SYSTEM FOR CONTROL OF LOOSE COMPONENTS BLENDING Russian patent published in 2009 - IPC G05D11/00 

FIELD: physics.

SUBSTANCE: system for control of loose components blending additionally comprises the following components for blending of uncontrolled loose component of mixture: serially connected hopper-accumulator tank and transporter track for component supply into blended stack, serially connected scales installed on transporter track, and unit-accumulator counter for information summation on current weight of component. To blend every of dosed loose components of mixture, there are serially connected hopper-accumulator tanks according to the number of mentioned components, feeders, transporter tracks of components supply into blended stack, scales serially connected in compliance with mentioned components and installed on transporter tracks, and unit-accumulator counters for information summation on current weight of every dosed components, multiplication units that are serially connected in compliance with the number of mentioned components, control inputs of which are connected to output of unit for comparison of ratios of the amounts of current and required uncontrolled and dosed loose components of mixture, units of PID-controllers, other outputs of which are connected to appropriate information outputs of scales of every dosed loose components, and feeders, and also unit-information table, inputs of which are connected to appropriate information outputs of scales of uncontrolled loose component, scales of every dosed loose component of mixture and unit-setter for operator to set required ratio of scales of uncontrolled and dosed loose components of mixture, at that the second input of unit for comparison of ratios of the amounts of current and required uncontrolled and dosed loose components is connected to appropriate information output of unit-accumulator counter for information summation on current weight of uncontrolled loose component of mixture, and the first and second information outputs of unit-accumulator counters of information summation on current weight of every dosed components of mixture are connected accordingly to the third input of unit for comparison of ratios of the amounts of current and required uncontrolled and dosed loose components of mixture and input of unit-setter for operator to set required ratios of mixture components weights, the other information output of which is connected to appropriate inputs of multiplication unit.

EFFECT: increased efficiency of control and improved productivity.
