Abstract
A bulk materials pump feeder having a housing and a rotatable drive rotor mounted in the housing for transferring material introduced into the housing through an inlet to an outlet for discharge of the material from the housing. The drive rotor has a hub and a plurality of drive discs extending away from the hub toward an inner wall of the housing. To reduce the tendency of material passing through the housing to wedge between the inner wall of the housing and the circumferential edges of the drive discs, the distance between the circumferential edges of the drive discs and the inner wall of the housing increases from the inlet of the housing to the outlet of the housing in the direction of rotation of the drive rotor.
Claims20
A bulk materials pump feeder comprising:
- a housing having:
- (a) an inlet,
- (b) an outlet, and
- (c) an inner wall extending from said inlet to said outlet;
- and
- a drive rotor having:
- (a) a hub rotatable about a rotation axis, and
- (b) a plurality of drive discs extending away from said hub toward said inner wall of said housing, with the distance between the circumferential edges of said drive discs and said inner wall of said housing increasing from said inlet of said housing to said outlet of said housing in the direction of rotation of said drive rotor;
- said inner wall of said housing, said drive discs, and said hub defining a materials transfer duct through which material is transferred from said inlet of said housing to said outlet of said housing.
A bulk materials pump feeder comprising:
- a housing having:
- (a) an inlet through which material is introduced into said housing,
- (b) an outlet through which material is discharged from said housing, and
- (c) an inner wall extending from said inlet to said outlet;
- and
- a drive rotor mounted within said housing for rotation about a rotation axis for transferring material introduced into said housing through said inlet of said housing to said outlet of said housing for discharge from said housing, said drive rotor having:
- (a) a hub rotatable, and
- (b) a plurality of drive discs extending away from said hub toward said inner wall of said housing, with the distance between the circumferential edges of said drive discs and said inner wall of said housing increasing from said inlet of said housing to said outlet of said housing in the direction of rotation of said drive rotor.
