Description

KAISERLICHESIMPERIAL

PATENTAMT.PATENT OFFICE.

Die vorliegende Erfindung bezieht sich auf Mischmaschinen für pulverförmiges oder körniges Gut und ist dadurch gekennzeichnet, dafs die zum Fortbewegen des Materials Verwendung findenden Messer gleichzeitig zum Mischen desselben benutzt werden. Früher geschah die Mischung einfach dadurch, dafs die rotirenden Messer das Material im Sinne ihrer Drehungsrichtung umstürzten. Im Gegensatz dazu sind die vorliegenden Messer so eingerichtet, dafs sie sowohl in der eben genannten Weise wirken, als auch dadurch, dafs von ihnen das Gut vorwärts und wieder rückwärts bewegt wird, bevor ein endgültiger Vorschub desselben stattfindet. Das Mischgut macht also aufser der drehenden Bewegung auch eine solche in axialer Richtung zur Maschine, und zwar eine, welche dem eigentlichen Vorschub entgegengesetzt ist.The present invention relates to mixing machines for powder or granular Good and is characterized by the fact that it is used to move the material finding knife can be used at the same time to mix the same. That happened earlier Mixing simply by the fact that the rotating knives overturned the material in the direction of its direction of rotation. In contrast, are the present knives are set up so that they can be used both in the manner just mentioned act, as well as by the fact that they move the good forwards and backwards again before a final advance of the same takes place. So the mix makes a difference of the rotating movement also one in the axial direction to the machine, namely one, which is opposite to the actual feed.

Zu diesem Zwecke werden die Transportmesser, wie aus Fig. 3 der Zeichnung ersichtlich, nicht mit einer einfachen Transportflä'che α versehen, sondern prismatisch ausgebildet, so dafs eine weitere, zur Achse der Maschine geneigte Fläche b entsteht, welche beim Rotiren der Messerwelle das Bestreben hat, das Material gegen die durch α hervorgerufene Transportrichtung zurückzuschieben.For this purpose, as can be seen from Fig. 3 of the drawing, the transport knives are not provided with a simple transport surface α , but are designed in a prismatic manner, so that a further surface b is created, inclined to the axis of the machine, which when the cutter shaft rotates Has endeavored to push the material back against the direction of transport caused by α.

Sollen nur einflügelige Messer Verwendung finden, so mufs natürlich diejenige der beiden Flächen α und b, welche den endgültigen Vorschub bewerkstelligen soll, eine stärkere Neigung zur Achse der Maschine erhalten. Um einen noch besseren Effect zu erzielen, empfehlen sich die in der Zeichnung dargestellten zweiflügeligen Messer, bei denen die das Zurücktreiben des Materials gegen die Transportrichtung bewirkende Fläche b stärker gegen die Achse geneigt ist als Fläche a. In diesem Fall mufs natürlich dafür Sorge getragen werden, dafs trotzdem der Vorschub des Materials in beabsichtigter Richtung erfolgt, und zwar geschieht dies durch Anordnung des zweiten Flügels c, welcher eine mit der Fläche a correspondirende Neigungsfläche hat, so dafs sich die Flächen α und c behufs der Transportbewegung summiren und so den durch Fläche b erfolgten Rückschub wieder aufheben, nachdem derselbe vorher zur gehörigen Mischung des Gutes gedient hat.If only single-wing knives are to be used, that of the two surfaces α and b, which is intended to bring about the final feed, must of course have a greater inclination to the axis of the machine. In order to achieve an even better effect, we recommend the two-winged knives shown in the drawing, in which the surface b causing the material to be driven back against the transport direction is more inclined towards the axis than surface a. In this case care must of course be taken to ensure that the material is fed in the intended direction, namely by arranging the second wing c, which has an inclined surface corresponding to surface a , so that surfaces α and c add up for the purpose of the transport movement and thus cancel out the push back caused by surface b , after it has previously served to mix the goods appropriately.

Patent-Ansprüche:Patent Claims: ι. Keilförmiges Treibmesser an Mischmaschinen für pulverförmiges und körniges Gut, welches aufser der den Vorschub des Materials in der Richtung der Drehachse bewirkenden Fläche α noch eine Gegenfläche b besitzt, welche die entgegengesetzte Neigung zur Drehachse und daher das Bestreben hat, das Material rückläufig zu bewegen.ι. Wedge-shaped driving knife on mixing machines for powdery and granular material, which, in addition to the surface α causing the feed of the material in the direction of the axis of rotation, has a counter surface b which has the opposite inclination to the axis of rotation and therefore tends to move the material backwards. 2. Verwendung von Treibmessern c mit einseitiger Vorschubfläche in Verbindung mit den unter 1. geschützten Keilmessern, insbesondere für den Fall, dafs bei letzteren die Vorschubfläche α einen gröfseren Neigungswinkel, mit der Drehachse bildet als die Fläche b. 2. Use of drive knives c with a one-sided feed surface in connection with the wedge knives protected under 1., especially for the case that in the latter the feed surface α forms a larger angle of inclination with the axis of rotation than the surface b.
