Description

Offener Wärmeaustauscher Die Erfindung bezieht sich auf offene Wärmeaustauscher, z. B. zum Kühlen von Gut vorzugsweise staubförmiger Beschaffenheit mittels Kühlgase, und verfolgt das Ziel, ein Auflockern des Gutes unabhängig vz)n der Strömung des Kühlgutes zu bewirken, zu welchem Zweck ein Hilfsgasstrom der Gutsschicht von unten her zugeleitet wird. Bei den bekannten Vorrichtungen sind hierfür Schlitze oder ähnliche Durchlässe in der Gutsauflagefläche vorgesehen; durch sie fällt leicht Gut hindurch, und zudem wird die Auflockerung dabei ungleichmäßig oder ganz verhindert, indem sich über den Durchlässen Kanäle im Gut bilden, durch die das Hilfsgas hindurchpfeift, während andere Teile des Gutes ungelockert bleiben.Open heat exchanger The invention relates to open heat exchangers, z. B. for cooling goods, preferably of a dusty nature, by means of cooling gases, and pursues the goal of loosening up the goods independently vz) n the flow of the To effect cooling goods, for which purpose an auxiliary gas flow of the Gutsschicht from below is forwarded. In the known devices for this purpose slots or Similar passages are provided in the product support surface; through it is easy Well through, and also the loosening is unevenly or completely prevented, by forming channels in the material through the passages through which the auxiliary gas whistles, while other parts of the property remain unscrewed.

Gemäß der Erfindung ist das Kühlgut auf einer porig ausgebildeten Tragfläche mit vielen kleinen Öffnungen gelagert, durch die ein Hilfsgasstrom von unten her geleitet wird,. Hierdurch wird eine gleichmäßige Verteilung des Hilfsgases gesichert, ein Hindurchpfeifen an einzelnen Stellen und ein Durchfall von Gut aber unbedingt verhütet.According to the invention, the goods to be cooled are formed on a porous Supported wing with many small openings through which an auxiliary gas flow of is directed below. This ensures a uniform distribution of the auxiliary gas secured, a whistling through in individual places and a diarrhea from Gut but absolutely prevented.

Die Zeichnung stellt schematisch ein Ausführungsbeispiel der Erfindung dar und zeigt eine Kühlvorrichtung im Schnitt.The drawing shows schematically an embodiment of the invention and shows a cooling device in section.

In dem ortsfesten Gehäuse i ist die Kammer 2 schwingbar gelagert und kann zur Unterstützung der auflockernden Wirkung des Hilfsgasstromes mittels des Antriebs 3 in auf und ab gehende Schwingungen versetzt werden. In ihr ist die aus einer porigen Platte 4 gebildete Tragfläche vorgesehen, auf der sich das Gut befindet, das mittels eines durch die Leitung 5 zugeführten, durch die Leitung 6 abziehenden Kühlmittels, vorzugsweise Luft oder Gas, behandelt wird. Das Gut wird durch den Zulauf 7 über die Zuteilschnecke S aufgegeben und mittels des im Sinne des Pfeiles x umlaufenden, mit Krählern g besetzten, endlosen Bandes io auf der porigen Tragfläche .l ausgebreitet und über sie gefördert, um schließlich durch den Auslauf i i die Kammer a zu verlassen. Unterhalb der porigen Tragfläche ¢ tritt durch die Leitung 12 ein Hilfsgasstrom ein, der durch die Poren der Platte 4. in die Gutsschicht gelangt und durch die Ableitung 6 mit abzieht.In the stationary housing i, the chamber 2 is pivotably mounted and can to support the loosening effect of the auxiliary gas flow by means of Drive 3 are set in oscillations going up and down. It is over in her a porous plate 4 formed support surface is provided on which the material is located, by means of a supplied through line 5, withdrawn through line 6 Coolant, preferably air or gas, is treated. The good is made by the Inlet 7 abandoned via the metering screw S and by means of the in the direction of the arrow x encircling endless band io occupied with crows g on the porous wing .l spread out and conveyed over them to finally through the spout i i the Leave chamber a. Below the porous airfoil ¢ comes through the pipe 12 a flow of auxiliary gas, which passes through the pores of the plate 4 in the material layer and subtracts through the derivation 6.

Das endlose Band i o läuft über die Rollen i 3 und wird durch nicht dargestellte Mittel angetrieben.The endless belt i o runs over the rollers i 3 and is not through means shown driven.

Mit Rücksicht auf die Schwingungen der Kammer 2 sind alle Anschlüsse zwischen ihr und dem ortsfesten Gehäuse i nachgiebig ausgebildet.With regard to the vibrations of the chamber 2, all connections are between it and the stationary housing i formed resilient.
