Description

Einrichtung zum Bemessen von Schüttgütern In Mischanlagen werden zum Bemessen von Schüttgütern drehzahlgeregelte Kammerschleusen verwendet. Diese hat man bisher über trichterförmige Ausläufe an die Vorratsbehälter angeschlossen. Hierbei ergab sich der wesentliche Nachteil, daß an den Schrägflächen der trichterförmigen Ausläufe Brücken bildende Stützkräfte vorhanden waren, die einen unregelmäßigen Materialfluß hervorriefen. Ferner ergab sich bei den bekannten Einrichtungen, daß die entleerten Kammern der Schleuse beim Umlauf Luft in den Füllraum des Gerätes schöpften. Das sich dadurch bildende Luftkissen verhinderte eine gleichmäßige und kontrollierbare Füllung der Meßkammern.Device for dimensioning bulk goods In mixing plants for For the dimensioning of bulk materials, speed-controlled chamber locks are used. This has previously connected to the storage container via funnel-shaped outlets. Here the main disadvantage was that on the inclined surfaces of the funnel-shaped Supporting forces that formed bridges and formed an irregular spout were present Caused material flow. Furthermore, it was found in the known facilities that the emptied chambers of the lock when air is circulated into the filling chamber of the device scooped up. The resulting air cushion prevented a uniform and controllable filling of the measuring chambers.

Gemäß der Erfindung werden die genannten Nachteile dadurch vermieden, daß in dem Vorratsbehälter unmittelbar über dem Rührwerk vor dem Bodenauslauf eine in der Höhe verstellbare Kulisse angeordnet ist, und die Kammerschleuse über einen Überströmkanal mit einer sich selbst reinigenden Ringkammer mit Füll- und Abschüttraum in Verbindung steht. According to the invention, the disadvantages mentioned are avoided by that in the reservoir just above the agitator in front of the floor outlet one is arranged in the height adjustable backdrop, and the chamber lock via a Overflow channel with a self-cleaning ring chamber with filling and pouring space communicates.

Außerdem ist es vorteilhaft, in der Kammerschleuse selbst einen Überströmkanal vorzusehen, der über eine sich selbst reinigende Ringkammer mit Füll- und Abschüttraum der Schleuse in Verbindung steht. It is also advantageous to have an overflow channel in the chamber lock itself to be provided that has a self-cleaning ring chamber with filling and pouring space the lock is in communication.

In den Fig. 1 bis 4 ist die Erfindung an einem Beispiel näher erläutert. In FIGS. 1 to 4, the invention is explained in more detail using an example.

Der Flachbodenbehälter 1 weist eine Auslauföffnung 2 auf, an welche unmittelbar eine Kammerschleuse 3 angeschlossen ist. Auf dem Boden des Behälters 1 läuft ein Rührkreuz 4 in Pfeilrichtung um, wobei unmittelbar vor der Auslauföffnung 2 eine senkrecht zum Boden stehende und in der Höhe verstellbare Kulisse 5 angeordnet ist. Auf diese Weise wird das Austraggut in einer Schichtdicke über den Auslauf 2 des Behälters gefördert, die etwa der in der Drehebene vorliegenden Projektion der Rührarm breite 4 entspricht. The flat-bottom container 1 has an outlet opening 2 to which a chamber lock 3 is directly connected. On the bottom of the container 1, a stirring cross 4 runs around in the direction of the arrow, immediately in front of the outlet opening 2, a backdrop 5 that is perpendicular to the ground and adjustable in height is arranged is. In this way, the material to be discharged is spread over the outlet in one layer 2 of the container promoted, approximately the projection present in the plane of rotation the agitator arm width corresponds to 4.

Die Kammerschleuse 3 ist in an sich bekannter Weise ausgebildet und mit einem drei- oder mehrseitigen Rotor 6 versehen, der in der Meßkammer 7 umläuft. Die in dem Flachbodenbehälter 1 verschiebbar angeordnete Kulisse 5 wird so dicht als möglich über die Arme 4 des Rührwerkes angeordnet, damit die von der Meßkammer in den Füllraum des Behälters 1 geschöpfte Luft durch die über den Auslauf 2 liegende dünne Materialschicht austreten kann. The chamber lock 3 is designed in a manner known per se and provided with a three-sided or more-sided rotor 6 which rotates in the measuring chamber 7. The slide 5, which is arranged displaceably in the flat-bottom container 1, thus becomes tight arranged as possible over the arms 4 of the agitator, so that the of the measuring chamber Air scooped into the filling space of the container 1 through the air above the outlet 2 thin layer of material can escape.

Wie Fig.3 zeigt, bildet die Frontplatte 8 der Schleuse 3 einen Überströmkanal 9, der über eine durch den in der Frontplatte 8 angeordneten Steg 13 sich selbst reinigende Ringkammer 10 am Rotor 6 mit der Meßkammer 7 und dem Schüttraum 11 der Schleuse in Verbindung steht. In F i g. 4 ist dies vergrößert dargestellt. Der je nach dem Fließverhalten des durchlaufenden Schüttgutes erforderliche unterschiedliche Spalt 14 zwischen Rotor 6 und Gehäuse der Kammerschleuse 3 kann durch Einlegen eines Zwischenringes 15 zwischen Frontplatte 8 und Gehäuse hergestellt werden. Es ist damit die Möglichkeit gegeben, daß ein eventuell noch nicht nach oben ausgetretener Luftrest nach unten über den Üb erströmkanal 9 in den Abschüttraum 11 der Schleuse entweichen kann. In den F i g. 3 und 4 ist der Rotor 6 gegenüber Fig. 1 um 1800 gedreht. As FIG. 3 shows, the front plate 8 of the lock 3 forms an overflow channel 9, which by means of the web 13 arranged in the front plate 8 itself cleaning annular chamber 10 on the rotor 6 with the measuring chamber 7 and the bulk space 11 of the Lock is in communication. In Fig. 4 this is shown enlarged. The ever different required depending on the flow behavior of the bulk material passing through Gap 14 between the rotor 6 and the housing of the chamber lock 3 can be achieved by inserting a Intermediate ring 15 are made between the front plate 8 and the housing. It is thus given the possibility that someone who has not yet stepped out Air residue down through the overflow channel 9 into the pouring space 11 of the lock can escape. In the F i g. 3 and 4, the rotor 6 is around 1800 compared to FIG turned.

Im Abschüttraum 11 der Schleuse ist ein federnder Abstreifer 12 angeordnet, der die Axialflächen des Rotors 6 gleichmäßig von angelegten Stoffen reinigt. A resilient scraper 12 is arranged in the filling chamber 11 of the sluice, which cleans the axial surfaces of the rotor 6 evenly from applied substances.
