Abstract

The dryer has a number of e.g. roller-conveyors equal to its number of tiers. Encased nozzles (14a,14b) extend the width of the conveyors and have an inlet at one end, and a closed other end (18). Drying air is blown through the nozzle openings at least on one side of the material conveyed through. The encased nozzles are vertically movable at one end and are fixed in a slanting position in which the distance between the nozzle holes (16) and the conveyor plane on one side of the dryer is greater than on the other side.

Description

Die Erfindung betrifft einen Trockner für band- oder plattenförmiges Gut, insbesondere einen Mehretagentrockner für Gipskartonplatten, gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a dryer for strip or plate-shaped material, in particular a multi-floor dryer for plasterboard, according to the Preamble of claim 1.

Sie geht von einem Trockner aus, der durch die DE-OS 19 46 696 bekannt geworden ist. Die Druckschrift enthält schon deutliche Hinweise auf das Problem, auf der ganzen Breite der Fördereinrichtung eine gleichmäßige Trocknung zu erreichen. Hierzu sind verschiedene Maßnahmen vorgesehen. Die Düsenkästen sind keilförmig ausgebildet, so daß der Querschnitt von der Zuströmseite in Richtung auf das andere Ende abnimmt. Dadurch soll innerhalb des Düsenkastens auf der ganzen Länge ein konstanter Druck aufrechterhalten werden. Die keilförmigen Düsenkästen sind so angeordnet, daß der Abstand der Begrenzungswand, die der durchlaufenden Platte zugekehrt ist, von der Zuströmseite in Richtung auf die Abströmseite zunimmt. Dadurch wird der abströmenden Luft mit zunehmendem Abstand von der Zuströmseite ein entsprechend der zunehmenden Menge größer werdender Querschnitt zur Verfügung gestellt. Um trotz des ungleichmäßigen Abstandes zwischen Düsenkasten und durchlaufender Platte auf der ganzen Breite eine gleichmäßige Geschwindigkeit der auf die Platte aufprallenden Trocknungsluftstrahlen zu erhalten, sind die Düsen als kurze Rohrstücke ausgebildet, deren Länge um so größer ist, je weiter sie von der Zuströmseite entfernt angeordnet sind. Dadurch wird der Abstand zwischen Düsenmündung und durchlaufender Platte auf der ganzen Breite konstant gehalten. Eine weitere Maßnahme besteht darin, den Trockner in aufeinanderfolgende Zonen zu unterteilen und die Zuströmöffnungen der Düsenkästen von Zone zu Zone abwechselnd an gegenüberliegenden Seiten des Trockners anzuordnen.It is based on a dryer known from DE-OS 19 46 696 has become. The document already contains clear indications of the problem uniform drying over the entire width of the conveyor to reach. Various measures are provided for this. The nozzle boxes are wedge-shaped, so that the cross section from the inflow side in Towards the other end. This is supposed to be inside the nozzle box constant pressure is maintained along the entire length. The wedge-shaped nozzle boxes are arranged so that the distance of the Boundary wall facing the continuous plate from the inflow side increases towards the downstream side. This will make the outflow Air with increasing distance from the inflow side according to the increasing amount of increasing cross section provided. Around despite the uneven distance between the nozzle box and the continuous one Plate across the entire width of a uniform speed of the plate to get impinging jets of drying air, the nozzles are short Pipe pieces formed, the length of which is greater, the further they are from the Inflow side are arranged away. This will make the distance between the nozzle mouth and continuous plate kept constant over the entire width. A Another measure is to move the dryer into successive zones divide and the inlet openings of the nozzle boxes from zone to zone to be arranged alternately on opposite sides of the dryer.

Die zuletzt genannte Maßnahme setzt bei den üblicherweise in Gipskartonplattentrocknem eingesetzten Rollenförderem voraus, daß sowohl die Antriebe mit den Antriebsketten als auch die Versorgungsleitungen in aufeinanderfolgenden Zonen auf entgegengesetzten Seiten angeordnet sind. Daher wechselt auch die für Wartungs- oder Reparaturarbeiten zugängliche Seite von Zone zu Zone. Das ist in der Praxis ein schwerer Nachteil. Schon der Umstand, daß in der erwähnten Druckschrift diese Maßnahme trotzdem empfohlen wird, deutet darauf hin, daß die übrigen Maßnahmen nicht die gewünschte Gleichförmigkeit auf der ganzen Breite gewährleisten.The last-mentioned measure sets in the usually in plasterboard dryers used roller conveyor that both the drives with the Drive chains as well as the supply lines in successive zones are arranged on opposite sides. Therefore, the changes for Maintenance or repair work accessible side from zone to zone. Is in a serious disadvantage in practice. The very fact that in the mentioned publication this measure is nevertheless recommended, indicates that the other measures do not achieve the desired uniformity across the entire width guarantee.

