Device for automatic regulation of the process of separating froth concentrate from gangue in a floatation machine

摘要

The automatic regulator device comprises a channel for measuring the level and density of pulp in the chamber of a floatation machine, in which two bubbling pipes are in communication with a differential pressure pickup connected to the input of a frother flow-rate regulating channel and to one input of a correction unit whose other input is connected to a pressure pickup communicating with one of the bubbling pipes. The output of the correction unit is connected to the input of a circuit designed to regulate the rate of flow of water with frother in a pulp level stabilizing channel, the output of said circuit being connected to an actuator valve installed on a pipeline feeding water with frother and furnishing a control signal with respect to a pulp level deviation from a preset value. A water-and-frother flow transducer is connected to the input of a circuit designed to regulate the gangue discharge rate in the pulp level stabilizing channel, the output of said circuit being connected to the drive of the actuator valve installed on a gangue discharge branch pipe, said output developing a control signal with respect to a deviation of the water-and-frother flow rate from a preset value.
