Description
viH6o при наличии юистемы автоматической стабилизации расхода вентилирующего воздуха с воздействием иа указанный шибер задатчик регул тора системы стабилизации.viH6o in the presence of the system of automatic stabilization of the flow rate of ventilating air with the impact of the indicated gate of the regulator of the stabilization system.
В качестве датчика 7 степени измельчени готового .продукта (МОжет быть применен непоередственйо датчик грубости помола или удельной .поверхности готового продукта или датчик сигнала косвенной переменной, например электроакустического сигнала.As a sensor 7, the degree of grinding of the finished product (An immediate coarseness sensor of grinding or specific surface area of the finished product or a signal sensor of an indirect variable, such as an electroacoustic signal, may be used).
В качестве датчика 8 1производительио1сти мельницы может быть использован расходомер ГОТ01ВОГО продукта, счетчик числа переключений iKaMeipHoro насоса, датчик расхода исходного материала или датчик аюложени регулирующего органа дозирующего устройства .As the sensor 8 1 of the mill can be used the flow meter of the READY product, the pump switching number counter iKaMeipHoro, the flow sensor of the source material or the metering sensor of the regulator of the metering device.
Исходный материал -через дозирующий блок 1 поступает IB мельницу 2. Вентил тор 3 обеспечи1вает движение вентилирующего .воздуха -через мельницу 2 и :воздухо1воды 4 и 5. Расход вентилирующего воздуха регулируетс при помощи регулирующего органа. Степень из.мельчени готового продукта измер етс датчиаюм 7. Сигнал датчика 7 поступает на вход регул тора 9, выход которого подключен к регулирующему органу дозирующего -блока. Регул тор 9 осуществл ет автоматическое измерение расхода исходного материала таким образом, чтобы обеспечивать стабилиза.цию степени измельчени готового продукта.The source material - through the dosing unit 1 enters IB mill 2. Fan 3 ensures the movement of the ventilating air. - through mill 2 and: air ducts 4 and 5. The flow of the ventilating air is controlled by the regulator. The degree of grinding of the finished product is measured by sensor 7. The signal of sensor 7 is fed to the input of controller 9, the output of which is connected to the regulator of the metering unit. The regulator 9 performs automatic measurement of the flow rate of the starting material in such a way as to stabilize the degree of grinding of the finished product.
Сигнал датчика 8 производительности поступает па вход сглаживающего фильтра 10, выход которого подключен к экстремальному регул тору 11. Выход экстремально.го регул тора 1 соединен с регулирующим органом 6 расхода вентилирующего воздуха. Экстремальный регул тор работает в режиме поиска максимума входного сигнала и И31мен ет расход вентилирующего воздуха так, чтобы производительность мельницы достигла .максимального значени . Наличие в схеме устройства сглаживающего фильтра 10 повышает эффективность поиска экстремума, так как устран ет вли ние случайных флуктуации производительности на работу экстремального регул тора.The signal from the performance sensor 8 is supplied to the input of the smoothing filter 10, the output of which is connected to the extreme controller 11. The output of the extreme regulator 1 is connected to the regulator 6 of the ventilation air flow. The extreme controller operates in the mode of searching for the maximum of the input signal and E31 changes the flow rate of the ventilation air so that the mill performance reaches a maximum value. The presence in the circuit of a smoothing filter device 10 increases the efficiency of the search for an extremum, since it eliminates the effect of random performance fluctuations on the operation of an extreme controller.
Дл по снени принципа работы устройства .рассмотрим случай, когда мельница работает в режиме, соответствующем левой ветви Э|1 стремалы1ой зависимости производительности от расхода вентилирующего воздуха. Пусть экстремальным регул тором дано пробное воздействие, соответствующее увеличению расхода вентилирующего воздуха. Увеличение расхода воз.духа способствует улучшению условий помола и уменьшению грубости помола готового продукта. Уменьщение грубости помола фиксируетс датчиком 7, и регул тор 9 вырабатывает воздействие, направленное на компенсацию этого изменени за счет увеличени расхода исходного -материала . Увеличение производительности мельницы в свою очередь фиксируетс датчиком 8 и экстремаль-ный регул тор 11 выбирает воздействие , паправлевное «а увеличение расхода вентилирующего воздуха.In order to clarify the principle of operation of the device. Let us consider the case when the mill operates in the mode corresponding to the left branch E | 1 of the dependence of productivity on the flow of ventilating air. Let an extreme regulator be given a trial action corresponding to an increase in the flow rate of ventilating air. Increasing the air flow rate improves the grinding conditions and reduces the coarse grinding of the finished product. The reduction in the coarseness of the grinding is detected by the sensor 7, and the regulator 9 produces an action aimed at compensating for this change by increasing the consumption of the source material. The increase in the productivity of the mill, in turn, is fixed by the sensor 8 and the extreme regulator 11 selects the influence right through the increase in the flow rate of the ventilating air.
При переходе объекта в режим, соответствующий правой ветв-и экстремальной характеристики , увеличение расхода вентилирующего воздуха приводит к увеличению грубости пО:МОла готового П-родукта, вследствие чего регул тор 9 осуществл ет уменьщение расхода исходного -материала, а экстремальный регул тор 11 при уменьщении сигнала датчика производительности 8, -сглаженного фильтром 10, 01существл ет раверс и измен ет положение регулирующего органа 6 в сторону уменьшени -расхода вентилирующего воздуха .When the object switches to the mode corresponding to the right branch and extreme characteristics, an increase in the flow rate of the ventilation air leads to an increase in the roughness of the PO: Moll of the finished product, as a result of which the regulator 9 reduces the flow rate of the source material, and the extreme regulator 11 decreases The signal of the capacity sensor 8, smoothed by the filter 10, 01, is reversed and changes the position of the regulator 6 in the direction of decreasing the consumption of ventilation air.
Оптимальное значение расхода вентилирующего воздуха измен етс при изменении свойств размалываемого -материала, условий помола, а также при из-менении заданногоThe optimum value of the flow rate of ventilating air changes with changes in the properties of the grinded material, grinding conditions, as well as changes in the set
значени степени измельчени готового продукта , поддерживаем-ого репул тором 9. При изменени-и указанных факторов найденное экстремальны регул тором значение расхода воздуха перестает быть оптимальным, иthe degree of grinding of the finished product, supported by the repulator 9. When changing and these factors, the value of the air flow found by the extreme controller is no longer optimal, and
экс71ремальный регул тор осупхествл ет поиск нового з-начени расхода вентилирующего воздуха, соответствующего максимальной производительности при изменившихс усло-ви х работы агрегата.The extermination controller regulates the search for a new ventilation flow rate, corresponding to the maximum capacity under the changed operating conditions of the unit.
