Description

PATENTAMT:PATENT OFFICE:

Die in dem Zusatz-Patent No. 49245 bezw. dem Zusatz-Patent No. 50343 bezeichneten Spülrohre p1 zum Reinigen der Filterflächen erfüllten ihren Zweck nur da, wo man die SpUlflüssigkeit unter verhältnifsmäfsig hohem Druck anwenden kann. Um nun die Reinigung durch Spülung auch da vornehmen zu können, wo man überhaupt nicht oder nur über geringen Druck verfügt, werden die in beiliegender Zeichnung dargestellten Einrichtungen angewendet. The features described in Supplementary Patent No. 49245 or the additional patent no. 50343 designated flushing pipes p 1 for cleaning the filter surfaces only fulfilled their purpose where the flushing liquid can be used under relatively high pressure. In order to be able to carry out cleaning by flushing where there is no pressure at all or only low pressure, the devices shown in the accompanying drawing are used.

In den aus dem Zusatz - Patent No. 49247 bekannten, um die Filtertrommeln drehbaren Rahmen q werden an Stelle der dort benutzten Bürsten. i Schaufeln w eingesetzt, Fig. 4 bis 7, welche die Filterflächen nicht berühren, aber so gestellt sind, dafs sie die SpUlflüssigkeit bei einer bestimmten Drehungsrichtung des Rahmens unter einem spitzen Winkel gegen die abzuspülenden Filterflächen schleudern. Zu diesem Zwecke können z. B. die zwischen den Trommeln b angeordneten Schaufeln w auf der einen Seite des Rahmens q gegen die eine Filterfläche, die der anderen Rahmenseite gegen die gegenüberliegende Filterfläche gerichtet sein, oder es kann auch jede einzelne Schaufel dergestalt geformt sein, dafs die eine Hälfte der Filterfläche die. Spülflüssigkeit nach der einen, die andere Hälfte sie nach der anderen Seite wirft. In diesem letzten Falle müssen selbstredend die entsprechenden Schaufelflächen in dem einen Rahmenarm gegen diejenigen des anderen Rahmenarmes versetzt sein, so dafs etwa die dem Rahmen zunächst liegenden Schaufelhälften die Spülflüssigkeit gegen den äufseren ringförmigen Theil bei den benachbarten Filterflächen , die der Achse zunächst liegenden Schaufelhälften die Flüssigkeit gegen die entsprechenden inneren Ringflächen der betreffenden Filtertrommeln schleudern.In the additional patent no. 49247 known frames q that can be rotated about the filter drums are used in place of the brushes used there. i blades w inserted, Fig. 4 to 7, which do not touch the filter surfaces, but are set so that they throw the flushing liquid at a certain direction of rotation of the frame at an acute angle against the filter surfaces to be washed. For this purpose z. B. arranged between the drums b blades w on one side of the frame q against one filter surface, the other side of the frame against the opposite filter surface, or each individual blade can be shaped in such a way that one half of the filter surface the. Rinsing liquid to one side, the other half tossing it to the other side. In this last case, the corresponding blade surfaces in one frame arm must of course be offset from those in the other frame arm, so that the blade halves closest to the frame transfer the flushing liquid against the outer ring-shaped part of the adjacent filter surfaces, and the blade halves closest to the axis transfer the liquid hurl against the corresponding inner ring surfaces of the respective filter drums.

Auf diese Weise wird ein förmliches Abschälen der. auf den Trqmmelflächen niedergeschlagenen Faserschichten und dadurch eine wirksamere Reinigung der Trommeln, als bisher, erzielt.In this way, the. down on the rubble surfaces Fiber layers and thereby a more effective cleaning of the drums than before.

Versieht man die äufseren, über den Trommelrand hinausragenden Enden der Schaufeln mit einem winkelförmigen Ansatz w1, so erhält die Spülflüssigkeit bei der Drehung der Schaufeln an dieser "Stelle eine Ablenkung von der angenommenen Bewegungsrichtung gegen den Trommelrand, wodurch ein besseres Loslösen der Faserschichten von den Aufsenrändern der Trommeln erzielt wird.If the outer ends of the blades protruding beyond the drum edge are provided with an angular extension w 1 , the rinsing liquid is deflected from the assumed direction of movement towards the drum edge when the blades are rotated at this point, which means that the fiber layers are better detached from the Outer edges of the drums is achieved.

Da zum Zwecke der beschriebenen Reinigungsarbeit das Filter nur zum Theil mit der Spülflüssigkeit gefüllt zu sein braucht, so empfiehlt es sich, den Filtertrommeln durch ein entsprechendes Vorgelege q* q4 q5 qe q1 eine langsame Drehbewegung entgegen derjenigen des sich schneller drehenden Rahmens q zu ertheilen, damit alle Theile der wirksamen Filterflächen eine gleichmäfsige Behandlung er- ■ leiden.Since the filter only needs to be partially filled with the rinsing liquid for the purpose of the cleaning work described, it is advisable to give the filter drums a slow rotating movement against that of the faster rotating frame by means of an appropriate backing q * q 4 q 5 q e q 1 q to be given, so that all parts of the effective filter surfaces suffer an even treatment.
