Magnetic lime converter
BeschreibungDescription
Die Erfindung betrifft einen magnetischen Kalkwandler zur Verhinderung und Beseitigung von Kalkablagerungen, Rost und Schmutz in Kühlwasserkreisläufen, in Brauchwasseranlagen und in Hauswasserinstallationen mit den Merkmalen des Oberbegriffs des Anspruchs 1.The invention relates to a magnetic lime converter for preventing and removing lime deposits, rust and dirt in cooling water circuits, in service water systems and in domestic water installations with the features of the preamble of claim 1.
Solche magnetischen Kalkwandler sind z.B. aus der DE-U-92 16 240 bekannt. Ebenso sind Wasserfilter bekannt. Es wurde auch versucht, beides zu kombinieren, indem ein separater Kalkwandler und ein separater Wasserfilter in Reihe geschaltet wurden.Such magnetic limescale converters are known, for example, from DE-U-92 16 240. Water filters are also known. Attempts have also been made to combine the two by connecting a separate limescale converter and a separate water filter in series.
Aufgabe der vorliegenden Erfindung ist es, eine platzsparende und leicht, z.B. bei der Reinigung, zu bedienende Kombination eines Kalkwandlers mit einem, Wasserfilter zu schaffen.The object of the present invention is to create a space-saving and easy-to-use combination of a limescale converter with a water filter, e.g. when cleaning.
Diese Aufgabe wird mit den im kennzeichnenden Teil des Anspruchs 1 genannten Merkmalen gelöst. Fortbildungen und vorteilhafte Ausführungen der Erfindung sind in den weiteren Ansprüchen umfaßt.This object is achieved with the features mentioned in the characterizing part of claim 1. Further developments and advantageous embodiments of the invention are included in the further claims.
Erfindungsgemäß ist der Magnet innerhalb eines Wasserfilters angeordnet und wird von dem bereits durch den Wasserfilter von Schmutzpartikeln gereinigten Wasser umspült.According to the invention, the magnet is arranged inside a water filter and is surrounded by water that has already been cleaned of dirt particles by the water filter.
Nach einer bevorzugten Ausführung der Erfindung ist der Magnet koaxial innerhalb eines Steigrohres angeordnet,According to a preferred embodiment of the invention, the magnet is arranged coaxially within a riser pipe,
welches in einem Abstand von einem zylindrischen Wasserfilter umgeben und mit dem Wasserfilter in einem Gehäuse angeordnet ist, wobei zwischen der Gehäuseinnenwand und dem Wasserfilter ein Zwischenraum vorhanden ist. Der Zulauf erfolgt in diesen Zwischenraum und der Ablauf aus dem Steigrohr.which is surrounded at a distance by a cylindrical water filter and is arranged in a housing with the water filter, with a gap between the inner wall of the housing and the water filter. The inflow is into this gap and the outflow from the riser pipe.
Der Zulauf und der Ablauf weisen vorteilhafterweise Anschlüsse auf und sind einer horizontalen Ebene angeordnet.The inlet and the outlet advantageously have connections and are arranged on a horizontal plane.
Der Magnet bestehet bei der bevorzugten Ausführung der Erfindung aus mehreren, jeweils durch ein Joch getrennten Einzelmagneten, die z.B. mit axialen Bohrungen auf einer Stange aufgereiht sind und ihrer Zahl entsprechend viele Magnetfelder entlang des so ausgebauten Stabmagneten bilden.In the preferred embodiment of the invention, the magnet consists of several individual magnets, each separated by a yoke, which are lined up on a rod with axial holes, for example, and form a number of magnetic fields corresponding to their number along the bar magnet thus constructed.
Das Gehäuse, der Wasserfilter, das Steigrohr und der Magnet sind, nach der bevorzugten Ausführung der Erfindung, direkt oder über Zwischenträger sich nach unten erstreckend, an einem Filterkopf angeordnet, der den Zulauf und den Ablauf aufweist.According to the preferred embodiment of the invention, the housing, the water filter, the riser pipe and the magnet are arranged directly or via intermediate supports extending downwards on a filter head which has the inlet and the outlet.
