Description
Drehtrommel zum gleichzeitigen Trocknen und Mahlen Es sind umlaufende Trommeln bekannt, in denen gleichzeitig ein Trocknen und Mahlen des zu behandelnden Gutes in getrennten Kammern vorgenommen wird, und zwar sind hierbei die einzelnen Kammern, zwischen denen auch noch Zwischenkammern vorhanden sein können, entweder neben- oder ineinander angeordnet. Hierbei war es aber bisher nicht möglich, jede dieser Kammern in der gerade für sie erforderlichen Weise zu belüften und so die beste Wirkung zu erzielen.Rotary drum for simultaneous drying and grinding. They are rotating Drums known, in which a drying and grinding of the to be treated at the same time Good things are done in separate chambers, namely the individual ones Chambers, between which there may also be intermediate chambers, either arranged next to or inside one another. So far it has not been possible for everyone to ventilate these chambers in the manner precisely required for them and so the to achieve the best effect.
Die Erfindung erreicht dies dadurch, daß die einzelnen Kammern von getrennten Luftströmen durchzogen werden, wie es bereits bei Vorrichtungen bekannt ist, bei denen wenigstens ein Teil einer der Kammern, _ etwa deren Mantel, feststeht.The invention achieves this in that the individual chambers of separate air currents are traversed, as is already known in devices in which at least part of one of the chambers, such as its jacket, is fixed.
Um die Durchströmung der einzelnen Kammern gemäß der Erfindung in einfacher Weise zu erreichen, erfolgt die Zu- und Ableitung der Luft durch gleichachsig ineinander angeordnete hohle Zapfen an sich bekannter Art.To the flow through the individual chambers according to the invention in To achieve a simple way, the supply and discharge of the air is done on the same axis hollow pins of a type known per se arranged one inside the other.
Die Zeichnung stellt mehrere Ausführungsbeispiele der Erfindung dar und zeigt in Abb. i den Längsschnitt durch eine Trommel, Abb. 2 einen Querschnitt nach Linie II-11 der Abb. i, Abb.3 im Längsschnitt ein weiteres Ausführungsbeispiel.The drawing shows several exemplary embodiments of the invention and shows in Fig. i the longitudinal section through a drum, Fig. 2 shows a cross section according to line II-11 of Fig. i, Fig.3 in longitudinal section another embodiment.
Durch eine Zuleitung i (Abb. i) wird das zu behandelnde Gut in die Trockenkammer 2 der Trommel eingetragen. Das fertiggetrocknete Gut tritt durch öffnungen ¢ der Querwand 5 in die Zwischenkammer, die von der Siebwand 5 und der vollen Wand 6 gebildet wird. In dieser Zwischenkammer vorgesehene Hubschaufeln 7 leiten das Gut durch die Mittelöffnung 8 der Wand 6 in die mit Mahlkörpern 9 ausgerüstete Mahlkammer i o, wo es in bekannter Weise gemahlen wird.Through a supply line i (Fig. I), the material to be treated is fed into the Entered drying chamber 2 of the drum. The finished dried product passes through openings ¢ the transverse wall 5 into the intermediate chamber, that of the sieve wall 5 and the full wall 6 is formed. Lifting blades 7 provided in this intermediate chamber guide this Well through the central opening 8 of the wall 6 into the grinding chamber equipped with grinding media 9 i o, where it is ground in a known manner.
Gleichachsig mit der Trommel ist von der Trocknerseite her ein Rohr i i eingeführt, welches durch die Querwände 5 und 6 hin- _ durchreicht und erst in der Mahlkammer endet. Um dieses Rohr ist ein zweites Rohr 12 herumgelegt,- und um dieses ist ein weiteres Rohr 13 angeordnet, welches den Führungszapfen des Trommelsystems 2, 1o bildet und zur Einführung von Heißluft dient. Die Heißluft wird in der Trommel durch schraubenförmige Flügel 14 verteilt, um mit dem ganzen durch die Zuleitung i eingetragenen Gut in Berührung gebracht zu werden und nach dessen Trocknung als Brüden durch das Rohr 12 abzuziehen.A pipe is coaxial with the drum from the dryer side i i introduced, which passes through the transverse walls 5 and 6 and only ends in the grinding chamber. A second tube 12 is wrapped around this tube, - and around this a further tube 13 is arranged, which the guide pin of the drum system 2, 1o forms and serves to introduce hot air. The hot air is in the drum distributed by helical wings 14 to get with the whole through the supply line i registered good to be brought into contact and after its drying as Withdraw vapors through pipe 12.
