Eine Vorrichtung gemäss einer ersten Ausführungsform der Erfindung wird in Fig. 1 und 2 dargestellt.A device according to a first embodiment of the invention is shown in FIG Fig. 1 and 2 shown.

Die Eintrittsleitung 1 weist einen im Wesentlichen horizontalen Teil 2 auf, der mit einem Endteil 3 endet. Dieser besteht aus einer Düse 8, die mittels eines Muffenteils 9 mit der Einstrittsleitung 1 verbunden ist.The inlet line 1 has a substantially horizontal part 2, which ends with an end part 3. This consists of a nozzle 8 which is connected by means of a sleeve part 9 with the inlet line 1.

Die Düse 8 weist einen länglichen Teil 20 und einen ersten scheibenförmigen Teil 21 auf. Der Teil 20 ist zylinderförmig. Der erste scheibenförmigen Teil 21 ist scheibenförmig und mit dem Muffenteil 9 trennbar verbunden. Die Düse 8 weist einen Durchgang 22, dessen Querschnittsfläche von der Seite des Muffenteils 9 bis zur Endseite, d.h. in der Richtung des Hohlraums 5, axial abnimmt.The nozzle 8 has an elongate part 20 and a first disc-shaped part 21. The part 20 is cylindrical. The first disc-shaped part 21 is disc-shaped and separable with the sleeve part 9 connected. The nozzle 8 has a passage 22 whose cross-sectional area decreases axially from the side of the sleeve part 9 to the end side, ie in the direction of the cavity 5.

Der Muffenteil 9 weist einen länglichen zylinderförmigen Teil 23 und einen zweiten scheibenförmigen scheibenförmigen Teil 24 auf, der im Kontakt mit dem ersten scheibenförmigen Teil 21 ist. Die beiden scheibenförmigen Teile 21 und 24 haben im Wesentlichen den gleichen Durchmesser. Der Teil 23 ist mit der Eintrittsleitung 1 trennbar verbunden.The sleeve part 9 has an elongated cylindrical part 23 and a second disk-shaped disk-shaped part 24, which is in contact with the first disk-shaped part 21. The two disc-shaped parts 21 and 24 have substantially the same diameter. The part 23 is separably connected to the inlet line 1.

Der scheibenförmigen Teil 24 stützt sich auf dem Venturikörper 4. Die scheibenförmigen Teile 21 und 24 weisen Bohrungen auf, durch welche Schrauben eingefügt werden können. Somit werden die Düse 8 und der Muffenteil 9 gleichzeitig miteinander und mit dem Venturikörper 4 trennbar verbunden.The disc-shaped part 24 is supported on the Venturi body 4. The disc-shaped parts 21 and 24 have holes through which screws can be inserted. Thus, the nozzle 8 and the sleeve part 9 are simultaneously connected to each other and separable with the Venturi body 4.

Der Venturikörper 4 ist im Allgemeinen zylinderförmig. Auf einer Seite besitzt er ein Einlassloch zur Aufnahme des länglichen Teils 20 der Düse 8. Der Einlassloch mündet in den Hohlraum 5 des Venturikörpers 4 und hat im Wesentlichen die selbe Länge wie der längliche Teil 20 der Düse 8. In der dem Einlassloch abgewandten Seite des Hohlraums 5, befindet sich ein Auslassloch in der die Austrittsleitung 7 gelagert ist.The venturi 4 is generally cylindrical. On one side it has an inlet hole for receiving the elongated part 20 of the nozzle 8. The inlet hole opens into the cavity 5 of the venturi body 4 and has substantially the same length as the elongated part 20 of the nozzle 8. In the side facing away from the inlet hole Cavity 5, there is an outlet hole in which the outlet conduit 7 is mounted.

Der Hohlraum 5 ist zylinderförmig und seine Abmessungen sind vom Fachmann so gewählt, dass bei der Verwendung der Vorrichtung einen Venturieffekt ausgelöst wird.The cavity 5 is cylindrical and its dimensions are chosen by the skilled person so that when using the device a Venturi effect is triggered.

Im oberen Teil des Venturikörpers 4 befindet sich die Zufuhrleitung 6, deren innerer Durchmesser dem Durchmesser des Hohlraums 5 entspricht. Die Zufuhrleitung 6 ist an den Venturikörper 4 geschweisst oder auf irgendwelche geeignete Weise befestigt.In the upper part of the Venturikörpers 4 is the supply line 6, whose inner diameter corresponds to the diameter of the cavity 5.

Fig. 3 stellt eine weitere Ausführungsform der Erfindung dar. Der Unterschied zwischen dieser Ausführungsform und der Ausführungsform der Fig. 1 und 2 liegt bei der Austrittsleitung 7, die in dieser Ausführungsform durch einen Verbindungsteil 11 und eine Austrittsdüse 10 verbunden ist. Fig. 3 represents a further embodiment of the invention. The difference between this embodiment and the embodiment of the Fig. 1 and 2 is located at the outlet conduit 7, which is connected in this embodiment by a connecting part 11 and an outlet nozzle 10.

