ABSTRACT:
An improved comminutor for channels or inline conduits that carry the flow of liquid sewage which includes a semi-cylindrical concave cage formed of a plurality of axially spaced apart sections of arcuate rings or bars connected together arcuately and axially. A plurality of comb-like members are mounted at spaced intervals along the inner surface contour of the semi-cylindrical concave cage member with the teeth of its comb-like members in axial alignment with corresponding sections of the rings or bars which form the cage member. A plurality of rotatable cutting and shredding arms are mounted axially along a helical spiral like path in spaced relationship with the cage member with a plurality of comb-like members for interengaging comminuting action with radially extending portions of their respective teeth. The teeth of the cutting and shredding arms may be in engagement with each tooth of the comb-like members and each of the slotted openings of the cage member at least once during each revolution of the cutting and shredding arms.
In another embodiment of the invention the comminutor includes a hemispherical concave cage formed in a similar manner as recited above with respect to the semi-cylindrical cage. In this embodiment the rotatable cutting and shredding arms extend radially outward and have a plurality of teeth at the periphery thereof which travel along paths that conform to the inner concave surface of the hemispherical cage so as to interengage in comminuting action with the cage and the comb-like cutter teeth in a similar manner as in the semi-cylindrical cage embodiment.
