Abstract

PURPOSE: To break contained foreign matters repeatedly by an arrangement wherein a portion in which the front of a periphery of an impeller base is positioned rear from the front of a back wall of a casing and another portion in which it is not positioned rear are provided, and further a cutter is provided on the casing front wall.
CONSTITUTION: A concavity 8 in which a base 13 of an impeller 12 is enclosed rotatably is provided on a back wall 4 of a casing 1; a portion 13a in which the front of a periphery of the base 13 is positioned rear from the front of the casing back wall 4 at a periphery of the concavity 8 and another portion 13b in which it is not positioned rear are provided for the impeller 12. Then, a cutter 16 opposite to a blade 14 with a gap left a little therefor is provided on the casing front wall 5. Liquid is now fluidized spirally in the neighborhood of an outer periphery of the impeller 12, contained foreign matters can be broken repeatedly, and an interval between the blade 14 and the casing front wall 5 can be taken sufficiently large, thus suppressing an overload operation effectively.
