The filtration container is unrotatably supported by the support base. The blade is rotated inside the filtration container by the rotary drive device, and at the same time the blade is vibrated by the blade vibration device, whereby the material to be filtered on the upper surface of the blade is made to automatically fall down by the vibration applied to the blade, and the fallen material to be filtered is pressed in a direction of the filter by the rotating blade.

Description

  The present invention relates to a filter for removing impurities contained in a paste used in powders, screen printing, and the like.

A conventional filter for filtering paste has a structure in which a blade for extruding paste from a filter is rotatably mounted in a filter container provided with a filter.
For this reason, the paste stored in the filtration container has a drawback in that the high-viscosity paste cannot be efficiently filtered by rotating on the filter with a blade during filtration. For this reason, a filter configured to fix the blade and rotate the filter container in which the paste is stored has been considered. However, such a filter has a drawback that it cannot be efficiently filtered.
