Abstract

During blasting work, large quantities of blasting material (granules, glass beads, slag and sand) together with residues of blasted colour coating are projected over a large area after impact with the surface being blasted. This results in the pollution of large areas of the surrounding environment. The large quantities of dust produced cause problems for the population over a much wider area. The inventive suction device prevents blasting material, dust and liquids from escaping from the blasting site and the area immediately surrounding the blast nozzle into the environment during blasting work. A second suction system which functions separately allows the device, with its integrated blast pressure nozzle, to hold itself steady automatically, even in extreme working positions, e.g., overhead, hereby relieving the operator of this task, and can still be moved laterally in any direction. The high suction capacity of the device ensures that the blasting material or liquids which rebound or are projected off of the surface during blasting work are extracted without leaving a residue and collected in containers. The inventive suction device can also be used for drying the expansion joints of concrete slabs etc. and prevents the pollution of the environment with residues of dust, joint material and chemical material.

Description

Mit der neuen Erfindung werden wahrend Strahlarbeiten weggeschleudeπe Staub- und Strahlpaπikel. sowie Flüssigkeiten und abgestrahlte Beschichtungsreste direkt aus dem Wirkungs- und Nahbereich der Strahldruckdusen oder Stemm- und Bohrgeraten von allen Seiten gleichzeiüg dem Sirahldruck entsprechend abgesaugt und in Behalter geleitetWith the new invention, dust and jet particles are thrown away during blasting work. as well as liquids and blasted coating residues are extracted directly from the effective and close range of the jet pressure nozzles or mortising and drilling devices from all sides according to the Sirahl pressure and directed into containers
Gleichzeitig wird durch ein getrennt wirkendes zweites Absaugsystem ber den Hohlraum (7a) einer Doppelwandschutzhaube (7) mit integrierter Strahldruckduse (1) die Doppelwandschutzhaube (7) an die Arbeitsfläche mit dem gesamten Umfang angesaugt, so daß auch bei "Uberkopfpo- sitionen ' sich die Doppelwandschutzhaube (7) selber festhalt aber mit Hilfe von Stützrollen (13) oder -kugeln in alle Richtungen seitlich verschieben laßt Weil die Saugleistung des zweiten Absaugsystems sich ebenfalls dem Strahldruck automatisch anpaßt, wird ein Abheben der Doppelwandschutzhaube (7) und ein entweichen von eventuellen Ab- strahlresten mit Sicherheit ausgeschlossenAt the same time, the double-walled protective hood (7) is sucked into the working area with the entire circumference through a separate second suction system via the cavity (7a) of a double-walled protective hood (7) with an integrated jet pressure nozzle (1), so that even in "overhead positions" Double wall protection hood (7) itself holds firmly but can be moved laterally in all directions with the help of support rollers (13) or balls Because the suction power of the second suction system also automatically adjusts to the jet pressure, lifting the double wall protection hood (7) and escaping any Ab - jet residues are definitely excluded
Die sehr hohe Absaugleistung aus dem Innenraum der Doppelwandschutzhaube (7) wird dadurch erreicht, weil das erste Absaugsystem über mehrere auf der gesamten Oberfläche der Doppelwandschutzhaube (7) verteilt angeordnete und bis in den Innenraum durchgesteckte Saugrohrstutzen (4) direkt rund um den Strahlbereich von allen Seiten gleichzeitig mit Hilfe von Saugturbinen wirken kannThe very high suction power from the interior of the double-wall protection hood (7) is achieved because the first suction system has multiple suction pipe sockets (4) that are distributed over the entire surface of the double-wall protection hood (7) and pushed all the way into the interior, all around the jet area Pages can act simultaneously with the help of suction turbines
Die Saugrohrstutzen (4 j 5) sind den getrennten Absaugsystemen entsprechend, über Sammelsaugrohrleitungen (6) mit geschlossenen Auf angbehaltem verbunden Die Auf- fangbehalter sind mit Endschalter ausgerüstet, die ein Abschalten des Strahldruckes der Kompressoren bewirken, aber einen Weiterbetneb der Absaugung gewährleisten könnenThe suction pipe sockets (4 j 5) are connected to the separate suction systems, via collective suction pipes (6) with closed receptacles. The collecting receptacles are equipped with limit switches, which switch off the jet pressure of the compressors, but can ensure that the suction continues
