Abstract

Eine neue Siebeinheit (1) zum Sieben von Pulvern und Stäuben umfasst ein Gehäuse mit einem Einlass (11), einem Siebdeckel (12), einem Auffangbecken (13) und einen Auslass (14). Zwischen Siebdeckel (12) und Auffangbecken ist eine Siebplatte (2) angeordnet. Sie ist in einer Siebplattenhalterung (21) gehalten. Oberhalb der Siebplattenhalterung (21) befindet sich eine umlaufende erste Ringspaltdüse (6) zum Einblasen von Druckluft. Im Bereich des Siebdeckels (12) ist mindestens ein Schallgeber (4) vorhanden. Er weist mit seiner Schallabstrahlung in den Siebraum (51) hinein.

Figure 00000001
A new sieving unit (1) for sieving powders and dusts comprises a housing with an inlet (11), a sieve cover (12), a collecting basin (13) and an outlet (14). A sieve plate (2) is arranged between the sieve cover (12) and the collecting basin. It is held in a sieve plate holder (21). Above the sieve plate holder (21) there is a circumferential first annular gap nozzle (6) for blowing in compressed air. At least one sound generator (4) is present in the area of the sieve cover (12). With its sound radiation, it points into the sieve chamber (51).
