CENTRALIZED CONTROL DEVICE FOR VIBRATOR MOTOR GROUP Russian patent published in 2005 - IPC

FIELD: electrical engineering.

SUBSTANCE: proposed device that can be used to provide for sequential circular cyclic operation of centrifugal vibrators designed for cleaning bin walls from sticking loose materials in the course of their treatment and is designed to ensure desired efficiency of operating vibrators and to prevent unwanted running of other ones due to ability of adjustment and optimal number of on- and off-operations of vibrator motors during their operating cycle has push-button switch, N magnetic starters, their quantity depending on that of motors, first and N second electromechanical relays, regulated power unit, first optical triac and N second optical triacs, clear pulse shaper, pulse generator, first and second pulse counters, first and second binary-decimal decoders, multiposition single-pole switch, N NAND gates, first OR gate, AND gate, and NOT gate; newly introduced in proposed device are N - 1 multiposition single-pole switches, N INHIBIT gates, and second OR gate.

EFFECT: enhanced operating efficiency.
