Verfahren zum Regeln der Leistung von Mahlanlagen mit Austragung und VerteilungProcedure for regulating the performance of grinding plants with discharge and distribution
des Mahlgutes durch einen Luftstrom.of the ground material through an air stream.
Bei allen Mühlensystemen ist die Speisevorrichtung der Mühle ein. wichtiger Bestandteil der Mahlanlage. Um sie jeder gewünschten ,Leistung anpassen zu können, ist die Mahlgutaufgabe in möglichst weitem Bereich einstellbar. Da die Mühlen nur die Mengen Mahlgut liefern, auf die die Speisevorrichtung eingestellt ist, so ist man bei schwankender Entnahme des fertigen Mahlgutes gezwungen, ίο in Silos zu mahlen, aus denen man das Mahlgut im gegebenen Zeitpunkte dem Bedarf entsprechend entnimmt.In all mill systems, the feed device of the mill is a. important ingredient the grinding plant. The regrind task is to be able to adapt it to any desired output adjustable in as wide a range as possible. Because the mills only deliver the amount of grist that the feeder can handle is set, one is forced with fluctuating removal of the finished grist, ίο to grind in silos, from which you can get the grist at the given times according to the needs removes.
Vorliegende Erfindung bezweckt, bei pneumatischen Mahlanlagen die Leistung der Mühle ohne Ausgleichsilo oder ähnliche Vorrichtungen der jeweiligen Entnahme an fertigem Mahlgut selbsttätig anzupassen. Dies ist bei Mühlen mit Austragung durch einen Luftstrom möglich, dessen Druck auch bei noch so weiter Entfernung der EntnahmestellenThe present invention aims, in pneumatic grinding systems, the performance of the Mill without compensation silo or similar devices for the respective removal of the finished product Adjust regrind automatically. This is the case with mills that are discharged by an air stream possible, its printing even if the removal points are so far away
sich bei wechselnder Luft- oder Staubentnahme verändert. Diese Druckveränderung soll nun dazu, dienen, dje Steuerung eines Druckwasserkolbens zu betätigen, der es durch Einstellen der Aufgabevorrichtung, beispielsweise durch Verstellen des Abstreichers einer! TeUeiaufgabevorrichtung·, ermöglicht, die Leistung dem Bedarf an Mahlgut anzupassen. Statt der pneumatisch beeinflußten Druckwassersteuerung kann der Abstreicher auch durch, irgendeine beliebige andere Vorrichtung bewegt werden.changes with changing air or dust extraction. This change in pressure should now serve to control one Pressurized water piston to actuate it by adjusting the feed device, for example by adjusting the scraper one! Expensive feeder · enables that Adjust performance to the need for regrind. Instead of the pneumatically influenced pressure water control the scraper can also be carried out by any other device be moved.
In der Zeichnung ist eine beispielsweise Einrichtung zur Ausführung des Verfahrens scftematisch dargestellt, und zwar bedeutet α die Aufgabesstelle für das Mahlgut, b eine Telleraufgabevorrichtung·, € die Mühle, d die Saugleitung, die zum Exhaustor e führt, der das fertige Mahlgut der Leitung d entnimmt.In the drawing, an example of a device for carrying out the process is shown schematically, namely α means the feed point for the ground material, b a plate feeding device, € the mill, d the suction line that leads to the exhaustor e , which carries the finished ground material from line d removes.
/ ist ein Druckmesser, der durch das Röhrchen g der Saugleitung d verbunden ist und durch die jeweiligen Druckschwankungen in der Leitung betätigt wird. Der Druckmesser/ steuert seinerseits das Ventil k, das je nach seiner Stellung das aus irgendeiner Quelle zur Verfügung stehende Druckmittel durc'h eine der beiden Leitungen h oder i vor oder hinter den Druckkolben / führt. Durch die Kolbenstange η wird der Abstreicher tn bewegt, der es je nach seiner Stellung ermöglicht, die Menge des Aufgabegutes dem Verbrauch entsprechend anzupassen./ is a pressure gauge which is connected to the suction line d through the tube g and is actuated by the respective pressure fluctuations in the line. The pressure gauge / controls the valve k, which, depending on its position, guides the pressure medium available from any source through one of the two lines h or i in front of or behind the pressure piston /. The scraper tn is moved by the piston rod η , which, depending on its position, makes it possible to adapt the amount of the feed material to the consumption accordingly.
An Stelle des Telleraufgabeapparates kann auch eine andere geeignete Aufgabevorrichtung Verwendung finden.Instead of the plate feeder, another suitable feeder can also be used Find use.
Das Verfahren bietet außer dem Wegfall der Wartung an den Mühlen den weiteren, nicht zu unterschätzenden Vorteil, daß irgendeine Aufspeicherung des gemahlenen Gutes sich in fast allen Eällen vollkommen erübrigt, wodurch auch die Gestehungskosten der Anlage erheblich geringer werden.In addition to the elimination of maintenance on the mills, the process also offers The advantage that should not be underestimated is that there is any accumulation of the ground material is completely unnecessary in almost all cases, which also reduces the cost of the system will be considerably lower.
