Description

:Die Erfindung. betrifft eine Drehtrommel zum Brennen vön;Ze:ment ui d fiir* ähnl@ich@e Zwecke riiif an der Rohrwand angeordneten hohlen und ' vorn einem INthlmittel durchflossenen-Einbauten, wie. Schaufeln u. dgl. Bei derartigen Anlagen hat sich gezeigt, daß. die naturgemäß am stärksten von der .Ofenhitze ä,nkegrifferien Innenwände der Hub-" schaufeiuu. ä: Einbauten bisher nicht wirksam vor Zeirsfiörungesn, geschützt werden: komlten, weil.- die Kühlung dieser Stellen durch, das ein.geführte'Küh1=- mittel nur =vollkommen, war. Dieser M.ißstand wird gemäß der Erfindung, da- durch behoben, daß das Kühlmi:tfiel dien innersteh nach: der Trommelachse hin gelegenen: Enden der Einbauten durch in der Trommelnii.tte ab@geordmete Rohrleitungen unmittelbar zugeführt wird. Die Zeichnung stellt schematisch ein Ausfüh-_ rungsbesspiel der Erfinidung @:diar und zeigt einen . Drehrohrofen im Querschnitt. An der Ofeawand i sind@ Hubschaufeln 2 an- gebracht, diie bei Drehung des Ofens im Sinne des Pfeiles den, Ofeninhalt von der Sohle .emporheben und dann frei niederfallen lassen" wodurch - einte gründliche Durchruttelung des. zu behandelnden Gutes herbeigeführt und dieses den Heizgasen wirksam ausgesetzt wird. Vom Stirnende des Ofenirollres führt eine Luft- leitung 3 hinein, von welcher Ableitungen. 4 stern- förrnig nach dien inneren Enden der" Schaufeln 2 gehen. Diese Schaufeln 2: sind! in an sich bekannter Weise hohl ausgebildet,urnd; werden von der durch die' Leitungen d, ihnen zugeführten Kühlluft oder einem anderen, Kühlmittel durchströmt, wobei das Kühlmittel aus- an der Außenseite des Drehrohres i befindlichen Miindüngen-5 austritt. Da das frische Kühlmittel in. die Schaufeln a an: ihrem inneren Enden eintritt, werden, diese am stärksten, gekühlt. so daß sie trotz ihrer freien Lage und starken Umspülung von den Heizgasen wirksam vor Zerstörungen, geschützt werden. :The invention. concerns a rotary drum for Burning of; Ze: ment and for similar purposes riiif on the pipe wall arranged hollow and 'in front internals through which a coolant flows, such as. Shovels and the like. In such systems shown that. naturally the strongest of the .Oven heat outside the inner walls of the lift " schaufeiuu. ä: Built-in components have not yet been effective Zeirsfiörenesn, be protected: komlten, because.- the Cooling of these places through, the introduced 'Küh1 = - medium only = perfect, was. According to the invention, this deficiency is by remedying that the coolant was inside after: the drum axis towards: ends of the Built-in components through in der Trommelnii.tte ab @ geordmete Pipelines is fed directly. The drawing shows schematically an execution rungsbesspiel der Invention @: diar and shows one. Rotary kiln in cross section. @ Lifting shovels 2 are attached to the Ofeawand i brought, diie with rotation of the furnace in the sense of Arrow to lift the contents of the oven from the sole and then let fall down freely "whereby - united thorough shaking of the. to be treated Good brought about and this the heating gases effectively exposed. An air duct leads from the front end of the oven line 3 in, from which derivatives. 4 star angular towards the inner ends of the "blades 2 walk. These shovels 2: are! in itself known Wise hollow formed, and; are traversed by the cooling air supplied to them through the lines d or by some other coolant, the coolant emerging from small fertilizers 5 located on the outside of the rotary tube i. Since the fresh coolant enters the blades at their inner ends, these are cooled the most. so that they are effectively protected from destruction despite their free position and strong flushing of the heating gases.
