CAR TIPPER DEDUSTING DEVICE Russian patent published in 1994 - IPC

FIELD: rotary type tippers. SUBSTANCE: dedusting device has aspiration apparatus with additional through vessel having two-position inlet gate, whose drive is interlocked with car tipper drive. Nominal mode of operation of dedusting device with normally partially opened gate during preparing car tipper for tipping of gondola car provides both nominal efficiency of dedusting device in intaking of dust-bearing air flow from "covering" of car tipper and "vacuum charging" of its additional vessel. Upon complete opening of gate during tipping of gondola car dedusting device with additional vessel carries out high-speed process of "peak intake" of outburst of dust from "covering" formed by falling coal flow, and then automatically changes to nominal mode of operation, following reversing return of car tipper rotor and dedusting device gate to their respective initial positions, up to the moment subsequent gondola car is to be tipped. EFFECT: increased efficiency of dedusting device by automatic adaptation of mode of operation of dedusting device to mode of operation of car tipper. 1 dwg
