Description

Drucksicherung der Plattenwärmeaustauscher, die aus ebenen Zwischenplatten und Kanalplatten bestehen Die Erfindung bezieht sich auf Platten von Wärmeaustauschern und hat den Zweck, eine größere Widerstandsfähigkeit der Platten gegen Formveränderungen infolge inneren Überdruckes der zu behandelnden Flüssigkeit herbeizuführen.Pressure protection of the plate heat exchanger, which consists of flat intermediate plates and channel plates. The invention relates to plates of heat exchangers and has the purpose of making the panels more resistant to changes in shape due to internal overpressure of the liquid to be treated.

Derartige Wärmeaustauscher bestehen aus einer mehr oder weniger großen Anzahl einzelner Platten verschiedener Form, und zwar unterscheidet man abwechselnd die Kanalplatten, die mit Nuten für die Gummiringe zum Abdichten versehen sind, und ebene Zwischenplatten, die keine Gumminuten haben. Die Platten werden zu Plattenpaketen vereinigt und durch Spindeln zusämmengepreßt.Such heat exchangers consist of a more or less large one Number of individual plates of different shapes, one differentiates alternately the channel plates, which are provided with grooves for the rubber rings for sealing, and flat intermediate plates that have no rubber minutes. The plates become plate packs united and pressed together by spindles.

Innerhalb der Kanalplatten entsteht von der Flüssigkeit her, die mittels Pumpen durch die Kanalplattenhohlräume hindurchgepreßt wird, ein mehr oder weniger starker Druck nach außen, der eine Formveränderung der Kanalplatten zur Folge hat. Die Kanalplatten dehnen sich dann seitlich aus, wodurch die Nute für den Gummiring sehr stark beansprucht wird, ferner der Gummiring leicht undicht und,die Kanalplatte leicht beschädigt wird.Inside the channel plates, the liquid arises, which by means of Pumps is pressed through the channel plate cavities, a more or less strong pressure to the outside, which changes the shape of the duct plates. The channel plates then expand laterally, creating the groove for the rubber ring is very heavily used, furthermore the rubber ring leaks slightly and, the channel plate easily damaged.

Diese Nachteile sollen durch die Erfindung beseitigt werden, und zwar dadurch, daß die ebenen Zwischenplatten mit verstärkten Rändern versehen sind, die die Ränder der Kanalplatten rahmenartig umgreifen. Der Rand der Kanalplatten liegt also beim zusammengebauten Apparat in einem widerstandsfähigen Rahmen, so daß ein seitliches Strecken und Ausdehnen der Kanalplatten nicht möglich ist. Dadurch behalten beim Zusammenschrauben der Platten die Gummiringnuten ihre Form, wodurch eine bessere Abdichtung erzielt wird.These disadvantages are to be eliminated by the invention, namely in that the flat intermediate plates are provided with reinforced edges that encompass the edges of the channel plates like a frame. The edge of the channel plates lies so with the assembled apparatus in a resistant frame, so that a lateral stretching and expansion of the duct plates is not possible. Keep this When screwing the panels together, the rubber ring grooves change their shape, creating a better one Sealing is achieved.

An Hand der Zeichnung sei die Erfindung in einem Ausführungsbeispiel näher erläutert. Es sind a die Kanalplatten mit den Kanälen b für die Flüssigkeit und Nuten c für die Gummiringe. Die Gummiringe zum Abdichten der Ränder sind mit d bezeichnet. e sind die ebenen Zwischenplatten, die mit einer Verstärkung f versehen sind, die eine aus: dem Blech gebogene Kante öder eine durch Schweißen, Nieten oder auf andere Art befestigte Leiste sein kann. Die Verstärkung f verhindert ein seitliches Ausweichen der Kanalplatten.The invention will be explained in more detail in an exemplary embodiment with reference to the drawing. There are a the channel plates with the channels b for the liquid and grooves c for the rubber rings. The rubber rings for sealing the edges are labeled d. e are the flat intermediate plates, which are provided with a reinforcement f, which can be an edge bent from the sheet metal or a strip fastened by welding, riveting or in some other way. The reinforcement f prevents the channel plates from giving way to the side.