Die ungleichförmige Trocknung wird in besonders starkem Maße bei Trocknem beobachtet, die - wie der in der angeführten Druckschrift beschriebene Trockner - mehrere etagenartig übereinander angeordnete Fördereinrichtungen aufweisen und aus diesem Grunde einen sehr kompakten Aufbau haben. Die Querschnittsabmessungen der einzelnen Düsenkästen sind dabei sehr klein im Verhältnis zur Länge. Es kann sich - in Längsrichtung des Düsenkastens gesehen - eine ungleichmäßige Verteilung der Geschwindigkeit ergeben, mit der die Luftstrahlen aus den Düsenöffnungen ausströmen. Durch die in Querrichtung abströmende Luft werden die Düsenstrahlen mit zunehmender Entfernung von der Zuströmseite immer stärker aus der Vertikalen abgelenkt.. Die zwischen den Düsenkästen abströmende Luft bewirkt eine in Richtung auf die Abströmseite zunehmende Kühlung der Düsenkästen, die zu einer Abkühlung der Trocknungsluft und letzten Endes zu einer Verschlechterung des Trocknungseffektes führt.The non-uniform drying is particularly strong when drying observed that - like the dryer described in the cited publication - have a plurality of conveyor devices arranged one above the other in a tier and therefore have a very compact structure. The cross-sectional dimensions of the individual nozzle boxes are very small in relation to the Length. It can - seen in the longitudinal direction of the nozzle box - one give an uneven distribution of the speed at which the air jets flow out of the nozzle openings. Due to the outflow in the transverse direction The air jets become air with increasing distance from the inflow side distracted more and more from the vertical .. The one between the nozzle boxes outflowing air causes an increase in the direction of the outflow side Cooling of the nozzle boxes, which leads to a cooling of the drying air and last Ultimately leads to a deterioration in the drying effect.

Die in der Druckschrift angegebenen Maßnahmen haben außerdem den Nachteil, daß sie nur schwer korrigierbar sind, wenn sich herausstellt, daß die erforderliche Gleichmäßigkeit nicht ereicht wird.The measures specified in the publication also have the disadvantage that that they are difficult to correct if it turns out that the required Uniformity is not achieved.

Der Erfindung liegt die Aufgabe zugrunde, einen Trockner mit den im Oberbegriff angegebenen Merkmalen mit einfachen Mitteln auszustatten, die es ermöglichen, auf der gesamten Breite eine gleichmäßige Restfeuchte zu erhalten und etwaige Abweichungen mit geringem Aufwand zu korrigieren. Diese Aufgabe wird durch die kennzeichnenden Merkmale des Anspruchs 1 gelöst.The invention has for its object a dryer with the in the preamble to equip the specified features with simple means that make it possible to maintain a uniform residual moisture over the entire width and any Correct deviations with little effort. This task is accomplished by the characterizing features of claim 1 solved.

Bei der Erfindung macht man sich den Umstand zunutze, daß der Wärmeübergang von einem aufprallenden Luftstrom auf eine zu trocknende Platte eine Funktion des Abstandes zwischen Düsenmündung und Platte ist.The invention takes advantage of the fact that the heat transfer a function of an impinging air flow on a plate to be dried of the distance between the nozzle mouth and the plate.

Weitere vorteilhafte Merkmale der Erfindung sind in den Ansprüchen 2 bis 3 angegeben. Further advantageous features of the invention are in claims 2 to 3 specified.

Der Trockner besteht z. B. aus dreißig oder mehr baukastenartig aneinandergereihten Abteilen. Ein Abteil misst in Förderrichtung 2,0 m bis 2,5 m und ist 5,0 m bis 6,0 m breit. Es hat eine Decke 1 und Seitenwände 2, 3.The dryer consists e.g. B. from thirty or more modularly lined up Compartments. A compartment measures 2.0 m to 2.5 m in the direction of conveyance and is 5.0 m up to 6.0 m wide. It has a ceiling 1 and side walls 2, 3.

