Description
Vorrichtung zur Behandlung von Flüssigkeit Die Erfindung betrifft eine Vorrichtung zur Behandlung von Flüssigkeit, insbesondere zur Verringerung von The invention relates to a device for treating liquid, in particular for reducing
Kesselsteinbildung an von Wasser durchströmten Rohren, mit einem einen Hohlraum einschließenden Gehäuse mit mittigen Anschlußöffnungen für die Rohrleitung, mit einer im Hohlraum mit allseitigen Abstand angeordnetenScale formation on pipes through which water flows, with a housing enclosing a cavity with central connection openings for the pipeline, with a spacing arranged in the cavity at all sides
Prallplatte, und mit einer ein Kraftfeld erzeugenden elektrischen Spule, die die Prallplatte konzentrisch umgibt,Baffle plate, and with an electric coil generating a force field, which concentrically surrounds the baffle plate,
Eine derartige Vorrichtung ist beispielsweise der AT- PS 379 358 zu entnehmen. Dabei wird von der Einwirkung eines magnetischen Kraftfeldes auf die zu behandelnde Flüssigkeit Gebrauch gemacht, wobei, um die Wirkung derartiger Vorrichtungen zu verstärken, die Flüssigkeit in turbulenter Strömung durch das Magnetfeld geführt wird. Gemäß der AT-PS 379 358 wird die magnetische Feldstärke durch eine Abstufung des Spaltes zwischen der Gehäuseinnenwand und der Prallplatte variiert. Es hat sich aber gezeigt, daß bei geringer Durchflußmen¬ ge trotz hoher magnetischer Feldstärke trotzdem nur ge¬ ringe Effekte erzielt wurden, da vermutet wird, daß die aus der ümlenkung durch die Prallplatte sich ergebenden Strömungsturbulenzen zu gering sein dürften.Such a device can be found, for example, in AT-PS 379 358. Use is made of the action of a magnetic force field on the liquid to be treated, the liquid being conducted through the magnetic field in a turbulent flow in order to enhance the effect of such devices. According to AT-PS 379 358, the magnetic field strength is varied by grading the gap between the housing inner wall and the baffle plate. It has been shown, however, that at low flow rates, despite the high magnetic field strength, only slight effects were nevertheless achieved, since it is assumed that the flow turbulence resulting from the deflection by the baffle plate should be too low.
Die Aufgabe der Erfindung besteht daher darin, die Wir¬ kung der eingangs genannten Vorrichtung zu verbessern, wobei dies gegebenenfalls auch bei verringerten Kraft¬ feldern möglich sein soll.The object of the invention is therefore to improve the effect of the device mentioned at the outset, this also possibly being possible with reduced force fields.
Erfindungsgemäß wird dies nun dadurch erreicht, daß im Strömungsweg der Flüssigkeit durch das Gehäuse zumindest ein Turbulenzen in der Flüssigkeit verstärkendes Element angeordnet ist.According to the invention, this is now achieved in that at least one turbulence in the liquid-reinforcing element is arranged in the flow path of the liquid through the housing.
Wie Versuche gezeigt haben, bewirkt jede Erhöhung der Turbulenzen in der Flüssigkeit innerhalb des magnetischen Kraftfeldes eine verbesserte Wirkung, bei Brauchwasser vor allem eine verringerte Kesselsteinbildung, wobei ein derartiges Element einerseits an verschiedenen Stellen innerhalb des Strömungsweges, andererseits aber auch mehrere Elemente, vor allem unterschiedlicher Art, vor¬ gesehen werden können. Die Art und Anzahl der Elemente richtet sich naturgemäß auch nach der Art der zu be¬ handelnden Flüssigkeit.As experiments have shown, every increase causes Turbulence in the liquid within the magnetic force field has an improved effect, in the case of process water, above all, a reduced scale formation, such an element being able to be seen on the one hand at different points within the flow path, but on the other hand also several elements, especially of different types. The type and number of elements naturally also depends on the type of liquid to be treated.
