Document Type and Number:
Japanese Patent JPS6213518
Kind Code:
B2
Abstract:
A centrifugal pump which has a single-blade impeller and is used particularly for the transport of long-fibered deposited solids, for example, in sewage. The pump impeller discharge end lies in a radial plane adjacent a housing wall there being a clearance between the housing wall and the discharge end. The blade face is directed to the housing wall to form an acute angle with that wall, the line between the outer extremity of the blade and the discharge end of the blade forms an acute angle relative to the axial direction of the impeller. The front edge of the impeller is sharpened and provides a moving shearing edge, and the housing wall provides a stationary shearing edge so that medium pumped into the impeller can be cut and disintegrated between these edges. The angles defined facilitate drawing the long-fibered solids into the area for shearing and disintegration.
