LOCKING DEVICE OF AIR-ASSISTED FEEDER Russian patent published in 1994 - IPC

FIELD: ferrous metallurgy. SUBSTANCE: air-assisted feeder has fluidization chamber 1, where casing 5 is introduced for communicating with pipeline 6 for conveyance gas. Air mixture pipeline 7 disposed in casing 5 is provided with drive 8 for rotating disk 9 secured on pipeline 7. Disk 9 is conjugated with rear wall 10 of casing. Disk 9 and rear wall 10 of casing 5 have through holes 11 and 12, which are spaced relative to casing longitudinal axis. EFFECT: increased service life and enhanced reliability in operation by elimination of blasting and jamming, which occur in prototype due to mounting stresses in locking pair formed by casing and sleeve. 2 dwg
