Steuerung für dreikammerige Wasser- oder Schlammheber.Control for three-chamber water or sludge lifters.

Patentiert im Deutschen Reiche vom 6. April 1911 ab.Patented in the German Empire on April 6, 1911.

Es ist bekannt, Wasser oder Schlamm mittels eines gasförmigen Druckmittels dadurch zu heben, daß man das Fördergut in einen Behälter eintreten läßt und denselben nach seinem Auffüllen gegen die Zuführungsleitung abschließt, gegen die Förderleitung dagegen öffnet und ihn unter Druck setzt, so daß sein Inhalt zwangläufig in die Förderleitung übergeführt wird. Desgleichen ist es bekannt,It is known that water or mud by means of a gaseous pressure medium thereby to raise that one lets the conveyed material enter a container and the same after its filling completes against the supply line, against the delivery line opens and puts it under pressure so that its contents are inevitably transferred into the delivery line will. It is also known

ίο drei solcher Behälter mit einer Luftpumpe und einem Kompressor durch einen Sechsweghahn derart in Verbindung zu bringen, daß, während der eine Behälter- gefüllt wird und ein zweiter Behälter bereits gefüllt ist, die in dem dritten Behälter von der vorhergehenden Druckperiode befindliche Druckluft in den Kompressor und aus diesem in den gefüllten Behälter übergeführt wird, um auf diese Weise einen ökonomischen Betrieb zu schaffen. Es wird also die Hahnsteuerung schrittweise eine solche Stellung einnehmen, daß dieser Arbeitsvorgang der Reihenfolge nach sich abzuwickeln vermag.ίο three such containers with an air pump and to be brought into communication with a compressor by a six-way cock such that, during the one container is filled and a second container is already filled, the one in the third container from the previous one Pressure period located compressed air in the compressor and from this in the filled container is transferred to in this way to create an economical operation. So it becomes the tap control gradually assume such a position that this operation of the sequence able to unwind.

Die Fig. 1 der Zeichnung zeigt das Schema einer derartigen Anordnung.Fig. 1 of the drawing shows the scheme of such an arrangement.

Es sind hierbei a, b, c die drei Förderkammern, während K den Kompressor, L die "Luftpumpe und S den Sechswegschieber bzw. Sechsweghahn darstellt.Here a, b, c are the three delivery chambers, while K represents the compressor, L the "air pump and S the six-way slide valve or six-way valve.

Der Behälter α ist gefüllt· und soll entleert werden. Der Behälter b befindet sich in der Füllperiode, während der Behälter c entleert ist. Es saugt bei der gezeichneten Hahnstellung der Kompressor K die im Behälter c befindliche Druckluft durch die Leitungen e und d an und drückt sie durch die Leitung f und g in den Behälter a. Die Luftpumpe L saugt dagegen unter Vermittlung der Leitungen i und h den Behälter b leer, so daß das Fördergut denselben zu füllen vermag. Die angesaugte Luft wird von der Luftpumpe L durch die Leitung k ins Freie ge- ' stoßen. Ist Behälter b gefüllt und Behälter a entleert, dann wird die Hahnsteuerung so verstellt, daß im Behälter c durch die Luftpumpe Unterdruck hergestellt wird und die im Behälter α befindliche Druckluft durch den Kompressor angesaugt und in den Behälter b befördert wird.The container α is filled and should be emptied. The container b is in the filling period, while the container c is emptied. In the cock position shown, the compressor K sucks in the compressed air in the container c through the lines e and d and pushes it through the lines f and g into the container a. The air pump L , on the other hand, sucks the container b empty through the intermediary of the lines i and h , so that the conveyed material is able to fill the same. The sucked in air is pushed into the open air by the air pump L through the line k. When container b is full and container a is emptied, the valve control is adjusted so that a vacuum is created in container c by the air pump and the compressed air in container α is sucked in by the compressor and conveyed into container b.

Die Verstellung des Hahnes wurde bisher von Hand aus vorgenommen.The cock was previously adjusted by hand.