In die Mahlkammer i o sind Kugeln 9 und ähnliche Mahlkörper in bekannter Weise eingefüllt. Das genügend gefeinte Mahlgut wird durch die Luft, welche durch die Leitung i i eintritt und durch eine vor deren Mündung angeordnete Prallfläche 17 zerteilt wird, durch die Ableitung 18 ausgetragen.Balls 9 and similar grinding bodies are known in the grinding chamber i o Way filled. The sufficiently fine grist is made by the air, which is through the line i i enters and through a baffle arranged in front of its mouth 17 is divided, discharged through the derivative 18.
Jede Kammer wird demnach von einem besonderen Luftstrom durchzogen.Each chamber is therefore traversed by a special air flow.
Bei dem in Abb.3 dargestellten Ausführungsbeispiel sind die beiden Kammern 20 und 21 nicht an-, -sondern ineinandergefügt, wobei die Mahlkammer 21 innen liegt, damit die Mahlkörper 22 frei durch den Kammerraum fallen können.In the embodiment shown in Figure 3, the two are Chambers 20 and 21 not attached to one another, but rather inserted into one another, the Grinding chamber 21 lies inside, so that the grinding bodies 22 freely fall through the chamber space can.
Das fertiggetrocknete Gut verläßt die Trockenkammer 2'o durch im Trommelmantel vorgesehene öffnungen 23, die während des größten Teiles des Umlaufs durch die Kappe 24 verschlössen sind, in deren tiefstem Punkt die Ableitung 25 angeordnet ist, welche das ausfallende Gut mittels hier nicht dargestellter Fördermittel in die Mahltrommel 21 verbringt. Auch hier ist jede Trommel von einem besonderen Luftstrom durchzogen, zu dessen Erzeugung erforderlichenfalls hier nicht dargestellte Gebläse Verwendung finden.The finished dried material leaves the drying chamber 2'o through the drum shell provided openings 23, which during most of the circulation through the cap 24 are closed, at the lowest point of which the discharge line 25 is arranged, which the falling material into the grinding drum by means of conveying means not shown here 21 spends. Here, too, each drum is traversed by a special air stream, to generate it, if necessary, use a fan not shown here Find.
Der Weg der Trockenluft ist in der Zeichnung durch weiße Pfeile, derjenige der Frischluft durch schwarze Pfeile gekennzeichnet.The path of the dry air is indicated by white arrows in the drawing the fresh air indicated by black arrows.
An Stelle der einen Mahlkammer können verschiedene hintereinander liegen und dann in bekannter Weise mit stets kleiner werdenden Mahlkörpern für immer feinere Mahlung ausgestattet sein.Instead of one grinding chamber, different ones can be used one after the other and then in the known way with ever smaller grinding media forever finer grind.
Die Vorrichtung ist besonders geeignet für das Verarbeiten sehr feuchten Mahlgutes. Der Vorteil ist in der Benutzung von zwei getrennten Luftkreisen zu sehen, da hierdurch der Mahlkammer kühle Frischluft zugeführt wird, während andererseits mit -der Trockenluft kein oder nur wenig Staub abgeführt wird, also ein geringer Verlust an Gut entsteht.The device is particularly suitable for processing very moist Grist. The advantage is to be seen in the use of two separate air circuits, since this supplies cool fresh air to the grinding chamber, while on the other hand With -the dry air no or only a little dust is removed, so a little Loss of goods occurs.
