Abstract
Description
Die Anmeldung betrifft eine Zellenradschleuse mit von außen zugänglicher und montierbarer Abdichtung. In der Verfahrenstechnik kommt es häufig vor, daß die verschiedensten Materialien aus einem Silo oder einem Behälter geregelt ausgetragen werden müssen. Diese Aufgabe wird oftmals von Zellenradschleusen übernommen. Bei gut fließenden Stoffen müssen diese Schleusen im Durchgang dicht ausgeführt sein, um ein unkontrolliertes Durchfließen zu verhindern. Die hier angemeldete Schleusenart ermöglicht den Aufbau solch dichter Schleusen mit dem Vorteil, daß die Instandhaltung oder eine Reparatur im Bereich der Abdichtung ohne großen Aufwand möglich ist.The application relates to a rotary valve with an externally accessible and mountable Seal. It is often the case in process engineering that the most varied Materials from a silo or a container must be discharged in a controlled manner. This The task is often taken over by cellular wheel sluices. With well flowing fabrics these locks in the passageway must be tight to prevent uncontrolled To prevent flow through. The lock type registered here enables the construction of such dense locks with the advantage that maintenance or repair in the area of Sealing is possible without much effort.
Dieser Vorteil wird durch ein von außen zugängliches Dichtelement erreicht. Dazu hat das Schleusengehäuse parallel zur Rotorachse eine oder mehrere Spaltöffnungen mindestens über die Länge des Rotors. In jeder dieser Spalten wird ein Dichtelement eingepaßt. Die Außenseite des Dichtelementes ist größer als der Spalt und wird auf das Schleusengehäuse aufgelegt und dort befestigt. Dadurch wird verhindert, daß das Dichtelement während des Betriebs in den Schleusenraum eingezogen werden kann. Um zu verhindern daß das Dichtelement nach außen gedrückt werden kann sind verschieden Verfahren möglich. Im einfachsten Fall kann diese Abdichtung z. B. über Stellschrauben nachgestellt werden. Weiterhin besteht die Möglichkeit über pneumatische oder elektrische Antriebe eine Außenkraft auf das Dichtelement wirken zu lassen, die permanent oder nur beim Stillstand der Zellenradschleuse wirken. Weiterhin kann von außen das Dichtelement mit Luftdruck beaufschlagt werden, der das Dichtelement gegen die Lamelle des Rotors preßt und somit die Schleuse im Durchgang abdichtet.This advantage is achieved by an externally accessible sealing element. That has Lock housing parallel to the rotor axis at least one or more stomata the length of the rotor. A sealing element is fitted in each of these columns. The Outside of the sealing element is larger than the gap and is on the lock housing put on and fastened there. This prevents the sealing element during the Operation can be drawn into the lock room. To prevent that Different methods can be used to press the sealing element outwards. In the simplest case, this seal can, for. B. can be adjusted using adjusting screws. There is also the option of pneumatic or electric drives To allow external force to act on the sealing element, either permanently or only when the Cell wheel lock act. Furthermore, the sealing element with air pressure from the outside are applied, which presses the sealing element against the lamella of the rotor and thus the Seals in the passage.
Der Stillstand der Schleuse wird so gesteuert, daß jeweils ein oder mehrere Lamellenpaare an dem Dichtelement anliegen. Dazu ist an der Rotorachse ein entsprechender Geber vorgesehen, der die entsprechenden Signale liefert.The standstill of the lock is controlled in such a way that one or more pairs of slats each rest against the sealing element. For this purpose, a corresponding encoder is provided on the rotor axis, that delivers the appropriate signals.
Claims (5)
In einem Gehäuse dreht ein Rotor mit aufgesetzten oder eingegossenen Taschen längs zur Rotationsachse. Die obenliegenden Taschen werden durch die anstehende Materialsäule gefüllt. Durch die Rotation werden die Taschen bei Erreichen der Auslaßöffnung entleert und bewegen sich wieder in die Füllzone. Der Patentanspruch ist dadurch gekennzeichnet, daß die Abdichtung des Füll- zur Entleerzone über Dichtelemente am Gehäuse erfolgt. Die Begrenzung der Taschen voneinander wird im folgenden mit Lamellen bezeichnet.1. Rotary valve with sealing device accessible from the outside The structure of a rotary valve is described as follows:
In a housing, a rotor with attached or cast-in pockets rotates along the axis of rotation. The pockets above are filled by the material column. As a result of the rotation, the pockets are emptied when they reach the outlet opening and move back into the filling zone. The patent claim is characterized in that the filling to the emptying zone is sealed by means of sealing elements on the housing. The delimitation of the pockets from one another is referred to below as slats.
