Description

Dauermagnetfilter Gegenstand des Patents 73¢r37 ist ein Dauermagnetfilter, bei dem im Innenraum des Filters Körper angeordnet sind, die die magnetisierbaren Stoffe des Gutes anziehen. Ein solcher Dauermagnetfilter weist zwei oder mehreres Steg- bzw. ringförmige oder rechteckig geschlossene Dauermagneta auf. Die gleichnamigen Pole dieser Mar gnete sind durch ferromagnetische Platten verbunden, und der Innenraum ist mit ferromagnetischen Teilen angefüllt, die mit Zwischenraum nebeneinander oder übereinander angeordnet sind. Die Platten, die die gleichnamigen Pole verbinden, speisen, diese ferromagnetischen Teile im Innenraum des Filters, so da.ß ein Kraftfluß entsteht, der den Raum gleichmäßig durchsetzt. Die Polplatten und die Teile im Magnetinnenraum werden vorzugsweise aus, Weicheisen hergestellt.Permanent magnetic filter The subject of patent 73 ¢ r37 is a permanent magnetic filter, are arranged in the interior of the filter body, the magnetizable Put on fabrics of the goods. Such a permanent magnetic filter has two or more Bar or ring-shaped or rectangular closed permanent magnets. The same name Poles of these mar gnete are connected by ferromagnetic plates, and the interior is filled with ferromagnetic parts that are next to each other or with a gap are arranged one above the other. The plates that connect the poles of the same name, feed, these ferromagnetic parts in the interior of the filter, so da.ß a power flow that evenly pervades the room. The pole plates and the parts inside the magnet are preferably made of soft iron.

Die Körper, die im Innern des Magnets angeordnet sind und die den eigentlichen filtrieirend.en magnetischen Streufluß hervorrufen, können beispielsweise stab- oder spiralförmig sein.. Sie können aber auch aus gelochten Blechen. bestehen, die übereinander angeordnet sind, wobei die abschließenden ferromagnetischen Platten gelocht sein müssen. In einem solchen Fall wird auch zweckmäßig mit einem ringförmigen oder rechteckig geschlossenen Dauermagnet gearbeitet. An Stelle der gelochten Bleche kann auch beispielsweise eine Kugelpackung oder eine Spänefüllung benutzt werden..The bodies which are arranged inside the magnet and which the cause actual filtering magnetic leakage flux, for example be rod-shaped or spiral-shaped .. But they can also be made from perforated sheet metal. exist, which are arranged one above the other, with the final ferromagnetic plates must be perforated. In such a case, it is also advisable to use an annular one or rectangular closed permanent magnet worked. Instead of the perforated metal sheets can also be, for example, a spherical packing or a chip filling to be used..

An die Pole der Dauermagnete- kann auch ein Gewerbe aus ferromagnetischem Werkstoff an.-geschlossen werden, dessen Kette und Schuß entgegengesetzt polarisiert sind. Am zweckmäßigsten wird hierbei die Anordnung so getroffen, daß das Gewebe an, Ansätzen befesrtigt ist, die vom, den entsprechenden ferramagnetischen .Polplatten in den Filterraum hineinragen.A ferromagnetic trade can also be attached to the poles of the permanent magnets Material to be connected, whose warp and weft polarize in opposite directions are. Most expediently, the arrangement is made so that the fabric on, approaches is attached, which from, the corresponding ferramagnetic .Polplatten protrude into the filter space.

Dauermagnetfilter dieser Art sind. entwickelt worden, um magnetisierbare Stoffe aus strömenden Flüssigkeiten abzuscheiden, wie beispielsweise Viskose, Öl, Quecksilber u. dgl.Permanent magnetic filters of this type are. designed to be magnetizable To separate substances from flowing liquids, such as viscose, oil, Mercury and the like

Es hat sich nun gezeigt, daß Dauermagnetfilter von der Art, wie sie, durch Patent 734137 geschützt sind, auch in. hervorragendem Maß geeignet sind, strömende Gase zu reinigen, obwohl hierbei mit magnetisierbardn Teilchen von außerordentlich geringer Größe gerechnet werden muß. Es hat sich nämlich gezeigt, daß in Gasleitungen, vor- allen Dingen aber auch in der Luft von Werkstätten od. dgl., Eisenabrieb von einer solchen Feinheit vorhanden ist, daß er im allgemeinen nicht bemerkt und auch nicht als störend empfunden, wird. Wenn allerdings beispielsweise in eine solche Gasleitung ein mit magnetischen Teilen versehenes Meßinstrument eingebaut wird; so können sich im Laufe der Zeit durch die angesammelten Eisenteilchen erheblichei Störungen der Meßinstrumente ergeben. Elektromotoren sind meist so gebaut, daß -sie einen Luftstrom ansaugen, der der Kühlung des Motors dient. Wenn ein solcher Motor mit Dauermagneten ausgerüstet ist, d. h. also mit Teilen, die nicht umgepolt werden, so kann der in@ der Luft feinverteilte Eisenabrieb zu Störungen Anlaß geben, weil sich im Laufei der Zeit die Eisenteilchen an den Polen der Dauermagnete sammeln. und, zu magnetischen Kurzschlüssen Veranlassung geben.It has now been shown that permanent magnetic filters of the kind they are protected by patent 734137, are also eminently suitable for flowing To purify gases, although in this case with magnetizable particles of extraordinarily small size must be expected. It has been shown that in gas pipes, especially in the air of workshops or the like, iron abrasion from such delicacy exists that he generally goes unnoticed and also is not perceived as annoying. However, if, for example, in such a A measuring instrument provided with magnetic parts is installed in the gas line; in the course of time, the accumulated iron particles can significantly break down Malfunctions of the measuring instruments result. Electric motors are usually built in such a way that -they suck in a stream of air that is used to cool the motor. If such an engine is equipped with permanent magnets, d. H. so with parts that are not reversed, so the iron abrasion finely distributed in the air can give rise to disturbances because Over time, the iron particles collect at the poles of the permanent magnets. and give rise to magnetic short circuits.

Störungen dieser Art können, obwohl die abzuscheidenden Teilchen vielfach außerordentlich klein sind, bemerkens.werterweise beseitigt werden, wenn Dauermagnetfilter nach Patent 734137 zum Abscheiden der magnetisierbaren Stoffe vorgesehen werden, insbesondere wenn man: solche Dauermagn.etfilter- in Gasleitungen, in Luftzuführungen zu Elektromotoren, in Ventilatorleitungen od. dgl. einbaut.Disturbances of this kind can occur, although the particles to be deposited are multiple are extraordinarily small, notably can be eliminated when using permanent magnetic filters can be provided according to patent 734137 for separating the magnetizable substances, especially if you have: such permanent magnet filters in gas lines, in air supplies to electric motors, in fan lines or the like.
