Description

Es ist bereits vorgeschlagen worden, die Außenwandung einer zur Zinkdestillierung dienenden Muffel mit längs verlaufenden, zahnförmigen Auskehlungen zu versehen.It has already been proposed that the outer wall of a zinc distillation unit to provide the serving muffle with longitudinal, tooth-shaped grooves.

Wie gefunden wurde, läßt sich die Wärmeübertragung und Standfestigkeit solcher Muffeln noch wesentlich steigern, wenn sowohl ihre Innen- als auch ihre Außenwandung wellen- oder nackenförmig ausgebildet wird.As has been found, the heat transfer and stability such grouches still increase considerably, if both their inner and hers Outer wall is formed wave-shaped or neck-shaped.

Da die Strömung der Heizgase entlang der Muffel laminar oder fast laminar verläuft, werden durch die wellenförmig oder gezackt ausgebildete Oberfläche in den Heizgasen Turbulenzen erzeugt, die das :Maximum der Wärmeübertragung erzielen lassen. Einfache Riefen reichen hierfür nicht aus; die Ausbildung der Oberfläche muß vielmehr den Strömungsverhältnissen im Destillierofen genau angepatit sein. Darüber hinaus wird durch die Profilierung auch der Innenwandung eine weitere Vergrößerung der Oberfläche, durch die die Wärme in die Muffel einströmt, erzielt.Because the flow of the heating gases along the muffle is laminar or almost laminar, are due to the wavy or jagged surface Generates turbulence in the hot gases, which: Achieve maximum heat transfer permit. Simple grooves are not sufficient for this; the formation of the surface Rather, it must be precisely matched to the flow conditions in the still. In addition, the profiling also increases the size of the inner wall the surface through which the heat flows into the muffle.

Die Erfindung ist in der Zeichnung an zwei Ausführungsbeispielen dargestellt. Fig. i ist eine Längsansicht einer Muffel; Fig. 2 ist ein Schnitt durch diese Muffel; Fig.3 ist die Längsansicht einer anderen Ausführungsform der 'Muffel; Fi.g. 4 ist ein Schnitt durch Fig. 3.The invention is shown in the drawing using two exemplary embodiments. Fig. I is a longitudinal view of a muffle; Fig. 2 is a section through this muffle; Fig. 3 is a longitudinal view of another embodiment of the 'muffle; Fi.g. 4 is a section through FIG. 3.

Die äußere und die innere Wandung der in Fig. i und 2 dargestellten Muffel verläuft, abgesehen von <lern Teil an der Grundfläche, wellenförmig.The outer and inner walls of the shown in Figs The muffle runs in a wave-like manner, with the exception of the lower part of the base.

Bei der in Fig. 3 und 4 dargestellten Muffel verlaufen die äußere und die innere Wandung gezackt.In the case of the muffle shown in FIGS. 3 and 4, the outer ones run and the inner wall jagged.
