FILTER

摘要

A filter for filtering a solid-liquid mixture containing solids (7), such as powder, minute objects, etc., so as to separate the mixture into the liquid and the solids. The filter is constructed from an outer container (2); an inner container (1) having outflow holes (1a), for temporarily storing the solid-liquid mixture to be filtered; water discharge grooves (1b) and air vent grooves (1c), which are formed in the outer side-face of the inner container (1); and a discharge opening (2a) formed in the outer container (2), for discharging a liquid (8) guided to a bottom portion of the outer container (2) to outside the outer container. The width of the water discharge grooves (1b) is smaller than the size of the solids (7).
