Description

Vorrichtung zum Mischen von staubförmigem oder pulverförmigem Gut Es sind Verfahren und Vorrichtungen zum Mischen von staubförmigem und pulver@ förmigem Gut bekannt, bei dem das in einen flüssigkeitsähnlichen Zustand versetzte Gut in besonderen innerhalb des Gutbehälters angeordneten Steigrohren durch Preßluft emporgetragen und über den oberen Rand dieser Steigrohre zum Überfließen gebracht wird.Device for mixing dusty or powdery material There are methods and devices for mixing powdery and powdery Well known, in which the good in a liquid-like state in special riser pipes arranged within the material container are carried upwards by compressed air and is made to overflow over the top of these risers.

Ein derartiges Mischverfahren kann auch so durchgeführt werden, daß die innerhalb des Mischbehälters angeordnet, Steigrohre in ein besonderes Mischgefäß leinmünden, in das das zu mischende Gut einläuft und so vor dem Rücklauf in den eigentlichen Mischbehälter innig gemischt wird. Such a mixing process can also be carried out so that which are arranged inside the mixing vessel, riser pipes in a special mixing vessel open into which the material to be mixed flows and so before it is returned to the actual mixing container is intimately mixed.

Die Erfahrung hat nun beim Mischen von pulverförmigem oder staubförmigem Gut, das mittels Preßluft in im Gutbehälter angeordnetzen Steigrohren emporgetragen und zum Überfließen gebracht wird, gelehrt, daß namentlich bei größeren Mischbehältern mit mehr, erden hundert Tonnen Inhalt die Steigrohre sehr starken Beanspruchungen ausgesetzt sind, die infolge der dauernden Bewegung des Behälterinhalts. ausgelöst werden. The experience now has when mixing powdery or dusty Well, that is carried up by means of compressed air in riser pipes arranged in the material container and is made to overflow, taught that especially with larger mixing containers with more, a hundred tons of content earth the riser pipes under very heavy loads are exposed as a result of the constant movement of the container contents. triggered will.

Abgesehen davon standen bei dem bisherigen Mischverfahren die Steigrohr im Innern des Behälters, und zwar im Gut selbst. Apart from that, the riser pipes were used in the previous mixing process inside the container, in the good itself.

Die Folge davon war, daß sich manche Rohre verstopften und infolgedessen nicht arbeiteten, ohne daß sie dabei von außen überwacht werden konnten und ohne daß es infolgedessen möglich war, diesen Nachteil zu beseitigen.The consequence of this was that some pipes became clogged and as a result did not work without and without being monitored from the outside that, as a result, it was possible to overcome this disadvantage.

Besonders schwerwiegend fiel blei dem bisherigen Mischverfahren noch außerdem ins Gewicht, daß eine Entnahme des Mischgutes aus verschiedenen Hoben schwierig war. Die im Mischbehälter von oben frei hineinragenden Steigrohre mit daran befestigten Mischdüsen wurden durch die Kraft der bei beginnender Auflockerung emporgedrückten Gutmassen leicht abgebogen, so daß das Gut nicht immer aus den einzelnen Gutschichten entnommen werden konnte. Für eine gute und schnelle Mischung ist es aber gerade wichtig, das Gut aus verschiedenen Höhenlagen des Behälters zu entnehmen und zwecks inniger Mischung zusammenzubringen. The previous mixing process was particularly serious also significant that it is difficult to remove the mixed material from different lifts was. The riser pipes protruding freely from above in the mixing container are attached to them Mixing nozzles were pushed up by the force of the loosening up Good weights slightly bent so that the good does not always consist of the individual good layers could be taken. For a good and quick mix it is just enough important, to remove the goods from different heights of the container and for the purpose of more intimate Bringing Mixture Together.

Die geschilderten Nachteile werden durch die Erfindung beseitigt, Das Mischgut wird nicht mehr, wie bisher, mittels im Behält angeordneter Steigrohre im Kreislauf inner halb des Mischbehälters selbst geführt. Die Steigrohr und die Mischdüsen sind vielmehr außerhalb des Mischbehälters und ganz oder teilweise in besonderen Gutrohren angeordnet, die mit dem Innern des Mischbehälters durch Gutzulauföffnungen in Verbindung stehen. Damit das Gut aus verschiedenen Schichten in die Gutrohre einlaufen kann, weisen die Gutzulauföffnungen in der Wandung des Mischbehälters verschiedene Höhenlagen auf. Innerhalb der aus den Gutrohren herausführenden und frei liegenden Steigrohre können Zwischenstücke aus durchsichtigem Werkstoff angeordnet sein, um den Durchgang des Gutes und damit das einwandfreie Arbeiten der Anlage beobachten zu können. The disadvantages outlined are eliminated by the invention, The mix is no longer, as before, by means of riser pipes arranged in the container out in the circuit within the mixing tank itself. The riser and the Mixing nozzles are rather outside the mixing container and wholly or partially in special material pipes are arranged, which are connected to the inside of the mixing container through material inlet openings stay in contact. So that the good from different layers in the good pipes can run in, have the material inlet openings in the wall of the mixing container different altitudes. Within the leading out of the good pipes and exposed riser pipes can be arranged with intermediate pieces made of transparent material to ensure the passage of the goods and thus the proper functioning of the system to be able to observe.

