Abstract

Die Siebeinrichtung dient zur Nasssiebung von Papierfasersuspensionen und enthält wenigstens ein mit einer Vielzahl von Sortieröffnungen (7) versehenes Siebblech (1). Die auf der Vorderseite über die Siebfläche des Siebbleches (1) hinausragenden verschleißgeschützten Leisten (3) werden mit der Stützstruktur (2) des Siebbleches lösbar verbunden, und zwar in der Weise, dass dadurch auch das Siebblech (1) an der Stützstruktur (2) befestigt wird. Diese Verbindung ist einfach im Aufbau und leicht lösbar, z.B. um verschlissene Teile der Siebeinrichtung zu ersetzen.

Figure 00000001
The screening device is used for wet screening of paper fiber suspensions and contains at least one screening plate (1) provided with a plurality of sorting openings (7). The wear-protected strips (3) protruding from the front surface of the sieve plate (1) are detachably connected to the support structure (2) of the sieve plate, in such a way that the sieve plate (1) on the support structure (2) is attached. This connection is simple in construction and easily detachable, for example to replace worn parts of the screening device.
