Description

Vorrichtung zum Vorbehandeln von Zementrohgut Die Erfindung betrifft eine Vorrichtung zum Vorbehandeln von Zementrohgut mittels der. Abgase des Brennofens, und das Neue besteht darin, daß sie aus zwei in geringen Abstand voneinander angeordneten gasdurchlässigen Wänden besteht, die von oben in einen Sammelraum für das Gut hineinragen und zwischen sich einen Schacht bilden, durch den das Gut absinkt, so daß die quer durch die Wände geführten Gase zum Teil auch durch das sich frei abböschende Gut hindurchströmen.Device for pretreating raw cement material. The invention relates to a device for pretreating cement raw material by means of. Furnace exhaust gases, and what is new is that they are made up of two closely spaced apart gas-permeable walls that protrude from above into a collecting space for the goods and between them form a shaft through which the material sinks, so that the cross Gases guided through the walls partly also through the freely sloping material flow through.

Zweckmäßig werden die gasdurchlässigen Wände ringförmig ausgebildet und gleichachsig ineinander angeordnet.The gas-permeable walls are expediently designed to be annular and coaxially arranged one inside the other.

Gegenüber den bekannten Vorrichtungen zeichnet sich die Vorrichtung gemäß der Erfindung durch ihre ,einfache und billige Bauart aus.The device is distinguished from the known devices according to the invention by their, simple and cheap design.

Die Zeichnung stellt im senkrechten Schnitt ein Ausführungsbeispiel der Erfindung ' dar. Die beiden gleichachsig ineinander angeordneten ringförmigen Wände 14 und 15 sind mit Öffnungen :oder Schlitzen 16 versehen, die in der Durchgangsrichtung des Gutes geneigt verlaufen, um ein Hinausfallen des Gutes durch die Ringwände zu verhindern. Die Abgase streichen durch die Öffnungen 16 der Ringe 14 und 15 und durch das im Ringraum befindliche Gut hindurch, aber auch unterhalb der Ringe durch das sich abböschende Gut, Dies hat den Vorteil, daß auch durch das getrocknete Gut nach dem Verlassen des ringförmigen Schachtes noch Gas hindurchströmt, wodurch bei angestrengtem Betrieb ohne weiteres eine Überlastung der Einrichtung ermöglicht wird.The drawing shows an embodiment of the invention in vertical section. The two coaxially arranged annular walls 14 and 15 are provided with openings: or slots 16 which run inclined in the direction of passage of the goods in order to prevent the goods from falling out through the annular walls impede. The exhaust gases pass it through the openings 16 of the rings 14 and 1 5 and through the left in the annular space Good therethrough, but also below the rings through which abböschende well, this has the advantage that the annular shaft by the dried after leaving gas still flows through it, whereby an overload of the device is easily made possible during strenuous operation.

PATENTANSPRÜCHR i. Vorrichtung zum Vorbehandeln von Zeinentrohgut mittels der Abgase des Brennofens, dadurch gekennzeichnet, daß sie aus zwei in geringem Abstand voneinander angeordneten gasdurchlässigen Wänden (i4 und 15) besteht, die von oben in .einem Sammelraum (12) für das Gut hineinragen und zwischen sich einen Schacht bilden, durch den das Gut absinkt, so daß die quer durch die Wände geführten Gase zum Teil auch durch das sich frei abböschende Gut hindurchströmen. Vorrichtung nach Anspruch i, dadurch gekennzeichnet, daß der Schacht in an sich bekannter Weise ringförmig ausgebildet ist, also aus zwei gleichachsig ineinander angeordneten gasdurchlässigen Wänden (14 und 15) besteht.PATENT CLAIM i. Apparatus for pretreating Zeinentrohgut by means of the exhaust gases of the kiln, characterized in that it consists of two spaced a small distance gas-permeable walls (i4 and 1 5) which project from above into .einem collecting chamber (12) for the material, and between them Form a shaft through which the material sinks, so that the gases led across the walls partly also flow through the freely sloping material. Device according to Claim i, characterized in that the shaft is designed in a manner known per se in the form of a ring, that is to say consists of two gas-permeable walls (14 and 15) arranged coaxially one inside the other.
