Description

Die Erfindung betrifft eine Vorrichtung zum Abscheiden von magnetisierbaren Teilen aus schütt- oder fließfähigem GutThe invention relates to a device for separating magnetizable Parts made of pourable or flowable goods

Das genannte Gut kann in jeglicher Form vorliegen, so wie dies bei industriellen oder sonstigen Anwendungen anfällt. Als magnetisierbare Teile kommen Eisenfeilspäne oder jegliche anderen Materialien in Betracht, die magnetisch sind oder sich magnetisieren lassen.The said good can be in any form, as is the case with industrial or other applications. As magnetizable parts possible are iron filings or any other material that are magnetic or can be magnetized.

Eine bekannte Vorrichtung dieser Art umfaßt einen Fallschacht, der in seinem oberen Bereich einen Einlaß für das zu reinigende Gut aufweist, und in seinem unteren Bereich einen Auslaß für das gereinigte, d.h. von magnetisierbaren Teilchen freie Gut, sowie einen Auslaß für die magnetisierbaren Teilchen. Im Schacht befindet sich eine Anzahl von Rosten, die jeweils aus parallel nebeneinander angeordneten feststehenden Rohren bestehen. Die Rohre enthalten jeweils einen Magnetstab.A known device of this type comprises a chute, which in its upper area has an inlet for the material to be cleaned, and in an outlet for the cleaned, i.e. of magnetizable particles free goods, as well as an outlet for the magnetizable particles. There are a number of grates in the shaft, the fixed tubes arranged in parallel next to each other consist. The tubes each contain a magnetic rod.

Beim Betrieb wird das Gut dem Schacht oben zugeführt. Es fällt dabei durch die Roste hindurch. Dabei werden die magnetisierbaren Teilchen durch die Magnetkraft an der äußeren Mantelfläche eines jeden Rohres festgehalten, so daß von magnetisierbaren Teilchen freies Gut weiter nach unten fällt und gegebenenfalls durch einen weiteren Rost hindurchtritt, wo eine weitere Reinigung stattfindet.During operation, the goods are fed into the shaft above. It fails through the grids. The magnetizable particles are thereby Magnetic force held on the outer surface of each tube, so that good free of magnetizable particles falls further down and optionally through another grate where another Cleaning takes place.

Nach einer gewissen Zeitspanne hat sich auf den Mantelflächen der Rohre eine Schicht von magnetisierbaren Teilchen gebildet. Dann werden die Magnetstäbe mit Hilfe einer gemeinsamen Halterung in axialer Richtung aus den Rohren herausgezogen. Mit dieser Axialbewegung der Magnetstäbe wandern auch die auf der Mantelfläche des betreffenden Rohres abgelagerten Teilchen in derselben Richtung, d.h. zu den einem Ende des betreffenden Rohres hin, wo sie mangels Magnethaftkraft abfallen.After a certain period of time, the outer surface of the pipes a layer of magnetizable particles is formed. Then they will Magnetic rods with the help of a common bracket in the axial direction pulled out the pipes. With this axial movement of the magnetic bars also migrate those deposited on the outer surface of the pipe in question Particles in the same direction, i.e. to the one end of that Tube where they drop due to a lack of magnetic force.

Das Verfahren hat den folgenden Nachteil: Das genannte Entfernen der auf den Rohren sitzenden magnetisierbaren Teilchen ist ein diskontinuierlicher Vorgang. Während dieses Vorganges fallen die betreffenden Rohre für den Abscheidungsprozeß aus. Man kann nunmehr sämtliche Rohre während einer gewissen Zeitspanne von magnetisierbaren Teilchen befreien. Dies bedeutet, daß der gesamte Reinigungsprozeß für diese Zeitspanne unterbrochen wird. Man kann auch einen Teil der Rohre von magnetisierbaren Teilchen befreien, und den Reinigungsprozeß mit der verbleibenden Anzahl der Rohre betreiben. Dies bedeutet, daß der Reinigungsprozeß nur bei verringertem Durchsatz durchgeführt werden kann. Beide Arten des Reinigens sind nachteilig.The method has the following disadvantage: the removal of the above the magnetizable particles sitting on the tubes is a discontinuous one Process. During this process, the pipes in question fall for the Deposition process. You can now see all pipes during one free from magnetizable particles for a certain period of time. This means, that the entire cleaning process is interrupted for this period. Part of the pipes can also be freed of magnetizable particles, and run the cleaning process on the remaining number of pipes. This means that the cleaning process only with reduced throughput can be carried out. Both types of cleaning are disadvantageous.

