruit) was able to Noise emissions can be significantly reduced.

Die verringerte Lärmemission ist wahrscheinlich auf die besondere Struktur der Hartmetallauftragschweißung, näm­ lich die hohe Rißauffälligkeit des Werkstoffes, zurück­ zuführen.The reduced noise emission is likely due to that special structure of hard metal surfacing, näm Lich the high level of cracking of the material back respectively.

Besonders bevorzugt weisen die Köpfe der Kratzerbolzen der Trogkettenförderer ebenfalls eine Hartmetallauf­ tragschweißung auf.The heads of the scraper pins particularly preferably point the trough chain conveyor also has a carbide support weld on.

Die Kettenglieder der Ketten haben bevorzugt Achsabstän­ de von ca. 200 bis 300 mm und sind mit Kettenbolzen mit­ einander verbunden. Etwa jeder 10. bis 20. Kettenbelzen hat einen erhöhten Bolzenkopf (Kratzerbolzen), mit dem anhaftendes Produkt aufgelockert bzw. abgekratzt werden kann.The chain links of the chains preferably have center distances de from approx. 200 to 300 mm and are with chain bolts connected to each other. About every 10th to 20th chain covering has a raised pin head (scraper pin) with which adhering product can be loosened or scraped off can.

Ein weiterer Gegenstand der Erfindung ist ein Verfahren zur Herstellung von Trogkettenförderern mit auf Füh­ rungs- und gegebenenfalls Seitenschienen gleitenden Ket­ ten mit Hartmetallauftragschweißung, welches dadurch ge­ kennzeichnet ist, daß auf die Führungs-, gegebenenfalls auf die Seitenschienen und gegebenenfalls auf die Köpfe der Kratzerbolzen Werkstoffe nach DIN 8555 aus der Le­ gierungsgruppe 10, insbesondere hoch gekohlte Chromstäh­ le, aufgeschweißt werden.Another object of the invention is a method for the production of trough chain conveyors Ket sliding and possibly side rails with hard metal overlay welding, which is characterized in that on the leadership, if necessary on the side rails and possibly on the heads the scratch pin materials according to DIN 8555 from Le Gierungsgruppe 10, especially high carbon chrome steel le, are welded on.

Die erfindungsgemäßen Trogkettenförderer werden insbe­ sondere zur Förderung von Anhydrit und Rea-Gips verwen­ det.The trough chain conveyor according to the invention are in particular especially used to promote anhydrite and gypsum det.
