Schmelzkocher für thermoplastisches StraßenmarkierungsmaterialMelt cooker for thermoplastic road marking material

Thermoplastisches Straßenmarkierungsmaterial wird entsprechend öera Markierverfahren auf 150 bis 250 C aufgeheizt und dadurch verflüssigt . Dieses geschieht in gas- oder ölbeheizten wannenförmigen Behältern. Bewehrt sind indirekte Beheizungen, bei denen Wärmetrageröl aufgeheizt wird, welches seine 1Ve rme danach an die Behälterwandung abgibt . Zur /ergröSerung der Wärme-Cbertragungsflache kann die Hohlwelle des eingebauten Rührwerks mit Wär™eträgeröl von innen beheizt werden.Thermoplastic road marking material is heated to 150 to 250°C according to the marking process and thereby liquefied. This takes place in gas- or oil-heated tub-shaped containers. Indirect heating is recommended, in which heat transfer oil is heated and then releases its heat to the container wall. To increase the heat transfer surface, the hollow shaft of the built-in agitator can be heated from the inside with heat transfer oil.

In Bestreben die .Aufheizzeit zu verkürzen wird in c ;r eigenen Anmeldung G 88 00 4-54.f. ein Schmelzkocher vorgeschlagen, bei dem durch eine beheizte Förderschnecke eine wesentliche Vergrößerung der V/ärmeübertragungsf lache erreicht werden kann. Das Material wird im Durchlaufverfahren erwärmt und gleich dem Markierungsgerät zugeführt.In an effort to shorten the heating-up time, a melt cooker is proposed in our own application G 88 00 4-54.f., in which a heated conveyor screw can be used to significantly increase the heat transfer surface. The material is heated in a continuous process and fed directly to the marking device.

Für viele Anwender ist jedoch ein Echmelzkocher vorteilhafter, in dem das Material schnell erwärmt wird, danach darin verbleibt und in erwünschter '!enge abgefüllt wird. Fir diese Kocherart wird nachstehend eine Möglichkeit aufgezeigt, die "Värmeübertrafrvnesflache zu vergrößern.However, many users find it more advantageous to use a melt cooker in which the material is heated quickly, then left in the cooker and filled to the desired density. For this type of cooker, a possibility of increasing the heat transfer surface is shown below.

Beiliegende Zeichnung zeigt einen Schnelzkocher mit einer isolierten Außenwand(1), einem mit Vernetrageröl durchflossenem Zwischenraum^) und dem MaterialbehälterO). Erfindungsgemäß ist ein trommeiförmiger Einsatz(4) vorgesehen, der aus einem doppelwandigen Rohr besteht, welches von Warneträgerol durchströmt wird. Der Einsetzt; kann feet eingeschweißt sein, oder montierbar, zweckmäßig vom Boden her über Rohrstützen(5)» die gleichzeitig die Zuführung für das V/p'rmeträeeröl bilden. Leitbleche im Einsatz(4) eorgen für eine gleichmäßige Durchströmung. Das aufzuheizende Markierungsmaterial sollte zweck» guttr Wärmeaufnahme fliePen. Erreicht wird dies durch ein Rührwerk, v/elchee acE einer inixenschnecke(6) besteht, die eich im Einsatz(4) dreht und einer Außenschneckef?) mit entgegengesetzter ".'indungsrichtung zwischen Einset2(4) und Wand des fTaterielbehältere(3;· Beide Schnecken werden gemeinsam von der Rührwelle(8) bzw. vom Getriebe(9) und dem Rührwerkemotor(IO) angetrieben.The accompanying drawing shows a melt cooker with an insulated outer wall (1), an intermediate space (2) through which carrier oil flows, and the material container (3). According to the invention, a drum-shaped insert (4) is provided which consists of a double-walled pipe through which carrier oil flows. The insert can be welded in or mounted, preferably from the floor via pipe supports (5) which simultaneously form the supply for the carrier oil. Baffles in the insert (4) ensure a uniform flow. The marking material to be heated should flow in such a way that it absorbs heat well. This is achieved by an agitator consisting of an inner screw (6) which rotates in the insert (4) and an outer screw (6) with opposite direction of rotation between the insert (4) and the wall of the material container (3). Both screws are driven jointly by the agitator shaft (8) or by the gear (9) and the agitator motor (10).

Drehdurchführungen bekannter Art ist 28 möglich, in die Rührwelle(8) und damit euch in Tn/ienschreckeCe) und Außenechnekke(7) V/iirmeträperöl einzuspeisen. Zu diesem Zweck müssen Letztere hohl, also aus Rohr oder verschweißten Blechteilen hergestellt sein.Using rotary unions of known type, it is possible to feed hydraulic oil into the agitator shaft (8) and thus into the cylinder head (Ce) and external camshaft (7). For this purpose, the latter must be hollow, i.e. made from pipe or welded sheet metal parts.

Der Schmelzkocher kann entgegen der gezeichneten vertikalen Ausführung auch mit horizontaler Achse gefettigt werden. Eine eorgfältige Abdichtung der Rvhrwelle ist hierzu erforderlich.In contrast to the vertical version shown, the melting cooker can also be greased with a horizontal axis. Careful sealing of the stirring shaft is required for this.
