Rotary kiln end sealing assembly

摘要

The present invention belongs to the field of retorting apparatus used in the field of oil shale processing, in particular the invention relates to the end sealing assembly of the rotary kiln and the improvements of the end sealing (16); whereas the first and second casing ring (2, 3) used in the end sealing compose of at least four segment, and onto both sides of the rotating casing ring (1) a rectangulary cut hollow (81, 91) for lubricants has been formed; and on the side that is assembled with the rotating casing ring of the first and second casing ring (2, 3), accordingly, a hollow (82, 93) has been formed for lubricants, which in the making face the corresponding hollow (81, 91) of the casing ring, forming lubricant channels (8, 9) between the casing ring (1) of the end sealing assembly and the first and second casing ring (2, 3).

主权项

1. An end sealing assembly of a rotary kiln that comprises:
a first flange attached to the outside of the end of a rotating drum of the rotary kiln and to which a rotating casing ring is attached, rotating with the rotating drum; a second flange attached to the outside end of a fixed input/output unit of the rotary kiln and onto which a first fixed casing ring is attached and a second fixed casing ring is attached with fixing devices; whereas the fixing devices include a spring, a fixing bolt and a fixed flange onto which the second fixed casing ring is attached, wherein the first fixed casing ring and the second fixed casing ring are both made out of at least four segments coupled together to arrange respectively the first fixed casing ring and the second fixed casing ring arranged on opposite circumferential sides of the rotating casing ring attached to the rotating drum whereas hollows for lubricant are onto both sides of the rotating casing ring; and correspondingly, a hollow with a trapezoidal cross section for lubricant is formed onto the side of the first fixed casing ring and the second casing ring to be assembled with while composing the rotating casing ring with the first and second casing ring; and such that when forming the end sealing assembly, a first lubricant channel is made out of the hollows between the rotating casing ring and the first fixed casing ring, and a second lubricant channel is made out of the hollows between the rotating casing ring and the second fixed casing ring.