Eine Art der Ausführung wird wie folgt beschrieben. Die Stahldruckduse (1) befindet sich m einem Mantelsaugrohr 13) welches an der Dusenoffnungsseite offen und am anderen Ende verschlossen, sowie mit Saugrohrstutzen (12) für Saugleitungsanschlusse versehen istOne type of execution is described as follows. The steel pressure nozzle (1) is located in a jacket suction pipe 13) which is open on the nozzle opening side and closed at the other end, and is provided with a suction pipe socket (12) for suction line connections
Die Stranldruckduse (1) mit Manielsaugrohr (3) ist in den Innenraum einer Doppelwandschutzhaube (7) eingeführt und hohenverstellbar. gelenkig, verschiebbar oder starr im Durchfuhrungsbereich der Doppelwand (2) befestigtThe line pressure nozzle (1) with a manual suction pipe (3) is inserted into the interior of a double-walled protective hood (7) and can be adjusted in height. articulated, displaceable or rigid in the lead-through area of the double wall (2)
Die Doppel andschutzhaube (7) besteht aus einer Doppelwand, deren Hohlraum durch Distanzstege zwischen den Wanden gebildet wird Auf der äußeren Oberflache der Doppelwandschutzhaube (7) sind mehrere Saugrohrstutzen (51 über dem Umfang verteilt angebracht, die mit einer eigenen Sammelsaugleitung (6; miteinander und zusatzlich mit einem separaten Saugaggregat bzw Saugturbine, sowie Auffangbehaltem verbunden sindThe double and protection hood (7) consists of a double wall, the cavity of which is formed by spacers between the walls. On the outer surface of the double wall protection hood (7) there are several intake manifold sockets (51 distributed over the circumference, which have their own collective suction line (6; with each other and are additionally connected to a separate suction unit or suction turbine, as well as collecting container
Der untere Rand der Doppelwandschutzhaube (7) weist einen über dem gesamten Umfang verlaufenden breiten Schlitz auf, der durch den Hohlraum (7a) der Doppelwand entstanden ist und bildet einen Saugkanal (8) Einseitig oder beidseitig des Saugkanals (8) befinden sich eine oder mehrere Abdichύeisten (91 aus elastischem Material WO 99/37443 _ ∑ _ PCT/DE99/00145The lower edge of the double-wall protection hood (7) has a wide slot that extends over the entire circumference, which is created by the cavity (7a) of the double wall and forms a suction channel (8) on one or both sides of the suction channel (8) there are one or more Sealing (91 made of elastic material WO 99/37443 _ ∑ _ PCT / DE99 / 00145
Am äußeren Umfang des Saugkanals (8) sind Stutzrollen (13) befestigt, die ein Verschieben trotz starker Ansaugung 60 ermöglichen Für das zweite Absaugsystem sind mehrere über die gesamte Oberfläche verteilt angeordnete Saugrohrstutzen (4) durch die Doppelwand bis in den Innenraum der Doppelwandschutzhaube (7) hineinragend starr angebracht. Diese Saugrohrstutzen (4) sind ebenfalls mit eigenen Sam- 65 melsaugleitungen (6), eigener Saugturbine und Auffangbehaltem verbunden.Support rollers (13) are attached to the outer circumference of the suction channel (8), which enable displacement despite strong suction 60. For the second suction system, several suction pipe sockets (4) distributed over the entire surface are through the double wall into the interior of the double wall protective hood (7 ) protruding rigidly attached. These intake manifolds (4) are also connected to their own common suction lines (6), their own suction turbine and collecting container.
An der Wandinnenseite der Doppelwandschutzhaube (7) sind in verschiedenen Positionen und Richtungen umlaufend schräg und gerade angeordnete Prall- bzw. Leitplatten (10) oder Profile befestigt. Vorteilhafter Weise können die Prall- bzw Leitplatten (10) spiralförmig oder rippenartig positioniert sein.On the inside of the double wall protective hood (7), diagonally and straightly arranged baffle or guide plates (10) or profiles are attached in various positions and directions. The baffle or guide plates (10) can advantageously be positioned in a spiral or rib-like manner.
Die Prall- und Leitplatten (10) oder Profile bewirken ein Abbremsen des auf der Oberflache aufgetroffenen und abge- prallten Strahldruckes, sowie ein Ableiten und direktes Zufuhren des Strahlgutes oder Flüssigkeiten zu den nachsthe- genden Saugτonrstutzen (4) Die im Nahbereich des Saugkanals (8) gelenkig befestigten und mit Federkraft in Position gehaltene Prall- und Leitplatten (10) oder Profile verhindern, daß evtl zu große Strahlgutmengen bei einer zu starken Neigung der Strahldruckduse (1) ungehindert erst im Saugkanal (8) des anderen Absaugsystems abgesaugt werden.The baffle and baffle plates (10) or profiles slow down the jet pressure that has hit and rebounded on the surface, as well as directing and direct supply of the blasting material or liquids to the following suction nozzles (4). The in the vicinity of the suction channel (8 ) articulated and baffle plates and baffles (10) or profiles that are held in position by spring force prevent excessive amounts of blasting material from being sucked unhindered in the suction channel (8) of the other suction system if the blasting pressure nozzle (1) is inclined too much.
