Description

Die Erfindung betrifft einen Doppelmantelspeicher für die Bereitung und Speicherung von warmem Brauchwasser gemäß Oberbegriff des Anspruches 1.The invention relates to a double jacket storage for the preparation and storage of hot industrial water according to the preamble of claim 1.

Derartige Doppelmantelspeicher sind allgemein bekannt und in Benutzung, so daß es diesbezüglich keines besonderen druckschriftlichen Nachweises bedarf. Der Anschluß der das Heizmedium führenden Vor- und Rücklaufanschlüsse an den Außenmantel ist insoweit problematisch, als das den Außenmantel nach oben anschließende ringförmige Außenmantelabschlußblech in Rücksicht auf möglichst kompakte Abmessungen des ganzen Speichers bei möglichst geringem Heizmediumsvolumen zwischen Speicherbehälter und Außenmantel eine geringe radiale Breite hat, die den dort an sich bequemen Anschluß der Vor- und Rücklaufanschlüsse nicht ohne weiteres zuläßt. Diese wurden deshalb mit entsprechenden 90°-Rohrbögen an entsprechende seitliche Öffnungen am Außenmantel angebracht, wobei die Bögen zudem ausreichend groß gehalten werden mußte, um einwandfreie Schweißnähte verlegen zu können. Dies führt also zu einer entsprechend großen seitlichen Raumbeanspruchung am Speicher. Zu berücksichtigen ist dabei ferner, daß aus Gründen möglichst geringer Fertigungskosten das ringförmige Außenmantelabschlußblech einer automatisch-maschinellen Verschweißung zugänglich bleiben muß.Double jacket stores of this type are generally known and in use, so that no special printed evidence is required in this regard. The connection of the supply and return connections leading the heating medium to the outer jacket is problematic insofar as the ring-shaped outer jacket end plate adjoining the outer jacket upwards has a small radial width in consideration of the most compact dimensions of the entire tank with the smallest possible heating medium volume between the storage tank and the outer jacket the convenient connection of the flow and return connections there does not allow. These were therefore attached to corresponding lateral openings on the outer jacket with corresponding 90 ° pipe elbows, the elbows also having to be kept large enough to be able to lay flawless weld seams. This therefore leads to a correspondingly large space requirement on the side of the accumulator. It should also be taken into account that, for reasons of the lowest possible production costs, the annular outer jacket end plate must remain accessible for automatic mechanical welding.

Der Erfindung liegt demgemäß die Aufgabe zugrunde einen Doppelmantelspeicher der eingangs genannten Art bezüglich des Anschlusses der Vor- und Rücklaufanschlüsse für das Heizmedium dahingehend auszubilden und zu verbessern, daß diese nach vollzogener maschineller Anschweißung des Außenmantelabschlußbleches mit minimaler seitlicher Raumbeanspruchung am Speicher und achsparallelen Abgang am Außenmantel angeschlossen werden können.The invention is therefore based on the object to design and improve a double jacket storage of the type mentioned with regard to the connection of the supply and return connections for the heating medium in such a way that after mechanical welding of the outer jacket end plate is carried out with minimal lateral space stress on the memory and axially parallel outlet on the outer jacket can be.

Diese Aufgabe ist für einen Doppelmantelspeicher der gattungsgemäßen Art nach der Erfindung durch die in den Kennzeichen des Anspruches 1 angeführten Merkmale gelöst. Vorteilhafte und praktische Ausgestaltungen ergeben sich nach den Unteransprüchen.This object is achieved for a double jacket memory of the generic type according to the invention by the features stated in the characterizing part of claim 1. Beneficial and practical configurations result from the subclaims.