Nach einer besonderen Ausführung der Erfindung ist zwischen dem Steigrohr und dem Wasserfilter und/oder zwischen diesem und dem Gehäuse Aktivkohle oder ein Ionen-Austauscher-Granulat eingefüllt.According to a particular embodiment of the invention, activated carbon or ion exchange granules are filled between the riser pipe and the water filter and/or between the latter and the housing.
Der Zulauf und der Ablauf sind mit Manometern oder Druckaufnehmern mit elektronischer Auswertung versehen, damit eine Druck-, bzw. Druckdifferenzüberwachung erfolgen kann.The inlet and outlet are equipped with pressure gauges or pressure sensors with electronic evaluation, so that pressure or pressure difference monitoring can take place.
Der Filterkopf kann aus Metall, z.B. Messing, oder einem glasfaserverstärkten Kunststoff bestehen. DasThe filter head can be made of metal, e.g. brass, or a glass fibre reinforced plastic. The
Gehäuse ist vorteilhafterweise aus transparentem und schlagfestem Kunststoff, z.B. Styren mit Acryl gefertigt. Der Wasserfilter besteht entweder aus einem selbsttragenden Kunststoff oder weist einen geeigneten Träger auf.The housing is preferably made of transparent and impact-resistant plastic, e.g. styrene with acrylic. The water filter is either made of a self-supporting plastic or has a suitable carrier.
Im folgenden wird die Erfindung anhand einer Zeichnung beispielhaft näher beschrieben.In the following, the invention is described in more detail with reference to a drawing.
Der magnetische Kalkwandler weist einen stabförmig aufgebauten Magneten auf, bei dem mehrere scheibenförmige Einzelmagneten 10 jeweils durch ein Joch 13 getrennt und mit axialen Bohrungen versehen auf einer Stange 10' aufgereiht sind, die in einem Filterkopf 3 verschraubt ist und sich von diesem Filterkopf 3 aus abwärts erstreckt. Der Filterkopf 3 ist ein flanschartiges Teil mit einer hohlzylindrischen Basis 3', an deren Kopf seitlich gegenüberliegend in gleicher Höhe Zulauf 1 und Ablauf 2 angeordnet sind.The magnetic lime converter has a rod-shaped magnet in which several disc-shaped individual magnets 10, each separated by a yoke 13 and provided with axial holes, are lined up on a rod 10', which is screwed into a filter head 3 and extends downwards from this filter head 3. The filter head 3 is a flange-like part with a hollow cylindrical base 3', on the head of which the inlet 1 and outlet 2 are arranged laterally opposite each other at the same height.
Zulauf 1 und Ablauf 2 weisen Kupplungen 4 für Anschlüsse auf. Die hohlzylindrische Basis 3' des Filterkopfs 3 weist ein Innengewinde auf, in dem ein glockenförmiges Gehäuse 5 aus einem transparenten Kunststoffmaterial eingeschraubt ist. Innerhalb der hohlzylindrischen Basis 3' ist in einem Abstand zu dem Gehäuse 5 ein hohlzylindrisches Ansatzstück 3'' angeordnet. Über dieses Ansatzstück 3'' ist von außen ein Filterträger 9 mit einem Wasserfilter 7 aufgeschoben, der den stabförmigen Magneten seitlich und unten umschließt, wobei zwischen dem Wasserfilter und dem Gehäuse 5 ein Ringspalt vorgesehen ist. In das Ansatzstück 3'' ist ein Steigrohr 8 eingeschoben, das den Magneten der Länge nach umschließt und am unteren Ende offen ist. Zwischen dem Wasserfilter 7 und dem Steigrohr 8, sowie zwischen diesem und dem Magneten ist jeweils ein Ringspalt angeordnet. Das Ansatzstück 3''Inlet 1 and outlet 2 have couplings 4 for connections. The hollow cylindrical base 3' of the filter head 3 has an internal thread into which a bell-shaped housing 5 made of a transparent plastic material is screwed. A hollow cylindrical extension piece 3'' is arranged within the hollow cylindrical base 3' at a distance from the housing 5. A filter carrier 9 with a water filter 7 is pushed over this extension piece 3'' from the outside, which encloses the rod-shaped magnet at the sides and bottom, with an annular gap being provided between the water filter and the housing 5. A riser pipe 8 is pushed into the extension piece 3'', which encloses the magnet lengthwise and is open at the lower end. An annular gap is arranged between the water filter 7 and the riser pipe 8, as well as between this and the magnet. The extension piece 3''
