Gegenstand vorliegender Erfindung bildet eine Neuerung an auf dem Gegenstromprincip beruhenden Einrichtungen zum Dämpfen und Imprägniren bezw. Trocknen von Holz und dergl., bei welchen die successive einer steigenden Temperatur zu unterwerfenden Holzmengen auf hinter einander angeordneten, durch den Dampfraum gleichzeitig fortschreitenden Transportvorrichtungen (Wagen) untergebracht sind, welche nach jedem Vorschub durch zwischen je zwei auf einander folgenden Dampfkammern angeordnete Schiebethüren, von einander getrennt werden können, so dafs ein directes Durchströmen des Dampfes verhindert wird.The subject matter of the present invention is an innovation based on the countercurrent principle Devices for steaming and impregnation respectively. Drying of wood and the like, in which the successive one increases Temperature to be subjected to quantities of wood arranged one behind the other, by the Steam room at the same time advancing transport devices (wagons) are accommodated, which after each feed through between two successive steam chambers arranged sliding doors, can be separated from each other, so that a direct Prevents the steam from flowing through.

Der Erfindung gemäfs wird die gewünschte Circulation des Dampfes durch die auf einander folgenden Holzmengen dadurch erzielt, dafs die Behälter, welche die Holztnengen aufnehmen und sie vortheilhafterweise unten und seitlich umschliefsen, mit biegsamen Rohrleitungen versehen sind, welche einerseits mit dem Innern des Behälters verbunden sind, andererseits an zu den einzelnen Dampf kammern führenden Kanälen angeschlossen werden können, so dafs nach Anschlufs der Rohrleitungen der Dampf gezwungen ist, seinen Weg durch die ganze in einem Behälter entsprechend untergebrachte Holzmenge zu nehmen, um sodann durch die biegsame Rohrverbindung in die nächste Kammer zu gelangen.According to the invention, the desired circulation of the steam through the one on top of the other The following quantities of wood are achieved by the fact that the containers that hold the quantities of wood and advantageously enclosed at the bottom and at the sides with flexible pipes are provided, which on the one hand are connected to the interior of the container, on the other hand can be connected to ducts leading to the individual steam chambers, so that after the pipelines have been connected, the steam is forced to make its way through the to take the whole amount of wood stored in a container in order to then to get through the flexible pipe connection into the next chamber.

In beiliegender Zeichnung ist eine Ausführungsform beispielsweise dargestellt, und zwar in Fig. ι im Längsschnitt,In the accompanying drawing, an embodiment is shown, for example, in FIG Fig. Ι in longitudinal section,

Fig. 2 im wagerechten Schnitt nach 2-2 der Fig. ι undFig. 2 in a horizontal section according to 2-2 of Fig. Ι and

Fig. 3 im senkrechten Schnitt nach 3-3 der Fig. i.Fig. 3 in vertical section according to 3-3 of Fig. I.

Der hier aus Mauerwerk hergestellte Dämpfofen A ist an den beiden Enden mittelst Thüren: A⁴ A⁵ abgeschlossen und durch Thüren A⁶ A¹ in mehrere (drei) Dampf kammern A¹ A? A³ getheilt. Die Thüren sind vortheilhaft Schiebethüren und können nach Bedarf herausgezogen werden. The steaming furnace A , made here of masonry, is closed at both ends by means of doors: A ⁴ A ⁵ and through doors A ⁶ A ¹ into several (three) steam chambers A ¹ A? A ³ divided. The doors are advantageously sliding doors and can be pulled out as needed.

