Abstract

Continuous drum sand blasting device where the components to be cleaned pass through the drum in its longitudinal direction and are blasted with the aid of thrower wheels. The drum, which is inclined in the longitudinal direction, is supported so that it can pivot about its axis between two angle positions. It has at least one upper casing opening through which the thrower wheels throw the cleaning medium on the material to be cleaned in the drum. The rear part of the drum is in the form of a filter drum to separate out the cleaning medium.

Description

Fließtrommel zur kontinuierlichen Bestrahlung von Guß stücken mit Hilfe von Schleuderrädern Es sind Bließtrommel-Bestrahlungsvorrichtungen bekannt, bei denen die zu putzenden'lleile durch die waagerechte, in Drehung versetzte Trommel mit Hilfe innerer Schraubengänge hindurchbewegt und dabei durch Schleuderräder bestrahlt werden. Die Schleuderräder befinden sich dabei an den Stirnseiten der Trommel außerhalb derselben und die Wurfstrahlen gelangen durch stirnseitige Trommel öffnungen zu dem in der Trommel liegenden Putzgut. Flow drum for continuous irradiation of cast pieces with With the help of centrifugal wheels Blasting drum irradiation devices are known, where the parts to be cleaned by the horizontal drum set in rotation moved through with the help of internal screw threads and irradiated by centrifugal wheels will. The centrifugal wheels are located on the front of the drum outside the same and the jets get through openings on the front side of the drum the items to be cleaned in the drum.

Mit Bließbandtrommeln dieser Art können jedoch sehr kleine und sehr große Teile nicht bestrahlt werden. Trotz einwandfreier Abdichtung zwischen der umlaufenden Trommel und den feststehenden, die Schleuderräder tragenden Wänden hat es sich nämlich nie ganz vermeiden lassen, daß sich hier kleine Putzgutteile festsetzen und zu Störlmgen Anlaß geben.With this type of ribbon drums, however, very small and very small large parts are not irradiated. Despite perfect sealing between the revolving drum and the fixed walls supporting the centrifugal wheels Namely, it can never be completely avoided that small items of cleaning items get stuck here and give rise to disturbances.

Große Teile ließen sich überhaupt nicht in die Trommel hineinbringen, da die Durchtrittsöffnungen durch die Schleuderräder notwendigerweise ziemlich eng sind.Large parts could not be brought into the drum at all, since the openings through the centrifugal wheels are necessarily quite narrow are.

Aufgabe der Erfindung ist es, diesen Mängeln ~abzuhelfen, so daß mittels der Fließtrommel auch wesentlich kleinere und wesentlich größere Teile bestrahlt werden können, weil ein Festsetzen kleiner Putzgutteile hier nicht möglich ist und die stirnseitigen Ein- und Auslaßöffnungen der Trommel nicht eingeengt sind.The object of the invention is to remedy these deficiencies so that by means of the flow drum also irradiates much smaller and much larger parts because it is not possible to fix small parts of the items to be cleaned and the front inlet and outlet openings of the drum are not restricted.

Erfindungsgemäß wird dies dadurch erreicht, daß die in der Lärlgsrichtung geneigte Trommel um ihre Achse zwischen zwei Winkelstellungen schwenkbar gelagert ist und wenigstens eine obere Mantelöffnung hat, durch die hindurch die Schleuderräder das Putzmittel auf das in der Trommel befindliche Putzgut werfen. Da die Schleuderräder sich oberhalb der Trommel befinden, können auch niemals Putzgutteile in die Wurfelemente der Schleuderräder fallen. Ein weiterer Vorteil der Erfindung besteht darin, daß die zu bestrahlenden rutzgutteile weniger beansprucht werden, weil die Trommel nicht umläuft, sondern, wie gesagt, nur Schwenkbewegungen ausführt und weil das Putzgut allein durch das Gefälle der geneigten Trommel durch diese hindurchwandert.According to the invention this is achieved in that the in the Lärlgsrichtung inclined drum mounted pivotably about its axis between two angular positions and has at least one upper shell opening through which the centrifugal wheels Throw the cleaning agent on the items to be cleaned in the drum. As the centrifugal wheels are located above the drum, parts of the items to be cleaned can never get into the throwing elements the spinning wheels fall. Another advantage of the invention is that the rutzgutteile to be irradiated are less stressed because the drum is not runs around, but, as I said, only executes swiveling movements and because the items to be cleaned only moves through the slope of the inclined drum through this.