Die Zeichnung veranschaulicht ein Ausführungsbeispiel einer Vorrichtung zur Ausübung des Verfahrens. The drawing illustrates an embodiment of a device to carry out the procedure.

Abb. i zeigt einen Längsschnitt nach der Linie AB in Abb. 2, Abb. 2 einen Querschnitt nach der Linie C-D in Abb. I, Abb. 3 einen Querschnitt nach der Linie E-F in Abb. I und Abb. 4 einen Querschnitt nach der Linie OH in Abb. I. Fig. I shows a longitudinal section along the line AB in Fig. 2, Fig. 2 shows a cross section along the line C-D in Fig. I, Fig. 3 shows a cross section the line E-F in Fig. I and Fig. 4 a cross-section along the line OH in Fig. I.

Der eigentliche Mischbehälter I ist wie bekannt ausgebildet und im oberen Teil mit einem Zulauf 2 versehen. Das gemischte Gut wird durch den Auslauf 3 abgeführt. Außerhalb des Mischbehälters 1 sind mehrere Gutrohre 4 angeordnet, deren oberes Ende jteweils durch eine Öffnung 5 bzw. 6 mit dem Mischbehälter I in Verbindung steht. Im unteren Teil dieses Mischbehälters 1 sind diese Gutrohre als Mischstutzen 7 ausgebildet. The actual mixing container I is designed as known and in the Provided the upper part with an inlet 2. The mixed goods are discharged through the outlet 3 discharged. Outside the mixing container 1, several material pipes 4 are arranged, the upper end of which in each case through an opening 5 or 6 with the mixing container I in Connection. In the lower part of this mixing container 1, these good pipes are as Mixing nozzle 7 formed.

Innerhalb dieser Gutrohre 4 bzw. Mischstutzen7 bzw. in sie hineinragend liegen Steigrohre 8, deren unteres Ende mit einer Mischdüse 9 versehen ist. Das obene Ende dieser Steigrohre 8 mündet in den oberen Teil des Mischbehälters 1 ein. Die unteren Enden der Gutrohre 4 sind geschlossen, so daß das Gut zwangsläufig aus verschiedenen Höhenlagen in die Mischrohre einläuft und mittels der Steigrohre 8 in den oberen Teil des Mischbehälters 1 zurückgeführt wird.Within these good pipes 4 or mixing nozzles 7 or protruding into them are riser pipes 8, the lower end of which is provided with a mixing nozzle 9. That The upper end of this riser pipe 8 opens into the upper part of the mixing container 1. The lower ends of the Gutrohre 4 are closed, so that the material inevitably from runs into the mixing pipes at different heights and by means of the riser pipes 8 is returned to the upper part of the mixing container 1.

Der Boden 10 des Mischbehälters 1 besteht in bekannter Weise aus porösem Baustoff, so daß die in den darunterliegenden Hohlraum 11 eintretende Preßluft hauchartig in den Behälter selbst zur Auflockerung des Gutes eingeleitet wird. Ebenso ist auch unter den einzelnen Mischdüsen g eine Platte aus derartigem porösem Stoff angeordnet, durch die ebenfalls die Preßluft in fein verteiltem Zustande eingeblasen wird, um das Gut in den Gutrohren 4 aufzulockern.The bottom 10 of the mixing container 1 is made of porous material in a known manner Building material, so that the compressed air entering the cavity 11 underneath is like a breath is introduced into the container itself to loosen the material. Likewise is also a plate made of such a porous material is arranged under the individual mixing nozzles g, through which the compressed air is also blown in in a finely divided state to to loosen the material in the material pipes 4.

Die Wirkungsweise des Verfahrens ist folgende: Sobald das Gut durch den Zulauf 2 in den Mischbehälter 1 einläuft, wird es auch durch die entsprechenden Öffnungen 5 und 6 in die Gutrohre 4 bzw. in die Mischstutzen 7 eintreten. The mode of action of the process is as follows: As soon as the good is through the inlet 2 runs into the mixing container 1, it is also through the corresponding Openings 5 and 6 enter the material pipes 4 and the mixing nozzle 7, respectively.

Sobald nun die Preßluft durch das Rohr 12 in die Mischdüse 9 eingeblasen wird, wird auch das in diesen Gutrobren 4 lagernde Gut innerhalb der Steigrohre 8 emporgetragen und in den oberen Teil des Mischbehälters zurückgeführt. Da die Eintrittsöffnungen 5 und 6 zu den Gutrohren 4 bzw. zum Mischstutzen 7 in verschiedenen Höhlen liegen, wird der gesamte Inhalt innig gemischt. As soon as the compressed air is blown through the pipe 12 into the mixing nozzle 9 is, the goods stored in these Gutrobren 4 will be within the riser pipes 8 carried up and returned to the upper part of the mixing container. Since the Inlet openings 5 and 6 to the material pipes 4 or to the mixing nozzle 7 in different If there are caves, the entire contents are intimately mixed.
