Description
Elektrostatischer Scheider, bei dem eine Stoffbahn über zwei Walzen geführt wird. Bei den bisherigen elektrostatischen Scheidern kann man beobachten, daß sie nur bei trockener Luft einwandfrei arbeiten. Eingebaute Heizvorrichtungen müssen vor Inbetriebnahme der Scheider in Tätigkeit gebracht werden, um die das elektrostatische Feld bildende Stoffbahn und die Luftfeuchtigkeit zu mindern.Electrostatic separator in which a web of material runs over two rollers to be led. With the previous electrostatic separators one can observe that they only work properly in dry air. Built-in heating devices must be brought into operation before the separator is put into operation to ensure that the Electrostatic field forming fabric and reduce the humidity.
Die bis jetzt zur Stoffbahn verwendeten Stoffe, wie Papiergewebe und Paragummi, Zelluloid, Zappon und Zellon, erzeugen wohl ein elektrostatisches Feld, haben jedoch keine lange Lebensdauer.The fabrics used up to now for the fabric, such as paper fabric and Paragum, celluloid, zappon and zellon, probably generate an electrostatic field, however, do not have a long lifespan.
Um eine kräftige Stoffbahn aus Faserstoff o. dgl., die allen mechanischen Einflüssen widersteht, für elektrostatische Scheider zu schaffen, wird die Stoffbahn mit Zelluloid, Zappon oder Zellon so imprägniert, daß jede Faser .des Stoffes hiervon durcbtränkt ist. Durch dieses Imprägnieren wird auch das Eindringen von Luftfeuchtigkeit nahezu behoben.To a strong web of fiber material o. The like., All mechanical Resists influences, for electrostatic separators will create the fabric so impregnated with celluloid, zappon or zellon that every fiber of the fabric of it is saturated. This impregnation also prevents humidity from entering almost resolved.
Diese Stoffbahn wird über zwei mit demselben Stoff wie die Stoffbahn selbst oder mit Wolle, Haarfilz, Zellulose usw. überzogenen Walzen treibriemenartig geführt, wobei sich infolge der Reibung an dem Überzug der Walzen ein elektrostatisches Feld bildet.This panel is made over two of the same fabric as the panel itself or with rollers covered with wool, fur felt, cellulose, etc., like a drive belt guided, with an electrostatic as a result of the friction on the coating of the rollers Field forms.
Das Gut, das ausgeschieden werden soll, wird durch Bandförderung, Fallen, Schütteln, Blasen, Saugen usw. parallel zur Stoffbahn bewegt. Bei letzteren Bewegungsarten wird die Druck- und Saugluft erwärmt.The goods that are to be eliminated are conveyed through conveyor belts, Falling, shaking, blowing, sucking, etc. moved parallel to the fabric. With the latter Types of movement, the compressed and suction air is heated.
Besonders vorteilhaft hat sich das Zwischendurchfallen durch die senkrecht arbeitende Stoffbahn bewährt. Fig. i stellt den Längsschnitt durch eine mit senkrecht arbeitenden Walzen versehene Vorrichtung dar. In den Aufgabetrichter a wird das *zu scheidende Gut aufgeschüttet. Infolge seiner Schwerkraft fällt das Gut in den Zwischenraum der Walzen b und c. Das schwere Gut gelangt in den Kasten d, das leichte Gut wird infolge Reibung der Stoffbahn an den Nichtleiterauflagen e der Walzen b und c elektrostatisch erregt und von der Stoffbahn f angezogen, infolge der treibriemenartigen Bewegung in der Pfeilrichtung zu den Abstreifern g geführt, von diesen abgestreift und in den Kasten lz befördert.Falling through in between has been particularly advantageous through the vertical working length of fabric proven. Fig. I represents the longitudinal section through a with perpendicular working rollers is provided. In the feed hopper a is the * Good to be separated heaped up. As a result of its gravity, the good falls into the Gap between rollers b and c. The heavy goods go into box d, the light ones Good is due to the friction of the fabric web on the non-conductor pads e of the rollers b and c electrostatically excited and attracted to the web f, due to the drive belt-like Movement in the direction of the arrow to the scrapers g, stripped from these and put in the box lz.
In dem Schnitt der Walze b ist eine elektrische" Heizvorrichtung ersichtlich, deren Wärme durch die perforierten Wände i austritt und entweder die Stoffbahn erwärmt, oder- die in dem Raume befindliche Luft trocknet. Beim Arbeiten der Maschine steht die Heizvorrichtung still, währenddem sich die Walze bewegt.In the section of the roller b an electrical "heating device can be seen, whose heat exits through the perforated walls i and either heats the fabric web, or - the air in the room dries. When the machine is working the heater stops while the roller is moving.
