Description

Rollentrockner für Furniere Wenn bei Rollentrocknern, wie sie zur Trocknung von Furnieren -zur Anwendung _gelanben, die heiße Luft mittels eines Ventilators im Kreislauf durch die Trockenkammer und eine außerhalb der Trockenkammer angeordnete Rückleitung "geführt wird, so entstehteinerseits eine Druckzone, in welcher der Luftdruck höher ist als der Druck der Außenluft, und andererseits eine Saugzone. vor dem Ventilator, in welcher der Luftdruck etwas geringer ist als hei der Außenluft.--Den Unterdruck vor dem Ventilator kann man dazu benutzen, durch Frischluftstutzen mit regelbarer Öffnung eine ,giewiee 'enge Frischluft anzusaugen, um allmählich die sich mit Feuchtigkeit anreichernde, im Trockner kreisende Luft durch Frischluft zu ersetzen. Durch das Ansaugen von Frischluft wird die Druckzone in der Trockenkammer vergrößert und die Saugzone verkleinert, da mehr Luft eingeblasen als abgesaugt wird. Die überschüssige Luft wird durch de an dem Austrittsende des Troclcners vorhandenen Spalten, die zur Herausführung des Trockengutes dienen, infolge des Überdruckes entweichen. Die entweichende feuchte und warme Luft kann zu einer Belästigung der Arbeiter, welche das Aufnehmen des Trockengutes b.ewirken, führen.Roller dryer for veneers If with roller dryers, how they are used Drying of veneers - for application _yellow, the hot air by means of a fan in the circuit through the drying chamber and one arranged outside the drying chamber Return line ", then on the one hand a pressure zone is created in which the Air pressure is higher than the pressure of the outside air, and on the other hand a suction zone. in front of the fan, in which the air pressure is slightly lower than that of the outside air - Den Negative pressure in front of the fan can be used through the fresh air connection adjustable opening to suck in a 'how-like' narrow fresh air to gradually increase the Air that is enriched with moisture and circulates in the dryer through fresh air to replace. The pressure zone in the drying chamber is created by sucking in fresh air enlarged and the suction zone reduced, since more air is blown in than sucked out will. The excess air is removed by de existing at the exit end of the dryer Columns, which serve to lead out the dry material, due to the overpressure escape. The escaping moist and warm air can be a nuisance to the Workers who are responsible for picking up the dry goods.

Die Erfindung besteht darin, daß an dem Austrittsende des Trockengutes eine Vorkammer angeordnet ist, die mit einer Abzugesse versehen ist. Die aus der Trockenkammer austretende feuchte. Luft wird 'von der Vorkammer aufgenommen und durch die Esseabgeführt; gegebenenfalls kann man auch einen künstlichen Zug durch einen kleinen Ventilator oder ein Flügelrad @erzeugen.The invention consists in that at the exit end of the dry material an antechamber is arranged, which is provided with a hood. The ones from the Damp escaping from the drying chamber. Air is taken in by the antechamber and discharged through the meal; if necessary, you can also use an artificial train @generate a small fan or impeller.

Die Abbildung zeigt ein Ausführungsbe.-spiel der Anlage gemäß der Erfindung. a ist die Trockenkammer, b der Ahsaugestutzen, c der Frisch Luftstutzen, d der Ventilator, e die Luftleitung, in welche auch noch Erhitzer zum Wiederanwärmen der Luft eingehaut sein können, f sind die Einblasekammern. An dem rechten Ende der Trockenkammera, an dem die Furniere austreten, ist die Vorkammier g .vorgelagert, welche durch eine Trennwand h gegen die Trockenkammer abgeschi;eden ist. Am toteren Ende der Trockenkammerg befindet sich die Abzugessel. Die aus der Trockenkammer durch die unvermeidlichen Spalten der Trennwand h austretende feuchte und warme Luft wird von der Vorkammer g aufgenommen und durch die Abzugesse i ins Freie geleitet.The figure shows an exemplary embodiment of the system according to Invention. a is the drying chamber, b the suction nozzle, c the fresh air nozzle, d the fan, e the air duct, in which there is also a heater for reheating can be entrained in the air, f are the injection chambers. At the right end The drying chamber, where the veneers emerge, is preceded by the pre-chamber, which is separated from the drying chamber by a partition h. Most dead The exhaust boiler is located at the end of the drying chamber. The ones from the drying chamber through the inevitable gaps in the partition h, moist and warm escaping Air is taken in by the antechamber g and passed into the open through the exhaust hood i.
