Description
A.bsaugkopf zur Kehrichtabsaugung mittels Luftumwälzung Die Erfindung betrifft einen Absaugkopf zur Keh- richtabsaugung mittels Luftumwälzung.
Es sind be reits derartige Absaugköpfe bekannt. Sie arbeiten nach dem Prinzip eines Staubsaugers, wobei die an gesaugte Luft nicht wie bei diesem nach der Durch strömung eines Staubabscheiders abgeblasen, sondern dadurch im Kreislauf gehalten wird, dass sie durch einen ringförmig um die Saugöffnung liegenden Blasspalt schräg gegen den Grundriss der Saugmündung wieder auf die zu reinigende Oberfläche geblasen wird. Die ausge blasene Luft reisst den Kehricht vom Boden los und wird mit ihm durch die Saugöffnung angesaugt.
Die angesaug te Luft wird durch eine Leitung dem Kehrichtabscheider zugeführt und von dort erneut über ein Gebläse durch den Blasspalt gepresst. Eine saubere Kehrgutaufnahme ist dann gewährleistet, wenn die Geschwindigkeit, die Menge und der Auftreffwinkel der ausgeblasenen Luft über die ganze Ringfläche konstant gehalten werden. Da dies durch Ungenauigkeiten im Blasspalt, Unebenheiten auf der zu reinigenden Oberfläche usw. unmöglich ist, gibt es Stellen, an denen Umgebungsluft mitgerissen wird, während an anderen Luft Luft aus dem System aus tritt.
Um trotzdem eine saubere Kehrgutaufnahme zu gewährleisten, wurde bereits vorgeschlagen 10 bis<B>207,</B> mehr Luft anzusaugen, als durch den Blasspalt auszubla sen und die überschüssige Luft aus dem System nach dem Gebläse über einen Filter abzublasen. Dieses Ver fahren hat viele Nachteile, da diese überschüssige Luft sehr fein gereinigt werden muss. Es ist schwierig, dieses System mit zwei Luftkreisläufen ins Gleichgewicht zu bringen. Eine zusätzliche Staubentwicklung ist kaum zu vermeiden. Der Nebenstaubabscheider setzt dem Neben luftstrom je nach Füllung mehr oder weniger Widerstand entgegen. Er ist teuer und muss separat entleert und gereinigt werden.
Die Erfindung ist dadurch gekennzeichnet, dass um den Blasspalt eine nach unten offene Ringkammer gelegt ist, derart, dass diese von einem Teil der Blasluft durchströmt wird und diesen Teil von aussen her entlang der zu reinigenden Oberfläche dem Hauptstrom der Blasluft zuführt. Durch entsprechende Dimensionierung der Verbindungsöffnungen zwischen dem Absaugkopf und der Ringkammer kann der Nebenluftstrom genau eingestellt werden. Diese Verbindungsöffnungen können auch durch Schieber oder Blenden einstellbar sein.
In der Zeichnung ist ein Ausführungsbeispiel der Erfindung im Schnitt dargestellt: Die Zeichnung zeigt einen Querschnitt durch einen Absaugkopf nach der Erfindung. Der Absaugkopf weist einen topfartig ausge bildeten Oberteil 1 auf, in welchen eine Blasleitung 2 mündet. Dieser Oberteil 1 umschliesst einen Expansions raum 3 des Absaugkopfes und mündet an der Unterseite in einen ringförmigen Blasspalt 4. In der Mitte des Absaugkopfes ist eine Saugleitung 5 angeordnet. Um den Blasspalt 4 ist eine Ringkammer 7 angeordnet.