i einem ersten Ausführungsbeispiel kann als turbulenz¬ verstärkendes Element an zumindest einer Seite der Prallplatte ein konischer Körper mittig vorgesehen sein. Bevorzugt sind dabei beidseitig der Prallplatte ange¬ ordnete konische Körper miteinander verschraubt, wobei die Schraube vertieft angeordnet ist, und die Ver¬ tiefungen in den konischen Körpern ebenfalls turbulenz¬ verstärkend ausgebildet sind.In a first embodiment, a conical body can be provided in the center as a turbulence-reinforcing element on at least one side of the baffle plate. Conical bodies arranged on both sides of the baffle plate are preferably screwed to one another, the screw being arranged in a recessed manner and the depressions in the conical bodies likewise being designed to reinforce turbulence.
Geeignete konische Körper sind beispielsweise kegel - oder pyramidenstumpfförmig und mit ihrer größeren Grund- fläche an der Prallplatte so angeordnet, daß sie in die Anschlußöffnung ragen. Werden sie mit der kleineren Deckfläche an der Prallplatte anliegend fixiert, so bildet die in die Anschlußöffnung ragende größere Grund¬ fläche gegebenenfalls auch eine beschleunigende Durch- trittsdüse, wodurch die Wirkung ebenfalls verbessert werden kann.Suitable conical bodies are, for example, in the shape of a truncated cone or pyramid and, with their larger base area, are arranged on the baffle plate in such a way that they protrude into the connection opening. If they are fixed in contact with the baffle plate with the smaller cover surface, the larger base surface projecting into the connection opening may also form an accelerating passage nozzle, whereby the effect can also be improved.
Weitere Ausführungen können vorsehen, daß als turbulenz¬ verstärkendes Element' am Umfang der Prallplatte ins¬ besondere gekrümmte Zacken bzw. Zähne ausgebildet sind, sowie, daß als turbulenzverstärkendes Element in zu¬ mindest einer Seite der Prallplatte insbesondere ge¬ krümmte Nuten vorgesehen sind. Eine besonders inten¬ sive Durchwirbelung der Strömung wird dabei dadurch erzielt, daß die Krümmung der Zacken bzw. Zähne der Krümmung der Nuten entgegengesetzt ist.Further embodiments may provide that are formed as turbulenz¬ reinforcing member 'on the circumference of the baffle plate ins¬ special curved tines or teeth, and in that the turbulence-enhancing element in zu¬ least one side of the baffle plate in particular ge curved grooves are provided. A particularly intensive vortexing of the flow is achieved in that the curvature of the teeth or teeth of the Curvature of the grooves is opposite.
Die durch die umgelenkte, durchwirbelte Flüssigkeit in Schwingungen versetzte Prallplatte kann ihrerseits eben¬ falls zur Verbesserung der Wirkung beitragen, nämlich dadurch, daß ihre Schwingungen möglichst wenig gedämpft werden. Hiezu sieht eine weitere Ausführung vor, daß als turbulenzverstärkendes Element schwingungsfähige Distanzkörper für die Abstandhalterung der Prallplatte vorgesehen sind. Diese können beispielsweise durch Silikonschlauchstücke gebildet sein, die auf die Prall¬ platte durchsetzende Stifte aufgesteckt sind, und diese überragen. Weiters kann vorgesehen sein, daß als tur¬ bulenzverstärkendes Element zumindest in der Zuflu߬ öffnung ein Staukörper vorgesehen ist. Hier bietet sich eine bevorzugte Ausführungen in der Weise an, daß beide Anschlußöffnungen an Rohrstutzen ausgebildet sind, wo¬ bei der Staukörper im Rohrstutzen der Zuflußöffnung ge¬ halten ist.The baffle plate, which is caused to vibrate by the deflected, swirling liquid, can in turn also contribute to improving the effect, namely by damping its vibrations as little as possible. For this purpose, a further embodiment provides that vibrating spacers are provided as a turbulence-enhancing element for the spacing of the baffle plate. These can be formed, for example, by silicone tube pieces, which are pushed onto the pins passing through the baffle plate and protrude beyond them. Furthermore, it can be provided that a bluff body is provided as the turbulence-strengthening element, at least in the inflow opening. A preferred embodiment offers itself here in such a way that both connection openings are formed on pipe sockets, the bluff body being held in the pipe socket of the inlet opening.
