Bei einer anderen Ausführungsform der Erfindung erfolgt die Regelung des Strahldrucks durch Veränderung der Luftzufuhr zur Druckluft-Bildung, wobei gleichzeitig die Zuführung des Trockeneisgranulats verändert wird.In another embodiment of the invention the regulation of the jet pressure by changing the Air supply for the formation of compressed air, at the same time the Feeding the dry ice granules is changed.
Auch kann der Strahldruck an der Strahlpistole und die Fördermenge des CO₂-Trockeneisgranulats durch getrennte, jedoch in regelbarer Abhängigkeit voneinander arbeitende Regler eingestellt werden.Also the blasting pressure on the blasting gun and the Flow rate of the CO₂ dry ice granules through separate, however working in controllable interdependencies Controller can be set.
Dabei kann der Strahldruck bzw. die Strahlmenge auch direkt an der Strahlpistole über eine elektrische Potentiometerregelung oder eine pneumatische Regelung mit jeweils gesonderter Leitung vom Gerät zur Venturidüsen- Pistole geregelt werden. The jet pressure or the amount of jet can also be used directly on the blasting gun via an electrical Potentiometer control or a pneumatic control with each separate line from the device to the Venturi nozzle Gun to be regulated.
Wichtig ist die Ausbildung der Erfindung in einer Vorrichtung zur Durchführung des erfindungsgemäßen Verfahrens mit einer am freien Ende eines Zufuhrschlauchs angeordneten Strahlpistole, einem CO₂-Trockeneis-Einfüll- Trichter und einer Förderschnecke, an dessen Mündung sowie einem mit Druckluft betriebenen Luftmotor zu deren Antrieb und einem davon angetriebenen nachgeschalteten Rührwerk, wobei der Zufuhrschlauch zur Strahlpistole sowohl eine Druckluftleitung als auch eine gesonderte Leitung für die Zufuhr von CO₂-Trockeneisgranulat aufweist, welche an ihrem freien Ende an der Strahlpistole in eine Kammer mündet, die mittels der Druckluftleitung unter Unterdruck gesetzt wird, dessen dahin angesaugtes CO₂-Trockeneisgranulat aus der Strahlpistole auf die zu behandelnde bzw. zu reinigende Oberfläche ausstrahlbar ist.It is important to form the invention in one Device for performing the invention Procedure with one at the free end of a supply hose arranged blasting gun, a CO₂ dry ice filler Funnel and a screw conveyor at its mouth and an air motor operated with compressed air Drive and a downstream driven by it Agitator, taking the supply hose to the blasting gun both a compressed air line and a separate one Line for the supply of CO₂ dry ice granules which has at its free end on the Jet gun opens into a chamber, which by means of the Compressed air line is placed under negative pressure, the CO₂ dry ice granules sucked in from the Blasting gun on the one to be treated or cleaned Surface can be emitted.
Dabei kann bevorzugt die CO₂-Trockeneismenge von dem Bedienungsgriff der Strahlpistole aus durch den gleichzeitigen Antrieb des Luftmotors und der Förderschnecke mittels des Druckluftkompressors gemeinsam regulierbar oder die Druckluftmenge und das CO₂- Trockeneisgranulat mit der Förderschnecke von dem Bedienungsgriff der Strahlpistole aus getrennt regulierbar sein.It can preferably the amount of CO₂ dry ice Operating handle of the blasting gun from through the simultaneous drive of the air motor and the Screw conveyor together using the air compressor adjustable or the amount of compressed air and the CO₂ Dry ice granulate with the screw conveyor from that Operating handle of the blasting gun separated from be adjustable.
Weitere Verbesserungen der Erfindung ergeben sich aus den Merkmalen der Ansprüche 9 bis 11.Further improvements of the invention result from the Features of claims 9 to 11.

