Abstract
An impeller assembly having a housing supporting a rotatable impeller. The housing has a bottom entrance opening and a top exit opening separated by a curved back wall. A liner of low friction and abrasive resistant plastic material covers the inside of the back wall. The liner is removeably mounted on the housing so that it can be replaced without taking the housing apart. The impeller has a plurality of pivoted paddle assemblies. Each paddle assembly has a generally U-shaped liner of low friction and abrasion resistant material. The impeller is adjustably mounted on the housing to provide a minimum of clearance between the liner and the outer ends of the paddle assemblies as they rotate within the housing.
Claims22
A material handling apparatus comprising:
- a housing having a first side wall, a second side wall laterally spaced from the first side wall, and an end wall secured to said side walls, said housing having a chamber with a material inlet opening and a material outlet opening spaced from said inlet opening, impeller means located within said chamber of the housing operable to move material from the inlet opening and discharge the material through the outlet opening, and means rotatably mounting the impeller means on said housing whereby upon rotation of said impeller means material moves from the inlet opening toward the outlet opening and is discharged through said outlet opening, the impeller means includes paddle assemblies having outer ends that move adjacent said end wall, the means rotatably mounting the impeller means on said housing includes means for adjusting the position of the impeller means on said housing to adjust the clearance of the outer ends of the paddle assemblies relative to said end wall.
A material handling apparatus comprising:
- a housing having wall means surrounding a chamber having an inlet opening and an outlet opening spaced from the inlet opening, impeller means located within said chamber of the housing operable to move material from the inlet opening and discharge the material through the outlet opening, and means rotatably mounting the impeller means on said housing whereby upon rotation of said impeller means material moves from the inlet opening toward the outlet opening and is discharged through said outlet opening, the means rotatably mounting the impeller means on said housing includes means for adjusting the position of the impeller means relative to said wall means.
A material handling apparatus comprising:
- a housing having laterally spaced side walls and an end wall secured to the side walls, a material inlet opening in a lower portion of said housing, a material outlet opening in an upper portion of said housing, impeller means located within said housing operable to move material from the inlet opening and discharge the material through the outlet opening, and means rotatably mounting the impeller means on said side walls whereby upon rotation of said impeller means material moves from the inlet opening through said housing and is discharged through said outlet opening, the impeller means includes a shaft, and the means rotatably mounting the impeller means on the side walls includes bearing means accommodating said shaft, and means adjustably mounting the bearing means on said side walls whereby the position of the impeller means can be adjusted relative to said end wall.
An adjusting apparatus for an impeller located within a housing of a material handling device, the housing having side walls and an end wall secured to the side walls, the impeller including a shaft, the shaft rotatably mounted on the side walls with bearings accommodating the shaft, comprising:
- support members secured to the side walls extended normal to a portion of the end wall, at least one shim between each bearing and support member, and fastener means securing the bearings and shims to the support members whereby the position of the impeller can be adjusted relative to the end wall.
