Description

Aufgabevorrichtung für Saugtrockner.Feeding device for suction dryers.

Bei den bisher bei Saugtrocknern verwen deten oberen Aufgabetrögen macht sich der Übelstand besonders störend bemerkbar, daß eine dauernde Abdichtung zwischen dem Trog und dem sich drehenden Trommelmantel nicht möglich ist. Dadurch wird die zu entwässernde Masse nicht genügend' im Trog zurückgehalten und das bereits getrocknete Material wieder befeuchtet. Man hat nun schon, Aufgabevorrichtungen verwendet, welche den Trommelmantel nicht berühren, so daß das zu entwässernde Material frei aufgegeben wird. Diese bekannten Aufgabevorrichtungen haben vor allem den Nachteil, daß durch sie keine gleichmäßige Beschickung der Sangtrockner ermöglicht wird'. Das bezweckt aber die vorliegende Erfindung. With the upper feed troughs previously used with suction dryers the disadvantage is particularly noticeable that a permanent seal between the trough and the rotating drum shell is not possible. Through this the mass to be dewatered is not sufficiently retained in the trough and that already dried material re-moistened. You already have feeding devices used, which do not touch the drum shell, so that the material to be dewatered is freely abandoned. These known feeding devices have the main disadvantage that they do not allow even loading of the song dryer '. But that is the purpose of the present invention.

Durch dieselbe wird eine Aufgabevorrichtung geschaffen, durch welche in vollkommener Weise für eine durchaus gleichmäßige Verteilung der zu entwässernden Masse auf den Trommelumfang des Saugtrockners Sorge getragen wird. Um das zu erreichen, ist eine horizontal liegende hängende Rinne angeordnet, welche mehrere gemeinsame Ausläufe besitzt, die sich einzeln regulieren lassen. Um nun eine möglichst gleichmäßige Verteilung der zu entwässern den Masse auf dem Trommelumfang zu erhalten, ist die Aufgabevorrichtung in ihrer Längsrichtung hin und her beweglich angeordnet. Zum Zurückhalten von etwa am Trommelmantel herabfließender Schlämme dienen besondere Abstreichmesser, die am Trommelumfang vorgesehen sind.By the same a feed device is created through which in a perfect way for a thoroughly even distribution of the water to be drained Mass on the drum circumference of the suction dryer is taken care of. To achieve that, a horizontally lying hanging gutter is arranged, which several common Has outlets that can be individually regulated. In order to be as uniform as possible To obtain the distribution of the mass to be dewatered on the drum circumference, that is Feeding device arranged to be movable back and forth in its longitudinal direction. To the Retention of sludge flowing down on the drum shell serve special purposes Scraper knives, which are provided on the drum circumference.

Die Erfindung ist in einer beispielsweisen Ausführungsform in der Zeichnung dargestellt. Es zeigt: Fig. I eine Seiten-un, Fig. 2 eine Stirnansicht der Einrichtung. The invention is shown in an exemplary embodiment in FIG Drawing shown. It shows: FIG. 1 a side view, FIG. 2 an end view the facility.

Die Aufgaberinne, in welche die zu entwässernde Masse geleitet wird, ist über dem Trommelmantel frei hängend angeordnet Sie enthält beliebig viele Ausläufe b, durch die eine möglichst gleichmäßige Verteilung der zu entwässernden Schlämme. auf dem Trommelmantel vorgenommen wird. Um die Gleichmäßigkeit der Verteilung zu unterstützen, kann an der Rinne auch eine Einrichtung vorgesehen sein, welche eine Bewegung, z. B. eine hin und her schwingende Bewegung, derselben ermöglicht, wie das bei c angedeutet ist. Die Abstreichmesser für den auf der Trommel getrockneten Schlamm d sind derartig angeordnet, daß sie gleichzeitig etwa am Trommelmantel herab fließende Schlämme so lange zurückhalten, bis diese von der Saugwirkung der Trommel mitgenommen wird. The feed chute into which the mass to be dewatered is directed, is arranged freely hanging over the drum shell. It contains any number of outlets b, through which the sludge to be dewatered is distributed as evenly as possible. is made on the drum shell. To increase the uniformity of the distribution support, a device can also be provided on the channel, which a Movement, e.g. B. a reciprocating movement, the same allows how which is indicated at c. The scraper for the one dried on the drum Sludge d are arranged in such a way that they descend at the same time approximately on the drum shell Hold back flowing sludge until it is released from the suction effect of the drum is taken.
