Description
Die Erfindung betrifft eine Drehtrommel zum Brennen, Trocknen oder Kühlen von Massengut, wie Zement od. dgl., mit am Innenumfang ringförmig angeordneten Hubschaufeln und von diesen in radialem Abstand konzentrisch angeordnetem Verteilungsring, und das Neue besteht darin, daß der Verteilungsring außen durch zwei konische Flächen begrenzt ist. Zweckmäßig werden dabei die Verteiler an jede Hubschaufel angefügt und aus kegelseb,-mentartigen Teilen gefertigt, wobei diese vorteilhaft verschiedene Neigung haben und an oder nahe ihnen Ketten vorgesehen sind. Besonders günstig ist es, die kegeligen Verteilflächen mit Schlitzen, Öffnungen oder anderen Unterbrechungen zu versehen, und zweckmäßig werden in -angemessenem Abstand vom Verteilungsring beiderseits weitere konische Verteilungsringe angeordnet, deren konische Außenfläche die gleiche oder eine geringere Neigung zur Ofenachse besitzt als die ihr näher liegende Konusfläche des Verteilungsringes.The invention relates to a rotary drum for burning, drying or Cooling of bulk goods, such as cement or the like, with annularly arranged on the inner circumference Lifting blades and a distribution ring concentrically arranged at a radial distance from them, and what is new is that the distribution ring is externally provided by two conical surfaces is limited. The distributors are expediently attached to each lifting shovel and made of kegelseb, -ment-like parts, these advantageously different Have inclination and chains are provided on or near them. Is particularly cheap es, the conical distribution surfaces with slots, openings or other interruptions and appropriately spaced from the distribution ring further conical distribution rings arranged on both sides, their conical outer surface has the same or less inclination to the furnace axis than that closer to it lying conical surface of the distribution ring.
Die Zeichnung stellt schematisch ein Ausführungsbeispiel dar und zeigt in Abb. i einen Teilschnitt durch eine Drehtrommel, in Abb. 2 in größerem Maßstab eine Einzelheit an einem anderen Ausführungsbeispiel.The drawing schematically represents and shows an exemplary embodiment in Fig. i a partial section through a rotating drum, in Fig. 2 on a larger scale a detail of another embodiment.
In der Drehtrommel io (Abb. i) sind in einer ringförmigen Zone Hubschaufeln r i angebracht und in radialem Abstand davon gleichachsig mit ihr ein Verteilungsring r2, der nach außen durch zwei konische Flächen begrenzt ist, deren Abstände sich in Richtung zum Zentrum hin erweitern. Das von den Hubschaufeln i i angehobene Gut fällt aus diesen, wie die Pfeile andeuten, auf die konischen Flächen des Verteilungsringes und wird nachher nach beiden Seiten hin schleierartig abgeworfen.In the rotary drum io (Fig. I) there are lifting blades in an annular zone r i attached and a distribution ring equiaxed with it at a radial distance from it r2, which is limited to the outside by two conical surfaces, the distances between which expand towards the center. The goods lifted by the lifting shovels i i falls from these, as the arrows indicate, onto the conical surfaces of the distribution ring and is thrown off afterwards like a veil on both sides.
Bei dem in Abb.2 dargestellten Ausführungsbeispiel sind an den in der Drehtrommel 2o sitzen-, den Hubschaufeln 2i mehrere Verteiler 24 angefügt, welche kegelige Flächen 22 und 23 von verschiedener Neigung besitzen, in denen Öffnungen 25 vorgesehen sind. Kettenstücke 26 sitzen in den Verteilern 23, während andere Kettenstücke 27 unmittelbar an der Trommelwandung 2o aufgehängt sind. Dabei haben die axial weiter nach außen liegenden Verteilerflächen 22 eine geringere Neigung zur Ofenachse als die ihr näher liegenden Konnsflächen 23.In the embodiment shown in Fig the rotary drum 2o sit-, the lifting blades 2i several distributors 24 attached, which have conical surfaces 22 and 23 of different inclination in which openings 25 are provided. Chain pieces 26 sit in the manifolds 23, while others Chain pieces 27 are suspended directly from the drum wall 2o. Have along the distributor surfaces 22 located axially further outwards have a smaller inclination to the furnace axis than the contact surfaces 23 which are closer to it.
Mit . dieser Einrichtung wird eine besonders günstige Verteilung des angehobenen Gutes erzielt, indem es nicht nur in einzelnen schleierartigen Flächen niederfällt, sondern solche in so großer Zahl gebildet werden, daß eine Zone von erheblicher axialer Länge völlig von niederfallendem Gut erfüllt wird.With . this facility is a particularly favorable distribution of the raised good is achieved by not only using it in individual veil-like surfaces falls, but such are formed in so great numbers that a zone of considerable axial length is completely fulfilled by falling material.
