Description
Magnetscheidung Die bekannten Magnetscheider trennen das magnetische und magnetisierbare Gut vom anderen nicht sauber. Wenn das abzuscheidende Gut wertvoll ist, lohnen sich besondere Einrichtungen.Magnetic separation The well-known magnetic separators separate the magnetic and magnetizable good from the other not clean. When the goods to be separated are valuable special facilities are worthwhile.
Die Erfindung besteht darin, daß in vorhandenen oder neu zu bauenden Magnetscheidern Einrichtungen eingebaut -,verden, die das Gut durch Schall beliebiger Frequenz aufrütteln.The invention consists in that in existing or to be built Magnetic separators built in -, verden, which the material by sound of any Shake up frequency.
Akustische Schwingungen im Bereich des Hörschalles und solche im Bereich des Ultraschalles versetzten Mischungen aus Bestandteilen ähnlicher Abmessungen derart in Schwingungen, daß die größeren von .den kleineren Teilen abfallen und Adhäsionen aufgehoben werden. Mischungen aus Teilchen ähnlicher Abmessungen weisen immer solche Größen auf, die in Resonanz zu den erregenden Schwingungen gelangen. Diese Teile lösen sich besonders aus den anderen.Acoustic vibrations in the area of audible sound and those in the area the ultrasound mixed mixtures of components of similar dimensions in such a way in vibrations that the larger of the smaller parts fall off and Adhesions are lifted. Mixtures of particles of similar dimensions have always those quantities that arrive in resonance with the exciting vibrations. These parts are particularly detached from the others.
In geeigneten Fällen können die akustischen. Erregungen, verbunden werden mit Einflüssen strömender Luft oder bewegter Gase. Dies geschieht vorteilhaft, indem die akustischen Wellen der Gas- oder Luftwirkung entgegenarbeiten. Die Luft soll ähnlich von Wälzvorgängen wirken. Die akustischen Wellen lösen wähnend des Wälzers die Teile voneinander.In appropriate cases, the acoustic. Excitements, connected are influenced by flowing air or moving gases. This is done advantageously in that the acoustic waves counteract the effects of gas or air. The air should act in a similar way to rolling processes. The acoustic Loosen waves during the tome the parts of each other.
Da es sich bei der Magnetscheidung von feinen Stäuben u.,dgl. vielfach um Partikel handelt, die in Größen unter i mm bis herab zu -i ,u und noch darunter anfallen" ist die Anwendung von Ultraschall vorteilhaft. Der Resonanzdurchmesser für i MHz liegt z. B. bei 4,u, -derjenige für i kHz hei 3 mm. Die Ultraschallwellen werden mit Apparaten handelsüblicher Art erzeugt und als gerichtete Wellen auf die Gemische zur Wirkung gebracht. Da .die Anwendung hauptsächlich in Luft erfolgt, empfiehlt sich die Benutzung von schwingenden Luftsäulen, z. B. nach Hartmann (Hartmann-Generator).Since the magnetic separation of fine dusts and the like. multiple Particles are concerned with sizes below i mm down to -i, u and even below the use of ultrasound is advantageous. The resonance diameter for i MHz is z. B. at 4, u, -the one for i kHz at 3 mm. The ultrasonic waves are generated with apparatus of a commercial type and as directed waves on the Mixtures brought into effect. Since it is mainly used in air, the use of vibrating air columns is recommended, e.g. B. Hartmann (Hartmann generator).
An Stelle der Erregung von Luftsäulen oder Übertragung des Ultraschalles über Luft kann auch der Trägerdes Gutes, z. B. ein Stahl- oder Metallband, der Boden eines Gefäßes od. dgl. durch Ultraschall oder auch durch andere Schallarten und -freduenzen erregt werden. Die Wirkung pflanzt sich dann auf das auf dem Boden od. dgl. ruhende Gemisch fort.Instead of exciting air columns or transmitting ultrasound The carrier of the goods, e.g. B. a steel or metal band, the floor a vessel or the like by ultrasound or by other types of sound and -reduences are aroused. The effect is then planted on the od on the ground. the like. dormant mixture continued.
In .gleicher Weise können Schallgeber beliebiger Art und bekannter Ausführung mit Teilen des Magnetscheiders so verbunden werden, daß diese Teile durch Körperschall erregt werden und diese Schwingungen auf das Gemisch übertragen.In the same way, sound generators of any type and known Execution with parts of the magnetic separator are connected so that these parts through Structure-borne noise are excited and these vibrations are transferred to the mixture.
Akustische Schwingungen jedweder Art können auch .auf die Flächen -der Magnete selbst zur Wirkung ,gebracht werden, damit z. B. aus dem durch den Magneten aufgenommenen Gut die nichtmagnetischen Partikel wieder herausgeschleudert werden. Dies ist gegeben, weil bei Erschütterungen das magnetische oder -magnetisierte Gut am Magneten fest haftet, während das andere abfällt.Acoustic vibrations of any kind can also be brought into effect on the surfaces of the magnets themselves, so that z. B. from the material picked up by the magnet, the non-magnetic particles are thrown out again. This is the case because the magnetic or vibrations - Good magnetized to the magnet will stick firmly, while the other falls.
