Agitator filter

The agitator chute is used for the mechanical solid-liquid separation of suspensions with low to high solids content. The solids are retained by a horizontally arranged permeable sieve bottom and the solids form a filter cake.

The separation process is accelerated by an overpressure in the upper process chamber or by a vacuum below the filter layer, or ideally by both.

A height-adjustable bar agitator can smooth or roughen the surface of the filter cake depending on the process requirements. This also makes it possible to re-suspend the filter cake.

The filter cake can be impinged with different washing liquids by means of one or more nozzle rings in the upper part and thus certain fractions can be liquefied and washed out of the filter cake.

By means of the agitator, the finished treated filter cake is then discharged via a side discharge valve and fed for further processing.