Die äussere Begrenzungswand 6 des Blasspaltes 4 besitzt Öffnungen 8, die gleichmässig über den Umfang der Ringkammer 7 verteilt sind. Die Grösse und Anzahl der Öffnungen 8 muss so gewählt werden, dass ein Neben luftstrom von zirka<B>10%</B> durch diese Öffnungen fliesst und der Hauptstrom von zirka<B>90%</B> durch den Blasspalt 4 schräg gegen die zu reinigende Oberfläche geführt wird. Vorteilhafterweise werden die Öffnungen 8 einstellbar gewählt. Der Nebenluftstrom verhindert, dass Blasluft wegen der Bodenunebenheiten oder Verschmutzung des Blasspaltes 4 Kehrgut vom Mundstück her nach aussen bläst.
Die äussere Begrenzung 9 der Ringkammer 7 ist an den Oberteil 1 des Absaugkopfes angeschlossen und endet ungefähr in der Ebene des Austrittes der Blasluft. Die äussere Begrenzung 9 kann aus elastischem Material, z.B. aus Gummi, hergestellt sein.
Die Ringfläche des Blasspaltes kann sowohl kreisför mig wie auch länglich-elliptisch ausgeführt sein. Die Ringkammer 7 muss nur in jedem Fall formlich dem Blasspalt 4 angepasst sein.
A. Suction head for evacuation of rubbish by means of air circulation The invention relates to a suction head for evacuation of rubbish by means of air circulation.
Such suction heads are already known. They work on the principle of a vacuum cleaner, whereby the air that is sucked in is not blown off after flowing through a dust separator, as is the case with this one, but is kept in circulation by opening it again at an angle against the floor plan of the suction opening through a blow gap around the suction opening the surface to be cleaned is blown. The blown air tears the rubbish off the floor and is sucked in with it through the suction opening.
The sucked in air is fed through a line to the waste separator and from there again forced through the blowing gap by a fan. A clean collection of debris is guaranteed if the speed, the amount and the angle of impact of the blown air are kept constant over the entire ring surface. Since this is impossible due to inaccuracies in the blowing gap, unevenness on the surface to be cleaned, etc., there are places where ambient air is entrained while air escapes from the system in other air.
In order to still ensure a clean collection of debris, it has already been proposed 10 to <B> 207 </B> to suck in more air than blow it out through the blower gap and blow the excess air out of the system after the blower via a filter. This process has many disadvantages because this excess air must be cleaned very finely. It is difficult to balance this system with two air circuits. An additional generation of dust can hardly be avoided. The secondary dust separator provides more or less resistance to the secondary air flow, depending on the filling. It is expensive and has to be emptied and cleaned separately.
The invention is characterized in that a downwardly open annular chamber is placed around the blow gap, in such a way that part of the blow air flows through it and feeds this part from the outside along the surface to be cleaned to the main flow of blow air. The secondary air flow can be precisely adjusted by appropriately dimensioning the connecting openings between the suction head and the annular chamber. These connection openings can also be adjustable by means of slides or panels.
The drawing shows an exemplary embodiment of the invention in section: The drawing shows a cross section through a suction head according to the invention. The suction head has a pot-like formed upper part 1, in which a blow line 2 opens. This upper part 1 encloses an expansion space 3 of the suction head and opens into an annular blowing gap 4 on the underside. A suction line 5 is arranged in the center of the suction head. An annular chamber 7 is arranged around the blowing gap 4.
The outer boundary wall 6 of the blow gap 4 has openings 8 which are evenly distributed over the circumference of the annular chamber 7. The size and number of the openings 8 must be selected so that a secondary air flow of approximately <B> 10% </B> flows through these openings and the main flow of approximately <B> 90% </B> through the blowing gap 4 at an angle against the surface to be cleaned. The openings 8 are advantageously chosen to be adjustable. The secondary air flow prevents blown air from blowing debris from the mouthpiece outwards because of the uneven ground or soiling of the blow gap 4.
The outer boundary 9 of the annular chamber 7 is connected to the upper part 1 of the suction head and ends approximately in the plane of the exit of the blown air. The outer boundary 9 can be made of elastic material, e.g. made of rubber.
The annular surface of the blow gap can be designed both circular and elongated-elliptical. The annular chamber 7 only has to be formally adapted to the blow gap 4 in each case.
