Definitions
- the invention relates to a dryer for perforated ceramic moldings, preferably perforated bricks, with einbringbaren, successive and possibly juxtaposed stackable dry goods carriers having provided with supporting elements storage locations for supporting the mold, wherein dry air is directed directed against the perforated surface of the moldings.
- the invention also relates to a method for drying perforated ceramic moldings, which are deposited on storage locations of stackable dry material carriers in a dryer.
- EP 89 408 B1 already discloses a device for venting provided with air channels dry matter in a tunnel dryer, in which only a single layer of brick blanks is arranged in the dryer. But here too complex deflection devices are needed to dry the bricks. The stocking of the dryer is extremely low for the circulation of the dry air is required per dried brick very much energy.
- the invention has for its object to further develop a dryer for perforated ceramic moldings and a method for drying perforated ceramic moldings so that in a very large stocking uniform drying with low energy consumption per dried brick is achieved.
- each dry-material carrier has at least one row of filing points and each filing row of support elements for at least two moldings, wherein the dry-material carrier parallel to the filing-row row arranged on both sides, frontally opposite each closed air ducts and wherein the respective one air duct with its open End connected to the dry air supply and the second air duct is connected with its open end with the air discharge.
- each dry load carrier at least two substantially mutually parallel rows of storage locations and between the filing rows arranged shipsleitkanäle, said disposed between the filing rows air ducts are divided by vertically arranged separating elements in two on each side opposite closed air ducts and the each a sub-channel to the dry air supply is connected and the respective second sub-channel is connected to the air discharge.
- each dry goods carrier can carry a large number of moldings, no series of moldings takes place.
- Each dry goods carrier has its own air ducts over which the dry air is directed against the perforated end faces of the moldings.
- no expensive louvers must be provided in the dryer itself.
- a very large stocking in the dryer is possible and each mold is flowed through by the dry air of the same nature, so that all moldings dry the same time at the same time.
- the advantage is that the filing system rows are each closed on the face side. This ensures that only the openings of the channels air can absorb the dry air fan out. Transverse air over the moldings is prevented by the closed end faces of the shelf rows.
- a particularly simple structure results when the separating elements bisect the air duct diagonally. This ensures that always enough and therefore the same dry air can be passed to all bricks and also the humidified air can be discharged according to the same. In addition, due to the diagonal arrangement of the separating elements, a higher stability results and the least amount of material is guaranteed.
- each storage place row closed at least on one side nozzle walls having bulkheads to the air duct ensures that in the air duct a corresponding back pressure can occur, so that the moldings can all be supplied with the same dry air via the nozzles.
- the number of nozzles should correspond at least to the number of holes of the moldings to be dried. Preferably, however, the number of nozzles should be higher than that of the holes of the moldings to be dried, in order to ensure that the end faces of the moldings, in the region of which there are no holes, are accordingly exposed to dry air.
- the bulkhead is designed as a perforated plate.
- the holes of the perforated plate form the simplest forms of nozzles, so that the creation of the bulkhead is very cost-effective.
- the holes of the perforated plates are aligned at least on the perforations having front sides of the moldings, it is ensured that each molding is applied over the entire surface with dry air. It is advantageous, however, if the surface of the holes is larger than the end face of the moldings, so that even on the sides in the area of the supports and above and laterally of the moldings drying air can stroke along.
- the dry goods carrier is closed at least on the underside. This ensures that the flow in the litter stock actually takes place essentially through the moldings to be dried and not additionally in the dryer from bottom to top through the dry material carrier.
- the support elements on which the moldings are placed are aligned substantially at right angles to the air duct ensures that the support elements of the dry air barely oppose a resistance. This optimal drying of the bottom of the moldings is possible.
- Fig. 1 Of the Fig. 1 is to remove a dryer 1, in which a dryer car 2 is arranged, which carries a number of dry material carriers 3. Above the upper dry goods carrier 3 ', a fan 4 can be seen, over the dry air, a flow direction A is issued. At predetermined time intervals or eg after measuring the moisture differences in the moldings 5 on the dry material carriers 3, the fan 4 can reverse the flow direction, so that then the flow direction according to arrow B in the dryer 1 prevails.
- Fig. 2 shows a dry material carrier 3, the support elements 8, which represent the storage location for the moldings 5.
- the moldings 5 have right and left holes 9, 9 ', which are connected to each other via tubes 10.
