ABSTRACT:
A filtering device used to filter the slurry is disclosed, including a crossflow fan within the filter housing, and a driving mechanism relative to the crossflow fan under the filter housing to drive the crossflow fan spinning to agitate the slurry in the filter housing, so as to prevent the particles in the slurry from adhering to the surface of the filter. The filtering device further includes a spoiler between the crossflow fan and the filter, so that larger particles remain circulating somewhere between the tip of the spoiler and the crossflow fan, instead of flowing to the filter, to prolong the lifetime of the filter.
