Description

Die Erfindung betrifft einen Staubsauger mit unverbrennlichem Filter unter Verwendung von Funken o. dgl. zurückhaltendem Asbestgewebe.The invention relates to a vacuum cleaner with an incombustible filter using sparks or the like restrained asbestos fabric.

Bei der Herstellung beispielsweise von Industriestaubsaugern hat sich beobachten lassen, daß die in den Staubsaugern als Filterglieder angeordneten, meist aus Baumwollgewebe bestehenden Schläuche, Säcke oder Taschen durch mitgerissene Funken oftmals in Brand geraten.In the manufacture of industrial vacuum cleaners, for example, has been observed let that arranged in the vacuum cleaners as filter elements, mostly made of cotton fabric Existing hoses, sacks or bags can often catch fire due to the sparks carried along.

Es wurde versucht eine Verminderung der Entzündungsgefahr dadurch zu erreichen, daß die Filterglieder zum Schutz vor Entzündung imprägniert wurden. Auch flieser Schutz hat sich als nicht hinreichend erwiesen.Attempts have been made to reduce the risk of inflammation in that the filter members have been impregnated to protect against ignition. Even tiles have protection proved to be insufficient.

Filterglieder aus Asbestgewebe in Verbindung mit Metallsieben oder imprägnierten Mineralfaserstoffen sind an sich nicht neu.Filter elements made of asbestos fabric in connection with metal sieves or impregnated Mineral fibers are not in themselves new.

Demgegenüber, will die Erfindung nicht nur die Filterfähigkeit des Baumwollgewebes oder anderer brennbarer Stoffe voll erhalten, sondern auch die Raumform des bekannten Staubsaugers bzw. die Beutel- 0. dgl. Form des Filters selbst. Es erschien zunächst nicht möglich, das Asbestgewebe der vorhandenen Filterform anzupassen. Dieses Vorurteil ist aber durch die angestellten Versuche behoben worden, so daß ein Staubsauger bzw. ein Filter geschaffen werden konnte, die äußer-Hch den vorhandenen Arten gleichen, jedoch eine unvergleichliche Brandsicherheit gewährleisten. In contrast, the invention does not only want the filtering ability of the cotton fabric or other flammable substances are fully preserved, but also the spatial shape of the familiar Vacuum cleaner or the bag-like shape of the filter itself. It did not appear at first possible to adapt the asbestos fabric to the existing filter shape. That prejudice is but has been remedied by the attempts made, so that a vacuum cleaner or a Filters could be created that outwardly resemble the existing species, however guarantee incomparable fire safety.

Erfindungsgemäß ist das dem üblichen Baumwollfilter vorgeschaltete Asbestgewebe in seiner Gestalt ebenso ausgebildet wie das Baumwollgewebe. Zweckmäßig ist hierbei der Zusammenhang zwischen dem Filterbeutel oder Filtersack aus Baumwolle und dem Innen- oder Außenmantel aus feuerfestem Geflecht oder Gewebe, z. B. Asbest, lose, so daß dadurch ein wärmeisolierender Luftzwischenraum zwischen Baumwollgewebe und Asbest gebildet ist, welcher gleichzeitig ein übermäßiges Heißwerden des Baumwollgewebes verhütet.According to the invention, the asbestos fabric upstream of the usual cotton filter is just as developed in its shape as the cotton fabric. It is useful here the connection between the filter bag or filter sack made of cotton and the inner or outer jacket made of fireproof Braid or fabric, e.g. B. asbestos, loose, so that a heat-insulating air gap between cotton fabric and asbestos is formed, which at the same time causes excessive heating of the cotton fabric prevent.

Für die Erfindung sind mannigfache Abänderungen innerhalb des Erfindungsgedan* kens möglich. Wird z.B. das Staubfilter-, glied in Schlauchform gehalten, so mag die Schlauchinnenwandung aus Asbestgewebe be- ■ stehen, um die sich alsdann das als Staubfilter dienende Baumwollgewebe als zweite Schicht herumlegt. Das Asbestgewebe kann hierbei so stark gewählt und z. B. durch Draht ίο versteift werden, daß es gleichzeitig das formgebende Innengerüst für den Schlauch darstellt.Various modifications within the inventive concept are necessary for the invention * kens possible. If, for example, the dust filter element is held in the shape of a hose, it may The inner wall of the hose consists of asbestos fabric, around which the second cotton fabric, which serves as a dust filter, is placed Shift laying around. The asbestos fabric can be chosen so strong and z. B. by wire ίο be stiffened so that it is also the shaping inner structure for the hose represents.

Ist an Stelle des Schlauches z.B. die Beutel- oder Sackform gewählt, so kann der Beutel oder Sack einen Innen- oder Außenmantel aus einem feuerfesten Geflecht, lose übereinandergestülpt oder festgemacht, aufweisen. If, for example, the bag or sack shape is selected instead of the hose, the Bag or sack with an inner or outer jacket made of a fire-proof braid, loose put on top of one another or fastened.

Hat das Staubfilterglied Taschenform, so kann jede Tasche mit einem feuerfesten Geflechtmantel versehen sein.If the dust filter element has the shape of a pocket, each pocket can be provided with a fire-proof braid be provided.