In dem Abteil ist durch eine Zwischendecke 4, eine Trennwand 5 und ein gitterartiges Traggestell 6 ein Kernbereich 7 von einem Umluftkanal abgetrennt. Dieser besteht aus einem waagerechten Kanal 8 über dem Kernbereich 7, einem seitlichen senkrechten Verteilerkanal 9 und einem auf der gegenüberliegenden Seite im wesentlichen spiegelsymmetrisch angeordneten Sammelkanal 10. Die Breite des Kembereichs 7 beträgt etwa 50 bis 65 % der Gesamtbreite, die Höhe etwa 60 bis 80 % der Gesamthöhe. In dem Kernbereich 7 sind in mehreren Ebenen, in der Praxis in etwa acht bis zwölf Ebenen, die in gleichen Abständen von etwa 250 bis 350 mm etagenartig übereinanderliegen, Rollen 11 angeordnet, die an der einen Seite an der Trennwand 5, an der anderen Seite in dem Traggestell 6 gelagert sind. An dem Ende, das dem Traggestell 6 benachbart ist, hat jede Rolle 11 einen Zapfen 12, auf dem ein Kettenrad 13 sitzt Über nicht dargestellte Ketten sind alle Rollen 11 mit der gleichen Geschwindigkeit antreibbar. In the compartment is through a false ceiling 4, a partition 5 and a grid-like support frame 6, a core area 7 separated from a recirculation duct. This consists of a horizontal channel 8 over the core area 7, one lateral vertical distribution channel 9 and one on the opposite Side essentially mirror-symmetrically arranged collecting duct 10. Die Width of core area 7 is approximately 50 to 65% of the total width, the height about 60 to 80% of the total height. In the core area 7 are in several Levels, in practice at about eight to twelve levels, which are equidistant from about 250 to 350 mm above one another, rollers 11 arranged, the one side on the partition 5, on the other side in the Support frame 6 are stored. At the end that is adjacent to the support frame 6 each roller 11 has a pin 12 on which a sprocket 13 is not seated chains shown, all rollers 11 can be driven at the same speed.

Sie bilden daher in jeder Etage einen Rollenförderer, der sich über die gesamte Länge des Trockners erstreckt.They therefore form a roller conveyor on each floor that spans the entire floor Length of the dryer extends.

Unterhalb und oberhalb der Transportebenen, in denen sich die auf den einzelnen Rollenförderem liegenden Platten kontinuierlich durch den Trockner bewegen, sind in den Zwischenräumen nebeneinanderliegender Rollen 11 fingerartige Düsenkästen 14a, 14b angeordnet, die sich über die Breite des Rollenförderers erstrecken. Die der Transportebene zugekehrte Begrenzungswand des Düsenkastens 14a, 14b ist mit Düsenöffnungen 15 zum Aufblasen von Trocknungsluft auf die durchlaufenden Platten 16 versehen. Das eine Ende des Düsenkastens 14a, 14b ist als Zuströmöffnung 17 ausgebildet, das andere Ende 18 ist geschlossen. Die Düsenkästen 14a, 14b sind keilförmig ausgebildet, so daß ihr Querschnitt in Richtung auf das geschlossene Ende 18 stetig abnimmt. Zwischen benachbarten Transportebenen ist jeweils ein oberer Düsenkasten 14a mit einem unmittelbar darunterliegenden Düsenkasten 14b hosenartig verbunden, so daß sie einen Doppelkasten bilden und eine gemeinsame Einströmöffnung 17 haben. Das Ende, an dem sich die Einströmöffnung 17 befindet, sitzt passend in einer rechteckigen Ausnehmung der Trennwand 5. Es ist unbeweglich an der Trennwand 5 befestigt und durch einen in Figur 4a erkennbaren abgewinkelten Kragen ringsum abgedichtet. Am anderen Ende 18 des Düsenkastens 14a, 14b ist eine hochkant angeordnete Halteplatte 19 befestigt.Below and above the transport levels, in which the individual Roller conveyors are continuously moving through the dryer in the spaces between adjacent rollers 11 finger-like Nozzle boxes 14a, 14b arranged which extend across the width of the roller conveyor extend. The boundary wall of the Nozzle box 14a, 14b is provided with nozzle openings 15 for inflating Provide drying air on the continuous plates 16. One end of the Nozzle box 14a, 14b is designed as an inflow opening 17, the other end 18 is closed. The nozzle boxes 14a, 14b are wedge-shaped, so that their cross-section decreases steadily in the direction of the closed end 18. There is an upper nozzle box 14a between adjacent transport levels connected to a nozzle box 14b directly underneath, like pants, so that they form a double box and a common inflow opening 17th to have. The end at which the inflow opening 17 is located fits in a rectangular recess of the partition 5. It is immobile on the Partition 5 attached and by an angled recognizable in Figure 4a Collar sealed all around. At the other end 18 of the nozzle box 14a, 14b an upright holding plate 19 attached.

