Thermally decoupled mixer

摘要

The present invention provides a mixer assembly (28) including a mixer element (30) and a plurality of scoops (32) attached around a circumference of the mixer element (30) via a combination of sliding brackets (36, 38) and fixed brackets (34). The sliding brackets (36, 38) provide attachment and allow relative movement between the plurality of scoops (32) and the mixer element (30) while the fixed brackets (34) provide only attachment between the mixer element (30) and the plurality of scoops (32). A first sliding bracket (36) includes a first flange (40) that is fixedly mounted to the mixer element (30) and a second flange (44) that is biased against a surface (46) of the scoop (32). A second sliding bracket (38) is fixedly mounted to the mixer element (30) and adjustably mounted to the scoop (32). The second sliding bracket (38) includes an attachment hole (52) and the scoop (32) includes an adjustment slot (60). A fastener assembly (56) including a spacer (54) is received within the adjustment hole (52) and the adjustment slot (60) to allow relative movement between the mixer element (30) and the scoop (32).