US-A-2 913 113 offenbart eine Vorrichtung zum Abscheiden von magnetisierbaren Teilchen aus Abfall. Gemäß diesem Dokument ist ein angetriebener, wendelförmiger Magnet innerhalb einer drehend angetriebenen zylindrischen Schale vorgesehen. Die bekannten Merkmale aus diesem Dokument sind im Oberbegriff des Anspruchs 1 zusammengefässt.US-A-2 913 113 discloses an apparatus for depositing magnetisable Waste particles. According to this document, a powered, helical magnet inside a rotating driven cylindrical Bowl provided. The known features from this document are in Preamble of claim 1 summarized.

Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung der genannten Art derart zu gestalten, daß das Entfemen von magnetisierbaren Teilchen, die sich auf den Mantelflächen der Rohre niedergeschlagen haben, ohne Beeinträchtigung des Reinigungsprozesses durchgeführt werden kann.The invention has for its object a device of the type mentioned to be designed such that the removal of magnetizable particles, the have deposited on the outer surfaces of the pipes without Impairment of the cleaning process can be carried out.

Diese Aufgabe wäre durch die Merkmale von Anspruch 1 gelöst.This object would be solved by the features of claim 1.

Der Erfinder hat einen sehr eleganten Weg beschritten. Durch Drehen der Magnetstäbe mit wendelartig angeordneten Magneten innerhalb des feststehenden Rohres findet ein kontinuierliches Abführen von magnetisierbaren Teilchen auf der Mantelfläche des Rohres statt. Die Teilchen wandern nämlich entsprechend dem Umlauf der wendelartig angeordneten Magnete an der Mantelfläche des betreffenden Rohres entlang und fallen am Ende des Rohres in einen getrennten Schacht für Eisenteilchen ab. Im Bereich dieses Schachtes ist der Magnetstab unmagnetisch.Der Abscheidungsprozeß wird somit durch das Entfernen der magnetisierbaren Teilchen in keiner Weise beeinträchtigt. The inventor has followed a very elegant path. By turning the Magnetic rods with helically arranged magnets inside the fixed pipe finds a continuous discharge of magnetizable particles on the outer surface of the tube instead. The particles namely migrate according to the circulation of the helically arranged Magnets along the outer surface of the pipe in question and fall on End of the pipe into a separate shaft for iron particles. in the The area of this shaft is non-magnetic The deposition process is thus done by removing the magnetizable Particles in no way affected.

    Die erfindungsgemäße Vorrichtung arbeitet wie folgt:The device according to the invention works as follows:

    Das zu behandelnde Gut ist im vorliegenden Falle ein Produkt aus der Zuckerindustrie. Es ist ein pulverförmiges Gut und enthält Eisenteilchen. Dieses Gut wird in Figur 1 dem dort gezeigten Fallschacht 1 am oben befindlichen Einlaß 1.1 zugeführt. Es fällt durch die Roste 2, 12, 22 hindurch und tritt in weitgehend gereinigter Form, d.h. ohne die Eisenteilchen, am Auslaß 1.2 aus.In the present case, the good to be treated is a product of the Sugar industry. It is a powdery good and contains iron particles. This good is shown in FIG. 1 at the top of the chute 1 shown there located inlet 1.1 supplied. It falls through the grates 2, 12, 22 and occurs in a largely purified form, i.e. without the iron particles, on Outlet 1.2 out.

    Bei dieser Wanderung von oben nach unten fällt das Gut durch die Ritzen zwischen den einzelnen Stäben hindurch. Die Stäbe umfassen, wie erwähnt, jeweils das feststehende Rohr 3 sowie den innenliegenden Wendelmagnetstab 4. Die Eisenteilchen werden durch die magnetischen Felder an der äußeren Mantelfläche der feststehenden Rohre festgehalten. Dadurch, daß sich der Wendelmagnetstab, jeweils umfassend die Welle 4.1, die Wendel 4.2 und die Magnete 4.3, um die eigene Achse dreht, wandern die Eisenteilchen in axialer Richtung eines jeden Rohres zum Eisenteilchen-Abfallschacht (1.3), wo sie wegen fehlendem Magnetfeld abfallen.