Nachstehend wird nun die Erfindung an Hand der beiliegen- den Zeichnungen näher beschrieben, ohne darauf be¬ schränkt zu sein, wobei Fig. 1 einen Axialschnitt durch eine Einrichtung und Fig. 2 eine Innenansicht zeigt und eine Gehäusehälfte entfernt ist.The invention will now be described in more detail below with reference to the accompanying drawings, without being limited thereto, FIG. 1 showing an axial section through a device and FIG. 2 an interior view and one housing half removed.
Die Einrichtung ist mit einem durch zwei tellerartige, mittels Schrauben spiegelbildlich aneinandergesetzte Hälften 1,2 gebildeten Gehäuse versehen, in dem eine nur schematisch angedeutete ringförmige, elektrische Spule 9 vorgesehen ist. Diese umgibt eine in dem von den Hälften 1,2 eingeschlossenen Hohlraum 10 mit allseitigen Abstand angeordnete Prallplatte 13, sodaß die Prall¬ platte 13 in dem von der elektrischen Spule 9 erzeugten Kraftfeld liegt. Für die allseitige., für den Durchfluß der Flüssigkeit notwendige Distanzierung der Prallplatte 13 von der Gehäuseinnenseite, sorgen die Prallplatte 13 durchsetzende Stifte 14, deren Länge geringer als der Abstand zwischen den Hälften 1,2 an diesen Stellen ist, und auf die Stifte 14 mit überstand aufgeschobene Kappen oder Schlauchstücke 15 aus elastischem Material, bei- spiels.weise Silikon. Für die Zentrierung der Prallplatte 13 sorgen dabei nicht bezeichnete Abstufungen an den Innenflächen der Hälften 1,2 des Gehäuses. Der Hohl¬ raum 10 ist von der Spule 9 durch einen Kunststoffring 11 getrennt, der mittels seitlicher Dichtungsringe 12 gegen die beiden Hälften 1,2 elastisch angepreßt ist. Von den beiden Hälften 1,2 stehen mittig Rohrstutzen 3,4 ab, die zur Verbindung mit einer Rohrleitung vor¬ gesehen sind, und ein Außen- oder ein Innengewinde, eine Überwurfgewindemutter, Einrichtungen für eine Steckkuppelung usw. aufweisen können, und von denen der Rohrstutzen 3 die Zuflußöffnung 5 und der Rohrstutzen 4 die Abflußöffnung 6 umgibt bzw. darstellt. Turbulenzverstärkende Elemente innerhalb des Strömungs¬ weges sind mit den Bezugsziffern 7, 15, 16, 18, 19, 20 bezeichnet.The device is provided with a housing, which is formed by two plate-like halves 1, 2, which are mirror-inverted by screws, in which a ring-shaped electrical coil 9, which is only indicated schematically, is provided. This surrounds a baffle plate 13 which is arranged at all sides in the cavity 10 enclosed by the halves 1, 2, so that the baffle plate 13 lies in the force field generated by the electrical coil 9. The baffle plate 13 ensures the spacing of the baffle plate 13 from the inside of the housing, which is necessary for the flow of the liquid penetrating pins 14, the length of which is less than the distance between the halves 1, 2 at these points, and on the pins 14 with protruding caps or tube pieces 15 made of elastic material, for example silicone. Gradations on the inner surfaces of the halves 1, 2 of the housing, which are not designated, ensure the centering of the baffle plate 13. The cavity 10 is separated from the coil 9 by a plastic ring 11 which is elastically pressed against the two halves 1, 2 by means of lateral sealing rings 12. From the two halves 1, 2, there are pipe connections 3, 4 which are provided for connection to a pipeline and which can have an external or an internal thread, a union nut, devices for a plug coupling, etc., and of which the Pipe socket 3 surrounds or represents the inlet opening 5 and the pipe socket 4 the outlet opening 6. Turbulence-enhancing elements within the flow path are designated by the reference numerals 7, 15, 16, 18, 19, 20.
