Abstract

Die Erfindung betrifft ein Verfahren zum Entfernen von bei der Boden- oder Wandbearbeitung einer Fläche (21) mittels eines motorischen Schleifwerkzeuges (10) anfallenden Abtrapartikeln, wie Staub und Festpartikeln, über einen an eine Auslassöffnung (12) am Schleifwerkzeug (10) angeschlossenen flexiblen Schlauch (14). Ein vom Lüfter (11) des Schleifwerkzeuges (10) erzeugter großer Luftvolumenstrom hebt die Abtragpartikel von der Fläche (21) ab und fördert diese durch das Schleifwerkzeug (10) hindurch. Dieser Luftstrom wird aus der Auslassöffnung (12) in den Schlauch (14) eingeblasen und durch den Schlauch (14) hindurch zu einer daran angeschlossenen Filtereinrichtung (18) geblasen und durch diese unter Abfiltern der Abtragpartikel hindurch gepresst (Fig.).

Figure imgaf001
The invention relates to a method for removing during the floor or wall processing of a surface (21) by means of a motorized grinding tool (10) resulting Abtrapartikeln, such as dust and solid particles, via a to an outlet opening (12) on the grinding tool (10) connected flexible hose (14). A large air volume flow generated by the fan (11) of the grinding tool (10) lifts the removal particles away from the surface (21) and conveys them through the grinding tool (10). This air flow is injected from the outlet opening (12) into the hose (14) and blown through the hose (14) to a filter device (18) connected thereto and pressed through it by filtering off the removal particles (FIG.
