Description

Bezeichnungdescription
Druckgas-betriebener,filterloser Industriestaubsauger, geeignet für den Anschluß an eine vorhandene Absaug-und Filteranlage.Pressurized gas operated, filterless industrial vacuum cleaner, suitable for connection to an existing suction and filter system.
Stand der TechnikState of the art
In Industriebetrieben setzt man zum Staubsaugen meist bewegliche Induεtriestaubsauger ein. Gelegentlich sind auch stationäre Staubsauger installiert, die meist an einer längeren Saugleitung sitzen und mehrere 'Steckdosen' für Staubsaugwerkzeuge haben. Beide Staubsauger verfügen über eigene Filter, die periodisch gereinigt und erneuert werden müssen. Ein Sauggebläse - auf der Reinluftseite, d.h.nach dem Filter arbeitend - erzeugt den erforderlichen Saugunterdruck und die Absaugmenge.In industrial companies, portable industrial vacuum cleaners are usually used for vacuuming. Occasionally, stationary vacuum cleaners are also installed, which are usually located on a longer suction line and have several 'sockets' for vacuum cleaning tools. Both vacuum cleaners have their own filters, which have to be cleaned and replaced periodically. A suction fan - on the clean air side, i.e. working after the filter - generates the required suction vacuum and the amount of suction.
Nachteile der Industriestaubsauger sind deren limitierte Filterfläche, die zu einem frühen Abreinigen und Wechsel zwingt, der große Aufwand vor Ort, einen Staubsauger zu beschaffen und diesen nach Gebrauch gereinigt wieder weiterzugeben, die Sperrigkeit dieser Geräte und die damit verbundenen Behinderungen.Disadvantages of industrial vacuum cleaners are their limited filter area, which means that they have to be cleaned and replaced early, the great effort on site to get a vacuum cleaner and pass it on again after use, the bulkiness of these devices and the associated disabilities.
Zudem bläst der Staubsauger wieder Luft ab und sorgt so für Luftturbulenzen, die Stäube aufwirbeln können. Diese Argumente und die meist geringe Zahl an vorhandenen Geräten in einem Betrieb erklären die oft mangelnde Akzeptanz des Industriestaubsaugers in den Betrieben.In addition, the vacuum cleaner blows off air again, creating air turbulence that can stir up dust. These arguments and the usually small number of existing devices in a company explain the often insufficient acceptance of the industrial vacuum cleaner in the company.
Aufgabe der Erfindung ist es, die genannten Nachteile zu vermeiden und ein Gerät zu schaffen, das klein und preiswert ist, und das amThe object of the invention is to avoid the disadvantages mentioned and to create a device that is small and inexpensive, and that
ORIGINALUNTERLAGEN Ort des Bedarfs stets verfügbar ist.ORIGINAL DOCUMENTS Place of need is always available.
Die Lösung der Aufgabe wird erreicht durch Verzicht des Staubsaugers auf ein eigenes Filter und stattdessen die Mitbenutzung des Fil¬ ters in der häufig vorhandenen Abluft-u.Filteranlage für die Luft-Absaugung an Maschinen und Arbeitsplätzen, d.h. durch das Anschließen an ein solches Absaugsystem (wenn vorhanden) , durch den Einsatz einer Drucklufttreibdüse anstatt eines Saugventilators, durch eine Ruhevorrichtung für das Saugwerkzeug, bei dem im Ruhezustand des Werkzeugs die Treibdüse abgestellt wird. Vice versa beginnt mit dem Entnehmen des Werkzeugs das Saugen. Eine Vorrichtung dieser Art ist beschrieben in G 94 01 201.6The solution to the problem is achieved by dispensing with the vacuum cleaner on its own filter and instead using the filter in the frequently available exhaust air and filter system for air extraction at machines and workplaces, i.e. by connecting to such a suction system (if present), by using a compressed air driving nozzle instead of a suction fan, by a resting device for the suction tool, in which the driving nozzle is switched off when the tool is at rest. Vice versa starts vacuuming when the tool is removed. A device of this type is described in G 94 01 201.6
Die folgenden Vorteile sind mit der erfindungsgemäßen Bauweise eines Industrie- Staubsäugers verbunden: - Er steht immer zur Verfügung.The following advantages are associated with the construction of an industrial vacuum cleaner according to the invention: - It is always available.