Die Austrittsdüse 10 weist einen länglichen Teil 25 und einen dritten scheibenförmigen Teil 26 auf. Der Teil 25 ist zylinderförmig. Die Austrittsdüse 10 weist einen Durchgang 27 auf.The outlet nozzle 10 has an elongate part 25 and a third disc-shaped part 26. The part 25 is cylindrical. The outlet nozzle 10 has a passage 27.

Der Verbindungsteil 11 weist einen länglichen Teil 28 und einen vierten scheibenförmigen scheibenförmigen Teil 29 auf, der im Kontakt mit dem dritten scheibenförmigen Teil 26 ist. Die beiden scheibenförmigen Teile 26 und 29 haben im Wesentlichen den gleichen Durchmesser. Der Teil 28 ist mit der Austrittsleitung 7 trennbar verbunden.The connecting part 11 has an elongated part 28 and a fourth disk-shaped disk-shaped part 29, which is in contact with the third disk-shaped part 26. The two disc-shaped parts 26 and 29 have substantially the same diameter. The part 28 is separably connected to the outlet line 7.

Der scheibenförmigen Teil 26 stützt sich auf dem Venturikörper 4. Die scheibenförmigen Teile 26 und 29 weisen Bohrungen auf, durch welche Schrauben eingefügt werden können. Somit werden die Austrittsdüse 10 und der Verbindungsteil 11 gleichzeitig miteinander und am Venturikörper 4 trennbar verbunden.The disc-shaped part 26 is supported on the Venturi body 4. The disc-shaped parts 26 and 29 have holes through which screws can be inserted. Thus, the outlet nozzle 10 and the connecting part 11 are simultaneously connected to each other and to the Venturi body 4 separable.

Fig. 4 und 5 zeigen eine weitere Düse 30. Bei dieser Düse 30 besteht der Durchgang aus einem ersten Teil 31 und einem zweiten Teil 32. Der erste Teil 31 ist kegelstumpfartig und sein grösster Durchmesser befindet sich auf der Seite der Eintrittsleitung. Der zweite Teil 32 ist zylinderförmig. 4 and 5 show a further nozzle 30. In this nozzle 30, the passage consists of a first part 31 and a second part 32. The first part 31 is frustoconical and its largest diameter is located on the side of the inlet duct. The second part 32 is cylindrical.

Fig. 6 und 7 zeigen eine weitere Düse 33. Wie aus Fig. 7 ersichtlich, weist der Durchgang 34 einen gleichmässigen dreieckigen Querschnitt auf. Erfindungsgemäss muss diese Düse 33 einem Muffenteil, dessen Durchgang eine Querschnittsfläche aufweist, die in der Richtung des Hohlraums abnimmt, zugeordnet sein. 6 and 7 show another nozzle 33. Like out Fig. 7 As can be seen, the passage 34 has a uniform triangular cross-section. According to the invention, this nozzle 33 must be associated with a sleeve part whose passage has a cross-sectional area decreasing in the direction of the cavity.

Fig. 8 und 9 zeigen eine weitere Düse 35. Wie aus Fig. 9 ersichtlich, weist der Durchgang 36 einen gleichmässigen hexagonalen Querschnitt auf. Erfindungsgemäss muss diese Düse 35 auch einem Muffenteil, dessen Durchgang eine Querschnittsfläche aufweist, die in der Richtung des Hohlraums abnimmt, zugeordnet sein. 8 and 9 show another nozzle 35. Like out Fig. 9 As can be seen, the passage 36 has a uniform hexagonal cross-section. According to the invention, this nozzle 35 must also be associated with a sleeve part whose passage has a cross-sectional area decreasing in the direction of the cavity.

Fig. 10 und 11 zeigen eine weitere Düse 37. Wie aus Fig. 9 ersichtlich, weist der Durchgang 38 einen Querschnitt, der aus sieben gleichmässig angeordneten Scheiben besteht, auf. Erfindungsgemäss muss diese Düse 37 auch einem Muffenteil, dessen Durchgang eine Querschnittsfläche aufweist, die in der Richtung des Hohlraums abnimmt, zugeordnet sein. 10 and 11 show another nozzle 37. Like out Fig. 9 can be seen, the passage 38 has a cross section consisting of seven evenly arranged discs on. According to the invention, this nozzle 37 must also be associated with a sleeve part whose passage has a cross-sectional area decreasing in the direction of the cavity.

Eine weitere bevorzugte Ausführungsform der Erfindung ist in Fig. 12 und 13 dargestellt. Bei dieser Ausführungsform weist der Endteil 3a eine Düse und einen Muffenteil 40, die beide einen Durchgang 41 bzw. 42 aufweisen, dessen Querschnittsfläche in der Richtung des Hohlraums abnimmt.Another preferred embodiment of the invention is in Fig. 12 and 13 shown. In this embodiment, the end part 3a has a nozzle and a sleeve part 40, both of which have a passage 41 and 42, respectively, whose cross-sectional area decreases in the direction of the cavity.

