Abstract

Description

Reinigungsvorrichtung  cleaning device
Die Erfindung betrifft eine Reinigungsvorrichtung zur Reinigung einer Fläche, insbesondere zur Reinigung einer mit Faserstoffstaub bedeckten Fläche in einer Papier-, Tissue- oder Kartonherstellungsmaschine. The invention relates to a cleaning device for cleaning a surface, in particular for cleaning a fibrous dust-covered surface in a paper, tissue or board making machine.
Insbesondere bei der Herstellung von Tissuebahnen kommt es bei der Herstellung, z.B. im Bereich der Trocknung und Aufrollung, zu einer großen Staubentwicklung. Der Faserstoffstaub lagert sich dabei auf den Oberflächen der Aggrega- te ab. So auch auf den großen Flächen der Trockenhaube. Da diese Flächen durch die Abwärme des Trocken prozesses sehr heiß werden, besteht erhöhte Brandgefahr. In particular, in the manufacture of tissue webs, during manufacture, e.g. in the field of drying and reeling, to a large amount of dust. The pulp dust deposits on the surfaces of the aggregates. So also on the large areas of the drying hood. Since these surfaces are very hot due to the waste heat of the drying process, there is an increased risk of fire.
Der Staub muss von diesen Flächen entfernt werden. Dazu verwendet man entsprechen dem Stand der Technik eine Wasserreinigungsvorrichtung oder bläst den Staub einfach mit einem großen Ventilator von der Fläche.  The dust must be removed from these surfaces. For this purpose, according to the prior art, a water purification device is used or simply blows the dust with a large fan from the surface.
Bei der Wasserreinigung kommt es zu unerwünschten Wasser-Staub Ansammlungen und bei der Ventilatorlösung wird der Staub unkontrolliert durch die Maschinenhalle geblasen und zudem ist es fast unmöglich die Flächen staubfrei zu halten, da der Luftstrom nicht geleitet wird.  Water purification causes unwanted water-dust build-up and, in the case of the fan solution, the dust is blown out of the machine hall in an uncontrolled manner and it is almost impossible to keep the surfaces free of dust as the air flow is not conducted.
Aufgabe task
Der Erfindung liegt daher die Aufgabe zugrunde, eine Vorrichtung zur Verfügung zu stellen, die eine verbesserte Reinigung einer Fläche gewährleistet und zudem einfach und effizient arbeitet. Erfindungsgemäß wird diese Aufgabe durch die Vorrichtung mit den Merkmalen des Anspruchs 1 gelöst. Die Unteransprüche beschreiben vorteilhafte und besonders zweckmäßige Ausgestaltungen der Erfindung. Wie bereits im Stand der Technik wird erfindungsgemäß eine Reinigungsvorrichtung vorgeschlagen, mit der eine Staub bedeckte Fläche, insbesondere eine Fläche in einer Papier-, Tissue- oder Kartonherstellungsmaschine, mit einem Luftstrom gereinigt wird. Wobei ein dünner Luftvorhang, der mittels einer Blasluftdüse erzeugt wird, zu Reinigung benutzt wird. The invention is therefore based on the object to provide a device that ensures improved cleaning of a surface and also works easily and efficiently. According to the invention, this object is achieved by the device having the features of claim 1. The subclaims describe advantageous and particularly expedient embodiments of the invention. As in the prior art, a cleaning device is proposed according to the invention, with which a dust-covered surface, in particular an area in a paper, tissue or board making machine, is cleaned with a stream of air. Whereby a thin air curtain, which is produced by means of a blowing air nozzle, is used for cleaning.
Die Blasluftdüse weist, zur Erzeugung des dünnen Luftvorhangs, einen sehr schmalen Luftaustrittsspalt auf, durch den Druckluft mit vorzugsweise 50bar hin- durchgepresst wird. Um den dünnen Luftvorhang an den schmalen Seiten zu leiten ist eine Leitvorrichtung vorgesehen, die gegenüber der Düsenaustrittsöffnung so angeordnet ist, dass der Luftstrahl von den Leitblechen seitlich geführt wird. In order to produce the thin air curtain, the blowing air nozzle has a very narrow air outlet gap, through which compressed air with preferably 50 bars is pressed. In order to guide the thin air curtain on the narrow sides of a guide device is provided, which is arranged opposite the nozzle outlet opening so that the air jet is guided by the baffles laterally.
