CENTRIFUGAL PROJECTION DEVICE

摘要

A centrifugal projection device in which noise is suppressed by reducing the rotating vibration of an impeller and the number of times of maintenance is reduced by eliminating a liner. The centrifugal projection device comprises a drive means (3) fitted to the side part of a housing (2) through a mounting flange, the impeller (4) with a plurality of blades (13) fitted to the drive shaft of the drive means through a hub, a distributor (5) fitted to the drive shaft coaxially with each other, a control cage (6) having a rear end part fixed to the peripheral part of an opening part (18) and a tip part fixed extendedly between the distributor (5) and the blades (13), and an introducing cylinder (7) fitted to the opening part. 1) A rotation supporting member (8) for supporting the rotation of the impeller is disposed on the side part of the impeller. 2) A rotating sealing member is disposed between the base part of the distributor and the tip part of the control cage. 3) A bearing is assembled between the mounting flange and the hub while a damping body is disposed on the inner peripheral part of the mounting flange.
