Description
Trockenvorrichtung mit luftdurchlässigen, endlos umlaufenden Förderbändern Die Erfindung betrifft eine Trockenvorrichtung mit luftdurchlässigem, endlos umlaufendem Förderbande, bei welcher die Trokkengase von unten nach oben durch das Trockengut hindurchgeführt werden. Das, Kennzeichen des Erfindungsgegenstandes besteht darin, daß das Band zur Auflockerung der Trockengutschicht mit in Abständen angeordneten Abhebemessern versehen ist.Drying device with air-permeable, endlessly rotating conveyor belts The invention relates to a drying device with air-permeable, endlessly revolving Conveyor belt, in which the dry gases from bottom to top through the dry goods be passed through. The characteristic of the subject matter of the invention is that the tape for loosening the dry material layer with spaced apart Lifting knives is provided.
Ein weiteres Kennzeichen des Erfindungsgegenstandes besteht darin, daß zur Regelung der Druckverhältnisse unterhalb und oberhalb des Förderbandes Umführungskianäle seitlich des Kastens angebracht sind, durch welche die Trockengase bei Stauungen im überdruckraum mittels selbsttätig sich öffnender Durchlaßklappen in den Trockenraum umgeleitet werden.Another characteristic of the subject matter of the invention is that that to regulate the pressure conditions below and above the conveyor belt bypass channels are attached to the side of the box, through which the drying gases in the event of congestion in the overpressure room by means of automatically opening flaps in the drying room be redirected.
Die Trockenvorrichtung gemäß der Erfindung ist zum Trocknen für die -verschiedenartigsten Stoffe, insbesondere aber solcher stückiger Natur, geeignet. Die Ab.hebemesser haben den Vorteil der besseren Durchströmung der Trockengase durch das Band und das Gut sowie erhöhter Trockenwirkung. Durch die Anordnung der Umführungskanäle wird in einfacher Weise eine Regelung der verschiedenen Drücke und ein sicherer Betrieb erzielt.The drying device according to the invention is for drying for -Different types of substances, but especially those of lumpy nature, suitable. The lifting knives have the advantage that the drying gases can flow through better the tape and the goods as well as increased drying effect. Through the arrangement of the bypass channels is a simple way of regulating the various pressures and a safer one Operation achieved.
Der Trockner gemäß der Erfindung ist auf der Zeichnung an einem Ausführungsbeispiel schematisch dargestellt.The dryer according to the invention is shown in the drawing using an exemplary embodiment shown schematically.
Abb. i veranschaulicht einen Längsschnitt des Trockners und A.bb. 2 einen Ouerschnitt nach Linie A-B der A'bb. i.Fig. I illustrates a longitudinal section of the dryer and A.bb. 2 shows a cross section along line A-B of A'bb. i.
Unterhalb des umlaufenden Förder- und Trockenbandes i befindet sich der überdruckraum 2, welcher durch. die Kastenwand 3 und Tragrollen. und 5 mit deren Wänden6 und 7 umgrenzt wird. Oberhalb des Bandes i .ist der Trockenraum 8 vorgesehen, welcher an den Enden durch die Walzen. 9 und 1 o sowie durch die Trocknungsschicht i i abgeschlossen wird.Below the circulating conveyor and drying belt i is located the overpressure chamber 2, which through. the box wall 3 and support rollers. and 5 with theirs Walls 6 and 7 is delimited. The drying room 8 is provided above the belt i. which at the ends by the rollers. 9 and 1 o as well as through the drying layer i i is completed.
Oberhalb des Trockenraumes 8 -ist der Trockner bzw. Erhitzer 12 sowie der Staubscheider 13 angeordnet.Above the drying space 8 is the dryer or heater 12 as well the dust separator 13 is arranged.
Die Arbeitsweise der Einrichtung ist folgende: Die Trockengase werden vorn Erhitzer 12 durch die Leitung 14. zum Überdruckraum :2 geleitet und strömen von dort durch das Band i oder durch die Umführungskanäle 15 und Durchlaßklappen 16 zum Trockenrauen B.The operation of the device is as follows: The drying gases are front heater 12 through line 14 to the overpressure chamber: 2 and flow from there through the band i or through the bypass channels 15 and passage flaps 16 for drying B.
Die gesättigten Trockengase werden alsdann mittels Gebläses 17 vom Trockenraum 8 durch den Staubscheider 13 gesaugt und zur Entfeuchtung, Entlüftung und Wiedererwärmung in den Erhitzer 12 gebracht, von wo aus der Kreislauf von neuem beginnt.The saturated drying gases are then by means of fan 17 from Drying space 8 sucked through the dust separator 13 and used for dehumidification, ventilation and rewarming is brought into the heater 12, from where the cycle is renewed begins.
Auf dem Wege durch den Staubscheidzr werden mittels schraubenförmiger Ablenkbleche 18 die Staubteilchen der Trockengase abgesondert und durch Rutschen ig und 2o auf das Band zurückgeführt.On the way through the Staubscheidzr are by means of helical Deflectors 18 separate the dust particles from the dry gases and slide through them ig and 2o traced back to the tape.
Zur besseren Durchströmung der Trockengase und erhöhten Trocknung des Gutes sind auf dem Förderband i in Abständen Abliebemesser 21 vorgesehen.For better flow of drying gases and increased drying of the goods are provided on the conveyor belt i at intervals of clearance knives 21.
Die Reinigung des Bandes i erfolgt in einfacher Weise durch einen Gasstrahl (Preßluft, lösende Dämpfe usw.) oder durch einen Sand- oder Flüssigkeitsstrahl. Zu diesem Zwecke sind am Ende des Bandes die Leitungen 22 vorgesehen.The belt i is cleaned in a simple manner by a Gas jet (compressed air, dissolving vapors, etc.) or a sand or liquid jet. For this purpose, the lines 22 are provided at the end of the tape.