Die Leitbleche der Leitvorrichtung weisen eine Krümmung nach außen auf, vorzugsweise eine Kreissegmentkrümmung, die bewirkt, dass der Luftstahl gezielt in die Breite gezogen wird. So wird Vorteilhafterweise erreicht, dass die Düse nicht über die gesamte Flächenbreite reichen muss, sondern aus mehreren Blasluftdüsen bestehen kann. Es hat sich herausgestellt, dass Blasdüsen mit 230mm Düsenbreite die besten Ergebnisse bei einem Mittenabstand von 600 bis 950mm, vorzugsweise 760mm zu erreichen. The baffles of the guide device have a curvature to the outside, preferably a circular segment curvature, which causes the air steel is selectively drawn in the width. Thus, it is advantageously achieved that the nozzle does not have to extend over the entire area width, but can consist of several Blasluftdüsen. It has been found that tuyeres with 230mm nozzle width to achieve the best results with a center distance of 600 to 950mm, preferably 760mm.
Um die zu reinigende Fläche trotz der Düsenunterbrechung möglichst komplett zu reinigen, wird die Düsenaustrittsöffnung zudem gegenüber der zu reinigenden Fläche so angeordnet ist, dass der Abstand zur Vorderkante der Fläche 200 bis 400mm beträgt und die Düsenaustrittsöffnung gegenüber der Flächenebene eine Abstand von 50 bis 100mm hat. Des Weiteren wird vorgeschlagen, dass die nebeneinander angeordneten Düsen intermittiered mittels eines Ventiels angesteuert werden. So kann die Druckluftbereitstellung effektiv genutzt werden. In order to clean the surface to be cleaned as completely as possible despite the nozzle interruption, the nozzle exit opening is also arranged opposite the surface to be cleaned so that the distance to the front edge of the surface is 200 to 400mm and the nozzle exit opening with respect to the surface plane has a distance of 50 to 100mm , Furthermore, it is proposed that the juxtaposed nozzles are controlled intermittently by means of a Ventiels. Thus, the compressed air supply can be used effectively.
Figurenbeschreibung figure description
Die erfindungsgemäße Lösung wird nachfolgend anhand von Figuren erläutert. Darin ist im Einzelnen Folgendes dargestellt: Figur 1 zeigt eine erfindungsgemäße Vorrichtung mit der Druckluftdüsenanordnung  The solution according to the invention is explained below with reference to figures. The following is shown in detail: FIG. 1 shows a device according to the invention with the compressed-air nozzle arrangement
Figur 2 zeigt eine Seitenansicht im Schnitt der Druckluftdüsenanordnung  Figure 2 shows a side view in section of the compressed air nozzle assembly
In Figur 1 ist eine erfindungsgemäße Vorrichtung mit der Druckluftdüsenanordnung gezeigt. Die Druckluftdüsen 1 werden über den Ventilblock 6 mit Druckluft 7 versorgt. Damit der aus der Düsenöffnung 4 austretende Luftstrom oder Luftvorhang eine entsprechende Reichweite und Reinigungswirkung, hat ist vorzugsweise ein Luftdruck von 50bar vorhanden. FIG. 1 shows a device according to the invention with the compressed-air nozzle arrangement. The compressed air nozzles 1 are supplied via the valve block 6 with compressed air 7. In order for the air flow or air curtain emerging from the nozzle opening 4 to have a corresponding range and cleaning effect, an air pressure of 50 bar is preferably present.
Über den Ventilblock sind die Düsen einzeln anzusteuern. Werden die Düsen hintereinander angesteuert, kann die Druckluftversorgung kleiner und effizienter ausgelegt werden. The nozzles are to be individually controlled via the valve block. If the nozzles are controlled in series, the compressed air supply can be made smaller and more efficient.
Zur Verbesserung der Reinigungswirkung ist eine seitliche Führung des Luftstrahls vorgesehen. Dazu sind seitlich an den Luftaustrittsdüsen Leitbleche 3 angeordnet, die den Luftstrahl aufweiten. To improve the cleaning effect a lateral guidance of the air jet is provided. For this purpose, baffles 3 are arranged laterally on the air outlet nozzles, which expand the air jet.
Die Düsen sind, wie auch im Schnitt in Figur 2 dargestellt, voneinander und gegenüber der Vorderkante der Fläche 2 beabstandet. Die Abstände sind so ge- wählt, dass die Reinigungswirkung optimiert ist und die Restfläche die nicht vom optimalen Luftstrom erfasst wird möglichst klein zu halten. „ The nozzles are, as also shown in section in Figure 2, spaced from each other and from the front edge of the surface 2. The distances are selected so that the cleaning effect is optimized and the remaining area that is not covered by the optimal air flow is kept as small as possible. "
