Description

KAISERLICHESIMPERIAL

PATENTAMT.PATENT OFFICE.

Die in Fig. 1 und 2 gezeichnete Mischmaschine besteht aus einem grofsen Misch-■ räume A, welcher durch verticale Querwände a und eine Längswand b in eine gröfsere Anzahl Theile getheilt und nach unten durch Wände c trichterartig eingezogen ist.The mixing machine shown in Figs. 1 and 2 consists of a large mixing room A, which is divided into a larger number of parts by vertical transverse walls a and a longitudinal wall b and drawn in like a funnel downwards by walls c .

Ueber der Zwischenwand b ist ein Kasten d Above the partition b is a box d

mit diagonal aufgeschlitztem Boden α, Fig. 3, ^längs des Mischraumes angebracht, in welchem über Rollen e ein endloses Band β mit daran befestigten Querhölzern f läuft.with diagonally slit bottom α, Fig. 3, ^ attached along the mixing space, in which an endless belt β with attached crossbars f runs over rollers e.

Wird durch den Einfüllrumpf g mittelst der Steigrohre h bezw. durch den Einfüllrumpf i die zu mischende Substanz auf das Band β gebracht, so wird diese durch die Hölzer f in Schichten gleich der Höhe der Hölzer eingezogen und auf dem Boden weiter befördert.Is through the filling hull g by means of the riser pipes h respectively. the substance to be mixed is brought onto the belt β through the filling hull i , so it is drawn in through the wood f in layers equal to the height of the wood and transported on the floor.

Durch den diagonalen Schlitz α fällt nun das Mischgut während des Transports aus dem Kasten d, geführt durch an. diesem Kästen angebrachte Leitbrettchen k und die schrägen Wände Z rechts und links in die Abtheilungen des Mischraumes A, The mix now falls through the diagonal slot α during transport out of the box d, guided by. Guide boards k attached to this box and the sloping walls Z to the right and left into the compartments of the mixing room A,

Das ganze zu mischende Quantum, durch einander oder in beliebiger Reihenfolge in .den Kasten A eingebracht, lagert auch in derselben Reihenfolge über einander, und es sind in allen Abtheilungen des Mischraumes die genau gleichen Verhältnisse der einzelnen Mengen vorhanden, also das Mischungsverhältnifs dasselbe.The whole quantity to be mixed, placed in box A one by one or in any order, is also superimposed in the same order, and exactly the same proportions of the individual quantities are present in all sections of the mixing room, i.e. the proportions of the mixture are the same.

Diese von einander getrennten Abtheilungen können nun auch unabhängig von. einander gemischt werden.These divisions, separated from one another, can now also be independent of. each other be mixed.

Man hat es auf diese Weise mit kleinen Massen zu thun, die sich bequem bewältigen lassen, während in grofsen Massen Mehl, auf welches hierbei namentlich,Rücksicht genommen ist, in seinem Verhalten unberechenbar ist, weil seine physischen Eigenschaften abhängig sind von der Güte des Mehles, der Zeit, während welcher es gelagert und den kleinen Bodenerschütterungen infolge des Betriebes, so dafs es sich bestimmten Operationen nicht fügt.In this way one has to deal with small masses which are easy to manage leave, while in large quantities flour, which is particularly important here is, is unpredictable in its behavior because its physical properties are dependent of the goodness of the flour, the time during which it was stored, and the small shaking of the ground as a result of the operation, so that it does not conform to certain operations.

Unter jeder Längsreihe von Abtheilungen liegt eine gerippte Walze m, unter diesen je eine Schnecke n, beide durch die Riemscheiben 0 und o1 und die Zahnräder ρ und q in Bewegung gesetzt. Oeffnet man nun mittelst Schiebers r oder durch eine andere Vorrichtung eine der Abtheilungen des Kastens A, so fördert die Walze m den Inhalt dieser Abtheilung in die Schnecke η und diese mittelst Fallrohres s und Steigrohres h wieder auf das Band β.Under each longitudinal row of compartments lies a ribbed roller m, under each of which there is a worm n, both set in motion by the pulleys 0 and o 1 and the gears ρ and q. If one of the compartments of the box A is opened by means of the slide r or some other device, the roller m conveys the contents of this compartment into the screw η and this again by means of the downpipe s and the riser pipe h onto the belt β.

Durch Umstellung der Wände Z, wie Fig. 4 dies zeigt, wird nun ein Trog gebildet, in welchen mittelst des Bandes β durch den schrägen Schlitz der Inhalt einer ganzen Abtheilung der ganzen Länge des Kastens entlang fällt.By moving the walls Z, as shown in FIG. 4, a trough is now formed in which by means of the band β through the oblique slit the contents of a whole division of the falls along the length of the box.

Es sind in diesem Troge die einzelnen Sorten wiederum in sehr flachen Schichten über einander gelagert.In this trough, the individual varieties are again in very flat layers on top of one another stored.

Wird . der Trog geöffnet, wie Fig. 5 dies zeigt, so fällt sein Inhalt in den Schneckenkasten t mit der Schnecke u. Der Kasten t ist grofs genug, um den Inhalt einer Abtheilung so zu fassen, dafs die Schnecke u eben überdeckt wird.Will . If the trough is opened, as shown in Fig. 5, its contents fall into the snail box t with the snail u. The box t is large enough to hold the contents of a compartment in such a way that the snail u is just covered.

Die Schnecke mit sehr enger Steigung, deren Schaufeln aus- einzelnen von einander etwasThe snail with a very narrow pitch, the blades of which are somewhat separated from each other

abstehenden Segmenten gebildet sind, mischt und bewegt das Gut in die darunter befindliche zweite Schnecke v; diese vollendet die Mischung und fördert es nach dem Auslauf w hin. protruding segments are formed, mixes and moves the material in the underlying second screw v; this completes the mixture and conveys it to the outlet w .

Der geöffnete Trog schliefst sich nach der Entleerung selbsttätig, eine zweite Abtheilung des Mischraumes A wird geöffnet, während nun der Inhalt der ersten Abtheilung am Auslauf n> in Säcken abgefangen wird u. s. f.The opened trough closes automatically after emptying, a second section of the mixing space A is opened, while the contents of the first section are now caught in sacks at the outlet n> , and so on
