Description

KAISERLICHESIMPERIAL

PATENTAMT..PATENT OFFICE ..

Wenn bei Kammerapparaten, die zum Wärmeaustausch dienen, sehr dünne Platten zur Anwendung kommen, welche die Kammern von einander trennen, so entstehen hinsichtlich der Versteifung dieser Platten, als auch hinsichtlich der Abdichtung derselben mittels zwischenliegender Rahmen Schwierigkeiten, denen wir in unseren bisherigen Patenten zu begegnen trachteten.If in chamber devices that are used for heat exchange, very thin plates come into use, which separate the chambers from each other, so arise with regard to the stiffening of these panels, as well as with regard to the sealing of the same means intermediate framework difficulties that we face in our previous patents sought to meet.

Bei Verwendung der mit elastischen, gummihaltigen Stoffen überzogenen Eisenrahmen zur Bearbeitung gerbstoffhaltiger Laugen ergab sich, dafs bei der geringsten Verletzung des Dichtungsmaterials die Lauge mit dem Eisen in Berührung kam und dadurch tiefschwarz wurde. Auch rostete das Eisen und das Dichtungsmaterial verlor seinen Halt darauf. Man verlangte deshalb Ersatz des Eisens durch Kupfereinlage. Die Versuche mit Kupfer und mit Messing ergaben, dafs die Rahmen einestheils bei der Dünne des Materials zu wenig Stabilität besitzen, anderentheils dafs das im Gummi noch stets verbleibende Vulcanisationsniittel auf das anliegende Kupfer einwirkt. Zwischen diesem und dem aufgeklebten Gummi entsteht eine Schicht pulverförmig lockeren Schwefelkupfers, welches den Zusammenhang der beiden aufhebt und die dünne Gummischicht unelastisch macht. Es mufste also die Gummischicht dicker gemacht und von dem Rahmen mechanisch gehalten werden können. Das bisher in ähnlichen Fällen eingeschlagene Verfahren, Rahmen zu giefsen, dieselben abzudrehen und eine Nuth herauszuarbeiten, erfordert zu viel des theuren Metalles, ist eine schwierige und viel zu theure Arbeit und läfst sich vor allem auch nicht auf so dünne Rahmen anwenden, wie sie zur rationellen Leistung der Apparate nothwendig sind; die Schichten der Wärme austauschenden Medien werden zu dick.When using the iron frames covered with elastic, rubber-based materials for Processing of alkaline solutions containing tannin resulted in the slightest damage to the sealing material the lye came into contact with the iron and thereby became deep black. The iron and the sealing material also rusted lost his grip on it. It was therefore demanded to replace the iron with a copper insert. The experiments with copper and with brass showed that the frames were on the one hand have too little stability due to the thinness of the material; Rubber still remaining vulcanization agent acts on the adjacent copper. Between this and the glued-on rubber, a layer of loose powdery material is created Sulfur copper, which breaks the connection between the two and the thin rubber layer makes inelastic. So the rubber layer had to be made thicker and from that Frame can be held mechanically. The one that has been used in similar cases so far Method of casting frames, turning them off and working out a groove, requires too much of the expensive metal is a difficult and much too expensive work and runs Above all, they do not apply to frames as thin as they are for rational performance the apparatus are necessary; the layers of heat exchanging media become too thick.

Es kommt nun nach vorliegender Neuerung eine Versteifungs- und Abdichtungseinrichtung zur Ausführung, durch welche einerseits' den sehr dünnen, oft nur 0,7 mm starken Platten, welche z. B. bei den in der Bierbrauerei verwendeten Gegenstromkammerapparaten Anwendung finden, die täglich zur Reinigung geöffnet werden müssen, eine Randversteifung in dem geeigneten Material gegen Verbiegung oder Verstauchung ertheilt wird, während gleichzeitig diese Versteifung die geeignete Form zur Aufnahme des Dichtungsmaterials bietet.According to the present innovation, there is now a stiffening and sealing device for the execution, through which on the one hand 'the very thin, often only 0.7 mm thick panels, which z. B. in the counterflow chamber devices used in the brewery application that have to be opened daily for cleaning find edge stiffening in the appropriate material to prevent bending or sprain, while at the same time this stiffening is appropriate Form for receiving the sealing material offers.

Es werden zu diesem Zwecke' Leisten a, Fig. i, aus Kupfer, Messing oder anderem geeigneten Material durch Walzen oder Ziehen in flacher U-Form hergestellt, wobei die Innenseitenkanten der U-Form unterschneiden, so dafs die Form eine schwalbenschwanzförmige Nuth bildet. Aus diesen Leisten α werden die Rahmen b, Fig. 4, gebogen oder zusammengestofsen und an den Stöfsen zusammengelöthet oder genietet und bedarf ein solcher Rahmen keinerlei weiterer Bearbeitung.For this purpose, strips a, Fig. 1, made of copper, brass or other suitable material are produced by rolling or drawing in a flat U-shape, the inner side edges of the U-shape undercutting so that the shape forms a dovetail-shaped groove. The frames b, Fig. 4, are bent or joined together from these strips α and soldered or riveted together at the joints and such a frame does not require any further processing.

Ein solcher Rahmen wird nun auf der einen Seite der Platte c mit · seiner flachen Seite am Plattenrande oder in der Nähe des Plattenrandes aufgelöthet oder eventuell unter Zwischenfügung einer dünnen Dichtungsschicht aufgenietet und bildet durch seine U-Form eine feste Versteifung der Platte c gegen VerbiegungSuch a frame is now soldered on one side of the plate c with its flat side at the edge of the plate or in the vicinity of the edge of the plate or possibly riveted with a thin sealing layer in between and, through its U-shape, forms a firm stiffening of the plate c against bending

oder Verstauchung, während die Nuth die Aufnahme des Dichtungsmaterials d gestattet, welches nicht mehr in so dünnen Dimensionen wie bei Rahmenüberzügen gewählt zu werden braucht, da es- theilweise in der Versteifungsleiste α versenkt liegt. or sprain, while the groove allows the sealing material d to be accommodated, which no longer needs to be chosen in such thin dimensions as with frame covers, since it is partly sunk into the stiffening strip α .

Um diejenigen Ecken der Platte, an denen sich zur Kanalbildung Durchbrechungen e befinden, können solche Leistentheile α auf der Platte befestigt werden, welche ebenfalls Dichtungsmaterial d tragen und zwischen denen das Fluidum in die Kammer ein- oder aus derselben austreten kann.Around those corners of the plate at which there are openings e for the formation of channels, such strip parts α can be fastened on the plate, which likewise carry sealing material d and between which the fluid can enter or exit the chamber.

Zur Unterstützung der innerhalb des Rahmens liegenden Plattenfläche gegen inneren Druck können beliebige Lenkleisten f angeordnet sein. Es wird durch die beschriebene Ausführung. ein Mittel geschaffen, welches bei Kammerapparaten mit sehr dünnen Platten unter Verwendung möglichst geringen Materialbedarfs und geringer Dicke die erforderliche gröfste Stabilität des Rahmens und der Platte und zugleich einen mechanischen Halt des Dichtungsmaterials abgiebt.To support the plate surface lying inside the frame against internal pressure, any desired guide bars f can be arranged. It is carried out by the design described. A means is created which, in the case of chamber apparatus with very thin plates, uses the smallest possible material requirement and thinness, gives the required maximum stability of the frame and the plate and at the same time provides a mechanical hold for the sealing material.