Der Dämpfofen ist mit einem Geleise A¹⁰ versehen, über welches die vortheilhafterweise auf Rollwagen ruhenden, oben offenen, unten geschlossenen und dem Querschnitt des Ofens angepafsten Behälter E sich fortbewegen. Jeder Behälter ist mit einem perforirten Zwischenboden E¹ versehen und der Raum E² unterhalb desselben steht mit einem Kupplungsschlauch E³ durch einen seitlich angeordneten, gegen die Anschlufsstellen des Schlauches sich verengenden Kanal in Verbindung.The steaming furnace is provided with a track A ¹⁰ , over which the containers E , advantageously resting on trolleys, open at the top, closed at the bottom and adapted to the cross section of the furnace, move. Each container is provided with a perforated intermediate floor E ¹ and the space E ² below it is connected to a coupling hose E ³ through a laterally arranged channel which narrows towards the connection points of the hose.

Um ein gleichmäfsiges Durchströmen des Dampfes durch die ganze im Behälter aufgestapelte Holzmenge zu erzielen, sind die Oeffnungen in dem Boden E¹ gegen die Ausströmstelle zu kleiner und in gröfseren Abständen von einander angeordnet, wogegen der Querschnitt des Raumes E² in der Durchströmrichtung des Dampfes zunimmt.In order to achieve a uniform flow of the steam through the entire amount of wood stacked in the container, the openings in the bottom E ^{1 are} too small towards the outflow point and are arranged at greater distances from one another, whereas the cross-section of the space E ² increases in the direction of flow of the steam .

Jede Dampfkammer ist mit einer mittelst Thür F¹ verschliefsbaren, seitlichen Oeffnung F versehen, in welche von der benachbarten Kammer ein mittelst Hahnes F³ absperrbares Verbindungsrohr F² eingeführt ist, an welches der Kupplungsschlauch des in der Kammer befindlichen Behälters angeschlossen wird. DieEach steam chamber is provided with a side opening F which can be closed by means of a door F ¹ , into which a connecting pipe F ^2, which can be shut off by means of a cock F ³ and to which the coupling hose of the container located in the chamber is connected, is inserted from the adjacent chamber. the

Claims

The opening F must be sufficiently large and arranged in such a way that the coupling hose can be connected from the outside through it. The pipe F2 of the steam chamber A1, on the other hand, opens into the open and thus forms the outlet through which the steam and the escaping gases exit. In order to be able to move all containers forward simultaneously by a locomotive, if desired, couplings G G1 are provided for the cars, which can also be switched on and off from the outside through the opening F. A drain tap E * located on the floor is used to drain the juices and condensate water before impregnation. The impregnation liquid is let in by means of a line H passed through the ceiling of chamber A3 and provided with a valve H1. Advantageously, the individual steam chambers are also heated from the outside by a special heating device. The mode of operation of the device is as follows: The bezw to be dried. The material to be dampened and impregnated (wood) W is layered in the containers in such a way that free passages remain between the individual parts. In normal operations there is a container E in each chamber, which by means of the hose coupling Es and by connecting to the associated connecting line F2 with the next chamber respectively. in the end was brought into contact with the open air. All doors are closed, so that the steam entering at C and, in a correspondingly overheated state, reaches chamber Az through distributors C4. vertical direction goes down through the material piled up in container E and then passes through the coupling hose into the next steaming chamber and finally escapes from chamber A1 into the open. When the material in container A3, in which the highest temperature prevails, has dried sufficiently, the entry of steam is shut off and, if desired, the container is filled with impregnating liquid through line H, then all doors are opened, a fresh container E is backed up to the one in the Chamber A1 is connected and after uncoupling the hose E3 and closing the coupling G G1, the entire row of containers is advanced around a steam chamber in the direction towards A3, whereupon the process is repeated again after the doors have been closed. ■ "Patent claims:

2. Embodiment of the device according to claim i, for the purpose of achieving as uniform a steam flow as possible through the entire amount of wood piled up in the container, characterized in that the container is open at the top and provided with a perforated support base and that the space (E ² ) between The support base and the container base are connected to the coupling hose by a channel advantageously narrowing towards the connection point of the coupling hose, the perforations in the support base decreasing towards the outflow point, while the flow cross-section of the space (E ² ) increases.