- the number of moldings in a row is adjusted according to the size of the dryer.
- Between the filing rows 11 Vietnameseleitkanäle 12 are arranged, which are divided into two by diagonal separating elements 13.
- the filing-row 11 are separated from the air ducts 12 by perforated plates 14.
- the perforated plates 14 cause that in the air ducts 12, in which the dry air is injected, a back pressure arises, which in turn ensures the most uniform possible loading of the moldings 5 with dry air.
- At the two outer ends of the dry material carrier only one shipsleitteilkanal 12 a, 12 b is provided in each case.
- Fig. It can be seen that a large stocking with moldings 5 is possible by the invention, arranged in the dry material carriers 3 Vietnameseleitkanälen 12, and that in the dryer 1 itself no complex structures for an air duct are necessary, so that the dryer 1 without More can be used for other tasks.
Abstract
Description
Die Erfindung betrifft einen Trockner für gelochte Keramikformlinge, vorzugsweise Hochlochziegel, mit einbringbaren, aufeinander und ggf. nebeneinander stapelbaren Trockengutträgern, die mit Stützelementen versehene Ablagestellen zur Auflage der Formliege aufweisen, wobei Trockenluft gegen die mit Lochungen versehene Oberfläche der Formlinge gerichtet geführt ist. Die Erfindung betrifft zudem ein Verfahren zum Trocknen gelochter Keramikformlinge, die auf Ablagestellen von übereinander stapelbaren Trockengutträgern in einem Trockner abgelegt sind.The invention relates to a dryer for perforated ceramic moldings, preferably perforated bricks, with einbringbaren, successive and possibly juxtaposed stackable dry goods carriers having provided with supporting elements storage locations for supporting the mold, wherein dry air is directed directed against the perforated surface of the moldings. The invention also relates to a method for drying perforated ceramic moldings, which are deposited on storage locations of stackable dry material carriers in a dryer.
Aus der
Als nachteilig hat sich jedoch erwiesen, dass hier mehrere Lagen von Formlingen in Luftströmungsrichtung hintereinander angeordnet sind, so dass die in Luftströmungsrichtung hinteren Formlinge nur durch die bereits angefeuchtete Trockenluft der zuvor getrockneten Formlinge beaufschlagt werden, wodurch die in Luftströmungsrichtung hinteren Formlinge schlechter trocknen als die zuerst von der Trockenluft beaufschlagten Formlinge. Es sollen zudem nur wenige Lagen der Formlinge hintereinander geschaltet werden, damit noch eine halbwegs schnelle und gute Trocknung erfolgt. Dadurch lässt sich nur ein sehr kleiner Besatz pro Trockner trocknen. Hinzu kommt, dass im Trockner aufwendige Bauten für die Umlenkung der Trockenluft auf die Stirnseiten der gelochten Formlinge notwendig sind.However, it has proved to be disadvantageous that several layers of molded articles are arranged behind one another in the direction of air flow, so that the molded articles which are already damped in the air flow direction are only exposed to the already dried dry air of the previously dried molded articles, as a result of which the rear molded articles in the air flow direction dry worse than the first from the dry air acted on moldings. In addition, only a few layers of the moldings are to be connected in series, so that even a reasonably quick and good drying takes place. This allows only a very small stock per dryer dry. In addition, in the dryer complex structures for the deflection of the dry air on the front sides of the perforated moldings are necessary.
Auch die
Der Erfindung liegt die Aufgabe zugrunde, einen Trockner für gelochte Keramikformlinge sowie ein Verfahren zum Trocknen gelochter Keramikformlinge so weiter zu bilden, dass bei einem sehr großen Besatz eine gleichmäßige Trocknung bei geringem Energieverbrauch pro getrocknetem Ziegel erreicht wird.The invention has for its object to further develop a dryer for perforated ceramic moldings and a method for drying perforated ceramic moldings so that in a very large stocking uniform drying with low energy consumption per dried brick is achieved.
Dazu wird vorgeschlagen, dass jeder Trockengutträger mindestens eine Reihe von Ablagestellen und jede Ablagestellen-Reihe Stützelemente für mindestens zwei Formlinge besitzt, wobei der Trockengutträger parallel zur Ablagenstellen-Reihe beidseitig angeordnete, stirnseitig jeweils gegenüberliegend geschlossene Luftleitkanäle aufweist und wobei der jeweils eine Luftleitkanal mit seiner offenen Stirnseite an die Trockenluftzufuhr angeschlossen und der jeweils zweite Luftleitkanal mit seiner offenen Stirnseite mit der Luftabfuhr verbunden ist.For this purpose, it is proposed that each dry-material carrier has at least one row of filing points and each filing row of support elements for at least two moldings, wherein the dry-material carrier parallel to the filing-row row arranged on both sides, frontally opposite each closed air ducts and wherein the respective one air duct with its open End connected to the dry air supply and the second air duct is connected with its open end with the air discharge.