Die Erfindung dient dazu, diese Verstellung selbsttätig herbeizuführen. Dies kann auf rein mechanischem Wege unter Vermittlung eines Druckmittels oder auf elektrischem Wege erfolgen. Zu diesem Zweck wird gemäß Fig. 2 der Zeichnung jeder Behälter mit zwei Schwimmern 5, 6 versehen, von denen der obere beim höchsten, der untere beim tiefsten Flüssigkeitsstande seine Wirkung ausübt. Die Schwimmerstange 7 ist mit einem Schieber 8 versehen, der seinerseits in bekannter Weise durch auf einem um Bolzen 9 schwingenden Winkelhebel 10 angeordnete Beruhigungsgewichte 11 und 12 bis zum Augenblick seiner Umsteuerung in der erforderlichen Stellung gehalten wird. Durch diesen Schieber wird je eine der drei Leitungen 13, 14 und 15 abwechselnd mit der ebenfalls von dem Kompressor gespeisten Druckleitung 16 und mit einer ins Freie mündenden Leitung 17 in Verbindung gebracht.The invention serves to bring about this adjustment automatically. This can be done in a purely mechanical way with the mediation of a pressure medium or by electrical means. For this purpose, according to FIG. 2 of the drawing, each container is provided with two floats 5, 6, of which the upper one exerts its effect on the highest and the lower one on the lowest liquid level. The float rod 7 is provided with a slide 8, which in turn is held in the required position in a known manner by settling weights 11 and 12 arranged on an angle lever 10 swinging around bolt 9 until it is reversed. Through this slide, one of the three lines 13, 14 and 15 is alternately connected to the pressure line 16, which is also fed by the compressor, and to a line 17 opening into the open air.

Mit dem Sechsweghahn 5 ist eine Kurbel 19 verbunden, mittels deren das Küken des Sechsweghahnes gedreht wird. Die Kurbei 19 ist mit drei Kolben verbunden, die in drei Zylindern 20, 21, 22 arbeiten. Soll in Fig. ι der Behälter b gefüllt werden und istA crank 19 is connected to the six-way cock 5, by means of which the plug of the six-way cock is rotated. The crank 19 is connected to three pistons that work in three cylinders 20, 21, 22. If in Fig. Ι the container b is filled and is

Claims

the container c emptied, the container α is filled, however, then the slide 8 of the two containers b and c will assume its lowest position and thereby the lines 14 and 13 with the exhaust lines 17 and due to the highest float position in the container a, the slide is the Bring line 15 with the pressure line 16 in connection, so that the pressure medium coming from the compressor, which can optionally also be generated by another pressure source, can enter the cylinder 22, while the pressure medium can escape from the cylinders 20, 21 . As a result, the crank ig is brought into the position shown in FIG. Ι and consequently the six-way slide valve or six-way valve is brought into the position shown, so that the compressor and air pump are now able to exert their effect in such a way that container b is sucked empty and the pressure medium is removed Container c is sucked into the compressor and conveyed from this into the container α. But since the six-way slide valve or six-way valve reverses each time it is turned by 60 ° and all three containers go through their period within a rotation of 180 °, while the crank completes a rotation of 360 ° within the same time, the drive of the crank must on the six-way cock with the mediation of a transmission gear 23, 24, as it is shown schematically in Fig. 3 in the upper view, are made. If you want to make the drive electrically, then you can use the device shown schematically by Fig. 4 and 4a / · and also using the float and slide device and the crank driven by three pistons, only that the latter in this case has no connection with the six-way cock. The crank, on the other hand, is connected to a sliding contact 25 which slides over three insulated contact segments 26, 27, 28. Both the sliding contact and the contact segments are connected to the circuit 29 of the power source 30 and the motor 31. The motor 31 itself drives a screw wheel 33 seated on the plug of the six-way valve 5 through the screw 32. Six contact pieces 34 are arranged on the rotatable plug and move under the sliding contact 35. The dash-dotted line 36 branches off from the cock plug, and the dash-dotted line 37 branches off from the sliding contact 35 to the motor 31, in which line a power source 38 is also switched on In this embodiment, if the sliding contact 25 slides over one of the contact segments 26, 27, 28, depending on whether the crank mechanism has been moved by the piston of one of the pressure cylinders 20, 21, 22, then the circuit 29 is closed and the motor 31 in Movement is set so that an adjustment of the cock takes place. But since there is no sufficient security that the switch of the cock is carried out within this sliding contact of the sliding contact 25 over the relevant segment contact, the second circuit 37 with the contacts 34, 35 is After the cock plug is set in motion, the sliding contact 35 comes with it one of the contact pieces 34 in connection, closes the circuit 37, so that the motor 31 is still fed even when the sliding contact 25 is already in the off position and the cock can turn until the sliding contact 35 comes to the off position . If the slide 8 is then brought into its upper position in one of the containers and the associated pressure cylinder 20 to 22 is provided with pressure, then the same process takes place.
