Description

Vorrichtung zur Erzeugung von wasser- und eisenfreiem Schlackensand oder schaum Mit vorliegender Einrichtung wird zunächst in bekannter Weise aus geschmolzenen heißflüssigen Stoffen, wie Hochofenschlacke u. dgl., gekörntes Material in der Körnungs- und Verteilungsrinne a im fließenden Warmwasserstrom erzeugt und in die rotierende Trockentrommel b weitergeleitet. Erfindungsgemäß werden in deren Vorderteilc durch geeignete Einbauten und Siebe unverbrauchte hörnungsflüssigkeit und beigemengte schwere Teile, wie Eisenkörnchen u. dgl., durch Schleuderwirkung abgeschieden, worauf in deren Mittelteild die im umgewälzten Material noch verbliebene Restflüssigkeit in belçalmter Weise durch die noch darin entbahene Wärme verdampft wird.Device for the production of anhydrous and iron-free slag sand or foam With the present device is first made in a known manner from melted hot liquid substances, such as blast furnace slag and the like, granular material in the granular and distribution channel a is generated in the flowing hot water stream and into the rotating one Forwarded drying drum b. According to the invention are in the front part by suitable internals and sieves unused hearing fluid and admixed heavy parts, such as iron granules and the like, separated by centrifugal action, whereupon in the middle part the residual liquid still remaining in the circulated material is evaporated in a belçalmter way by the heat still released in it.

Nach der Überführung des entstandenen Schlackensandes oder -schaumes aus der geradlinigen Bewegung in der Rinnea in die rotierende Bewegung der Trommeln werden die etwa entstandenen Klumpen durch die Einbauten im Trommelteil c zerrissen und zerschlagen und die schweren Teile, wie Eisenkörnchen u. dgl., separiert und zentrifugal abgeschleudert, die durch ihre große Härte in den Transportelemerten und sonstigen Einrichtungsgegenständen unnötigen Verschleiß verursachen. After transferring the resulting slag sand or foam from the rectilinear movement in the rinnea into the rotating movement of the drums the lumps that may have arisen are torn up by the internals in the drum part c and crushed and the heavy parts such as iron granules and the like, separated and centrifugally thrown off, which due to their great hardness in the transport elements and other furnishings cause unnecessary wear and tear.

Die schnelle zentrifugale Trennung der Granulationsflüs sigkeit verhindert die Sättigung des Schlackensandes mit Flüssigkeit und fördert die Verdampfung der noch verbliebenen Flüssigkeitsspuren durch die Eigenwärme des Sandes, so daß es möglich ist, denselben ganz trocken zu erzeugen und ihm alle für die Nachverarbeitung wertvollen Eigenschaften zu erhalten. The rapid centrifugal separation of the granulation liquid is prevented the saturation of the slag sand with liquid and promotes the evaporation of the still remaining traces of liquid due to the inherent heat of the sand, so that it it is possible to produce the same completely dry and all of it for post-processing to preserve valuable properties.

Die abgeschiedenen schweren Teile werden durch die rückwärts abgezweigte, schräg angeordnete Schurre, welche im schrägen Boden einen Rost zur Abtropfung des beigemengten Wassers besitzt, abgeleitet. The separated heavy parts are branched off backwards, diagonally arranged chute, which has a grate in the inclined floor for draining the added water, derived.

Der gewonnene Sand und die durch den Rost der Trockentrommel etwa durch. schleuderten Sandteilchen werden vom Schüttler f aufgefangen und zum Silo g über dem Transporteure befördert, der ihn später zur Venvendungsstelie bringt. The sand recovered and the grate of the drying drum, for example by. Thrown sand particles are caught by the shaker f and sent to the silo g transported over the carrier who later brings it to the point of use.

Die I9örnungsflüssigkeit fließt vom Sammelbehälter Ii der Körnungsrinne a zu und wird nach Bedarf reguliert. The granulation liquid flows from the collecting container Ii of the granulation channel a and is regulated as required.