Zweckmäßig ist, wenn jeder Trockengutträger mindestens zwei im Wesentlichen parallel zueinander angeordnete Reihen von Ablagestellen sowie zwischen den Ablagestellen-Reihen angeordnete Luftleitkanäle aufweist, wobei die zwischen den Ablagestellen-Reihen angeordneten Luftleitkanäle durch senkrecht angeordnete Trennelemente in zwei einseitig jeweils gegenüberliegend geschlossenen Luftleitkanäle geteilt sind und der jeweils eine Teilkanal an der Trockenluftzufuhr angeschlossen ist und der jeweils zweite Teilkanal mit der Luftabfuhr verbunden ist.It is expedient if each dry load carrier at least two substantially mutually parallel rows of storage locations and between the filing rows arranged Luftleitkanäle, said disposed between the filing rows air ducts are divided by vertically arranged separating elements in two on each side opposite closed air ducts and the each a sub-channel to the dry air supply is connected and the respective second sub-channel is connected to the air discharge.
Dadurch ist gewährleistet, dass, obwohl jeder Trockengutträger eine große Anzahl von Formlingen tragen kann, keine Hintereinanderschaltung von Formlingen erfolgt. Jeder Trockengutträger weist eigene Luftleitkanäle auf, über die die Trockenluft gegen die gelochten Stirnflächen der Formlinge gerichtet wird. Im Trockner selbst müssen keine aufwendigen Luftleitvorrichtungen vorgesehen werden. Dadurch wird ein sehr großer Besatz im Trockner möglich und jeder Formling wird von der Trockenluft gleicher Beschaffenheit durchströmt, so dass alle Formlinge auch zur gleichen Zeit gleich trocknen.This ensures that, although each dry goods carrier can carry a large number of moldings, no series of moldings takes place. Each dry goods carrier has its own air ducts over which the dry air is directed against the perforated end faces of the moldings. In the dryer itself no expensive louvers must be provided. As a result, a very large stocking in the dryer is possible and each mold is flowed through by the dry air of the same nature, so that all moldings dry the same time at the same time.
Von Vorteil ist, dass die Ablagestellen-Reihen jeweils stirnseitlich geschlossen sind. Dadurch wird erreicht, dass zum Trockenluftventilator hin nur die Öffnungen der Kanäle Luft aufnehmen können. Querluft über die Formlinge wird durch die geschlossenen Stirnseiten der Ablagenstellen-Reihen verhindert.The advantage is that the filing system rows are each closed on the face side. This ensures that only the openings of the channels air can absorb the dry air fan out. Transverse air over the moldings is prevented by the closed end faces of the shelf rows.
Ein besonders einfacher Aufbau ergibt sich, wenn die Trennelemente den Luftleitkanal diagonal zweiteilen. Dadurch ist gewährleistet, dass stets genügend und damit gleiche Trockenluft an alle Ziegel geführt werden kann und auch die angefeuchtete Luft entsprechend gleich abgeführt werden kann. Hinzu kommt, dass durch die diagonale Anordnung der Trennelemente sich eine höhere Stabilität ergibt und der minimalste Materialaufwand gewährleistet ist.A particularly simple structure results when the separating elements bisect the air duct diagonally. This ensures that always enough and therefore the same dry air can be passed to all bricks and also the humidified air can be discharged according to the same. In addition, due to the diagonal arrangement of the separating elements, a higher stability results and the least amount of material is guaranteed.
Wird jede Ablagenstellen-Reihe mindestens einseitig über Düsen aufweisende Schottwände zum Luftleitkanal geschlossen ist gewährleistet, dass im Luftleitkanal ein entsprechender Staudruck entstehen kann, so dass über die Düsen die Formlinge alle gleich mit Trockenluft versorgt werden können.If each storage place row closed at least on one side nozzle walls having bulkheads to the air duct ensures that in the air duct a corresponding back pressure can occur, so that the moldings can all be supplied with the same dry air via the nozzles.