Gemäß Fig. 1 wird feste Kohlensäure (CO₂) in Form hochverdichteter Körnchen als Trockeneisgranulat 2 in einen Trockeneis-Einfüll-Trichter 1 eingefüllt, welches in dem Trockeneis-Einfüll-Trichter 1 einen Vorrat 3 bildet und auf einer Seitenwandschräge 44 unter Schwerkraftwirkung, gegebenenfalls unter einer Rüttel- oder Klopfvibration mittels eines Klopfers 10 bzw. Klopfen auf den Trockeneis-Einfüll-Trichter 1 in einstellbaren Zeitabständen ein gleichmäßiges Nachrutschen des Trockeneisgranulats 2 zu gewährleisten.Referring to FIG. 1 solid carbon dioxide (CO₂) in the form is filled in high density granules as dry granules 2 in a dry ice required hopper 1, forming in the dry ice required hopper 1 a reservoir 3 and a side wall slope 44 under gravity, optionally with to ensure a shaking or knocking vibration by means of a beater 10 or tapping on the dry ice required hopper 1 in adjustable time intervals an even sloughing of the dry granules. 2
Das Trockeneisgranulat 2 gelangt durch die Mündung 9 des Trockeneis-Einfüll-Trichters 1 in eine Förderschnecke 5, welche über einen pneumatisch betriebenen Luftmotor 16 angetrieben wird, so daß somit das Trockeneisgranulat in den Trockeneisgranulatschlauch 6 gefördert wird. Der Luftmotor 16 treibt gleichzeitig ein Rührwerk 4, welches die CO₂-Körnchen durch seine Rührbewegung vor dem Verklumpen schützt.The dry ice granules 2 pass through the mouth 9 of the dry ice filling funnel 1 into a screw conveyor 5 , which is driven by a pneumatically operated air motor 16 , so that the dry ice granules are conveyed into the dry ice granulate hose 6 . The air motor 16 simultaneously drives an agitator 4 , which protects the CO₂ granules from clumping by its stirring movement.
Der in einer Kammer 17 einer Strahlpistole 11 erzeugte Unterdruck saugt das CO₂-Granulat an und wird durch die von einem Kompressor eingespeiste Druckluft durch eine Düse 12 der Strahlpistole 11 auf die zu behandelnde Oberfläche gestrahlt.The vacuum generated in a chamber 17 of a blasting gun 11 sucks in the CO₂ granules and is blasted by the compressed air fed in by a compressor through a nozzle 12 of the blasting gun 11 onto the surface to be treated.
An der Vorderseite des Gerätes ist eine Anzeigetafel 13 angebracht, hinter der sich eine Pneumatiksteuerung 45 befindet. Auf einer Anzeigetafel 13 (Fig. 3) befinden sich ein Manometer 18, welches den Strahldruck anzeigt, zwischen 3-20 bar. Ein Strahldruckregler 19 läßt eine Variation der Aufprallintensität des CO₂-Granulats in diesem Bereich zu. Ein weiteres Manometer 21 zeigt den Trockeneisgranulatverbrauch pro Stunde an, welcher sich ebenfalls durch den Förderdruckregler 22 in einem Bereich von 20 Kilogramm bis 80 Kilogramm pro Stunde variieren läßt. Dieser Effekt wird durch Drosselung der Luftzufuhr zum Luftmotor 16 erreicht, welcher die Umdrehung der Förderschnecke 5 beeinflußt. Die gewünschte Agressivität des körnigen CO₂-Pelletstrahls wird durch austauschbare Luftfinger 23-31 sowie zugehörige Strahldüsen 32-40 erzielt. Die einzelnen Luftfinger 23-31 unterscheiden sich jeweils in Luftdurchsatzkapazität. A display panel 13 is attached to the front of the device, behind which there is a pneumatic control 45 . On a display panel 13 ( FIG. 3) there is a manometer 18 , which shows the jet pressure, between 3-20 bar. A jet pressure regulator 19 allows a variation in the impact intensity of the CO₂ granulate in this area. Another manometer 21 shows the dry ice granulate consumption per hour, which can also be varied by the delivery pressure regulator 22 in a range from 20 kg to 80 kg per hour. This effect is achieved by throttling the air supply to the air motor 16 , which influences the rotation of the screw conveyor 5 . The desired aggressiveness of the granular CO₂ pellet jet is achieved by replaceable air fingers 23-31 and associated jet nozzles 32-40 . The individual air fingers 23-31 each differ in air throughput capacity.
Der Bediener hat die Möglichkeit sowohl am Gerät als auch an der Strahlpistole 11 Strahldruck und Fördermenge über zwei Regler 14-15 (Fig. 6) zu verändern. Der entscheidende Vorteil, den diese Neuerung mit sich bringt, ist ein bedeutend geringerer Trockeneisverbrauch. Da der Bediener während des Strahlens der verschiedenen Oberflächen die notwendige Trockeneismenge sowie Druckluftmenge regulieren kann. Das bedeutet, daß man nur soviel Trockeneis verstrahlt, wie für die zu reinigende Fläche notwendig ist.The operator has the option of changing the jet pressure and delivery rate both on the device and on the blasting gun 11 using two controllers 14-15 ( FIG. 6). The decisive advantage that this innovation brings is a significantly lower dry ice consumption. Because the operator can regulate the required amount of dry ice and compressed air while blasting the various surfaces. This means that only as much dry ice is blasted as is necessary for the surface to be cleaned.