Zweckmäßig ist der in der Transportrichtung des Putzgutes letzte Teil der Trommel als Siebtrommel zur Abscheidung des Putzmittels ausgebildet, so daß die Nachschaltung einer bei den bisherigen J?ließtrommel-Eestrahlungsvorrichtungen erforderlichen Abscheidetrommel entfällt.The last part in the direction of transport of the items to be cleaned is useful the drum designed as a sieve drum for separating the cleaning agent, so that the downstream installation of one of the previous J? lass drum radiation devices The necessary separating drum is not required.

Die Zeichnung zeigt ein AusfUlrungsbeispiel der Erfindung in einem senkrechten Längsschnitt (Fig. 1) und drei Trornelquerschnitten (Fig. 2-4) jeweils im Bereich des Put zstrahles.The drawing shows an exemplary embodiment of the invention in one vertical longitudinal section (Fig. 1) and three Trornel cross sections (Fig. 2-4) each in the area of the putty beam.

In einem Gehäuse 1 ist die in der Längsrichtung geneigte Fließtrommel 2 um ihre Achse zwischen den beiden Winkelstellungen nach Fig. 2 und 4 schwenkbar gelagert.In a housing 1 is the flow drum inclined in the longitudinal direction 2 can be pivoted about its axis between the two angular positions according to FIGS stored.

Fig. 3 zeigt ihre Mittelstellung. Das Putzgut 5 wird der Trommel mittels eines Transportbandes 3 über eine Rutsche 4 durch das obere Ende aufgegeben. Es wandert infolge des Gefälles der Trommel in der Längsrichtung durch diese hindurch, um die Trommel an deren unterem Ende zu verlassen.Fig. 3 shows its middle position. The cleaning item 5 is the drum by means of a conveyor belt 3 abandoned on a slide 4 through the upper end. It migrates through the drum in the longitudinal direction due to the gradient, to leave the drum at its lower end.

Es fällt dort auf ein anderes Transportband 6. enn die Trommel durch einen Antrieb 7 zwischen den Winkelstellungen nach Fig. 2 und 4 in hin- und hergehende Schwenkbewegungen versetzt wird, wird das Putzgut bei seinem Durchlauf in schonender Weise durcheinandergewürfelt und umgewälzt, so daß es yon dem Putemittelstrahl 8 eines aus dem Behälter 9 gespeisten, innerhalb des Gehäuses 1 befindlichen Schleuderrades 10 oder einer Mehrzahl solcher allseitig getroffen wird. Der Putzstrahl 8 gelangt in die Trommel 2 durch eine obere Mantelöffnung 12 der Trommel. Die Trommel2ist auf ihrer ganzen länge oder in ihrem in der Transportrichtung letzten Teil als Siebtrommel zur Abscheidung des Putzmittels ausgebildet.Dns durch die Sieböffnungen ausfallende Putzmittel wird mittels einer Schnecke 11 und eines nicht dargestellten Elevators erneut dem Behälter 9 zugeführt.There it falls onto another conveyor belt when the drum 6. falls through a drive 7 between the angular positions according to FIGS. 2 and 4 in reciprocating Pivoting movements are offset, the items to be cleaned are more gentle as they pass through In a jumbled manner and turned around, so that it is 8 a centrifugal wheel, which is fed from the container 9 and located within the housing 1 10 or a plurality of such is hit on all sides. The cleaning jet 8 arrives into the drum 2 through an upper shell opening 12 of the drum. The drum 2 is along its entire length or in its last part in the direction of transport as a sieve drum designed to separate the cleaning agent Cleaning agent is by means of a screw 11 and an elevator, not shown again supplied to the container 9.