Ein erstes turbulenzverstärkendes Element ist in Form eines vor allem kegelsturapfförmigen Staukörpers 7 in der Zuflußöffnung 5, insbesondere im Rohrstutzen 3 ange¬ ordnet, in dem es durch Stege 8 von der Flüssigkeit umströmbar gehalten ist. Der Staukörper 7 bewirkt durch die Querschnittsverengung gleichzeitig auch eine Strömungsbeschleunigung. Durch die bereits erwähnten elastischen Kappen oder Schlauchstücke 15 wird die Schwingfähigkeit der Prallplatte 13 erhöht, sodaß auch diese damit indirekt zur besseren Durchwirbelung derA first turbulence-enhancing element is arranged in the form of a cone-shaped baffle 7, in particular in the inflow opening 5, in particular in the pipe socket 3, in which the liquid flows around it by means of webs 8. The bluff body 7 also causes a flow acceleration due to the narrowing of the cross section. Due to the already mentioned elastic caps or hose pieces 15, the vibrating ability of the baffle plate 13 is increased, so that this also indirectly for better swirling the

Deren Kopf ist einerseits in einem konischen Körper 16 versenkt, und das Schraubenende ist anderer¬ seits auch in der Bohrung des zweiten konischen Körpers 16 vertieft vorgesehen, sodaß beidseitig eine Vertiefung 18 verbleibt, die ebenfalls zur Erhöhung der Turbulenzen beitragen. Die konischen Körper 16 können an der Ober¬ fläche Unebenheiten, Rillen, Kanten usw. aufweisen. Der Rand der Prallplatte 13 ist mit Zacken oder Zähnen 19 bestückt, die gemäß Fig. 2 nach einer Seite gebogen sind. In den Seitenflächen der Prallplatte 13 sind wei¬ ters gekrümmte Nuten 20 (Fig. 2) vorgesehen, wobei die Krümmung der Nuten 20 der der Zacken bzw. Zähne 19 ent- gegengesetzt verläuft. Die Zacken bzw. Zähne 19 weisen eine Basisbreite und eine Höhe auf, die jeweils annähernd einem Zehntel des Radius der Prallplatte 13 entspricht. Die Breite der strahlenförmig ausgehenden Nuten 20 ent¬ spricht dabei annähernd ebenfalls diesem Wert. Contribute liquid in the magnetic field. Furthermore, conical bodies 16, in particular in the shape of a truncated cone, are fixed to the baffle plate 13 on both sides, an axial bore being provided, into which a connecting screw 17 is inserted. Its head is sunk in a conical body 16 on the one hand, and the screw end is in the bore of the second conical body 16 on the other hand Provided recessed so that a recess 18 remains on both sides, which also contribute to increasing the turbulence. The conical bodies 16 can have unevenness, grooves, edges etc. on the surface. The edge of the baffle plate 13 is equipped with teeth or teeth 19 which are bent to one side according to FIG. 2. Further curved grooves 20 (FIG. 2) are provided in the side surfaces of the baffle plate 13, the curvature of the grooves 20 running opposite to that of the teeth or teeth 19. The teeth or teeth 19 have a base width and a height, each of which corresponds approximately to one tenth of the radius of the baffle plate 13. The width of the radially extending grooves 20 corresponds approximately to this value.