Der Muffenteil 40 umfasst hier einen scheibenförmigen Teil 13, einen zylinderförmigen länglichen Teil 43, an welchem einen ersten zusätzlichen Teil 44 und einen zweiten zusätzlichen zylinderförmigen Teil 47 angeschlossen sind. Die Düse ist mit dem Venturikörper 4 trennbar verbunden. Der Teil 43 des Muffenteils 40 ist mit der Düse trennbar verbunden. Der Teil 47 ist mit der Eintrittsleitung 1 trennbar verbunden.The sleeve part 40 here comprises a disk-shaped part 13, a cylindrical elongate part 43, to which a first additional part 44 and a second additional cylindrical part 47 are connected. The nozzle is separably connected to the venturi 4. The part 43 of the sleeve part 40 is separably connected to the nozzle. The part 47 is separably connected to the inlet line 1.

Der erste zusätzliche Teil 44 ist ein exzentrischer Kegelstumpf, deren genaue Form am besten in Fig. 14 ersichtlich ist. Vorzugsweise besitzt der Teil 44 die Form, die man erhält, wenn man eine erste Scheibe 45 und eine zweite Scheibe 46, die einen grösseren Durchmesser als die Scheibe 45 hat, auf eine flache Ebene vertikal und parallel zu einander stellt, und ihre jeweilige Ränder miteinander verbindet. Diese Form hat den Vorteil, das praktisch keine Flüssigkeit im Muffenteil 40 bleibt, wenn die Vorrichtung nicht funktioniert.The first additional part 44 is an eccentric truncated cone whose exact shape is best in Fig. 14 is apparent. Preferably, the part 44 has the shape obtained by making a first disk 45 and a second disk 46 having a larger diameter than the disk 45 vertical and parallel to each other on a flat plane, and their respective edges with each other combines. This shape has the advantage that virtually no liquid remains in the sleeve part 40 when the device is not working.

Die Austrittsleitung ist durch einen Verbindungsteil 11a und eine Austrittsdüse 10a mit dem Hohlraum 5 verbunden. Der Verbindungsteil 11a weist einen länglichen Teil 28a und einen scheibenförmigen Teil 29a. Die Austrittsdüse 10a ist mit dem Venturikörper 4 trennbar verbunden. Der Teil 29a ist mit der Austrittsdüse 10a trennbar verbunden. Der Teil 28a ist mit der Austrittsleitung 7 trennbar verbunden.The discharge line is connected to the cavity 5 by a connecting part 11a and an outlet nozzle 10a. The connecting part 11a has an elongated part 28a and a disk-shaped part 29a. The outlet nozzle 10a is separably connected to the venturi 4. The part 29a is separably connected to the outlet nozzle 10a. The part 28 a is separably connected to the outlet line 7.

Die Querschnittsfläche des Durchgangs 57 des länglichen Teils 28a nimmt in der Richtung der Austrittsleitung 7 zu. Der längliche Teil 28a ist vorzugsweise im Wesentlichen kegelstumpfartig. Auf diese Weise wird ein eventuelles Zurückfliessen der Mischung, Suspension oder Dispersion in den Hohlraum vermieden.The cross-sectional area of the passage 57 of the elongated part 28a increases in the direction of the discharge pipe 7. The elongated portion 28a is preferably substantially frustoconical. In this way, a possible backflow of the mixture, suspension or dispersion is avoided in the cavity.

Ein Trichter 48 (s. Fig. 12) ist an die Zufuhrleitung 6a angeschlossen. Ein Ventil 49 ist zwischen dem Trichter 48 und der Zufuhrleitung 6a angeordnet. Der Trichter 48 ist kegelstumpfartig und mit einem Abstreifer 50 für die innere Wand 51 des Trichters 48 ausgerüstet. Der Abstreifer 50 ist durch Hebel 52 mit einem vertikalachsigen Zapfen 53 verbunden. Der Zapfen ist durch einen Gelenkantrieb 54 mit Hilfe eines elektrischen horizontal angeordneten Motors 55 gedreht. Auf diese Weise kann die innere Wand 51 des Trichters 48 regelmässig abgestriefen, was die Einführung eines pulverförmigen Feststoff in die Zufuhrleitung 6a auch erleichtert.A funnel 48 (s. Fig. 12 ) is connected to the supply line 6a. A valve 49 is disposed between the hopper 48 and the supply line 6a. The funnel 48 is frustoconical and equipped with a scraper 50 for the inner wall 51 of the funnel 48. The scraper 50 is connected by lever 52 with a vertical axis pin 53. The pin is rotated by a joint drive 54 by means of an electrical horizontally disposed motor 55. In this way, the inner wall 51 of the funnel 48 can be scraped off regularly, which also facilitates the introduction of a pulverulent solid into the supply line 6a.

Der Trichter 48 ist auch mit einer Spritzdüse 56 ausgerüstet. In dieser Weise kann er vorteilhaft zwischen zwei Anwendungen der Vorrichtung gespült werden.The funnel 48 is also equipped with a spray nozzle 56. In this way it can advantageously be purged between two applications of the device.