weist eine Öffnung zum Ablauf 2 auf und ist sonst nur zum Steigrohr 8 hin durchströmbar. Der Weg des zu reinigenden Wassers verläuft somit durch den Zulauf 1 in den Ringspalt zwischen dem Gehäuse 5 und dem Filter 7, der sogleich in den Ringspalt zwischen dem Filter 7 und dem Steigrohr 8 durchdrungen wird. Sodann strömt das Wasser von unten in das Steigrohr 8 und dort entlang der einzelnen Magnetfelder in den Ablauf. Während die, je nach Beschaffenheit des Filters 7, gröberen oder feineren, Schmutzpartikel durch den Filter 7 zurückgehalten werden, findet im Steigrohr die Kalkwandlung statt und es können sich, falls im Wasser vorhanden, kleinere Metallpartikel am Magneten absetzen. Durch diese Zwangsführung im Steigrohr ist gewährleistet, daß die im Wasser vorhandenen Kolloide von den Magnetfeldern in der Art beeinflußt werden, daß sich Kristallisationskerne bilden, die elektrisch neutral im Wasser in der Schwebe gehalten und mit dem Fließwasser ausgeschwemmt werden. Bei bestimmten Anwendungen kann es vorteilhaft sein, wenn im Gehäuse Aktivkohle oder Ionenaustauschermassen angeordnet sind. Die Reinigung des magnetischen Kalkwandlers und es vorgeschalteten Filters erfolgt sehr einfach durch Abschrauben des Gehäuses 5, Abziehen des Filterträgers 9 mit dem Filter 7 und des Steigrohres 8, worauf dann der stabförmige Magnet abgemolken werden kann. Zur Überwachung des Differenzdrucks zwischen Zulauf 1 und Ablauf 2 sind im Filterkopf 3 Manometer 11 angeordnet. Wird die Druckdifferenz zu groß, so ist der Filter zu reinigen. An den Übergängen zwischen dem Gehäuse 5 und dem Filterkopf 3 und zwischen diesem und den Anschlüssen sind Dichtungsringe 6 vorgesehen.has an opening to the drain 2 and can otherwise only be flowed through to the riser pipe 8. The path of the water to be cleaned thus runs through the inlet 1 into the annular gap between the housing 5 and the filter 7, which immediately penetrates into the annular gap between the filter 7 and the riser pipe 8. The water then flows from below into the riser pipe 8 and there along the individual magnetic fields into the drain. While the coarser or finer dirt particles, depending on the nature of the filter 7, are held back by the filter 7, the lime conversion takes place in the riser pipe and, if present in the water, smaller metal particles can settle on the magnet. This forced guidance in the riser pipe ensures that the colloids present in the water are influenced by the magnetic fields in such a way that crystallization nuclei are formed, which are kept suspended in the water in an electrically neutral manner and are washed out with the flowing water. In certain applications it can be advantageous if activated carbon or ion exchange masses are arranged in the housing. The magnetic lime converter and the upstream filter can be cleaned very easily by unscrewing the housing 5, pulling off the filter carrier 9 with the filter 7 and the riser pipe 8, after which the rod-shaped magnet can be milked. To monitor the differential pressure between inlet 1 and outlet 2, pressure gauges 11 are arranged in the filter head 3. If the pressure difference becomes too great, the filter must be cleaned. Sealing rings 6 are provided at the transitions between the housing 5 and the filter head 3 and between this and the connections.
