Description

Die Erfindung betrifft eine Vorrichtung zur Herstellung einer Mischung aus verschiedenen Stoffen und ist insbesondere für Stoffe geeignet, deren Bestandteile leicht aneinanderhaften und die sich daher nur schwer miteinander vermischen.The invention relates to an apparatus for producing a mixture of different Fabrics and is particularly suitable for fabrics whose components easily adhere to one another and which are therefore difficult to mix with one another.

Es hat sich gezeigt, daß ein befriedigendes Mischen nur möglich ist, wenn immer nur eine bestimmte Menge gemischt wird, das Mischen also absatzweise erfolgt. Bei ununterbrochenem Aufgeben der zu mischenden Stoffe kann man nämlich niemals dafür einstehen, daß' die beabsichtigte Mischung wirklich vollständig durchgeführt wird und nicht an einzelnen Stellen des Gemisches andersartige Mischungsverhältnisse auftreten.It has been shown that satisfactory mixing is only possible if only ever a certain amount is mixed, i.e. the mixing takes place in batches. With uninterrupted If you give up the substances to be mixed, you can never guarantee that the intended mixture really is is carried out completely and not different at individual points in the mixture Mixing ratios occur.

Bei den bekannten Mischvorrichtungen fließt im allgemeinein das zu mischende Gut dem Mischraum in ununterbrochenem Strom zu, weil die vorgeschaltete Bearbeitungs- oder Fördereinrichtung ununterbrochen arbeitet.In the known mixing devices, the material to be mixed generally flows into it the mixing room in uninterrupted flow because the upstream processing or Conveyor works continuously.

Um diesen ununterbrochenen Zufluß selbsttätig in einen absatz weisen zu verwandeln, wird die Vorrichtung nach der Erfindung so ausgebildet, daß die aufgegebenen Stoffe in bestimmten Mengen angesammelt werden.In order to automatically transform this uninterrupted flow into a sales mode, the device according to the invention is designed so that the abandoned substances in certain amounts can be accumulated.

!Dabei werden in bekannter Weise sowohl bewegliche Mischkörper als auch mit dem Mischbehälter fest verbundene Mischmittel angewendet, wodurch die Mischkörper eine vielfach gebrochene Bahn während des Mischens zurücklegen, wobei sie auch auf diejenigen Stellen der Bahn des Mischgutes einwirken, welche der Wirkung der feststehenden Mischmittel mehr oder weniger entzogen bleiben, also auf tote Ecken und ähnliche Stellen.! Both movable mixing bodies and with the Mixing container firmly connected mixing means applied, whereby the mixing body a multiple cover broken web during mixing, whereby they also act on those parts of the web of the mixed material, which of the fixed mixing means remain more or less withdrawn, so on dead corners and similar places.

Nach erfolgter Mischung wird in an sich bekannter Weise eine Abscheidung der Mischkörper vorgesehen, um das gemischte Gut allein der Stelle der Weiterverwendung zuführen zu können.After mixing has taken place, the mixing bodies are deposited in a manner known per se provided in order to send the mixed goods to the point of further use alone to be able to.

Auf der Zeichnung ist diese Vorrichtung dargestellt, und zwar zeigtThis device is shown in the drawing, namely shows

Die Mischvorrichtung besteht aus der drehbaren Mischtrommel 1, die beim Ausführungsbeispiel zwei nebeneinanderliegende Räume, den Vormischraum 2 und den Austragraum 3, enthält. Beide Räume 2, 3 sind konzentrisch von den Mischkammern 4, 5 umgeben. Die zu mischenden Stoffe werden durch das Rohr 6 dem Vormischraum 2 zugeführt, in dem sie mit den Mischkörpern 7 zusammentreffen und zu einem Mischsatz angesammelt werden. Der den Vormischraum umgebende Mantel Γ ist mit einem sich über die ganze Breite des Raumes erstreckenden Austragspalt 8 versehen, durch den nach einmaliger Umdrehung der Trommel 1 der im Vormischraum 2 gebildete Mischsatz in die Mischkammer 4 gelangt. In dieser Kammer sind Mischschaufein 9 angeordnet, die, wechselseitig versetzt, die ganze Breite der Mischkammer überdecken und sich über die ganze Höhe der Misch-The mixing device consists of the rotatable mixing drum 1 which, in the exemplary embodiment, contains two adjacent spaces, the premixing space 2 and the discharge space 3. Both rooms 2, 3 are concentrically surrounded by the mixing chambers 4, 5. The substances to be mixed are fed through the pipe 6 to the premixing space 2, in which they meet with the mixing bodies 7 and are collected to form a mixed set. The jacket Γ surrounding the premixing space is provided with a discharge gap 8 extending over the entire width of the space, through which the mixing set formed in the premixing space 2 passes into the mixing chamber 4 after the drum 1 has rotated once. Mixing blades 9 are arranged in this chamber, which, alternately offset, cover the entire width of the mixing chamber and extend over the entire height of the mixing chamber.

Claims

extend chamber. The mixing blades 9 are mutually variable in their position to to be able to adapt their position to the flowability of the goods. An in the mixing room

5 arranged inclined guide plate 10 (Fig. 3) guides the mix together with the friction bodies through the Opening 11 in the partition 12 in the Mixing space 5. Adjustable mixing blades 13 are also arranged in this space in the same way as the mixing blades 9 of the chamber 4 the entire width of the Cover the mixing room and extend over the entire height of the room, so that by the shovels the mixing rate is raised again and again as a whole and therefore all of its constituents are intimately mixed with one another. The mixing room limiting wall of the drum 1 is with a spread across the width of the room extending discharge gap 14, to which the material is fed through a guide plate 15. The mixing set passes from the mixing chamber 5 through to the discharge gap 14 subsequent channel 16 in the discharge space arranged sieve drum 17. The material to be mixed falls through the sieve shell into the discharge space 3, from which it is continuously discharged by the screw 18. In the The digestion bodies remaining in the sieve drum 17 pass through the opening 19 into the centrally mounted return pipe 20 which opens into the premixing space 2. That the other end of the tube and the sieve drum 17 are after the discharge 21 of the mixing device completed so that the body 7 not from the sieve drum 17 and the pipe 20 in the discharge 21 'can'. In the pipe 20 is a screw conveyor 22, which conveys the body 7 into the premixing space 2. At the end of the task can the drum can be hermetically sealed with a cover 23.

i. Device for the production of a mixture of different substances in uninterrupted operations, characterized in that of the uninterrupted abandoned substances accumulated a certain amount and added to their movable mixing body, whereupon this amount, which has been collected and mixed with mixing bodies, is placed in a rotating drum or a similar mixing container is mixed with the assistance of mixing means firmly connected to the drum or chamber, after which the Separation of the mixed body and the discharge of the mixture takes place, so that the latter, appropriately in full or approximately uninterrupted currents, can be derived.

2.
