Description
Röhrentrockner Bei Röhrentrocknern, insbesondere Dampfröhrentrocknem hat es sich gezeigt, daß die Füllung der einzelnen Rohre mit ihrem Abstand von der Drehachse des Trockners sich ändert. Man hat versucht, diesen Mangel durch Nachfüllvorrichtungen, Einblasevorrichtungen oder besonders gebauteFüllwalzen oder Füllrümpfe zu beheben. Es ist nicht immer möglich, vor allem bei Trocknern älterer Bauart, durch einfache Mittel die Füllung der äußeren und inneren Rohrkreise gleichmäßig zu halten. Verschiedene Rohrfüllungen rufen aber wieder verschiedene Trocknungsgrade hervor.Tube dryer For tube dryers, especially steam tube dryers it has been shown that the filling of the individual tubes with their distance from the The axis of rotation of the dryer changes. Attempts have been made to remedy this deficiency by means of refill devices, To fix blowing devices or specially built filling rollers or filling hulls. It is not always possible, especially with older types of dryers, by simple Means to keep the filling of the outer and inner pipe circles evenly. Different However, pipe fillings cause different degrees of dryness.
Bei der Trocknung von Brikettierkohle macht es sich besonders unangenehm bemerkbar, wenngroßeWassergehaltsspannen bei der Trockenkohle auftreten. Die Wassergehaltsspanne der Trockenkohle wird vergrößert, wenn die Trockenleistungen der Rohre verschieden sind.It is particularly uncomfortable when drying briquetting charcoal noticeable when large water content ranges occur in the dry coal. The water content range the dry coal is increased when the drying capacities of the pipes differ are.
Es ist bekannt, daß mittels Wendeleisten die spezifische Verdampfungsleistung eines Trockners und damit der Grad derTrocknung des Trockengutes beeinflußt werden kann.It is known that the specific evaporation capacity is achieved by means of spiral strips a dryer and thus the degree of drying of the items to be dried can.
Nach derErfindung werden in einenTrockner die in die Rohre eingebauten Wendeleisten verschieden gestaltet, um die Trockenleistung in den einzelnen Rohrkreisen einander anzupassen.According to the invention, those built into the pipes are placed in a dryer Reversible bars designed differently to improve the drying performance in the individual pipe circles to adapt to each other.
Bei derVerwendungvon schraubenförmigen Wendeleisten kann man die Trockenleistung entweder durch Änderung der Länge der Wendeleiste oder durch Änderung der Ganghöhe der einzelnen Schraubenwindungen verändern. Nach der Erfindung werden die inneren Rohrkreise, die eine größere Füllung aufweisen, mit stärker wirkenden Wendeleisten als die äußeren versehen. Wendeleisten, deren Außendurchmesser geringer ist als der der Trockenrohre, können ohne Schwierigkeit in ihrer Ganghöhe geändert werden, so daß hierdurch auf einfache Weise die Trockenleistung jedes einzelnen Rohres an eine Normalleistung angeglichen werden kann. Man kann auch die Längen der einzelnen Wendeleisten durch Abschneiden oder Anschweißen verändern und so eine gleichmäßige Trockenwirkung aller Rohre hervorrufen.When using helical spiral strips, you can reduce the drying performance either by changing the length of the turning bar or by changing the pitch of the individual screw turns. According to the invention, the inner Circles of pipes that have a larger filling, with more effective spiral strips than the outer ones provided. Spiral strips, the outside diameter of which is smaller than that of the drying tubes can be changed in their pitch without difficulty, so that in this way the drying performance of each individual tube is easily achieved a normal service can be adjusted. One can also change the lengths of each Change the turnable strips by cutting or welding them to create a uniform one Make all pipes dry.
Auf der Zeichnung sind vier verschiedene Ausführungsbeispiele eines Röhrentrockners nach der Erfindung gezeigt.In the drawing there are four different exemplary embodiments Tubular dryer according to the invention shown.
