Description
(54) УСТРОЙСТВО ДЛЯ АВТОМАТИЧЕСКОГО ДОЗИРОВАНИЯ(54) DEVICE FOR AUTOMATIC DOSING
РЕАГЕНТОВREAGENTS
II
Насто щее изобретение относитс к флотационному обогащению .руд и может быть применено при флотации руд цветных металлов .The present invention relates to flotation enrichment of pounds and can be applied in the flotation of non-ferrous metal ores.
Известно устройство дл дозировани , в котором дополнительно к основной и на рассто нии по фронту флотации от нее устанавливаетс втора электродна пара, состо ща из индикаторного и вспомогательного электродов, а реагент в процессе дозируетс по разности потенциалов основной и дополнительной электродных пар. Этим достигаетс повышение точности дозировани за счет устранени мешающих факторов самой контролируемой среды 1.A device for dosing is known, in which a second electrode pair consisting of indicator and auxiliary electrodes is installed in addition to the main and at a distance along the flotation front from it, and the reagent in the process is metered according to the potential difference of the main and additional electrode pairs. This achieves an increase in dosing accuracy by eliminating the interfering factors of the controlled environment itself 1.
Недостатком устройства вл етс то, что выход из стро одного из индикаторных электродов приводит к нарушению работы всей системы в целом. Следовательно, характеристики точности и надежности низкие.The disadvantage of the device is that the failure of one of the indicator electrodes leads to a malfunction of the entire system. Consequently, the characteristics of accuracy and reliability are low.
Известно устройство дл автоматического дозировани реагентов в процессе флотации , содержащее индикаторный и вспомогательный электроды, св занные с преобразователем , регул тор, св занный с дозатором реагентов 2.A device for automatically metering reagents in the flotation process is known, comprising indicator and auxiliary electrodes associated with a converter, a regulator associated with a reagent dispenser 2.
Недостатком известного устройства вл етс низка точность и надежность дозировани .A disadvantage of the known device is the low accuracy and reliability of dosing.
Цель изобретени - повыщение точности и надежности дозировани .The purpose of the invention is to increase the accuracy and reliability of dosing.
Поставленна цель достигаетс тем, что устройство снабжено последовательно соединенными блоком формировани посто нного сигнала и переключателем выбора входного сигнала, входы последнего соединены с преобразовател ми , а выход с регул тором расхода реагентов.The goal is achieved by the fact that the device is equipped with a series-connected DC signal generation unit and an input signal selection switch, the inputs of the latter are connected to transducers, and the output is controlled by a reagent consumption controller.
На чертеже представлена блок-схема устройства .The drawing shows the block diagram of the device.
В одной из камер флотационной машины 1 установлена измерительна чейка,A measuring cell is installed in one of the chambers of the flotation machine 1,
содержаща вспомогательный 2 и первый 3 и второй 4 индикаторные электроды. Разность потенциалов электродов 3 и 2 подаетс через преобразователь 5 и переключатель 6 выбора входного сигнала на регул тор 7, управл ющий дозатором реагента 8.containing auxiliary 2 and first 3 and second 4 indicator electrodes. The potential difference of the electrodes 3 and 2 is fed through the converter 5 and the input selection switch 6 to the regulator 7, controlling the reagent dispenser 8.
Индикаторный электрод 3 в паре с электродом 4 через преобразователь 9 и блок 10 формировани посто нного сигнала подключены к другим входам переключател 6 выбора входного сигнала.The indicator electrode 3 in tandem with the electrode 4 through the converter 9 and the unit 10 of forming a constant signal are connected to other inputs of the switch 6 for selecting the input signal.
