Description
Spülquerschnitte an Abstreifern von Permanentmagnetsystemen Filtersysteme mit permanenten Magneten haben in der Industrie eine grosse Verbreitung gefunden0 Im ZuHe fortschreitender Automatisierung haben sich eine Reihe verschiedenartiger Abstreifsysteme für die Abscheidung der anefa lienen Verunreinigungen entwickelte Hierdurch ergab sich wiederum die Möglichkeit,sehr grosse Magnetsysteme zu schaffen,wo bei höchstmöglicher magnetischer Besetzung und bei sehr niedrigen Flüssigkeitsbewegungen in sehr enden Strömungsspalten Verschmutzungen von bisher noch nicht erkannter Feinheit ausgeschieden werden konnten, Die abgeschiededenen Verschmutzungen reagieren zum Teil nur sehr schwach magnetisch und weisen bindungen über adhäsiv wirkende Produkte wie Clalterungsbestandteile oder ähnlichem auch zu unmagnetisch reagierender Substanz hin.Flushing cross-sections on wipers of permanent magnet systems, filter systems with permanent magnets have found widespread use in industry0 As automation advances, a number of different types have emerged Stripping systems developed for the separation of the anefa lien impurities This in turn made it possible to create very large magnet systems wherever with the highest possible magnetic occupation and with very low fluid movements in the very end of the flow gaps, soiling of a previously unrecognized degree of delicacy could be excreted, The deposited dirt reacts to the Partly only very weakly magnetic and show bonds via adhesive products such as aging constituents or the like, also to non-magnetic reacting substance there.
bei Magnetsystemen, die durch Ablassen oder Herausheben oder durch normale 3pülung des Behälterinhalts gereinigt werden, bewirkt zumeist fehlender Auftrieb bei Heraushebung aus der Flüssigkeit oder intensive opülung im gefüllten Behälterinhalt eine Lösung der Verbindung uer angefallenen Koagulationsprodukte, wobei sich wiederum £?remdbindungen wie zOBo Öl und Eisenseifenverbindungen etc. von der magnetisch abgnetisch abgeschiedenen Substanz lösen.in the case of magnet systems, which can be activated by lowering or lifting out or by normal 3 flushing of the container contents usually results in missing Buoyancy when lifted out of the liquid or intense opulification in the filled The contents of the container are a solution of the compound of the coagulation products that have accumulated, where in turn remnants such as zOBo oil and iron soap compounds etc. from the magnetically separated substance.
Insbesondere bei Magnetsystemen, die in der Flüssigkeitsfüllung auch opulung bei mechanischer Abstreifung gereinigt werden, zeigt sich, daß die technisch erforderlichen Spülmengen zur restlosen Entfernung der abgeschiedenen Schmutzbestandteile aus dem Behalterinhalt aufwendig hohe Volumen sein müssen.Especially with magnet systems that are also used in the liquid filling opulung are cleaned with mechanical stripping, it turns out that the technically required flushing quantities for the complete removal of the separated dirt components the contents of the container have to be expensive and high volumes.
beizu geringen Spülmengen tritt ausserdem die Gefahr ein, daß die mechanische Abstreifbewengung der Spülströmung voreilt und somit durch die mechanische Abstreifung die Verunreinigung gelöst und auf die zu gering beflutete Reinfiltratseite umschlaen kann.with too small flushing quantities there is also the risk that the mechanical Abstreifbewengung leads the flushing flow and thus through the mechanical Stripping off the contamination and on the insufficiently flooded pure filtrate side can umschlaen.
Bei iViagnetsystemensdie durch Heraushebung aus der Flüssigkeit gereinigt oder durch Spülung und Abstreifung in der Flüssigkeitsc füllung gereinigt werden liegt ausserdem der Nachteil vor daß der Betrieb unterbrochen werden muss bezw. ein Teil des Magnetsystems während der Heraushubzeit nicht arbeitsleistend im Einsatz steht0 Durch die Anwendung von Spülquerschnitten zur Verunreinigungs ab leitung im Bereich der Abstreifer von Permanentmagnetsystemen ist nunmehr ein Mittel gefunden worden,die. beschriebenen Mängel abzuschaffeno Durch die Anordnung der Spülquerschnitte im Bereich der Abstreifer kann durch Einstellung einer Strömung durch regulierbares Druckgefälle während der Abstreifzeit eine Strömung erzielt werden,welche die angefallenen Verunreinigungen in idealer Weise abführt und zur weiteren Verarbeitung nach außen ab leitet Diese Operation kann wegen des relativ geringen Spülflüssigkeitsabganges auch unter vollen Betriebsbedingungen durchgeführt werden0 Die Anordnung des beschriebenen Systemes geht aus beiliegendem Zeichnungsblatt hervor0 Hierbei sind die in verschiedenartiger Form ausführbaren Spülquerschnitte-mit (1) bezeichnet,wobei die Abstreifer für die mechanische Entfernung der Verunreinigung durch Bewegung mit (2) bezeichnet sind.In the case of iViagnet systems, they are cleaned by lifting them out of the liquid or cleaned by rinsing and wiping in the liquid filling there is also the disadvantage that the operation must be interrupted BEZW. part of the magnet system not performing work during the lifting time stands0 Through the use of flushing cross-sections for draining off contamination A means has now been found in the field of wipers for permanent magnet systems been that. Abolish the deficiencies described o Through the arrangement of the flushing cross-sections in the area of the scraper can be regulated by setting a flow through Pressure gradient can be achieved during the stripping time, which the accumulated Discharges impurities in an ideal way and for further processing to the outside This operation can be carried out because of the relatively low flushing liquid discharge can also be carried out under full operating conditions 0 The arrangement of the described The system can be seen from the attached drawing sheet Form executable flushing cross-sections — denoted by (1), the scrapers for the mechanical removal of the contamination by movement are denoted by (2).
Die Magnetsysteme können hierbei aus einer oder mehreren zylindrischen Walze oder längeren Stäben bxw, Kerzen anderer Querschnitte bestehen (3) oder die Abstreifbewegungen erfolgen durch Rotation eines Körpers in Form eines Ringes,einer Scheibe oder eines Zylinders verschiedenartiger Mantelstruktur (4) oder das abzustreifende System wird in achsialer oder eben zur Fläche verlauf enden Richtung abgestreift,wie dies bei Hohlkörpern oder andersartigen ebenen Körpern bis zu geraden Platten hin möglich ist (5).The magnet systems can consist of one or more cylindrical Roller or longer rods bxw, candles of other cross-sections (3) or the Wiping movements are carried out by rotating a body in the form of a ring, a Disc or a cylinder of various types of jacket structure (4) or that to be stripped off The system is stripped off in the axial direction or in the direction that is flat to the surface, such as this in the case of hollow bodies or other types of flat bodies up to straight plates is possible (5).
Die Abstreifbewegungen können hierbei in der einen Richtung oder hin und hergehend erfolgen wobei auch die Abstreifer einseitig oder doppelseitig mit gemeinsamem oder getrennten Spülkanal denkbar sind.The wiping movements can be in one direction or there and proceeding with the wipers on one or both sides common or separate flushing channel are conceivable.