Der waagerechte Kanal 8 ist durch ein treppenstufenähnlich geformtes Trennblech 20 in einen Saugraum 21 und einen Druckraum 22 unterteilt. Der Saugraum 21 steht mit dem Sammelkanal 8 in offener Verbindung, der Druckraum 22 mit dem Verteilerkanal 9. Mittig in dem waagerechten Kanal 8, und zwar in dem durch das Trennblech 20 abgetrennten Druckraum 22, ist ein freilaufendes (d. h. gehäuseloses) einseitig saugendes Radiallaufrad 23 untergebracht, dessen Antriebswelle die Decke 1 durchdringt und mit einem auf der Decke 1 sitzenden Antrieb 24 gekoppelt ist. Mit dem Ansaugtrichter 25 des Radiallaufrades 23 korrespondiert eine Öffnung in einem horizontalen Bereich des Trennblechs 20, so daß das Radiallaufrad 23 saugseitig mit dem Saugraum 21 in Verbindung steht. The horizontal channel 8 is formed by a partition plate shaped like a stair step 20 divided into a suction chamber 21 and a pressure chamber 22. The suction space 21 is in open connection with the collecting duct 8, the pressure chamber 22 with the Distribution channel 9. Center in the horizontal channel 8, in the through the Baffle 20 separated pressure space 22 is a free-running (i.e. houseless) one-sided suction radial impeller 23, whose Drive shaft penetrates the ceiling 1 and with one sitting on the ceiling 1 Drive 24 is coupled. With the suction funnel 25 of the radial impeller 23 corresponds to an opening in a horizontal region of the separating plate 20, so that the radial impeller 23 is connected on the suction side to the suction chamber 21.

Die Halteplatte 19 ist mit einem senkrechten Langloch 26 versehen. Durch zwei Schrauben 27, die durch das Langloch 26 hindurchgreifen, ist die Halteplatte 19 mit einem Schenkel eines U-ähnlich geformten Befestigungselementes 28 verbunden. Der andere Schenkel ist an einem waagerechten Träger 29 des Traggestells 6 befestigt. Das Langloch 26 erlaubt in senkrechter Richtung eine Verschiebung, wie durch einen Doppelpfeil in Figur 5 symbolisiert.The holding plate 19 is provided with a vertical slot 26. Divided by two Screws 27 which reach through the elongated hole 26 are the holding plate 19 a leg of a U-like shaped fastener 28 connected. The other leg is on a horizontal support 29 of the support frame 6 attached. The slot 26 allows a displacement in the vertical direction, such as symbolized by a double arrow in FIG. 5.

Bei dem beschriebenen Ausführungsbeispiel, bei dem die Düsenöffnungen 15 gemäß Figur 3 als kreisrunde Löcher ausgebildet sind, ist auf der Seite, an der die Zuströmöffnung 17 angeordnet ist, der Abstand zwischen den Düsenöffnungen 15 und der durchlaufenden Platte 16 etwa gleich dem 4- bis 5-fachen Lochdurchmesser. An der Seite, an der sich das geschlossene Ende 18 befindet, läßt er sich auf etwa den 2,5 bis 4-fachen Lochdurchmesser verkleinern. Bei einem Lochdurchmesser von 1,0 bis 1,5 cm beträgt also die Verschiebung maximal etwa 3,0 cm. Die Düsenkästen 14a, 14b sind bei einer Länge von etwa 3,0 m in dem für die Verschiebung erforderlichen Maß elastisch verformbar.In the described embodiment, in which the nozzle openings 15 3 are designed as circular holes, is on the side where the Inflow opening 17 is arranged, the distance between the nozzle openings 15 and the continuous plate 16 approximately equal to 4 to 5 times Hole diameter. On the side where the closed end 18 is located it can be reduced to about 2.5 to 4 times the hole diameter. At a Hole diameters from 1.0 to 1.5 cm, the maximum displacement is approximately 3.0 cm. The nozzle boxes 14a, 14b are approximately 3.0 m long the displacement required dimension elastically deformable.