Bei der erfindungsgemäßen Ausbildung nach Anspruch 1 in Verbindung mit Anspruch 2 werden zunächst einfach die Anschlußrohrstücke bodenseitig neben den Öffnungen am Außenmantel angeschweißt, und zwar bei achsparalleler Ausrichtung der Rohrstücke zur Speicherachse, d.h., die kleinen Flansche der Rohrstücke stehen senkrecht zum Außenmantel, wobei vorteilhaft deren anzuschweißender Randteil an die Wölbung des Außenmantels angepaßt ist. In den vom Flansch und dem Außenmantel gebildeten Zwickel werden nun die an die Zwickelform angepaßten und vorteilhaft durch Tiefziehen bzw. Pressen schalenartige Übergangsstücke eingesetzt, die damit die Öffnungen im Außenmantel abdecken und die nunmehr von außen längs ihrer Anschlußränder zu den Flanschen und zum Außenmantel verschweißt werden.In the embodiment according to the invention in accordance with claim 1 in conjunction with claim 2, the connecting pipe pieces are first simply welded on the bottom side next to the openings on the outer jacket, specifically with the pipe pieces aligned axially parallel to the storage axis, ie the small flanges of the pipe pieces are perpendicular to the outer jacket, advantageously their edge part to be welded is adapted to the curvature of the outer jacket. In the gusset formed by the flange and the outer jacket, the transition pieces adapted to the gusset shape and advantageously by deep drawing or pressing are now used, which thus cover the openings in the outer jacket and which are now welded from the outside along their connecting edges to the flanges and to the outer jacket .

Die Herstellung der Rohr- und der Übergangsstücke ist denkbar einfach, da, wie erwähnt, die Übergangsstücke aus entsprechend kleinen Blechzuschnitten einfach tiefgezogen werden können, weil beidseitig unterbrechungslos offene Formgebilde entstehen sollen. Die kleinen Flansche an den Rohrenden werden vorteilhaft durch Rollkröpfung angebracht und an beliebiger Stelle sekantial abgeschnitten, um einen entsprechend langen Anschlußrad zum Außenmantel entstehen zu lassen, der zweckmäßig schwach bogenförmig, der Wölbung des Außenmantels entsprechend, ausgebildet wird.The manufacture of the pipe and transition pieces is very simple, since, as mentioned, the transition pieces can be easily deep-drawn from correspondingly small sheet metal blanks, because open structures are to be created on both sides without interruption. The small flanges at the pipe ends are advantageously attached by roller cranking and cut secantially at any point in order to create a correspondingly long connecting wheel to the outer jacket, which is expediently slightly arcuate, corresponding to the curvature of the outer jacket.

Einen ähnlichen, genauso wenig Raum beanspruchenden Anschluß kann man gemäß Anspruch 1 in Verbindung mit Anspruch 6 auch dadurch erreichen, daß man einen entsprechend langen Teil des Rohrendes an einer Seite in Längsrichtung ausschneidet oder ebenflächig verformt und das Rohr damit am Außenmantel seitlich anlegt, wobei das dann an sich noch offene Ende des Rohres in geeigneter Weise verschlossen sein muß, was noch näher erläutert wird.A similar connection, which takes up just as little space, can also be achieved in accordance with claim 1 in conjunction with claim 6 by cutting out a correspondingly long part of the pipe end on one side in the longitudinal direction or deforming it flatly and thus placing the pipe laterally on the outer jacket, the then still open end of the tube must be closed in a suitable manner, which will be explained in more detail.

Sofern die Rücklaufabströmöffnung am anschlußfernen Boden des Außenmantels angeordnet und von da aus eine Rücklaufleitung außen am Außenmantel zur Anschlußseite des Speichers geführt ist, ist eine Ausbildung des eigentlichen Rücklaufanschlusses in der vorerwähnten Weise nicht erforderlich, sondern (auch dies wird noch näher erläutert) dafür wird das den eigentlichen Rücklaufanschluß bildende Rohrstück mit seinem Anschlußende so verformt, daß es in oder auf das obere Ende der Rücklaufleitung gesteckt und mit diesem verschweißt werden kann.If the return flow opening is arranged on the bottom of the outer jacket, which is remote from the connection, and from there a return line is led outside the outer jacket to the connection side of the storage tank, it is not necessary to form the actual return connection in the aforementioned manner, but (this will also be explained in more detail), this will be done the actual return connection forming pipe section deformed with its connection end so that it can be inserted into or onto the upper end of the return line and welded to it.

Der erfindungsgemäße Doppelmantelspeicher wird nachfolgend anhand der zeichnerischen Darstellung von Ausführungsbeispielen näher erläutert.The double jacket memory according to the invention is explained in more detail below with reference to the drawing of exemplary embodiments.

As can be seen from FIGS. 1, 2, the double jacket storage consists of a storage tank 1 provided with a cold water supply and hot water outlet connection 3, 4, which, with the exception of the tank bottom 5 provided with the connections 3, 4 a form-fitting outer jacket 2 guiding the heating medium is surrounded, on which heating medium supply and return connections 6, 7 are arranged directly next to the outer jacket end plate 8.

