Description
KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Bei den bekannten Trockenschränken, insbesondere bei Vakuumtrockenschränken mit flachen, hohlen Heizkörpern, welche mit Dampf, Wasser und dergl. beheizt werden, besteht der Uebelstand, dafs eine durchaus gleichmä'fsige Erwärmung der Heizkörper nicht mit Sicherheit und Zuverlässigkeit zu erreichen ist. Der Hauptgrund hierfür ist darin zu suchen, dafs durch Ansammlung abgesperrter Luft oder von Condenswasser der eine oder der andere Heizkörper weniger Dampf erhält, oder dafs einzelne Stellen der Platten weniger heifs werden. Bei den Trockenschränken mit flüssigem Heizmittel ist die gleichmäfsige Füllung besonders schwierig, weil hier Luftsäcke entstehen, welche isolirend wirken und die Erwärmung aufserordentlich beeinträchtigen; auch unbeabsichtigtes Abweichen von der wagerechten Lage der Heizkörper wirkt leicht nachtheilig. In the known drying cabinets, especially in the case of vacuum drying cabinets flat, hollow radiators, which are heated with steam, water and the like, there is the disadvantage that a thoroughly uniform heating of the radiators is not possible can be achieved with safety and reliability. The main reason for this is in it too seek that, through the accumulation of blocked air or condensate water, one or the other the other radiator receives less steam, or that individual parts of the plates receive less get hot. In the case of drying cabinets with liquid heating medium, this is the same Particularly difficult to fill, because air sacs arise here, which act and isolate adversely affect warming; also unintentional deviation from the horizontal The location of the radiator is slightly detrimental.
Vor Allem ist man während des Betriebes, beim Trocknen, nicht in der Lage, etwaige Ungleichmäfsigkeiten zu beseitigen. Solche sind aber nicht nur dadurch schädlich, dafs sie die Güte des Erzeugnisses beeinträchtigen und die Dauer des Trockenvorganges verlängern, sondern sie können auch Gefahren mit sich bringen, z. B. beim Trocknen von Pulver oder anderen Sprengstoffen, indem einzelne Theile zu heifs werden, wenn andere noch nicht warm genug geworden sind.Above all, during operation, when drying, you are unable to remove any Eliminate irregularities. But such are not only harmful because they are the Impair the quality of the product and extend the duration of the drying process, rather they can also involve dangers, e.g. B. in the drying of powder or other explosives, by adding individual parts get too hot when others are not warm enough.
Die geschilderten Nachtheile lassen sich dadurch beseitigen, dafs man vor Ingangsetzen des Trockners oder auch während des Betriebes den Inhalt der Heizkörper absaugt; wird darauf das Heizmittel eingelassen, so füllt es die luftleeren oder nach Bedarf luftverdünnten Räume gleichzeitig aus.The disadvantages described can be eliminated by starting the process the dryer or during operation sucks the contents of the radiator; If the heating medium is then let in, it fills the evacuated or, if necessary, air-diluted Clear out at the same time.
Man hat Aehnliches schon bei Heizanlagen anderer Art vorgesehen, doch brauchte man dabei besondere Einrichtungen zum Absaugen bezw. zur Erzeugung der Luftleere. Das Wesentliche und Neue der vorliegenden Erfindung besteht nur darin, bei der Heizung von Vakuuintrocknern die zur Schaffung des Vakuums im eigentlichen Trockenraume, in dem das Gut liegt, ohnehin vorhandene Einrichtung zur Entlüftung der Heizkörper zeitweise mit zu verwenden, indem sie mit der Heizmittel- oder Condenswasserableitung in Verbindung gebracht wird. Unter Umständen ist es sogar vortheilhaft, das Absaugen durch den Vakuumtrockenraum selbst hindurch geschehen zu lassen, nämlich in denjenigen Fällen, wo es angezeigt ist, vor dem vollständigen Trocknen des Guts ein Anfeuchten zugleich mit einer Erwärmung durch die unmittelbare Berührung mit den heifsen Dämpfen vorzunehmen, also etwa um die Bildung einer harten Oberflächenschicht zu verhindern, welche das gleichmäfsige Trocknen des Gutes stört.Similar things have already been planned for other types of heating systems, but they were needed special facilities for suction respectively. to create the air void. That The only essential and novelty of the present invention is the heating of vacuum dryers that create the vacuum in the actual drying room, in where the goods are located, the existing facility for venting the radiators from time to time to be used by bringing it into connection with the heating medium or condensate water drainage. In certain circumstances it is even advantageous for the suction to take place through the vacuum drying room itself to leave, namely in those cases where it is indicated, before the complete Drying of the goods, a moistening at the same time with a warming by the immediate To make contact with the hot vapors, for example to prevent the formation of a hard surface layer, which disturbs the uniform drying of the goods.
Auf der beiliegenden Zeichnung ist die letzterwähnte Einrichtung beispielsweise schematisch vorgeführt.In the accompanying drawing, the last-mentioned device is, for example, a schematic demonstrated.
Es ist α der Vakuumbehälter, b die Zuleitung, c die Ableitung des Heizmittels. Die Ableitung c ist mit einem Umstellhahn d versehen, von dem aus das Heizmittel entweder in die Condensrohrleitung e oder durch das y in den Behälter α geht. Der AnschlufsIt is α the vacuum container, b the supply line, c the discharge line of the heating medium. The discharge line c is provided with a reversing valve d , from which the heating medium either goes into the condenser pipe e or through the y into the container α . The connection
an die Leitung zur Luftpumpe befindet sich bei dem Stutzen g. to the line to the air pump is at the connector g.
Das Auspumpen geschieht in erster Linie vor dem Beschicken bezw. Schliefsen des Trockners, dann aber auch je nach Bedarf während des Trocknens. . Der Wärter bedient nach seinen Erfahrungen oder Beobachtungen die betreffenden Hähne der Rohrleitung, welche dem Beheizen und Absaugen dient. Das Luftleerpumpen der Heizkörper erfordert nur wenige Secunden. Es kann auch eine Einrichtung getroffen werden, welche selbstthätig die Umschaltung der Hähne in gewissen Zeiträumen besorgt.The pumping takes place in the first place BEZW before loading. Closing the Dryer, but then also during drying as required. . The guard serves according to his experience or observations, which taps of the pipeline are concerned, which is used for heating and suction. Evacuating the radiators only requires a few seconds. A device can also be made which automatically the switchover of the taps in certain periods of time.
