摘要

The invention relates to a screening device comprising a supporting framework which carries at least one vibrating shell (carcass) equipped with a frame carrying a screen. The frame (10) is in the form of a rigid structure which carries a screen (11). The screen (11) is connected to this frame (10) by means of an adhesive joint (seal) (12). A sonotrode (13) coupled to an electroacoustic converter (14) is fixed to the frame (10) by means of screws (15). The ultrasonic vibrations generated by the sonotrode are transmitted to the screen (11) via the frame (10) and the adhesive joint (12). This device makes it possible to use a single ultrasonic-vibration generator, whilst allowing rapid replacement of the screen.