Beim praktischen Ausführungsbeispiel nach Fig. 1 bis 3 sind die Vor- und Rücklaufanschlüsse 6, 7 aus nach zwei Seiten unterbrechungslos offenen Übergangsstücken 9 sind und aus Anschlußrohrstücken 10 gebildet, wobei die Übergangsstücke 9 mit einer offenen Seite 11 auf den Umfangsrandbereich 13 von Öffnungen 14 im Außenmantel 2 aufgesetzt sind und deren rechtwinklig dazu orientierte andere offene Seite 12 mit einem Anschlußflansch 15 des jeweiligen Anschlußrohrstückes 10 verschlossen ist. Bezüglich der Form der Übergangsstücke 9 und insbesondere bezüglich deren nach zwei Seiten "unterbrechungslos offenen" Ausbildung wird auf Fig. 3 verwiesen, die diese Maßgabe klar verdeutlicht.In the practical embodiment according to FIGS. 1 to 3, the supply and return connections 6, 7 are made of transition pieces 9 which are open on two sides without interruption and are formed from connecting pipe pieces 10, the transition pieces 9 having an open side 11 on the peripheral edge region 13 of openings 14 in the Outer jacket 2 are placed and the other open side 12 oriented at right angles thereto is closed with a connecting flange 15 of the respective connecting pipe piece 10. With regard to the shape of the transition pieces 9 and in particular with regard to their "open without interruption" on two sides, reference is made to FIG. 3, which clearly illustrates this requirement.

Die einleitend bereits angedeuteten, bezüglich ihrer Fertigung und Fertigungsverarbeitung am Speicher vorteilhaften Weiterbildungen bestehen, wie ebenfalls aus den Fig. 1 bis 3 ersichtlich darin, daß die Übergangsstücke 9 als einstückige, tiefgezogene Preßteile ausgebildet sind, daß ferner die Anschlußflansche 15 der Anschlußrohrstücke 10 in Form von Rollkröpfungen der Rohrenden ausgebildet sind und daß schließlich die Anschlußflansche 15 anschlußseitig zum Außenmantel 2 mit an desse Wölbungsform angepaßten, sekantial orientierten Anschlußrändern 16 versehen sind. Fig. 1 macht deutlich, wie dicht die Vor- und Rücklaufanschlüsse 6, 7 am Außenmantel 2 angeordnet werden können, d.h., die Vor- und Rücklaufanschlüsse 6, 7 sind mit ihren zur Behälterlängsachse BA achsparallelen Längsachsen LA mit einer Distanz D zur Wand W des Außenmantels 2 angeordnet, die nur geringfügig größer ist als der halbe Durchmesser der Abgangsöffnungen der Anschlüsse 6, 7. Außerdem zeigt Fig. 1, wie das ringförmige Außenmantelabschlußblech 8 in der Regel ausgeformt und zwischen dem Boden 5 und dem Außenmantel 2 eingesetzt und verschweißt ist, d.h., es liegt kein glatt zylindrisch auslaufender Umfangsrand 17 vor. Ein solcher zylindrisch glatt auslaufender Rand 17 kann jedoch, wie Fig. 6 zeigt, durchaus ebenfalls problemlos hergestellt werden, wobei es dann ohne weiteres möglich ist, die Anschlüsse gemäß der Fig. 4, 5 und 7 auszubilden, d.h., hierbei sind die Vor- und Rücklaufanschlüsse 6, 7 aus Rohren 3', 4'gebildet, deren Anschlußenden einseitig an den Außenmantel 2 formangepaßt und mit einer Überströmöffnung 14' versehen an den Außenmantel 2 über dessen Überströmöffnung 14 angelegt und ringsum mit dem Außenmantel 2 verschweißt.The developments already indicated in the introduction, which are advantageous with regard to their manufacture and manufacturing processing at the storage device, as can also be seen from FIGS. 1 to 3, consist in the fact that the transition pieces 9 are designed as one-piece, deep-drawn pressed parts, that the connecting flanges 15 of the connecting pipe pieces 10 are in the form are formed by cranking of the pipe ends and that, finally, the connecting flanges 15 are provided on the connection side to the outer jacket 2 with secantially oriented connecting edges 16 adapted to the shape of the curvature. Fig. 1 shows how close the supply and return connections 6, 7 can be arranged on the outer jacket 2, that is, the supply and return connections 6, 7 are longitudinal axes LA parallel to the container longitudinal axis BA with a distance D to the wall W des Outer jacket 2 arranged, which is only slightly larger than half the diameter of the outlet openings of the connections 6, 7. In addition, Fig. 1 shows how the annular outer jacket end plate 8 is usually shaped and inserted and welded between the bottom 5 and the outer jacket 2, that is, there is no smoothly cylindrically tapering peripheral edge 17. Such a cylindrically smoothly running edge 17 can, however, as FIG. 6 shows 4, 5 and 7, that is, the supply and return connections 6, 7 are formed from tubes 3 ', 4', the connection ends of which are on one side form-adapted to the outer jacket 2 and provided with an overflow opening 14 ', applied to the outer jacket 2 via its overflow opening 14 and welded all around to the outer jacket 2.

