Description

Schwingsieb mit beheiztem Siebboden Bei :der Absiebung von feuchtem Gut, insbesondere bei -der Feinabsiebun g, tritt häufig der Umstand auf, daß sich der aus gelochtem Blech oder Siebgewebe bestehende Siebboden zusetzt und eine weitere Absiebung unmöglich macht. Um diesen Nachteil zu beheben, ist bereits vorgeschlagen worden, das Siebgewebe selbst als elektrischen Heizkörper auszubilden und an ihn eine Spannung anzulegen. Diese Arbeitsweise ist aber sehr unwirtschaftlich. Es ist andererseits bekannt, unterhalb eines hin und her bewegten Siebes Gasbrenner anzuordnen und die Verbrennungsgase oder ein geeignetes Gas-Luft-Gemisch in den Raum unterhalb des Siebgewebes einzuleiten, um auf -diese Weise eine Beheizung der S.ielydrähte durchzuführen, wodurch :das am Siebgewebe haftende Gut getrocknet und zum Abfallen gebracht wird. Es ist ferner belcannt, Rohbraunkohle im Naßdienst auf einem Rost abzusieben, dessen Roststäbe hohl ausgebildet sind und zwecks Beheizung von Dampf durchströmt werden. Diese bekannte Bauart dient zum Trocknendes über den Rost hinweggleitendenGutes.Vibrating sieve with heated sieve bottom When: sieving damp Good, especially in the case of fine sieving, the circumstance often occurs that the perforated sheet metal or sieve mesh clogs up the sieve bottom and another Makes screening impossible. In order to remedy this disadvantage, it has already been proposed been to train the screen mesh itself as an electric heater and to him to apply a voltage. However, this way of working is very uneconomical. It is on the other hand known to arrange gas burners below a screen moving back and forth and the combustion gases or a suitable gas-air mixture in the space below of the sieve mesh in order to heat the S.iely wires in this way to carry out, whereby: the material adhering to the sieve fabric is dried and ready to fall off is brought. It is also scanned, raw lignite in wet service on a grate sieve, the grate bars are hollow and for the purpose of heating steam are flowed through. This known design serves to dry the goods that slide over the grate.

Die Erfindung geht von einem Schwingsieb aus, bei dem lediglich der Siebbelag, insbesondere das Siebgewebe, angewärmt werden soll, und besteht darin, daß die Trag- und Unterstützungskonstruktion für den Siebbelag aus einem in sich geschlossenen Rohrsystem besteht, durch das heißes Gas oder Dampf hindurchgeleitet wird. Durch die Berührung des Siebbelages mit -der Tragkonstruktion erfolgt eine Wärmeübertragung, die ausreicht, um das anhaftende Gut zu trocknen. Die Heizung des Rohrsystems mit Dampf ist besonders zweckmäßig und wirtschaftlich, da diesem in den Aufbereitungsanlagen für Kohle und Erz, in denen vorzugsweise derartige Absiebungen von feuchtem Gut vorgenommen werden, ständig und wohlfeil zur Verfügung steht. Selbstverständlich können auch andere Verbrennungs- oder Abgase oder auch erhitzte Luft zur Beheizung des Siebes benutzt werden.- Die Heizgase werden zweckmäßgerweise mit Hilfe einer nachgiebigem Rohr- oder Schlauchverbindung der Tragkonstruktion zugeführt.The invention is based on a vibrating screen in which only the The screen lining, in particular the screen mesh, is to be warmed up, and consists of that the support and support structure for the screen lining from one in itself closed pipe system through which hot gas or steam is passed will. When the screen lining comes into contact with the supporting structure, a Heat transfer that is sufficient to dry the adhering material. The heating system the pipe system with steam is particularly useful and economical, as this in the processing plants for coal and ore, in which such screening is preferred be made by moist material, is constantly and cheaply available. Of course can also use other combustion or exhaust gases or even heated air for heating of the sieve used - The heating gases are expediently with the help of a flexible pipe or hose connection of the supporting structure fed.