- Er ist klein und an der Maschine /am Arbeitsplatz so befestigt, daß er nicht stört.- It is small and attached to the machine / work place so that it does not interfere.
- Sein Filter muß nicht gereinigt werden, denn er hat kein eigenes Filter. Die im Betrieb vorhandene Abluft- Filteranlage ist für vergleichsweise sehr große Luft¬ mengen ausgelegt und wird durch ihn kaum mehrbelastet.- Its filter does not have to be cleaned, because it does not have its own filter. The exhaust air filter system in operation is designed for comparatively very large amounts of air and is hardly loaded by it.
- Das Filter der Abluft-Filteranlage wird automatisch gereinigt. Der Benutzer des Staubsaugers hat damit nichts zu tun. - Da die örtliche Staubsaugmenge sehr klein ist -gemessen an der Kapazität der Abluftfilteranlage, können problem¬ los mehrere Staubsauger angeschlossen werden.- The filter of the exhaust air filter system is cleaned automatically. The user of the vacuum cleaner has nothing to do with it. - Since the local amount of vacuum is very small - measured by the capacity of the exhaust air filter system, several vacuum cleaners can be connected without any problems.
- Saugwerkzeuge können jederzeit nachinstalliert werden, - Die Filterqualität einer Abluftanlage ist meist höher als bei Industriestaubsaugern: bessere Reinigung.- Suction tools can be installed at any time, - The filter quality of an exhaust air system is usually higher than that of industrial vacuum cleaners: better cleaning.
- Die Kosten pro Staubsauger-Einheit sind geringer.- The cost per vacuum cleaner unit is lower.
- Das System ist ohne großen Aufwand auch für besondere Hygiene-und Ex-Anforderungen adaptierbar. - Vorabscheider zum Zweck der Entlastung der Filter¬ anlage und der Rohrleitung oder zur Gewinnung des Saugguts sind unproblematisch und stets nachrüstbar.- The system can also be adapted to special hygiene and Ex requirements with little effort. - Pre-separators for the purpose of relieving the strain on the filter system and the pipeline or for extracting the suction material are unproblematic and can always be retrofitted.
In einem bevorzugten Ausführungsbeispiel wird in Fig.l eine erfindungsgemäße Vorrichtung(20) in gezeigt. Die Treibdüse ist hier eine Ringsspaltdüse(1) . Die Druckluft strömt über den Spalt(2) der Düse(l) in den Förderquerschnitt(3) ein, und zieht dabei Luft aus dem stromaufwärts liegenden Rohr(4) in Förderrichtung mit. Die Zu-bzw.Abschaltung des Druckluftventils(5) geschieht mittels des Ventilstößels (6) . Wenn das Saugrohr(20.1) in die Öffnung(7.1) der Werkzeugaufnahme(7) eingeschoben wird, wird gleichzeitig der Ventilstößel (6) des Ventils (5) gedrückt und der Druckluftstrom wird unterbrochen. Die Saugöffnung(8) wird weitestgehend geschlossen.In a preferred embodiment, a device (20) according to the invention is shown in FIG. The driving nozzle here is an annular gap nozzle (1). The compressed air flows through the gap (2) of the nozzle (l) into the conveying cross section (3), drawing air from the upstream pipe (4) in the conveying direction. The compressed air valve (5) is switched on and off by means of the valve tappet (6). If the suction pipe (20.1) is inserted into the opening (7.1) of the tool holder (7), the valve tappet (6) of the valve (5) is pressed at the same time and the compressed air flow is interrupted. The suction opening (8) is largely closed.
Das Saugwerkzeug(20) wird an der Absaugrohrleitung(9) so angeschlossen, daß bei Betrieb dieser in Fließrichtung eingeblasen wird. The suction tool (20) is connected to the suction pipe (9) in such a way that it is blown in in the direction of flow during operation.
