Description

Unterdruckregler für Mühlen In Mühlen werden in umfangreichem Maße Belüftungssauganlagen benötigt, die die. einzelnen Maschinen durchlüften. Die Saugluft wird durch Exhaustoren erzeugt. Es wird nun aber auch Saugluft für Maschinen benötigt, die zum Sortieren von Mahlgut oder Getreide dienen. Hier kommt es darauf an, daß der Unterdruck stets gleichbleibend ist. Dies ist aber in den meisten Betrieben deshalb nicht der Fall, weil.,je nach Belastung der Anlage die Tourenzahl schwankt und dadurch ein stärkerer oder geringerer Unterdruck in den Sauglüftungen erzeugt wird. Da die Luft mit Filtern gereinigt wird, hängt auch die Höhe des Unterdrucks von dem Zustand der Filterschläuche ab.Vacuum regulator for mills In mills are used extensively Ventilation suction systems are required that the. Ventilate individual machines. The suction air is generated by exhaustors. But suction air is now also required for machines, which are used to sort grist or grain. What matters here is that the negative pressure is always constant. But this is the case in most companies therefore not the case, because the number of tours fluctuates depending on the load on the system and thereby a greater or lesser negative pressure is generated in the suction vents will. Since the air is cleaned with filters, the level of the negative pressure also depends on the condition of the filter bags.

Um nun einen -stets gleichmäßigen Unterdruck in den Rohrleitungen zu erzeugen, in denen es auf einen gleichmäßigen starken Saugstrom ankommt, beispielsweise bei der Grießsortierung, ist erfindungsgemäß ein in eine Rohrleitung einsetzbares Aggregat geschaffen; das bei wechselndem Unterdruck eine Drosselklappe betätigt, die in sich nochmals regelbar ist.In order to have a constant negative pressure in the pipelines to generate, in which it depends on a uniform strong suction flow, for example in the case of semolina sorting, according to the invention, one can be inserted into a pipeline Aggregate created; which actuates a throttle valve when the vacuum changes, which can be regulated again in itself.

Der Erfindungsgegenstand ist in der Zeichnung als Ausführungsbeispiel dargestellt.The subject of the invention is shown in the drawing as an exemplary embodiment shown.

i ist ein Saugrohr mit der um 2 drehbaren Drosselklappe 3. Durch eine Welle mit der Drosselklappe verbunden ist der Gewichtshebel ¢. Der Hebel, der außerhalb der Unterdruckleitung liegt, ist mit einem harmonikaähnlichen Teils verbunden. Der Innenraum des Teils 5 ist mittels des Rohres 6 mit der Saugseite des Unterdruckrohres verbunden. Die Luft nimmt den Weg der Pfeilrichtung. Steigt der Unterdruck auf der Saugseite, so zieht der dehnbare Hohlkörper 5 den Gewichtshebel q. nach oben und schließt die Klappe. Bei Nachlassen des Unterdruckes oder Ansteigen des Druckes. in dem anderen Leitungsteil öffnet sie sich wieder. Hierdurch wird ein Dru!ckausggleich in der Leitung geschaffen. Die Haupteinstellung erfolgt dadurch, daß der Gewichtshebel ¢ auf der Welle 2 verstellbar ist. Der Einstellung dient die Skala 7.i is an intake manifold with the throttle valve 3 which can be rotated by 2 Shaft connected to the throttle valve is the weight lever ¢. The lever that is outside the vacuum line is connected to a harmonica-like part. Of the The interior of the part 5 is connected to the suction side of the vacuum pipe by means of the pipe 6 tied together. The air takes the path in the direction of the arrow. If the negative pressure increases on the On the suction side, the expandable hollow body 5 pulls the weight lever q. up and closes the flap. When the vacuum drops or the pressure rises. in the other part of the line it opens again. This creates a pressure compensation created in the line. The main setting is made by the weight lever ¢ is adjustable on the shaft 2. Scale 7 is used for setting.