Die Einstellung der Düsenkästen 14a, 14b erfolgt bei der Montage, und Inbetriebnahme des Trockners. Wenn alle Düsenkästen 14a, 14b so montiert sind, dass die Düsenöffnungen 15 auf der gesamten Breite den gleichen Abstand von den durchlaufenden Platten haben, stellt man in der Regel fest, dass die Platten auf der Seite, an der die Zuströmöffnung 17 angeordnet ist, trockener sind als auf der Seite, an der sich das geschlossene Ende 18 befindet. Zeckmäßig werden die Düsenkästen 14a, 14b schon bei der Montage nach einer Modellrechnung oder nach Erfahrungswerten ein wenig schräg gestellt, so dass an der Seite, an der sich das geschlossene Ende 18 befindet, der Abstand der Düsenöffnungen 15 von der durchlaufenden Platte 16 kleiner ist als auf der Seite, an der die Zuströmöffnung 17 angeordnet ist. Die oberen Düsenkästen 14a in Figur 4 werden daher mit einem leichten Gefälle nach links, die unteren Düsenkästen 14b mit einem leichten Gefälle nach rechts montiert. Bei Trocknem, die aus einer größeren Anzahl von aneinandergereihten Abteilen bestehen, wird die Schrägstellung zumindest in einigen Abteilen vorgenommen, vorzugsweise in der einlauf-seitigen Hälfte der Trocknungsstrecke. Zeigt sich dann bei der Inbetriebnahme, dass die Restfeuchte der den Trockner verlassenden Platten auf der einen Seite größer oder kleiner ist als auf der anderen Seite, so wird je nach Größe der festgestellten Ungleichförmigkeit eine Korrektur vorgenommen. Dies geschieht, indem man weitere Düsenkästen ein wenig schräg oder bei dem bereits schräggestellten Düsenkästen die Neigung vergrößert, verkleinert oder rückgängig macht.Je nach der Größe der festgestellten Ungleichförmigkeit genügt es schon, nur bei wenigen Düsenkästen, z. B. bei den Düsenkästen eines einzigen Abteils, die Schrägstellung zu korrigieren. Nach der Durchführung der Korrektur sind die Düsenkästen daher in der Regel in unterschiedlichen Stellungen arretiert.The nozzle boxes 14a, 14b are adjusted during assembly, and Commissioning the dryer. When all the nozzle boxes 14a, 14b are assembled that the nozzle openings 15 have the same distance over the entire width the continuous plates, it is usually found that the plates are on the side on which the inflow opening 17 is arranged are drier than on the Side on which the closed end 18 is located. The ticks are Nozzle boxes 14a, 14b already during assembly according to a model calculation or according to experience a little slanted so that on the side to which the closed end 18 is the distance of the nozzle openings 15 from the continuous plate 16 is smaller than on the side on which the inflow opening 17th is arranged. The upper nozzle boxes 14a in Figure 4 are therefore with a slight slope to the left, the lower nozzle boxes 14b with a slight slope mounted to the right. When dry, which consists of a larger number of lined up compartments exist, the inclination is at least in some compartments, preferably in the inlet-side half of the Drying section. Then shows during commissioning that the residual moisture the plates leaving the dryer are larger or smaller on one side than on the other side, depending on the size of the found Non-uniformity made a correction. This is done by further nozzle boxes a little slanted or with the one already slanted Nozzle boxes the incline increases, decreases or reverses, depending on the size of the observed non-uniformity is sufficient, only for a few Nozzle boxes, e.g. B. in the nozzle boxes of a single compartment, the inclination to correct. After performing the correction, the nozzle boxes are therefore in usually locked in different positions.