Dabei sollte die Anzahl der Düsen mindestens der Anzahl der Löcher der zu trocknenden Formlinge entsprechen. Vorzugsweise sollte die Anzahl der Düsen jedoch höher sein als die der Löcher der zu trocknenden Formlinge, damit sichergestellt ist, dass auch die Stirnseiten der Formlinge, in deren Bereich keine Löcher vorhanden sind entsprechend mit Trockenluft beaufschlagt werden.The number of nozzles should correspond at least to the number of holes of the moldings to be dried. Preferably, however, the number of nozzles should be higher than that of the holes of the moldings to be dried, in order to ensure that the end faces of the moldings, in the region of which there are no holes, are accordingly exposed to dry air.
Es hat sich bewährt, dass die Schottwand als Lochblech ausgebildet ist. Die Löcher des Lochblechs bilden die einfachsten Formen von Düsen, so dass die Erstellung der Schottwand sehr kostengünstig ist.It has been proven that the bulkhead is designed as a perforated plate. The holes of the perforated plate form the simplest forms of nozzles, so that the creation of the bulkhead is very cost-effective.
Sind die Löcher der Lochbleche zumindest auf die Lochungen aufweisenden Stirnseiten der Formlinge ausgerichtet, so ist gewährleistet, dass jeder Formling ganzflächig mit Trockenluft beaufschlagt wird. Vorteilhaft ist jedoch, wenn die Fläche der Löcher größer als die Stirnfläche der Formlinge ist, so dass auch noch an den Seiten im Bereich der Auflagen und oberhalb sowie seitlich der Formlinge Trockenluft entlang streichen kann.If the holes of the perforated plates are aligned at least on the perforations having front sides of the moldings, it is ensured that each molding is applied over the entire surface with dry air. It is advantageous, however, if the surface of the holes is larger than the end face of the moldings, so that even on the sides in the area of the supports and above and laterally of the moldings drying air can stroke along.
Besonders zweckmäßig ist, wenn der Trockengutträger zumindest unterseitig geschlossen ist. Damit wird erreicht, dass die Strömung im Haufwerksbesatz tatsächlich im Wesentlichen durch die zu trocknenden Formlinge und nicht zusätzlich im Trockner von unten nach oben durch die Trockengutträger erfolgt.It is particularly expedient if the dry goods carrier is closed at least on the underside. This ensures that the flow in the litter stock actually takes place essentially through the moldings to be dried and not additionally in the dryer from bottom to top through the dry material carrier.
Wenn die Luftleitkanäle oberseitig geschlossen sind ergeben sich komplett geschlossene Luftleitkanäle die besonders wirkungsvoll die Trockenluft an die Formlinge heran und von diesen abführen können. Die Ablagestellen sind dabei freigelassen, so dass diese leicht mit den Formlingen beladen werden können.If the air ducts are closed on the top side, completely closed air ducts are obtained, which are particularly effective in drawing the dry air to and from the moldings. The filing points are released, so that they can be easily loaded with the moldings.
Wenn die Stützelemente, auf denen die Formlinge abgelegt werden im Wesentlichen im rechten Winkel zum Luftleitkanal ausgerichtet sind ist gewährleistet, dass die Stützelemente der Trockenluft kaum einen Widerstand entgegensetzen. Damit ist eine optimale Trocknung auch der Unterseite der Formlinge möglich.If the support elements on which the moldings are placed are aligned substantially at right angles to the air duct ensures that the support elements of the dry air barely oppose a resistance. This optimal drying of the bottom of the moldings is possible.
Von besonderem Vorteil ist, wenn die Luftströmungsrichtung im Trockner während der Trocknung der Formlinge umgekehrt wird. Dadurch wird erreicht, dass jeder Formling abwechselnd von seinen beiden Seiten mit der trockenen Luft beaufschlagt werden kann, so dass der Formling im Wesentlichen homogen getrocknet wird. Ein Trocknungsgefälle im Formling von der einströmenden Trockenluft zur aus dem Formling ausströmenden Trockenluft wird damit optimal vermieden.It is particularly advantageous if the direction of air flow in the dryer is reversed during the drying of the moldings. This ensures that each molding can be alternately acted upon from its two sides with the dry air, so that the molding is dried substantially homogeneously. A drying gradient in the molding from the inflowing dry air to the outflowing from the molding dry air is thus optimally avoided.