Beim Ausführungsbeispiel nach Fig. 4 sind die Rohre 3', 4'an ihren Anschlußenden mit einem seitlichen Ausschnitt 18 versehen, und der Wandungslappen 19 des Anschlußendes ist zu einer Verschlußkappe 20 ausgebildet. Eine solche Form läßt sich mit entsprechend formangepaßten Preßwerkzeugen ohne weiteres herstellen. Ohne erst einen Ausschnitt 18 am Rohrende vornehmen zu müssen, kann aber dieses auch im Sinne der Fig. 5, 7 verformt werden, d.h., hierbei ist die Wandung der Rohre 3', 4' an deren Anschlußenden einseitig zu einer Anschlußfläche 21 und der andere Teil der Wandung zu einer Verschlußkappe 20 verformt ausgebildet, wobei hier in der Anschlußfläche 21 die Überströmöffnung 14' angebracht sein muß. Daß dabei zunächst ein Spalt 20' mit der etwa dargestellten Form offen bleibt, spielt keine Rolle, da das Ganze ja dann im aufgesetzten Zustand längs der strichpunktierten Linie mit dem Außenmantel 2 verschweißt wird.4, the tubes 3 ', 4' are provided with a lateral cutout 18 at their connecting ends, and the wall tab 19 of the connecting end is formed into a closure cap 20. Such a shape can be easily produced with correspondingly adapted press tools. Without having to make a cutout 18 at the end of the tube, this can also be deformed in the sense of FIGS. 5, 7, that is to say the wall of the tubes 3 ', 4' at one end thereof is one-sided to a connecting surface 21 and the other Part of the wall is deformed to form a closure cap 20, the overflow opening 14 ′ having to be provided in the connection surface 21 here. It does not matter that a gap 20 'with the shape shown is initially open, since the whole thing is then welded to the outer jacket 2 along the dash-dotted line.

Die Ausführungsform des Speichers nach Fig. 6, 8 zeigt eine andere Gestaltung des Rücklaufes RL, d.h., der Vorlaufanschluß 6 bedarf hier keiner weiteren Erläuterung, da dieser in der einen oder anderen Weise, wie vorbeschrieben, ausgebildet sein kann (Fig. 1, 4 oder 5). Was den Rücklauf RL betrifft, so ist dieser an einer Öffnung 22 des Außenmantelbodens 23 angesetzt und als Rücklaufleitung 24 außen am Außenmantel 2 zur Anschlußseite des Speichers geführt, in deren Ende 25 der entsprechend formangepaßte Rücklaufanschluß 7 gesteckt und verschweißt ist. Auch hierbei ergibt sich keine größere seitliche Raumbeanspruchung durch den Rücklaufanschluß 7. Beim Doppelmantelspeicher gemäß Fig. 6 handelt es sich im übrigen um einen für eine horizontale Anordnung, der lediglich aus Platzgründen in Senkrechtstellung dargestellt ist.The embodiment of the memory according to FIGS. 6, 8 shows a different design of the return RL, ie the flow connection 6 does not require any further explanation here, since it can be designed in one way or another as described above (FIGS. 1, 4 or 5). As for the return RL, it is attached to an opening 22 of the outer jacket base 23 and is guided as a return line 24 on the outside of the outer jacket 2 to the connection side of the accumulator, in the end 25 of which the correspondingly shaped return port 7 is inserted and welded. Here, too, there is no greater lateral space stress through the return connection 7. The double jacket storage unit according to FIG. 6 is, moreover, one for a horizontal one Arrangement that is shown in vertical position only for reasons of space.
