Abstract
Description
Die Erfindung betrifft eine Entstaubungssonde gemäß dem Oberbegriff des Hauptanspruchs.The invention relates to a dedusting probe according to the preamble of the main claim.
Die Entstaubung von Papierbahnen mittels Entstaubungssonden ist ein bis heute noch nicht befriedigend gelöstes Problem.The dedusting of paper webs by means of dedusting probes is a problem that has not yet been satisfactorily solved.
Der Efindung liegt deshalb die Aufgabe zugrunde, eine gattungsgemäße Entstaubungssonde so weiterzubilden, daß ein hoher Wirkungsgrad bei der Enstaubung erzielt werden kann.The invention is therefore based on the object of developing a generic dedusting probe in such a way that a high degree of efficiency can be achieved in dedusting.
Diese Aufgabe wird bei einer gattungsgemäßen Sonde gemäß dem Oberbegriff des Hauptanspruchs erfindungsgemäß durch dessen kennzeichnende Merkmale gelöst.This object is achieved in a generic probe according to the preamble of the main claim according to the invention by its characterizing features.
Eine schnell bewegte Bahn, beispielsweise aus Papier reißt mit zunehmender Geschwindigkeit Luft mit sich, die sich parallel zu der Bahn bewegt. Unmittelbar im Bereich einiger hunderstel Millimeter über der Bahn besteht hierbei eine laminare Strömung, die annähernd der Geschwindigkeit der Bahn entspricht und linear mit dem Abstand zur Papierbahn abnimmt. Die aus der Blasdüse austretende Anblasluft wirkt hierbei der bewegten Bahn entgegen und reißt die parallel zur Papierbahn verlaufende, faßt laminare Luftströmung auf. Dadurch wird der Staub, der sich in dieser Luftströmung bewegt sowie auch der nicht sehr stark anhaftende Staub von der Bahn aufgewirbelt und in Richtung des Absaugkanales gedrängt. Der Unterdruck in dem Absaugkanal ist so bemessen, daß der aufgewirbelte Staub abgesaugt werden kann. Die Hochspannungseleketrode, die im inneren der Sonde angeordnet ist, werden sowohl die Bahn als auch die Staubpartikel entladen, so daß ein leichteres Ablösen durch die Luft von der Blasdüse und Absaugung durch den Saugkanal möglich wird. Die Ausrichtung der Hochspannungselektrode und der Blasdüse ist so bemessen, daß sich die beiden Ebenen in einer Geraden schneiden, die genau in der Bahn liegt. In dieser Linie wird also die Entladung optimal bewirkt. Zugleich greift dort die Luft nach Art eines Rakels an, wodurch das Lösen der Staubpartikel bewirkt werden kann. Durch die Anordnung des Absaugkanals entgegen der Bewegungsrichtung der Bahn und in Blasrichtung der Blasdüse im unteren Bereich nahe der Bahn ist ferner sichergestellt, daß die aufgewirbelten Staubpartikelchen problemlos abgesaugt werden können. Zu diesem Zweck trägt auch die Ausrichtung der Einströmrichtung der Kanalöffnungen des Absaugkanals bei, die in einer vierten Ebene liegen, die mit der Bahn einen spitzen Winkel einschließt.A rapidly moving web, for example made of paper, entrains air with increasing speed which moves parallel to the web. Immediately in the range of a few hundredths of a millimeter above the web there is a laminar flow which approximately corresponds to the speed of the web and decreases linearly with the distance to the paper web. The blowing air emerging from the blowing nozzle counteracts the moving web and tears the laminar air flow running parallel to the paper web. As a result, the dust that moves in this air flow and also the not very strongly adhering dust are whirled up by the web and forced in the direction of the suction channel. The negative pressure in the suction channel is dimensioned so that the whirled up dust can be suctioned off. The high-voltage electrode, which is arranged inside the probe, discharges both the web and the dust particles, so that an easier detachment by the air from the blowing nozzle and suction through the suction channel is possible. The orientation of the The high-voltage electrode and the blow nozzle are dimensioned so that the two planes intersect in a straight line that lies exactly in the path. The discharge is thus optimally effected in this line. At the same time, the air attacks there like a squeegee, which can cause the dust particles to be loosened. The arrangement of the suction channel counter to the direction of movement of the web and in the blowing direction of the blowing nozzle in the lower region near the web also ensures that the swirled up dust particles can be suctioned off without problems. The orientation of the inflow direction of the channel openings of the suction channel, which lie in a fourth plane, which forms an acute angle with the web, also contributes to this purpose.
Ferner ist mit Vorzug auf der anderen Seite der Bahn bezüglich der Sonde eine metalliche Feldplatte montiert, die an einen Hochspannungsgenerator mit variabler Spannung und Frequenz angeschlossen ist. Durch dieses Wechselfeld werden die Kräfte zwischen Staubpartikel und Bahn augehoben. Ferner können in Abhängigkeit von der Geschwindigkeit der Bahn die Strömungsgeschwindigkeit der Blasund Saugluft eingestellt werden.Furthermore, a metal field plate is preferably mounted on the other side of the track with respect to the probe, which is connected to a high-voltage generator with variable voltage and frequency. This alternating field increases the forces between the dust particle and the web. Furthermore, the flow speed of the blowing and suction air can be adjusted depending on the speed of the web.
