Abstract: A microplastic filter includes a housing including an inlet configured to receive water. The microplastic filter also includes a fine filter disposed to rotate within the housing and configured to filter residues from the water. The microplastic filter further includes an inside wiper disposed within the fine filter. The inside wiper includes a center post disposed along a rotational axis of the fine filter and a helical curved wall spirally extending between the center post and the fine filter, where the helical curved wall is configured to guide a portion of the water to backflow through the fine filter and force away at least some filtered residues from pores of the fine filter to prevent fouling or clogging of the fine filter. In addition, the microplastic filter includes an outside wiper spirally disposed around the fine filter and configured to dislodge other filtered residues from the fine filter as the fine filter rotates.

Abstract: A filter device for plasticized molding material includes a filter body and an adjusting body movable relative to the filter body between a first position and a second position. In the first position, a first flow path for the plasticized molding material is defined by channels in the filter body and in the adjusting body, and the first flow path is formed such that the plasticized molding material is filtered. In the second position, a second flow path for the plasticized molding material is defined by channels in the filter body and in the adjusting body, and the second flow path is formed such that the channels and/or a filter element are at least partially flushed and/or backflushed.
