US 8,544,782 B2 · Liner for drum and method of assembly

Abstract

A lined drum includes a drum having a wall with an inner surface. The lined drum also includes a plurality of liner segments, each liner segment having inner and outer opposing surfaces, opposing side edges, and opposing end edges, the outer surface of the liner segment facing the inner drum surface and the side edges of adjacent liner segments being spaced from each other to define a space therebetween, and at least one retainer having opposing side edges overlapping the side edges of the adjacent liner segments, the at least one retainer attached to the wall of the drum in the space between the side edges of the adjacent liner segments. The lined drum may also include a plurality of bar segments, each bar segment attached to the wall of the drum and at least one retainer.

A lined drum comprising:

a drum with a longitudinal axis including a wall with an inner surface;
a plurality of liner segments, each liner segment having inner and outer opposing surfaces, opposing side edges aligned with the longitudinal axis, and opposing end edges, the outer surface of the liner segment facing the inner drum surface and the side edges of adjacent liner segments being spaced from each other to define a space therebetween;
at least one retainer having opposing side edges overlapping the side edges of the adjacent liner segments on the inner surface of the liner segments, the at least one retainer attached to the wall of the drum in the space between the side edges of the adjacent liner segments with the side edges of both the adjacent liner segments disposed between the retainer and the wall to attach the adjacent liner segments to the wall and the side edges of both the adjacent liner segments free to move within the space;
and
a drive coupled to the drum to rotate the drum about an axis collinear or non-collinear with the longitudinal axis.

The method of assembling a liner in a drum having an inner surface, the method comprising:

disposing a liner segment having inner and outer surfaces, opposing side edges, and opposing end edges in the drum with the outer surface of the liner segment facing the inner surface of the drum;
disposing an adjacent liner segment having inner and outer surface, opposing side edges and opposing end edges in the drum with the outer surface of the adjacent liner segment facing the inner surface of the drum with one of the side edges of the adjacent liner segment spaced from one of the side edges of the liner segment to define a space between the liner segments;
attaching a retainer having opposing side edges overlapping the side edges of the liner segments on the inner surface of the liner segments to the wall of the drum in the space between the side edges of the liner segments with the side edges of both the adjacent liner segments disposed between the retainer and the wall to attach the adjacent liner segments to the wall and the side edges of both the adjacent liner segments free to move within the space;
and
rotating the drum about an axis collinear or non-collinear with a longitudinal axis of the drum.