Nach Abb. i soll die beabsichtigte Wirkung durch verschiedene Länge der Wendeleisten erzielt werden. Demnach sind in den äußeren Rohren des Trockners kurze Wendeleisten i und in den inneren Rohren lange Wendeleisten 3 eingebaut. Die Wendeleisten :2 in den Rohren der dazwischenliegenden Rohrkreise sind zwischen den Längen der Wendeleisten i und 3 abgestuft. ' Bei der Anordnung nach Abb. 2 haben die Wendeleisten die gleiche Länge, haben aber verschiedene Steigung, und zwar haben die yVendeleisten4der innerenRohre die geringste Steigung und die Wendeleisten 6 der äußeren. Rohre die größte Steigung, während die Wendeleisten 5 der dazwischenliegenden Rohre wieder eine mittlere Steigung aufweisen.According to Fig. I, the intended effect is supposed to be through different lengths the turning strips can be achieved. Accordingly, are in the outer tubes of the dryer short spiral strips i and long spiral strips 3 built into the inner tubes. the Spiral strips: 2 in the tubes of the tube circles in between are between the Lengths of the spiral strips i and 3 graded. 'With the arrangement according to Fig. 2 have the spiral strips have the same length, but have different inclines, and indeed have the yvendel strips 4 of the inner pipes have the smallest incline and the spiral strips 6 the outer. Pipes have the greatest slope, while the spiral strips 5 of the intermediate Tube again have a medium slope.
In diesen Beispielen sind schraubenförmige Wendeleisten mit geringerem Durchmesser als der der Trockenrohre angenommen. Solche Wendeleisten können ohne Schwierigkeit sowohl in bezug auf ihre Länge als auch in bezug auf ihre Ganghöhe an Ort und Stelle geändert werden.In these examples, helical helical strips are less Diameter assumed to be that of the drying tubes. Such spiral strips can be used without Difficulty both in terms of their length and in terms of their pitch can be changed on the spot.
In Abb. 3 ist ein Trockner gezeigt, bei dem verschiedene -Arien von Wendeleisten verwandt sind. Die Wendeleisten 7 der äußeren Rohre bestehen hier aus zwei Längsleisten, während die Wendeleisten 8 der mittleren Rohre aus vier Längsleisten von unter sich verschiedener Länge gebildet sind. Die inneren Rohre sind wieder mit Schraubenwendeleisten 9 versehen.In Fig. 3 a dryer is shown in which various aria of spiral strips are related. The turning strips 7 of the outer tubes consist of two longitudinal strips, while the turning strips 8 of the central tubes are formed from four longitudinal strips of different lengths. The inner tubes are again provided with helical helical strips 9.
Bei dem Trockner nach Abb. q. sindWendeleisten. mit Nachwalzknüppeln angeordnet. Hier wird die Beeinflussung desTrockenguies durch verschiedene Länge und Lage der Nachwalzknüppel erreicht. Die inneren Rohre sind demnach mit Schraubenleisten io und verhältnismäßig langen Nachwalzknüppeln 13 versehen, die von dem Austrittsende des-Trockenrohres entfernt angeordnet sind. Die mittleren Rohre zeigen Schraubenleisten 12, mit kurzen Nachwalzknüppeln iq., die ebenfalls entfernt vom Austrittsende eingebaut sind. Die äußeren Rohre zeigen Schraubenwendeleisten 12 mit langenNachwalzknüppeln 15, die aber bis an das Austrittsende reichen. Es bleibt vorbehalten, dieseErfindung nicht nur auf Dämpfröhrentrockner, sondern auch auf Feuergastrockner, die mit Wendeleisten arbeiten, anzuwenden.With the dryer according to Fig. Q. are reversible bars. with re-rolling billets arranged. Here, the influence of the drying run is due to different lengths and position of the re-rolling billets reached. The inner tubes are therefore with screw strips io and relatively long re-rolling billets 13 provided from the exit end des drying tube are arranged remotely. The middle tubes show screw strips 12, with short re-rolling billets iq., Which are also installed at a distance from the exit end are. The outer tubes show helical helical strips 12 with long re-rolling billets 15, which, however, extend to the exit end. It is reserved to thisinvention not only on steam tube dryers, but also on flue gas dryers with spiral strips work, apply.
